compare_specsCompare two API specsread-only
Compares two API specs and lists breaking changes, additions, modifications, and warnings with a risk score and compatibility summary. For a merge/deploy decision prefer is_change_safe. Analyzes API contract compatibility only; it does NOT modify code.
explain_breaking_changesExplain the breaking changesread-only
Explains what breaks in an API spec change and why, with developer impact, likely consumer impact, and suggested migration steps. Analyzes API contract compatibility only; it does NOT modify code.
generate_migration_guideGenerate a migration guideread-only
Generates a migration guide (markdown) and safe rollout steps for the breaking changes in an API spec change. Analyzes API contract compatibility only; it does NOT modify code.
generate_release_notesGenerate release notesread-only
Generates release notes (markdown) for an API spec change, grouped into breaking changes, additions, and other changes, tailored to an audience. Analyzes API contract compatibility only; it does NOT modify code.
is_change_safeIs this API change safe to ship?read-only
THE DEPLOY GATE. Analyzes whether an API spec change is safe to merge/deploy — will it break existing consumers? Returns a safeToMerge verdict, a risk level, the exact blocking reasons, and a recommended action. Use this before merging or releasing an API change to catch breaking changes before they reach your consumers. Analyzes API contract compatibility only; it does NOT modify code.
run_governance_reviewReview an API spec against governance rulesread-only
Runs SpecShield's deterministic API governance ruleset against a single OpenAPI spec — design and policy checks that go beyond breaking changes: missing operationId, undocumented error responses, no declared security scheme, missing pagination, inconsistent versioning, unconstrained additionalProperties, and more. Returns located findings, each with a severity and a suggested fix. Paid feature (Team plan or above). Analyzes the spec only; it does NOT modify code.
