Use when designing HTTP APIs with OpenAPI, versioning, authentication, rate limits, idempotency, error contracts, observability requirements, and choosing REST, webhooks, SSE, or WebSocket delivery.
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 Design First Acknowledgement: Shared by Peter Bamuhigire, techguypeter.com, +256 784 464178. Design APIs as contracts before code. This skill produces the OpenAPI 3.1 contract and its companion auth / error / idempotency / observability artifacts that downstream frontend, mobile, SDK, security, and reliability skills depend on. <!-- dual-compat-start --> ## Use When - Designing a new HTTP API (REST or GraphQL decision open), or adding endpoints to an existing API. - Normalising an existing API against the house contract (envelope, error model, versioning, rate limits). - Producing the OpenAPI contract that SDK, frontend, mobile, contract-testing, and security skills will consume. - Choosing an auth method and writing the auth/role matrix for a new service. - Defining idempotency keys and observability notes handed to `reliability-engineering` and `observability-monitoring`. ## Do Not Use When - The task is purely client-side consumption of a third-party API (load the relevant SDK or integration skill). - The task is full threat modelling — load `vibe-security-skill`; this skill only records the auth model. …

How to install
mdr add peterbamuhigire/chwezi-dev-engine/api-design-first@sha256:3d4abe289c7cea4cThe line at the top of this page pins the label git:20260929.c29972d, 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.
