What the reviewer found

In-repo MCP setup skill for this project's own 'fitness' add-on, identical pattern to body-mcp-setup: all URLs ($BOARD_URL, the :8011 bridge) are localhost, and the .mcp.json check targets the project's own generated config. No external host or remote code execution.

How this review was made

Sonnet 5 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
