# API Error Handling ## Use this skill when - Defining a standard error contract - Returning precise error codes and messages - Adding error context without leaking internals ## Do not use this skill when - Internal error logging (use backend-error-handling) ## Instructions 1. Return a structured error body: code, message, details/fields, traceId. 2. Include a stable, machine-readable error code per failure kind. 3. Provide field-level validation errors; mention constraints in the message. 4. Use 4xx for client errors and 5xx for server errors; never 200 for failures. 5. Correlate errors with request tracing. 6. Do not leak stack traces, SQL, or internal paths. 7. Document the error taxonomy in the API spec. ## Output Format - Error schema | code taxonomy | per-endpoint error matrix ## Common Mistakes - 200 with an error payload - Free-text messages only - Exposing stack traces to clients
