* feat(storybook): prototype guided AI setup and task assignments
* refactor(storybook): adopt shared control foundations
* refactor(storybook): build AI setup on current settings foundations
Move the prototype to settings/ai-setup and compose SettingsSection, SettingsGroup, SettingsRow, AppAlert, AppBadge, and AppCheckbox instead of local section, status, and badge markup. Replace the nonexistent danger color and raw amber with the error and warning tokens.
* feat(ui): add a shared radio group
AppRadioGroup wraps the Reka radio group with typed options, labels each radio by its option text with any description as its accessible description, and supports all arrow keys unless an orientation is set. The AI setup wizard uses it for the spending choice, named by the step heading, and shares the choice card style with its checkboxes.
* fix(ui): draw unchecked checkboxes on the field background
AppCheckbox filled its box with the surface (text) color, so unchecked boxes were nearly black in the light theme and nearly white in the dark theme. Use the panel field background and accent hover border shared with the radio group and switch.
* refactor(storybook): drop the simplified AI connections panel
AI setup has two modes: skippable guided onboarding for most people and the existing advanced settings for power users, both editing the same model settings. Remove the third, simplified connections and tasks panel. The wizard's Advanced settings action and the returning-user screen now stand in for ModelsPanel, which offers Run guided setup. Removing Gateway's own Back button also fixes the blank screen it led to.
* feat(ai): plan guided AI setup from the model catalog
planOnboarding proposes design and vision models from the access a person already has, using the real provider and agent catalog, and falls back to OpenRouter only when pay-as-you-go is allowed. applyOnboardingPlan merges a confirmed plan into the model settings, reusing matching connections and profiles, keeping roles it was not asked about, and dropping only the empty fresh-install profile.
* refactor(ai): share model provider display names
Move the provider, agent, and Pi display-name lookup out of the model settings workflow so guided setup can reuse it.
* feat(ai): offer guided AI setup over the real model settings
Guided setup asks what AI should help with, what access the person
already has, and whether pay-as-you-go models are allowed, then
proposes design and vision models from the provider and agent catalog.
Connections reuse the provider key field and connection test, keys are
saved through the credential manager, and the confirmed plan is merged
into the model settings, keeping anything configured by hand. Saving
reports saved, partial, or failed like the profile editor.
A fresh install whose model settings are still the empty placeholder is
offered setup once with a skippable welcome; existing setups never see
it. Settings → AI & agents can run it again, and Advanced settings hands
off to the model editor. The Storybook fixtures for agents, OpenRouter
sign-in, Vercel AI Gateway, and the local server are replaced by the
real flow, with all copy translated.
Browser tests start with the offer dismissed through the shared
Playwright storage state; the first-run spec clears it.
* fix(ai): keep configured models and credentials safe in guided setup
Running guided setup again planned from the catalog defaults, so it
replaced hand-configured design and vision models and dropped their
settings; it now keeps a configured model while its access is still
selected or onboarding cannot offer that provider, and keeps vision when
nothing new covers it. Reused profiles must have the capabilities the
plan relies on, and an explicit vision assignment without image input is
cleared.
A server's saved key and its status now apply only to the connection at
the address being entered, and its connection test uses that
connection's API type. Entered keys are copied before saving, so closing
setup mid-save no longer drops them, and the Models list refreshes key
status after setup saves a key. Servers that do not check keys get a
hint to enter any value, and a step that only keeps configured models
says so instead of showing nothing.
* test(ai): check key status right after guided setup
The Models list must show a key saved by guided setup as connected without reopening Settings.
* feat(ai): sign in to OpenRouter from guided setup
OpenRouter can now be connected with its OAuth PKCE flow instead of a
pasted key. In the browser, sign-in opens in a popup that returns to a
static callback page on the app's origin, which relays the redirect to
the editor over a BroadcastChannel, so the editor never navigates away.
The desktop app opens the system browser and receives the redirect on
a one-shot 127.0.0.1 listener, the localhost callback OpenRouter
documents. Either way the editor checks the state, exchanges the code
for a key directly with OpenRouter, fills it in, and runs the
connection test. Waiting, blocked pop-ups, cancellation, expiry, and
failures are reported in the step, which keeps the pasted-key path.
Setup no longer offers Clear for a saved key, since removing keys
belongs to the advanced settings, and the service worker leaves
/oauth/ pages to the network.
* fix(settings): report unreadable model keys as unavailable
A saved key the browser credential store could not read, for example one left from an older session on the same origin, rejected the model status refresh and the startup credential check, which surfaced as a global error toast. Each read failure now marks only that connection as unavailable.
* feat(ai): map every role in guided setup and verify OpenRouter sign-in
Guided setup now proposes a model for design, vision, review, and fast
work, and the review step is a map of those roles with every suitable
model from the connected providers and a "Use recommended setup"
shortcut. Fast work defaults to the provider's catalog model tagged as
fast; behind an agent, review and fast work use the API model chosen
for vision. Review and fast work are never asked about, so a configured
choice, including none, stays unless it follows a design model it can
no longer follow.
The pay-as-you-go question only appears when the access already
selected leaves a requested role without a model, so choosing
OpenRouter or another account no longer asks it.
After signing in with OpenRouter, setup checks the key with
OpenRouter's key endpoint, which costs no credits, instead of a text
generation test. The step then says it is signed in, names the key,
warns when the account has no credits yet, and offers another account
in place of the key field and test button.
* feat(ai): offer OpenRouter only for goals nothing selected covers
The separate pay-as-you-go step asked an abstract question even when
the selected access already covered every goal. The connect step now
names a goal nothing selected can cover, such as visual review behind
a coding agent or a local server, and offers to add OpenRouter for it;
once added, it says OpenRouter fills the gap and can be removed again.
Setup can finish without visual review, but not without a design model.
A local or company server can be marked as able to read images, which
lets it cover visual review and makes it the preferred vision model
over a paid account.
* feat(ai): show provider logos and more providers in guided setup
Guided setup shows monochrome logos for coding agents, API accounts,
and local servers, from LobeHub's MIT-licensed static SVG set loaded as
an `ai` icon collection, so they follow the theme like Lucide icons.
DeepSeek, Z.ai, and MiniMax are offered under "More providers", and a
local server can start from the Ollama or LM Studio address instead of
typing it.
* feat(ai): guide coding agent setup in guided setup
Choosing Claude Code, Codex, or Gemini CLI in the desktop app now checks
whether the agent's ACP program and OpenPencil's MCP server, which
agents use to reach the canvas, are installed. An allowlisted
agent_lookup command finds the program on the same widened PATH as the
MCP lookup. The card shows install commands only for what is missing,
checks again on request, links a new setup guide, and copies a prompt
that asks an agent the person already uses to install both, confirm
they are on PATH, and sign in. In the browser, the agent section links
to the desktop app.
* fix(ai): space the More providers toggle like a group heading
The toggle sat flush against the account cards above and below it; it now reads as a group heading with the same rhythm as the other sections.
* feat(ai): detect and install coding agents in guided setup
Adopt the local agent discovery from #847. A desktop agent_lookup
command reports each agent's own CLI, its ACP adapter, npm, and
OpenPencil's MCP server on the widened PATH without starting any of
them, and the app can install a missing adapter or the MCP server with
npm, limited by the shell capability to those exact packages and the
MCP version that matches the app. Guided setup now tells "installed but
the OpenPencil adapter is missing" apart from "not installed", offers
one-click installs, links each vendor's own setup guide, and keeps the
manual commands and setup prompt for the browser, missing npm, or a
failed install. Codex install instructions move to
@agentclientprotocol/codex-acp, which replaces @zed-industries/codex-acp.
Kiro CLI support from the same pull request is left for a separate
change, since it needs ACP transport work.

* build(app): resolve LobeHub icons with import.meta.resolve
The architecture lint forbids createRequire in ESM build code.
* test(app): seed AI setup specs through storageState
Follows the storage seeding used by other browser specs and the import type rule.
* feat(ai): set up Pi with its own sign-ins in guided setup
Pi now runs with the providers signed in to in the Pi CLI and Pi's
default model. The Harness companion reuses ~/.pi/agent; the app reads
only Pi's settings.json for the default model and never auth.json. A
saved key is still used as an AI Gateway key.
Guided setup offers Pi next to the other coding agents. On the desktop
it checks the Harness companion, the MCP server, and Pi's default
model, and installs the companion with one click through npm.
Agent discovery now reads the installed versions of the MCP server and
the Harness companion from their package.json without starting them.
Setup flags a version that does not match the app and shows the update
command for the package manager that installed it, instead of
reporting the server as installed and failing at the first message.
* feat(ai): check agent companions before a chat starts
A Pi chat without the Harness companion, or any agent chat whose
companion or MCP server version does not match the app, failed when the
process started and showed only the generic request error. The chat now
checks the companions through agent discovery first and names the fix,
with an action that opens guided setup. Pi sign-in and model problems
use the same path.
The Pi model editor shows the same companion, MCP server, and default
model status as guided setup, and no longer requires a model ID, since
Pi falls back to the default model set in Pi.
Supersedes the companion detection in #566, which ran the companion to
read its version and required an exact version match.
* fix(harness): start Pi sessions with MCP tools and keep unsent messages
Pi chats in the desktop app always configure OpenPencil's MCP server,
and three companion problems stopped them:
- @ai-sdk/harness-pi imports pi-mcp-adapter, which publishes TypeScript
sources. Node refuses to strip types under node_modules, so the
companion now strips them through a module load hook limited to
TypeScript dependencies. Bun runs them as is.
- pi-mcp-adapter imports @earendil-works/pi-tui, declared only as an
optional peer, so npm left it out. The companion depends on it at the
version pi-coding-agent uses.
- Pi reports live-process resume, yet the service handed it state saved
by an earlier session, and the just-bash sandbox cannot resume, so
every later session with that ID failed. Live-process backends now
start fresh and drop saved state.
When a chat cannot start, the composer now keeps the typed message
instead of discarding it.
* fix(harness): keep companion stdout for protocol messages
Pi prepares the packages listed in a person's Pi settings with npm,
which inherits the companion's stdout, and libraries log through
console.log. Both landed in the JSONL protocol stream, where the app
discarded them with warnings. The companion now keeps the real stdout
for protocol messages, sends other stdout writes to stderr, and quiets
npm on success through its environment.
The type-stripping hook no longer prints Node's experimental warning,
and the app logs companion stderr as diagnostics rather than errors,
since failures arrive as protocol errors.
Document Pi in the coding agents guide, the AI chat page, and the
README: guided setup installs the companion, Pi uses the Pi CLI's
sign-ins and default model, an AI Gateway key is optional, and the
companion needs Node.js 22.15 or later.
* test(harness): keep the pi-tui pin in step with pi-coding-agent
The companion depends on pi-tui only because pi-mcp-adapter imports it while declaring it optional (nicobailon/pi-mcp-adapter#805). Upgrading @ai-sdk/harness-pi moves pi-coding-agent, and a pin left behind would make npm install a second, mismatched pi-tui. The test fails until the pin matches.
* test(ai): follow the model catalog in guided setup tests
The plan and apply tests repeated catalog default and fast model IDs, so master's model update broke them without any change in setup behavior. They now read those models from the catalog.
* test(ai): keep the model catalog helper with the shared test helpers
Unit test homes under tests/app accept only *.test.ts files, so the onboarding tests' catalog helper moves to tests/helpers/ai.
* docs: tighten the guided setup and Pi changelog entries
Name every provider and server preset guided setup offers, describe the role step as it now works, and shorten the Pi entry.
* test(ai): type the guided setup test stubs for the test typecheck
Master now typechecks the test suites: fetch fakes go through fetchStub, the chat ref is shallow like the real one, and mocks declare the arguments the tests inspect.
* test: type the tabs module in the closed-documents spec
The spec imported the tabs module by its served URL without a type, which fails the test type check on master.
* test(ai): assert outcomes instead of copy in guided setup tests
Drop the setup-prompt test, which checked prompt prose, the onboarding wrapper cases that restated discovery, and the coversGoals case. Story plays and the OpenRouter E2E flow now assert controls and saved models instead of sentences and catalog model names, and the fast-model helper checks the planned model's catalog entry instead of recomputing the choice. tests/AGENTS.md states the rule.
* feat(ai): return desktop OpenRouter sign-in through a deep link
The desktop app ran a hand-written HTTP server on a localhost port to receive OpenRouter's redirect, and OpenRouter labels apps with a localhost callback by host and port. OpenRouter now redirects to a page on the web app that opens openpencil://oauth/openrouter with the same query, and the desktop shell forwards that link to the webview as an oauth-callback event. The attempt that started sign-in checks the state and exchanges the code with its PKCE verifier, which never leaves the app.
* feat(ai): ask OpenPencil's companions for their version
The desktop app read a companion's version by following its executable's symlink up to a package.json. That only worked for the Unix npm and bun layouts: Windows .cmd and .exe shims and version-manager shims such as Volta and mise are not links into the package, so the version was always unknown and an outdated companion went unreported. The MCP server, stdio bridge, and Harness companion now print their version for --version, and the app runs each installed one with --version --help under a timeout. A release older than --version prints its help or exits without a version line, which reads as outdated. A bun global install on Windows now gets the bun update command too.
* fix(ai): ask for a Pi sign-in when Pi has none
readPiAccount returned an account whenever a home folder existed, so a chat with no Pi sign-in reached the Harness and failed with a provider error instead of the guided pi-sign-in fix. It now reports whether Pi's auth.json exists, without reading it, and the capability allows that one check.
* fix(ai): keep the attachments of a message that was not sent
A message that never reached the chat came back to the composer as text only: its image previews were revoked and its referenced layers dropped. The composer now takes back the whole submission, or releases the previews when newer text replaced it. A message counts as sent once the chat holds it, so a failure after that no longer hands it back to be sent twice.
* refactor(app): read the app version from one constant
Four modules each derived the app version from the build define with the same test fallback.
