+## Workflow Orchestration
 
-This repository uses `AGENTS.md` as the canonical instruction file for all coding agents.
+### 1. Plan Mode Default
+- Enter plan mode for ANY non-trivial task (3+ steps or architectural decisions)
+- If something goes sideways, STOP and re-plan immediately - don't keep pushing
+- Use plan mode for verification steps, not just building
+- Write detailed specs upfront to reduce ambiguity
 
-If your tool auto-loads `CLAUDE.md`, apply the rules from `AGENTS.md`.
+---
+
+### 2. 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 task 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. Demand Elegance (Balanced)
+- For non-trivial changes: pause and ask "is there a more elegant way?"
+- If a fix feels hacky: "Knowing everything I know now, implement the elegant solution"
+- Skip this for simple, obvious fixes - don't over-engineer
+- Challenge your own work before presenting it
+
+---
+
+### 6. Autonomous Bug Fixing
+- When given a bug report: just fix it. Don't ask for hand-holding
+- Point at logs, errors, failing tests - then resolve them
+- Zero context switching required from the user
+- Go fix failing CI tests without being told how
+
+---
+
+## Task Management
+1. **Plan First**: Write plan to `tasks/todo.md` with checkable items
+2. **Verify Plan**: Check in before starting implementation
+3. **Track Progress**: Mark items complete as you go
+4. **Explain Changes**: High-level summary at each step
+5. **Document Results**: Add review section to `tasks/todo.md`
+6. **Capture Lessons**: Update `tasks/lessons.md` after corrections
+
+---
+
+## Core Principles
+- **Simplicity First**: Make every change as simple as possible. Impact minimal code
+- **No Laziness**: Find root causes. No temporary fixes. Senior developer standards
+- **Minimal Impact**: Changes should only touch what's necessary. Avoid introducing bugs
