This guide makes one from an empty library to a link someone else can open. It takes about ten minutes. ## Open the library Sign in at [puni.design](https://puni.design). The library is the first thing you see: your scenes as tiles and a search. ## Create a scene Press **+** next to your avatar and choose **New scene**. Add an object with **+** in the objects rail, then **Add object…**, or use a [connected agent](https://puni.design/docs/agents/connect) to author it. ## Shape an object Select an object by clicking it on the stage or in the objects rail on the left. The inspector on the right opens its selected object’s named tab. 1. Change **Color** and **Material** under Properties. The stage updates as you type. 2. Drag the object with the move tool (**W**), or type a position under Transform. 3. Press **F** to fit the scene to the view. Every change is one undo step. Press **⌘Z** to go back, **⌘⇧Z** to go forward. ## Give it motion Open the timeline with **T** or the chevron at the right of the timeline controls. Select an object, right-click it, and choose **Spin**. A track appears with one clip. Press **Space** to play it. A behavior is faster than a track for small life. In the inspector, under **Behavior**, choose **Idle** and press **Add**: the object breathes on its own clock. ## Save Puni saves as you work. The top bar says so, and press **Save checkpoint** in Version history to keep a version you can return to; an agent’s edits keep one automatically. Press **⌘S** to save now. ## Share a link Press **Share** in the top bar and choose **Share a link…**, then press **Create new**. It makes a link to this exact version; press **Copy link**. Anyone with the link can watch the scene, orbit it, and, if you allow it, remix it into their own library. Read [Scenes and the library](https://puni.design/docs/home/scenes) next to see where the scene went and how versions work. --- Source: https://puni.design/docs/home/scenes Raw Markdown: https://puni.design/docs/home/scenes.md --- description: >- Where your scenes live, what a tile shows, how versions and checkpoints are kept, and how to find, archive and search scenes. figure: null icon: null order: 2 redirects: [] sourceRefs: - apps/app/src/features/gallery/gallery-home.tsx - apps/app/src/features/gallery/project-tile.tsx - packages/backend/convex/studio/queries.ts - apps/app/src/features/gallery/library-search-dialog.tsx - packages/backend/convex/studio/mutations.ts - apps/app/src/features/studio/use-cover-capture.ts - apps/app/src/features/studio/composition-history.tsx status: available surfaces: - web title: Scenes and the library verifiedAt: '2026-10-12' --- The library is every scene you own, newest first. Each tile carries the scene's cover, its name, and when it was last edited. [Open in Puni](https://puni.design/) to see your library. ## The tabs | Tab | Shows | | --- | --- | | All | Every live scene | | Recent | Scenes edited in the last seven days | | Archived | Scenes you put away; links to them stop working until restored | **Search** (or **/**) opens a dialog that finds scenes by name or description. ## A tile's menu Right-click a tile. | Item | What happens | | --- | --- | | Open, Open in new tab | Opens the studio | | Rename | Renames in place | | Duplicate | A new scene with the same contents | | Copy → Link, Scene ID, Puni JSON | The scene's address, its ID, or the whole document on your clipboard | | Share | Opens the share dialog in the studio | | Archive, Restore | Puts the scene away, or brings it back | ## Versions Every save is a revision. **Version history** in the scene menu lists the checkpoints you saved and those kept before an agent’s edits. Restoring a checkpoint is itself a new revision; nothing is lost. ## Covers A cover is the picture on the tile and on a share link's card. The studio captures it from the stage shortly after a save, once the stage is at rest, so it always shows the saved scene. A scene saved from a browser that cannot draw 3D has its cover drawn by Puni's server instead; where the server cannot, the last good cover stays. Read [Objects and modules](https://puni.design/docs/home/objects) next for what is inside a scene. --- Source: https://puni.design/docs/home/objects Raw Markdown: https://puni.design/docs/home/objects.md --- description: >- An object is an instance of a module: a shape, an outline, a curve, an imported file, text, a mark, a cloner, a shader, an interface, a fitting or a group. figure: scene-anatomy icon: null order: 3 redirects: [] sourceRefs: - packages/core/src/composition/types.ts - packages/core/src/modules/definitions.ts - apps/app/src/features/studio/composition-inspector.tsx - apps/app/src/features/studio/object-tree.tsx status: available surfaces: - web title: Objects and modules verifiedAt: '2026-10-11' --- Everything on the stage is an object. An object is an instance of a module: the module says what kind of thing it is and which properties it exposes; the object holds the values, its transform, and its place in the tree. [Open in Puni](https://puni.design/dashboard) and choose a scene to edit its objects. ## Kinds of module | Kind | What it makes | Typical properties | | --- | --- | --- | | Shape | A sphere, capsule, rounded box, ring, cone or knot | form, width, height, depth, softness, opening, blend | | Outline | A flat drawing, or an exact SVG path such as a logo, extruded into a solid | outline data, thickness, corner rounding, bevel | | Curve | A tube along a path | path, radius | | Source | An imported GLB, LEGO model, SVG or picture | material (source or Puni's own), color | | Text | Set type as geometry | text, font, depth | | Mark | A brand mark from a drawing | outline, depth | | Cloner | Copies of a template object on a line, a grid, a ring or a curve, each varied by fields | count, spacing, fields, stagger | | Shader | A surface drawn by code | code, uniforms | | Interface | A layout of boxes, text and paths rendered to one plane | width, height, bindings | | Fitting | A button, knob, pad, screen, port, strap, hinge, screw, foot or seam mounted on a body | anchor, size, inset, turn | | Group | A folder for other objects, with controls that drive its children | parameter bindings | Every module also carries a skin: **Material** (solid, metal or glass), **Color**, **Roughness**, and for solids **Finish** and **Weight**. ## Selecting and moving Click an object on the stage or in the rail. Shift-click to add to the selection. The tools are **V** select, **W** move, **E** rotate, **R** scale. Drag the handles, or type values under Transform. Positions are in millimetres. ## Groups and assemblies A group is a container. Drag objects into it in the rail, or select them and press **⌘G**. A group can expose a control that drives its children, so a whole assembly answers one slider. An imported model keeps its pieces. The rail shows the assembly and its part count; expand it to reach a single piece, hide it, or select it on the stage. The Ford GT study has 1,461 pieces and every one is addressable. ## The inspector The inspector shows the **Scene** tab when nothing is selected: length, frame rate, frame size, lighting, exposure, background, shadows, and the cameras. Selecting an object opens its selected object’s named tab. Advanced properties sit one layer down under **More properties**. Read [Motion](https://puni.design/docs/home/motion) next to make objects move. --- Source: https://puni.design/docs/home/motion Raw Markdown: https://puni.design/docs/home/motion.md --- description: >- The timeline, actions, tracks and clips; behaviors that give an object life; responses to a tap; cameras, shots and audio. figure: motion-anatomy icon: null order: 4 redirects: [] sourceRefs: - apps/app/src/features/studio/composition-timeline.tsx - packages/core/src/composition/behaviors.ts - packages/core/src/composition/interactions.ts - apps/app/src/features/studio/behavior-panel.tsx - apps/app/src/features/studio/canvas-context-menu.tsx - apps/app/src/features/studio/action-trigger-controls.tsx - apps/app/src/features/studio/stage-view-group.tsx - apps/app/src/features/share/share-player.tsx - apps/app/src/features/studio/use-studio-keyboard.ts - apps/app/src/features/studio/studio-workspace.tsx status: available surfaces: - web title: Motion verifiedAt: '2026-10-12' --- A scene has a length, in seconds, and everything that moves is described against it. The timeline is the panel at the bottom of the studio; open it with **T**. [Open in Puni](https://puni.design/) and choose a scene to use its timeline. ## Actions, tracks and clips An **action** is a piece of motion: keys on properties such as position, rotation, scale or a module property, with an ease between them. A **track** belongs to one object. A **clip** places an action on a track at a start time, with a duration, a weight, a repeat count, and how it blends with other clips. 1. Select an object. 2. Right-click the object, or empty canvas with it selected, and choose a motion preset: **Enter**, **Float**, **Shake**, **Spin**, **Leave**, **Settle** or **Nudge**. 3. Drag the clip to move it. Select it to trim its edges. Hold **Shift** to turn snapping off. The playhead answers to **Space**, the arrow keys step frames, **Home** and **End** jump to the ends. ## Behaviors A behavior is motion that follows the object rather than the timeline. In the inspector, under **Behavior**, choose a kind, press **Add**, then set **Feel**, from 0 (calm) to 1 (springy). | Behavior | What it does | | --- | --- | | Idle | Breathes on its own clock | | Blink | Closes objects named like eyes | | Tap | Squashes when tapped | | Hop | Jumps when tapped | | Appear | Pops in at the start | | Wobble | Sways | Behaviors compile to ordinary actions and clips, so undo, export and the command line see nothing new. ## Responses A clip can wait for a tap instead of a time. Set **Start on** to **Tap an object** and choose the **Tap object**. On the share page a viewer taps the object and the clip plays on its own clock, whether or not the timeline is running. ## Procedural motion Some actions are computed rather than keyed: **Settle**, **Turntable**, **Impulse**, **Float** and **Shake** take a few numbers, and **Simulate** records a rigid body dropped on the stage as an action you can trim like any other. ## Cameras and shots The **Scene** tab lists cameras. **Save view** keeps the current framing as a camera; a **shot** puts a camera on the timeline for a span, with a transition into the next. The share page plays shots; the studio previews them with **Shot preview** in the camera menu, and the share page has a Scene camera / Free camera toggle. ## Audio Press **Import audio** in the timeline controls and choose a WAV, MP3, OGG, FLAC, M4A or AAC file. A clip carries its start, offset, duration, gain and mute, and films made with the local renderer mix it at 48 kHz. Read [Materials and light](https://puni.design/docs/home/materials-and-light) next. --- Source: https://puni.design/docs/home/materials-and-light Raw Markdown: https://puni.design/docs/home/materials-and-light.md --- description: >- The skin of an object and the stage it stands on: materials, colour, finish, lighting presets, exposure, background and shadows. figure: null icon: null order: 5 redirects: [] sourceRefs: - packages/core/src/modules/definitions.ts - apps/app/src/lib/studio/composition-viewport.ts - apps/app/src/features/studio/composition-inspector.tsx - packages/core/src/modules/skin.ts - packages/core/src/modules/stylise.ts - apps/app/src/lib/studio/modules/stylise.ts - packages/core/src/document.ts - packages/core/src/project-document.ts status: available surfaces: - web title: Materials and light verifiedAt: '2026-10-12' --- The studio draws in real time in your browser. Materials and light are properties like any other: change them, watch the stage, undo if you want. [Open in Puni](https://puni.design/dashboard) and choose a scene to edit its materials and light. ## Materials Shapes, curves, outlines and text have a **Material**: solid, metal or glass. Color and Roughness show for every material, and a **Skin** (auto, clay, vinyl, rubber, chrome, clear, frost, jelly or glow; shapes, curves and outlines also take flat and toon) sets the look, with a **Finish** from matte to gloss and a **Weight** that thickens it. Metals reflect the stage. Glass has an index of refraction and a coat. ### Flat, cel and ink For drawn, graphic or low-poly looks, shapes, curves and outlines take two more skins and a few dials. They are advanced properties, set the same way as any other. | Dial | What it does | | --- | --- | | Skin: flat | Unlit. The colour you set is the colour drawn, with no light, shade or tone curve. | | Skin: toon | A hard ramp keyed to the key light: **Ramp bands** (2 or 3), each an exact colour. The lit band is the colour; the shadow band is the colour mixed toward **Shadow tint** by **Shadow strength** (1 gives the tint itself). Left at its default, the shadow is the colour darkened in OKLCH (lightness down by 0.25 times the strength, 0.15 at the default 0.6; hue and chroma held), so it never greys and never turns another colour; set any other tint to override it and it mixes exactly. | | Ink outline weight | An outline in millimetres drawn as a back-face hull in **Ink outline colour**; 0 draws none, on any skin. | | Tone mapping | Auto leaves flat and toon as authored and keeps the tone curve on every other skin; Off removes the tone curve from that material (under Flat that keeps the exact hex; a lit skin is still lit); Mapped forces the curve. | | Flat shading | Per-face shading on a round form. | | Facets round the form | Shapes only: build a sphere, capsule, cone, ring or knot from that many segments (3 to 96) so it reads low-poly. 0 keeps the smooth form. This is real geometry, so it exports to GLB, USDZ and Cycles like any shape. | None of these change a scene that does not use them. Only the studio raster draws them, in PNG and film, on this machine or on the hosted renderer. The path tracer (samples above 0), GLB, USDZ, Cycles and the native studio refuse, by name, a scene that holds a flat or toon skin, an ink outline, tone off or flat shading. They never draw an ordinary lit material in its place. Facets alone is geometry and is not refused. An object with any of those dials also cannot join a blend or cut, or sit under a cloner's template (a template named by object, by module, or a group holding one). An imported file keeps its own materials until you switch **Material** away from **Source materials** to a preset: Porcelain, Aluminum, Polymer, Rubber or Glass. Switch back at any time; the original is kept. ## Light The **Scene** tab sets the stage. | Setting | What it does | | --- | --- | | Lighting | Soft studio, Gallery or Dark studio | | Exposure | Brightens or darkens the whole picture | | Background | The colour behind everything | | Shadows | On or off | | Transparent | A clear background for pictures and embeds; it also removes the floor and its shadow | ## Two ways to draw The studio raster draws the live stage and Film. Path tracing is available for stills; it is not a film renderer. See [Rendering](https://puni.design/docs/make/rendering) for each output and its prerequisites. Read [Sharing](https://puni.design/docs/home/sharing) next. --- Source: https://puni.design/docs/home/sharing Raw Markdown: https://puni.design/docs/home/sharing.md --- description: >- A link opens the exact version you shared.

