Gemini CLIAbout this skill
Designs backend API error contracts with a REST-default approach using RFC 9457 Problem Details, stable machine-readable codes, retry semantics, validation error payloads, observability, and security-safe messaging. Reviews existing error handling against a binary rubric and proposes concrete fixes. Produces optional artifacts such as errors.yaml entries, Problem Details examples, OpenAPI fragments, and runbook templates. Use when creating or revising backend error responses, auditing API error quality, mapping status/code behavior, or documenting error handling for REST, gRPC, GraphQL, and async services.
