Use when reviewing XcodeBuildMCP snapshot fixture changes for MCP, CLI, and JSON output contract integrity.

🧰 Not standalone. This skill ships with getsentry/xcodebuildmcp and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

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