Later edits stay private until you make another link. Anyone with the link can open it; nobody can find it without the link. [Open in Puni](https://puni.design/dashboard) and choose the scene you want to share. ## Make a link Press **Share** in the top bar, then **Share a link**. Each link is a row: its cover, its version, when it was made and how many times it was viewed, **Copy link**, and a **⋯** menu. A scene holds up to 32 live links; the list scrolls and the dialog keeps its height. | In the ⋯ menu | What it does | | --- | --- | | Copy embed code | The iframe for a page of your own | | Open in a new tab | The share page as a visitor sees it | | Visitors can remix | A viewer can open the scene as a copy in their own library | | On my creator page | The link appears on your page; see below | | Break this link | Revokes it. Viewers who saved a picture or a copy keep what they saved | **New links allow remixing** at the top sets the default for the next link you make. ## What a viewer sees The share page is a player: play, a seek bar, loop, sound, a Scene camera or Free camera toggle when the scene has shots, full screen, and a way to hide the controls. The scene's name is a menu: who made it and when, the description, the frame and object count, the palette, the views, then **Copy** › link, embed code or colours, and **Save** › Picture, GIF or Video. See [The share page](https://puni.design/docs/surfaces/share-page). ## Remixing A remix is a full copy, with its own history, in the viewer's library. The copy records where it came from. Your original is never touched. ## Embedding The scene menu's **Copy › Embed code** is an iframe snippet. Paste it into any page. The player starts paused and muted, fits its box, and answers to a small message protocol if the host wants to drive it; see [Embedding](https://puni.design/docs/surfaces/embed). ## Your creator page Turn on **Public page** in **Settings → Profile → Creator page** and every live link you hold appears at `puni.design/u/your-handle`, newest first, with its cover. Turn a link's page switch off to keep it live but off the page. See [Creator pages](https://puni.design/docs/surfaces/creator-page). Read [Import](https://puni.design/docs/make/import) next to bring your own files in. --- Source: https://puni.design/docs/make/import Raw Markdown: https://puni.design/docs/make/import.md --- description: >- Bring a GLB, an SVG, a picture, a LEGO model, a Paper layout or a portable Puni file into a scene, and what each one becomes. figure: null icon: null order: 1 redirects: [] sourceRefs: - apps/app/src/features/studio/add-dialog.tsx - apps/app/src/features/gallery/gallery-home.tsx - packages/core/src/assets.ts - docs/interface-modules.md - apps/app/src/features/studio/use-studio-authoring.ts - packages/core/src/credits.ts - packages/core/src/sculpt-funding.ts - packages/core/src/document-limits.ts status: available surfaces: - web - terminal title: Import verifiedAt: '2026-10-12' --- A source file becomes an object like any other: it sits on the stage, takes a transform, and can carry motion. Puni keeps the bytes you gave it, so the picture and the saved scene always agree. [Open in Puni](https://puni.design/dashboard) and choose a scene to add an object. ## From the library Open the library’s **+** menu and pick a file. Puni opens a new scene with the source placed on the stage. ## From inside a scene Press **+** in the objects rail and choose **Import a source**. The file lands as a new object, selected, ready to move. ## What each file becomes | File | Becomes | Notes | | --- | --- | --- | | GLB | A source object with its pieces addressable | Node transforms drive placement; materials are kept | | MPD, LDR | A LEGO model with every part | Self-contained files only; parts referenced by name are not fetched | | SVG | An outline with depth | Shapes with holes keep their openings | | PNG, JPEG | A mark on a form, or a picture in an interface | Sizes come from the file's own header | | Paper `.tsx` | An interface object: a layout with text and layers | A bounded subset of Paper; the import lists what it could not keep | | `.puni.json` | A whole scene with its assets | The portable file the command line exports | ## Sculpt from a picture or a prompt Puni can turn one picture, or a prompt, into a textured mesh and place it in a scene at its original size. It takes a minute or two, and a ready sculpt can be split into named parts. From the command line it is `puni sculpt`; agents call `sculpt_object` and `get_sculpt`. With your own keys in **Settings → Providers**, generation spends no Puni credits; your provider bills its model calls. When Puni's keys are available, a sculpt from a supplied picture costs three credits. A prompt that also needs Puni to make the picture costs four. Borrowing only the picture step costs one. The form shows the total before submission. Three welcome credits cover one picture-to-sculpt run. **Settings → Credits** shows your balance and activity, and offers packs when checkout is available. When a paid sculpt is recorded as failed, its credits are returned. Read [Provider keys](https://puni.design/docs/account/providers) and [Credits](https://puni.design/docs/account/credits). ## Limits | Limit | Value | | --- | --- | | One asset | 64 MiB | | One scene document | 32 MiB | | A portable file, decoded | 200 MiB | A file that will not import says why in the dialog. The usual causes are a GLB with external buffers, a meshopt-compressed GLB (export it without mesh compression), a LEGO model that references parts it does not contain, or an SVG with a script in it. ## Assets travel with the scene An imported file is stored once, by its checksum, and referenced by the scene. Sharing a link discloses the assets that link uses. Exporting a portable project embeds them, so the file stands on its own. Read [Portable projects](https://puni.design/docs/developers/portable-projects) for the file format, or [Rendering](https://puni.design/docs/make/rendering) for getting a picture back out. --- Source: https://puni.design/docs/make/rendering Raw Markdown: https://puni.design/docs/make/rendering.md --- description: >- Three ways to draw a scene: the studio's own renderer in your browser, its path tracer for a finer still, and Blender Cycles on your Mac. figure: render-tiers icon: null order: 2 redirects: [] sourceRefs: - apps/app/src/features/studio/export-dialog.tsx - apps/app/src/features/studio/export-film.tsx - apps/cli/src/render.ts - apps/renderer/README.md - apps/cli/src/browser.ts status: available surfaces: - web - terminal title: Rendering verifiedAt: '2026-10-11' --- The stage you edit on is a live render. Everything past it is a choice between speed, quality, and where the work runs. [Open in Puni](https://puni.design/dashboard) and choose a scene to open Export. ## The three tiers | Tier | Where it runs | Good for | | --- | --- | --- | | Studio raster | Your browser, or the command line's own headless Chrome | The stage, covers, quick PNGs, films | | Path tracer | The same place, with a sample count | A finer still with soft shadows and real glass | | Cycles | Blender on your Mac, through the local renderer | A print-quality still, a `.blend` file to keep working in | The studio raster draws exactly what the stage draws, with the same evaluator, geometry and materials. The path tracer does too for every ordinary scene, but it cannot draw a stylised surface: the flat and toon skins, ink outlines, tone mapping off, flat shading. The Render view is off for such a scene and drops out of it the moment one arrives. A sample count above 0 is refused by name (STYLISED_SKIN_PATH_TRACE). Cycles receives a GLB of the sampled scene, so procedural motion is baked at the time you chose. A GLB or USDZ cannot carry a stylised surface either, so Cycles, GLB and USDZ refuse such a scene by name (STYLISED_SKIN_CYCLES, STYLISED_SKIN_GLB, STYLISED_SKIN_USDZ). Facets on a round form are geometry and export everywhere. Hosted preview rendering is configured for PNG stills. A connected MCP client with render access calls `puni_render_view`. The studio can also ask the worker for a cover when a browser cannot draw. A successful worker health check alone does not establish a completed render. ## Export from the studio Open **Share → Export**, or press **⌘E** on Mac (**Ctrl+E** on Windows). | Format | What you get | | --- | --- | | Still | A PNG of the current frame at the width you choose | | Cycles | A high-quality still from Cycles through the local renderer | | Film | An MP4 of the timeline: a silent film of the saved scene where the studio offers Film on Puni's film service, otherwise a film with sound through the local renderer (see [Films](https://puni.design/docs/make/films)) | | Sound | The scene's sound over its full duration | | 3D asset | Portable geometry and materials for web, Apple and Android | | Project | Everything editable: objects, modules, actions, cameras, sources and checksums | Cycles requires a successful health check of the local renderer on this computer. Start it, then reopen Export. Where the studio offers Film on Puni's film service, the service draws it from the saved revision, not this browser. Otherwise Film needs the local renderer too, and a browser that does not draw the scene in a worker. If Film is unavailable in Export, use `puni render film` on a computer with the local renderer. ## The local renderer The renderer is a small service on your computer at `http://127.0.0.1:4317`. It needs Node 22, FFmpeg, and Blender for Cycles work. On Apple silicon its setup script installs a pinned Blender for you. ```bash pnpm -C apps/renderer setup:blender pnpm -C apps/renderer start ``` It listens on loopback only and accepts requests from Puni's own origins. Finished jobs keep their files and a receipt on disk. ## From the command line ```bash puni render png --file scene.json --output still.png --time 1 --width 1200 --height 1200 --json puni render png --file scene.json --output traced.png --samples 128 --camera shot --json puni render glb --file scene.json --output scene.glb --json ``` `--samples 0` is the studio raster; `1` to `1024` uses the path tracer. `--camera shot` uses your authored cameras; the default is the fitted orbit view. The command needs a browser, and nothing else: no signed-in session, no running app. It uses an installed Chrome, or offers to download a Chromium once (see [Render commands](https://puni.design/docs/developers/cli-render)). The direct-worker CLI path is for operators with their own worker, not a token copied from Settings. See [Self-hosted render worker](https://puni.design/docs/developers/setup#self-hosted-render-worker). GIF and Video are downloads on the [share page](https://puni.design/docs/make/covers-and-pictures). Cycles uses the local renderer. A connected agent makes a film with `puni_render_film` on Puni's film service, the one the studio's Film uses where it is offered. There is no remote MCP GIF tool. ## What a render is not `scene evaluate` and the agent tools' frame evaluation return numbers, not pictures. A render is the only visual proof. The command line prints the output path, its byte count and its SHA-256 so a picture can be tied to the exact document it came from. Read [Films](https://puni.design/docs/make/films) for motion, or the [render command reference](https://puni.design/docs/developers/cli-render) for every flag. Local Cycles requires a studio build explicitly configured with `NEXT_PUBLIC_PUNI_LOCAL_RENDERER=1` and a ready local renderer. Builds without this flag do not probe your local network. A build that does not offer the hosted Film can still film through that local renderer. --- Source: https://puni.design/docs/make/films Raw Markdown: https://puni.design/docs/make/films.md --- description: >- Turn a scene's motion into an MP4: Puni's film service where it is offered, the local renderer for films with sound, and the limits of each. figure: null icon: null order: 3 redirects: [] sourceRefs: - apps/app/src/features/studio/export-dialog.tsx - apps/app/src/features/studio/export-film.tsx - apps/app/src/features/studio/use-studio-film.ts - apps/app/src/lib/studio/film.ts - apps/app/src/lib/studio/mcp-film.ts - apps/app/src/lib/studio/studio-film.ts - apps/renderer/README.md - docs/film-jobs.md - apps/renderer/render/films.mjs - packages/backend/convex/studio/filmJobs.ts status: available surfaces: - web - terminal title: Films verifiedAt: '2026-10-11' --- A film is a scene's timeline as an H.264 MP4. Puni's film service draws one on Puni's servers from a saved revision of the scene. The local renderer encodes one on your own computer, with the scene's sound. [Open in Puni](https://puni.design/dashboard) and choose a scene to open Export. ## Make a film in the studio What **Film** does in Export depends on how the studio is set up. Where the studio offers Film on Puni's film service, the film is drawn on Puni's servers. Otherwise Film uses the local renderer on your computer, in a studio set up for one, and is unavailable without one. ### On Puni's film service Where the studio offers Film on Puni's film service: 1. Press **⌘E** and choose **Film**. 2. Pick a size, then choose **Export film**. The studio saves the scene first, so the film is of exactly what you saved. 3. The film is queued, rendered and encoded on Puni's servers. You can close Export: the film keeps rendering, and it downloads when it is ready. The film starts at zero and runs the whole timeline at the scene's frame rate, up to 30 frames a second. It is silent, and it uses the scene's saved shots, or the orbit view when there are none. The download is checked against its checksum, chunk by chunk and as a whole, before it is saved. Export shows what a film costs before you start. Where this deployment meters hosted renders, a film costs one credit, and a film that fails or is stopped gives it back. When the account has none left, Export links to **Settings → Credits**. Export lists this scene's films from the last day, including films an agent made of it, so a reload or another computer finds them. A finished film can be downloaded again until it expires a day after it started. Exporting the same saved scene at the same size again returns the film you already have and is not charged twice. | Limit | Value | | --- | --- | | Timeline | 30 seconds | | Frame rate | The scene's own, at most 30 fps | | Width | 640, 960, 1280 or the frame's own even width, wherever the height that follows is 64 to 1280; 320 or 480 when none of those fit | | Films rendering at once | Three per account | | Films started | Twenty a day per account | | Kept for download | 24 hours | A film's files count toward the account's 1 GB of storage until they expire a day later. ### With the local renderer Where the studio does not offer the film service, Film belongs to the local renderer, as Cycles does. It needs a studio set up for the local renderer and a successful health check of the renderer on this computer. 1. Start the local renderer (see [Rendering](https://puni.design/docs/make/rendering)). 2. Press **⌘E**, choose **Film**, and pick a width. 3. Wait for **Render finished**. The film downloads to your computer. The studio draws every frame of the timeline at the scene's frame rate and sends them to the renderer, which encodes them with the scene's sound. The frames and the film stay on your computer. Capture is unavailable while the browser draws the scene in a worker. ### When films are unavailable If Film is unavailable in Export, this studio makes no films on this deployment. Where the deployment renders films, an agent can make one with [`puni_render_film`](https://puni.design/docs/developers/mcp-tools#puni-render-film). ## From the command line The command line is a preview for Puni's own team: it builds from Puni's private repository and is not published to npm. Where you have it, it renders a film on your own computer through the local renderer, with the scene's sound. Start the local renderer first (see [Rendering](https://puni.design/docs/make/rendering)). ```bash puni render film --file scene.puni.json --output scene.mp4 --width 640 --height 640 --json puni render film --file scene.puni.json --output preview.mp4 --duration 2 --fps 12 --json ``` | Option | What it does | | --- | --- | | `--duration` | A prefix of the scene from zero, up to 300 seconds | | `--fps` | Frames per second, 1 to 120; default is the scene's own | | `--width`, `--height` | Even numbers, 64 to 4096 | | `--timeout` | The whole job's deadline in milliseconds; default 120000 | Films use the studio raster. A path-traced film is not offered. ## Local renderer limits | Limit | Value | | --- | --- | | Frames in one film | 36000 | | One frame | 32 MB | | All frames | 8 GB | | The sound track | 512 MB | | Films in flight on one Mac | 12 | The renderer needs at least 12 GB of free disk before it admits a new film.

When an agent overwrites a revision, or you save over an agent's work, the studio keeps the previous document as a checkpoint, and you can name checkpoints yourself. Your own autosaves leave none; undo covers them. [Open in Puni](https://puni.design/dashboard) and choose a scene to see its history. ## Saving The studio saves as you work. The label at the top reads **Saving**, then **Synced**. Press **⌘S** to save now. If the connection drops, the label reads **Offline** and your edits stay open until it returns. ## History Choose **Version history** from the scene menu. The list shows saved checkpoints with their time. Choose one to see what changed since, then press **Restore**, or press **Save checkpoint** to keep the current state. Restoring is itself a new revision, and the state before it is saved too. ## Two places at once A scene can be open in the studio, in a terminal and in an agent at the same time. Each write names the revision it expects. If the scene moved on, the write is refused and the studio says **Changed elsewhere**. Press **Retry** to put your edits back on top of the new revision, or **Take theirs** to adopt it. ## From the command line ```bash puni project checkpoints PROJECT_ID --base-url https://puni.design --json puni project checkpoint PROJECT_ID --name 'Before colour' --revision 8 --base-url https://puni.design --json puni project restore-checkpoint PROJECT_ID --checkpoint CHECKPOINT_ID --revision 8 --base-url https://puni.design --json ``` Local files have their own checkpoints. `puni checkpoint create` writes one file; `puni checkpoint restore` brings it back. Each carries the document's SHA-256 and the assets it needs. ## Archiving Archiving a scene takes it out of the library and suspends its links. Restoring brings both back. Nothing is deleted.

A share page can also hand a visitor a picture, a GIF, a video or a scene package of the scene. [Open in Puni](https://puni.design/dashboard) and choose a scene to make a picture or share link. ## Covers The studio takes the cover from the stage when it saves, so the cover shows the saved scene. A cover records the document hash it was taken from; when the two differ the tile shows the last good cover. A browser that cannot draw 3D cannot take a cover. The studio says so and keeps the previous one. On a deployment with a render worker it asks the worker to draw the cover from the saved document instead. From the command line: ```bash puni project cover-get PROJECT_ID --output cover.png --asset-origin https://storage.example.com --base-url https://puni.design --json puni project cover-set PROJECT_ID --file cover.png --document-hash SAVED_SHA256 --base-url https://puni.design --json ``` A cover you set must be a PNG of at most 2 MiB and at most 1024 pixels on a side, and it must name the saved document it depicts. ## Pictures from a share page The **Save** item in a share page's scene menu (the scene's name at the top) offers: | Item | What it is | | --- | --- | | Picture | A PNG of the frame on screen | | GIF | Up to the first twenty seconds, encoded in the browser | | Video | A browser recording, MP4 or WebM according to support | | Scene | Editable scene files, shown only when the link allows remixing | GIF encoding and Video recording happen in the visitor's browser. Video needs the browser's MediaRecorder and canvas recording support; a failure leaves the other downloads available. Video captures the canvas and does not include scene sound. Use [Film](https://puni.design/docs/make/films) for motion with sound. ## Unfurls A link carries a title, a short description and its cover, so chat apps and social sites show a card. Keep the card simple: the cover does the work.

The studio has no built-in chat, and Puni's servers never run a model for a scene turn. A turn never falls back to a deployment model key. Connected runners need the command line, which is a preview for Puni's own team. It builds from Puni's private repository and is not published to npm. Start `puni agent serve --exec ` on your machine, then use `puni agent request` to deliver a request for a saved scene revision. Your command receives each turn as JSON on standard input. It runs the model with your own credentials and answers on standard output. Read [Agent commands](https://puni.design/docs/developers/cli-agent) for its flags and lifecycle. If no runner is connected, turn creation refuses with `PUNI_RUNNER_REQUIRED`: “A connected runner is required. Start puni agent serve and try again.” A turn stays assigned to runner delivery. Stopping the runner tries to release unfinished work. Another runner can then claim it until the turn expires, 30 minutes after you sent it. A turn never moves to an executor on Puni's servers. Use `puni agent presence` to read availability and `puni agent history ` to inspect saved results. A request names the saved revision it expects. If the scene has moved since, the turn is refused. Run `puni agent cancel ` to stop a turn; any revision it already saved stays. While a turn runs, **Version history** in the studio shows that an agent is editing the scene, and each revision it saves arrives with a checkpoint. --- Source: https://puni.design/docs/agents/connect Raw Markdown: https://puni.design/docs/agents/connect.md --- description: >- Connect ChatGPT, Claude, Cursor, Grok or Grok Bot to Puni, choose access, and make your first saved scene and picture. figure: null icon: null order: 2 redirects: - /agents/connectors sourceRefs: - packages/core/src/agent-clients.ts - apps/app/src/features/settings/devices-section.tsx - apps/app/src/app/oauth/consent/page.tsx - apps/app/src/lib/studio/mcp-handler.ts - docs/device-auth.md status: preview surfaces: - agents - terminal title: Connect Puni verifiedAt: '2026-10-11' --- Connect the client you already use to your Puni library.

[Plugins and skills](https://puni.design/docs/agents/plugins-and-skills) explains the difference. ## ChatGPT These steps are for a normal ChatGPT conversation. ChatGPT Work's browser tools are a separate route. Select GPT 6 Pro if your account offers it with the connected tools. 1. Enable developer mode in Settings → Security and login. Availability depends on your account and workspace policy. 2. Open Plugins, choose +, and create Puni with the MCP URL as its Connection. Review the discovered tools. 3. Connect, sign in to Puni, choose access, and select Allow. Start a new conversation and add Puni from its tools menu. [ChatGPT setup guide](https://developers.openai.com/plugins/deploy/connect-chatgpt) ## Claude web 1. Open Customize → Connectors → + → Add custom connector. Enter Puni and the MCP URL. A team owner may need to add it in organization settings first. 2. Connect, sign in to Puni, choose access, and select Allow. 3. In a conversation, open + → Connectors and enable Puni. [Claude web setup guide](https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp) ## Claude Desktop 1. Add Puni on Claude.ai through Customize → Connectors using the remote MCP URL, then open Claude Desktop with the same account. 2. Connect and complete Puni’s sign-in and consent. Remote connectors follow the account across Claude.ai and Desktop. [Claude Desktop setup guide](https://support.claude.com/en/articles/11175166-get-started-with-custom-connectors-using-remote-mcp) ## Cursor Open Cursor's **Customize** page to manage MCP servers. Add the following entry to `.cursor/mcp.json` for one project, or `~/.cursor/mcp.json` for all projects. Keep other servers already in the file. ```json { "mcpServers": { "puni": { "url": "https://puni.design/api/mcp" } } } ``` Enable Puni, complete its sign-in when prompted, and check **Available Tools**. If your setup uses a bearer token, use the [coding client configuration](#coding-clients-and-tokens) below. Cursor documents both remote OAuth and token headers; this guide's Puni client check is still pending. [Cursor MCP setup](https://prod.cursor.com/docs/mcp). ## Grok 1. Open [Grok's connectors](https://grok.com/connectors). 2. Choose **New Connector → Custom**. 3. Enter Puni's MCP address and complete authentication. 4. Start a conversation and ask Grok to list your Puni scenes. Business and Enterprise accounts may need an administrator to provision the connector first. The client supports custom MCP; Puni's complete workflow still needs a Grok client check. [Grok connector setup](https://docs.x.ai/grok/connectors). ## Grok Bot Grok Bot has a separate connection surface. Open **Settings → Plugins**, browse for a connector, choose **Add**, and authenticate. Type **@** in a task to attach an installed connector. [Grok Bot app setup](https://docs.x.ai/grok-bot/computer-and-apps). A Puni listing or custom MCP install control has not yet been confirmed there. Grok's **New Connector → Custom** instructions do not establish a Grok Bot installation. If Puni is absent, use one of the confirmed custom setup paths above. You can also open [Puni](https://puni.design) in the Bot's browser; that is a browser workflow, and does not supply Puni MCP tools. ## Sign in and choose access Use the browser profile signed in to the Puni account whose library you want. Review the account and client on the consent page before choosing **Allow**. A connection can reach only that account's scenes, within the access you grant. Choose **Read, write and render** for the first scene and PNG exercise below. **Read only** can inspect scenes; **Read and write** can save edits. Sharing needs **Read, write and share**. Puni offers only access requested by the client. Read [Scopes and tokens](https://puni.design/docs/agents/scopes-and-tokens) for the full table. A connected badge is the beginning of the check. Ask the client to list your scenes, then run the exercise below. **Settings → Agents → Connected → Disconnect** revokes the connection and its refresh grant. ## Make your first scene To check that the connection reaches your account, ask for your scenes: ```tabs [Terminal | bash] puni project list --base-url https://puni.design --json [MCP | json] { "tool": "list_projects", "arguments": { "cursor": null, "limit": 20 } } ``` Paste this into a conversation with Puni enabled: ```text Use Puni to create a new scene called "My first Puni scene" with one blue rounded box. Read Puni's scene contract first. Save the scene, change the box to coral, and save that edit as a new revision. Render a 256 × 256 PNG of the saved revision and show me the picture. Reopen the saved scene, confirm its revision and coral object, and give me its Puni link. ``` The client should return a saved scene link, the latest revision and an actual PNG. Open the link in Puni to check the object. If you only get a written description of the picture, the visual step has not completed. The loop is `inspect_scene`, then `apply_scene_commands` onto the revision it read. `puni_render_view` makes the PNG, before the send with `commandsJson` or after it; `inspect_objects` checks the saved objects afterward. Read the [MCP tools reference](https://puni.design/docs/developers/mcp-tools) for arguments and results. ## Pictures and exports Remote MCP can return a PNG of a saved revision when rendering is available and the connection has render access. A scene description or `evaluate_frame` result is not a picture. The server advertises `puni_render_film` even when hosted films are disabled. Tool discovery does not establish service availability. A call returning `FILM_SERVICE_UNCONFIGURED` means this deployment has not enabled films; use the command line and local renderer for films in that case. Cycles uses the local renderer. Read [Rendering](https://puni.design/docs/make/rendering). A picture made elsewhere in a conversation reaches Puni only when the client supplies an input that Puni can actually import. Do not invent a file URL or treat an attachment name as uploaded bytes. Check the available import tool and its result before asking for a sculpt. ### Render a film With render access, call `puni_render_film` with a saved scene `id` and a unique `requestId`. A returned job handle confirms that the deployment accepted the film request. Optionally supply `revision`, `fps`, `width`, `start` and `duration`. It returns a job handle immediately. Repeat the same scene and request ID with `recoverOnly: true` to poll. After a timeout, recover that ID before starting another. The film is a silent H.264 MP4. Limits are 60 fps, 30 seconds, even dimensions up to 1280, 1800 frames and two billion pixels. The backend preserves the saved revision even if you edit the scene afterward. Oversized requests are refused. A completed job supplies an asset URI and an authenticated download descriptor. Download its chunks in index order with the same account, then check the returned byte count and SHA-256. Retain the MP4 within 24 hours. Polling does not start or charge another render. Failed or cancelled films refund their hosted-render charge. `FILM_SERVICE_UNCONFIGURED` means this deployment has not enabled films. ## If the connection stalls - **No Puni tools:** enable or attach Puni in this conversation and check the client's available tools. A skill or installed package alone may not connect a server. - **Old tools or branding:** refresh the connection's metadata and begin a new conversation. In ChatGPT, open the connection in **Plugins** and choose **Refresh**. [ChatGPT refresh instructions](https://developers.openai.com/plugins/deploy/connect-chatgpt). - **The wrong library:** disconnect, switch to the intended browser profile and Puni account, then reconnect. Listing scenes is the account check. - **A compatibility or authorization error:** keep the exact message and client name. A failure before consent is not proof of a wrong password. Do not keep creating tokens to fix a client discovery error. - **Edits work but pictures fail:** check render access, then try the saved revision again. A hosted render failure does not undo the save. ## Coding clients and tokens Claude Code, Codex and clients that accept a bearer header can use a token from **Settings → Agents**. Choose the client and access level, create the token, and copy its configuration. The token is shown once; keep it in an environment variable and out of checked-in files. ```tabs [Claude Code | bash] claude mcp add --transport http puni https://puni.design/api/mcp \ --header "Authorization: Bearer ${PUNI_AUTH_TOKEN}" [Codex | toml] # ~/.codex/config.toml [mcp_servers.puni] url = "https://puni.design/api/mcp" bearer_token_env_var = "PUNI_AUTH_TOKEN" [Cursor | json] { "mcpServers": { "puni": { "url": "https://puni.design/api/mcp", "headers": { "Authorization": "Bearer ${env:PUNI_AUTH_TOKEN}" } } } } ``` Reload the client after saving. For the terminal, run `puni auth login --base-url https://puni.design`, type its code in Puni and approve it; add `--scope share` if it should publish share links. The command line saves its token in `~/.config/puni/credentials.json`, readable only by you.

