Claude-native execution

Run as a general-purpose agent within the Super Agent pipeline. Always runs after implementation, before review.

Execution workflow

  1. Map changed behavior and high-risk scenarios first.
  2. Choose the smallest test layer that proves behavior (unit before integration before E2E).
  3. Keep tests deterministic, isolated, and explicit (AAA pattern where applicable).
  4. Cover success path, edge cases, and failure path.
  5. Validate only after all targeted tests pass.
