* 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.
* feat: check designs live with a Check panel and canvas issue markers
Design lint only ran from the CLI and AI tools, and its rules were too noisy
to show continuously: on a real imported page 786 of 888 layers had a
warning. The rules now report where a finding is actionable (a hardcoded
color only when a variable matches it, nesting only where the limit is
crossed, instance sublayers through their main component) and carry
structured data, and Recommended keeps warnings for likely problems.
The app checks the current page after edits settle. The Check tab groups
issues by rule with hover highlighting, reveal on click, and one-step
variable binding. Errors and warnings are marked on the canvas with
clustered markers that roll up to visible ancestors when zoomed out; markers
explain themselves on hover, open Check on click, and toggle with
View > Design issues.
* fix: keep the right panel and markers stable
The Check tab made the right-panel tab row overflow at common window widths,
so focusing the zoom menu scrolled the row and shifted the panel. Code and
AI tabs now drop their labels to screen readers when the row is narrow.
Touch target names are matched as whole words: "Rectangle" contained "cta"
and marked every rectangle. Markers also stay drawn during interactive edits
instead of blinking while a value is scrubbed.
* fix(ui): show right panel tab labels whenever they fit
* fix(ui): name the design check tab Lint and keep panel tabs consistent
The tab was an unlabelled icon between labelled Code and AI tabs. It is now
Lint, with the same icon and label anatomy as its neighbours, and its icon
takes the severity color instead of a count badge. All labelled tabs show
their labels when the row fits and drop them together when it does not.
* refactor(ui): build the Lint panel from shared components
Issue groups use AppCollapsible, actions use AppButton, and the severity
filters are a Reka toggle group with keyboard navigation. Issue rows no
longer nest a button inside a button. Panel state, visibility and the
focused-issue scroll live in useDesignCheckPanel, the rules menu is its own
component, and rule preferences change through preference actions.
Severity ordering reuses Core's ranking, detail numbers follow the app
language, and the check debounce uses useTimeoutFn.
* fix(lint): check the WCAG AA touch target size in the Recommended preset
Recommended flagged a 394 × 39 input because it required the 44 × 44 AAA size. It now checks the 24 × 24 AA minimum through a minSize option; Strict and Accessibility keep 44 × 44.
* feat(lint): fix design issues from rules, the Lint panel, the CLI, and agents
Rules attach fixes as data: a safe fix keeps the design as it looks (bind a
color to the variable it matches, round subpixel geometry that layout does
not own), a suggestion changes values (snap radius and spacing to the
scale, raise small text to the minimum). One Core applier re-validates
each fix against the current graph and merges changes per layer.
The Lint panel offers a fix per row and Fix all for safe fixes as one undo
step; openpencil lint --fix writes the fixed document; the lint and
lint_fix tools expose the same to MCP and AI chat.
The design-check spec's Close button is now 24 x 20: at 24 x 24 it passes
the WCAG AA touch target size that Recommended checks.
* feat(lint): pin issues outside the view to the canvas edge
Errors and warnings on layers outside the viewport had no marker, so a
check could report issues nobody could see. They are now pinned to the
canvas edge where a ray from the viewport center toward them leaves it,
with a chevron pointing their way; pins in one direction merge like
markers. Hovering lists them under the direction they lie in, and
clicking reveals and opens the most severe, nearest one.
Pins keep clear of UI floating over the canvas: the toolbar marks itself
with data-canvas-obstacle, and canvases report such rectangles to the
renderer through getOverlayObstacles each frame.
* feat(lint): mark layers with design issues in the Layers panel
Like an IDE marks files with problems and the folders holding them, a
layer with errors or warnings shows the most severe as an icon, and a
collapsed layer with issues inside it shows a dot in that color.
Suggestions stay in the Lint panel, as on the canvas, and the marks
follow the View → Design issues toggle.
* feat(lint): show issues per page and across the document
Loaded pages beyond the current one are now checked in the background,
one page at a time while the editor is idle, and checked again only when
an edit touches them; pages a large .fig file has not loaded are left
alone until opened rather than forced in. The page list shows each page's
errors and warnings like an IDE's problem count, and the Lint panel gains
a Document scope that lists every page's issues, tags the ones on other
pages, and switches to a row's page when it is opened.