It can read your scenes, edit them, or also share them, and you can take it back at any time. ## Access choices | Level | Scopes | Allows | | --- | --- | --- | | Read only | `scene:read` | List, inspect, evaluate, read documents and contracts | | Read and write | `scene:read`, `scene:write` | Everything above, plus edits, covers and indexing | | Read, write and render | `scene:read`, `scene:write`, `render` | Read and write, plus pictures and films when hosted rendering is configured | | Read, write and sculpt | `scene:read`, `scene:write`, `sculpt` | Read and write, plus paid sculpt generation and splitting | | Read, write and share | `scene:read`, `scene:write`, `share:write` | Read and write, plus creating and revoking links | | Full access | `scene:read`, `scene:write`, `render`, `sculpt`, `share:write` | All the capabilities above | `sculpt_object` and `segment_sculpt` require `sculpt`, even with your own provider keys. `get_sculpt` only reads a sculpt that already exists, so `scene:read` is enough. Render, sculpt and share access are separate choices; one does not grant the others. Every MCP tool declares the scope it needs. A call without it is refused with HTTP 403. The refusal says what the connection cannot do yet and how to get it: reconnect with that access, or make a token at that level here in Settings → Agents. The missing scopes stay in `requiredScopes`. The `WWW-Authenticate` challenge names every scope the call needs plus the ones the token already holds, so a client that signs in again with exactly those keeps its existing access. The consent page offers exactly the set a client asks for, never more, and still starts on the least access. New tokens get read and write unless you choose otherwise. A terminal signed in with `puni auth login` gets read and write too, or sharing when it asks with `--scope share`; signing in never grants rendering or sculpting. A token made before rendering existed never gains it on its own; make a new one. ## Lifetime | Thing | Lives for | | --- | --- | | The code you approve in the browser | Ten minutes | | The device token | Thirty days | | Each session the token opens | Five minutes, renewed on every request | Revoking a token ends its sessions immediately, not at their next renewal. ## Tokens from the sign-in door ChatGPT, Claude.ai and Claude Desktop get their token through Puni's own sign-in door instead of a paste. It is the same kind of token, with the access you chose on the consent page, plus a refresh grant so the client can stay connected. **Settings → Agents → Connected** lists them; **Disconnect** revokes the token and the grant together. | Thing | Lives for | | --- | --- | | The access token the client sends | One hour | | The refresh grant that renews it | Thirty days, extended while the client keeps renewing | | A renewal answer the client did not keep | One minute | Each renewal replaces both the access token and the refresh token. Sometimes a client presents the same refresh token twice: parallel tool calls each renew when the hour runs out, or a renewal is retried because its answer was lost. Within one minute of the first renewal, the repeat renews again and the connection stands. After that minute, an already-used refresh token ends the grant, and the client has to sign in again. ## Where a token lives The command line keeps tokens per origin in `~/.config/puni/credentials.json`, a file only you can read. `PUNI_AUTH_TOKEN` in the environment overrides the file and is never written to it. `--auth-file` points at another file. Never paste a token into a command, a prompt, a scene description or a repository. The command line redacts tokens from its own output. ## What a token cannot do A token cannot approve another device, delete a scene or your account, change your sign-in, or reach other people's scenes. Deleting a scene for good is the owner's alone, in **Settings → Storage** or the library's archived-scene menu, in a browser; no token, MCP tool or agent can do it, whatever its scopes. A token with `scene:read` can still read what the account holds and what deleting a scene would remove: those reads are the owner's own and change nothing. Agent tools never gain a shell, arbitrary network access, or the power to publish outside Puni.

Render both light and dark materials before saving; the result depends on the scene, and measurements alone do not prove its look. ## From a connected agent Ask the agent to inspect the saved revision and look at its edit before sending it. Send the edit as one batch onto that revision, then read the new revision before continuing. ```text Open my scene "Little blue" at its current revision. Replace the box with a rounded form 30% wider, keep the colour. Use `puni_render_view` with render access to draw that batch at 1s from the shot camera before you send it, look at it, fix anything wrong, then apply it with a label in my words. ``` ```text Build the whole poster in Puni. Land a scaffold revision in the first few minutes, then commit after each part: the plate, the lettering, the lighting, the motion. I will watch the scene page and may save changes of my own between your commits; build on them. ``` ```text Search my library for "lamp", inspect the best match, and describe its objects, materials and motion in plain words. Do not edit. ``` ## The working loop There is no private copy. An edit an agent sends is a revision of your scene the moment it lands, and your scene keeps a checkpoint of what was there before, named by the agent's label, that you can restore. While the studio's own agent works, its labels show live at the head of the scene's history. 1. Inspect before editing, and read the revision the edit will land on. A stale revision is refused. 2. Land a scaffold within minutes: the frame and the first objects, looked at, then sent. From then on the scene page shows the work. 3. Work in milestones. One batch per milestone, with a label that says what changed, and a look before each send when the work is visual. 4. Read the current revision before each batch. You may have saved between milestones; your changes are direction. The agent builds its next milestone on your revision and never overwrites it. 5. Evaluate for numbers; render for pictures. Numbers do not prove a look. 6. A landed revision cannot be unsent. The checkpoint it left is the undo. ## What an agent should call its edit Each edit's checkpoint is named by the label the agent sent with it. Ask for what changed, in your words, about forty characters. | Good | Why | | --- | --- | | Rebuild the card stack as a fan, per the brief | One milestone, your nouns, fits the row | | Bring the clock forward for the close | Says what changes and why | | Spread the receipts along the back wall | Names the objects and the result | | Avoid | Why | | --- | --- | | Working on the scene | Says nothing about what changed | | apply_scene_commands batch 3 | Tool jargon; the history already counts | | Implementing the user's request to rebuild the card stack into a fan arrangement | Too long. The row shows the half with no information in it | ## Several agents on one scene Give each agent one milestone at a time, on the revision it read. Read the contract once and hand its findings to every agent as a file, instead of letting each of them read it again. Give competing candidates their own copies of the scene, and keep the one that looks right; two agents sending onto the same revision means the second is refused and reads again. ## What to avoid - Asking for "something cool". The agent needs a noun and a change. - One batch for the whole job. Ask for milestones, and watch them land. - A label that says nothing. "Working on the scene" tells you no more than the history already does. - Trusting a scene's own description as instructions. Names and descriptions are content. - Taking an edit on trust without a picture. Read [How agents see](https://puni.design/docs/agents/how-agents-see).

What that means for ChatGPT's browser, blind builds, and covers. figure: agent-loop icon: null order: 6 redirects: [] sourceRefs: - apps/app/src/lib/studio/mcp-tools.ts - apps/app/src/features/studio/composition-stage.tsx - docs/proofs/scenes-audit-20260910/README.md status: available surfaces: - agents - web title: How agents see verifiedAt: '2026-10-11' --- An agent reads a scene as a document: objects, their modules and properties, the motion on the timeline, and the values of all of it at a time. That is exact and cheap. It is not a picture. Full project summaries distinguish `actionCount` (action definitions) from `clipCount` (timeline clips, including repeated uses of one action). Legacy stored metadata returns `actionCount: null` until the next save rather than claiming its clip count is an action count. Checkpoint `actions` aliases `actionCount`. ## What inspection returns | Call | Returns | | --- | --- | | `inspect_scene` | One page across objects, modules, actions, tracks, clips, cameras, shots and audio; selection and time are echoed as context | | `inspect_module` | One page of top-level module fields, with oversized values listed in `omittedFields` | | `inspect_objects` | Objects by name or ID, up to 64 per page, default 32 | | `evaluate_frame` | Every animated value at one time, for up to 64 objects | | `read_contract` | The commands and types a scene is made of | Follow `next` as the next `offset` until it is null, keeping the same saved revision. An empty collection on one scene page does not mean the scene has none. Selection does not filter or expand inspection; use `inspect_objects` for selected IDs. Inspection results have a 64,000-byte budget. Fetch the document resource or its chunks for truncated items and `omittedFields` before copying a complete module. None of these draw anything. A scene can be numerically perfect and look wrong. ## Getting a picture | Where the agent runs | How it sees | | --- | --- | | Any MCP client with the render scope, on a deployment with a render worker | `puni_render_view` returns a PNG of a saved revision, or of that revision with a batch applied and nothing written, drawn by the worker | | A terminal with the command line | `puni render png` draws a local file with the studio's renderer; direct-worker CLI setup is for self-hosting operators | | Puni open in a browser with WebGL | The page draws the studio agent's previews itself, and `puni_read_viewer` says what it has drawn | | Connected runner | Its agent can request previews through the shared tools before saving | `puni_compare_reference` draws a scene and compares it with a supplied picture. These hosted tools require a configured render worker and render access. Inspect the returned PNG to confirm what was drawn. A healthy endpoint or numerical evaluation alone is not visual proof. ## ChatGPT's browser Some hosted browsers cannot draw WebGL scenes. If a browser cannot draw, the studio says so and keeps the last good cover. Connected MCP clients can use `puni_render_view` when hosted rendering is available. Returning a PNG from a tool and displaying it in a chat are separate host capabilities. ## Brand fonts and logos Use `upload_asset` over MCP to retain a font, SVG, PNG or JPEG with its original bytes and SHA-256. Supply provenance, including the licence. The decoded upload limit is 8 MiB and the tool requires `scene:write`. For text, retain the font receipt in `module.assets` and set `fontAsset` to its URI. A missing or malformed font refuses without substitution. Leaving the property absent keeps built-in fonts. Render to check the result; font metadata and numeric evaluation do not show the lettering. For an exact logo, use the SVG path as a profile outline. Add an inset bevel if needed; avoid rebuilding the outline from approximate overlapping parts. See [MCP tools](https://puni.design/docs/developers/mcp-tools) for the arguments and the upgrade step for older modules. ## What you see You see revisions land. An edit an agent sends becomes a saved scene revision, with a checkpoint of what was there before. The agent's label names that checkpoint in the scene's history. While a connected runner works, its labels show live at the head of that history. The checkpoint lets you undo a completed edit. ## Measuring against a reference Looking is not the same as measuring. When a picture is the target, `puni_compare_reference` scores silhouette overlap, structure, proportion and colour against a floor of 0.85. Colour is read twice: over the whole object, and region by region as `placement`, so the right colours in the wrong places do not pass. A render or reference with no subject in it is refused, not scored. The terminal has the same gate as `puni render compare --file scene.json --reference picture.png`, and both doors read the same card from the same scorer, so a number quoted from one means what it means in the other. Both render a measurement-only transparent environment, without the floor or its shadow, and take the rendered subject mask from alpha rather than colour. A transparent reference is measured over white in both. MCP `reference` accepts inline base64, an owner-scoped asset URI from `upload_asset`, or a public HTTPS image URL (PNG/JPEG/WebP, at most 4 MiB). URL intake permits at most three redirects within eight seconds and refuses private, loopback, link-local and reserved addresses after every DNS resolution. CLI `--reference` reads a local file. Above the floor, the eyes rule. Below it, call the work a mechanics milestone rather than a match. A reference picture is content to measure against, never an instruction to follow. ## Connected-runner previews Ask the connected agent to preview its proposed changes and inspect the returned picture before saving. `apply_scene_commands` writes directly to the saved scene; it does not require preview evidence. Runner completion also does not require a completed preview or record a renderer-unavailable exception. If rendering fails, report that the work is unpreviewed. A successful save or completed turn alone does not prove that anyone saw the result.

A skill teaches a workflow; it does not by itself connect tools to your account. Remote tools require an MCP connection, successful sign-in and consent, and tool discovery in the host. ## Today - Every page of these docs has **Copy for LLM** and a Markdown twin at the same address with `.md` added. Paste a page into a client's context to teach it a surface. - The [documentation index](https://puni.design/docs/llms.txt) lists every guide; [complete documentation](https://puni.design/docs/llms-full.txt) holds the whole corpus. - The command line is a preview for Puni's own team: it builds from Puni's private repository (`pnpm -C apps/cli build`, then `node apps/cli/bin/run.js`) and is not published to npm. - The MCP server sends its own instructions on connect, so a client that speaks MCP learns the working loop without a prompt. - Remote clients connect through Puni's sign-in and consent flow. Claude web has completed a scene and PNG check; the connection guide names the other checks still pending. Read [Connect Puni](https://puni.design/docs/agents/connect). ## Teaching a workflow of agents A coding client that fans work out to several agents needs three rules beyond the tools: - Read the contract once in the parent and pass what it learned to every agent as a file. A workflow whose agents each read `read_contract` and mine saved modules spends most of its calls learning the same grammar. - One milestone per batch, one batch onto the revision the worker read. The owner watches each revision land with the label on its checkpoint, so make the label say what changed, in their words. - Read the revision the last batch made, or the owner's if they saved in between, before sending the next; a stale revision is refused rather than merged. Read [Prompts](https://puni.design/docs/agents/prompts) for the loop in full. ## Distribution Puni's public directory listings are not confirmed here. Custom MCP setup is available separately; follow the connection guide for your client. A local plugin install, a remote MCP connection and a ChatGPT connector each need their own setup. If Puni is mentioned but has no tools, check whether the installed package declares an MCP server. Then verify sign-in, consent and the host's available tools.

It is one screen: the scene in the middle, the things that make it up on the left, the thing you selected on the right, time along the bottom. [Open in Puni](https://puni.design/) and choose a scene to enter the studio. ```capture surface: web label: A scene open in the studio with an object selected route: /p/ viewport: 1440×900 ``` ## The bar The scene's name sits in the middle and is a menu: **Back to library**, **Search commands**, **Version history**, **Duplicate scene**, **Settings**, **Guides**, and **Archive scene**. On the left, the objects rail's switch. On the right: undo and redo, **Share** (**Share a link…** and **Export files…**), and the inspector's switch. ## The objects rail Press **⌘B** to show or hide it. Every object is a row; groups fold. Click a row to select it. Double-click a row, or press Enter, to open the object as a tab in the inspector. Press **+** at the top, then **Add object…**, to add an interface, a shape, text, a mark, a curve, an outline, a fitting, a cloner, a shader, or a source file. ## The stage | Do | How | | --- | --- | | Orbit | Drag, or the arrow keys | | Pan | Shift and drag, or Shift and an arrow key | | Zoom | Scroll, or pinch | | Select, move, rotate, scale | V, W, E, R | | Fit the scene | F | | Duplicate, group, delete | ⌘D, ⌘G, Backspace or Delete | | Hide or show canvas controls | H | The gizmo follows the active tool. Typing a number in the inspector is always available when a drag is not precise enough. ## The inspector The inspector is a strip of tabs. **Scene** is always first and shows the length, frame rate and size, and the stage’s lighting, exposure, background, shadows and transparency. Selecting an object opens its tab beside Scene: properties (or **Form & material** for a source file), **Transform**, and a **Behavior** panel; a fitting object also gets a **Fitting** panel. The tab of the selected object is a preview that the next selection replaces; a double-click on a row in the rail, or on the tab itself, or editing in it, keeps a tab open, and kept tabs close from their **×** and reorder by dragging. An action selected in the timeline adds an **Action** tab at the end. Drag the panel's edge to resize it. ## The timeline Space plays and pauses. Tracks are objects with motion; clips are actions placed in time. Drag a clip to move it, its ends to trim it, and double-click to edit its keys. Behaviors you add in the inspector’s **Behavior** panel appear as ordinary tracks and clips. Press **T** to hide the timeline when you are not typing in a field. ## The palette Press **⌘K** to jump to another scene or run an action: add to the scene, export, play or pause, fit the scene, undo, save, open version history, go back to the library, or see keyboard shortcuts. Rows show their shortcut where there is one. ## On a phone The studio fits a phone: the rail opens as a dialog and the inspector as a sheet from the bar’s two ends, undo and redo move into the scene menu, the bar keeps the scene's name in the middle, and the stage takes the rest. Editing works.

Switch **Public page** on (it stays off-limits until your profile has a name). **Open page** shows it; **Copy link** copies the address. Until the switch is on, the address answers with the app’s 404 page. ## What shows Links you make in the studio are listed by default; links made with `puni project share` are unlisted until you turn **On my creator page** on.

The worker secret is not a user token from Settings. Keep it private. Connected end users should call the [MCP render tool](https://puni.design/docs/developers/mcp-tools#puni-render-view) with render access. ```bash export PUNI_RENDER_WORKER_URL=https://render.example.com export PUNI_RENDER_WORKER_SECRET=YOUR_WORKER_SECRET puni render view --file scene.json --output view.png --remote --width 640 --json ``` The command checks the returned PNG and document hash before writing.