* refactor(ai): report chat submission errors from their own module
Reverting turns from master and keeping unsent drafts together took useChatSubmission past the composition-root limit. The test for reverted turns now passes the setup messages the submission reports.
* refactor(app): keep the app version with the runtime config
Tools typecheck src/constants.ts through app imports without the Vite defines, so the version constant moves to src/app/runtime/version.ts.
* test(desktop): check npm installs of the companions at the app's release version
The scope test named the companion packages and version literally, so it would keep passing if the app requested something else. It now builds them from the app's package names and the release version a build embeds.
* refactor(ai): parse OpenRouter, Pi, and sign-in callback data with Valibot
The OpenRouter key info and code exchange checked their JSON with typeof chains, Pi's settings parsed JSON in a try before validating it, and the desktop sign-in trusted the shell's callback payload as typed. Each now goes through one schema.
* fix(ai): take back a message whose images could not be prepared
A message with images appears in the chat before its images are prepared, so a preparation failure counted as sent: the draft did not come back and its previews were already revoked. A message now counts as sent once it is dispatched; a failure before that removes the shown message and hands the draft back, and the composer's previews are revoked only after dispatch.
* fix(ai): restore an unsent message only in its own conversation
Switching conversations while a message was being sent could restore it into the newly opened one. The draft now comes back only if the conversation is unchanged, and its previews are released otherwise.
* refactor(app): keep one app version constant
The update window added an APP_VERSION to src/constants.ts beside the one in src/app/runtime/version.ts. The tools typecheck reaches src/constants.ts without the Vite defines, so the update window now reads the runtime one.

* fix(core): start new layers with Figma's defaults in the editor and plugin API
The plugin API created bare nodes: frames, components, and shapes without fills, and lines and vectors without strokes, so scripts written for Figma drew nothing. Drawn lines also had a black fill instead of a stroke and were invisible. Both paths now share newLayerDefaults, recorded from Figma desktop 126: frames and components white with frames clipping their content, shapes #D9D9D9, lines and vectors a black 1 px stroke, text black. A stroke a script adds gets the 1 px default weight, and an empty vector has no render bounds.
* fix(core): combine variants as Figma does from the canvas and from scripts
The plugin API and the editor command each built component sets their own way, both with 40 px of padding and a grey fill. Figma's command pads the variants by 20 and outlines the set with a 1 px dashed #8A38F5 stroke; its plugin API wraps them exactly with no fill or stroke. One variantSetProps now places and styles the set for both, with a canvas or script style, and applyVariantProperties derives variant properties for both.
* fix(core): report group children in their container's space in the plugin API
Figma's plugin API places children of groups and booleans relative to the nearest real container and refits a group whenever a script changes one of its children. Ours reported group-relative positions and never refit, so scripts placing layers inside groups landed them in the wrong place. x, y, and relativeTransform now map through the groups around a node, and geometry changes, appendChild, insertChild, and remove refit the surrounding groups. The refit moves to Scene Graph as fitEnclosingGroups, shared by the canvas (with undo) and the plugin API.
* test(core): pass script-style strokes and typed components in parity tests
* test(e2e): expect Figma's default shape grey in the scene freshness spec
* fix(vue): draw lines by length and angle as Figma does
The Line tool sized a line as the box spanned by the drag. With the stroke a new line now gets, that box drew as a rectangle outline. A line now starts at the press point with the drag length as its width, no height, and the drag angle as its rotation, as Figma's Line tool makes it; Shift snaps the angle to 45° steps, as the docs already described, and a click makes a 100 px horizontal line.
* fix(core): give each new layer its own copy of the default paints
The defaults spread each paint shallowly, so every layer shared the colour object of the module-level default and editing one layer's colour in place changed the next new layer. Copy the paints with the Scene Graph copy helpers.
* fix(core): group, ungroup, and combine layers through shared code in the plugin API
The plugin API wrapped layers, ungrouped, made booleans, and made components from layers with its own code. Ungroup moved the children to the top of the stack, booleans were named "Boolean union", and a component made from a frame cloned its children under new ids. These now run through the editor's shared wrap, ungroup, and boolean functions, with the placement and defaults recorded in Figma desktop 126: a group or boolean without an index goes on top, ungrouped children take the group's place, booleans are named after the operation and filled with the default grey, a frame becomes a component in its place with its children, and any other layer is wrapped in a white component named after it. Undoing a wrap in the editor now returns each layer to its own place in the stack.
* fix(core): group, frame, combine, and make components from the canvas as Figma does
Recorded in Figma desktop 126: a container made from the canvas takes the topmost selected layer's place, Frame selection adds no fill and does not clip, a component wrapped around layers is white and takes a single layer's name, and a boolean is filled like its topmost operand, or its base for Subtract, without strokes. The canvas commands and the plugin API now share the wrap parent check, stack ordering, component rules, and boolean paints, and the plugin API's createComponentFromNode converts groups in place as Figma does. Undoing a boolean returns each operand to its own place in the stack.
* refactor(core): reuse translate when centering pasted layers
* fix: match Figma's transforms, strokes, booleans, sections, and names
Each behaviour was recorded in Figma desktop 126 with the same script, or
from its canvas, and both the editor and the plugin API now share it.
- Scripts turn a layer counterclockwise about its top-left corner, read x
and y as that corner, keep it in place on resize, can set
relativeTransform, and get absoluteBoundingBox around the turned layer.
appendChild and insertChild keep x, y, and rotation in the new parent
instead of the canvas position, which the create and reparent tools
inherit.
- A layer keeps its stroke weight and alignment without strokes, in the
model and through .fig export and import. strokeWeight and strokeAlign
apply to every stroke, and a stroke added from the panel or a script
takes the layer's.
- Booleans size to their result when a renderer can measure it, from the
canvas, from scripts, and when an operand moves.
- New sections take Figma's fill for the interface theme, a faint white
stroke, and 2 px corners; sections and component sets draw with their
own radius.
- Layers drawn on the canvas and the containers it wraps layers in are
numbered past the highest number on the page; scripts keep plain names.
* test(core): dispose the editor in the canvas boolean bounds test
Attaching CanvasKit installs a global text measurer, and the test left it installed, so later text measurement tests in the same process found it.
* fix(core): undo a boolean's group refit and clamp dashed set corners
Sizing a boolean to its result also refits the groups around it, and undo left them refitted, so the operands came back displaced. createBooleanOperation returns the fit, and undo reverses it first. A component set's dashed outline now clamps its radius to its bounds as the fill does, and a script's resize refits the enclosing groups once, after the corner is restored.
* refactor(app): share Markdown rendering outside chat
Move the vue-stream-markdown wrapper, inline code, token mapping, and
styles out of chat into components/markdown and theme/markdown, so other
surfaces can render Markdown without importing chat components. A density
attribute selects the compact chat styles or a comfortable reading size,
and Shiki highlighting is opt-in. ChatMarkdown keeps its streaming render
key and wraps the shared component.
* refactor(ui): extract AppProgress from the toast
The toast drew its own progress track, fill, and label. Move them into
AppProgress in ui/feedback, built on Reka's Progress so the bar reports
its value and indeterminate state, with an accent tone for panels and a
current-colour tone for coloured surfaces. ToastProgress becomes the
shared ProgressAmount. AppPlaceholder also accepts an h1 label for
placeholders that stand for a whole window.
* feat(desktop): show updates in a Software Update window
The update prompt passed the release's CHANGELOG section to the native
confirm dialog, which cannot format Markdown or scroll, so the 0.15.1
notes showed raw headings and pushed the buttons off screen.
When the main window finds an update it now opens a small `updater`
webview loading its own `updater.html` entry, which never boots the
editor. The window renders the notes with the shared Markdown component
in a scrolling box and links to the full release page.
Installing is split into stages. The download shows progress and can be
cancelled; Tauri cannot abort it, so Cancel detaches and a later Install
reuses the running download. On macOS and Linux the update then installs
and the window offers Restart Now or Later. A restart, and on Windows the
installer that quits the app, first asks the editor window to run the
same unsaved-documents approval as Quit. Failed checks, downloads,
installs, and restarts keep the release visible and can be retried. The
window's capability grants only update, restart, close, and link
opening.
Closes#743
* fix(desktop): stop waiting for a restart reply from a closed editor
The Software Update window waited for the editor's answer with no bound,
so an editor closed mid-request left Restart Now, and the Windows
install, stuck. Treat the editor window's destruction as approval: it
ran its own unsaved-changes prompt and holds no documents. A timeout
would instead fail people still answering that prompt.
* fix(desktop): refuse writes where a written file would run
The fs scope let the webview write, create folders, and delete anywhere. Documents may still be saved anywhere, but the global scope now denies login items and startup folders, PowerShell profiles, and the global package and executable folders where coding agents and OpenPencil's companions live, and writes to the MCP discovery files agents trust. requireLiteralLeadingDot keeps hidden files and folders, such as shell profiles and agent settings, out of ** on Windows as Tauri already does on macOS and Linux. A native test saves a document and is refused a LaunchAgents file, a home dotfile, and the discovery file.
* fix(ui): draw segmented controls at panel field height
Panel fields moved to 24px when sizing tokens became plain utilities, but segmented control items stayed 22px inside a 2px padding, so the Typography and resizing controls stood 2px taller than the fields beside them. The panel foundation story renders its inputs at the panel size and checks 24px.
* test(storybook): run every story and its play function
No test ran the play functions, and five had gone stale: the layer tree example labelled a wrapper with the same name as its row, the chat composer's label gained an ellipsis, the MCP failure story queried a test id attribute the app does not use, and the property primitives story still collapsed sections whose titles are static now. bun run test:storybook now renders every story and fails on a story or play function that throws.
* fix(desktop): deny protected folders themselves and writable opens of the discovery files
Each protected folder is denied alongside its contents, so a recursive remove cannot target the folder itself, and the MCP discovery files are denied to open as well as write, since opening with truncate would empty them. The native test opens the discovery file for writing without truncating, and removes only files it created. The story test waits for storyFinished, which follows afterEach, and judges exceptions and non-accessibility reports.
* test(desktop): run the file scope check only on macOS
Its protected paths are macOS ones, so other platforms skip it rather than pass for another reason.
* docs: note that documents opened from hidden folders can still be saved
The behaviour tests used property IDs that may be null as references and read a parsed .fig buffer and the node iterable as arrays, so bun run check failed on master. CI does not run the test typecheck.
WebKit's IndexedDB cannot store Blobs in private contexts and aborts the write with 'Error preparing Blob/File data to be stored in object store'. Attachment previews and tool change images are Blobs, so after the first image or document-changing reply every save of the conversation failed. Messages are now stored with each Blob as its type and bytes, converted before the transaction opens and back on read; Blobs saved earlier still read as they are. A WebKit test, which runs in a private context, fails without this and passes with it.
* feat: author behaviours on main components
A main component or component set can behave as a Switch, Checkbox,
Slider, or Tabs, after Reka UI's primitives. The behaviour lives in
OpenPencil plugin data: boolean values bind to variant or boolean
properties with the values meaning on and off, a number keeps its own
range since Figma has no number property, and the control's
subcomponents bind to the component's slots. A Behaviour section in the
properties panel adds, binds, and removes it, each as one undo step,
and flags required bindings that are missing. The canvas-only layout's
pill becomes a component that preview will reuse.
* feat: preview instances with behaviours on the canvas
View > Preview (Cmd+Alt+Enter) puts the canvas in preview: a lone canvas
switches to the canvas-only layout with a Previewing pill, and a split
canvas previews on its own side. Clicking a Switch or Checkbox flips it,
dragging a Slider moves its thumb and range, and clicking a Tabs trigger
shows its panel. Preview keeps its state on copies of the instances it
touched, in a private graph with the document's ids, and the canvas
draws those copies in place of the originals, so the document, undo,
autosave, and collaborators never see it. Escape or the pill leaves
preview, Reset restores every control, and editing shortcuts, labels,
and outlines stay off while previewing.
* feat: translate behaviour and preview strings; cover preview with an e2e flow
* refactor(vue): reuse VariantDefinitionControl for behaviour property options
* refactor: split variant actions and preview interactions by domain
Variant authoring was one 706-line closure; it is now graph queries
(model), undo snapshots (history), property definition edits
(definitions), and the editor facade (index). Preview interactions move
into play/kinds, one module per control, registered by behaviour kind so
a new kind cannot ship without its contract and interaction. Behaviour
contracts are keyed by kind. In the Vue SDK, slot and variant authoring
controls get their own folders beside component-props and behaviour,
and the app's variant section joins slot/ and behaviour/.
* refactor: keep the behaviour model in scene-graph's plugin-data registry
Master now defines every OpenPencil plugin-data key in one typed registry
in scene-graph. The behaviour schema registers there as a field, and the
model and contracts move beside slots, exported from the package root;
the @open-pencil/core/behaviours subpath is gone.
* feat: interaction states and keyboard focus in preview
A behaviour can bind a variant property to the default, hover, pressed,
focus, and disabled states; binding it maps values named like those
states. Preview switches the instance's copy to the matching variant as
the pointer hovers, presses, and releases, keeps other values when the
set draws the combination and falls back to rest otherwise, and skips
disabled instances. Tab moves visible keyboard focus between controls,
Space, Enter, arrows, Home, and End use the focused one, and Escape
takes visible focus off before leaving preview. A Button kind covers
controls that only have states.
* feat: toggle, radio, group, progress, collapsible, and accordion behaviours
Radio group, toggle group, and accordion hold their items in a slot;
each item is an instance with its own behaviour, so a press inside the
slot goes to the group, which turns the pressed item on and the others
off through the item's own interaction. Progress shares the slider's
number handling through rangeControl, and a collapsible shows and hides
its content slot from its trigger, remembering its open state even
when no property draws it. Tabs and groups share arrow-key navigation.
