* feat(MCP): follow agent activity in canvas
* fix(fig): preserve imported design fidelity
Keep component overrides, variable-backed icon colors, page backgrounds, and fixed text sizing intact across lazy FIG materialization.
* feat: add selection-context MCP tools and mode
* chore: scope work branch to MCP selection and canvas follow
* fix: honor MCP-only tool contracts in CI
* refactor(mcp): drop the follow and selection-context tools this branch carried
Following agents landed in #725, through the agents registry and the
chat's follow toggle, so this branch's MCP follow setting and its
follow-agent module are superseded. The see_user_selection and
get_user_selection_details tools duplicated get_selection, get_node,
describe, get_page_tree, and export_image; the selection-only workflow
they served is rebuilt on those tools in the following commits.

* feat(mcp): make get_selection the compact entry point with a depth
get_selection returned every selected layer's whole subtree, which is
too much as the first call when the user points at a large frame. It now
returns the selection with direct children by default, counts deeper
children as childCount, and takes a depth.

* feat(mcp): share only the selection with MCP clients
A selection scope, set with Share only the selection in the local
server settings or OPENPENCIL_MCP_SCOPE=selection, limits MCP clients
to get_selection, get_node, get_page_tree, describe, and export_image
on the selected layers and what they hold.
The server enforces the scope on everything it sends to the app: MCP
sessions and /rpc, which stdio clients also go through, carry only
those tool calls and the session-closed notice, each stamped with the
scope, so a client cannot reach other tools or the settings that would
widen it. The app's bridge rejects node IDs outside the selection,
points describe and export_image at the selection when they name no
nodes, and asks get_page_tree for a root inside it. A stdio client can
ask for the scope itself while the server shares the whole document.

* fix(mcp): keep selection-scoped clients from writing files or listing wider tools
export_image writes its result to a file when given a path and an MCP
root is set, which reaches past reading the selection. A path is now
refused in selection scope, by the tool registration before the call
and by the app's bridge, so a client with a stale scope cannot write
either; the image itself is still returned.
A stdio client follows the narrower of its own scope and the scope the
server records, instead of letting OPENPENCIL_MCP_SCOPE=document list
tools a selection-scoped server rejects.

* test(mcp): name the selection scope's tools instead of reading the allowlist
The server test compared the listed tools with SELECTION_SCOPE_TOOLS,
the same list that decides registration, so a tool added to it by
mistake would still pass. It now names the five tools the scope offers.

* 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.
* 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
* refactor(design-jsx): extract design JSX into its own package
Design JSX elements, helpers, schema, reference, and JSX export only need
the scene graph, yet lived in Core, so every consumer of the authoring API
pulled in the renderer, layout, and file formats.
@open-pencil/design-jsx now owns them and depends only on scene-graph. The
renderer takes icon lookup, SVG conversion, vector creation, and layout as
DesignJSXServices; Core binds its own and exports the bound renderJSX and
renderTree from @open-pencil/core/design-jsx.
* feat(design-jsx): export the JSX runtime for TSX authoring
The package already had a JSX runtime, but nothing exported it, so design
trees could only be written as function calls or JSX strings. Export
`./jsx-runtime` and `./jsx-dev-runtime` so `jsxImportSource` works, and make
`Fragment` produce the same empty-type node as `<>` in `renderJSX` strings.
* fix(design-jsx): render fragments nested in other elements
A fragment builds a node with an empty type, which only renderJSX expanded, and only at the root. Nested fragments and fragments passed to renderTree failed with 'Unknown element: <>'. Inline fragment children when trees are built, and share root expansion between renderTree and renderJSX.
* 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.
Share canonical tool inputs with AI and browser adapters through Valibot and Standard Schema while retaining MCP numeric coercion and existing transports.
BREAKING CHANGE: programmatic integrations use SDK v2 server/client types; paramToZod is removed in favor of the shared Core tool input contract.
* 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.

Fixes#194
Remove headless SceneGraph mode — the MCP server now always proxies
tool calls to the browser via WebSocket. One server, one architecture:
HTTP :7600 — /health, /rpc (CLI), /mcp (MCP Streamable HTTP)
WS :7601 — browser connects, executes tool calls against live editor

- Delete headless SceneGraph, open_file, save_file, new_document
- Delete canvaskit-wasm dependency (no headless rendering)
- Add ws dependency for WebSocket server
- Rewrite tests with mock browser over real HTTP+WebSocket

13 tests using InMemoryTransport from @modelcontextprotocol/sdk:
- Tool registration (all 76 tools listed with descriptions)
- new_document, open_file, save_file lifecycle
- Tool execution through MCP protocol (create, fill, delete, query)
- Error paths: no document loaded, nonexistent node, invalid file path
- Full workflow: new → create → nest → query → delete
Fix @open-pencil/core dep in MCP package: workspace:* for local dev