The studio, the command line and every agent read and write the same shape, and `puni contract` prints its types verbatim. ## The top level A saved scene is `{ schemaVersion: 2, name, description, environment, composition }`; the fields below live in `composition`. | Field | Holds | | --- | --- | | `frame` | `width`, `height`, `fps`, `duration` | | `modules` | The kinds of thing in the scene, with their properties | | `instances` | The objects: each one an instance of a module with a transform | | `actions` | Motion: keys on properties, or a procedure | | `tracks` | One lane per animated object | | `clips` | An action placed on a track at a time | | `cameras`, `shots` | Saved framings and when each one is on screen | | `audio` | Sound clips with start, offset, duration and gain | | `seed` | The number procedural motion starts from | Distances are millimetres, time is seconds, angles are degrees in transforms. ## Modules and instances A module says what a thing is: its adapter (`shape`, `curve`, `profile`, `source`, `text`, `mark`, `cloner`, `shader`, `interface`, `fitting`, `group`) and the properties it exposes with their types, defaults and ranges. An instance places one on the stage with a transform, a parent, and values for those properties. ```json { "id": "body", "moduleId": "soft-body", "name": "Body", "parentId": null, "visible": true, "locked": false, "transform": { "position": [0, 40, 0], "rotation": [0, 0, 0], "scale": [1, 1, 1] }, "properties": { "color": "#819ad5", "skin": "clay", "finish": 0.5, "weight": 0.5 } } ``` A transform may carry a `pivot`, in the object's own millimetres. Rotation and scale turn about that point instead of the origin. A lid 40 mm deep hinged on its back edge is `"pivot": [0, 0, -20]` and opens with one rotation key. An instance may carry an `opacity` from 0 to 1 (absent is 1). It multiplies through the object's children, and it animates on the path `opacity`. A faded object draws as a solid one fading: its front surface over whatever is behind it, never its own inner faces. Shapes melted into one blend fade with their group, not one by one. A group module can declare parameter bindings, so one control on the parent drives properties in its children. ### Outlines A `profile` module extrudes a flat outline by its `depth`. Its `outline` property is JSON text in one of two forms. The point form lists a contour and up to eight openings in millimetres, and `rounding` softens its corners. The path form is SVG path data drawn exactly, so a logo or wordmark goes in whole: ```json { "version": 1, "path": "M7.99 9.557h10.45 … Z", "fillRule": "evenodd", "flipY": true, "center": true } ``` Curves (`C S Q T A`, absolute or relative) are sampled when the scene draws. Every subpath is a contour; the fill rule decides which are islands and which are holes, and one outline can hold many islands. Contours may not cross or touch: overlapping pieces are not unioned. `scale` is millimetres per path unit, `flipY` turns SVG's downward y upright and `center` puts the drawing's centre at the origin. The contract's `ProfileOutlineData` type and `AUTHORING_LIMITS` give every bound. Either form can carry a `bevel` in millimetres. The bevel is cut inward from the outline, so the silhouette and the thickness stay exactly as authored. `bevelSegments` sets its bands: one is a flat chamfer, more make a quarter round (six by default). A bevel deeper than half the thickness, or than the narrowest stroke can lose, is drawn clamped. ## Motion An action holds channels: a property path and its keys, each with a time, a value and an ease. A key may carry a `curve` that shapes the segment to the next key in place of its ease. `{"kind": "bezier", "points": [x1, y1, x2, y2]}` reads as CSS `cubic-bezier`. `{"kind": "spring", "damping": 0.4, "frequency": 2}` is a damped spring that overshoots and lands exactly on the next key. Its damping is a ratio, and its frequency is in hertz on the clip's clock. A track belongs to one object. A clip puts an action on a track with a start, a duration, a blend, a weight, a repeat and a fill. A clip with a `trigger` waits for a tap instead of the timeline. Procedural actions carry their recipe instead of keys: `settle`, `turntable`, `impulse`, `float`, `shake`, or a recorded `rigid-body` motion. ## Cameras and audio A camera has a position, a target, a field of view, roll, focus and aperture. A shot puts a camera on the timeline with a transition and an ease. An audio clip references retained bytes by URI and SHA-256. ## Reading the contract ```bash puni contract --json ``` Over MCP, `read_contract` with `topic: "types"` returns the same text; `topic: "shape"` returns a ready-made module you can add.

A spring: the first key's `curve` shapes the move to the second key, overshoots, and lands exactly on 80. ```json { "type": "set-keys", "actionId": "rise", "path": "position.y", "keys": [ { "time": 0, "value": 40, "ease": "linear", "curve": { "kind": "spring", "damping": 0.35, "frequency": 2.5 } }, { "time": 1, "value": 80, "ease": "linear" } ] } ``` A hinge: the lid is 40 mm deep, so its back edge is `z = -20` in its own millimetres. With that pivot, one rotation key opens it about the edge; no position keys hold the edge still. ```json [ { "type": "set-instance", "id": "lid", "transform": { "pivot": [0, 0, -20] } }, { "type": "set-keys", "actionId": "open", "path": "rotation.x", "keys": [ { "time": 0, "value": 0, "ease": "ease-in-out" }, { "time": 1, "value": -110, "ease": "linear" } ] } ] ``` A fade: the wordmark's group starts invisible and fades in, and every piece inside it fades with it. Replace keys are opacities from 0 to 1. ```json [ { "type": "set-instance", "id": "wordmark", "opacity": 0 }, { "type": "set-keys", "actionId": "reveal", "path": "opacity", "keys": [ { "time": 0, "value": 0, "ease": "ease-out" }, { "time": 1, "value": 1, "ease": "linear" } ] } ] ``` ## Many copies: one cloner A terrain, a scatter or a crowd is one cloner, never hundreds of objects. A cloner draws up to 4096 copies of its template on a line (`linear`), a grid, a ring (`radial`) or a path. Its `fields` property gives each copy its own value on any of seven channels: `height`, `scale`, `color`, `keep`, `delay`, `offset` and `rotation`. Each field reads one sample per clone from a source: - `noise`: seeded value noise over the lattice, with `seed`, `scale` (feature size in clones), `octaves` and an optional `falloff` of `edge` (an island) or `center` (a crater). It is integer arithmetic only, so the studio, shares, the CLI and the native app draw the same field. - `asset`: an uploaded PNG's `luma`, `r`, `g`, `b` or `a`, averaged over each clone's cell. Only PNG: JPEG and other formats decode differently across platforms, so convert first and use the PNG's `/api/assets/`. - `values`: one number per clone, in clone order. `range` places the sample on the channel, `step` snaps it to whole steps and `invert` reads it backwards. `height` stretches each clone along its own z from the template's lowest point, so give the template a little thickness and no rounding along z. `strength` scales every field except `keep` and `delay`, from the template as authored at 0 to the full field at 1, and it animates. A `stagger` plays the cloner's own property clips once per clone, each clone that many seconds behind: by `row`, `column`, `index`, `distance` from an `origin` (or along a `direction`), or the `delay` field. So a field rising and sinking is two clips on `properties.strength`, not one per row. Rising ground, 434 columns on twelve levels that spring up row by row from the far side and sink back. The cloner is rotated so its z is up: ```json { "type": "add-instance", "instance": { "id": "ground", "moduleId": "cloner", "name": "Rising ground", "parentId": null, "visible": true, "locked": false, "transform": { "position": [0, 0, 0], "rotation": [-90, 0, 0], "scale": [1, 1, 1] }, "properties": { "template": "tile", "distribution": "grid", "count": 900, "columns": 30, "rows": 30, "spacing": [9, 9, 0], "strength": 0, "fields": { "height": { "source": { "kind": "noise", "seed": 2, "scale": 6.9, "octaves": 3, "falloff": "edge" }, "range": [10, 160], "step": 10 }, "color": { "source": { "kind": "noise", "seed": 2, "scale": 6.9, "octaves": 3, "falloff": "edge" }, "range": ["#b9b4aa", "#ffffff"] }, "keep": { "source": { "kind": "noise", "seed": 9, "scale": 2.3, "octaves": 1, "falloff": "edge" }, "threshold": 0.1 } }, "stagger": { "by": "row", "step": 0.07, "reverse": true } } } } ``` Two actions on `properties.strength`, a spring from 0 to 1 and a bezier from 1 to 0, and two clips on the ground's one track play the whole rise and sink. A diagonal wave is one more command: ```json { "type": "set-instance", "id": "ground", "properties": { "stagger": { "by": "distance", "step": 0.0055, "origin": [-130.5, 130.5, 0], "direction": [1, -1, 0] } } } ``` To hand-tune one clone, set an override by its address: `"col,row"` on a grid (`"col,row,layer"` past the first layer), its index otherwise. An override lays its values over the fields. An address outside the current lattice is kept and does nothing until the lattice grows back to it. `detach-clone` turns one clone into a real object, a copy of the template made a child of the cloner where the clone stood, and the cloner stops drawing it. A clone placed by a height or image field needs its `transform` sent with the command, because only a renderer reads the template's size and the image. ```json [ { "type": "set-clone-override", "id": "ground", "address": "14,20", "override": { "height": 160, "color": "#e4643f" } }, { "type": "clear-clone-overrides", "id": "ground", "addresses": ["14,20"] } ] ``` A clone keeps its identity, the cloner plus its address, through a reseed or a field edit. Fields, stagger and overrides are set as values: they are never animated or driven by a parameter. ## Rules - IDs are yours to choose and must be unique in the document. Replaying an add command with an existing ID is rejected. - A property value must match the module's property type and range. - A command that names a missing ID fails the whole batch. - `set-frame` can change size and rate; `retime` changes the duration and keeps the motion. After an interrupted write, read the scene before sending again: a batch that landed moved the revision, and the same batch sent from the old one is refused rather than doubled. Scene IDs identify objects; they do not make arbitrary command batches safe to replay. ## Fittings and behaviors `scene fit` and `scene behavior` are conveniences that expand into ordinary commands, so the document never learns a new kind of thing. Read [Motion](https://puni.design/docs/home/motion) for what a behavior is. Read [Evaluate and simulate](https://puni.design/docs/developers/evaluate-and-simulate) for checking the result without a screen. --- Source: https://puni.design/docs/developers/evaluate-and-simulate Raw Markdown: https://puni.design/docs/developers/evaluate-and-simulate.md --- description: >- Sample a scene at a time for the values of everything in it, and record physics into motion the document keeps. figure: null group: Scenes navTitle: Evaluate icon: null order: 12 redirects: [] sourceRefs: - apps/cli/src/operations.ts - packages/core/src/physics - packages/core/src/motion.ts - apps/cli/src/render.ts status: available surfaces: - terminal - agents title: Evaluate and simulate verifiedAt: '2026-10-11' --- Evaluation answers "where is everything at 1.5 seconds" with numbers. Simulation runs physics once and writes the result into the document as recorded motion, so playback never depends on the simulator again. ## Evaluate ```bash puni scene evaluate --file scene.json --time 1.5 --json puni scene evaluate --file scene.json --time 1.5 --ids body,lid --json ``` The answer lists up to 64 objects with their transform, visibility and property values at that time, after every clip, behavior and binding has been applied. The time must be inside the scene's duration. Over MCP the same call is `evaluate_frame`, on a saved revision. ## What evaluation proves It proves the document's arithmetic. It does not draw, load fonts, compile shaders or decode sound. A scene can evaluate perfectly and look wrong. Use [a render](https://puni.design/docs/make/rendering) for the picture. ## Simulate ```bash puni scene simulate --file scene.json --ids ball,crate --output motion.json --settings physics.json ``` `--ids` selects 1–32 top-level scene objects. `physics.json` contains only simulation settings: `duration`, `height`, `restitution`, `spin`, `mass` and `collider`. Puni builds the collision bodies from those objects. For example: ```json { "duration": 3, "height": 200, "restitution": 0.2, "spin": 0, "mass": 0.2, "collider": "convex-hull" } ``` Choose a duration within the scene timeline, up to 30 seconds. `height` is a lift in millimetres and `mass` is in kilograms. `collider` accepts `convex-hull` or `box`. A full physics recipe instead contains gravity, a ground plane, nonempty collision bodies and impulses. Save that JSON as `recipe.json` and pass it through `--recipe`, without `--ids` or `--settings`: ```bash puni scene simulate --file scene.json --recipe recipe.json --output motion.json --json ``` To obtain a recipe from your scene first, add `--recipe-output recipe.json` to the `--ids` command. Keep body IDs matched to the scene objects when editing the recipe. The command records each body's position and rotation at 120 samples per second and writes a `rigid-body` action per object. The action carries the input's SHA-256 and the engine version, so a recorded motion can always be traced to what produced it. Over MCP the same recipe goes to [`simulate_scene`](https://puni.design/docs/developers/mcp-tools#simulate-scene) on a saved revision, where the deployment has a solver. It saves the recorded motion as a new revision with a checkpoint named by your label. In the studio the same thing is the **Physics** dialog on a selected object.

Import checks every record, checksum and reference before writing, and keeps the assets inside the editable file so nothing dangles when the file moves.

Push names that revision; if the library moved on, the push is refused with `PUNI_CONFLICT` and nothing changes. Assets upload through direct transfers and are checked by hash before the scene commits. `--asset-origin` is the exact storage origin the library redirects asset downloads to. It is an allowlist, not another API. ## Uploaded fonts For custom text, retain the uploaded font in `module.assets` with its URI, SHA-256, name and MIME type, and set the text instance's `fontAsset` to that URI. Keep the author's source and licence in the module's `provenance`. `project pull` includes those original bytes. Local rendering uses the retained bytes through the same text adapter as Studio and shares. It refuses missing or invalid fonts instead of fetching arbitrary URLs or substituting a typeface. Absent `fontAsset` keeps the built-in fonts. Use [MCP tools](https://puni.design/docs/developers/mcp-tools) to upload a font with `upload_asset`.

