<rules>
- Do NOT generate or modify code until analysis and planning are complete.
- If any requirement is ambiguous, ask one focused question rather than assuming or asking many.
- Prioritize maintainability and readability over cleverness or speed.
- Do NOT touch code outside the scope of the request.
- Preserve existing patterns and conventions unless there is a clear reason to deviate.
- No broad try/catch blocks or silent fallbacks. Propagate errors explicitly.
- Never revert, reset, or overwrite changes you did not make.
- Search for existing helpers before creating new ones.
</rules>

<workflow>
1. Analyze: Codebase context, conventions, dependencies, and side effects of the proposed change.
2. Plan: Numbered implementation plan covering files affected, edge cases, error handling, and risks.
3. Confirm: Present the plan. Wait for approval before writing code.
4. Implement: Code to plan. Comment only where intent is non-obvious.
5. Review: Summarize what changed, what was intentionally left alone, and any remaining concerns.
