Fixes#134
TEXT nodes created via SceneGraph.createNode() defaulted to empty
fills, causing text to be invisible when .fig files are opened in
Figma. Now defaults to a solid black fill matching Figma's behavior.
Closes#133
Strip optical size suffixes (e.g. "DM Sans 9pt" → "DM Sans") and
"Variable" suffixes when writing fontName.family to .fig files.
This ensures Figma recognizes the font instead of showing a
"Missing font" dialog.
Closes#131
Each RPC tool call created a fresh FigmaAPI instance, so switch_page
set currentPageId on a throwaway object. Sync the page change back
to the editor store after tool execution.
Fixes#112
* fix(set_layout): default to HUG sizing when enabling auto-layout
When `set_layout` transitions a frame from `layoutMode: 'NONE'` to
auto-layout, it now sets `primaryAxisSizingMode` and
`counterAxisSizingMode` to `'AUTO'` (which maps to HUG internally).
Previously these remained at `'FIXED'`, causing the frame to keep its
original dimensions instead of shrinking/growing to fit children. This
made `h="hug"`, `justify="end"`, and `grow={1}` appear broken when
containers were created via the `set_layout` MCP tool (as opposed to
the JSX `render` path, which already defaulted to HUG).
The fix only applies when `direction` is provided and the frame was
previously in `layoutMode: 'NONE'` — updating spacing or alignment on
an existing auto-layout frame does not reset sizing modes.
* docs: add changelog entry for set_layout HUG sizing fix
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 http.ts (merged into server.ts)
- 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
- Simplify bridge.ts to 6 lines (just imports and starts the server)
* Fix text rendering: always use paragraph wrapping, font fallback, batch tools, severity levels
Rendering:
- renderText: always use paragraph when fontProvider available, not just
when node-specific font loaded — fixes single-line overflow for Georgia/
non-Inter fonts
- buildParagraph: add Inter as fallback fontFamily so paragraph wraps text
even when requested font not yet loaded
- measureTextNode/buildTextPicture: remove isNodeFontLoaded gate — measure
with fallback font for consistent layout↔rendering
- TEXT_PICTURE_KEYS: add width/height so textPicture invalidates on resize
- renderText drawText fallback: clip to node bounds
- onAfterExecute: invalidate textPictures after font load
Layout:
- estimateTextSize: accept maxWidth, compute multi-line height
- toJSON: depth parameter with childCount fallback
AI tools:
- batch_update tool: multiple set_layout/set_layout_child in one call
- describe: accept ids array for multi-node inspection
- Issue severity (error/warning/info) with pattern classification
- checkNestedFlexWithoutFill: cross-axis fill tolerance
- CORE_TOOLS trimmed 34→27, rest moved to EXTENDED
- System prompt: batch_update, describe ids, severity rules, font/text
wrapping guidance, card grid patterns
* Add Pexels stock photo integration for AI chat
- stock_photo tool: search Pexels by query, download image, apply as
IMAGE fill on any node. Picks resolution based on node dimensions.
- Pexels API key stored in localStorage, synced to core via
setPexelsApiKey on change
- ProviderSettings UI: Pexels API key input with link to get free key
- System prompt: stock photo usage guidance
- Added to CORE_TOOLS so AI can use it in every session
* Batch stock_photo + calc, 4-phase workflow, fix wrap false positives
- stock_photo: accepts JSON array of requests, all fetched in parallel.
Rejects nodes with children (leaf shapes only). One call replaces 14.
- calc: accepts JSON array of expressions or single string. One call
replaces 3 separate calc invocations.
- System prompt: 4-phase workflow (plan → skeleton → content → polish).
Batch stock_photo and calc examples. Updated step budget.
- describe-layout-issues: skip 'nested flex may collapse' for wrap
containers (pill/tag frames are intentionally HUG). Extract
childNeedsFill helper to reduce complexity.
* Fix nested flex false positive for pills, single-root render rule
- describe-layout-issues: skip 'nested flex may collapse' when a sibling
already has grow or fill — pill/badge frames next to flex-grow content
are intentionally small (e.g. BreakingLabel next to ticker text)
- System prompt: render must have exactly one root element. Stock_photo
401 fallback: tell user, don't eval gradients.
* Rework workflow: render complete sections, not empty frames
Phase 2 now prescribes 5-7 renders, each producing a complete section
(nav, hero, stories, opinions, sidebar, footer) with placeholder images,
real text, proper auto-layout. No more empty frames to fill later.
Removes the fill content phase — skeleton IS the content, just without
real photos. Phase 3 is now just polish (batch stock_photo + fixes).
Step budget: 12-15 steps instead of 15-30.
* Pexels key input: match AI key behavior
Same pattern as the AI provider key — intermediate ref, 'Key saved —
enter new to replace' placeholder, Clear button, save on change. No
longer exposes the raw key in the input field.
* No empty frames in skeleton, select nodes after each tool
- System prompt: explicit rules against empty frames, no pre-creating
wrapper frames for future content. Each render = complete section with
visible placeholders. Render 1 = only nav+ticker, not the whole page
with empty containers.
- tools.ts: set selection to flash node IDs after each mutating tool,
so user sees which section AI is working on (selection border persists
vs flash which is transient).
* AI overlay: pulsing blue while working, green flash on done; skeleton workflow
Rendering:
- ai-overlays.ts: new module with pulsing blue border (sinusoidal
opacity 0.3-0.8 at 1.5s period) for nodes AI is working on, green
fade-out flash (800ms) when done
- renderer.ts: aiMarkActive/aiMarkDone/aiClearAll methods, drawn after
regular flashes
- constants.ts: AI_ACTIVE_COLOR, AI_DONE_COLOR, timing constants
Integration:
- ai-adapter.ts: onBeforeExecute now receives args (for target ID)
- tools.ts: marks target node (id or parent_id) active before tool
executes, marks done via onFlashNodes after completion
- editor.ts: aiMarkActive/aiMarkDone/aiClearAll forwarded to renderer
Workflow:
- System prompt: 3-phase skeleton workflow. Phase 2 renders gray
placeholder blocks (Rectangle bg=#E2E8F0) for every section — page
looks like wireframe before any real content. Phase 3 replaces
skeletons with real content. Phase 4 batch stock_photo + polish.
* render replace_id: atomic skeleton-to-content swap, fix AI overlay lifecycle
render tool:
- New replace_id parameter — renders new content, places it at the
skeleton's position in parent, then deletes the skeleton. No visual
gap between skeleton removal and content appearance.
AI overlay fixes:
- Track lastActiveIds across before/after execute — aiMarkDone clears
the exact nodes that were marked active, not just the result IDs
- aiFlashDone: direct green flash on result nodes (not gated by
_aiActiveNodes membership)
- replace_id included in target ID detection for active marking
System prompt:
- Phase 3 uses render({ replace_id }) instead of delete_node + render
* Fix gradient fills, nested flex false positives, render insert_index, h=hug prompt
- set_fill: gradient support with color_end + direction (top-bottom,
left-right, etc). Uses proper Matrix type. No more eval for gradients.
- describe-layout-issues: skip nested flex warning for all non-MIN
alignments (SPACE_BETWEEN, CENTER, MAX) — not just SPACE_BETWEEN
- render: insert_index parameter for controlling child order
- system prompt: page frame h="hug" not fixed height
- AI overlay: mark active on any tool with target ID (not just
mutating), clear previous active in onBeforeExecute
* Add desktop business news site example to system prompt
Full workflow example: skeleton with gray placeholders → replace_id
content fills → batch stock_photo. Shows 12-col grid pattern, card
components, section headers, sidebar widgets, h=hug page frame.
Complements the existing mobile app UI example.
* Drop blue active pulse, keep only green done flash
Blue active marking was invisible — tool execution is 20-80ms (one
frame), AI thinking happens between tool calls where no hooks fire.
Green done flash on result nodes works and is visible.