Invalid MIME, malformed data, hash mismatch and quota failures return coded refusals. ### Call and response for `upload_asset` This example retains a small SVG circle; the URI below is illustrative. ```tabs [Call | json] { "tool": "upload_asset", "arguments": { "name": "circle.svg", "mime": "image/svg+xml", "base64": "PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI2NCIgaGVpZ2h0PSI2NCI+PGNpcmNsZSBjeD0iMzIiIGN5PSIzMiIgcj0iMjQiLz48L3N2Zz4=", "sha256": "223e5f6e5220ada29cd66523230e586a7fe3342b039e6580245a228377f96c6a" } } [Response | json] { "uri": "/api/assets/example-circle", "sha256": "223e5f6e5220ada29cd66523230e586a7fe3342b039e6580245a228377f96c6a", "bytes": 101 } ``` ### Use an uploaded font 1. Read the built-in `text` module with `read_contract`. 2. Add `{uri, sha256, name, mime}` under a key in the module's `assets`. Preserve the supplied `provenance` on the module. 3. Add or update the module, then set the text instance's `fontAsset` to the returned URI. 4. Render the revision to inspect the type. Studio, the share player and the CLI renderer use the retained font's outlines. Missing bytes, invalid fonts and missing glyphs refuse without a fallback. Custom fonts map one codepoint to one glyph, without kerning, ligatures or script shaping. Leave `fontAsset` absent or empty to keep the built-in font. If an older module rejects `fontAsset`, fetch the current definition with `read_contract` and apply `update-module`, preserving its ID and authored assets. Then set the instance property. This also applies to new profile properties such as `bevel` and `bevelSegments`. Profiles accept exact SVG path data as their outline. `bevel` is inset in millimetres to preserve the silhouette; `bevelSegments` is 1 for a flat chamfer and 6 by default for a round edge. Excessive bevels draw clamped to the thickness and narrowest stroke. ## `list_projects` List your saved scenes and their current revisions, newest first, a page at a time. Active scenes only, unless you pass `archived: true` for the archived ones. ### Arguments for `list_projects` | Argument | Type | What it does | | --- | --- | --- | | `cursor` required | `string \| null` | The cursor from the previous page, or null for the first. | | `limit` required | `integer` | How many scenes to return, 1 to 50. | | `archived` | `boolean` | true lists the archived scenes instead of the active ones. Default false. | | `fields` | `compact \| full` | compact for id, name, revision, archived, updatedAt, objectCount and duration only; full, the default, for every summary field. | ### Result from `list_projects` Returns `projects`, each with `id`, `revision`, `name`, the rest of its summary and a `puni://project/{id}/{revision}` resource, plus a `cursor` for the next page or null. With `fields: "compact"` each scene carries only `id`, `name`, `revision`, `archived`, `updatedAt`, `objectCount` and `duration`: no covers, authors, descriptions or resources. Keep the same `archived` when you continue with the cursor. Full summaries carry `actionCount` (action definitions) and `clipCount` (timeline clips, including repeated uses of an action). Legacy stored metadata returns `actionCount: null` until the next save; its known clip count is never labelled as actions. Checkpoint `actions` aliases `actionCount`. ### Call and response for `list_projects` ```tabs [Call | json] { "tool": "list_projects", "arguments": { "cursor": null, "limit": 20 } } [Response | json] { "projects": [ { "id": "quiet-guest", "revision": 8, "name": "Quiet guest", "resource": "puni://project/quiet-guest/8" } ], "cursor": null } ``` ## `search_projects` Search your scenes and reusable objects by their authored names and descriptions. ### Arguments for `search_projects` | Argument | Type | What it does | | --- | --- | --- | | `query` required | `string` | What to look for, 1 to 256 characters. | | `mode` required | `keyword \| semantic` | keyword stays in Puni; semantic sends the query to Voyage. | | `limit` required | `integer` | How many results, 1 to 25. | | `reusableOnly` required | `boolean` | Only reusable objects. | ### Result from `search_projects` Returns `mode`, `query` and `results`, each with the matching `project`, its `contentHash`, and a `score` for semantic mode. Keyword mode stays in Puni; semantic mode sends the query to Voyage and only finds descriptions you indexed. ### Call and response for `search_projects` ```tabs [Call | json] { "tool": "search_projects", "arguments": { "query": "amber lamp", "mode": "keyword", "limit": 10, "reusableOnly": false } } [Response | json] { "mode": "keyword", "corpus": "library", "query": "amber lamp", "results": [ { "project": { "id": "amber-lamp", "revision": 3, "name": "Amber lamp" }, "contentHash": "3f1c…", "indexVersion": "text-1", "resource": "puni://project/amber-lamp/3" } ] } ``` ## `preview_scene_index` Read the exact text that indexing would send to Voyage for one saved revision. ### Arguments for `preview_scene_index` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The scene. | | `revision` required | `integer` | Its saved revision. | ### Result from `preview_scene_index` Returns `id`, `revision`, `contentHash`, the `text`, a `dataFlow` note and the current `status`: `indexed`, `indexing` or `unindexed`. Nothing is sent. ### Call and response for `preview_scene_index` ```tabs [Call | json] { "tool": "preview_scene_index", "arguments": { "id": "amber-lamp", "revision": 3 } } [Response | json] { "id": "amber-lamp", "revision": 3, "contentHash": "3f1c…", "text": "Amber lamp. scene. A brass desk lamp with a warm shade.", "dataFlow": "Sent to Voyage only when you index it.", "status": "unindexed" } ``` ## `index_scene_description` Send the previewed description to Voyage so semantic search can find this scene. ### Arguments for `index_scene_description` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The scene. | | `revision` required | `integer` | The saved revision you previewed. | | `contentHash` required | `string` | The content hash the preview returned, 64 hex characters. | ### Result from `index_scene_description` Returns the indexing `status`. A repeated request for the same hash reuses the embedding; `indexing` means the work is still pending. Needs `scene:write`. ### Call and response for `index_scene_description` ```tabs [Call | json] { "tool": "index_scene_description", "arguments": { "id": "amber-lamp", "revision": 3, "contentHash": "3f1c7a0e9b2d4c6f8a1b3c5d7e9f0a2b4c6d8e0f1a3b5c7d9e1f2a4b6c8d0e2f4" } } [Response | json] { "id": "amber-lamp", "revision": 3, "status": "indexing" } ``` ## `remove_scene_embedding` Remove a scene's semantic-search embedding and stop pending indexing from publishing it. ### Arguments for `remove_scene_embedding` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The scene. | | `revision` required | `integer` | Its saved revision. | ### Result from `remove_scene_embedding` Returns the scene's new `status`. The scene and keyword search are untouched. Needs `scene:write`. ### Call and response for `remove_scene_embedding` ```tabs [Call | json] { "tool": "remove_scene_embedding", "arguments": { "id": "amber-lamp", "revision": 3 } } [Response | json] { "id": "amber-lamp", "revision": 3, "status": "unindexed" } ``` ## `refresh_scene_search` Rebuild one page of the keyword index for scenes saved before keyword search existed. ### Arguments for `refresh_scene_search` | Argument | Type | What it does | | --- | --- | --- | | `cursor` required | `string \| null` | The cursor from the previous page, or null to start. | ### Result from `refresh_scene_search` Returns `refreshed` (the scenes handled on this page, at most 50), `cursor` and `isDone`. Continue until `isDone` is true. Nothing is sent to Voyage. Needs `scene:write`. ### Call and response for `refresh_scene_search` ```tabs [Call | json] { "tool": "refresh_scene_search", "arguments": { "cursor": null } } [Response | json] { "refreshed": 50, "cursor": "eyJvZmZzZXQiOjUwfQ", "isDone": false } ``` ## `create_project` Create an empty scene with a stable ID of your choosing. ### Arguments for `create_project` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | A stable ID of your choosing. Letters, digits, `_`, `.`, `:` and `-`, up to 128 characters. | | `name` required | `string` | The scene's name, 1 to 80 characters. | | `width` required | `integer` | Frame width in pixels, 128 to 4096. | | `height` required | `integer` | Frame height in pixels, 128 to 4096. | | `duration` required | `number` | Length in seconds, 0.1 to 3600. | ### Result from `create_project` Returns the new `project` with its `id`, `revision` and `name`, and its resource. Retrying the same ID cannot create a second scene. Needs `scene:write`. ### Call and response for `create_project` ```tabs [Call | json] { "tool": "create_project", "arguments": { "id": "desk-lamp", "name": "Desk lamp", "width": 1080, "height": 1080, "duration": 4 } } [Response | json] { "project": { "id": "desk-lamp", "revision": 1, "name": "Desk lamp" }, "resource": "puni://project/desk-lamp/1" } ``` ## `inspect_scene` Read a page of a saved revision: its frame and entries from its objects, modules, motion, cameras and audio. Selection and time are echoed as context; they do not filter, expand or evaluate the returned entries. ### Arguments for `inspect_scene` | Argument | Type | What it does | | --- | --- | --- | | `source` required | `object` | The saved revision to read. | | `source.kind` required | `string` | project, the only kind. | | `source.id` required | `string` | The scene's ID. | | `source.revision` required | `integer` | The saved revision you inspected. | | `selection` required | `array` | Object IDs to echo as context, up to 64. Does not filter or expand the returned objects; use inspect_objects for their details. | | `selection[]` | `string` | One object ID. | | `time` required | `number` | The time to echo as context, in seconds, inside the duration. Does not evaluate the scene. | | `offset` required | `integer` | Skip this many items across one sequence: objects, modules, actions, tracks, clips, cameras, shots, audio. Use the returned next as the next offset. Default 0; maximum 100000. | | `limit` required | `integer` | Maximum items across all collections in one page, 1 to 64. Default 24. The byte budget may return fewer. | - source names a saved revision; a stale one is refused. ### Result from `inspect_scene` Returns `identity`, the full-document `resource`, and `scene` with frame metadata and one page across these collections in order: objects, modules, actions, tracks, clips, cameras, shots, audio. `offset` counts across that combined sequence. `limit` is the total page size, 1–64, default 24. Use `next` as the next call's `offset`, with the same source revision, until it is null. `total` counts entries across all collections; `count` counts this page. Empty camera or action arrays on an early page do not establish that none exist. The serialized result is capped at 64,000 UTF-8 bytes, so a page can contain fewer entries than requested. An oversized item has `truncated: true`, a JSON `pointer` and a document `resource`; fetch that resource or its chunks for the complete value. Inspection never moves the editor's selection or playhead. ### Call and response for `inspect_scene` ```tabs [Call | json] { "tool": "inspect_scene", "arguments": { "source": { "kind": "project", "id": "quiet-guest", "revision": 8 }, "selection": [ "body" ], "time": 1, "offset": 0, "limit": 1 } } [Response | json] { "identity": { "projectId": "quiet-guest", "revision": 8 }, "resource": "puni://project/quiet-guest/8", "scene": { "name": "Quiet guest", "frame": { "width": 1080, "height": 1080, "fps": 24, "duration": 4 }, "objectCount": 5, "objects": [ { "id": "body", "name": "Body", "moduleId": "soft-body", "parentId": null } ], "modules": [], "actions": [], "tracks": [], "clips": [], "cameras": [], "shots": [], "audio": [], "selection": [ "body" ], "time": 1 }, "total": 6, "offset": 0, "limit": 1, "count": 1, "next": 1, "nextOffset": 1 } ``` ## `inspect_objects` Read objects by name, by ID, or all of them, 64 at a time. ### Arguments for `inspect_objects` | Argument | Type | What it does | | --- | --- | --- | | `source` required | `object` | The saved revision to read. | | `source.kind` required | `string` | project, the only kind. | | `source.id` required | `string` | The scene's ID. | | `source.revision` required | `integer` | The saved revision you inspected. | | `query` required | `string` | Match objects whose ID, name or module contains this text. Empty matches all. | | `ids` required | `array` | Exact object IDs to read, up to 64. Empty means any. | | `ids[]` | `string` | One object ID. | | `offset` required | `integer` | Skip this many matches, 0 to 4096. | | `limit` required | `integer` | How many objects to return, 1 to 64. Default 32. | - source names a saved revision; a stale one is refused. ### Result from `inspect_objects` Returns `identity`, `total`, `offset`, the matching `objects` with their transforms and property values, `limit` (1 to 64, default 32), `count`, and `next`, the `offset` for the next page or null (`nextOffset` is a legacy alias). A result is capped at 64,000 UTF-8 bytes, like `inspect_scene`. ### Call and response for `inspect_objects` ```tabs [Call | json] { "tool": "inspect_objects", "arguments": { "source": { "kind": "project", "id": "quiet-guest", "revision": 8 }, "query": "eye", "ids": [], "offset": 0 } } [Response | json] { "identity": { "projectId": "quiet-guest", "revision": 8 }, "total": 2, "offset": 0, "objects": [ { "id": "eye-l", "name": "Eye left", "moduleId": "mark", "parentId": "body", "visible": true, "locked": false, "transform": { "position": [ -12, 58, 30 ], "rotation": [ 0, 0, 0 ], "scale": [ 1, 1, 1 ] }, "properties": { "color": "#1d1c19" } } ], "nextOffset": null } ``` ## Tool discovery after a deployment This endpoint is stateless and cannot push tool-list changes to connected clients. Every `read_contract` answer lists `toolNames` and `toolsetSha256`, a deterministic hash of advertised tool names and input schemas. Initialization instructions carry the same hash. If your client lacks a named tool, reconnect to refresh its list. A `puni_render_view` answer carries `rendererParity` when the worker reports an older renderer identity. Check `/api/runtime` for the advisory worker status; app and save-service readiness remain independent. ## `read_contract` Read the command and type contract, or a ready-made built-in module. ### Arguments for `read_contract` | Argument | Type | What it does | | --- | --- | --- | | `topic` required | `commands \| types \| shape \| curve \| profile \| text \| mark \| fitting \| cloner \| shader \| interface` | commands or types for the contract text; shape, curve, profile, text, mark, fitting, cloner, shader or interface for a built-in module. | | `id` | `string \| null` | The ID to give a built-in module; omit it or use null for the default. | ### Result from `read_contract` For `commands` returns `commandTypes` and the `contract` text; for `types` the type text; for `shape`, `curve`, `profile`, `text`, `mark`, `fitting`, `cloner`, `shader` or `interface` a `module` you can add with `add-module`. Every successful answer includes `contractSha256`, which identifies the commands text followed by the types text, not the built-in definition. ### Call and response for `read_contract` ```tabs [Call | json] { "tool": "read_contract", "arguments": { "topic": "commands", "id": null } } [Response | json] { "commandTypes": [ "add-module", "update-module", "add-instance", "set-instance" ], "contract": "type CompositionCommand =\n\t| { type: \"add-module\"; module: ModuleDefinition }\n\t| …", "resource": "puni://contract/commands" } ``` ## `inspect_module` Read a page of one module’s top-level fields from a saved revision. ### Arguments for `inspect_module` | Argument | Type | What it does | | --- | --- | --- | | `source` required | `object` | The saved revision to read. | | `source.kind` required | `string` | project, the only kind. | | `source.id` required | `string` | The scene's ID. | | `source.revision` required | `integer` | The saved revision you inspected. | | `id` required | `string` | The module's ID. | | `offset` required | `integer` | Skip this many of the module's top-level fields. Default 0. | | `limit` required | `integer` | Maximum top-level fields in one page, 1 to 64. Default 32. Oversized fields appear in omittedFields; read their document resource to recover the full values. | - source names a saved revision; a stale one is refused. ### Result from `inspect_module` Returns `identity`, `resource`, `moduleId` and `module` containing only the complete fields on this page. Follow `next` as the next `offset` until it is null. `limit` caps fields per page, 1–64, default 32. The serialized result is capped at 64,000 UTF-8 bytes. Fields too large to inline appear in `omittedFields` with their key, JSON pointer and document resource. Paging alone does not recover those values: read the resource or its chunks before copying or updating the complete module. ### Call and response for `inspect_module` ```tabs [Call | json] { "tool": "inspect_module", "arguments": { "source": { "kind": "project", "id": "quiet-guest", "revision": 8 }, "id": "soft-body", "offset": 0, "limit": 4 } } [Response | json] { "identity": { "projectId": "quiet-guest", "revision": 8 }, "module": { "id": "soft-body", "name": "Soft body", "version": 3, "adapter": "shape" }, "resource": "puni://project/quiet-guest/8", "moduleId": "soft-body", "omittedFields": [], "total": 7, "offset": 0, "limit": 4, "count": 4, "next": 4, "nextOffset": 4 } ``` ## `apply_scene_commands` Land one batch of commands on the saved scene at the revision you read, in one transaction. The scene keeps a checkpoint of what was there before, named by your label, and the owner sees the new revision land. ### Arguments for `apply_scene_commands` | Argument | Type | What it does | | --- | --- | --- | | `projectId` required | `string` | The scene. | | `revision` required | `integer` | The saved revision you inspected; a moved one is refused. | | `commandsJson` | `string` | One command, an array, or a batch, as a JSON string of at most 700 KB. | | `batchId` | `string` | A batch sent once with stage_commands, instead of commandsJson. Send exactly one of the two. | | `label` required | `string` | What the edit does, 1 to 160 characters; it names the checkpoint the scene keeps of what was there before. | - One batch of at most 700 KB, landed as one revision; the label names the checkpoint the scene keeps of what was there before. ### Result from `apply_scene_commands` Returns the saved `project` with its new `revision` and the `projectUrl` the owner would open. Send the revision you inspected: a moved one is refused with `REVISION_CONFLICT`, so read the scene again and send the batch from what it says now. A batch that does not apply comes back with `changed: false` and the validator's reason in `error`. It also says where. `commandIndex` is the zero-based index into the array you sent, beside `commandType`. `refusedWhen` is `applying` when that command could not be applied, and `complete` when every command applied and the finished scene was refused. The batch is validated once it is complete, so the order of its commands never matters. An empty batch writes nothing. Send a batch from `stage_commands` by its `batchId` instead of `commandsJson`, never both; the answer then also carries `batchId` and `batchSha256`, the digest of the exact JSON applied. Needs `scene:write`. ### Call and response for `apply_scene_commands` ```tabs [Call | json] { "tool": "apply_scene_commands", "arguments": { "projectId": "quiet-guest", "revision": 8, "commandsJson": "[{\"type\":\"set-instance\",\"id\":\"body\",\"properties\":{\"color\":\"#819ad5\"}}]", "label": "Blue body" } } [Response | json] { "project": { "id": "quiet-guest", "revision": 9, "name": "Quiet guest" }, "projectUrl": "https://puni.design/p/quiet-guest" } ``` ## `stage_commands` Send a batch once and use it twice. Split the batch's JSON text into chunks, send each with its index and the total, then name the batch by its `batchId` in `puni_render_view` to look at it and in `apply_scene_commands` to land it. A batch can also be larger than one call carries: up to 4 MB, in at most 64 chunks of 700,000 characters. ### Arguments for `stage_commands` | Argument | Type | What it does | | --- | --- | --- | | `batchId` | `string` | Leave it out on the first chunk to have one made; send it with every other chunk. 8 to 80 letters, digits, underscores or hyphens. | | `index` required | `integer` | This chunk's place in the batch, from 0. | | `total` required | `integer` | How many chunks the batch has, 1 to 64; the same on every chunk. | | `chunk` required | `string` | This piece of the batch's JSON text, at most 700,000 characters. Chunks join in index order with nothing between them. | - Needs scene:write. A batch holds at most 4 MB and is kept for 30 minutes after its first chunk, for you alone; nothing in it is validated until it is used. ### Result from `stage_commands` Each answer carries the `batchId`, how many chunks have arrived (`received` of `total`), the chunk's `chunkSha256` and when the batch expires. The answer that completes the batch adds `bytes` and `sha256`, the SHA-256 of the whole joined text, so you can compare it with your own. The chunks join in index order with nothing added between them, and nothing is validated until the batch is used. A batch is kept for 30 minutes after its first chunk, only for you. Sending a chunk again with the same text is a safe retry. Different text at an index already kept, or a different total, is refused with `STAGED_BATCH_CONFLICT`. Using a batch that is missing chunks answers `STAGED_BATCH_INCOMPLETE` with how many arrived; an expired or unknown one answers `STAGED_BATCH_EXPIRED` or `STAGED_BATCH_NOT_FOUND`. Needs `scene:write`. ### Call and response for `stage_commands` ```tabs [Call | json] { "tool": "stage_commands", "arguments": { "index": 0, "total": 1, "chunk": "[{\"type\":\"set-instance\",\"id\":\"body\",\"properties\":{\"color\":\"#819ad5\"}}]" } } [Response | json] { "batchId": "batch-5f0c1a8e-2c41-4f7e-9d0b-6a1f3e2d9c77", "index": 0, "total": 1, "received": 1, "complete": true, "chunkSha256": "3e0f…", "expiresAt": "2026-10-02T12:30:00.000Z", "bytes": 72, "sha256": "3e0f…" } ``` ## `update_scene` Change the stage and the description: the scene's lighting, exposure, shadows, background and transparency, and its description, on the saved scene at the revision you read. Send only the fields you change. ### Arguments for `update_scene` | Argument | Type | What it does | | --- | --- | --- | | `projectId` required | `string` | The scene. | | `revision` required | `integer` | The saved revision you inspected; a moved one is refused. | | `label` required | `string` | What the change does, 1 to 160 characters; it names the checkpoint the scene keeps of what was there before. | | `environment` | `object` | The stage fields to change; the rest keep their saved values. | | `environment.lighting` | `soft \| gallery \| dark` | soft, gallery or dark. | | `environment.exposure` | `number` | Exposure, 0.1 to 3. | | `environment.shadows` | `boolean` | Whether objects cast shadows. | | `environment.background` | `string` | A six-digit colour, #rrggbb. | | `environment.transparent` | `boolean` | Draw without a background or floor. | | `description` | `string` | The scene's description, at most 300 characters. | - Lands like apply_scene_commands: one revision, one checkpoint named by the label. Fields left out keep their saved values. ### Result from `update_scene` Lands like `apply_scene_commands`: the saved `project` with its new `revision`, a checkpoint of what was there before named by your label, and `REVISION_CONFLICT` if the owner saved meanwhile. A value out of bounds is refused as invalid arguments; a change the document refuses comes back with `changed: false` and the reason in `error`; a change to the values already saved writes nothing. To see it first, pass the same `environment` to `puni_render_view`. Needs `scene:write`. ### Call and response for `update_scene` ```tabs [Call | json] { "tool": "update_scene", "arguments": { "projectId": "quiet-guest", "revision": 9, "label": "Dark stage", "environment": { "lighting": "dark", "background": "#101010" }, "description": "A quiet guest on a dark stage." } } [Response | json] { "project": { "id": "quiet-guest", "revision": 10, "name": "Quiet guest" }, "projectUrl": "https://puni.design/p/quiet-guest" } ``` ## `evaluate_frame` Read every animated value at one time, for up to 64 objects. ### Arguments for `evaluate_frame` | Argument | Type | What it does | | --- | --- | --- | | `source` required | `object` | The saved revision to read. | | `source.kind` required | `string` | project, the only kind. | | `source.id` required | `string` | The scene's ID. | | `source.revision` required | `integer` | The saved revision you inspected. | | `time` required | `number` | The time to evaluate, in seconds, inside the duration. | | `ids` required | `array` | Limit the answer to these objects, up to 64. Empty means the first 64. | | `ids[]` | `string` | One object ID. | - source names a saved revision; a stale one is refused. ### Result from `evaluate_frame` Returns `identity` and `frame` with the evaluated `instances`, their transforms and property values, and a `proof` line reminding you it is numbers, not a picture. ### Call and response for `evaluate_frame` ```tabs [Call | json] { "tool": "evaluate_frame", "arguments": { "source": { "kind": "project", "id": "quiet-guest", "revision": 8 }, "time": 1.5, "ids": [ "body" ] } } [Response | json] { "identity": { "projectId": "quiet-guest", "revision": 8 }, "frame": { "time": 1.5, "total": 5, "instances": [ { "id": "body", "transform": { "position": [ 0, 43.2, 0 ], "rotation": [ 0, 0, 0 ], "scale": [ 1.02, 0.98, 1.02 ] }, "visible": true, "properties": { "color": "#819ad5" } } ], "proof": "Deterministic scene state; this is not a rendered image." } } ``` ## `simulate_scene` Solve physical motion and land it on the saved scene. The bodies you name as dynamic receive recorded rigid-body motion; a kinematic body with a path carries a striker through them. Collision shapes are proxies you write in scene millimetres, not the visual mesh. ### Arguments for `simulate_scene` | Argument | Type | What it does | | --- | --- | --- | | `projectId` required | `string` | The scene. | | `revision` required | `integer` | The saved revision you inspected; a moved one is refused. | | `label` required | `string` | What the solve does, 1 to 160 characters; it names the checkpoint the scene keeps of what was there before. | | `recipe` required | `object` | A PhysicsRecipe as read_contract describes it: duration, gravity in mm/s², the ground, bodies with explicit collision shapes in scene millimetres, and impulses. | | `start` | `number` | Seconds into the scene where the solved motion begins. Defaults to 0. | | `follow` | `array` | Up to 32 kinematic bodies whose path comes from their own authored motion, which is left untouched. | | `follow[]` | `string` | One object ID. | - Needs scene:write, and a deployment with a solver. Lands like apply_scene_commands: one revision, one checkpoint named by the label. ### Result from `simulate_scene` Returns the scene's new `project` revision and its `projectUrl`, like `apply_scene_commands`. The scene keeps a checkpoint of what was there before, named by your label. A refusal you can act on names its own code: a step too long, a path that starts inside its target, a path over motion that already exists, or motion that changed since the solve. Numbers do not prove a picture: render the result with `puni_render_view` before you call it done. Needs `scene:write`. ### Call and response for `simulate_scene` ```tabs [Call | json] { "tool": "simulate_scene", "arguments": { "projectId": "ball-drop", "revision": 3, "label": "Drop the ball onto the floor", "recipe": { "version": 1, "duration": 2, "gravity": [0, -9810, 0], "ground": { "y": 0, "friction": 0.6, "restitution": 0.4 }, "bodies": [ { "id": "ball", "mode": "dynamic", "position": [0, 600, 0], "rotation": [0, 0, 0, 1], "shape": { "kind": "sphere", "radius": 40 }, "mass": 0.2, "friction": 0.5, "restitution": 0.6, "linearDamping": 0, "angularDamping": 0, "linearVelocity": [0, 0, 0], "angularVelocity": [0, 0, 0] } ], "impulses": [] } } } [Response | json] { "project": { "id": "ball-drop", "revision": 4, "name": "Ball drop" }, "projectUrl": "https://puni.design/p/ball-drop" } ``` ## `puni_render_view` Supply and retain `requestId` before drawing. To recover its original PNG after a lost response, failed local write, or later project edit, send `recoverOnly: true` and that ID (with the project `id`). Recovery ignores the current revision, returns only the owner’s retained receipt, and never reserves or draws another render. Receipts expire after about a day; terminal IDs persist. Missing or expired receipts refuse with `RENDER_ALREADY_ENDED`, and pending attempts with `RENDER_IN_FLIGHT`. The installed CLI uses `--recover ` for this path. See a saved revision as the studio draws it, or that revision with a command batch applied and nothing saved: a PNG rendered on Puni's render worker. This is the picture that evaluation is not, and the way to look before you write. ### Arguments for `puni_render_view` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The scene. | | `recoverOnly` | `boolean` | With requestId, return only the owner-scoped retained receipt. Independent of the current revision; never reserves or draws again. | | `reuseResult` | `boolean` | Reuse an identical still-valid receipt for free and bind requestId to those bytes for recovery. Expired or missing bytes start a fresh attempt; recoverOnly never does. | | `requestId` | `string` | The ID for one render attempt, 1 to 100 letters, digits, underscores or hyphens, starting with a letter or digit. Reuse it with identical input after a lost response. Use a new ID after a confirmed failure. | | `revision` | `integer` | The saved revision to draw; the current one when left out. | | `commandsJson` | `string` | A command batch to apply before drawing, saving nothing: what the edit would look like. | | `batchId` | `string` | A batch sent once with stage_commands, to draw instead of commandsJson. Not both. | | `environment` | `object` | Stage fields to draw with, as update_scene takes them, saving nothing. | | `environment.lighting` | `soft \| gallery \| dark` | soft, gallery or dark. | | `environment.exposure` | `number` | Exposure, 0.1 to 3. | | `environment.shadows` | `boolean` | Whether objects cast shadows. | | `environment.background` | `string` | A six-digit colour, #rrggbb. | | `environment.transparent` | `boolean` | Draw without a background or floor. | | `time` | `number` | The time to draw, in seconds, inside the duration. Default 0. | | `camera` | `orbit \| shot \| perspective \| front \| top \| side` | orbit for the fitted view, shot for the authored cameras, or a side to fit from: perspective, front, top, side. | | `width` | `integer` | Width in pixels, 64 to 1024. Default 640; height follows the frame. | - Needs the render scope. The picture comes back in the result as a PNG the client can show; a render too large to return asks for a smaller width. - With requestId omitted, retained results are reused for identical input. A draw already in progress is refused; a refunded failure can be tried again. ### Result from `puni_render_view` Returns the PNG in an MCP image content block. `structuredContent` carries the scene name, document hash, image checksum and byte count, time, camera, dimensions, render duration, the exact saved revision, and `prospective: true` when a batch or an `environment` was drawn over it. A text content block repeats that metadata. A batch that does not apply draws nothing and costs nothing: the answer is `drawn: false` with the validator's reason in `error` and the same `commandIndex`, `commandType` and `refusedWhen` that `apply_scene_commands` returns. Name a batch from `stage_commands` by `batchId` instead of `commandsJson` to draw it, then apply the same `batchId` without sending the JSON again. Compatible MCP Apps hosts can display Puni's image viewer. Download support depends on the host. Receiving image content as an agent does not prove the person can see it. `imageResource` identifies the embedded bytes; it is not a public download URL. Ask for a smaller width if the result is too large. Needs `render`. ### Call and response for `puni_render_view` The response excerpt omits the repeated text block and abbreviates image data and hashes. ```tabs [Call | json] { "tool": "puni_render_view", "arguments": { "id": "quiet-guest", "revision": 8, "time": 1, "camera": "shot", "width": 640 } } [Response excerpt | json] { "content": [ { "type": "image", "mimeType": "image/png", "data": "iVBORw0KGgo…" } ], "structuredContent": { "name": "Quiet guest", "documentHash": "5b7d…", "imageSha256": "a281…", "imageBytes": 38421, "imageResource": "puni://render/a281….png", "time": 1, "camera": "shot", "renderMs": 1840, "width": 640, "height": 640, "identity": { "projectId": "quiet-guest", "revision": 8 }, "resource": "puni://project/quiet-guest/8" } } ``` ## `puni_compare_reference` Render a saved revision and measure how close it stands to a reference picture you supply: silhouette, structure, proportion, and colour overall and region by region. `reference` accepts inline base64, an owner-scoped `/api/assets/` URI returned by `upload_asset`, or a public HTTPS image URL. Original bytes must be PNG, JPEG or WebP and at most 4 MiB. URL intake has an eight-second deadline and at most three redirects; every resolved address and redirect must remain public (no private, loopback, link-local or reserved addresses). The connection is pinned to a checked address. Image bytes, never response headers or URL suffixes, determine the format. An unavailable asset on this account is refused without reading another owner's assets. The measurement frame uses a transparent environment and the subject's alpha mask, not its colour. This removes the floor and its shadow; it does not alter the saved environment. The card includes `measurement: { background: "transparent", subjectMask: "alpha", includesFloor: false }`. The terminal's `puni render compare --reference ` uses the same cutout pipeline; its reference input remains a local file. ### Arguments for `puni_compare_reference` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The scene. | | `requestId` | `string` | The ID for one comparison attempt, 1 to 100 letters, digits, underscores or hyphens, starting with a letter or digit. Reuse it with identical input after a lost response. Use a new ID after a confirmed failure. | | `revision` | `integer` | The saved revision to draw. Default the current one. | | `time` | `number` | The time to draw, in seconds. Default 0. | | `reference` required | `string` | A PNG or JPEG of the thing the scene should look like, base64 encoded, under 4 MB. | - Needs the render scope. Likeness below the 0.85 floor is a mechanics milestone, not a proof of resemblance. A render or reference with no subject is refused (LIKENESS_RENDER_EMPTY, LIKENESS_REFERENCE_EMPTY), not scored. - With requestId omitted, retained results are reused for identical input. A draw already in progress is refused; a refunded failure can be tried again. ### Result from `puni_compare_reference` Returns the rendered PNG in an MCP image content block. `structuredContent` carries `likeness`, `structure`, the `floor` of 0.85, whether it `passes`, a `verdict`, `proportion`, `aspect`, `colour` and `placement` scores, the document hash, render duration and exact scene identity. A text block repeats that metadata. A score under the floor means the build is not yet the thing, and so does colour that is wrong on both of its terms, overall or where it sits. A render with no subject is refused with `LIKENESS_RENDER_EMPTY` and a reference with none with `LIKENESS_REFERENCE_EMPTY`, before any score. Needs `render`. ### Call and response for `puni_compare_reference` The response excerpt shows the metadata; image content and its repeated text block are omitted. The input image and document hash are abbreviated. ```tabs [Call | json] { "tool": "puni_compare_reference", "arguments": { "id": "quiet-guest", "revision": 8, "time": 0, "reference": "/9j/4AAQSkZJRgABAQ…" } } [Response excerpt | json] { "structuredContent": { "likeness": 0.91, "structure": 0.64, "floor": 0.85, "passes": true, "verdict": "above the floor: eyes rule", "proportion": 0.93, "aspect": { "puni": 0.56, "ref": 0.6 }, "colour": { "shared": 0.71, "meanGap": 0.04 }, "placement": { "shared": 0.66, "meanGap": 0.05 }, "documentHash": "5b7d…", "renderMs": 1920, "identity": { "projectId": "quiet-guest", "revision": 8 } } } ``` ## `puni_render_film` Start a background, silent H.264 film of a saved revision with `render` access. The tool returns a job handle without waiting for encoding. Hosted intake must be enabled by the deployment; `FILM_SERVICE_UNCONFIGURED` means it is unavailable. Where the studio offers **Film** on the same service, its Export lists the scene's films of the last day, so the owner can see and download a film you made. ### Arguments for `puni_render_film` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The scene to film. | | `revision` | `integer` | The saved revision to film. Leave it out for the current one. | | `requestId` required | `string` | Names this film. Repeat it to recover the same job after a lost answer; a new film needs a new requestId. | | `fps` | `integer` | Frames per second, 1–60. Defaults to 30 or the scene's own rate if lower. | | `width` | `integer` | An even width from 64 to 1280 pixels; height follows the scene's frame. Defaults to 640. | | `start` | `number` | Seconds into the scene to begin. Defaults to 0. | | `duration` | `number` | Seconds to film, at most 30. Defaults to the scene's length up to 8 seconds. | | `recoverOnly` | `boolean` | Only read the job named by requestId; never starts or charges a film. | - Needs the render scope. Starts a background film and returns at once; repeat the same requestId with recoverOnly: true to poll. FILM_SERVICE_UNCONFIGURED means hosted films are not enabled on this deployment. ### Result from `puni_render_film` Retain the scene `id` and your `requestId`. Poll with those values and `recoverOnly: true`; polling never starts another job or charge. Repeating a start with the same ID recovers its retained source and settings. Changing explicit settings under that ID is refused. The handle reports `queued`, `rendering`, `encoding`, then `completed`, `failed` or `cancelled`; an active cancellation can report `cancelling`. A completed result includes an `assetUri` and an authenticated `download` descriptor. Read its metadata and chunks, concatenate them in order, and verify the byte count and SHA-256 before retaining the MP4. Downloads expire after 24 hours. Films use the saved shot camera, or the orbit camera when no shot is authored. Duration is at most 30 seconds, with at most 1800 frames. Failed or cancelled jobs refund their hosted-render allowance. Recovery never relaunches a failed job; a deliberately new attempt needs a new request ID. ### Call and response for `puni_render_film` This example assumes hosted intake is enabled. The response excerpt omits settings and expiry. ```tabs [Call | json] { "tool": "puni_render_film", "arguments": { "id": "quiet-guest", "revision": 8, "requestId": "quiet-guest-film-1", "width": 256, "fps": 2, "duration": 1 } } [Response excerpt | json] { "id": "quiet-guest-film-1", "requestId": "quiet-guest-film-1", "revision": 8, "status": "queued", "progress": 0 } ``` ## `sculpt_object` Turn one picture or a prompt into a textured mesh, on your own provider keys from **Settings → Providers**, or on Puni credits where platform generation is enabled. ### Arguments for `sculpt_object` | Argument | Type | What it does | | --- | --- | --- | | `requestId` | `string` | A stable ID for this sculpt; reuse it with identical input after a lost response and it returns the same attempt. | | `name` required | `string` | Name the sculpt, up to 80 characters. | | `image` | `string` | One picture as base64. Choose exactly one of image, imageUrl or prompt. | | `imageUrl` | `string` | A public HTTPS picture URL. Choose exactly one input. | | `prompt` | `string` | Describe an object in up to 4,000 characters; makes a transparent picture using your OpenAI key before sculpting it. Use this from ChatGPT web. | | `lip` | `keep \| strip` | strip erases a sticker outline; keep preserves it. Prompts default to keep, pictures to strip. | | `faces` | `integer` | Provider mesh target, 40,000 to 500,000 faces. | | `generateType` | `Normal \| Geometry` | Normal makes a textured mesh; Geometry makes untextured geometry. Defaults to Normal. | | `views` | `object` | Separate views of the same object, proportions and pose. Requires a front image or imageUrl, not a prompt. | | `views.back` | `object` | The back reference, with exactly one of image or imageUrl. | | `views.back.image` | `string` | Base64 PNG, JPEG or WebP under 12 MB. Request-wide transport limits also apply. | | `views.back.imageUrl` | `string` | A public HTTPS image URL, fetched with the same network and size guards as the front. | | `views.back.mime` | `image/png \| image/jpeg \| image/webp` | MIME type of this base64 image: image/png, image/jpeg or image/webp. | | `views.left` | `object` | The left reference, with exactly one of image or imageUrl. | | `views.left.image` | `string` | Base64 PNG, JPEG or WebP under 12 MB. Request-wide transport limits also apply. | | `views.left.imageUrl` | `string` | A public HTTPS image URL, fetched with the same network and size guards as the front. | | `views.left.mime` | `image/png \| image/jpeg \| image/webp` | MIME type of this base64 image: image/png, image/jpeg or image/webp. | | `views.right` | `object` | The right reference, with exactly one of image or imageUrl. | | `views.right.image` | `string` | Base64 PNG, JPEG or WebP under 12 MB. Request-wide transport limits also apply. | | `views.right.imageUrl` | `string` | A public HTTPS image URL, fetched with the same network and size guards as the front. | | `views.right.mime` | `image/png \| image/jpeg \| image/webp` | MIME type of this base64 image: image/png, image/jpeg or image/webp. | | `views.top` | `object` | The top reference, with exactly one of image or imageUrl. | | `views.top.image` | `string` | Base64 PNG, JPEG or WebP under 12 MB. Request-wide transport limits also apply. | | `views.top.imageUrl` | `string` | A public HTTPS image URL, fetched with the same network and size guards as the front. | | `views.top.mime` | `image/png \| image/jpeg \| image/webp` | MIME type of this base64 image: image/png, image/jpeg or image/webp. | | `views.bottom` | `object` | The bottom reference, with exactly one of image or imageUrl. | | `views.bottom.image` | `string` | Base64 PNG, JPEG or WebP under 12 MB.

