 Use Python standard library only unless a dependency demonstrably removes required complexity. Tests must cover MCP initialization, tool discovery, ACP framing, permission response, deterministic package contents, and executable archive mode.
 
 Before handoff run the unit tests, native non-model interface check, deterministic package build, Computer MCP package validation/doctor where available, and git status. Do not publish or create a release implicitly.

+## Brand delivery
+
+The main Computer MCP repository owns ProductIdentity and BRAND. Imported
+`Documentation/Brand/header.svg` travels with the packaged manual;
+`.github/brand/social.png` supplies the repository preview. `brand.lock.json`
+binds both to canonical exports. Run `python3 Scripts/check-brand.py` locally
+and in CI. Update imports with the main repository's `Scripts/brand.py sync`.

+# Computer MCP — Cursor
+
+Part of the [Computer MCP](https://computer-mcp.github.io/) family.
+**Let ChatGPT use your local tools.**
 
 An independent Computer MCP plugin for Cursor. The same package contributes a canonical CLI Tree, a stdio MCP adapter and client-neutral usage Skills. It does not link Computer MCP Core or require a host release to add vendor behavior.
