* fix(app): record MCP and CLI structural edits as undo steps
The automation bridge ran non-atomic tools, render, and eval without an
undo entry, so Edit > Undo could not revert layers an MCP client or the
CLI created, deleted, or rearranged. Snapshot the page around these
edits as the AI chat does, and skip the entry when nothing changed so
read-only scripts leave the history alone.
* feat(app): activate documents, undo, redo, and change settings over automation
Add activate_document, undo, redo, get_settings, and update_settings to
the app's automation bridge. Settings cover appearance, snapping, canvas
rendering, recovery, and chat preferences, validated with Valibot and
applied through their owning stores; credentials, models, MCP
connections, storage, and tool access stay out of reach.
* feat(mcp): expose document activation, history, and settings tools
* feat(cli): manage documents, history, settings, and tools in the running app
Turn documents into a command group (list, open, new, save, close,
activate), add undo, redo, and settings get/set, and add tool
list/describe/call so every MCP tool runs from the shell, against the
running app or headlessly on a file.
* docs: document app control from the CLI and MCP
* fix: never prompt in the app from automation closes and saves
close_file opened the app's Save changes dialog, which an agent cannot
answer: the call timed out and the dialog stayed open. It now fails on
unsaved changes unless the caller passes unsaved "save" or "discard"
(CLI --save or --discard). save_file and new_document no longer open a
Save dialog for a document that was never saved, report a failed save
as an error, and leave the document untouched when the path is refused.
* docs: describe non-interactive close and save
* fix: address review findings in app automation
Keep a document's source when a save to a new path fails, report
vector-edit undo and redo no-ops as unapplied, echo only the applied
patch from update_settings so writing cannot read settings, reject
tool call --write/--output without a file, and stop settings get from
following inherited keys.
* fix(app): record render undo on the page that receives the layers
A render into a parent on another page was snapshotted against the
target page, so undo left the new layers in place. Snapshot the page
that contains the parent instead, and document that eval edits made
after switching pages stay outside the undo step.
* feat(app): limit automation undo to its own steps and expose design check settings
The undo history is shared with the person in the editor, so an agent's
undo could revert the user's last edit. Automation undo and redo now act
only on steps made through the bridge, and only while they are newest;
otherwise they fail and leave the history alone. Vector edit mode's
session history is off limits entirely. Settings automation also covers
the design check preferences that landed on master.
* build: update dependencies
Update the AI SDK providers, Vue, Reka UI, Valibot, Zod, es-toolkit,
CodeMirror, Storybook, Playwright, Hono and other dependencies to their
current releases, consistently across workspaces.
The Tauri plugin packages must match their Rust crates, and the new plugin
crates require Tauri 2.12, so Cargo.lock, @tauri-apps/api and the Tauri CLI
move to 2.12 as well.
* build(harness): update the AI SDK harness packages
@ai-sdk/harness 1.0.74 pinned ai 7.0.67, so the workspace carried a second
copy of ai next to the root one; 1.0.138 depends on the same ai release.
The Pi adapter no longer takes a model: HarnessAgent does. The settings
were spread from untyped records, so the compiler could not reject the
stale key and the chosen model would have been dropped; they are plain
literals now.
PiAuthOptions is now PiAuthenticationMode, and auth accepts an environment
record. Pass the gateway key that way instead of writing it into the
process-wide environment while a session is created. Derive the thinking
level from the adapter's settings, which adds 'max'.
* build: hold vue-tsc at 3.3.11
vue-tsc 3.3.12 no longer sees a v-slot binding inside a component that
also has an event listener, so check:vue reports "Cannot find name
'control'" in MCPConnectionEditor and ProfileEditor. 3.3.11 checks them
cleanly.
* fix(ai): keep retryability for provider errors reported mid-stream
From ai 7.0.80 a provider error after the response stream starts is a StreamProviderError rather than an APICallError, so classifyAIChatError lost its isRetryable.
* feat(desktop): accept updates only when signed for their version
Tauri CLI 2.12 records the app version in each updater signature, and
updater 2.13 checks it against the version latest.json announces. With
requireSignedVersion it also rejects signatures that carry no version, so a
tampered manifest cannot pair a newer version number with an older, still
validly signed bundle.
