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
+++ name = "api-design" description = "Use when designing or reviewing an API contract — REST, GraphQL, RPC, webhooks, events. Resources, methods, status codes, validation, error shape, idempotency, caching, versioning." +++ # API Design ## When to use Designing a new endpoint, service, or event contract — or reviewing an existing one for correctness, consistency, and evolvability. **Scope.** This skill decides the *contract*: what the API promises to callers. It never assumes a language, framework, runtime, or architecture — those are the repository's decisions and live in its own `AGENTS.md`. Apply the contract to whatever stack the repo already chose; when a framework idiom conflicts with a rule here, name the conflict instead of silently bending either side. ## Method 1. **Name the consumers** and what each needs. A contract with no named consumer is speculation. 2. **Model the resource** — its identity, representation, and lifecycle (states and legal transitions). 3. **Specify each operation**: method, path, request schema, response schema, status codes, authz rule. 4. **Specify the failure modes** — every error a caller must handle, with its shape and status. …

How to install
mdr add atnexuslab/tightship/api-design@sha256:abd73ff4f00b6f77The line at the top of this page pins the label git:20261015.8e86e2c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