* Blue pulse on skeleton during AI tool streaming
Watch streaming message parts in ChatPanel — when a tool part appears
with state 'call'/'partial-call' and has replace_id or parent_id in
args, mark that node active (blue pulse). When tool transitions to
'output-available', mark done (green flash). This shows the pulsing
blue border on the skeleton wireframe frame while AI generates JSX,
and switches to green when the content replaces it.
* AI overlay debug log section, watch tool parts by toolCallId
- chat-debug.ts: aiOverlayLog array + AI OVERLAY LOG section in debug
output showing every part/mark-active/mark-done event with timestamps
- ChatPanel.vue: check parts by toolCallId instead of isToolUIPart,
log all overlay events to aiOverlayLog for debugging
* Fix AI overlay: use 'input' not 'args' for tool part params
Vercel AI SDK UIToolInvocation uses 'input' field (not 'args') for
tool call parameters. The watch was checking p.args which was always
undefined, so no overlay events ever fired. Also use p.type instead
of p.toolName for the log.
* Move AI overlay to onBeforeExecute/onFlashNodes, reorder render params
- onBeforeExecute: mark replace_id/parent_id active (blue pulse)
- onFlashNodes: clear active, flash done on new nodes (green)
- Reorder render tool params: replace_id first so streaming partial
input reveals target ID before JSX body
- Remove ChatPanel watch — all overlay logic in tools.ts now
- Add aiClearActive() to renderer (clears active without touching
done flashes)
* Wait 2 rAF frames after marking active before tool execute
onBeforeExecute marks the target node active (blue pulse), but
execute ran immediately after without yielding to the render loop.
The blue frame was never painted because markActive → execute →
clearActive all happened in the same JS task. Now await two
requestAnimationFrame callbacks so the canvas renders at least one
blue-pulse frame before execution starts.
* Add comprehensive AI overlay debug logging to chat debug log
Both streaming watch (ChatPanel) and tool execution hooks (tools.ts)
now log every event to aiOverlayLog with full state: renderer exists,
activeNodes count, hasFlashes, node existence. This will show exactly
what happens and why the blue pulse is or isn't visible.
* Filter partial node IDs in streaming overlay watch
During input-streaming, replace_id may be partially received (e.g.
'0:' without the number part). Guard with isValidNodeId check.
Also refactor watch callback into collectPendingTargets +
syncOverlayState to stay under complexity limit.
Analysis of last debug log:
- Hero: only 235ms active (streaming didn't deliver replace_id early)
- Stories: 14.8s active — should be clearly visible
- Opinions: 12.5s, LatestNews: 11.5s, Stocks: 9.8s — all long enough
- Hero was the only one too fast to notice
* Fix undo race, JSX pragma conflict, partial ID overlay, add deletion log
- Fix undo snapshot race condition: replace shared `let beforeSnapshot`
with a per-tool stack. Vercel AI SDK runs tool calls from one step via
Promise.all — concurrent mutating tools overwrote the shared snapshot,
causing wrong undo entries and potential content loss.
- Fix 'h is not a function' JSX error: rename sucrase pragma from `h`
to `__h`. When AI writes `.map((h, i) => ...)`, the loop variable
shadowed the pragma, crashing render.
- Fix partial node ID `0:1` in overlay: strengthen `isValidNodeId` to
require both parts ≥2 chars and verify node exists in graph. During
streaming, `replace_id: "0:1811"` arrives as `0:1` → `0:18` → etc.
- Add deletion log to SceneGraph: `_deletionLog` records id, name,
type, parentId, timestamp, and truncated stack for last 200 deletions.
Included in debug log as NODE DELETION LOG section to diagnose the
intermittent frame disappearance bug.
* Reduce find_nodes spam and describe bloat in system prompt
- Instruct AI to reuse IDs from render results and describe output
instead of calling find_nodes to rediscover them (saves 8+ calls)
- Recommend depth=1 for full-page describe, depth=2 only for sections
* Auto-depth describe + validate-after-render workflow
Describe tool now auto-picks depth based on subtree size when depth
is omitted: ≤15 nodes → depth 4, ≤40 → 3, ≤100 → 2, larger → 1.
Max raised to 5 for explicit overrides.
Prompt updated: after each render replace_id, call describe on that
block (auto depth gives full detail on small sections). Every 2-3
content renders, describe root at depth=1 to catch cross-section
layout issues early.
* Enforce describe-after-every-render in system prompt
Show explicit render → describe → fix pattern with code example.
AI was skipping per-block validation and batching all describes
at the end, causing compounding layout errors.
* Add describe rules: nested text, missing padding, button padding, row centering
Four new layout issue detectors in describe-issues.ts:
- Nested Text (error): Text node inside Text causes overflow.
Suggestion: split into separate Text elements in flex row.
- Zero padding container (warning): Frame with fill + text children
but no padding — content touches edges.
- Button without padding (warning): Button-like frame with children
but zero horizontal padding.
- Row without vertical centering (warning): Horizontal flex with
items=start, tall container, and short children — suggests
items=center.
All verified with bun -e tests including false positive checks.
* Fix gradient alpha loss, add undersize child detection
Gradient fix: set_fill with color_end was overwriting alpha to 1
on both gradient stops (`{ ...c, a: 1 }`). Now preserves original
alpha from parsed hex — #00000000 → a:0, #000000AA → a:0.667.
This caused transparent-to-dark overlays to render as solid black.
New describe rule: detect child significantly narrower than parent
in a container without auto-layout (e.g. 100px Rectangle inside
896px Frame). Suggests adding flex + w=fill. Caught the HeroImg
bug that describe previously missed.
* Auto-include issues in render result, no separate describe needed
Render tool now scans the created subtree for errors/warnings and
includes them in the response. AI gets issues automatically without
needing to call describe — eliminates the pattern where AI skips
describe on 'simple' sidebar blocks.
Example response:
{ id: '0:42', name: 'Card', issues: [
{ node: 'Text', id: '0:45', message: 'no color', severity: 'error' }
] }
* Run layout before collecting render issues
Issues were checked on raw node sizes (default 100px) before
computeAllLayouts ran in onAfterExecute. Now render calls
computeAllLayouts inline before collectSubtreeIssues, so issues
reflect actual computed dimensions.
This fixes hundreds of false 'X 100px overflows parent' warnings
that made AI chase nonexistent problems.
* Revert auto-issues in render and layout-before-issues
Reverts 09a9b89 and 70c116a. Auto-including issues in render
result caused false positives (100px default sizes before layout)
and made AI chase nonexistent problems, degrading output quality.
* Clean up AI chat PR: remove debug scaffolding, add stock photo provider adapter
- Delete _deletionLog (stack traces on every node deletion)
- Delete aiOverlayLog and all debug push() calls
- Delete succesful_prompt_diffucult_ux.md (raw debug dump) and tokens.md (empty)
- Remove double-rAF hack from ai-adapter (added 32ms to every tool call)
- Restore simple beforeSnapshot for undo (was matching by tool name)
- Remove 70-line overlay state tracker from ChatPanel.vue
- Remove Math.* regex hack from calc (expr-eval has builtins)
- Refactor stock-photo into provider adapter: Pexels + Unsplash
- Add Unsplash key management to settings UI and use-chat composable

* feat(mcp): add export_image_file tool — saves PNG/JPG/WEBP to disk
The existing export_image tool returns base64 inline, which MCP clients
display in chat but don't save to disk. This new tool writes the image
directly to a file path, making exports usable for documentation,
mockup reviews, and CI pipelines.
Parameters:
- path: absolute file path to save (required)
- ids: node IDs to export (optional, defaults to all top-level nodes)
- format: PNG | JPG | WEBP (default: PNG)
- scale: 0.1–4 (default: 2)

* feat(mcp): add export_image_file tool and fix headless PNG rendering
**New tool: `export_image_file`**
Saves rendered PNG/JPG/WEBP images directly to a file path on disk.
