About this skill

Investigate

Rules

  • no speculative fixes
  • gather evidence before changing code
  • separate observations, hypotheses, and fixes

Workflow

  1. Reproduce the issue and capture exact symptoms.
  2. Trace the real execution path.
  3. Form the smallest plausible root-cause hypothesis.
  4. Verify the hypothesis against code or runtime evidence.
  5. Only then propose or implement a fix.
