* chore: prefer es-toolkit helpers and lint the mechanical cases AGENTS.md now names the es-toolkit helpers to reach for instead of hand-written equivalents, and the exceptions: a single clear native call or a measured hot path. The new open-pencil/prefer-es-toolkit rule rejects filter(Boolean) and Set round trips on arrays, the two cases that need no type information, and the existing 45 sites use compact and uniq. tools/ci/policy runs before dependencies are installed, so the rule is off there. * refactor: deduplicate diagnostic categories with uniq * fix: keep es-toolkit out of serialized Playwright callbacks The codemod rewrote a filter(Boolean) inside a page.evaluate callback, which Playwright runs in the page where the compact import does not exist. The spec filters there again, and the rule now skips callbacks passed to evaluate, $eval, $$eval, evaluateHandle, addInitScript and waitForFunction, and filter calls on iterators from values, keys, entries and matchAll, which compact cannot take. * test: write the prefer-es-toolkit cases like the other rule tests Short standalone snippets, as in the base64 and JSON rule tests, instead of a declaration prefix on every case and inline object types. |

@open-pencil/mcp
Model Context Protocol server for OpenPencil. It lets MCP clients such as Claude Code, Cursor, and Windsurf inspect and edit designs through the running app, reusing the same tool definitions as the built-in AI chat.
npm install -g @open-pencil/mcp
openpencil-mcp # stdio transport for MCP clients
openpencil-mcp-http # Streamable HTTP transport for browser extensions and scripts
On macOS and Linux, local clients prefer a private Unix domain socket; Windows and unavailable sockets fall back to localhost TCP. File access is limited to the effective MCP root.