The existing `export_image` returns base64 inline — useful for chat
but doesn't produce files. AI agents and CI pipelines need actual files.
Path validation runs before the expensive render call. The tool
respects `fileRoot` restrictions.
**Fix: headless PNG rendering now matches the editor**
1. `computeAllLayouts()` called after `render` creates nodes via JSX.
2. Bundled Inter font loaded from disk — tries `../fonts/` (installed
package) then `../../public/` (project root). The web-based
`fetch('/Inter-Regular.ttf')` fails in Node.js.
3. Text measurement uses `renderer.measureTextNode()` — the same
ParagraphBuilder the renderer uses to draw text. Measurement and
rendering use the same SkiaRenderer instance, same fontProvider,
same font shaping. Zero hacks.
Export pipeline:
ensureInterFont() → SkiaRenderer + loadFonts() →
setTextMeasurer(renderer.measureTextNode) →
computeAllLayouts() → renderNodesToImage()
**Tests added** (6 new tests in mcp-server.test.ts):
- export_image_file produces valid PNG after render
- export_image_file without ids exports all page children
- export_image_file without document returns error
- export_image_file with out-of-root path returns error
- JPG and WEBP formats produce non-empty output
- export_image_file is listed in tools
* Remove .cue directory and revert .gitignore changes
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Move computeAllLayouts into renderTree, reuse exportImage in MCP
computeAllLayouts was in the render tool but renderJSX has multiple
callers (render, replace_node, automation server). Moving it into
renderTree ensures layout is always computed after JSX rendering.
export_image_file in MCP server was duplicating export_image logic.
Now delegates to exportImage.execute and just handles the file write.

When a frame/instance has no visible fills, Figma renders drop shadows
using the first child's shape instead of the node's own rectangle.
This makes shadows follow rounded children (e.g. pill-shaped badges
inside a rectangular wrapper).
Pass the first visible child as shadowShapeChild to renderEffects
when the container has no visible fills.
Figma's kiwi format uses FOREGROUND_BLUR for what the Plugin API calls
LAYER_BLUR — a blur that applies to the entire layer including children.
Previously FOREGROUND_BLUR was handled in the per-effect 'front' pass via
applyClippedBlur, which only blurred the node's own fills (drawn before
children). For nodes with no fills but with children (like groups),
the blur had no visible effect.
Now FOREGROUND_BLUR is handled alongside LAYER_BLUR in renderNode,
using a saveLayer that wraps both the node content and its children.
This fixes gradient blobs that should appear soft/blurred (e.g. the
decorative gradients in gold-preview.fig's Preview Thumbnail).
Frames with resizeToFit=true are Figma's internal representation of
Groups. They auto-resize to fit children and never clip content,
regardless of the frameMaskDisabled flag.
Previously all frames with frameMaskDisabled=false were imported with
clipsContent=true, causing group-like frames to incorrectly clip their
children. This was visible as hard edges on gradient fills that should
extend beyond the group bounds.
Instance swap overrides (symbolOverrides with overriddenSymbolID) now
correctly propagate through multi-level clone chains:
- Track swapped instances in a dedicated set to distinguish real swaps
from normal clone-chain componentId differences
- Reclone children when a source instance was swapped, copying name,
componentId, and re-populating children from the swapped component
- Mark recloned targets as swapped too, enabling transitive propagation
to deeper clone levels (e.g. Preview Thumbnail toolbar icons)
- Only rename on swap when the current name matches the root component
name, preserving user-given names like 'Static Icon'
- Use getComponentRoot (with cycle detection) instead of manual chain walk
- Null-check source before deleting target children in recloneChildren
- Replace calc.ts (150 lines) with expr-eval library
- Replace rgbLuminance with culori wcagLuminance
- Use @iconify/utils iconToSVG for viewBox normalization in iconify.ts
- Extract describe-shared.ts: findAncestorBackground, looksLikeButton, CONTAINER_TYPES
- Extract icon-render.ts: shared createIconFromPaths for create.ts and renderer.ts
- Inline codegen prompt as TS constant, remove runtime fs.readFile from MCP server
- Fix blur effect color alpha (a:1 → a:0)
- Encapsulate module-level mutable state in src/ai/tools.ts into RunState class
- Add network check to iconify tests (skip gracefully offline)
- Remove Caddyfile.dev and components.d.ts from tracking, add to .gitignore
The fill color bug was caused by a missing `ref` import in FillPicker.vue,
introduced in 37da83a and fixed in 3b32b4d. Add a regression test that
opens the color picker, clicks the color area, and verifies the node's
fill color updates.
Variable/collection IDs (e.g. 'VariableCollectionID:42:1') parsed via
stringToGuid produced NaN sessionID, which Kiwi encodes as 0 — same
GUID as the DOCUMENT node. This overwrote DOCUMENT in changeMap during
re-import, causing all pages to be lost.
Fix: generate unique GUIDs for collections, variables, and modes via
localIdCounter instead of parsing string IDs. Pass varIdToGuid map
through to serializeVariableBindings for consistent references.
Test has never passed since it was added (3b32b4d). Add console.log
to show page counts, node counts, and internal-only flags so the CI
log reveals what the export→parse roundtrip actually produces.
Engine:
- layoutSizingVertical/Horizontal setters now use child's own layout
direction (not parent's) to map primary/counter axis — matches Yoga
- FILL on cross-axis uses alignSelf:Stretch instead of flexGrow
(flexGrow only works on main axis, caused even distribution bug)
- FILL on main axis auto-sets layoutGrow=1 for leaf nodes
This fixes the 20-step debugging spiral where AI set FIXED heights
on HORIZONTAL children inside VERTICAL parent but Yoga ignored them
(wrote primaryAxisSizing via parent axis, Yoga read counterAxisSizing
via child axis — never saw the FIXED value).
Describe noise reduction:
- Suppress 'absolutely positioned inside flex' — intentional for
decorative overlays (selection handles, badges)
- Suppress 'justify=between with HUG' when node fills parent width
- Suppress 'fixed size + grow' when sizing is FILL (standard pattern)
- 'Inconsistent padding' requires 3+ siblings (not 2)
Prompt:
- Bail-out: delete and re-render after 2 failed set_* attempts
- eval restricted to operations, not layout debugging
- Track per-run step count, warn AI when 5 steps remain via _warning
field injected into tool results
- Show 'Continue' button in chat when step limit (50) is exhausted
- Add step budget section to system prompt so AI plans ahead
- Reset run step counter on each new agent call via prepareCall
configureTextLeaf for HEIGHT mode was calling yogaChild.setWidth(child.width)
unconditionally, which locked text at the 100px default. This blocked
Yoga's alignSelf:stretch from expanding text to the parent's cross axis.
Now skips setWidth when text has layoutAlignSelf=STRETCH in a vertical
parent (w="fill" case). Same fix for the headless fallback path.
Test: text with w="fill" in flex="col" stretches to 260px (300 - 2×20 pad).
export-jsx: Text with layoutAlignSelf=STRETCH (w="fill" in col parent) or
layoutGrow>0 (w="fill" in row parent) was emitting w={computedPx} instead
of letting the fill/grow detection below handle it. Now skips fixed w
emission when text stretches or grows.
describe: wrap layout without rowGap flagged — wrapped rows stick together.
prompt: wrap always needs rowGap.
Tests: 2 new round-trip tests for text w="fill" in col and row parents.
Two fixes:
1. layout.ts: Add estimateTextSize() fallback (~0.6 × fontSize per char)
for when MeasureFunc returns null (font not loaded) or CanvasKit is
unavailable. Previously fell back to child.width/child.height which
defaults to 100×100 for new nodes, blowing up every HUG container.
2. ai/tools.ts: Only call computeAllLayouts + requestRender + push undo
for mutating tools (def.mutates). Read-only tools (describe, get_jsx,
node_bounds, etc.) were triggering full layout recompute on every call,
wasting cycles and potentially destabilizing layouts during AI sessions.