* feat: text field, textarea, and number field behaviours
A behaviour value can now be text, bound to a text property, so
preview types into a copy of the field through the same property path
the editor uses. A bound Filled value switches to the placeholder
variant when the field empties. A number field keeps its own range,
shows its value through a text property, and steps from its increment
and decrement slots and the arrow keys. Text fields show focus from a
click, and the focused control receives every key; Option still types,
and only Cmd or Ctrl combinations stay shortcuts.
* fix: keep behaviour bindings when saving as .fig
Saving as .fig gives component properties new GUIDs, but behaviours
kept the old ids in their plugin data, so every binding read as missing
after reopening. The export now renames the ids behaviours bind with
the same GUIDs, on its own copy of the document.
* fix: let previewed controls resize layout imported from .fig
Layers from a .fig keep the sizes Figma computed, and auto layout
prefers them, so an opened collapsible or accordion item kept its
closed height in preview. When preview shows, hides, or retypes a
layer in a copy, it drops those sizes from the layer's copied ancestors
so auto layout sizes them again; untouched layers keep Figma's sizes.
* fix: publish behaviours and other plugin content with library assets
Every OpenPencil plugin-data field now declares its role: content that
exists only as plugin data (behaviours, OkHCL picks), format copies of
node fields written for files, or bookkeeping about where a document
or node came from. Library snapshots keep a node's content plugin data,
including other plugins' entries, and drop the rest; the asset hash
counts the same entries, so a behaviour-only change is offered as an
update while a .fig round trip still changes nothing.
* feat: name behaviour rows by meaning and create what they need
The Behaviour section named every main value "Value" under a "Values"
heading, and a component without matching properties left an empty
picker with no way forward. Rows are now named for the control (On,
Checked, Pressed, Text), rows the control needs or already uses come
first, and the optional rest folds under More options; a button keeps
its states in view. An empty row creates what it needs in one undo
step: a text layer and text property, Off and On variants on a set, or
a slot frame for a part. The missing chip names the row it means and
takes you there.
* fix(dom-css): position free layers, hug content, and round ellipses
HTML and Tailwind export stacked the layers of frames without auto
layout in block flow, wrote fixed pixel sizes for auto layout frames
set to Hug and for auto-sizing text, and drew ellipses as boxes. Layers
a parent does not lay out are now absolutely positioned at their
coordinates inside a relative frame, hugging axes are left to the
content, and ellipses get a 50% radius.
* feat: run preview as live Reka UI islands over the canvas
Preview simulated controls on the canvas: copies of instances, a
handler per kind, its own key routing, and append-only text. It now
runs them as real components. Each top-level layer that holds an
instance with a behaviour becomes an island: its layers are projected
to DOM through dom-css into a shadow root laid over the pane at its pan
and zoom, and each behaviour mounts its Reka UI primitives on its
layers, so text fields are real inputs and focus, keys, and layout are
the browser's. Core's resolvePlayState shows instances in a state on a
private graph, so the component's variants draw it, and controls are
keyed by layer path so a variant switch keeps their DOM. The canvas
leaves island layers to the islands, and the canvas play runtime and
its key routing are gone.
* fix: derive variant properties from Property=Value component names
figma.combineAsVariants and Combine as variants only derived variant
properties from slash-separated names, so components named as Figma
names variants, such as State=On, Size=Large, became a set with no
properties. Both now derive each named property and its values, after
the slash form.
* feat: script and tool access to behaviours by name
Behaviour contracts follow Reka UI's anatomy: tabs keep their triggers
in the list slot and their content panels in a panels slot, and a slot
of repeated parts names the Reka part of its children. A behaviour
spec names component properties and slots instead of ids and resolves
to the stored behaviour and back, with errors that list what the
component has.
Scripts get an `openpencil` global next to `figma`, in the Figma API's
style: setBehaviour, getBehaviour with bindValue, bindPart, states,
and missing, behaviourKinds, and createSlot. The eval tool, the CLI,
and app automation compile scripts through one compileScript, so the
CLI now returns the last expression as the others do. MCP and AI chat
get set_behaviour, get_behaviour, and create_slot.
* feat: write controls in design JSX with Reka UI's element names
`<Switch.Root modelValue="State">` renders a main component, or a set
when its children are variants, that behaves as a switch, and
`<Switch.Thumb>` the slot that draws its thumb, one slot across the
set's variants. Inputs become the text property of a field, tab
triggers and panels go in their List and Panels slots, and a group's
items are `<RadioGroup.Item of={…} />` instances in its Items slot.
JSX export writes components with behaviours the same way, so they
render back unchanged. The authoring reference documents controls, and
the codegen and chat prompts now include it verbatim instead of
dedenting its code examples.
* chore: format the CLI export test
* docs: document slots, behaviours, preview, and the openpencil API
The components guide covers slots, behaviours, and preview with its
shortcut; scripting covers the openpencil global and eval's last-
expression result; the MCP and AI chat pages list the new tools; the
features overview, README, and roadmap mention working controls. The
chat prompt says how to build a control, and the codegen prompt builds
components with behaviours on their Reka UI primitives.
* chore: format the eval CLI test
* docs: explain behaviours and preview islands, and guide the openpencil API
A development page explains the behaviour model, the four authoring
surfaces, how preview islands turn a control's state into live Reka UI
components, and how to add a kind; the architecture page links it. The
Core guide sets the rules for OpenPencilAPI: Figma-only `figma`,
OpenPencil features on `openpencil` in the same style, one
compileScript, names over ids, and docs with every member. Package
READMEs mention the openpencil global, PlayIslands, Reka-named JSX, and
the behaviour model. Design JSX's behaviour modules move into a
behaviours folder instead of a suffixed sibling.
* refactor: center pasted layers through translate
centerNodesAt repeated translate's loop, which test:dupes reports on
master too.
* fix: validate behaviour ranges and guess on and off by name
A number value now needs max above min and a positive step: the schema,
specs, and the panel reject a range a slider cannot step through. Binding
a variant property guesses on and off by value name, as specs do, and a
boolean property gets no on/off pair. Part bindings are read through
partBinding, a replaced document restarts preview from its designed
state, and the e2e preview shortcut uses ControlOrMeta.
* feat: make the Behaviour section say what to do next
A slider's range fields now carry inline Min, Max, Step, and Start labels.
States offers Add state variants, which adds a Default, Hover, Pressed,
Focus, and Disabled variant and binds them; Add Off and On variants and
Add state variants turn a lone main component into a component set first,
and a part's slot can be added to a set, in every variant under one slot
id. Rows that could do nothing are gone: no empty pickers and no hints to
combine variants by hand, and an unbound Disabled is left to the states.
A warning line names what is still needed and replaces the missing chip,
and the Switch's main value is called Checked.
* fix: keep each slot to one part and keep creating slots at hand
A slot draws one part, so the Behaviour section no longer offers a slot
another part uses, and specs (the openpencil API, tools, and JSX) reject
binding one slot to two parts. A part's picker keeps an action to add a
new slot in its footer, so adding the first slot no longer hides it for
the other parts.
* feat: let a collection name the attribute its modes switch by
Manually switched modes were always selected by data-<collection name>, so a collection called New wrote data-new and a codebase already using data-color-scheme could not be matched. A collection can now name its attribute in the inspector, validated so a stylesheet can select it as is. The stylesheet and exported code use it, setting it is undoable, and .fig files keep it in the collection's plugin data.
* fix: show the switch attribute only where there are modes to switch
* fix: return to the list after committing the switch attribute
* fix: keep a collection's switch attribute when a new one is refused
setModeAttribute cleared the attribute when given a name a stylesheet cannot select on; it now leaves the current one, and only an empty name restores the default. In the inspector, Enter on a refused name keeps the focus so it can be corrected.
* docs: describe the switch attribute in the mode conditions
The Switched manually row still said the attribute is named after the collection. The changelog had collected four copies of the variables dialog entry through rebases; one remains, with the switch attribute in it.
The variables dialog now uses the tokens panel, so useVariablesEditor, useVariablesTable, useVariablesDialogState, and the table-only formatModeValue, parseVariableValue, and shortName helpers have no users. Removing them drops the @tanstack/vue-table dependency; their SDK pages redirect to useVariables.
* feat: prototype the design tokens panel
Undoable editor actions for token fields and mode conditions, a token view model, and table, inspector, collection and stylesheet panels shown in a Storybook story with a real editor.
* feat: lay the tokens panel out for mobile
Below the mobile breakpoint the collection tabs become a select, the list shows one chosen mode with the CSS name under each token, and the token, the modes, and the stylesheet each open over the list behind Back. CodeViewer can fill its container for the full-screen stylesheet.
* feat: share drill-in navigation and put tokens on a listbox
PanelDrillIn gives detail views one back control that names where it returns, a slide preset from theme/motion, and focus that moves into the detail and back to what opened it. The Settings model editor and the tokens panel's mobile views use it. The token list is a Reka Listbox with arrow-key navigation and labelled groups, and the inspector and stylesheet swap with a short fade under the motion policy.
* feat: lay the tokens panel out by container width
The panel switches to the compact drill-in by its own measured width, and the list's columns follow the list's width through container queries, so the panel adapts inside dialogs and split views, not only on phones. src/AGENTS.md now says when to use container queries, measured size, and viewport breakpoints.
* test(core): group the variable undo tests in a domain folder
* feat: edit variables as tokens in the variables dialog
The variables dialog now hosts the tokens panel: a grouped token list with CSS names, an inspector for each token and for the collection and its modes, and the live stylesheet. It keeps adding variables by type, search, collection and mode management, and copying the document's stylesheet, and lays out by its own width down to phones.
useVariables().collections returns copies, so components given a collection see modes added or renamed in place, and addVariable returns the new ID so the panel can open it.
* fix: satisfy the type-aware lint in token updates and panel stories
* docs: describe the tokens panel in the translated variables guides
* feat: say when each mode applies in plain words
A mode's condition was a raw CSS field that designers could not read. Each non-default mode now picks when it applies (switched manually, system dark or light mode, high contrast, reduced motion, screen or container width, or custom CSS), with the CSS it writes shown underneath and a note on how the mode behaves on the canvas and in exported code. Presets only write the condition string modes already store, so files round-trip unchanged. Column headers name the condition in words, and deleting the collection moves into a menu beside its name.
* feat: bring the variables dialog up to Figma's
The dialog now covers what Figma's variables dialog offers: collections and groups in a sidebar with counts, a group, search and type filter, type icons, names and values edited in place, drag to reorder, multi-select with a context menu, the Delete key and a side panel to duplicate, group and delete, aliases chosen from a variable picker and detached back to the value they showed, hiding from publishing, and an expand toggle. It opens from View → Variables… and the command palette as well as the Design panel.
It also fixes review findings: a single-mode collection labels its value Value, column titles share one font, a CSS name is typed after a fixed -- and checked by the CSS parser before it is saved, and the stylesheet previews CSS with the format chosen when copying. AppInput applies an instance's input classes last so they can override adornment padding.
* feat: undo and redo inside the variables dialog
Canvas shortcuts stop while any dialog is open, so Cmd+Z did nothing in the variables dialog although every edit there is on the editor's history. Undo and redo now take a document scope: they also run when the topmost layer is a dialog that edits the document, which the variables dialog marks, while menus, pickers and Settings still hold them back and a field with uncommitted text keeps its own undo.
Enter commits a field and returns focus to the list. The panel drops selections, group filters and collections that undo removed. A color picker session undoes as one step through a coalesce key on updateVariableValue, and undoing a deletion puts the variable back in its place.
* feat: search variables like the command palette
The variables search matched a substring of the name only, so a CSS name, a hex color or a description found nothing, and the palette, AppPicker and AppCombobox each spelled out the same Fuse.js options. One helper in @open-pencil/vue now owns the matching: fuzzySearch ranks results for lists people pick from, and fuzzyFilter keeps a list's own order for lists people arrange. The panel searches names, CSS names, descriptions and every mode's value, alias names included; useVariables() searches names and descriptions.
* fix: say a token group once when its name repeats it
Kits that mirror Tailwind classes name tokens like Gap/gap-1, which derived --gap-gap-1. A group the next segment repeats is now said once, giving --gap-1.
* fix: keep the add variable menu under its button after a resize
The toolbar swaps the icon button for the labelled one when the dialog widens. Reka keeps the anchor it mounted with, so the menu opened at the window corner; keying the trigger remounts it with the new button.
* fix: leave bound layers alone when variables are added or reordered
Adding, copying, or reordering variables re-resolved every bound layer in the document. In the shadcn kit two Avatar instances are saved at 24 while their binding gives 40, so adding a number resized them and relaid out about 7,800 layers, freezing the browser for seconds. These changes alter no bound value and now only request a render, as renaming already did.
* refactor: let the variables dialog own its undo shortcuts
Undo and redo in the dialog went through a document scope in the global shortcut registry, which decided whether the dialog was on top by querying Reka's dismissable layers in DOM order. The dialog now listens on its own content with a tinykeys handler built from the command keybindings: menus and pickers it opens portal elsewhere, so their keys never reach it, and the registry is back to one scope.
* refactor: read mode conditions with css-tree
Presets were recognized by normalizing the condition with regular expressions and matching another. css-tree, which Core already ships through unifont, now parses the condition into its media or container feature, so spacing, case and comments are handled as CSS does, and a non-breaking space, which CSS does not treat as whitespace, no longer turns a custom condition into a preset.
* refactor: take the mode attribute hint from modeAttribute
The hint for a manually switched mode cut the brackets off its selector with a regular expression. It now reads the attribute name and value from modeAttribute, which the selector is built from.
* fix: keep a refused CSS name in focus and color picker sessions apart
Enter on a CSS name the parser refuses no longer hands the keyboard back to the list, so the name can be corrected. The typed name is read with parseCSSName instead of stripping a leading -- by hand, so a pasted var(--name) works too.
Each color picker session takes a random undo key; a counter restarted when the inspector remounted, so two sessions on the same token could merge into one undo step.
* fix: keep token expressions and cleared fields in step with their variable
Editing a number left its CSS expression recording the old number, so reopening the file dropped the expression as edited elsewhere. A number now updates its expression, and an alias drops it, in the same undo step.
