Craftwork

Find root cause before attempting fixes — 4-phase investigation, never guess-fix

Handle code review feedback with technical rigor — verify before implementing, push back if incorrect, no performative agreement

Review diffs with structured checklist — spec compliance, security, tests, breaking changes, code quality

Write failing test first, then implement minimal code to pass, then refactor — no production code without a failing test

Spawn multiple subagents simultaneously for independent tasks with no shared state — maximize throughput safely

Run verification commands and confirm output before claiming any work is complete — evidence before assertions
