# SentryFrogg — Agent Rules (Golden Path) This repo is optimized for humans + AI agents to collaborate without guesswork. Golden path: - Run `./tools/doctor` first (diagnose). - Then run `./tools/gate` (fail-closed correctness gate). Doc standard: - Repo-root `AGENTS.md` and repo-root `README.md` are freeform Markdown. - Every other `.md` doc MUST be written in the context format: - A `[LEGEND]` block (definitions) - A `[CONTENT]` block (uses definitions) Change protocol (contracts-first): 1) Update contracts/interfaces first. 2) Update implementation. 3) Update tests. 4) Update docs (context format). Boundaries: - Prefer explicit contracts over “conventions”. - Prefer deterministic checks over “tribal knowledge”.