Release assembly now fails when a signature does not name the version
being released, instead of shipping one that installed apps would reject.
* docs: note the dependency update's security fixes in the changelog
* feat(ai): recommend the latest models
The provider packages now know Claude Sonnet 5.5 and Opus 5.5 and the GPT-6
series. Make Sonnet 5.5 and GPT-6.1 Sol the defaults, list Opus 5.5, Fable
5.1, GPT-6 Astra and GPT-6 Luna, and replace the two free OpenRouter models
that OpenRouter no longer serves.
* build: align the fig package's valibot with the workspace
* 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(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(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.
* 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.
* feat(cli): export components as Storybook stories
Add `openpencil export -f storybook`, which writes one CSF3 `.stories.ts`
file per component set or component. Each variant becomes a story and the
variant properties become select controls, so the story renders the matching
variant; an unknown combination throws instead of showing another variant.
Stories embed the existing inline-style HTML projection, so consumers need no
OpenPencil runtime. `--framework react|vue|html` only changes the render
wrapper and the Meta/StoryObj import. When the document sits under the current
directory, stories carry an `openpencil://` design link for
@storybook/addon-designs.
Refs #727
* fix(pen): size auto-width text from its content on import
Text without a width in an auto-layout parent was imported 10000px wide, a placeholder the app's text measurer replaces. Headless layout keeps stored sizes, so CLI HTML and Storybook exports stretched hugging frames to over 10000px. Import the width as 0 so the importer's existing text-length estimate applies, and headless layout estimates the rest.
* feat(app): follow layer links to other pages
openpencil:// and web ?node= links only searched the current page, so a Storybook story linking to a component on another page reported it missing. When the current page has no match, load the other pages without showing them and switch to the first that carries the name.
* feat(cli): add design images and watch mode to Storybook export
Each story now links to its own variant when the layer name is unique, and carries a 2x PNG of the variant for @storybook/addon-designs, imported so Vite bundles it. --watch re-exports on every save. Re-exports replace the stories a previous export of the same document generated, including those of deleted components, and refuse to overwrite hand-written stories or another document's.
Refs #727
* fix(cli): reference Storybook design images without ambient PNG types
Import design images with new URL(..., import.meta.url) instead of an import declaration, so consumers need no vite/client types to typecheck the stories. Document that exports should run from the same directory.
* fix(app): search other pages for a link without cancelling page switches
The cross-page layer search prepared each page with preparePage, which advances the page-switch generation, so a page switch the user had in progress could be dropped, and every searched page paid for fonts and layout. Add loadPageNodes, which populates a page's layers through the same worker path without touching the switch generation, and report a failed search as an error instead of a missing layer.
* fix(pen): never import width-less text zero wide
Text without a width now imports at width 0 and relies on the importer's text-length estimate, which skipped single-glyph text. Estimate zero-width text of any length.
* fix(cli): harden Storybook export ownership, titles, and links
- A --page export replaces only its own stories, and names files as a full export does, so it cannot delete or overwrite other pages' stories.
- Same-named components on a page get distinct titles, so Storybook story ids do not collide.
- Read the generated header through CRLF line endings, and refuse a source containing a line break, which would end the header comment and start code.
- Link a story only to a layer name no other layer carries.
- Document the --page default for Storybook export.
Refs #727
* fix(app): let a page switch overtake a link's layer search
A link search that loads other pages could resume after the user started switching pages and move them to the matching page. Expose pageSwitchCount, which advances whenever a page switch starts, and abandon the search when it changes. An overtaken search reports neither a match nor a missing layer.
* fix(pen): estimate only omitted text widths
Estimate a width-less text node's width when it is imported, instead of estimating every zero-width text node afterwards, so an explicit width of 0 is kept.
* fix(cli): track Storybook story ownership by document path and page
- Identify the document by its path relative to the output directory rather than a basename or cwd-relative path, so same-named documents do not share stories and the export no longer depends on the working directory.
- Record the page in each story's header; a --page export replaces all of that page's stories and asks for a full export when renumbered file names land on another page's.
- Check every target, including design images, before removing anything, and refuse to overwrite files this export does not own.
