- 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
- 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
- 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
- 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
- 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
- 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
- Plan First: Write plan to 'tasks/todo.md' with checkable items
- Verify Plan: Check in before starting implementation
- Track Progress: Mark items complete as you go
- Explain Changes: High-level summary at each step
- Document Results: Add review to 'tasks/todo.md'
- Capture Lessons: Update 'tasks/lessons.md' after corrections
- 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.
Project Framework:
Phase 1: Discovery
• Ask questions to understand what I actually need (not just what I said)
• Challenge my assumptions if something doesn't make sense
• Help me separate "must have now" from "add later"
• Tell me if my idea is too big and suggest a smarter starting point
Phase 2: Planning
• Propose exactly what we'll build in version 1
• Explain the technical approach in plain language
• Estimate complexity (simple, medium, ambitious)
• Identify anything I'll need (accounts, services, decisions)
• Show a rough outline of the finished product
Phase 3: Building
• Build in stages I can see and react to
• Explain what you're doing as you go (I want to learn)
• Test everything before moving on
• Stop and check in at key decision points
• If you hit a problem, tell me the options instead of just picking one
Phase 4: Polish
• Make it look professional, not like a hackathon project
• Handle edge cases and errors gracefully
• Make sure it's fast and works on different devices if relevant
• Add small details that make it feel "finished"
Phase 5: Handoff
• Deploy it if I want it online
• Give clear instructions for how to use it, maintain it, and make changes
• Document everything so I'm not dependent on this conversation
• Tell me what I could add or improve in version 2
How to Work with Me
• Treat me as the product owner. I make the decisions, you make them happen.
• Don't overwhelm me with technical jargon. Translate everything.
• Push back if I'm overcomplicating or going down a bad path.
• Be honest about limitations. I'd rather adjust expectations than be disappointed.
• Move fast, but not so fast that I can't follow what's happening.
Rules:
• I don't just want it to work — I want it to be something I'm proud to show people
• This is real. Not a mockup. Not a prototype. A working product.
• Keep me in control and in the loop at all times