Undoing a token field that had been unset kept the key with an undefined value; it is now removed.
* fix: preview and detach aliases in their own mode
An alias in the Dark column showed, and detached to, what its target gives in the mode the canvas is in. Both now resolve in the column's mode.
* fix: drop tokens a filter hides from the selection
A search, group, or type filter could hide selected tokens that stayed selected, so the inspector, the bulk actions, and the Delete key still acted on rows the list no longer showed.
* fix: keep a drill-in's list out of the tab order while its detail slides
The list stayed focusable until the detail finished sliding in, and became focusable again under a detail sliding out. It is now inert from the moment the detail opens and the departing detail is inert. A detail with no field focuses its back control, and hidden inputs are skipped.
* docs: drop a duplicated Stroke entry from the changelog
Two merges left the Stroke-extends-Fill breaking change twice; the copy that still said strokes render solid only is outdated, since gradient and image strokes now import and render.
CanvasKit lays out no line for an empty paragraph, so the text editor found no caret until the first character was typed. A one-space line now gives an empty text's caret its height, and its alignment places it.
* fix(core): start new layers with Figma's defaults in the editor and plugin API
The plugin API created bare nodes: frames, components, and shapes without fills, and lines and vectors without strokes, so scripts written for Figma drew nothing. Drawn lines also had a black fill instead of a stroke and were invisible. Both paths now share newLayerDefaults, recorded from Figma desktop 126: frames and components white with frames clipping their content, shapes #D9D9D9, lines and vectors a black 1 px stroke, text black. A stroke a script adds gets the 1 px default weight, and an empty vector has no render bounds.
* fix(core): combine variants as Figma does from the canvas and from scripts
The plugin API and the editor command each built component sets their own way, both with 40 px of padding and a grey fill. Figma's command pads the variants by 20 and outlines the set with a 1 px dashed #8A38F5 stroke; its plugin API wraps them exactly with no fill or stroke. One variantSetProps now places and styles the set for both, with a canvas or script style, and applyVariantProperties derives variant properties for both.
* fix(core): report group children in their container's space in the plugin API
Figma's plugin API places children of groups and booleans relative to the nearest real container and refits a group whenever a script changes one of its children. Ours reported group-relative positions and never refit, so scripts placing layers inside groups landed them in the wrong place. x, y, and relativeTransform now map through the groups around a node, and geometry changes, appendChild, insertChild, and remove refit the surrounding groups. The refit moves to Scene Graph as fitEnclosingGroups, shared by the canvas (with undo) and the plugin API.
* test(core): pass script-style strokes and typed components in parity tests
* test(e2e): expect Figma's default shape grey in the scene freshness spec
* fix(vue): draw lines by length and angle as Figma does
The Line tool sized a line as the box spanned by the drag. With the stroke a new line now gets, that box drew as a rectangle outline. A line now starts at the press point with the drag length as its width, no height, and the drag angle as its rotation, as Figma's Line tool makes it; Shift snaps the angle to 45° steps, as the docs already described, and a click makes a 100 px horizontal line.
* fix(core): give each new layer its own copy of the default paints
The defaults spread each paint shallowly, so every layer shared the colour object of the module-level default and editing one layer's colour in place changed the next new layer. Copy the paints with the Scene Graph copy helpers.
* fix(core): group, ungroup, and combine layers through shared code in the plugin API
The plugin API wrapped layers, ungrouped, made booleans, and made components from layers with its own code. Ungroup moved the children to the top of the stack, booleans were named "Boolean union", and a component made from a frame cloned its children under new ids. These now run through the editor's shared wrap, ungroup, and boolean functions, with the placement and defaults recorded in Figma desktop 126: a group or boolean without an index goes on top, ungrouped children take the group's place, booleans are named after the operation and filled with the default grey, a frame becomes a component in its place with its children, and any other layer is wrapped in a white component named after it. Undoing a wrap in the editor now returns each layer to its own place in the stack.
* fix(core): group, frame, combine, and make components from the canvas as Figma does
Recorded in Figma desktop 126: a container made from the canvas takes the topmost selected layer's place, Frame selection adds no fill and does not clip, a component wrapped around layers is white and takes a single layer's name, and a boolean is filled like its topmost operand, or its base for Subtract, without strokes. The canvas commands and the plugin API now share the wrap parent check, stack ordering, component rules, and boolean paints, and the plugin API's createComponentFromNode converts groups in place as Figma does. Undoing a boolean returns each operand to its own place in the stack.
* refactor(core): reuse translate when centering pasted layers
* fix(app): animate menus, selects, and popovers as they open
The shared menu, select, and combobox content and the chat history and profile popovers appeared without motion; only tooltips and dialogs used the motion presets. A shared floating preset fades and scales them out of their trigger's side, and respects reduced motion.
They still close at once: during an exit animation the closing content kept focus, so a shortcut pressed right after choosing, such as undo, never reached the editor.
* feat(ai): compare a tool change's images with a split divider
The before and after images used a range input under a drawn line, and a second Compare/Highlight tab bar sat under the Changes/Input/Output one. A Reka splitter with the shared splitter handle now divides the two images, each drawn at the full width so the divider reveals one or the other, and highlighting the changed pixels is a toggle beside the changed-pixel share.
* feat(ai): name a run's earlier tool steps in its folded row
The folded row said only how many earlier steps a run took. It now lists them by name on one truncated line, with a count badge and a failure badge; its accessible name keeps the count.
* fix(ai): open tool calls to their full height at once
Reka measures a collapsible's content when it opens, but CodeMirror lays out its lines a frame later, and on the first call it was still loading. Every call animated to its height without the code and then snapped open, the first one further. LazyCodeViewer reserves the viewer's height from the line count before CodeMirror renders, and the card starts loading CodeMirror on hover or focus.
* fix(core): load fontoxpath under Node's ESM loader
fontoxpath is CommonJS, so Node exposes its exports only on default and openpencil query / MCP query_nodes failed with 'evaluateXPathToNodes is not a function'. Closes#787.
* test(tools): run an XPath query in the package runtime smoke check
The Bun-run unit tests take fontoxpath's named exports, so they never covered the Node fallback to default.
* test(tools): also run matchByXPath in the XPath smoke scenario
* refactor(core): import fontoxpath types through one namespace import

* fix(canvas): show every top-level frame's name and select frames by it
Since clicks follow Figma's depth, the empty part of a top-level frame
that holds layers selects nothing, but a frame's name was drawn and
hit-tested only while that frame was already selected. Once a top-level
frame held layers it could not be selected from the canvas, as when one
frame is dragged into another and the outer frame is then out of reach.
Every frame on the page or in a section now shows its name, faded in
the canvas's text color and in the selection color while selected or
hovered, from the same viewport-culled label catalog as section and
component labels. Its name is a hit target whether or not the frame is
selected, so clicking it selects the frame, dragging it moves the frame,
and hovering it highlights the frame; locked frames stay out of reach.
SkiaRenderer.hitTestFrameTitle no longer takes the selected IDs.
* fix(canvas): draw and hit labels whose node is just outside the view
Label catalogs culled nodes by their own bounds, but frame, section, and
component names sit outside the node, so a node just below the view hid
a name that was on screen and could not be clicked. Label lookups now use
the viewport widened by how far labels reach. Presses and hover also test
component labels, then section titles, then frame names, the reverse of
the order they are drawn, so overlapping labels pick the one on top.
* fix(fig): write text glyphs from the layout the renderer draws
Text without saved glyphs was written to .fig with outlines from a
character-by-character fallback: one unwrapped line at y = lineHeight,
no alignment, advances in pixels. Figma lays saved text out from that
data, so every wrapped OpenPencil label opened in Figma on one line, and
since saved glyphs now draw before the paragraph, OpenPencil did the same
after a reopen (#914). The Figma clipboard had a second writer with its
own shaping that matched outlines to characters by index.
One builder in @open-pencil/fig now writes derivedTextData for both. It
keeps glyphs a layer already has and otherwise asks the export runtime to
shape the text. Core shapes with the paragraph the renderer draws, so
lines, alignment, and baselines match, and takes each outline from the
glyph ID CanvasKit chose, so ligatures and contextual forms keep their
shapes. CanvasKit does not say which font drew a run, so outlines are
written only when the run's own font covers it; otherwise the layout is
written without outlines and readers lay the text out themselves.
Advances are in em units and the character offset map has one entry per
character, as in Figma's files.
The reader drops glyphs the earlier fallback wrote, recognised by its
offset map one entry longer than the text with every glyph on the one
written baseline, and any glyph set with a missing outline.
* fix(scene-graph): reflow resized text instead of stretching its glyphs
Resizing scaled a text layer's saved glyphs into the new box. That suits
path text, whose glyphs follow its path, but flat text reflows, and with
saved glyphs drawn before the paragraph a resized Figma text layer was
drawn stretched. Scale glyphs only for path text, including baked path
text that kept only rotated glyphs, and let the width change drop the
rest.
* docs(fig): describe how derived text is written
Figma draws saved text from derivedTextData even when it has the font, so the export docs record which glyphs the shared writer keeps, shapes, or leaves without outlines, and the units it writes. The README names the runtime service by what it now does.
* fix(fig): write text without glyphs when shaping fails
Glyphs are derived data, so a shaper error must not fail the .fig save or Figma clipboard copy that writes them. The builder now writes the layer without glyphs and logs a warning; the clipboard used to swallow the error silently, which hid a font-provider mismatch.
* fix(desktop): pin every command line the app may start
On Windows the app starts npm-installed CLIs through cmd /c, and the shell scope let cmd take any arguments, so any code running in the webview could run any command. Each program now has a scope entry with its exact arguments, and Windows shims go through their own cmd-<name> entries with fixed /c <name> arguments. The agents and the MCP server no longer accept arbitrary arguments either. A test checks that every command the app starts has a matching entry on both platforms.
* test(desktop): expect Windows shims through their own scope entries
* test(desktop): check the executable of each shell scope entry
* test(desktop): allow no shell scope entry beyond the programs the app starts
An extra entry with a permissive validator passed the per-program checks.
The Kiwi codec types only symbolID, so every test reading symbolOverrides
or uniformScaleFactor repeated the same cast against a type the package
exported without the readers that go with it. symbolDataOf and
symbolOverridesOf are now exported and five call sites use them.
tests/engine/library exercises @/app/libraries, so it belongs under
tests/app by the placement rules; the shard list and the engine baseline
follow it.
* fix: stop ancestor walks from hanging on a parent cycle
A collaborator's concurrent reparent can leave two layers as each other's
parent. isDescendant, the design check's pageOf, and component sync walked
parentId without a bound, so applying such a change froze the editor.
Add SceneGraph.closest(), a bounded nearest-ancestor lookup, and use it for
these walks so bad data ends the walk instead of the tab.
* fix(collab): sync layer moves without parent cycles or stale child lists
Remote changes assigned each layer's synced parentId and childIds as plain
properties. Two peers moving layers into each other made them each other's
parent, a moved layer stayed listed under its old parent, reorders never
synced, and concurrent additions ended up in different orders or missing
from the parent's list.
Apply the tree after a change's properties: move layers to their synced
parents, skip a move that would make a layer its own ancestor and write the
layer's current parent and position back so every peer settles on it, and
derive each touched parent's childIds from its synced order followed by
unlisted children by id. Locally, a parent's child list syncs once after
each edit that adds, removes, moves, or reorders its children.
Fixes#888Fixes#889
* refactor(scene-graph)!: move sibling order keys to scene-graph
Collaboration needs the same fractional keys as .fig export to order
siblings, and the app must not depend on @open-pencil/fig for them. Move
fractionalPosition, orderKeyBetween, and siblingOrderKeys to
@open-pencil/scene-graph/order-keys.
orderKeyBetween now always returns a key: when no printable key fits it
returns one above lo, which hasOrderKeyBetween detects, so callers no
longer branch on null. It takes an optional suffix, and siblingOrderKeys
can request one per key, so two peers inserting at one spot get distinct
keys. .fig export keeps its keys.
* fix(scene-graph): report instance child reorders as graph events
Instance sync sorted an instance's children in place, so nothing that
listens to graph events saw the new order; in a shared room the order
never reached other peers. Move each child that changes position with
insertChildAt, which reports the reorder.
* feat(collab): resolve the layer tree from each layer's parent history
Add a pure LayerTree for the shared document: each layer records every
parent it was moved under with a move counter and an order key. A layer
sits under its newest parent, ties broken by parent id; when concurrent
moves close a loop, the latest move in the loop falls back to the
layer's next entry until none is left, and a layer no parent can take
goes to its page (Evan Wallace's mutable tree hierarchy CRDT).
The result depends only on the entries, and resolution revisits only
changed, orphaned, and displaced layers. Seeded random runs check that
peers converge and that the incremental result matches a full one.
* fix(collab): sync layer moves as parent history and order keys
Each layer's shared map now records every parent it was moved under with
a move counter from a document-wide Lamport clock, and its order key
among siblings, instead of parentId and childIds. Every peer derives
parentId and childIds from these with LayerTree, so concurrent moves,
reorders, and additions merge, a loop from concurrent moves undoes its
latest move, and a layer whose new parent was deleted meanwhile returns
to its previous one.
A local edit's graph events are written once after the edit, in one
transaction. It records a parent entry for each layer whose parent
changed, a new entry for displaced layers on the touched paths so a move cannot pull
them back, and keys between the moved layers' neighbours with a random
suffix, so concurrent inserts at one spot get distinct keys. Remote
changes find their layers through each event's path, resolve only what
they touch, and move and sort layers through insertChildAt.
This replaces the childIds merge and the write-back of rejected moves:
a rejected move now resolves the same way on every peer from the shared
history, so nothing needs to be written back.

* feat(collab)!: convert saved rooms and keep mismatched builds apart
A room saved by an earlier build records parentId and childIds. When a
change brings in such layers, from this browser's storage or a peer,
convert them in one transaction: each layer's synced parent becomes its
only entry with counter 0, its position in the parent's synced childIds
becomes an order key, and the old fields go. The result depends only on
the document, so two peers converting at once write the same values,
and converting again writes nothing. The document's meta map records
treeFormat 2.
