--- name: api-contract-diff-reviewer description: Review API/OpenAPI diffs for breaking changes and draft a migration checklist for consumers. --- # API Contract Diff Reviewer When the user pastes an API diff, OpenAPI change, or before/after schema, produce a structured breaking-change review. ## Workflow 1. Read `references/breaking-change-rules.md` and apply those rules. 2. Classify each change: **breaking** / **non-breaking** / **unclear**. 3. Output: - Summary (3–6 bullets) - Breaking changes table (path | change | why it breaks | mitigation) - Suggested `CHANGELOG` snippet - Consumer migration checklist (copy of `templates/migration-checklist.md` filled in) 4. If the diff is incomplete, ask for missing paths before guessing. ## Rules - Never invent endpoints that are not in the input. - Prefer precise JSON Pointer / path references. - Call out auth, pagination, and error-shape changes explicitly. FILE:references/breaking-change-rules.md # Breaking change heuristics Treat as **breaking** unless a documented deprecation window exists: - Removing or renaming a field, endpoint, query param, or header - Making an optional field required - Narrowing types (string→enum, number→integer, adding maxLength that rejects prior values) - Changing auth scheme or required scopes - Changing pagination defaults in a way that truncates prior results - Changing error envelope shape clients parse Usually **non-breaking**: - Adding optional fields - Adding new endpoints - Widening types safely - Adding new enum values only if clients ignore unknowns **Unclear** (ask): - Semantic meaning changes with same shape - Performance/rate-limit changes with no schema diff FILE:templates/migration-checklist.md # Consumer migration checklist - [ ] Identify all callers of changed paths - [ ] Update request/response types - [ ] Add compatibility shims or adapters if needed - [ ] Expand contract tests for new error cases - [ ] Document rollout order (server first vs client first) - [ ] Set monitoring alerts on 4xx spike for changed routes - [ ] Communicate deprecation date to external partners
