The app and SDK ambient SFC declarations disagreed on indexed props. SDK-first declaration order reproduced all twelve Storybook default-argument errors. Use the same opaque fallback and compile existing stories under both declaration orders as a regression check.
Acquire section paragraphs once, reuse proven fitting layouts, and bound retained text with borrowed native-resource lifetimes. Share document text family selection and Arabic/CJK coverage resolution rather than preserving missing glyphs. Validate exact zoom parity with real existing font fixtures.
Document current public contracts and implemented workflows, correct invalid editor and slot examples, and distinguish supported font, recovery, and library behavior from remaining gaps.
Share indexed recency, count/weight budgets and native disposal across six caches while preserving domain invalidation and eviction policies. Keep pools, weak memos and dependency-owned resources separate.\n\nAccount for effect pixels incrementally and preserve caller ownership on rejection. Validate disposal, slot reuse, exact integer accounting and unchanged raster output.
Choose readable opposite edges for rotated frame titles and size badges, sharing placement with hit testing. Render section titles as compact inset badges with contrast-aware borders and hover feedback.
Reject replacement of captured node and variable objects, preserving references on rollback. Reuse traversal and comparison schemas and the node-not-found helper to remove the duplication failures without changing tool inputs.
Render selected labels from reactive options rather than cached menu text. Refine action-row hover and cursor states, add a connection-test icon, simplify media credentials, and share semantic external links across Settings. Cover locale switching and link destinations with focused regressions and Storybook states.
Use a slot-based section for consistent spacing and accessible headings. Align selectors, simplify translated copy, and separate experimental rendering and reload feedback. Keep section states in Storybook.
Backing installation advances the preview baseline but previously stamped old whole-scene pictures with the new scene version. Zooming outside backing coverage could replay deleted content and hide newly created shapes.
Discard mismatched pictures before advancing that baseline, preserving valid pictures. Cover scene, preview, page and font invalidation plus exact visible pixels through zoom reversals in retained and tiled renderers.
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.
Retain one selection-property subtree while frame presets are shown. Suspend opted-in descendant scopes after cleanup, cancel drafts before detachment can blur inputs, close portals, and release previews and pending resource work.
Track focused-element removal with VueUse so WebKit shortcuts resume after input teardown. Cover retained identity, hidden inactivity, binding rollback, async disposal, undo, popup reactivation and browser focus behavior.
Record property presence for exact undo/redo, including explicit undefined values, and reject instance index mutations. Tighten numeric and operand schemas to match execution contracts.
Keep successful glyph coverage weakly owned by source nodes rather than repeating shaping when dense scans evict native paragraphs. Preserve font/input invalidation and bound pending ID invalidations without increasing native cache limits.
Add a dense-preview regression with exact raster comparison and count paragraph builds across all canvas renderers. The previous compiled build rebuilds 3,600 paragraphs over three held frames; the fixed build rebuilds none.
Skia analytic coverage depends on framebuffer dimensions as well as raster origin. Replay existing retained subtree pictures into the live viewport at settlement, while preserving overscan images for navigation. Keep settlement pending until the viewport pass and report the presentation path accurately. No additional viewport cache is allocated.
Preserve exact held/released assertions and cover odd/even/fractional pans at DPR 1, 1.25, 1.5 and 2. Verify native picture and backing identity reuse; update one pixel in the existing baseline only after proving equality with direct rendering.
Validation: full check, 735 scoped unit tests, and 58 targeted browser tests pass. The targeted set still excludes the previously classified paint-field-width baseline. An additional tiled large-blur test fails identically on parent d16400b3e, with byte-identical actual PNGs. Broader release acceptance remains separate.
Unify preview-aware transforms across scene drawing, labels, selection and input. Give live property and creation edits explicit preview ownership, preserve cancellation and one-step undo, and reuse bounded text preparation resources.
Include retained device-grid handling, worktree HMR coverage, and nested/reflected interaction regressions in this cohesive progress checkpoint.
Validation: full check passes; 734 scoped unit tests and 53 targeted browser tests pass. This is NOT merge-ready: the unchanged exact nested filled-section held/released regression still fails with 63 differing pixels (maximum channel delta 5/255). The browser pass count excludes that separately run failure and the previously classified paint-field-width baseline. Raster-origin investigation and broader acceptance remain outstanding.
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.
Share canonical tool inputs with AI and browser adapters through Valibot and Standard Schema while retaining MCP numeric coercion and existing transports.
BREAKING CHANGE: programmatic integrations use SDK v2 server/client types; paramToZod is removed in favor of the shared Core tool input contract.
Publish committed history changes independently of scene mutations so menus observe history recorded after the final draw. Align the assets regression with the documented top-left default.
Reject unknown or incompatible references while the owning component definitions are available, including inherited component-set definitions. Keep nested component scopes separate.
Import the skill and its license from open-pencil/skills at 623927958f277b0d8810a2582a38ae24409f7577. Keep agent-facing examples with their implementation and use runtime tool discovery instead of a stale inventory.