- Load all font weights including default family (Inter 500/600/700 were skipped)
- Fix weightToStyle mapping: 400 → Regular, not Medium
- Block render loop during file loading to prevent stale fallback renders
- Prefer Figma textPicture when available over buildParagraph
- Clear textPicture when text properties change
- Await font loading before first render on file open and page switch
OpenPencil format: zero property differences, compressed under 1MB.
Figma format: node count, clipsContent, constraints, arcData,
layoutAlignSelf all verified against the fixture file.
* Perf: cache label collection, offload .fig compression to worker
Label cache: collect sections/components once per scene change,
filter by viewport on each frame. Eliminates full tree walk during
pan/zoom (~17ms/frame → <1ms on large files).
Export worker: move fflate compression off the main thread to prevent
frame drops during save (451ms+ → non-blocking).
* Perf: worker-based .fig parsing, instance index, non-blocking font loading
- Offload .fig parsing (unzip + Kiwi decode) to a Web Worker
- Add instance index (componentId → Set<nodeId>) for O(1) getInstances()
- Defer graph event subscription during file open to skip redundant syncs
- Make font loading non-blocking — render immediately, load fonts in background
- Copy image buffers before worker transfer to prevent detached ArrayBuffer crash
- Show toast on font load failure and file open errors
- Cache failed Google Fonts families to avoid repeated network requests
- Fix missing ref import in FillPicker
- Yield to UI between parse and layout for responsive loading spinner
* Image drag-and-drop and clipboard paste onto canvas
* Paste images at cursor position, track canvas cursor in state
* Paste nodes at cursor position (Figma and internal clipboard)
* Fix review: center images at cursor, fix hasImageFiles, clean up hash/undo
* Paste at viewport center when cursor is outside canvas
* Fix Figma paste positioning: center nodes at cursor after import
* Image support: clipboard, export, drag-and-drop, paste, renderer, tools, UI
- Clipboard: embed image bytes (base64) in OpenPencil clipboard payload so
copy/paste between documents preserves image fills
- Fig export: write images/ folder to .fig zip (both fflate and Tauri paths)
- Tauri: extend build_fig_file to accept image entries
- Renderer: implement CROP (with imageTransform) and TILE (TileMode.Repeat)
scale modes, fix FIT to center the fitted image
- FigmaAPI: add createImage(bytes) with sync FNV-1a hash
- Tools: add set_image_fill tool for AI/MCP
- FillPicker: replace placeholder with file picker, preview, scale mode selector
- Drag-and-drop: new use-image-drop composable creates image nodes from dropped files
- Paste: keyboard paste handler detects image clipboard items
- Shared utils: extract hashImageBytes and getImageDimensions to src/utils/image.ts
* Add image tests and Yjs image sync for collaboration
Tests (18 new):
- FigmaAPI.createImage: deterministic hash, storage, format
- set_image_fill tool: all scale modes, error handling, storage
- Clipboard roundtrip: image bytes preserved, multiple images, children
- Fig export/import: zip contains images/, full round-trip
Collab:
- Add yimages Y.Map to sync graph.images via Yjs
- Observer applies remote image adds/deletes to local graph
- syncNodeToYjs pushes referenced image data alongside node props
- syncAllNodesToYjs bulk-syncs all images on room share
* Fix FillPicker: remove deleted utils/image import, use SHA-1 inline
* Extract storeImage() on editor store, use in FillPicker and placeImageNode
* Unify image hash: use sync FNV-1a everywhere, export computeImageHash
Editor store's hashBytes (async SHA-1) produced different hashes than
FigmaAPI.createImage (sync FNV-1a) for the same bytes. This meant
drag-and-drop images couldn't be deduplicated against AI tool images.
Replace hashBytes with computeImageHash from core. storeImage() is
now sync.
* Skip drawing IMAGE fills when image data is missing
When pasting from Figma, image fills reference a CDN hash but no pixel
data is included in the clipboard. Previously this rendered as a solid
black rectangle because applyImageFill bailed without setting a shader,
leaving stale paint state.
applyFill now returns false when the fill can't be applied, and callers
skip the draw call. The node still exists with the correct imageHash —
if the image data is later provided (e.g. via file re-open), it will
render correctly.
* Warn when Figma paste has missing image data
Show amber warning toast when pasted nodes reference image fills
without available bytes (Figma clipboard limitation).
Add 'warning' toast variant with tailwind-variants, extract toast
styles to src/components/ui/toast.ts.
* Use useFileDialog and useObjectUrl in FillPicker
Replace manual file input ref, click(), createObjectURL/revokeObjectURL
with vueuse composables. Remove hidden <input type=file> from template.

Text nodes with textAutoResize=WIDTH_AND_HEIGHT kept their 100×100
default SceneNode size when MeasureFunc was unavailable (no CanvasKit),
blowing up every HUG container.
Add fallback estimator (~0.6 × fontSize per char) in layout.ts so
headless layout produces sane sizes.
DO NOT change textAutoResize defaults in renderer.ts without testing
headless layout — see comments there and in layout.ts.
* Fix CJK text garbled when font unavailable (#69)
Always use buildParagraph for text rendering when fonts are loaded,
even when the node's specific font isn't available. The paragraph
shaper falls back to the CJK font in fontFamilies, instead of the
previous drawText fallback which used Inter (no CJK glyphs).
* Add renderText unit tests for CJK font fallback behavior
* Add CJK visual regression test with Noto Sans SC fixture
- Download NotoSansSC-Regular.ttf as LFS-tracked test fixture
- Add setCJKFallbackFamily() export for headless/test use
- Visual test verifies CJK text renders through buildParagraph fallback
when node font is unavailable (the exact PR #89 scenario)
- Assert dark pixel count > 500 to distinguish real glyphs from tofu
* Fix auto-layout overflow: MeasureFunc, min/max, absolute positioning, text wrap
Layout engine (layout.ts):
- Use Yoga MeasureFunc for text nodes instead of static pre-measurement,
so text wraps correctly when width is determined by flex layout
- Add min/max width/height constraint support (minWidth, maxWidth, etc.)
- Translate counterAxisAlignContent to Yoga setAlignContent for wrap layouts
- Extract configureFlexContainer to share between root and nested frames
JSX renderer (render/renderer.ts):
- Auto-set layoutPositioning ABSOLUTE for elements with x/y inside auto-layout
- Fix text auto-resize: set HEIGHT when text fills parent in auto-layout
Text measurer (renderer/renderer.ts):
- Accept optional maxWidth parameter for constraint-based measurement
* AI prompt: prefer describe over export_image for post-render verification
* Strip TS casts from AI-generated JSX before sucrase parse
AI models sometimes emit `as any`, `as const` etc. in JSX props.
Sucrase with jsx-only transform can't handle these, causing parse errors.
- Strip TypeScript cast expressions before passing to sucrase
- Add forbidden patterns to AI prompt: as any, template literals for
sizes, Math.random()
* Cache text MeasureFunc results to avoid repeated buildParagraph calls
Yoga calls MeasureFunc multiple times per node during calculateLayout.
Each call was creating a full CanvasKit Paragraph — expensive for layouts
with many text nodes. Cache by rounded constraint width.