Builds that record the tree differently would corrupt each other's
rooms, so the collaboration namespace becomes openpencil/2 for Trystero
and the test relay alike, and each peer publishes its treeFormat in
awareness for future version messages.
* fix(collab): send a layer whose parents were all deleted back to its own page
Each layer's shared map records the page it was last placed on, and the
layers under a frame moved to another page are re-recorded. A layer whose
parent chain was deleted goes back to that page, falling back to the first
page only when the recorded one is gone. Saved rooms record pages when
they are converted.
* fix(collab): keep one root per room when peers edit their own documents
Joining a room keeps the joiner's earlier document in its graph, and an
undo or an edit made before the room arrived could still reach it. That
edit shared the joiner's root, every peer adopted it, and the room's
pages disappeared.
The room now records its root as claims in meta, each with the time it
was made, and every peer follows the earliest. Sharing claims the room,
and so does the first edit in a room nobody has shared, which now shares
the whole document as Share does. A peer shares only layers under the
room's root. Converted rooms claim the root with the most children.
Move counters must also be safe integers, so an oversized counter from
another peer cannot stop the move clock from advancing.
* fix(collab): rank root claims by how they were made, not by clocks
Root claims carried the claiming peer's wall-clock time, so a guest whose
clock ran behind the sharer's could still win the room with an edit made
before the room reached them. A claim now records whether it came from
Share or a converted room, or from the first edit in an unshared room;
a shared root outranks an edited one, and the lower id breaks a tie.
A claim also replaces an invalid value already stored for its root.
* fix(collab): keep every root claim through concurrent writes
A root claim was one key per root holding its kind, so two peers claiming
the same root by Share and by an edit at once kept only one of the two
values, and the shared claim could be lost. Each kind of claim on a root
is now its own key. Converting a saved room also claims its root unless
a shared claim exists, so a guest's earlier edited claim no longer keeps
the converted room from outranking it.
* fix(collab): mint layer IDs under a session of each editor window
Every editor window started its IDs at 0:1 from the same counter, so two
people adding layers to a shared room at once could mint the same IDs,
and one person's layers replaced the other's in the room. A joiner's
starting page also took the sharer's page ID and stayed in their list.
SceneGraph's default IDs now carry a session set with setIdSession, as
in Figma's sessionID:localID GUIDs. The editor picks a random 32-bit
session at startup, as Yjs does for each document's clientID; headless
tools keep session 0, so the CLI and MCP server give a file's layers the
same IDs on every run.
* fix(collab): let only Share set a room's root
A guest's first edit in a room whose contents had not arrived claimed
the room and wrote the guest's whole open document into it, images
included, and adopting the sharer's root later only hid it. Every room
starts with someone sharing a document, so a guest has nothing to claim:
only Share, or converting a saved room, now sets the room's root, as a
single value in meta, and a peer writes nothing until the root is known.
Unbinding a room also writes an edit still waiting to be sent, so a move
or deletion made just before leaving reaches the room.
* feat(collab)!: open each room in a tab of its own
Joining a room bound it to whatever tab was active, so a pasted link
could turn a saved file into the room's document, and a share link first
showed an editable blank document. A room is now a document: joining
always opens it in a new tab, or switches to the tab already showing it,
and only Share puts an existing tab's document into a room.
Every room tab owns its session (src/app/collab/rooms.ts and
session.ts), so several rooms can be live at once and keep syncing in
the background. The collaboration panel, presence, following, and the
/share/<id> address follow the active tab, and a canvas publishes its
cursor and selection only to its own tab's room.
A room tab derives its state: joining while its saved copy loads, then
waiting, with an explanation, while nobody who has the file is online;
live with others, or alone on this device's copy. Until the document
arrives the room's screen replaces the editor. Reloading a share link
rejoins it; leaving a room you joined keeps its file as a local unsaved
copy. "Connected" now means another peer answered. Pasted links and IDs
are normalised and validated, and invalid ones say so.
People join right away under a generated name such as "Teal Fox", with
a hint to set one; the one app-wide name is set in the share panel or
in Settings. On a phone, Share copies the room's link instead of making
a new room, and the presence popover shows the room's state.
* feat(desktop): open rooms from openpencil://join links and Home
The desktop app could not receive a share link: links point at the web
app, and openpencil:// only opened files. openpencil://join?room=<id>
now opens the room in a tab of its own. The native parser refuses
anything but a room ID, queues rooms for the frontend through
take_pending_rooms, and a second launch on Windows and Linux forwards
its link through the single-instance handler.
In a browser on a computer, the room's screen and the share panel offer
Open in desktop app, a link the browser hands to the app on click; it
never opens the app by itself. Home gains Join room…, which takes a
pasted room link or ID and opens the room in a new tab.
* feat(collab): set your name on the room screen
The room screen told someone joining under a generated name to set
their name but offered nowhere to do it before the file arrived. It now
has the same name field as the room panel.
* feat(collab): offer the desktop download beside Open in desktop app
A browser on a computer offers a room's openpencil://join link, which
does nothing where the app is not installed. The room screen and panel
now link to the latest release beside it.
* docs: describe joining rooms in the German, Polish, and Russian guides
Bring the translated collaboration pages up to the English one: Share as
the only way into a room, joining in a tab of its own, the waiting
screen, leaving with a local copy, and how layer moves merge. The
English page now names the panel's Leave room button.
* fix(collab): lay out the room screens like the app's empty states
The joining and waiting screens were a left-aligned card with a stray
spinner, a primary Copy link button beside an outline button and a
bare link, and a name field on a screen that lasts seconds. They now use
AppPlaceholder, centred over the tab: a heading, the explanation, the
two hints, secondary Copy link and Leave, a 'You'll appear as' line
whose Change opens a small rename popover, and the desktop handoff on
one muted line. The room panel lines its status dot up with wrapped
text, no longer selects the room link when it opens, and puts the
desktop links and Leave room on one footer line.
* fix(collab): show what a room tab is doing instead of a timed guess
A joined tab said nobody with the file was online five seconds after it
opened, whether or not it had reached the signaling service or met the
people already in the room. Its state now follows what the tab can
observe: connecting until the service answers, looking for people for as
long as that transport takes to introduce everyone, getting the file
from someone who says they have it, waiting when nobody who has it
showed up (naming other guests waiting too), and a can't-connect screen
when the service cannot be reached. Each peer says in its presence
whether it has the room's file.
* fix(collab): list other waiting guests with the explanation
The line naming other guests who are waiting too is information, not an
action, so it follows the hints above the buttons. Peers' hasFile flag
is optional, as older builds do not send it.
* fix(collab): send a canvas's cursor and selection to its tab's room again
Canvases read the editor through a proxy that follows the active tab,
and the room lookup by store never matched it, so pointer moves and
selections stopped reaching the room: collaborators lost each other's
cursors, selections, and page markers. The canvas now looks up its
room by its tab's own store, and its selection listener ends when the
canvas unmounts instead of piling up across tab switches.
* feat(collab): one avatar stack for the toolbar, the mobile pill, and pages
The toolbar, the page list, and the mobile HUD each drew the people in a
room their own way, and the mobile pill read 'Online: 3' in hard-coded
English beside a status dot too small to render. AvatarStack now draws
people overlapping with their agent counts and '+N', and every place
uses it: the toolbar wraps each avatar in its menu or hover card, the
mobile pill shows the room's state dot and the stack with a translated
name, and hovering a page with people on it opens a card with the stack
and who is there, with their agents, to follow. The mobile list is the
shared presence list, so it is translated and can follow agents too.
* docs: note the page hover card and mobile avatars in the changelog
* fix(collab): stop listening to a room once its tab leaves it
A session left its Yjs observers and its awareness listener attached
after dispose, relying on destroy() and the order of teardown not to
touch the tab again. It now removes them explicitly and clears its peer
list. Also fix a missing comma in the Polish collaboration guide.
bun audit reported a critical advisory in proxy-addr 2.0.7 (GHSA-jqcg-44mw-7w3h), reached through the Harness companion's Pi dependencies, which fails the dependency audit on every pull request. bun audit fix moves it and ten other transitive packages, including dompurify, qs, and undici, to patched releases within their declared ranges.
* feat(core): add visual diff and patch apply tools
diff_visual renders two nodes at one scale through the existing raster export, compares them with pixelmatch, and returns the diff PNG with the changed ratio and region in source-node coordinates. It takes export_image's scale and maxEdge inputs. FigmaAPI gains a CanvasKit-backed raster codec and a pageId export option, so the app and headless CLI decode pixels and render nodes off the current page.
diff_apply applies diff_create and diff_show patches through the Figma API, validates every node before changing any, and supports dryRun and force. diff_show now simulates changes on a detached copy with the same property code. One serializer and parser back all three. diffDocuments compares two documents page by page by name path.
Image tool results now reach models as media with their metadata as text, for any tool rather than export_image alone. diff_create, diff_jsx, and diff_visual join the default AI tool set, and the diff tools are no longer hidden from WebMCP.
* feat(ai): show what each AI edit changed in its tool call
Reviewing an AI run meant reading tool output or undoing steps to see
what moved. Each document-changing call now rebuilds its page before
and after from snapshots taken around it, and diffs each top-level
layer's JSX with jsdiff, the same patch diff_jsx returns, to find the
layers it changed. After the call returns, the changed region renders
in both states at one size and pixelmatch highlights the difference.
The tool card opens on a Changes view with a before/after slider, the
pixel highlight, and a CodeMirror merge view of the JSX. Records are
saved with the conversation next to attachments.
Calls snapshot their page individually instead of through one shared
variable, so concurrent calls in a step no longer overwrite each
other's undo state. Core gains graphFromPageSnapshot for rebuilding a
past page state, diffPageLayersJSX and jsxPatch (now shared with
diff_jsx), renderRegionToImage for rendering two states of one region
pixel for pixel, and comparePNGs on the raster codec. Settings > Chat >
Change previews sets the stored image size or turns images off.
* feat(cli): add diff commands and agent diff guidance
openpencil diff create, jsx, show, apply, and visual run the Core diff tools on a file or the running app; apply writes back with --write or --output like eval. diff files compares two documents page by page and exits 1 when they differ.
The chat prompt asks the agent to edit in place and to verify risky edits against a reference copy with diff_jsx, diff_create, and diff_visual. The skill, CLI reference, MCP tool table, and a new Comparing Designs page document the commands and tools.
* feat(ai): render tool calls as summarized, highlighted cards
Every tool call showed only a status and its output as a JSON string,
so render calls hid their JSX, export_image dumped base64, and long
runs filled the transcript with identical rows.
A call now shows a one-line summary read from its input and chips that
select and zoom to the layers it touched, switching to the run's page
when needed. Expanded, it shows the JSX or script it wrote and its
JSON input and output in a read-only CodeMirror view, and exported
images inline. Render calls can be expanded while their input streams,
so the JSX appears alongside the canvas preview. Consecutive calls
beyond three fold into one row that keeps the latest call visible.
CodeMirror loads with the first expanded call. The code theme gains a
monospace fallback because the editor font variable is not always
emitted.
* feat(ai): let the chat AI diff its run against the starting state
The diff tools compare two nodes, so checking an edit meant cloning a
reference first, which the agent rarely did. diff_changes compares the
current page, or one node under it, with the page as it was before the
run first edited it, in diff_create's patch format. The app keeps that
page snapshot per run and exposes it through FigmaAPI.changeBaseline;
MCP and WebMCP have no run, so the tool is offered only to the AI chat,
where it is enabled by default and the prompt asks for it before
reporting.
* feat(ai): revert, regenerate, and edit chat turns
A reply that went wrong could only be undone step by step from the Edit
menu, and asking again meant typing a new message on top of the old
edits. Each run now keeps the undo entries its document edits push, and
the reply offers Revert changes while those entries are still the
newest on the undo stack, so it never undoes an edit made since. The
last reply can be regenerated, and the last message without
attachments edited and sent again; both undo the replaced reply's edits
first when they can.
UndoManager gains peekUndo so a caller can tell whether its entries
are still on top, and turn state follows the store's history:changed
event. The submission's chat dependency narrows to the members it uses.
* feat(core): diff and patch node trees as JSX attributes
diff_create, diff_show, diff_apply, and diffDocuments used a hand-rolled
`key: value` property format that covered about fifteen properties,
matched children by name path, and could not see moves.
Nodes are now projected to the attributes the JSX export prints, and
jsondiffpatch matches children (by ID or by name path) and detects
moves. Patches list `-`/`+` attribute lines per node plus moved, added,
and removed children. diff_apply checks every hunk first, applies
attribute changes through the renderer's prop handling, and changes only
the fields an attribute moves, so IDs, instance links, and other state
survive. diff_show takes JSX attributes instead of a JSON props object.
design-jsx gains sceneNodeAttributes, parseJSXAttributes, and
jsxNodeFields for this, and the export round-trip property table is
shared so every case is also diffed and applied. `diff files` loads its
documents in order so node IDs, and so its patches, are deterministic.
* feat(ai): report diff_changes as a patch diff_apply can replay
diff_changes printed a unified diff of the JSX, which agents could read
but not apply. It now diffs the run's baseline against the live page
with the patch engine, matching nodes by ID, so a rename is a changed
name and the output replays on the starting state with diff_apply. The
chat's Changes view keeps the JSX line diff, which is for people.
* chore: format the merged AI tool exports
* fix(core): keep diff_apply atomic and diff files honest about differences
- Added nodes render before anything else changes; if one fails, for
example on a missing component, the rendered ones are deleted and
nothing else is committed.
- A hunk with an attribute the renderer ignores fails instead of
reporting "unchanged".
- diffDocuments reports `changed` from page statuses, and a page only
one document has gets its status but no patch, since patches do not
add or remove pages. diff files uses it, so an added empty page no
longer reads as a match.
