* 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
* fix: use official Homebrew cask installation guidance
* docs: guide localized pages through the old Homebrew tap
The translated getting-started pages documented the official cask but not
the migration from the archived tap, so readers of those pages had no
uninstall step for the old formula.
Document current public contracts and implemented workflows, correct invalid editor and slot examples, and distinguish supported font, recovery, and library behavior from remaining gaps.