* AI chat: fix provider settings popover, add max output tokens, fix paste in chat input
- Fix ProviderSettings popover not visible (remove tooltip/popover trigger
conflict, add collision-padding, isolate z-[51])
- Add configurable max output tokens (default 16384) in provider settings
- Pass maxOutputTokens to ToolLoopAgent to prevent truncated tool calls
- Add system prompt size limits: split render calls at ~40 elements
- Fix paste/copy/cut in chat input (stop event propagation to canvas handler)
* Fix 6 layout engine bugs: hidden size, FILL basis, SPACE_EVENLY, alignSelf range, grid stretch, absolute children
Layout engine (layout.ts):
- Guard applyYogaLayout to preserve hidden children dimensions
- Add setFlexBasis(0) for FILL sizing so children share space from zero
- Add SPACE_EVENLY to mapJustify via Justify.SpaceEvenly
- Replace hardcoded STRETCH checks with mapAlignSelf for full range
- Use setWidthStretch/setHeightStretch for grid children instead of flexGrow
- Insert absolute children in Yoga tree via configureAbsoluteChild with
PositionType.Absolute, keeping manual x/y (no write-back)
Types (scene-graph.ts):
- Add SPACE_EVENLY to LayoutAlign union
- New LayoutAlignSelf type: AUTO | MIN | CENTER | MAX | STRETCH | BASELINE
Import (kiwi-convert.ts):
- Map SPACE_EVENLY correctly instead of collapsing to SPACE_BETWEEN
- New mapAlignSelf function for full StackCounterAlign range
Tools (modify.ts):
- Expand set_layout align enum with SPACE_EVENLY
- Expand set_layout_child align_self enum with MIN/CENTER/MAX/BASELINE
Tests: 86 pass (+13 new covering all 6 fixes)
* Grid layout support in JSX renderer, auto-height grids, flex children stretch in cells
Renderer:
- Parse grid/columns/rows/columnGap/rowGap/gap props
- Parse grid child positioning: colStart/col/rowStart/row/colSpan/rowSpan
- Grid prop takes precedence over padding-triggered auto-layout
- SPACE_EVENLY added to ALIGN_MAP
- Numeric columns shorthand (columns={3} → 3×1fr)
- Auto-height: grid without rows sets height=0 for Yoga auto-sizing
- fill sizing in grid children → layoutAlignSelf: STRETCH
- Component builders accept variadic children: Frame(props, ...children)
Layout:
- Grid auto-height: skip setHeight when no gridTemplateRows
- Write back computed height for auto-height grids
- Grid children with layoutMode stretch width to fill cell
- recomputeGridChild: re-run flex layout after grid assigns cell size
(temporarily sets sizing to FIXED so HUG doesn't override grid width)
Export:
- Skip height export for auto-height grids (no rows template)
Tests: 18 new grid render tests covering all paths
* Auto-enable flex for justify/items props, discourage export_image in AI prompt
* Address review: use sucrase typescript transform, don't reset chat on maxOutputTokens change
* Fix lint errors: extract applyFrameSize, wrap nested ternary, remove unnecessary cast
* Remove SPACE_EVENLY — not a valid Figma layout value
* CI: debug LFS pull from R2
* Apply maxOutputTokens dynamically via prepareCall instead of at agent creation
* Fix heavy .fig parse: restore GUID/defID guards, fix optional types
Commit f3eac5a removed null guards from fig-import and
instance-overrides as 'unnecessary conditions', but Kiwi-decoded data
can have NodeChanges without GUIDs and ComponentPropAssignments/Refs
without defIDs. Made the types optional to match reality.
Also fix CI LFS: add git lfs install --force before pull (R2 endpoint
needs the filter registered first).
* Fix Google AI model IDs: gemini-3.1-pro → gemini-3.1-pro-preview
Closes#91

Co-authored-by: Danila Poyarkov <dev@dannote.net>
Deep-copy gradient and image transforms in copyFill to prevent
shared-reference mutations. Add mutation-isolation tests for all
copy helpers. Fix benchmark to use precomputed IDs and actual
copyFills function.
When pasting from Figma, instances may reference components that aren't
included in the clipboard data (e.g. components on a different page).
These instances stayed empty and invisible on canvas.
Convert them to FRAME so their own fills, strokes, corner radius, and
layout properties render visually.
Fixes#36
- Handle RAW lineHeight units (multiplier × fontSize) — was returning null
- Convert letterSpacing with percent units in style overrides — was using raw value
- Normalize variable font names (e.g. 'Inter Variable' → 'Inter') for Google Fonts and local font lookup
Fixes#36
Figma needs derivedTextData (layoutSize, fontMetaData with font digest)
and textUserLayoutVersion to render text in .fig files. Without these
fields, text nodes appear as empty boxes when opened in Figma.
- Add DerivedTextData message to kiwi schema (field 359)
- Add derivedTextData and textUserLayoutVersion to NodeChange codec
- Compute SHA-1 font digests from loaded font binaries at export time
- Emit textData.lines with lineType: PLAIN for each paragraph
- Expose getLoadedFontData() from fonts module for digest computation
Closes#64
Prevent reka-ui TreeItem from toggling expand/collapse on click —
expand is handled by the chevron button with @click.stop.
Match page rename input styling to layer tree: show file icon next
to the input, use the same compact border/padding classes.
* Add multi-provider AI support (Anthropic, OpenAI, Google AI, OpenAI-compatible)
- Add AI_PROVIDERS registry with per-provider model lists, key placeholders, and URLs
- Refactor use-chat composable: provider factory creates the right AI SDK model
- Per-provider API key storage in localStorage with automatic legacy migration
- New ProviderSetup.vue replaces APIKeySetup.vue with provider selector
- New ProviderSettings.vue popover accessible from gear icon in chat input
- OpenAI-compatible provider with custom base URL and model ID fields
- Install @ai-sdk/anthropic and @ai-sdk/google dependencies
- Update E2E tests for new provider setup flow
* Fix reactivity, key masking, missing model ID field, and chat reset on model change
- Use ref instead of computed for apiKey — computed getter over localStorage
wasn't triggering reactivity when the key was set
- Load stored key for new provider in providerId watcher
- Reset chat on modelId and customModelId change, not just provider switch
- Add custom model ID field to ProviderSetup.vue for OpenAI-compatible
- Simplify ProviderSettings key field — empty input with contextual placeholder
instead of fragile dot-masking that broke on partial edits
- Use data-test-id locator for model selector in E2E test
* Use useLocalStorage from vueuse instead of manual ref + watch + localStorage
Replaces 5 hand-rolled ref/watch/localStorage sync pairs with useLocalStorage.
API key uses a computed storage key that rebinds when the provider changes.
* Use useLocalStorage for collab name persistence
* Review fixes: changelog placement, remove dead class, cursor-pointer
* Extract ProviderSelect component and uiInput helper
- ProviderSelect.vue: shared select dropdown for AI providers
- ui/input.ts: shared input styling (sm/md sizes)
- Remove 7 duplicated input class strings across chat components
* Use uppercase acronyms: keyURL, customBaseURL, supportsCustomBaseURL
* Match select dropdown width to trigger via --reka-select-trigger-width
Move min-w-[var(--reka-select-trigger-width)] into selectContent base
style so all selects get it by default. Remove per-component overrides.
* Uppercase acronyms in variable names, improve setup form layout
- providerID, modelID, customModelID, setAPIKey, AIProviderID
- Keep apiKey lowercase at start (standard JS convention)
- Compact setup form: single column, full-width Connect button
- Fix grammar: 'a OpenRouter' → 'an OpenRouter'
- Shorter promo text
* Allow text selection in chat panel
* Fix chat E2E test: Save → Connect button text
* Disable mermaid in chat markdown renderer
Alias mermaid and beautiful-mermaid to empty shims in Vite config,
preventing vue-stream-markdown from attempting to load them.
* Interleave text and tool calls in chat messages
Render message parts in order instead of grouping all tool calls
first then all text. Use SDK's isToolUIPart/isTextUIPart/getToolName
instead of custom type guards. Fix error state: output-error, not error.
* Implement figma.viewport.scrollAndZoomIntoView()
Figma Plugin API method that centers the viewport on given nodes.
Reuses the same bounding box logic as the viewport_zoom_to_fit tool.
* Catch tool execution errors and return them to the AI
Instead of crashing with an unhandled exception, tool errors are
caught and returned as { error: message } so the AI can retry or
explain the failure. UI detects error outputs and shows them in red
with the error message when expanded.
