Trae Rules Writer
Create Trae IDE rules by analyzing project conventions first, then designing rules that match existing patterns.
Workflow
1. ANALYZE → Scan project structure, code style (ls .trae/rules/, cat AGENTS.md)
2. IDENTIFY → What conventions exist? What needs guidance?
3. DESIGN → Choose rule type and application mode
4. CREATE → Write rules in Trae's official format
