SKILL.md (first lines)
- Define actors, trust zones, resources, operations, and compatibility expectations. - Accept forgiving input only where normalization is unambiguous; keep output strict. - Return machine-readable error codes with useful human messages. - Report all independent validation errors when doing so is safe. - Separate liveness, readiness, and metrics endpoints. - Include realistic request, response, auth, failure, pagination, and idempotency examples. - Test authorization boundaries and backwards compatibility, not only happy paths.