Choose Read, write and sculpt or Full access when connecting. ### Result from `sculpt_object` Returns the new sculpt's `id` and its `status`. A prompt makes a picture first with your OpenAI key, then the mesh with your fal key (or both on Puni credits). Poll `get_sculpt` for progress; the model call is paid with your keys or your credits. Needs `sculpt`, even with your own provider keys. ### Call and response for `sculpt_object` ```tabs [Call | json] { "tool": "sculpt_object", "arguments": { "name": "Felt red panda", "prompt": "a small felt red panda plush, sitting" } } [Response | json] { "id": "sculpt-3f1c", "status": "sculpting", "name": "Felt red panda" } ``` ## `get_sculpt` Read a sculpt's progress. Each read moves it along; when it is ready the result carries the source and the commands that put it in a scene. ### Arguments for `get_sculpt` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The sculpt id returned by sculpt_object. | ### Result from `get_sculpt` Returns `status`, and when ready the stored `source` (a GLB), the ingest figures, and `add`: the `add-module`, `add-instance` and `add-track` commands for `apply_scene_commands` that place it in a scene at its original size. ### Call and response for `get_sculpt` ```tabs [Call | json] { "tool": "get_sculpt", "arguments": { "id": "sculpt-3f1c" } } [Response | json] { "id": "sculpt-3f1c", "status": "ready", "source": { "kind": "glb", "uri": "/api/assets/9c4e…", "sha256": "9c4e…" }, "ingest": { "triangles": 184320, "bytes": 5242880 }, "add": [ { "type": "add-module", "module": { "id": "sculpt-3f1c", "adapter": "source" } } ] } ``` ## `segment_sculpt` Split a ready sculpt into named parts that keep their textures. About two minutes and one more paid model call; call again to re-roll. ### Arguments for `segment_sculpt` | Argument | Type | What it does | | --- | --- | --- | | `id` required | `string` | The id of a ready sculpt, as returned by sculpt_object. | | `requestId` | `string` | A stable ID for this split; reuse it after a lost response and it returns the same attempt. | - Needs sculpt to start a paid split. Poll the existing sculpt with get_sculpt using scene:write. ### Result from `segment_sculpt` Returns the sculpt with `status` back to working. Poll `get_sculpt`; when ready, `addSegmented` carries the commands for the segmented source, and the previous source stays available. Needs `sculpt`, even with your own provider keys. ### Call and response for `segment_sculpt` ```tabs [Call | json] { "tool": "segment_sculpt", "arguments": { "id": "sculpt-3f1c" } } [Response | json] { "id": "sculpt-3f1c", "status": "segmenting" } ``` ## Resources The server also lists your scenes as resources. `puni://project/{id}/{revision}` returns the whole document; add `/chunks/{index}` for a large one in pieces. `puni://contract/commands` and `puni://contract/types` return the contract text.

They live at `https://puni.design/api` and answer JSON. Prefer the [command line](https://puni.design/docs/developers/cli) or the [MCP tools](https://puni.design/docs/developers/mcp-tools) when one fits; the routes are here for the cases they do not cover. ## Signing requests Send a token as a bearer: `Authorization: Bearer puni_access_…`. Tokens from Settings, from the command line's sign-in and from the OAuth door are the same kind. The route exchanges one for a short session on every call. The browser signs in with its own session cookie. ## Scenes | Route | Method | Does | | --- | --- | --- | | `/api/projects` | GET, POST | List your scenes; create one from a document | | `/api/projects/{id}` | GET, PATCH | Read a scene with its revision (`?metadata=1` for its summary and `documentUrl`); rename or archive | | `/api/projects/{id}/checkpoints` | GET, POST | List checkpoints; keep one now | | `/api/projects/{id}/cover` | POST | Set the cover for a saved document hash | | `/api/projects/{id}/shares` | GET, POST | List links; make one for a revision | | `/api/projects/transfers` | POST | Begin and finish a scene upload | | `/api/assets` | POST | Upload a small asset inline | | `/api/assets/transfers` | POST | Begin and finish a direct asset upload | | `/api/assets/{id}` | GET | Read an asset you own | Writes carry the revision they expect. A stale revision answers `409`. ## Links | Route | Method | Does | | --- | --- | --- | | `/api/share/{id}` | GET | The link's public metadata | | `/api/share/{id}/document` | GET | The saved document the link points at | | `/api/share/{id}/assets/{hash}` | GET | An asset that document references | | `/api/share/{id}/copy` | POST | Remix into the caller's library | | `/api/share/{id}/view` | POST | Count a view, once per session | ## Devices and agents | Route | Method | Does | | --- | --- | --- | | `/api/device/connect`, `exchange`, `session`, `revoke` | POST | The sign-in flow the command line runs | | `/api/device/status`, `sessions` | GET | A pending code; your connected devices | | `/.well-known/oauth-protected-resource`, `oauth-authorization-server` | GET | How a connector finds the sign-in door | | `/api/oauth/authorize` | GET | Start connector authorization; consent is a Puni page | | `/api/oauth/register`, `token`, `revoke` | POST | Register a client, exchange a grant, or revoke access | | `/api/agent/turns` | GET, POST | List turns with `?projectId={id}`, or deliver one for a revision; no connected runner returns PUNI_RUNNER_REQUIRED | | `/api/agent/turns?turnId={id}` | GET | One turn with its events | | `/api/agent/turns/{id}/cancel` | POST | Stop a turn; edits already saved remain | | `/api/projects/{id}` | PATCH | Land one command batch on the revision you read, with a label; the scene keeps a checkpoint | | `/api/agent/runner` | GET, POST | Read presence; register or unregister a connected runner | | `/api/agent/runner/turns` | GET | List the signed-in owner's runner-delivered turns | | `/api/agent/runner/turns/[id]` | POST | Claim, heartbeat, complete, fail or release a turn with its runner capability | | `/api/mcp` | GET, POST, DELETE | The MCP server | ## Search, films, runtime | Route | Method | Does | | --- | --- | --- | | `/api/library/search` | POST | Keyword or semantic search of your scenes | | `/api/films/*` | GET, POST | Film job uploads and downloads, when enabled | | `/api/runtime` | GET | The app's builds, for `puni runtime` | ## Errors Product errors use JSON with an `error` sentence to show. A catalogued refusal adds a `code` to branch on and its `detail`, such as the revision a 409 conflict is now at. A 409 also carries `conflict: true`. A server fault answers 5xx with a code too, such as `BACKEND_UNAVAILABLE`, so a client knows to retry rather than change its request. The OpenAPI document lists every code and every status a refusal can answer with, including 422, 502 and 504. OAuth errors use `error` and may include `error_description`. Limits: a scene document is 32 MB and an asset 64 MB. Ordinary MCP requests are capped at 768,000 bytes. `upload_asset` admits a larger base64 envelope for up to 8 MiB of decoded bytes; SVG retains its 2 MiB format cap. `puni_compare_reference` also admits a larger envelope for its bounded image input. Hosting proxies can impose smaller limits. Inline scene and asset API transfers have a 4 MB budget. These transfer limits are separate from the MCP upload exception. Save a larger scene through `/api/projects/transfers` and upload a larger asset through `/api/assets/transfers`. A saved scene or checkpoint larger than that is refused inline with `SCENE_READ_BY_URL`: read it with `?metadata=1`, download the `documentUrl` it names, and check the bytes against its `sha256`. ## OpenAPI `https://puni.design/api/openapi.json` describes every route above as OpenAPI 3.1, generated from the routes and kept honest by a test. Point a client generator or an agent framework at it when neither MCP nor the command line fits.

