Deterministic test-suite integrity checks for AI-assisted Python and pytest pull requests.
Your build is green — but did the agent make it green by weakening the tests? mumei re-runs them from a clean HEAD, freezes what must not be tuned, and reads the diff for deleted tests and suppressed errors. Enforced in Hooks, not asked for in a prompt.
Nine deterministic hooks that block a coding agent from weakening tests, swallowing errors, or stubbing type checks — each backed by a planted-failure test proving the guard can actually fire. Runs on Claude Code and DeepSeek Harness.
Test-integrity firewall for coding agents that protects trusted tests and binds completion evidence to the checked repository state.
Test integrity for AI coding agents: the context that grades the tests is isolated from the one that writes the code, and test quality is enforced by scripts with real exit codes — not prose. Claude Code plugin: /fofo:sdlc
