| description | Create Trae IDE rules (.trae/rules/*.md) for AI behavior constraints. Use when user wants to: create a project rule, set up code style guidelines, enforce naming conventions, make AI always do X, or customize AI behavior for specific files. Triggers on: '创建 rule', 'project rule', '.trae/rules/', 'AGENTS.md', 'CLAUDE.md', 'make AI always use PascalCase'. Do NOT use for skills (use trae-skill-writer) or agents (use trae-agent-writer). |
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

| Apply Intelligently | description: "When doing X..." | Context-dependent guidance |
| Manual Only | (no frontmatter) | Invoke with #RuleName |

User: "Create rules for this TypeScript React project"
Analysis:
- Structure: src/components/, src/hooks/
- Naming: PascalCase components, camelCase functions
- No existing .trae/rules/

# Code Style
- PascalCase for components and types
- camelCase for functions and variables

# React Patterns
- Use functional components with hooks
- Custom hooks go in src/hooks/