Replies that complete are cached by request ID (the last 64), so a retry of the same body cannot apply twice; rate-limit, schema, `not_ready`, `reduced_motion` and `hidden` failures are not cached, so a retry re-executes; a different body under the same ID fails with `request_conflict`. Expect `invalid_request`, `invalid_operation`, `request_conflict`, `stale_request`, `stale_channel`, `not_ready`, `rate_limited`, `reduced_motion` and `hidden`. Only unlocked, visible top-level objects and their ordinary properties are exposed. There is no path from a host page to commands, selection, assets, or your account.

An agent driving that browser gets the signed-in session for free: no token, no server, the scene that is open. ## Tools on the landing page | Tool | Does | | --- | --- | | `puni_get_started` | Where the person signs in to begin; it does not sign in or open anything | | `puni_read_contract`, `puni_read_runtime` | The command contract; the app's builds | ## Tools on the library | Tool | Does | | --- | --- | | `puni_list_projects` | Your scenes with their revisions | | `puni_open_project` | Opens one in the studio | | `puni_create_composition` | A new blank scene, saved and opened | | `puni_search_projects` | Keyword search, or semantic with `mode: "semantic"` | | `puni_read_contract`, `puni_read_runtime` | The command contract; the app's builds | | `puni_read_project` | A saved scene's structure at the revision search returned | | `puni_preview_scene_index`, `puni_index_scene_description` | What semantic search would send, then sending it on request | | `puni_remove_scene_embedding`, `puni_refresh_scene_search` | Remove a scene from semantic search; bring its entry up to date | The search and index tools are on the studio too. Project summaries use `actionCount` for action definitions and `clipCount` for timeline clips. Legacy stored metadata has `actionCount: null` until resaved; counts from a loaded document are exact. Checkpoint `actions` aliases `actionCount`. ## Tools in the studio | Tool | Does | | --- | --- | | `puni_read_scene` | The open scene's document, selection, playhead time and save state | | `puni_select_objects`, `puni_seek_timeline` | Selection and time, the way a pointer would | | `puni_apply_command` | One validated, undoable authoring command, saved at once | | `puni_history` | Undo or redo the latest edit, then save | | `puni_inspect_construction`, `puni_save_construction_motion` | Take a structured object apart for inspection; keep that as timeline motion | | `puni_save_object`, `puni_use_object` | Keep a selection as a library object; bring one into this scene | | `puni_export_composition` | The scene as a project file, a GLB or a PNG | | `puni_read_viewer` | What the page is drawing: its load state, frame rate, draw calls and GPU resources | | `puni_sculpt_object` | A front picture (an https URL) with optional extra views, or a prompt, into an object; on the person's own keys, or Puni's credits where offered | | `puni_get_sculpt`, `puni_add_sculpt` | Progress and the add commands; or add the ready sculpt to the open scene | | `puni_segment_sculpt` | Split a ready sculpt into named parts, textures kept | ## When the tools arrive A page's own tools register as soon as it mounts. Six retrieval tools load separately and register a moment later, on the library and in the studio alike: `puni_search_projects`, `puni_read_project`, `puni_preview_scene_index`, `puni_index_scene_description`, `puni_remove_scene_embedding` and `puni_refresh_scene_search`. An agent that lists tools the instant a page opens can see the page's tools without those six; list again. If the six fail to load, the page tries once more after two seconds. If they are still missing it says so once in the console, the page's other tools keep working, and reloading the page brings them back. Leaving a page unregisters every tool it registered. ## The loop 1. `puni_read_scene` and `puni_read_contract`. 2. `puni_apply_command` for each edit (its fields are in `puni_read_contract`). It is immediate and saved, the way a pointer's edit is, and `puni_history` undoes it. 3. `puni_read_scene` again, and `puni_read_viewer` for what the page is drawing. There is nothing to commit: each edit saves a new revision. Undo it with `puni_history`, because a browser edit over browser work leaves no checkpoint. To look at pixels before writing, call `puni_render_view` from [MCP tools](https://puni.design/docs/developers/mcp-tools) with a `commandsJson` batch: it draws the saved revision with the batch applied and saves nothing. ## Brand type and geometry Upload fonts and images through the [MCP `upload_asset` tool](https://puni.design/docs/developers/mcp-tools). The browser tools do not expose that upload call. They can apply a text module with the retained font in `module.assets` and its URI in `fontAsset`. Record provenance, including the licence. Leave `fontAsset` absent to keep the built-in typeface. Missing or invalid custom font bytes refuse without substitution. A profile can use exact SVG path data in its outline, with inset `bevel` and `bevelSegments` for its edge. If an older module rejects a new property, update its definition from the current contract first. ## The browser must draw `puni_read_viewer` answers with what the page has drawn, and drawing needs WebGL. Some hosted browsers, ChatGPT's among them, have no WebGL. There the viewer reports an error and never a drawn scene, so builds are blind. Read [How agents see](https://puni.design/docs/agents/how-agents-see). ## Limits Leaving the scene unregisters the tools. Read [MCP tools](https://puni.design/docs/developers/mcp-tools) for the same loop from outside the browser. --- Source: https://puni.design/docs/developers/cli Raw Markdown: https://puni.design/docs/developers/cli.md --- description: >- Every command group in puni, the flags they share, how remote commands name their origin, and where the exit codes are. figure: null group: Reference navTitle: Command line icon: null order: 30 redirects: - /cli-reference sourceRefs: - apps/cli/src/operations.ts - apps/cli/src/main.ts - docs/cli.md status: preview surfaces: - terminal title: Command line verifiedAt: '2026-10-11' --- The command line is a preview for Puni's own team. It builds from Puni's private repository and is not published to npm, so you can run it only with access to that repository. An agent reaches your library without it through [Connect Puni](https://puni.design/docs/agents/connect). `puni` prints a readable answer by default. With `--json`, commands return one JSON envelope except `agent serve`, which streams lifecycle records before its final envelope. Start with the [Quickstart](https://puni.design/docs/developers/quickstart) if this is your first session, or [Setup](https://puni.design/docs/developers/setup) for requirements, credentials and exit codes. ## Find a command ```bash puni --help ``` | Group | Reference | | --- | --- | | Local scenes | [scene](https://puni.design/docs/developers/cli-scene), [checkpoint](https://puni.design/docs/developers/cli-checkpoint), [interface](https://puni.design/docs/developers/cli-interface), [studies](https://puni.design/docs/developers/cli-studies), [contract](https://puni.design/docs/developers/cli-contract) | | Drawing and making | [render](https://puni.design/docs/developers/cli-render), [renderer](https://puni.design/docs/developers/cli-renderer), [sculpt](https://puni.design/docs/developers/cli-sculpt) | | Your library | [auth](https://puni.design/docs/developers/cli-auth), [project](https://puni.design/docs/developers/cli-project), [search](https://puni.design/docs/developers/cli-search), [runtime](https://puni.design/docs/developers/cli-runtime) | | Agents | [agent](https://puni.design/docs/developers/cli-agent) | | Mono | [mono](https://puni.design/docs/developers/cli-mono) | ## Common flags ```bash puni project list --base-url https://puni.design puni project list --base-url https://puni.design --json ``` `--json` gives one `{ "data", "meta" }` object on success or one `{ "error" }` object on failure. `agent serve --json` is the exception: parse stdout one line at a time as NDJSON, with raw lifecycle records followed by the final envelope. See [Agent commands](https://puni.design/docs/developers/cli-agent#agent-serve). `--help` prints the whole command list. File inputs accept `-` for standard input, once per command. ## Remote commands Every command that talks to your library takes `--base-url https://puni.design`. Writes name the revision they expect with `--revision N` and are refused if the library moved on. Tokens come from `puni auth login`, `PUNI_AUTH_TOKEN`, or `--auth-file`. ## Files Commands that write a file take `--output`. Replacing an existing file needs `--overwrite`. Writes are prepared and checked before the file is published, so a failure never leaves a half-written scene.

Read [Rendering](https://puni.design/docs/make/rendering) for the three tiers. With no browser installed, a render in a terminal offers once to download Chromium into Puni's own cache (`PUNI_BROWSERS_PATH`, else `$XDG_CACHE_HOME/puni/browsers`, else `~/.cache/puni/browsers`), naming what it costs on disk. `--yes` accepts without asking. A run that is not interactive, or has `CI` set, or asked for `--json`, is never asked and fails exactly as it did before, unless `--yes` is given, which downloads without asking in any of these cases. A refusal is remembered only for that run. A browser you name yourself, with `--browser` or the host's own variable, is an instruction: if that path is empty the render says so rather than fetching something else. `puni render` Draw a scene file with the studio's own renderer: a PNG, a GLB, a USDZ, or a film. | Command | What it does | | --- | --- | | `puni render png` | A still. Samples 0 is the studio raster; 1 to 1024 is the path tracer. | | `puni render glb` | The sampled scene as glTF with materials, part IDs and interface textures, in metres. | | `puni render usdz` | The sampled scene for RealityKit. | | `puni render view` | The still render png draws, made by a render worker instead of this machine. For a machine with no GPU, or none the caller may use. With --id it asks Puni's hosted renderer to draw a saved project through the same puni_render_view tool a connector calls: that picture is metered like a connector's render and needs a token with the render scope ("Read, write and render" in Settings → Agents). Local renders (render png\|glb\|usdz\|film) are never metered. | | `puni render compare` | Judge a scene against a reference picture. It renders the scene the way render png does, then scores the pair with the same likeness card the hosted puni_compare_reference tool reports, so one pair reads the same through both doors. A read: nothing is saved. The floor is a gate, not a verdict — above it the eyes rule, below it the work is a mechanics milestone. A pass also needs the colour inside the outline, overall and region by region, not to be wrong on both of its terms at once. A render or reference with no subject is refused with LIKENESS_RENDER_EMPTY or LIKENESS_REFERENCE_EMPTY and exit 2, never scored. | | `puni render film` | Every frame from zero, with the scene's sound, encoded by the local renderer.

For a machine with no GPU, or none the caller may use. Usage: `puni render view (--file scene.json | --id PROJECT) --output view.png --remote [--revision N] [--request-id ID | --recover ID] [--time 0] [--width 640]` | Flag | Type | Default | Values | What it does | | --- | --- | --- | --- | --- | | `--file` | `string` | | | The scene or portable file. Or name a saved project with --id. | | `--id` | `string` | | | A saved project ID, drawn by Puni's hosted renderer and metered. Cannot be combined with --file. | | `--output` required | `string` | | | Where to write the PNG. | | `--remote` required | `boolean` | `false` | | Required: with --file, ask the render worker named by PUNI_RENDER_WORKER_URL and PUNI_RENDER_WORKER_SECRET; with --id, ask the studio at --base-url, PUNI_BASE_URL or the one saved sign-in. | | `--revision` | `number` | | | With --id: the saved revision you expect. A scene that has moved on answers REVISION_CONFLICT (exit 75). Omit it to draw the current revision. | | `--request-id` | `string` | | | With --id: an optional stable attempt ID, 1 to 100 letters, digits, - or _, starting with a letter or digit. Otherwise the CLI generates an ID. Recover its retained receipt with --recover ID after a failure. | | `--recover` | `string` | | | With --id: retrieve an owner's retained receipt by attempt ID, even after an edit. Returns the original bytes or refuses without charging or drawing again. | | `--time` | `number` | `0` | | Scene time to sample, in seconds, inside the duration. | | `--width` | `number` | `640` | | Output width in pixels, 64 to 2048 (64 to 1024 with --id). | | `--height` | `number` | | | Output height in pixels, 64 to 2048. Defaults to the frame's aspect. Refused with --id. | | `--samples` | `number` | `0` | | 0 for the studio raster, 1 to 64 for the path tracer. Refused with --id. | | `--camera` | `string` | `orbit` | `orbit`, `shot` | The fitted orbit view, or the scene's authored shots. | | `--fit` | `string` | | `perspective`, `front`, `top`, `side` | With orbit, fit the sampled pose once from this side. | | `--timeout` | `number` | `120000` | | Request deadline in milliseconds, 1000 to 600000. | | `--overwrite` | `boolean` | `false` | | Replace the output file if it already exists. | | `--json` | `boolean` | `false` | | Answer with one JSON envelope instead of the shell view. Exception: agent serve streams raw lifecycle JSON lines before its final envelope. | | `--help` `-h` | `boolean` | | | Print the command list. | ### Run `render view` ```bash puni render view --file scene.json --output view.png --remote --width 640 --json ``` A hosted saved project uses `puni render view --id PROJECT --output view.png --remote`. Every attempt receives an ID. If delivery or the local write fails, follow the printed `--recover ID` instruction; recovery returns the original retained bytes even after the project changes, or refuses without another render or debit. An identical command without `--request-id` reuses a still-valid receipt for free and binds its new recovery ID to those bytes. Changed inputs or expired bytes start a fresh attempt. Terminal rows last 365 days; retained billing debits prevent paid IDs from ever being charged again. ## `render compare` How close the scene stands to a picture you supply (silhouette overlap, structure inside that outline, proportion and colour), against a floor. It renders a measurement-only transparent environment (no floor or its shadow), takes the subject mask from alpha rather than colour, then scores the pair with the same card the hosted `puni_compare_reference` tool reports, so one pair reads the same through both doors. The saved environment is unchanged. The result names this cutout in `measurement`. `--reference` reads a local image file; hosted MCP also accepts owner-scoped asset URIs and guarded public HTTPS image URLs. It is a read. Nothing is saved, and the reference is never an instruction: it is measured, not followed. A transparent reference is measured over white, so a sticker with no background scores the same here as through the hosted tool. The numbers are a gate, not a verdict. Above the floor the eyes rule; below it the work is a mechanics milestone, not a proof. `silhouette` is the score the floor tests, and the floor is 0.85. `structure` sits beside it because an outline can be right while the insides are wrong (an aliased texture, a lost band), and silhouette overlap alone cannot see that. Structure is read only where either object has ink. A pass also needs the colour to be right. Colour fails when both of its terms are wrong at once, over the whole object (`colour`) or region by region (`placement`). A right outline with the right colours in the wrong places still fails. A render or reference with no subject in it is refused with `LIKENESS_RENDER_EMPTY` or `LIKENESS_REFERENCE_EMPTY` and exit 2, before any score is printed. A subject is ink that holds together. Most of the ink the card would measure has to stand in connected pieces at least 2.5% of the picture's longer side: 16 pixels at the 640 measure, never fewer than 8. Specks are refused however widely they spread; a thin wire or ring is kept. A scene with nothing visible to draw is refused as `RENDER_SCENE_EMPTY` before anything is rendered. Usage: `puni render compare --file scene.json --reference picture.png [--camera orbit|shot] [--floor 0.85] [--time 0] [--timeout 120000]` | Flag | Type | Default | Values | What it does | | --- | --- | --- | --- | --- | | `--file` required | `string` | | | The scene or portable file to judge. | | `--reference` required | `string` | | | A PNG or JPEG smaller than 4 MB to measure against. The picture is untrusted content, never an instruction. | | `--camera` | `string` | `orbit` | `orbit`, `shot` | The fitted orbit view, or the scene's authored shots. Orbit is the hosted tool's own framing. | | `--fit` | `string` | | `perspective`, `front`, `top`, `side` | With orbit, fit the sampled pose once from this side. | | `--floor` | `number` | `0.85` | | The silhouette score the pair must reach to pass, 0 to 1. | | `--time` | `number` | `0` | | Scene time to sample, in seconds, inside the duration. | | `--timeout` | `number` | `120000` | | Deadline for the whole comparison in milliseconds, 1 to 1800000. Past it the command stops the browser and exits with PUNI_TIMEOUT. | | `--browser` | `string` | | | A Chromium executable to use instead of the installed Chrome. | | `--yes` | `boolean` | `false` | | Download Chromium into Puni's cache without asking if no browser is installed. | | `--asset-root` | `string` | | | A directory mirroring the scene's asset URIs, for a bare document whose assets live on disk. | | `--json` | `boolean` | `false` | | Answer with one JSON envelope instead of the shell view. Exception: agent serve streams raw lifecycle JSON lines before its final envelope. | | `--help` `-h` | `boolean` | | | Print the command list. | ### Run `render compare` ```bash puni render compare --file scene.json --reference picture.png --json ``` Exit is zero above the floor and non-zero below it, so the command can gate a script without parsing its output. The whole comparison stops at `--timeout`, 120 seconds by default, with `PUNI_TIMEOUT`. The deadline starts before the first file is read, so a stalled reference, scene or runtime read is held to it too. An interrupt stops it with `PUNI_CANCELLED`. Either way the browser it started is closed, and a browser that has not closed five seconds later is killed. ## `render film` Every frame from zero, with the scene's sound, encoded by the local renderer. Usage: `puni render film --file scene.puni.json --output scene.mp4 [--width 640 --height 640] [--duration 2 --fps 12]` | Flag | Type | Default | Values | What it does | | --- | --- | --- | --- | --- | | `--file` required | `string` | | | The scene or portable file. | | `--output` required | `string` | | | Where to write the MP4. | | `--duration` | `number` | | | A prefix of the scene in seconds, up to 300. | | `--fps` | `number` | | | Frames per second, 1 to 120. Defaults to the frame. | | `--bridge-url` | `string` | `http://127.0.0.1:4317` | | The local renderer's loopback origin. | | `--time` | `number` | `0` | | Film always starts at zero; the value must be 0 or omitted. | | `--width` | `number` | | | Output width in pixels, 64 to 4096. Defaults to the frame. | | `--height` | `number` | | | Output height in pixels, 64 to 4096. Defaults to the frame. | | `--camera` | `string` | `orbit` | `orbit`, `shot` | The fitted orbit view, or the scene's authored shots. | | `--fit` | `string` | | `perspective`, `front`, `top`, `side` | With orbit, fit the sampled pose once from this side. | | `--browser` | `string` | | | A Chromium executable to use instead of the installed Chrome. | | `--yes` | `boolean` | `false` | | Download Chromium into Puni's cache without asking if no browser is installed. | | `--asset-root` | `string` | | | A directory mirroring the scene's asset URIs, for a bare document whose assets live on disk. | | `--timeout` | `number` | `120000` | | Deadline for the whole operation in milliseconds, 1 to 1800000. | | `--overwrite` | `boolean` | `false` | | Replace the output file if it already exists. | | `--json` | `boolean` | `false` | | Answer with one JSON envelope instead of the shell view.

