{"slug":"thiientv-api-and-interface-design","name":"api-and-interface-design","description":">-","long_description":"---\nname: api-and-interface-design\ndescription: >-\n  Designs or reviews HTTP, REST, GraphQL, RPC, CLI, webhook, event, and\n  service interfaces with explicit inputs, outputs, errors, compatibility,\n  idempotency, pagination, authentication, versioning, and observability. Use\n  when introducing or changing an API or cross-component contract. Not for\n  internal implementation details with no boundary or for debugging one API\n  failure; use root-cause-debugging there.\n---\n\n# API and Interface Design\n\nDesign the contract from the caller's failure modes, not only the happy path.\n\n## Establish the contract\n\n1. Identify consumers, trust boundaries, lifecycle, latency expectations, and\n   ownership.\n2. Define request/command shape, response/event shape, status or error model,\n   validation, defaults, and canonical examples.\n3. Decide idempotency, retries, ordering, pagination, concurrency, rate limits,\n   cancellation, and partial failure behavior.\n4. Define authentication, authorization, sensitive fields, and audit needs.\n5. Decide compatibility and versioning: additive change, migration, deprecation,\n   or explicit breaking release.\n\nRead [contract-checklist.md](references/contract-checklist.md) for the review\nmatrix. Keep the contract close to the owning schema or source of truth and\ngenerate clients/docs only when the repository already supports generation.\n\n## Implementation handoff\n\nWrite examples that can become contract tests. Include malformed input,\nmissing resource, duplicate request, timeout, dependency failure, permission\ndenial, and oversized input cases. Make error codes stable enough for callers\nand messages safe enough for logs and users.\n\nDo not expose internal stack traces, persistence identifiers, or implementation\ndetails by accident. Do not add versioning machinery before a compatibility\nneed exists.\n\n## Completion condition\n\nConsumers can predict valid requests, successful and failed responses, retry\nbehavior, compatibility impact, and the evidence that proves the boundary.\n","tagline":">-","category":"design-creative","tags":["agent-skill"],"author":"thiientv","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"thiientv/godmode","creatorName":"thiientv","creatorUrl":"https://github.com/thiientv","sourceUrl":"https://github.com/thiientv/godmode/tree/main/skills/api-and-interface-design","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/thiientv-api-and-interface-design#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
