XcodeBuildMCP Snapshot Fixture Review

Review guardrails for fixture and snapshot contract integrity.

Review scope

  • Review-only by default.
  • Do not edit product code unless the user explicitly requests implementation changes.

Files to inspect

  • src/snapshot-tests/__fixtures__/**
  • src/snapshot-tests/contracts.ts
  • src/snapshot-tests/fixture-io.ts
  • src/snapshot-tests/__tests__/fixture-io.test.ts
  • src/snapshot-tests/__tests__/json-normalize.test.ts
  • src/snapshot-tests/__tests__/json-fixture-schema.test.ts
  • xcodebuildmcp.com/app/docs/_content/testing.mdx

Guardrails

  • Fixture updates map to intentional behavior changes.
  • Do not update fixtures only to make tests pass.
  • MCP, CLI, and JSON fixture updates stay aligned.
  • JSON fixtures preserve stable structured output envelopes.
  • Volatile values are normalized in code, not patched ad hoc in fixtures.
  • Missing fixtures are generated through the snapshot update flow.

Validation

  • npm run test:snapshots
  • npm run test:schema-fixtures
  • npm test -- src/snapshot-tests/__tests__/fixture-io.test.ts
  • npm test -- src/snapshot-tests/__tests__/json-normalize.test.ts
  • npx skill-check .agents/skills/xcodebuildmcp-snapshot-fixture-review