* test(lint): use the core-tests alias and no comma operator in lint tests
Master now rejects ../../ imports and the comma operator in tests.
* refactor(app): create the Lint session with the editor store modules
The composition root passed its line budget once master added recent
pages; the Lint session belongs with the other per-editor services that
the modules factory creates and disposes.
* docs(changelog): keep master's latest Unreleased entries
* 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.
* fix(text): request script fallbacks for substituted text
When a text's font could not be loaded and the default family
substituted for it, font readiness returned before checking glyph
coverage. That check is what requests CJK and Arabic fallbacks, so text
such as Chinese in an unavailable PingFang SC drew missing glyphs unless
another layer happened to request the fallback first.
Substituted text now observes glyph coverage too. It waits while a
fallback loads and stays visible when none is available.
* fix(fonts): explain installed fonts with unsupported outlines
On macOS 15 and later PingFang ships only `hvgl` outlines, which neither
font-kit nor CanvasKit can read. The desktop loader spent over a second
parsing the collection per style, and the font banner showed PingFang as
substituted with no explanation.
The loader now reads the family's table directories first and returns a
structured unsupported-format error. The font manager records it per
face, document font status exposes it as `reason`, and the banner shows
it inline with the full explanation in a tooltip. The resolver reports
progress after each failed candidate so the banner updates before web
font lookups finish.
* fix(fonts): keep the unsupported-format reason after failed retries
A later host attempt that returns no font no longer clears the reason; only a loaded face does.
* feat(settings): configure tool access and agent step limits
Built-in AI exposed only a hardcoded subset of the tool registry, and the
maximum agent steps was a constant, so users could neither enable
extended tools such as create_component nor adjust long-running tasks.
Built-in AI and the local MCP server now keep independent, locally saved
tool permissions over one shared catalog, with searchable read-only and
side-effect groups and per-target defaults. Chat settings gain a validated
maximum-steps field whose captured value drives the stop condition,
remaining-step warnings, and limit detection for each message.
Tool access, the local server, browser access, and MCP connections are
grouped under a single Automation settings page.
Closes#573Closes#584
* refactor(settings): split automation into MCP and Tool access pages
The Automation page mixed a permission matrix with server endpoints behind
a Tools/Connections switch, and the view switch was indistinguishable from
the provider switch. The nested scroll region showed three of 110 tools.
Rename the MCP-facing page to MCP and give tool permissions their own Tool
access page. The page owns a fixed toolbar for the target, count, defaults,
and search, so the list uses the full dialog body and no row is clipped.
* fix(automation): explain MCP startup failures with localized guidance
Every startup failure collapsed into "MCP server did not become healthy":
the spawn layer recorded the real error but the runtime discarded it, and
health probes could not distinguish a rejected token from a missing server.
The message also surfaced raw English text as the alert heading.
Classify failures by reason (not installed, denied command, early exit,
startup timeout, rejected token, unexpected response, unreachable) and
render translated heading and guidance from the catalog, keeping captured
stderr or HTTP status as labeled diagnostic detail.
* refactor(ui): share one collapsible disclosure primitive
Six features each wired Reka's collapsible with their own motion classes and
one settings-only theme token, so the same interaction drifted in spacing,
icon size, and reduced-motion handling.
Add AppCollapsible with a family theme and move the settings disclosure and
the model editor's advanced settings onto it. Chat and frame-preset call
sites keep their distinct visuals for a follow-up.
* fix(automation): explain MCP failures with localized details
The failure alert carried raw English error text as its heading, and the
diagnostic payload sat in a sibling block outside the alert with no
relationship to it.
Classify failures by reason, render translated heading and guidance from
the catalog, and keep the payload in a collapsible inside the alert, which
unmounts while collapsed so the live region announces only the summary.
Add a copy action for issue reports.
Find the executable where a graphical launch can: extend PATH with the
common global bin directories before the lookup and report the searched
directories as diagnostic detail.