- diff files rejects a --page neither document has and a --depth that
is not a non-negative integer, exiting 2; diff_create's depth is
validated the same way.
* refactor(ai): drop the unused tool JSON slot and place the JSX summary comment
* refactor(ai): find a tool change's clipping region with jsdiff
clipChangedJSX scanned both JSX sources character by character for their common start and end. diffLines gives the unchanged lines before the first change and after the last; the app now declares the diff dependency Core already uses.
* fix(ai): keep a turn revertable when it ends with a view change
Every mutating AI tool pushes an undo entry, but a turn recorded only those of tools that change the document. A run that closed with viewport_zoom_to_fit left that entry on top of the undo stack, outside the turn, so Revert changes never appeared and Regenerate did not undo the reply. The turn now records every entry its run pushes.
* test(ai): give the fake chat Chat's sendMessage signature
The test type check added in #896 rejects a fake whose sendMessage requires text; Chat's takes an optional message, and the fake reads only its ID.
* feat(ai): keep reverted replies marked and tell the model about them
Reverting a reply undid its edits and hid the button, so the chat still read as if the edits were there, and the model's next request still carried the tool calls and results that made them, so it could build on nodes that no longer existed. A reverted reply is now marked in its message metadata, which conversations store, and shows Changes reverted. The next request carries a hidden note, in the way referenced nodes are passed, for each revert no request in the history has reported; a resent message reports again what the message it replaces reported. Edit > Redo bringing the edits back removes the mark. The revert bookkeeping lives in submission/reverts.ts, and ChatInstance moves to submission/types.ts beside ChatSubmission.
* fix(ai): keep reverted replies cloneable so the chat still saves
Marking a reply copied the chat's reactive message, so the copy carried proxied parts and saving the conversation failed with DataCloneError on the revert and on every save after it. The message is unwrapped before it is copied. The unit test's chat now keeps messages in a deep ref like @ai-sdk/vue's Chat and saves them synchronously like the history does, which reproduces the error. A new browser test drives the app's own tool loop with a scripted model: it reverts a real render, checks the mark, the note in the next request, that the chat saves without errors, and that the mark is still there after reopening the conversation.
* feat(ai): restore a reverted reply's changes from the chat
A reverted reply only said Changes reverted, so bringing its edits back meant Edit > Redo. While nothing has been edited since the revert, the reply now offers Restore changes, which redoes exactly its edits; the existing Redo listener then removes the mark. Once other edits close Redo, the reply stays marked. UndoManager.peekRedo mirrors peekUndo, so a turn can tell its entries are the next Redo applies.
Both factories know what they built, but returned the bare proxy, so a
caller reading componentProperties, setProperties or isExposedInstance
had to narrow first — the instance surface is only spelled out on the
node types. Two test suites had each grown their own cast for it.
FigmaInstanceNode joins the other node types and is exported, and the
compatibility check names it instead of respelling the intersection.
Narrowing a return type is not a breaking change: a caller that held
the result as a FigmaNodeProxy still compiles.
* test(fig): pin override and variable precedence to what Figma renders
The rule that decides between a bound variable and an instance's text
override is not stated anywhere we control: an owner's consumption
entry binds the field when it carries variableData and clears it when
it is bare, and a binding beats a literal an outer owner recorded.
The archive is a six-node file authored in Figma for exactly these
cases, so the expected strings are Figma's own output rather than ours.
It replaces reaching for a 44k-record community file to check this.
* ci: pull the new fixture in the quick unit shards
The quick shards fetch an explicit list of small LFS fixtures, so a new
one arrives as a pointer and the fig shard fails parsing it.
A critical advisory for proxy-addr (GHSA-jqcg-44mw-7w3h), reached through the harness's MCP SDK and express, fails check:audit on every branch. bun audit fix moves it and ten other packages to patched versions inside their existing ranges.
The default generator counts 0:1, 0:2, … across the session, and a .fig
import keeps its own 0:N GUIDs. After opening a file with more than 1000
consecutive taken IDs ahead of the counter, creating a node threw "The ID
generator returned 1000 IDs in a row that are in use".
A generator can only be exhausted once it returns more taken IDs than the
graph holds, so the limit is now that count instead of a fixed 1000.
* fix(vue): release CanvasKit WebGL contexts when canvases go away
GetWebGLContext registers a canvas's context in CanvasKit's global
table, and the surface manager only called deleteContext on a failed
setup. Every destroyed canvas, and every surface rebuilt after a resize
or color-space change, stayed registered, and through the canvas
element CanvasKit kept the closed editor's component tree, store, and
graph alive.
The manager now keeps the handle and releases it on rebuild and
destroy. deleteContext also leaves CanvasKit holding the last current
context, so when the released context was current, a parking context
on a 1x1 offscreen canvas becomes current instead.
* fix(core): uninstall an editor's text measurer when it closes
setCanvasKit installed a global text measurer that closed over the
editor and its renderer, and nothing uninstalled it, so the last editor
to set up a canvas stayed alive after its tab closed and layout kept
measuring with its destroyed renderer. installTextMeasurer returns an
uninstall function; an editor uninstalls its measurer when disposed or
when its last renderer goes, and the most recent measurer still
installed takes over.
* fix(app): give editor stores their own effect scope
The first store is created during WorkspaceView's setup, so effects
created while building it joined the view's scope. Their cleanups
stayed registered there after the store was disposed and kept the
startup document alive for the life of the app. Stores now build inside
a detached effect scope that dispose stops.
* fix(app): follow the active tab in app-level editor subscriptions
App.vue provided a proxy that resolved to whichever store was active
when a property was read, so app-level composables such as the menu
and keyboard commands subscribed once to the startup store. They missed
events from later documents and kept that store alive, and Undo and
Redo availability came from the first document's history.
The app-level editor now moves event subscriptions to the active store,
and each tab's editor UI gets its own store through EditorTabScope, so
per-tab components stay bound to their document when it closes.
Selection capabilities read the undo history lazily instead of
capturing the first store's manager.
* fix(app): stop keeping closed documents in chat history and startup
The chat history kept the last editor it served only to compare it with
the next one; it now holds it weakly. WorkspaceView's first tab was a
top-level setup binding, which Vue keeps on the instance; it is now
block-scoped.
* test(app): check that documents closed in tabs are released
Opens a document in a new tab three times, closes each with discard,
forces garbage collection, and checks that weak references to the
closed graphs clear. On master all three graphs stay alive.
* refactor(app): provide the tab's store from a tab-keyed editor view
EditorTabScope existed only to provide a tab's store to its editor UI.
WorkspaceView now keys EditorWorkspace by tab, whose contents were
already remounted per tab, so the view provides the tab's store in its
own setup and the wrapper component goes away.
* fix(app): stop a store's effect scope when building the store throws
Effects created before the throw would otherwise stay alive with the partial store, which no caller can dispose.
* test(app): avoid empty callbacks in the store scope tests
* fix(harness): start Pi sessions with MCP tools under Node
The desktop app always gives Pi OpenPencil's MCP server, and the
published companion failed every such session:
- @ai-sdk/harness-pi imports pi-mcp-adapter, which publishes only
TypeScript sources, and Node refuses to strip types under
node_modules. A module load hook now strips them for TypeScript
dependencies only; Bun runs them as is. (vercel/ai#22040)
- pi-mcp-adapter imports @earendil-works/pi-tui but declares it as an
optional peer, so npm leaves it out. The companion depends on it at
the version pi-coding-agent uses, and a test keeps the two in step.
(nicobailon/pi-mcp-adapter#805)
- Pi reports live-process resume, yet the service handed it state
saved by an earlier session, and the just-bash sandbox cannot resume,
so every later session with that ID failed. Live-process backends now
start fresh and drop saved state.
Pi also installs the packages from a person's Pi settings with npm on
every session, writing npm's output to the companion's stdout. The
companion now keeps the real stdout for protocol messages, sends other
writes to stderr, and quiets npm on success. The app logs companion
stderr as diagnostics, since failures arrive as protocol errors.
* fix(harness): reject another backend's state before dropping it
loadResumeState removed saved state for a live-process backend before
createSession checked which backend owned it, so state saved by another
backend was lost instead of rejected. Ownership is checked first, and
only state that belongs to the live-process backend is dropped.
* perf(scene-graph): give imported nodes the shape every node shares
createDefaultNode had no default for booleanOperation, and the .fig
importer sets that key on every node. A key outside an object's initial
shape turns it into a JavaScriptCore dictionary, so every imported node
had its own structure and dictionary property storage. Fully loading
material3.fig took 3.7 GB RSS in Bun; with the default it takes 2.8 GB,
with 0.5 GB less JS heap and 0.46 GB less memory outside it. V8 keeps
these objects fast either way.
The defaults now must name every SceneNode field, which the compiler
enforces, and a test checks that imported nodes carry exactly the
default fields. booleanOperation states the explicit undefined the
importer already stores.
* fix(scene-graph): require booleanOperation and compare node keys in order
Every SceneNode field is required except booleanOperation, so a typed
producer could still omit it and build a node with a different shape.
It is now required, with undefined still meaning no operation. The
node-shape test compares keys in insertion order, since JavaScriptCore
lays out the same keys added in another order as a different shape.
The changelog entry no longer quotes the Bun measurement as figures for
the macOS app and Safari, and records the type change as breaking.
* fix(core): let fill text share an auto-layout row
Fill frames grow and shrink from a zero flex basis, so fill siblings split a row's free space. Fill text only got flexGrow, and its measure function capped it at its stored width, 100px for new text, so seven fill labels in a 280px row each kept 100px and overflowed. Without a measurer, the fallback pinned that width and set no grow at all. Fill text now uses the same zero basis as fill frames on both paths.
* fix(design-jsx): read repeat() and minmax() in grid tracks
Track lists were split on whitespace, so columns="repeat(7, 1fr)" became the tracks repeat(7, and 1fr), read as fixed 0px and 1px columns that collapsed the grid. Tokens inside parentheses now stay together, repeat() expands its tracks, minmax() grows like its maximum, and a track the grid cannot express sizes to its content instead of to 0.
* refactor(scene-graph): parse CSS grid tracks with postcss-value-parser
design-jsx read repeat() and minmax() with a hand-written tokenizer and regexes, while dom-css already parses CSS values with postcss-value-parser. Track lists are now parsed in @open-pencil/scene-graph/css on that library, where both packages can use it, and design-jsx calls it. dom-css's hand-written declaration of the library's types is replaced by the types the library ships, which the shared module needs. The Scene Graph guide records that CSS values are parsed there.
* fix(dom-css): read shadows, borders, and lengths with the shared CSS parser
dom-css tried each word of a shadow as a color and parseColor turned the leading 0 into black, so a shadow written in the usual order imported black, and the headless runtime split the border shorthand on spaces, which cut rgb(226, 232, 240) apart and also gave a black border. Numbers, colors, shadow lists, and shorthand parts are now parsed in @open-pencil/scene-graph/css on postcss-value-parser. Every shadow layer imports, inset ones as inner shadows, a fully transparent color counts as none, and lengths in units that depend on context, such as % or em, are no longer read as pixels. tryParseColor gives the color or null, and parseColor builds on it.
* fix(design-jsx): read the shadow prop as a CSS shadow list
The shadow prop was split on spaces, so a color before the lengths or a spread made the shadow black, and only one shadow could be set. It now takes a CSS box-shadow list through the shared parser, and pixel lengths in style props use the shared number parser. A rem grid track now has its size instead of sizing to content.
* test: type grid track and shadow fixtures
The test type check added in #896 rejects the grid track tests that #866 merged, because their object literals widen sizing to string, so bun run check fails on master. The fixtures are now typed GridTrack and Effect values.
* feat: open documents dropped onto the window
Dropping a .fig, .pen, or other readable document did nothing: the canvas drop handler places only images and SVG files and swallowed everything else. The workspace now opens dropped documents in new tabs through the same path as File → Open, passing the file handle where the browser provides one, and reports files it cannot open instead of ignoring them. Images and SVG files dropped on the canvas are still placed.
* fix: classify each dropped file instead of matching File identities
DataTransferItem.getAsFile() may return a new File, so checking it against the canvas files from dataTransfer.files could miss images and SVG files and open them as documents in engines other than Chromium. Each extracted file is now classified on its own; a spec checks that an SVG dropped on the canvas is placed without opening a tab.
* test: run each heavy unit test file in its own process
`test:unit` and `test:unit:heavy` ran every file in one `bun test`
process. A heavy fixture file alone takes 2-6 GB, and what one file
keeps stays alive for the rest of the run. Quick files still share one
process; heavy files now run one per process, so the peak is the
heaviest single file. Coverage runs keep one process, since coverage is
collected per process.
stale-overrides parses material3.fig and joins the heavy list, and a
guard fails when a quick test reads a large fixture corpus.
* test(core): keep one material3 graph alive at a time in stale-overrides
The edited-document test held the exported reader graph, the reopened
graph, and the parsed node changes at once, and the first test's graph
was still alive when the second started. Each step now runs in its own
function and returns only what the next check needs, and the file
collects garbage between steps and tests. The checks are unchanged;
peak memory drops from 5.6 GB to 3.6 GB.
* feat: name the call and list every problem in validation errors
Tool arguments were checked with v.parse, whose error names only the first problem and neither the tool nor the argument, so a model that sent a wrong create_shape call read 'Expected string but received 42'. Tool arguments in Core, which AI chat, MCP, the CLI, and WebMCP all reach, the automation bridge's file commands, design JSX component properties, and gradient stops now throw a heading that names the call followed by v.summarize, which lists each issue with its path. parseToolArgs is exported for the app's own parses of tool arguments.
* test(design-jsx): pass a deliberately wrong property value through the types
The test checks what a script sees for a non-string instance property, which the Instance types reject at compile time.
* docs: say that MCP clients get the MCP SDK's validation report
The MCP SDK validates tool arguments against the registered schema before OpenPencil's handler runs, so an MCP client already received every problem with its path and does not see parseToolArgs' message.
