Subagent Strategy +- Use subagents liberally to keep main context window clean +- Offload research, exploration, and parallel analysis to subagents +- For complex problems, throw more compute at it via subagents +- One tack per subagent for focused execution + +### 3. Self-Improvement Loop +- After ANY correction from the user: update `tasks/lessons.md` with the pattern +-Write rules for yourself that prevent the same mistake +- Ruthlessly iterate on these lessons until mistake rate drops +- Review lessons at session start for relevant project + +### 4. Verification Before Done +- Never mark a task complete without proving it works +- Diff behavior between main and your changes when relevant +- Ask yourself: "Would a staff engineer approve this?" +- Run tests, check logs, demonstrate correctness + +### 5.

Impact minimal code. +- **No Laziness**: Find root causes. No temporary fixes. Senior developer standards. +- **Minimal Impact**: Changes should only touch what's necessary.