* Replace esbuild with sucrase for JSX transform
Sucrase is a pure JS transform (201 KB / 46 KB gzip) that works in
both Node/Bun and the browser. Replaces esbuild (13 MB WASM) which
only worked in Node/Bun.
- buildComponent() and renderJSX() are now synchronous
- render tool works in browser AI chat (no more 'esbuild required')
- Handles full JS expressions (map, ternaries, Array.from, etc.)
* Update system prompt to prioritize render tool with JSX
Document available tags, props, layout, text, and sizing options.
Instruct the AI to use full JS expressions in JSX for complex layouts.
* Fix zoom shortcuts to match Figma
Cmd+0: Zoom to 100% (was incorrectly mapped to Zoom to fit)
Cmd+1: Zoom to fit
Cmd+2: Zoom to selection
Shift+1 / Shift+2: same as Cmd+1 / Cmd+2
Add zoomTo100() and zoomToSelection() to editor store.
Refactor zoomToFit() to use shared zoomToBounds() helper.
* Refactor keyboard shortcuts to useMagicKeys
Replace manual keydown handler with VueUse useMagicKeys + whenever
for declarative shortcut registration.
- mod() helper for cross-platform Meta/Control shortcuts
- plain() helper for modifier-free keys
- Proper modifier exclusion (⌘G vs ⌘⇧G no longer conflict)
- Add E2E tests: duplicate, zoom (⌘0/⌘1/⌘2/⇧1/⇧2), auto-layout (⇧A)
- All 26 keyboard shortcut tests pass
* Fix scrollAndZoomIntoView to actually zoom
Match Figma Plugin API behavior (equivalent to Shift-1): compute
zoom level that fits all nodes with padding, capped at 100%.
Previously only set center without adjusting zoom.
Add VARIABLE_SET node type, variable-related messages (VariableSetMode,
VariableSetID, VariableDataValues, VariableScope, VariableDataMap, etc.)
to the Kiwi schema.
Export: emit VARIABLE_SET and VARIABLE nodeChanges on an internal-only
canvas page, include variableConsumptionMap on nodes with boundVariables.
Import: rewrite variable import to use variableSetModes, variableSetID,
variableResolvedType, and variableDataValues (multi-mode COLOR/FLOAT/
BOOLEAN/STRING/ALIAS). Import variableConsumptionMap bindings.
Closes#65
* Switch to @open-pencil/yoga-layout with CSS Grid support
Use our fork (open-pencil/yoga, grid branch) which cherry-picks the
upstream CSS Grid PRs (#1893–#1898) onto current main. The JS bindings
are ported from the old embind approach to the new wasm_bridge.c API.
npm:@open-pencil/yoga-layout alias keeps all imports as 'yoga-layout'.
Also handle FinalizationRegistry change (upstream #1908) — node.free()
no longer exists, nodes are garbage collected automatically.
* Add CSS Grid layout mode
Scene graph:
- LayoutMode gains 'GRID' option alongside HORIZONTAL/VERTICAL
- GridTrack type (sizing: FIXED/FR/AUTO, value) for track definitions
- GridPosition type (column, row, columnSpan, rowSpan) for children
- New node props: gridTemplateColumns/Rows, gridColumnGap, gridRowGap,
gridPosition
Layout engine:
- buildGridTree() sets Display.Grid and maps GridTrack[] to Yoga's
setGridTemplateColumns/Rows API with FR/Points/Auto track types
- Grid children use gridPosition for column/row placement with span
- Flex layout path unchanged
Store:
- setLayoutMode('GRID') auto-creates NxM track grid based on child
count (sqrt heuristic), defaults to 1fr tracks
UI (LayoutSection.vue):
- Grid button (grid-2x2 icon) added to flow direction row
- Columns/Rows track editors: ScrubInput for value + AppSelect for
sizing mode (Fill fr / Fixed px / Auto), add/remove buttons
- Separate column gap and row gap ScrubInputs
- Wrap button hidden when grid is active
- Flex alignment grid hidden when grid is active
Kiwi serialization skips GRID mode for now (no .fig codec support).
* Add grid layout integration tests
12 new test scenarios covering:
- Basic 2x2 grid, fixed columns, mixed fr/fixed, unequal fr weights
- Column gap, row gap, both gaps combined
- Padding offsets
- Explicit gridPosition placement, column span, row span
- Absolute children skipped
- Hidden children collapsed
- Nested grid inside flex parent (computeAllLayouts)
Also fix: grid frames as children of flex parents now correctly use
Display.Grid via configureChildAsGrid() instead of falling through
to configureChildAsAutoLayout() which set FlexDirection.
* Deduplicate grid yoga configuration
Extract configureAsGrid() and createGridChildNode() shared by
buildGridTree (root-level grid) and configureChildAsGrid (grid
nested inside flex parent).
* Add grid layout to changelog
* Add grid support to JSX and Tailwind CSS export
OpenPencil format: grid → columns/rows/columnGap/rowGap props,
child colStart/rowStart/colSpan/rowSpan.
Tailwind format: grid grid-cols-N grid-rows-N gap-x-* gap-y-*,
mixed tracks use arbitrary values (grid-cols-[200px_1fr_auto]),
child col-start-*/row-start-*/col-span-*/row-span-*.
Both formats: padding emitted for grid frames (shared with flex),
flex-only props (justify/items/wrap/gap) scoped to isFlex.
* Remove duplicate gridTrackToTw, use shared formatTrack
Also drop unused GridTrackSizing import from LayoutSection.vue.
* Fix grid icon: use layout-grid instead of grid-2x2
unplugin-icons can't resolve icon names with digits after hyphens
(grid-2x2 → grid2x2 which doesn't exist).
* Polish layout UI and fix auto-layout behavior
- Replace text labels with compact icons: ↔/↕ for gap, ☐ for uniform padding, T/R/B/L for per-side padding
- Direction-aware gap icon: ↕ for vertical, ↔ for horizontal
- Pin +/− padding toggle button right of gap input
- Fix alignment grid axes for vertical layout (transpose primary/counter)
- Fix grid switch: set FIXED sizing, compute frame size from children
- Remove hardcoded white fill from Shift+A wrap
- Auto-detect horizontal vs vertical from selection bounds
* Add flex-to-grid switch integration test
Verify HUG frame expands and children are placed in 2x2 grid
when switching from vertical flex to grid layout.
* Update changelog for grid layout
48 new E2E tests across 9 spec files, 26 mutation unit tests,
store/canvas test helpers, data-test-id attributes.
Fixes: explicit error in canvasBounds(), remove any casts,
trim trailing blank line, condense changelog entries.
- layers-panel: navigate to /demo so demo layers exist
- app-menu zoom-to-fit: zoom in first so zoom-to-fit has something to change

WebGL/SwiftShader snapshot rendering across runs
- Update empty-canvas snapshot for current dark-mode canvas appearance
- Add colorToHex8 (hex with alpha via culori formatHex8)

- Add normalizeColor (partial Color → full Color with defaults)
- Add colorDistance (Euclidean RGB via culori differenceEuclidean)
- Replace colorToCSS body with culori formatRgb
- Change rgba255ToColor to positional args (r, g, b, a)
- Remove duplicate formatColor from svg-export.ts and export-jsx.ts
- Remove duplicate colorDistance from tools/analyze.ts
- Remove duplicate convertColor from kiwi/kiwi-convert.ts
- Replace hand-rolled hex+alpha in HsvColorArea.vue with colorToHex8

- Strip tools/schema.ts from 1831 to 65 lines (remove duplicate tool defs)
- Fix tools/index.ts to export ALL_TOOLS from registry instead of schema
- Fix renderJsx → renderJSX typo in tools/create.ts and structure.ts
- Add geometry.ts with shared rotation/coordinate math utilities
- Add isArrayMixed() helper to use-multi-props.ts, deduplicate FillSection/StrokeSection/EffectsSection
- Fix broken test imports: use @open-pencil/core instead of relative paths into packages/core/src/
- Merge duplicate import statements across all test files
- Export profiler internals and style-run helpers from core index.ts
- Add 6 new test files: color, undo, snap, vector, style-runs, text-editor (98 new tests)
- Update renderer-effects test for renderer/ directory split
* Add SVG export
Scene graph → SVG serializer with support for rectangles, ellipses,
lines, stars, polygons, vectors (fill/stroke geometry and vector
networks), text with style runs, gradients (linear, radial, angular),
image fills, effects (drop shadow, inner shadow, blur), opacity,
rotation, flips, blend modes, clip paths, and nested groups.
