* fix: validate parsed JSON at untrusted boundaries with Valibot Clipboard HTML, library revisions from shared storage, MCP and automation WebSocket messages, the MCP discovery file, sidecar output and AI/MCP tool arguments were JSON.parse'd and cast to their expected types, so a malformed payload reached the document or crashed paste. They now go through v.pipe(v.string(), v.parseJson(), Schema), which reports bad JSON and a wrong shape as the same validation failure. The path_set tool rejects an invalid VectorNetwork and shares its parser with create_vector. The CLI library catalog validates its files and runs revisions through the same size, identity and content-hash checks as the app; reading image bytes as index-keyed records also stops them coming back empty. Hand-rolled typeof readers for plugin data, document metadata, caches and preferences become schemas with their behaviour preserved, and readCacheJSON takes a schema for its payload. open-pencil/no-unvalidated-json-parse rejects type assertions on JSON.parse results other than `as unknown` in src and packages/*/src. * refactor: validate parsed JSON in tests and tooling Extend open-pencil/no-unvalidated-json-parse beyond source: tests, helpers and repo tooling now parse JSON through Valibot schemas instead of asserting a type. The shared fixture reader returns a validated object; its old array annotation never matched the fixtures. * fix: validate clipboard geometry bytes, library images and model catalogs Clipboard geometry blobs and library image bytes must be bytes at contiguous indexes, so out-of-range or gapped values are rejected instead of silently becoming different geometry or images; serialized library nodes must carry source metadata. The models.dev and OpenRouter responses are validated like their cached copies, and activate-tab rejects a CDP frame it cannot read instead of hanging. * refactor: extend the JSON validation lint to .json() results no-unvalidated-json-parse now also rejects type assertions on Response, Bun.file and shell .json() results, the same unchecked parse in another form. MCP server tests read /health through a validated readHealth helper and discovery files through parseDiscoveryInfo; the remaining tooling reads its JSON through schemas. * test: validate the RPC request body in the CLI app export test * test: validate CLI JSON output in the tool and app command tests * test: compare the malformed models.dev fallback with the curated list |

@open-pencil/cli
Headless command line for OpenPencil and .fig files: inspect documents and layers, query with XPath, export to PNG, JPG, WEBP, SVG, PDF, PPTX, JSX, HTML, or .fig, import HTML/CSS/Tailwind, lint design files, analyze and extract design tokens, and script documents with a Figma Plugin API-compatible figma global through eval.
npm install -g @open-pencil/cli # or: bun add -g @open-pencil/cli
openpencil --help
openpencil eval design.fig -c "return figma.currentPage.children.length"
Inspection commands support --json for automation. The MCP server ships separately as @open-pencil/mcp.