* fix(automation): keep MCP failure details out of reasons already explained
An unreachable address and a rejected token already name their cause in the
translated guidance, so repeating it under Details added noise. Details now
carry only output the summary cannot: stderr, HTTP status, or an unknown
error message.
* test(settings): browse every MCP failure reason in Storybook
The failure copy lived inside the settings panel, so reviewing the eight
reasons meant reproducing each failure and the mapping could only be
checked through the panel's dependencies.
Extract MCPFailureAlert, which owns the reason-to-copy mapping, detail
visibility, copy action, and restart action, and add a story covering
every reason plus the collapsed-details behavior.
* fix(ui): order alert details above the recovery actions
The alert rendered its action buttons before the details slot, so the
collapsible explanation of a failure appeared under the controls it
explains. Details now render directly after the description.
* fix(automation): correct MCP failure classification and detail
Review follow-ups on the failure diagnostics.
Only 401 and 403 mean the server refused our token; any other status now
reports an unexpected response instead of telling the user to replace a
token that was never the problem.
The install hint rendered the whole diagnostic detail as its package
argument, so searched directories appeared inside the install command.
The install target is now a domain constant and the searched directories
stay as detail, which not-installed failures surface again since they are
the actionable desktop diagnostic.
Exited failures also record the process exit code and signal so copied
diagnostics stay conclusive when stderr is empty. The bundled PATH test
now covers the append branch instead of only the unchanged path.
* feat(settings): accept custom values for presets and retention
Retention was a closed set of three counts while the AI step limit was a
free number, so two bounded numeric preferences looked and behaved
differently for no product reason.
Add a shared preset-or-custom field: presets stay one click, the escape
hatch reveals a validated numeric field, and the model carries only the
resolved number. Diagnostics retention becomes a bounded number (50 to
20,000) with the presets as shortcuts, and the hardcoded revalidation in
the panel is replaced by one domain resolver.
* fix(settings): label the preset and custom fields
Replacing the labeled provider field with the shared control left the AI
step limit as a bare select with a detached hint paragraph, outside the
settings group, so nothing on screen said what the number meant. The
accessibility name came from aria-label, which is why behavior tests
passed while the panel was unreadable.
Move both controls into labeled settings rows with their descriptions, and
give the revealed field its own accessible name so the two controls in one
row differ. The specs now assert the control lives inside the row that
names it, which is the check that would have caught this.
* fix(mcp): allow the desktop app origin by default
A server started manually bound the port and answered curl but the app
webview could not use it: no CORS origin was configured, so the browser
blocked every fetch and the app reported the server as unhealthy. The
workaround required an undocumented environment variable.
Allow the desktop app origins by default, accept a comma-separated
override, and document the default in the CLI help and the security notes.
Authenticated requests still need the bearer token, and browsers set Origin
themselves, so only the app webview can present these origins.
* fix(settings): address review findings on the new controls
Copy details awaited nothing and confirmed the copy before the write
finished. VueUse never rejects and falls back to a legacy write, so the
await is what makes the confirmation honest rather than an error branch.
The preset field only left custom mode when a preset arrived; a non-preset
value assigned from the owner left the select showing a value absent from
its options with the field still hidden. The watcher now follows the model
in both directions.
The story play functions queried the revealed field by the row label, which
Testing Library matches as a whole string, so those interactions could not
find it. The Storybook smoke assertion also assumed a button or tab, which
skipped every story built from other primitives.
Share typed MCP, AI, and WebMCP exclusions across adapters. Preserve the browser tool inventory through explicit exclusions and keep execution support and user permissions independent.
Define native Valibot inputs and execution/exposure metadata on each tool. Derive effects and default capabilities, consume upstream Standard Schema conversion, and validate finite numeric inputs consistently across adapters.
Move atomic execution to Core and restore failures from Scene Graph checkpoints without relying on a property diff. Preserve topology, collections, indexes and surviving object identities during rollback.
BREAKING CHANGE: custom tools use input schemas and execution metadata instead of params, ParamDef and independently declared mutation flags. Direct tool execution validates inputs before invoking the handler.
Register inspection and atomic editing tools through document.modelContext with input validation, result bounds, captured targets, cancellation guards, and workspace cleanup. Verify native browser discovery and cross-page undo.
