Use when asked to design or change a public API, route, CLI flag, or module boundary. Not for remote, credential, publish, deploy, or irreversible changes.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# API and interface design

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Designing or changing a public API, route, CLI flag, or module boundary. |
| Authority | Reversible local: writes only named local interface definitions and contract docs, edits consumer files onto the new contract, and deletes legacy paths (old signatures, aliases, re-exports, deprecated entry points) during cutover; rollback is undo (discard the uncommitted draft) or version control. No remote mutation. No credential, paid, published, or deployed change, and no VCS history rewrite. |
| Side effect | Interface definitions and contract docs written before implementation; consumer files edited onto the new contract and legacy paths (old signatures, aliases, re-exports, deprecated entry points) deleted during cutover; no build, publish, or remote mutation. |
| Done | Contract is documented with semantics and errors, every consumer is migrated, and no legacy path remains. |
