Designs durable API contracts across REST, GraphQL, gRPC, tRPC, and AsyncAPI. Use when specifying interfaces, auth, versioning, errors, rate limits, or agent APIs.
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 Use this skill for contract-first API design across REST, GraphQL, gRPC, tRPC, AsyncAPI, and agent-facing interfaces. It owns contract choice, auth boundaries, versioning, errors, pagination, rate limits, idempotency, and validation; it does not replace backend implementation or security review. ## Style Decision Table | API style | Choose when | Avoid when | Canonical artifact | |-----------|-------------|------------|--------------------| | REST + OpenAPI | Public APIs, broad tooling compatibility, cacheable resources | Streaming-first service contracts | OpenAPI 3.x | | GraphQL | Complex client-driven query shapes, multi-team schema ownership | Simple CRUD, caching is critical, single-team | GraphQL SDL | | gRPC | Internal services, bidirectional streaming, type-critical boundaries | Public internet consumers, browser-native clients | protobuf | | tRPC | TypeScript monorepos with shared server+client | Non-TS stacks, public third-party consumers | TypeScript types | | AsyncAPI + webhooks | Event-driven contracts, pub/sub, push notifications | Synchronous request-reply | AsyncAPI 3.x | …

How to install
mdr add vasilyu1983/ai-agents-public/dev-api-design@sha256:61ecfdf907bbb66dThe line at the top of this page pins the label v1.2, 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.