* fix(core): let fill text share an auto-layout row
Fill frames grow and shrink from a zero flex basis, so fill siblings split a row's free space. Fill text only got flexGrow, and its measure function capped it at its stored width, 100px for new text, so seven fill labels in a 280px row each kept 100px and overflowed. Without a measurer, the fallback pinned that width and set no grow at all. Fill text now uses the same zero basis as fill frames on both paths.
* fix(design-jsx): read repeat() and minmax() in grid tracks
Track lists were split on whitespace, so columns="repeat(7, 1fr)" became the tracks repeat(7, and 1fr), read as fixed 0px and 1px columns that collapsed the grid. Tokens inside parentheses now stay together, repeat() expands its tracks, minmax() grows like its maximum, and a track the grid cannot express sizes to its content instead of to 0.
* refactor(scene-graph): parse CSS grid tracks with postcss-value-parser
design-jsx read repeat() and minmax() with a hand-written tokenizer and regexes, while dom-css already parses CSS values with postcss-value-parser. Track lists are now parsed in @open-pencil/scene-graph/css on that library, where both packages can use it, and design-jsx calls it. dom-css's hand-written declaration of the library's types is replaced by the types the library ships, which the shared module needs. The Scene Graph guide records that CSS values are parsed there.
Four of the last five branches conflicted only on the changelog, each
time because two branches appended a bullet under the same heading.
Git's union driver combines them; it concatenates blindly, so the
existing de-duplication pass after a merge is what keeps the section
honest.
* build: typecheck the test suites
Tests were in no TypeScript program: no tsconfig included tests/** or
packages/*/tests/**, and bun strips types without checking them, so a
fixture could drop a required field and keep passing until something
read it.
@types/bun moves to the root because it was installed per package only,
and #cli-tests/* joins the paths the root config already carries.
* test: fix the type errors the test suites were hiding
Typechecking the tests turned up 1123 errors. Most were ordinary
strictness, but some were real: `NodeChange` bound to Figma's plugin
typings rather than the Kiwi codec in thirteen .fig tests,
materializeInstance was called with six arguments against five so the
blobs and source children were dropped, CanvasKit pixels were written
to a plain object that never reached WASM, and assertions were made
through accessors that do not exist, so they asserted nothing.
Fixtures that had quietly lost a required field now carry it, nullable
results are narrowed through the existing expectDefined helper rather
than assumed, and stand-ins for CanvasKit and the editor go through one
named helper instead of an unexplained cast at each site.
No test was deleted, skipped, or weakened, and no `any`, non-null
assertion, or ts-expect-error was introduced.
* docs: record what typechecking the tests established
Pins the app program's global types with an assertion rather than a
note, since an unpinned types list lets any root @types package decide
which platform src/** is judged against.
The two environment faults that look like code regressions — Vite's
dependency pre-bundle outliving a package rebuild, and heavy .fig
suites failing under load — go to the development docs, where an
explanation belongs.
* fix: align @types/bun and keep node types resolvable when extended
The root manifest declared a newer @types/bun than every package, which
check:monorepo rejects, and pinning the app program's types left them
unresolvable from a config that extends this one out of tree.
* fix: fail the test typecheck when the compiler itself fails
The gate matched diagnostics by substring, so a compiler or config
failure that named no test file printed a pass while having checked
nothing. Diagnostics are now split by whether they name a file: an
unscoped one is the run failing and stops the gate, a test file's is a
finding, and a source file's stays out by design.
Also drops the parameter planComponentConstruction never read, and
makes the inner-shadow verification script exit non-zero when it
renders no image instead of logging and succeeding.
* chore: merge master into tests-typecheck
* feat: select layers at Figma's click depth
Checked against Figma desktop 126 with the same pointer input in both
editors. A click walks from the page down to the deepest layer under the
cursor and stops at the first layer that is not open: top-level frames
(on the page or in a section) and sections that hold layers, component
sets, and every ancestor of the selection are open. So a click inside a
top-level frame selects its direct child, the empty part of a top-level
frame or section selects nothing, and a selected layer's siblings and
cousins are one click away. Double-click goes one level deeper and
Cmd/Ctrl-click reaches the deepest layer.
A marquee started inside a top-level frame or section selects that
container's layers; from the page, a frame or section holding layers is
selected only when fully enclosed.
* fix(vue): compare marquee hits by canvas bounds
A marquee scoped to a rotated frame mapped only two corners into its space, and page-level enclosure used a frame's unrotated rectangle. Both now compare each layer's axis-aligned canvas bounds with the marquee, so rotated frames and their children are selected by what is drawn.
* fix: match Figma when dragging, drawing, duplicating, and pasting
Checked against Figma desktop 126 with real pointer input. A dragged layer
lands in the topmost unlocked frame, section, component, or instance under
the cursor, following rotation and clipping, and leaves its frame as soon as
the cursor does; groups, boolean operations, component sets, and locked
frames never take a drop, and a layer stays in its group unless it lands on
another frame. Space keeps parents, Shift locks an axis, and Control drops
into auto layout as an absolute-positioned layer. Locked layers stay put.
New shapes go into the frame under the start point, frames and sections take
in the unlocked siblings they fully cover, duplicates land in place (top-level
frames to the right), and paste keeps the copied position, centering an axis
that does not fit the selected frame.
* fix: match Figma for drag edge cases with components, groups, and auto layout
A second round of checks against Figma desktop 126, replaying the same
pointer input in both editors. A component set takes back only its own
variants, and components never go into other components. Groups and
booleans refit their children after a move or nudge, and a group whose
last layer leaves is removed. Pressing inside a selected frame, group, or
component set drags it instead of the layer under the cursor.
Auto layout children dragged out land where they are dropped, drawing
inside auto layout adds to the end of the flow, and wrapped frames insert
on the line under the cursor. Duplicates keep their names, and a main
component duplicates as an instance with Cmd+D or Alt-drag; a multi-layer
duplicate stays in place, and a lone frame in a section counts as
top-level.
* fix(core): refuse new shapes in the locked part of an instance
createShape redirected a refused parent through acceptingParent while keeping coordinates in the original parent's space, and still inserted the layer when the slot claim failed. It now takes the given parent, claims a slot when needed, and throws when the parent refuses children; drawing skips such parents before creating anything.
* chore: prefer es-toolkit helpers and lint the mechanical cases
AGENTS.md now names the es-toolkit helpers to reach for instead of hand-written equivalents, and the exceptions: a single clear native call or a measured hot path. The new open-pencil/prefer-es-toolkit rule rejects filter(Boolean) and Set round trips on arrays, the two cases that need no type information, and the existing 45 sites use compact and uniq. tools/ci/policy runs before dependencies are installed, so the rule is off there.
* refactor: deduplicate diagnostic categories with uniq
* fix: keep es-toolkit out of serialized Playwright callbacks
The codemod rewrote a filter(Boolean) inside a page.evaluate callback, which Playwright runs in the page where the compact import does not exist. The spec filters there again, and the rule now skips callbacks passed to evaluate, $eval, $$eval, evaluateHandle, addInitScript and waitForFunction, and filter calls on iterators from values, keys, entries and matchAll, which compact cannot take.
* test: write the prefer-es-toolkit cases like the other rule tests
Short standalone snippets, as in the base64 and JSON rule tests, instead of a declaration prefix on every case and inline object types.
* feat: write variable-bound properties as tokens in exported code
HTML and Tailwind JSX export reference the design tokens a layer is bound to, var(--color-primary) or bg-primary, instead of baking in their values. A binding becomes a reference only where the stylesheet resolves it as the canvas draws it: the layer still draws the value, the token's unit fits the property, and an attribute such as data-theme="dark" can put the element in the layer's mode. Standalone HTML includes the stylesheet for the tokens it uses, compiled into Tailwind's @theme for Tailwind pages.
* refactor: share the collection variable list and tighten token helpers
Read every variable in collection order through one collectionVariables helper built on es-toolkit's compact, used by the stylesheet and the token references, and map padding sides and color channels instead of repeating them.
* fix(scene-graph): apply an instance's assignment to a late child
A component can gain a property-driven layer after an instance of it
exists. Cloning that layer copied the component's default and nothing
resolved the assignment the instance already made, so the layer showed
the default while the rest of the instance showed the assigned value.
Closes#849.
* fix(scene-graph): scope a property lookup to the component that defines it
An instance of a component that defines the id owns that reference even
when it assigns nothing, so the walk stops there instead of reaching an
outer instance's unrelated property of the same id.
Reported in review of #884.
* test(scene-graph): group the component property tests in a folder
Three siblings sharing the property- prefix is the domain-folder rule's
trigger; check:arch flags it.
* fix(scene-graph): resolve a property's owner through the instance chain
Only a component set's definitions reach its variants, so a component
nested in an ordinary component no longer claims the outer component's
property. An instance's link can point at another instance, so the
owner is resolved by following that chain to the component.
Reported in review of #884.
* feat(scene-graph): let a SceneGraph take its ID generator
The constructor accepts an ID generator, used for the root node and for
nodes, variables, and collections created later; generated IDs skip any
node, variable, collection, or mode ID already in the graph.
Refs #770
Signed-off-by: Marc Went <marc@went.io>
* perf(scene-graph): check mode IDs without allocating per created entity
Generating an ID spread every collection into a new array and scanned it
for each candidate, which runs on every createNode. Check the node,
variable, and collection maps first and walk the modes with an early exit.
An index of mode IDs is not kept because history snapshots, transfer, and
undo replace collection maps and edit modes in place, which would leave it
stale.
* test(scene-graph): cover injected ID generators and collision skipping
* docs: note the SceneGraph ID generator in the changelog
* test(core): keep reopened .fig GUIDs when a sibling is inserted before them
Refs #770
* test(collab): cover concurrent additions, same-property writes, and delete versus edit
Move the synced-store harness to tests/helpers/collab so the new cases
live in tests/app/collab, and let it bind graph events as a collab session
does. The cases edit both peers while disconnected and check the
converged graphs.
Refs #770
* fix(scene-graph): keep a collection's IDs apart and stop on an exhausted generator
createCollection asks for the collection and default mode IDs before
registering either, so a generator repeating a candidate gave both the
same ID. A generator that only returned taken IDs looped forever, even in
the constructor; it now throws after a bounded number of attempts.
* test: require the inserted GUID and a real disconnect in new tests
The GUID test passed even if export dropped the inserted layer, and the
concurrent-edit helper would have tested sequential sync had its peers
not been disconnectable.
* feat(scene-graph): create variable modes through the graph's ID generator
The editor minted added and duplicated modes as mode:<random hex>, so an
injected generator governed every graph entity except modes added after
a collection's first. SceneGraph.createMode mints the ID and adds the
mode; undo and redo replay it with addMode.
* test(core): type the reopened .fig buffer in the GUID test
* refactor(scene-graph)!: share random helpers and one component property ID
randomHex, randomInt, and randomIndex move from @open-pencil/core/random
to @open-pencil/scene-graph/random, so format packages can use them:
design-jsx and the MCP test server dropped private copies. Component
property IDs, written as prop:<random hex> in six places across Core and
design-jsx, come from createComponentPropertyId.
* docs: point the randomness rule at the shared ID and random helpers

* feat(app): record runtime errors in diagnostics with their stack
Uncaught errors and unhandled rejections only showed a toast, Vue component errors after boot only reached the console, and a failed chat kept just its error name, so a failure like WebKit's 'Attempting to define property on object that is not extensible.' left nothing to diagnose. They now record a runtime.error, and chat.failed its code, message, and stack. Messages and stacks are scrubbed of URL queries, key- and token-like strings, and home folder names and bounded; AI SDK and provider errors keep no message, since it can quote prompts or responses. Copied diagnostics start with the app version, shell, browser, and language.
* feat(app): label, filter, and page diagnostics events
Every row in Settings → Diagnostics read 'Technical event': the summary looked labels up under diagnostics-prefixed keys the messages do not have, and only a few event kinds had labels at all. Each event now has a specific label and a short detail, such as 'Tool: render · 162 ms', 'Model step · <model>', or an error's message, expands to its recorded fields and stack, and the list filters by level and category and grows a page at a time. The copy action passes the environment header, which moves out of the recorder so tooling that compiles it needs no build-time globals.
* test(app): stream a reasoning reply in WebKit without page errors
Errors such as WebKit's "not extensible" TypeError appear only in that engine, so run a streamed reasoning reply there and fail on any page or console error.
* fix(app): scrub queries on bare paths in diagnostic errors
Only URLs had their query removed, so a message like 'Failed to load /Designs/app.fig?token=…' kept the token.
* fix(app): count diagnostics recorded before Settings opens
The event count and size updated only on new events, so the panel showed 0 events beside a full list.
* feat(app): record failed AI tool calls as problems, with the stack of engine errors
A tool catches what it throws and returns only the message to the model, so diagnostics saw a failed tool as an info event without details. The adapter now passes the thrown value to the tool log. A failed call is a warning; a TypeError, ReferenceError, or RangeError, which comes from a bug in OpenPencil rather than a wrong call, is an error with its message and stack. Other tool errors keep only their name, since their messages quote layer names and arguments.
* fix(core): log tool calls that return an error as failed
Most tools report a failure by returning { error } rather than throwing, such as describe with an unknown node, so the tool log and diagnostics counted them as successful calls while the chat showed them failed.
* feat(app): scrub cloud keys, JWTs, private keys, URL credentials, and emails from diagnostics
The scrubber caught keys by shape only, so 20-character AWS access key IDs, user:pass@ in URLs, and emails reached the log, and a JWT's payload survived because its dots split it into short runs. It moves into its own module with rules grouped by what they protect. The added credential formats follow gitleaks; keys the shape rules already catch, such as GitHub, OpenAI, Anthropic, and Stripe ones, get no separate rule. No maintained browser library fits: secretlint needs Node built-ins and adds at least 23 KB gzipped, and the PII redactors miss tokens. The scrubber is 0.8 KB gzipped.