- Quote the header fields as JSON with U+2028/U+2029 escaped, so any path stays inside the comment, instead of refusing line breaks.
- Deduplicate titles by Storybook id, which ignores case and punctuation.
Refs #727
* fix(app): focus a searched page only after its switch committed
A page switch the user starts while the link search's own switch is pending can keep that switch from committing. Check that the search's switch was the only one and landed on its page before focusing; otherwise report the search as superseded.
* fix(pen): keep empty text without a width at zero
* fix(cli): remove only the design images a Storybook export generated
Replacing a story removed its whole .design folder, including files someone else put there. Read the images each owned story references, remove just those, and remove a .design folder only once it is empty.
Refs #727
* test(app): cover a page switch still pending during a link search
The previous test committed the overtaking switch, so the page check alone caught it. Advance the switch count without committing, so the test fails without the count check.
* fix(cli): stage Storybook exports and refuse linked design folders
- Write every file to a staging folder inside the output before removing the previous export, then move them into place, so a failed write no longer leaves the export half replaced.
- Refuse a .design path that is not a real folder, such as a symbolic link, before removing or writing images through it, so an export cannot reach outside the output directory.
Refs #727
* refactor(dom-css): print Storybook stories from a parsed template
Story modules were assembled from string fragments, so quoting and
layout were an implicit contract: the CLI found design images with a
regex that only matched double-quoted `new URL("…")` paths.
A story module is now one TypeScript template, parsed once with acorn
and its TypeScript plugin. Data is filled into `$placeholder` nodes and
the module is printed with esrap, which owns quoting and escaping. The
CLI reads referenced design images back through `storyImagePaths()`
instead of matching text. Tests import generated modules and assert
values rather than formatting.
* refactor(storybook): track generated files in a manifest
The export recovered which files it owned by parsing its own output: a
header regex over JSON-quoted strings, line-separator escaping, CRLF
handling, an AST walk for design images, and a path regex in the CLI.
A `.openpencil-stories.json` manifest now records the document and page
behind each generated file. The CLI validates it with Valibot, including
that every listed path stays inside the output folder, and the story
header is a plain note. Story ids use a copy of Storybook's `sanitize`,
tested against the installed Storybook; the previous rule treated `A§B`
and `A-B` as the same story. Export names use es-toolkit's `pascalCase`.
The CLI export command moves into `commands/export/`, dom-css splits
grouping and naming out of the Storybook exporter, and the CLI takes the
framework list from dom-css.
* fix(pen): keep explicit narrow text widths
A post-import pass widened every multi-character text narrower than two
font sizes, including widths the `.pen` file set on purpose, such as
`width: 0`. Omitted widths are now estimated when the text node is
created, so the pass only overrode explicit widths and is removed.

* refactor!: move shared primitives below dom-css and core
dom-css depended on core for color conversion, base64 helpers, text
direction, and web-font assets, so core could not use dom-css and every
caller special-cased HTML and Tailwind output.
Color conversion and management, base64 helpers, and text/layout
direction now live in scene-graph under `color`, `bytes`, and
`text-direction`. dom-css takes web-font resolution as an injected
`fonts` option and owns the font face types, so it depends only on
scene-graph and core can depend on it.
BREAKING CHANGE: `@open-pencil/core/color` and `@open-pencil/core/bytes`
are removed, and the direction helpers are no longer exported from
`@open-pencil/core/text`; import them from `@open-pencil/scene-graph`
subpaths. `exportHTMLBundle` takes a font resolver in `fonts` instead of
`'assets'`.
* fix(tools): import color parsing from scene-graph in visual bisect
* fix(mcp): declare the scene-graph dependency
MCP imports `@open-pencil/scene-graph/bytes` since base64 helpers moved
there, but only reached scene-graph through core, so isolated installs
and package checks depended on transitive resolution.
* refactor!: use js-base64 directly instead of a base64 wrapper
Base64 helpers had moved into scene-graph only to sit below dom-css,
but they are a thin wrapper over js-base64 and unrelated to the graph;
fig already called js-base64 directly.
Callers use js-base64 and check `isValid` where input comes from outside
(clipboard, imported HTML, tool arguments, the plugin API). A new
`open-pencil/no-hand-rolled-base64` lint rule rejects atob, btoa, and
Buffer Base64 conversions, and AGENTS.md records the convention.