- packages/core: svg-node.ts (minimal XML builder), svg-export.ts
(serializer), ExportFormat now includes 'SVG', computeContentBounds
extracted for reuse
- packages/cli: export command accepts --format svg
- UI: SVG added to ExportSection format picker (scale hidden for SVG),
context menu 'Export as SVG' option
- 47 new tests covering SVGNode builder, geometry blob → path, vector
network → path, and full node export for all shape types
* Update changelog
* Add export_svg tool to ToolDefs
Available via MCP, AI chat, and CLI eval command.
* Replace standalone export items with Copy/Paste as submenu
Figma-style submenu: Copy as text, Copy as SVG, Copy as PNG (⇧⌘C),
Copy as JSX. Keeps Export as PNG (⇧⌘E) as a separate item.
* Remove standalone Export as PNG from context menu
* Update changelog
Fix renderer-effects test: check drawStrokeWithAlign call site instead of
drawNodeStroke helper definition (stroke align refactor moved the method).
Add a step to build.yml that resolves git authors to GitHub usernames via
the compare API and appends a Contributors section to release notes.
- Scope hover hit-test to current page (was searching all pages including
internal component page, causing ghost hover outlines)
- Frames/sections without visible fills or strokes are click-through
- Groups are always click-through (only children are hittable)
- Clipping parents reject hits outside their bounds
- Instances/components check children before falling back to fill check
- Switch test fixtures from material3.fig (55MB) / nuxtui.fig (82MB) to
gold-preview.fig (537KB) for fast dev runs, gate heavy fixtures behind
BUN_HEAVY_TESTS env var (enabled in CI)
Replace BFS (which skipped DSD-modified nodes in visited set, breaking
the chain for deeper clones) with iterative convergence loop. Track
dsdSizeSet separately from dsdModified so nodes with only position/
geometry changes inherit size from their source.
Fix transitive override propagation: re-clone from source (not component)
to preserve componentId chain for DSD. Add syncChildrenDeep for deep
property propagation (stroke colors on nested vectors).
Reduces vector overflow in gold-preview.fig from 25 to 0 (visible,
unclipped).
- Resolve symbolOverride guidPaths by overrideKey instead of guid
- Handle overriddenSymbolID for instance component swaps
- Propagate overrides transitively through the componentId clone chain
- Preserve internalOnly flag on canvas nodes during export
- Scope computeAllLayouts to current page for paste/undo/font-load
Profiler modules in packages/core/src/profiler/:
- FrameStats: rolling 120-frame buffer tracking FPS, CPU/GPU times, node counts
- GpuTimer: EXT_disjoint_timer_query_webgl2 wrapper for GPU-side timing
- DrawCallCounter: WebGL context proxy counting draw calls per frame
- PhaseTimer: Chrome DevTools Performance panel custom tracks via User Timing API
- HudRenderer: in-canvas overlay with stats text and frame time bar graph
- CaptureStack: per-node profiling with speedscope JSON export
- RenderProfiler: orchestrates all layers with zero cost when disabled
Integration:
- SkiaRenderer.render() instrumented with phase markers for scene, picture
recording/replay, section titles, component labels, selection, rulers, flush
- Node counting and viewport culling tracking in renderNode()
- WebGL2 context passed through for GPU timer and draw call counter
- Shift+P keyboard shortcut to toggle HUD overlay
- toggleProfiler() added to editor store
During .fig import, instance nodes have no children — Figma expects
them to be cloned from their component. The componentId references
used original Figma GUIDs that didn't match our generated node IDs.
Fix:
- Track original GUID → new node ID mapping during import
- Remap all instance componentId references after node creation
- Iteratively populate empty instances from their components
(multiple passes needed since cloning creates new instances)
- Extract font key collection from editor store into
collectFontKeys() in packages/core/src/fonts.ts
- 18 tests: styleToWeight, weightToStyle, markFontLoaded/isFontLoaded,
collectFontKeys (nested nodes, style runs, deduplication, default
font filtering, invalid IDs)
MCP test: find_nodes searches currentPage only — switch to
FOUNDATIONS page where Button components live.
eval-cli test: material3.fig first page has 1 TEXT node, not 3 —
assert >0 instead of ==3.
Tauri's loadFont registered fonts with the CanvasKit provider but
not in core's loadedFamilies cache, so isFontLoaded returned false
and measureTextNode returned null during layout recomputation.
Add markFontLoaded() to core and call it from Tauri font loader.
Add tests verifying text measurement integrates with auto-layout
centering.
Each instance in Figma's clipboard carries symbolData.symbolOverrides
with per-child property changes (text, fills, visibility). The override
targets a child via guidPath which matches the overrideKey field on the
component's child node.
After cloning component children into instances, overrides are resolved
through the overrideKey→figmaId→internalId→clonedChild chain and applied
to the instance's children.
FRAME nodes with VARIANT componentPropDefs are now promoted to
COMPONENT_SET on import (both .fig files and clipboard paste).
Clipboard paste now respects the Internal Only Canvas: components
on it are used to populate instance children but are not pasted
as visible nodes, matching Figma's behavior.
When pasting from Figma, INSTANCE nodes reference their component via
symbolData.symbolID but have no children in the clipboard. If the
component was also pasted, clone its children into the instance using
the componentId mapping (cloneChildrenWithMapping).
Extract shared kiwi→SceneNode conversion into kiwi-convert.ts, used by
both fig-import.ts (.fig file opening) and clipboard.ts (Figma paste).
The clipboard import was a simplified copy that diverged over time:
- Missing SYMBOL→COMPONENT type mapping (Figma's kiwi name for components)
- textAutoResize hardcoded to NONE instead of using clipboard value
- No gradient/image fill support, no effects, no style runs
- Missing flipX/flipY, constraints, text decorations, arc data, etc.
- Percent letter spacing not converted to pixels
Now both paths use nodeChangeToProps() with identical conversion logic.
* Replace saveLayer with MaskFilter for drop shadows
Drop shadows now draw directly with MaskFilter.MakeBlur instead of
saveLayer + ImageFilter. Eliminates per-shadow offscreen buffer
allocation, significantly improving render throughput for scenes
with many shadowed nodes.
Text shadows still use saveLayer (MaskFilter can't be applied to
text glyphs individually).
Benchmark: 50 shadow nodes render at 1.55ms/frame (scene change).
* Cache per-node SkPictures for effect rendering
Nodes with visible effects (shadows, blurs) are recorded into
individual SkPictures and replayed on subsequent scene redraws.
Only the modified node re-records; unchanged shadow nodes replay
from cache.