* refactor(app): name how a tool call is recorded and import diagnostics from its index
* fix(app): record demo document loads in diagnostics
The preparation event's schema listed its kinds, phases, cancel reasons, and failure codes by hand and lacked demo-load, so every demo load failed validation and was dropped. The schema now validates against the same lists the preparation types derive from.
* feat(app): label document preparation events in Settings diagnostics
Preparation events showed their raw name, editor.preparation.finished, because the summary had no label for them. They now read as their kind, such as Switch page, with the outcome and duration below. Event names are a typed union and the labels a map keyed by it, so recording a new event without a label fails type-checking; names stored by older versions still fall back to the raw name.
* fix(app): keep source paths and scrub provider stacks, auth headers, and spaced home folders
Review follow-up. A provider error's message was dropped but repeated on its stack's first line, so it is now removed there too. The long-run rule redacted source paths of 40 or more characters, losing the failing file; a run with slashes now loses only its key-like segments. The bare-path query rule cut optional chaining such as a.b?.c and now needs name= after the question mark. Authorization header values in any scheme, credential assignments such as api_key= or password:, and home folder names with spaces are now scrubbed.
* fix(app): suppress repeats of alternating runtime errors
Repeat suppression compared each error only with the previous one, so a loop alternating between two errors recorded every occurrence. Recent errors are now kept in a small bounded map.
* test(app): validate copied diagnostics and wait for the copy to finish
Master now rejects JSON.parse with a type assertion, so the copied report is read through a Valibot schema. The uncaught-error test read the clipboard before its copy finished and could see the previous test's report; it now waits for the confirmation, as the export test does.
* fix(ci): keep the review guidance script free of dependencies
The PR review guidance workflow runs the script with plain Node from the default branch without installing packages, so the Valibot import added with the JSON validation work failed with ERR_MODULE_NOT_FOUND on every review and comment event. The script parses the event and pull request by hand again, accepting the null fields GitHub sends, and a test runs it under Node with nothing installed.
* fix(ci): install the review guidance tool's dependencies instead of avoiding them
Restore the Valibot schemas and declare valibot in the tool's manifest. The workflow now installs the tool's workspace from the default branch's frozen lockfile with the shared setup-bun action and runs the script with Bun. The event schema accepts the null fields GitHub sends for absent values.
* fix(design-jsx): say what gradient helpers expect when stops are not an array
An AI agent called linearGradient with something other than an array of stops, and render failed with 'stops.map is not a function', which does not tell it how to fix the call. The helpers now validate their stops with Valibot and name the expected form, and the authoring reference shows the signature.
* fix(design-jsx): describe stops that cannot be shown as JSON
Review follow-up. JSON.stringify throws on a bigint or a circular object, so such a call failed with that error instead of the gradient's expected form.
* fix(design-jsx): word gradient stop errors from the Valibot issue
Review follow-up. The message now names the helper as a call, as the paint helper option warnings do, and ends with Valibot's description of what was wrong, which already says what it received without serializing the value. A stop that is neither [color, position] nor { color, position } names both forms and its index.
* feat: write variables as a CSS token stylesheet
Copy a collection as CSS custom properties or a Tailwind v4 theme from the variables dialog, print it with openpencil tokens, and rebuild design_to_tokens on the same generator. Default modes go in :root or @theme, other modes override under their condition, and aliases are declared again in each mode scope so they follow it.
* fix: give modes that slug alike their own selector and variant
Two modes in one collection whose names reduce to the same slug, such as Dark and dark!, shared one default selector and Tailwind variant, so the later mode silently overrode the earlier one. Slugs are now numbered in mode order, as variable names already are.
* fix: validate parsed JSON at untrusted boundaries with Valibot
Clipboard HTML, library revisions from shared storage, MCP and automation
WebSocket messages, the MCP discovery file, sidecar output and AI/MCP tool
arguments were JSON.parse'd and cast to their expected types, so a
malformed payload reached the document or crashed paste. They now go
through v.pipe(v.string(), v.parseJson(), Schema), which reports bad JSON
and a wrong shape as the same validation failure.
The path_set tool rejects an invalid VectorNetwork and shares its parser
with create_vector. The CLI library catalog validates its files and runs
revisions through the same size, identity and content-hash checks as the
app; reading image bytes as index-keyed records also stops them coming
back empty. Hand-rolled typeof readers for plugin data, document metadata,
caches and preferences become schemas with their behaviour preserved, and
readCacheJSON takes a schema for its payload.
open-pencil/no-unvalidated-json-parse rejects type assertions on
JSON.parse results other than `as unknown` in src and packages/*/src.
* refactor: validate parsed JSON in tests and tooling
Extend open-pencil/no-unvalidated-json-parse beyond source: tests, helpers and repo tooling now parse JSON through Valibot schemas instead of asserting a type. The shared fixture reader returns a validated object; its old array annotation never matched the fixtures.
* refactor: define OpenPencil plugin data in one typed registry
Every plugin-data key OpenPencil writes is now a field of OPEN_PENCIL_PLUGIN_DATA in scene-graph, with the Valibot schema that reads it; readPluginData and withPluginData replace per-key constants, JSON.parse and hand-matched pluginId/key filters across fig, core, and vue. Moving OkHCL onto it fixes picking a colour rewriting the layer's other plugin data as OkHCL entries.
* feat(app): add slot property controls and a shared picker
AppPicker is a searchable, grouped list that opens beside the properties
panel, built on Reka's popover and listbox so search keeps arrow-key
navigation. It has comfortable rows with a thumbnail and description and
compact rows for plain names, plus an optional footer action.
The slot property row shows whether an instance's slot is Default or
Modified, its item count, its limits with a checklist popover, Add
instances on AppPicker, and Reset slot and Delete contents. These are
presentational; wiring them to the editor follows. Strings are English
only until the locale files catch up.
* feat(app): open variable, style, and instance-swap choices in the shared picker
The variable binding picker, the shared style fields, and instance-swap
properties now open AppPicker: a titled panel beside the properties panel
with search that keeps arrow-key navigation, a check on the current
choice, and footer actions. Variable binding keeps its detach and
create-variable actions. Instance-swap choices list the property's
preferred components first; instanceSwapOptions keeps the preferred flag
it already computed. AppPickerField gives select-shaped fields the same
picker with a combobox trigger.
* feat(core): edit instance slot content
Only an instance's slots take layers now. slotScope classifies a parent as
free, a slot of an instance, or the locked rest of an instance. Moves,
reorders, layer-panel drops, paste, duplicate, and instance creation
claim an untouched slot first, as Figma does on the first edit, and
refuse the locked part; drops over it land in the instance's parent.
Claiming keeps the layers but unlinks them from the component and moves
the instance's overrides on nested instances onto those instances.
Reset slot, Delete contents, and Add instance are editor actions, each
one undo step that restores the instance's subtree. A canvas drop or
reorder that claims a slot undoes together with the move.
* feat(app): show and edit slot properties of the selected instance
The component properties section lists each slot of the selected instance
with its state, item count and limits, and adds instances, resets or clears
its content through the editor's slot actions. The slot model lives in the
Vue SDK as useSlotProperties.
* feat(app): outline slots on the canvas and mark them in the layers panel
Hovering or selecting a component, an instance, or a layer inside a slot
draws its slots with a dashed pink outline and tints empty ones. Slot
frames are selected and hovered in pink and show a dashed-square icon in
the layers panel.
* test(app): cover slot outlines with canvas snapshots
* feat(app): translate slot and picker strings
* docs: note slot editing and the shared picker
* refactor: share slot test and story setup
* refactor(app): name the picker's header prop heading
* feat(core): create, configure, and remove slots on main components
A frame of a main component becomes a slot through a SLOT property
named after it; other sibling layers are first wrapped in an auto
layout frame. Slot settings and removal are single undo steps.
Instances now follow the component's property bindings on sync, so a
slot created or removed on the component reaches existing instances.
Slot helpers move to a slots domain folder in Scene Graph and Core.
* feat(app): create and configure slots from the menu and properties panel
Create slot joins the canvas context menu for layers of a main
component. A Slots section on main components and their frames
renames slots, sets their description, layer limits, and preferred
components, and removes them.
* fix: keep slot claims in the same undo step and refuse wraps inside instances
Creating an instance and pasting HTML now batch the slot claim with the
edit. Undoing an added slot instance restores the previous selection.
Grouping or wrapping layers in the locked part of an instance is
refused, and a section that cannot move no longer claims a slot. The
picker clears its search however it closes, and its close and slot
actions labels are translated.
* feat(core): create and inspect slots through the plugin API
component.createSlot() adds a 100x100 frame named Slot, Slot 2, and so
on, bound to a new SLOT property, as live Figma does. Slot frames read
type SLOT, resetSlot() restores an instance slot's component content,
and limitViolations reports BELOW_MIN, ABOVE_MAX, and
HAS_NON_PREFERRED for instance slots. addComponentProperty and
editComponentProperty take a description and slotSettings, a cloned
slot is a plain frame, and componentPropertyReferences uses property
keys in both directions. The limit checks move to Scene Graph so the
Vue SDK and the plugin API share them.
* fix: keep nested slot content across swaps and read nested instance properties
A nested instance points at the instance it was cloned from, so its
component properties resolved to nothing. Properties now resolve through
those links to the main component, and a swap or variant switch parks
the slot content nested instances own and restores it into nested
instances of the same names, as live Figma does. Plugin appendChild and
insertChild claim the slot they add to and refuse the locked part of an
instance with Figma's error.
* test(core): record resetSlot on a main component slot; fix the Slots roadmap row
* fix(core): refuse deleting layers outside an instance's slots
As in Figma, delete and plugin remove() leave an instance's own layers
and its slot frames alone, while removing slot content claims the slot
in the same undo step as the delete.
* test(app): wait for the bulk rename dialog to close before the next shortcut
* feat(app): unify add, remove, and settings controls in the properties panel
A section's + adds an item and a row's - removes it everywhere: grid
tracks and variant properties now follow the fill and effect lists, and
the header + of a component set adds Property 1 ready to rename instead
of an inline form. Removing a variant is Delete, as for any layer.
Row settings share the sliders icon, the variables button opens with
its own icon, every icon button requires a label, and the instance
header buttons use sentence case. Create Slot joins the app menu.
* docs: note the unified properties panel controls
* feat(app): animate floating panels alike and share the severity icon
Popovers, menus, selects, comboboxes, and pickers now fade and grow in
from the side they open on and fade out on close, from one motion
preset that respects reduced motion; tooltips keep the tooltip preset.
SeverityIcon and its colours move from the design check to shared
feedback UI, and slot limits use them, so a broken limit reads like a
design-check warning.
* docs: note consistent popover and menu animation
* feat(app): give every floating panel one surface and close it at once
Popovers, menus, selects, comboboxes, pickers, presence cards, chat
history, and the issue tooltip share one rounded surface with a 1px
ring that outlines it in both themes; one-line tooltips keep a compact
shape with the same edge. The select theme's radius and elevation
options and local shadow overrides are gone. Panels still grow in from
their side but now close immediately: a fading modal menu kept blocking
the canvas and shortcuts until it unmounted.
* fix(app): keep a reopened context menu open and name option-drag undo Duplicate
Closing the canvas menu hands focus back to the canvas; when that
landed just after a quick reopen, the new menu closed as focus moved
outside it. Shortcuts no longer wait for a panel that is already
closing, and an option-drag duplicate that claims a slot is undone as
Duplicate rather than Move.
* test(app): wait for menus and popovers to close before the next key
* fix: validate parsed JSON at untrusted boundaries with Valibot
Clipboard HTML, library revisions from shared storage, MCP and automation
WebSocket messages, the MCP discovery file, sidecar output and AI/MCP tool
arguments were JSON.parse'd and cast to their expected types, so a
malformed payload reached the document or crashed paste. They now go
through v.pipe(v.string(), v.parseJson(), Schema), which reports bad JSON
and a wrong shape as the same validation failure.
The path_set tool rejects an invalid VectorNetwork and shares its parser
with create_vector. The CLI library catalog validates its files and runs
revisions through the same size, identity and content-hash checks as the
app; reading image bytes as index-keyed records also stops them coming
back empty. Hand-rolled typeof readers for plugin data, document metadata,
caches and preferences become schemas with their behaviour preserved, and
readCacheJSON takes a schema for its payload.
open-pencil/no-unvalidated-json-parse rejects type assertions on
JSON.parse results other than `as unknown` in src and packages/*/src.
* refactor: validate parsed JSON in tests and tooling
Extend open-pencil/no-unvalidated-json-parse beyond source: tests, helpers and repo tooling now parse JSON through Valibot schemas instead of asserting a type. The shared fixture reader returns a validated object; its old array annotation never matched the fixtures.
* fix: validate clipboard geometry bytes, library images and model catalogs
Clipboard geometry blobs and library image bytes must be bytes at contiguous indexes, so out-of-range or gapped values are rejected instead of silently becoming different geometry or images; serialized library nodes must carry source metadata. The models.dev and OpenRouter responses are validated like their cached copies, and activate-tab rejects a CDP frame it cannot read instead of hanging.
* refactor: extend the JSON validation lint to .json() results
no-unvalidated-json-parse now also rejects type assertions on Response, Bun.file and shell .json() results, the same unchecked parse in another form. MCP server tests read /health through a validated readHealth helper and discovery files through parseDiscoveryInfo; the remaining tooling reads its JSON through schemas.
* test: validate the RPC request body in the CLI app export test
* test: validate CLI JSON output in the tool and app command tests
* test: compare the malformed models.dev fallback with the curated list
Eleven translated pages changed in English since the last release without
matching updates: system requirements, the Lint tab, AI chat diff tools,
collaboration with agents, design JSX imports and export fidelity,
Storybook and live-app export, lint fixes, page navigation, and Checking
Designs. Bring de, es, fr, it, pl, and ru up to date, add the sections
the abridged translations lacked where a change landed, use each
language's UI labels, and point the export page at documents list.