BREAKING CHANGE: `@open-pencil/core/bytes` is removed; use `js-base64`.
* fix(dom-css): keep images with invalid Base64 inline in HTML export
`exportHTMLBundle` accepts documents parsed from outside HTML, and
js-base64 drops characters it cannot decode, so extracting an invalid
image data URL wrote different bytes. Such images now stay inline.
* fix(packages): make packed exports runtime-safe
Make checked-in package manifests truthful for ordinary npm and Bun packing, and verify installed artifacts under both runtimes. Centralize package discovery, artifact inspection, and bounded process execution so CI and release publication share the same contracts.
* ci: build package dependencies before checks
Keep workspace jobs independent of ignored dist output now that public package exports consistently resolve built artifacts.
* ci: preserve source-first engine tests
Keep the broader dependency build for package and repository validation, but retain Core-only setup for engine shards so workspace tests continue exercising source modules.
* ci: build engine shard dependencies
Build the seven workspace packages imported by engine tests in dependency order. This preserves a single module instance per package and keeps each clean CI shard independent of ignored dist output.
* ci: restore established package build boundaries
Keep the original repository and engine job setup, and add installed artifact verification only after the existing package build. Avoid changing which module copies unrelated tests execute.
* fix(packages): preserve Bun source identity in tarballs
Retain source-first workspace resolution and ship complete source trees for Bun conditions. Verify clean installed consumers without overlaying archives, reuse consumer validation before release publication, and repair Bun 1.3.10 private source alias resolution.
* refactor(tooling): reuse package and process utilities
Use pkg-types for manifest I/O and types, tinyexec for subprocess lifecycle, and npm's pack listing for release staging. Preserve archive verification and project release invariants rather than reimplementing package-manager file selection.
* refactor(tooling): resolve workspace roots at CLI boundaries
Discover and validate the nearest workspace once, support explicit roots, and pass roots to reusable checks. Replace subprocess entrypoint dispatch with direct calls and preserve aggregate package diagnostics without adding arbitrary test timeout increases.
* fix(release): enforce publication boundaries
Use root version alignment and shared validated npm output parsing. Enforce the public npm registry policy and test verification-before-publication, mismatched artifacts, and partial retries without registry writes.
* refactor(tooling): validate package responses with Valibot
Express npm pack and manifest identity contracts as schemas, infer parsed output types, and preserve contextual failures and relative-path safety. Document Valibot as the first-party validation convention while retaining Zod at SDK boundaries.
* refactor(tooling): validate manifests at input boundaries
Share Valibot schemas for consumed manifest fields, recursive exports, supported workspace declarations, and npm registry responses. Infer domain types and reject malformed metadata instead of silently skipping it downstream.
* refactor(tooling): group package helpers by ownership
Colocate manifest and workspace contracts, separate npm response parsing from generic JSON handling, and split smoke packing, installation, and runtime checks. Remove the release tarball forwarding shim and consolidate its coverage in package-artifacts. Preserve public tooling exports and CLI commands.
* refactor(canvas): adopt immutable CanvasKit paths
- Upgrade CanvasKit to 0.41.1 across app, Core, CLI, and Vue peers
- Build mutable geometry with PathBuilder and detach immutable paths for drawing
- Replace in-place strokes, transforms, and boolean operations with immutable results
- Update renderer mocks and path construction tests for the new API
* test(canvas): model immutable path ownership
- Return detached path instances from CanvasKit builder mocks
- Assert shadow ring and combined path disposal
- Preserve recorded vector operations across ownership transfer
* fix(build): align CanvasKit workspace versions
- Prefer private Unix sockets with TCP fallback for local MCP clients
- Unify HTTP and WebSocket lifecycle, authentication, and cleanup
- Discover transport details from an owner-only runtime file
29 tools: open_file, save_file, new_document + all 26 from @open-pencil/core.
Stdio for MCP clients (Claude Code, Cursor), HTTP (Hono + Streamable HTTP
with sessions) for scripts, browser extensions, CI.
Runs on both Bun and Node.js (via tsx).