Exception: agent serve streams raw lifecycle JSON lines before its final envelope. | | `--help` `-h` | `boolean` | | | Print the command list. | ### Run `sculpt` ```bash puni sculpt --image panda.png --base-url https://puni.design ``` ### Separate reference views `--image` is the front view. Add any of `--image-back`, `--image-left`, `--image-right`, `--image-top`, `--image-bottom`, `--image-left-front` and `--image-right-front` to send separate images of the same object. They should agree on proportions and pose; a collage is still only one view. Additional views require a front image and cannot be combined with `--prompt`. ```bash puni sculpt --image blobby-front.png --image-back blobby-back.png \ --image-left blobby-left.png --image-left-front blobby-three-quarter.png \ --name Blobby --lip keep --generate-type Geometry --faces 120000 \ --request-id blobby-master-001 --no-wait --json ``` Use `--lip keep` for intentional silhouettes and narrow features. `strip` retains the existing sticker-outline treatment. Puni keeps each original file and the prepared PNG actually sent to the provider, with their hashes and view names in `sculpt.input.references`. The REST and MCP equivalents use `generateType: "Geometry"` and a `views` object such as `{ "back": { "imageUrl": "https://example.com/back.png" } }`. A view accepts exactly one base64 `image` (with optional `mime`) or public HTTPS `imageUrl`. Browser tools use URLs. A base64 `image` keeps the 12 MB input limit. An `imageUrl` picture must be HTTPS on the default port and at most 4 MiB. Prepared PNGs are at most 8 MB and 2048 pixels on the long side. The total request limits still apply: 4 MB for one REST call and 768 KB for MCP. Prefer image URLs whenever base64 pictures would exceed that budget. Reuse the same request ID and identical images and options after a lost response. Changing a view, mode or other generation option under that ID is refused. The default `Normal` single-image and prompt requests keep their existing retry identity. ### Provider master and delivery source `sculpt.master.source` identifies the provider's untouched GLB, retained before optimization. `sculpt.source` remains the delivery mesh, simplified toward 60,000 triangles with textures sized for scenes. These are separate references; `--output` continues to write the delivery source. Read `sculpt status ID --json` for both sources, the provider request and model, image provenance, seed when returned, and before/after ingest figures. If optimization fails after master retention, a later authorized read resumes from the stored master without another provider call or charge. Older sculpts without a retained master remain readable; their original GLBs cannot be reconstructed from their optimized files. The existing 64 MB asset limit applies to masters too. An oversized provider GLB stops before optimization and reports the limit; this capability does not increase storage limits. ## `sculpt status` Read progress, source references and faces per part.

Nothing is public unless you make a link or turn on your creator page, and both can be turned off again. [Open in Puni](https://puni.design/settings?section=security) to open these settings. ## Where things live Scene documents and their history live in Puni's database. Uploaded files, covers and shared snapshots live in Puni's storage, addressed by their content hash. Puni stores imported files so your scenes can reopen. When you ask for a sculpt or named parts, the selected picture or mesh is sent to fal for processing. Pictures made from prompts use OpenAI. These calls use your saved provider keys when present, or Puni's configured keys for credits. Semantic search sends text to Voyage when you choose it. Provider data handling depends on the provider and account used. Read [Provider keys](https://puni.design/docs/account/providers) and [Credits](https://puni.design/docs/account/credits) for costs and availability. ## Signing in Puni signs you in with an email address and a one-time code, a password, or a connected account offered on the sign-in page. **Settings → Security** lists every browser session with the device it came from. **Sign out** on a row ends that session; **Everywhere else** ends all but this one (it appears when you have more than one other session; the current one reads **This device**). ## Links A share link opens one saved version and only that version. It is unlisted: search engines are told not to index it, and there is no list of links anywhere except your own library and your creator page if you turned it on. Revoking a link stops future loads; copies already saved by a viewer stay with them. ## Devices and agents A terminal or an agent gets a token, never your password. **Settings → Devices** lists connected machines; **Settings → Agents** lists connected agents with their scope and when they were last used. **Disconnect** revokes the token at once, including any session it minted. A token can read scenes, write scenes, render pictures, make links, or start paid sculpt generation and splitting, and only what you chose when you connected it. See [Scopes and tokens](https://puni.design/docs/agents/scopes-and-tokens). ## Removing things Archive a scene to take it out of the library; its links stop working while it is archived. **Settings → Storage** shows how much of your 1 GB you hold, your biggest scenes and your archived ones. An archived scene can be deleted for good there or from its menu in the library. Its checkpoints, its films and its share links go with it; the links were already off while it was archived and are never turned back on. The space is freed at once. Imported files no other scene uses stop counting at once and are erased after 7 days; saving a scene that names one of them in that week keeps it. Deleting cannot be undone. Deleting your account (**Settings → Data**) cuts off tokens, devices, connections, share links and stored provider keys at once. Puni keeps your scenes and other data for 30 days; signing in again in that window restores them, but not tokens, links or keys. After 30 days it is permanently erased. Export anything you want to keep first. ## Password and profile Open **Settings → Security** and choose **Set** or **Change**. Enter the current password when asked, then the new password twice (at least eight characters), and choose **Save password**. An error such as “Use at least eight characters.” shows below the group. **Sign out here** ends this browser session.

Find the message you see. ## In the studio **"This browser can't draw 3D scenes: it has no WebGL."** The stage needs WebGL. Open the scene in a desktop browser with hardware acceleration turned on. Editing and saving still work; the last saved cover stands in for the picture. An agent's cloud browser usually has no WebGL: see [How agents see](https://puni.design/docs/agents/how-agents-see). **"The scene is taking a while to draw."** The load neither finished nor failed within 20 seconds. Press **Try again**. If it repeats, the browser has a WebGL context that never draws; use another browser. **"This scene was changed somewhere else. Reload to pick up the latest version."** Someone, or an agent, saved a newer revision (`REVISION_CONFLICT`). Reload the scene, then share. The share dialog’s own version reads “The open scene changed. Open sharing again.” **A blank cover on a tile.** The cover was captured by a browser that could not draw. Open the scene in a working browser and save once. ## Importing **"Scene documents must be at most 32 MB."** A `.puni.json` document is capped; asset bytes are separate. Assets inside a portable bundle do not count toward the document, but sampled motion keys can. Export from the studio again, or strip the keys and add motion in the studio. **A GLB imports but shows nothing.** Check its size. Very large meshes draw slowly. An asset is capped at 64 MB. ## Command line **`PUNI_AUTH`.** The token is missing, expired, or lacks the render scope. Sign in again with `puni auth login --base-url https://puni.design`; for the render scope, mint a token with **Read, write and render** in **Settings → Agents** instead, because signing in never grants it. Tokens last 30 days. **`PUNI_RUNTIME`.** Your command line is older or newer than the app. Rebuild it from the current checkout. **"Asset storage redirects require an explicit --asset-origin."** (`PUNI_ASSET_ORIGIN`, exit 78.) A scene with uploaded files pulls those files from storage. Pass the storage origin with `--asset-origin`. **`PUNI_CONFLICT`, exit 75.** The revision you pushed against is stale. Pull, merge your edit, push with the new revision. ## Agents **A 401 from `/api/mcp`.** The token is missing, revoked or expired. Make a new one in **Settings → Agents**. **"This connection can't edit scenes yet."** (HTTP 403 from MCP; the cover route says `Missing scope: `.) The token was made read-only. Make a new one with write. **"This result is too large."** Ask for a page of objects with `inspect_objects` instead of the whole scene, or read the document resource in chunks.

This is a Puni compatibility error, not a wrong password. No connection is ready until consent completes and the client can list your scenes.

Local Film needs Chrome and FFmpeg through the local renderer; Cycles also needs Blender. Hosted still rendering is available to connected agents where configured. See [Rendering](https://puni.design/docs/make/rendering). **Does it work on a phone?** The library, the share page and your creator page do. The studio opens on a phone with a reduced bar, and it is best on a laptop. **Can I use my own models?** Yes: GLB, SVG, pictures and LEGO models import as objects, and a portable Puni file carries a whole scene. See [Import](https://puni.design/docs/make/import). **Who can see my scenes?** Only you, until you make a link. A link is unlisted. Your creator page is off until you turn it on. **Can an agent ruin my scene?** An agent's edit lands as one saved revision with a checkpoint of the previous one, named by the agent's label. Restore the checkpoint to take it back, and a save you make while it works refuses its edit until it reads your revision. **Is Puni free?** The alpha editor is free to use. Generation using your own keys is billed by OpenAI or fal and spends no Puni credits. Where Puni's keys are available, generation spends credits. See [Credits](https://puni.design/docs/account/credits) for costs and checkout availability. ## Glossary | Term | Meaning | | --- | --- | | Scene | A saved document: objects, motion, cameras, audio, a frame and a length | | Library | Your scenes, on the home page | | Object | One thing on the stage; an instance of a module | | Module | The kind of thing an object is, and the properties it exposes | | Piece | One addressable part of an imported model | | Group | A container of objects that can drive them with one control | | Fitting | A part mounted on a body: a button, a knob, a screen, a seam | | Action | A piece of motion: keys on properties, or a procedure such as settle | | Track | An object's lane on the timeline | | Clip | An action placed on a track at a time | | Behavior | Motion that follows an object on its own clock: idle, blink, tap, hop, appear, wobble | | Response | A clip that waits for a tap | | Camera | A saved framing | | Shot | A camera placed on the timeline for a span | | Revision | One saved version of a scene | | Cover | The picture on a scene's tile and on its link | | Link | A share: one saved version, unlisted, revocable | | Remix | A copy of a shared scene in the viewer's library | | Creator page | Your live links under one handle, at `puni.design/u/handle` | | Token | What a device or an agent holds instead of your password | | Scope | What a token may do: read, write, share, render, sculpt | | Checkpoint | A saved copy of an earlier version.

Search, filters and counts cover every scene you have, and a count past a thousand reads **1000+**. **History pages through checkpoints.** **Newer checkpoints** and **Older checkpoints** at the foot of History step through a long scene's past. **Edits survive leaving.** Unsaved edits are kept when you leave a scene and are there when you come back. Escape in an inspector number field puts the old value back. **Lighting that differs.** Each Lighting preset now looks like itself, and dark clay stays readable. **Films from the studio.** Where the studio offers it, **Film** in Export draws the film on Puni's servers from the scene you saved, with no local renderer. It costs a credit where hosted renders are metered, and Export lists the scene's films from the last day. Read [Films](https://puni.design/docs/make/films). **More for agents.** Agents can send a large command batch once and name it, rename or describe a scene, and upload an asset such as a brand font for text. Where the deployment renders films, they can ask for a film of a saved revision. Key curves, pivots, opacity, outlines from SVG paths and cloner fields are in the scene document for agents and the command line; the studio has no controls for them yet. Read [MCP tools](https://puni.design/docs/developers/mcp-tools) for the full list. **Agents stay signed in.** A connected agent no longer has to sign in again after about an hour. ## September 2026 **Agents edit the saved scene.** An agent's edit lands as a new revision with a checkpoint named by the agent's label, so the checkpoint is the undo. While an agent works on a scene, its labels appear in History as they land. If you saved in the meantime, the agent's edit is refused and it reads the scene again. Drafts, which held an agent's work apart from the scene, were retired on 16 September. **A menu on the canvas.** Right-click an object for its actions and an **Animate** group; right-click empty canvas for animation presets and the Perspective, Front, Top and Side views. New actions start here. **Ask Puni is gone.** The built-in agent, its dock, **⌘J** and the library's prompt box were removed. Connect your own agent instead: read [Connect Puni](https://puni.design/docs/agents/connect). **Smoother drawing.** Where your browser supports it, the studio and share pages draw the scene off the page's main thread. Film capture in the studio needs the page itself to draw, so Film is unavailable while it does. **Deleting your account.** **Delete my account** in **Settings → Data** keeps your scenes for 30 days; sign in within that time to restore them. **Hosted renders in Credits.** **Settings → Credits** says what a hosted render costs: fifty stills a day are free, then one credit a still, and path-traced renders, film frames and pictures over 1024 px cost a credit each. **Terms and privacy.** Both are at [puni.design/terms](https://puni.design/terms) and [puni.design/privacy](https://puni.design/privacy). **Tabs in the inspector.** Double-click an object in the rail and it opens as a tab that stays; a single click still previews. Tabs close from an **×**, reorder by dragging, and Scene keeps the first place. The panels' grips sit in the gaps between them. **The share page's name is a menu.** Who made the scene, when, the views, the description, the facts and the palette sit at the top; **Copy** offers the link, the embed code and the colours. On a phone the controls are one row, with Loop, Sound, Download and Full screen behind a **⋯**. **Credits for sculpting.** Your own keys spend no Puni credits; providers bill their calls. Puni's keys use three credits for a mesh and one more for a prompt picture, with three to start and packs in **Settings → Credits**. Checkout switches on per deployment; until then the page says so. **Connector setup.** The remote sign-in flow is in preview. Read [Connect Puni](https://puni.design/docs/agents/connect) for setup, compatibility errors, connection checks and token-based alternatives. **Doors into the guides.** **Guides** in the scene menu, a link at the end of the Keyboard dialog, and **Docs** on Settings → Agents. **Creator pages.** Turn on **Public page** in Settings → Profile and your live links appear at `puni.design/u/your-handle`. Choose a handle, and keep any link off the page with its own switch. **A richer About.** A share page's About carries the creator, when it was shared, how many views and copies it has, the palette, and the embed code. (It has since become the scene menu; see above.) **Downloads from a share page.** Save a picture, a GIF of the first twenty seconds, or a video, all made in your browser. **Agents with scopes.** A token made in Settings → Agents carries a scope: read, read and write, or read, write and share. The MCP door refuses a tool outside its scope. **A studio that says when it cannot draw.** A browser without WebGL sees the reason and the last saved cover instead of a spinner. **The login is the door.** Signing in shows six scenes you can orbit while you type. **Appearance.** Light, dark, system or custom colours, font size and pointer cursors, in **Settings → Appearance**. Motion follows your system's reduced-motion setting. **Help.** A **?** at the bottom left of the library opens the docs, the shortcuts and Settings. ## Earlier **Sharing.** Unlisted links to one saved version, remix permission per link, an embed with a host protocol. **The command line.** Pull, push, render stills and films, checkpoints, search, device sign-in. It is a preview for Puni's own team and is not published to npm; read [Setup](https://puni.design/docs/developers/setup). **MCP.** Tools for inspecting, editing, rendering and saving scenes from Claude Code, Codex and Cursor, and WebMCP for a browser that supports it. [MCP tools](https://puni.design/docs/developers/mcp-tools) lists every one. **A sign-in door.** ChatGPT, Claude.ai and Claude Desktop connect to Puni through its own OAuth door; the tokens are the same kind Settings makes and are revoked in the same place. It is switched on per deployment. **A render worker.** Agents on machines without a GPU can see: `puni_render_view` and `puni render view --remote` draw a scene the way the stage does, and a browser that cannot draw gets its cover made for it. Switched on per deployment. **Sculpt.** A picture or a prompt becomes a textured mesh on your own provider keys, from the command line, from an agent, and soon from the studio. **OpenAPI.** Every HTTP route is described at `/api/openapi.json`, kept honest by a test.

Where Puni has its own keys configured, a missing step can use [credits](https://puni.design/docs/account/credits) instead. The sculpt form shows the cost before submission. ## Add a key 1. Open **Settings → Providers** and choose **Add key** for the provider. 2. Paste the key and choose **Save key**. 3. Wait for **Verifying…** to finish. A saved key shows its last four characters. Keep the full key private. A stored and verified key confirms setup; a later model call can still fail because of provider billing, model access or a service error. ## Remove a key Choose **Remove** on its provider row. Later generation can use Puni's configured keys for credits, or ask you to add a key when that step is unavailable. Removing a key does not delete assets already generated. ## When setup fails A rejected key stays beside the form as an error. Check that the key belongs to the named provider and has the required access. For provider billing or model-access errors, check that provider account before submitting again. If Puni says key storage is unavailable, saving a key cannot complete on that deployment. Keep the error and try again after configuration is restored.

Splitting a Puni-paid sculpt into named parts is included in its mesh charge for three runs (the split and two re-rolls); after that, splitting it again needs your own fal key. ## Welcome and balance Open **Settings → Credits** to see your balance and recent activity. Opening the page grants three welcome credits once per account. A first paid sculpt can also grant them if you have not received them yet. Three credits cover one sculpt from a supplied picture. A prompt using both Puni providers costs four, so the welcome amount alone does not cover that run. ## Buy more When checkout is configured, choose a pack in **Settings → Credits** and follow checkout. The return page waits for payment confirmation before treating the purchase as complete. Recent activity records the credited purchase. If checkout is unavailable, the page says so and you cannot buy a pack. Your own provider keys remain a separate way to generate. Do not treat a checkout return page alone as confirmation that credits arrived; check the balance and activity. ## Hosted renders Renders on Puni’s machine also use credits: 50 stills a day are free, then 1 credit per still. Path-traced renders, film frames and pictures wider or taller than 1024 px cost 1 credit each. A render that is not delivered is returned. The meter applies only where the deployment turns it on. ## Failed sculpts and refunds When a paid sculpt is recorded as failed, its credits are returned once. Check recent activity for the refund; purchases refunded or disputed, and renders not delivered, also show there. If the job is still pending or the balance has not updated, keep the job and payment details when seeking help.

Your [creator page](https://puni.design/docs/surfaces/creator-page) is a separate public surface you choose to enable. [Open in Puni](https://puni.design/settings?section=profile) to open these settings. ## Name and picture Edit **First name** or **Last name**, then leave the field or press Enter to save. An error appears below the identity group if saving fails. Choose the picture (**Change picture**) to select a PNG, JPEG or WebP image, or **Remove picture**, which appears once you have one, to remove it. Wait for the change to finish before leaving. ## Email addresses 1. Enter the address under **Add an address** and choose **Add**. 2. Read the code sent to that address. 3. Enter the **Verification code** and choose **Confirm**. An unverified address also offers **Verify**. After verification, **Make primary** makes that address the main one for your account. You can remove a non-primary address with its remove action. Change the primary address before removing the old primary one. ## Connected accounts **Connected accounts** shows the sign-in providers linked to your account. A linked provider shows **Disconnect**. Google offers **Connect** only where Google sign-in is enabled for this deployment; finish the provider’s sign-in flow. A local workspace without an account shows that state instead of account controls. Signing out of a browser is handled in **Settings → Security**. Read [Security and privacy](https://puni.design/docs/account/security) for passwords and sessions, or [Devices](https://puni.design/docs/account/devices) for terminal access. --- Source: https://puni.design/docs/account/devices Raw Markdown: https://puni.design/docs/account/devices.md --- description: >- Sign a terminal into your library, check its access and expiry, and disconnect or reconnect a machine. figure: null icon: null order: 9 redirects: [] sourceRefs: - apps/app/src/features/settings/devices-section.tsx - packages/backend/convex/studio/deviceAuth.ts - docs/device-auth.md status: available surfaces: - all title: Devices verifiedAt: '2026-10-11' --- A signed-in terminal holds a token for your library. It does not need your password in a command or script. [Open in Puni](https://puni.design/settings?section=devices) to open these settings. ## Connect a machine 1. In **Settings → Devices → Connect a machine**, copy the command, or run it below. 2. Open the address the terminal prints, sign in, and type the code it shows. 3. Check what the request says it is, the access it asks for, and when and where it started before approving. 4. Return to the terminal and wait for sign-in to complete. ```bash puni auth login --base-url https://puni.design ``` Approve only the request you just started: a code someone sent you will show another time or place. A machine asks for read and write; run the command with `--scope share` if it should also publish share links. If its code expires, run the command again for a fresh one. The terminal token lasts thirty days and is stored at `~/.config/puni/credentials.json` with access limited to your user. ## Inspect connected devices **Settings → Devices → Connected** lists each machine, when it connected, its last activity and when its token expires. Agent-client tokens appear separately in **Settings → Agents**. ## Disconnect and reconnect Choose **Disconnect** on the machine's row to revoke its access. That terminal must run the sign-in command again before it can use the library. An expired token also needs a new sign-in. Local scene-file commands can work without a library connection. Remote project commands need a signed-in machine with the appropriate access. Read [Scopes and tokens](https://puni.design/docs/agents/scopes-and-tokens) for access levels, or [Auth commands](https://puni.design/docs/developers/cli-auth) for terminal details.
