Design and implement validated, authenticated APIs with clear error contracts and safe lifecycle handling.
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 development skill 1. Read the existing API conventions and call sites before adding routes, dependencies, or new abstractions. 2. Validate HTTP method, path parameters, request content type, body size, object shape, field types, and allowed values before performing side effects. 3. Use explicit authentication and authorization. Treat CORS and same-origin checks as defense-in-depth, not substitutes for authentication. 4. Return consistent status codes and bounded error messages; do not leak API keys, environment variables, stack traces, or internal filesystem details. 5. Bound concurrent work, request duration, output/event history, and resource cleanup. Make retries and duplicate submissions safe where practical. 6. Use parameterized/argv-based process execution rather than shell interpolation. Require approval for consequential side effects and explain what approval permits. 7. Test unauthenticated, malformed, oversized, cross-origin, duplicate, timeout, and error-path behavior using temporary resources and mocked external services. 8. Document the trust boundary, deployment assumptions, and any remaining rate-limit, transport-encryption, or sandbox limitations.

How to install
mdr add fahthiz/oasis/api-development@sha256:2ebda0913dbfdb25The line at the top of this page pins the label git:20261027.0a88cfe, 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.