- MaskFilter.MakeBlur for drop shadows instead of saveLayer
- Reusable effectLayerPaint and cached ImageFilters/MaskFilters
- invalidateNodePicture() called on node update
- invalidateAllPictures() on font load; invalidateScenePicture()
preserves node cache for scene-only invalidation
- Shadow benchmark: 50 nodes at 1.47ms/frame (scene change)
* Update changelog with shadow rendering performance improvements
Eliminates per-frame WASM allocations for shadows and blurs:
- Reusable effectLayerPaint instead of new Paint() per effect
- ImageFilter cache keyed by params (drop shadow, blur, decal blur)
- Zero allocations during SkPicture recording for cached effects
* Fix shadow rendering, implement blur effects, add spread support
- Fix drop shadow rendering order: draw shadows before fills so they
appear behind opaque shapes instead of on top (#23.1)
- Implement shadow spread: expand/contract shadow shape by spread value
for both drop shadow and inner shadow (#23.2)
- Implement background blur: clip to node shape and apply blur filter
to content behind the node (#23.3)
- Fix text shadows: use saveLayer with ColorFilter.MakeBlend to apply
shadows to text glyphs instead of the bounding box (#23.4)
- Implement layer blur with actual saveLayer + blur filter instead of
the no-op comment (#23.3)
- Implement foreground blur: clip to node shape and blur content in
front (#23.7)
- Add inner shadow spread support with rounded rect handling
- Add makeRRectWithSpread and makeRRectWithOffset helpers
Closes#23
* Add Effects section to demo showcasing shadow and blur fixes
Drop shadows (subtle, medium, heavy, with spread), inner shadows
(inset, with spread, on ellipse, combined), text shadows on glyphs,
layer blur, and glassmorphism background blur card.
* Fix drop shadow, layer blur, and background blur rendering
Drop shadow: use MakeDropShadowOnly to produce shadow-only output
that doesn't bleed through opaque fills. The sigma is radius/2 to
match Figma's blur convention.
Layer blur: wrap entire node content in a saveLayer with blur filter
at the renderNode level instead of trying to blur after-the-fact
in renderEffects.
Background/foreground blur: extract clipNodeShape helper to reduce
duplication in blur effect rendering.
Update tests to match new rendering approach.
* Add visual regression tests for effects rendering
9 snapshot tests covering drop shadow, inner shadow, spread,
ellipse shapes, text glyphs, layer blur, and combined effects.
* Make Effects demo section background white
* Clean up renderer code and tests
- Extract applyClippedBlur to deduplicate background/foreground blur
- Remove comments that repeat what code does
- Format with oxfmt
* Add undo/redo support for effect property changes
ScrubInput controls (offset, radius, spread, opacity) now use
scrubEffect for live preview and commitEffect on release to create
a single undo entry per interaction.
Covers a few gaps in the existing MCP test suite:
- find_nodes filtering by type (wasn't exercised at all)
- create_shape with an invalid type enum (Zod enforcement)
- create_shape with a missing required param (Zod enforcement)
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
(pnpm publish resolves this to the actual version at publish time).
- Use Int32Array instead of Uint32Array for Kiwi pasteID (signed int field)
- Error toasts: don't auto-dismiss, show copy button, text is selectable
- Add clipboard roundtrip tests (encode → decode → verify)
Redo was creating duplicate childIds because snapshots captured after
tree construction had populated childIds, and createNode appends to
parent.childIds again. Fix: clear childIds in redo snapshots.
New tests (7):
- layoutAlignSelf from stackChildAlignSelf
- clipsContent from frameMaskDisabled
- fontWeight from fontName.style via styleToWeight
- letterSpacing object → pixels conversion
- undo removes full subtree
- redo recreates correct parent-child tree
- redo without childIds:[] demonstrates the duplicate bug
Figma clipboard data includes VARIABLE_SET, VARIABLE, and other non-visual
types that were falling through to the default RECTANGLE case in mapNodeType.
These now join DOCUMENT and CANVAS in the skipTypes set.
The first render records an SkPicture before fonts are loaded (fallback
drawText path). When fonts finish loading asynchronously, the cached
picture was never invalidated — subsequent renders replayed stale picture
without paragraph text. Hovering a node forced a full re-render (volatile
overlay path), making text reappear. Un-hovering replayed the stale cache.
Fix: call invalidateScenePicture() at the end of loadFonts() so the next
render records a fresh picture with proper paragraph text.
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).
9 app-menu tests: menu visibility, all 6 submenus content, Undo/Duplicate/
Zoom to fit via menu actions.
2 autosave tests: write triggers after scene change with mock file handle,
no write without file handle.
- Replace _id/_graph/_api with Symbol-keyed properties so eval scripts
can't access SceneGraph internals directly
- fills/strokes/effects return frozen structuredClone copies
- Fix currentPage getter to define selection only once per proxy
- Fix layoutSizingHorizontal/Vertical: respect parent layout direction
even when the node itself is an auto-layout frame
- Add 6 new tests: layoutSizing, frozen arrays, internals not exposed
- sceneNodeToJsx() in @open-pencil/core: converts SceneNode subtree to JSX
- CodePanel.vue with Prism.js highlighting, line numbers, copy button
- Third tab in properties panel: Design | Code | AI
- 14 new tests covering shapes, text, layout, effects, multi-selection
Tool part type is 'tool-create_shape' (name embedded in type field),
not a separate toolName property. Extract via part.type.replace('tool-', '').
Mock transport now emits proper UI message stream protocol:
tool-input-start → tool-input-delta → tool-input-available → tool-output-available.
Use markRaw to prevent Vue from deep-proxying the Chat class
instance, which broke its internal Vue refs. Add dedent for
multiline prompts.
Tests use mock transport by default. Set TEST_REAL_LLM=1 and
OPENROUTER_API_KEY to run against real OpenRouter.
Editing a main component now propagates to all instances:
- Instance children are mapped to component children via componentId
- syncInstances() copies properties from component to instances,
skipping any property marked in the overrides record
- New children added to a component appear in existing instances
- Store calls syncIfInsideComponent after updateNode, commitMove,
commitResize — changes propagate automatically
- Demo creates real instances (Button, Badge) in the App Preview
Tests added: instance creation with child mapping, sync propagation,
override preservation, new child addition, detach.
- 'Design System' section containing Desktop and Mobile frames
- Desktop: header, hero card, avatar, two content cards
- Mobile: status bar, banner, list items, FAB button
- Color palette swatches (Primary, Success, Warning, Danger, Purple)
- Updated E2E tests for new demo structure
- Reverted section title pill to always use fill color (not blue)
- Fix axis mapping for nested frames with different layout directions
(e.g. vertical child inside horizontal parent had swapped sizing)
- Fix stretch alignment not applying to leaf children when set on parent
- Fix layoutGrow being ignored on children with FIXED primaryAxisSizing
- Add 42 unit tests covering all layout scenarios
Document structure: Document (root) → Pages (CANVAS) → Nodes.
Each page has its own viewport (pan/zoom) and background color.
- CANVAS node type for pages
- SceneGraph: addPage(), getPages(), getAbsolutePosition stops at CANVAS
- Store: currentPageId, switchPage(), addPage(), deletePage(), renamePage()
- All operations (create, select, paste, hit test, render) scoped to current page
- Per-page viewport state saved/restored on page switch
- Pages list in LayersPanel with add/switch/double-click rename
- .fig import creates proper pages from DOCUMENT→CANVAS hierarchy
- Renderer takes pageId to render correct page's children
- Unit test for pages, updated E2E tests for page-scoped graph
- Force TreeRoot re-mount via :key when tree structure changes,
fixing Reka UI not reacting to items prop updates
- Only reparent into frames on mouseup when user actually dragged,
preventing click-to-select from moving nodes into overlapping frames
- Expose store on window for test introspection
- 6 new E2E tests for layers panel
Horizontal and vertical rulers rendered directly in CanvasKit:
- Dark background, tick marks at adaptive intervals
- Coordinate labels scale with zoom level
- Blue highlight showing selected node extent on each axis
- Corner square at ruler intersection
- Fork kiwi-schema from source TypeScript (evanw/kiwi), drop npm dep + patch
- Deduplicate GUID/Color types into src/types.ts
- Extract UI colors and default fills into src/constants.ts
- Replace hand-rolled hex parsing with culori library
- Extract demo shapes from App.vue into src/demo.ts
- useUrlSearchParams from VueUse for test mode detection
- Move fig-file/fig-import into kiwi/ (format layer)
- Delete PoC files (poc-yoga.ts, poc-test.ts)
