Workflow Orchestration

1. Plan Node 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
• Write detailed specs upfront to reduce ambiguity

2. Subagent Strategy

• Use subagents liberally to keep main context window clean
• Offload research, exploration, and parallel analysis to 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
• Review lessons at session start for relevant project

4. Verification Before Done

• Never mark a task complete without proving it works
• 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

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

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. Document Results: Add review section to tasks/todo.md
5. 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.
