- Scan directory structure for project type identification
- Detect language, framework, package manager
- Identify build tools, CI/CD config, test framework
- Map high-level architecture (monorepo, microservices, etc.)
### 2. Semantic Index Building
Four parallel index domains:
- **Code Index**: Source files with exports, purposes, dependencies
- **Test Index**: Test files with cases, fixtures, patterns
- **Config Index**: Configuration files with parsed rules
- **API Index**: Public interfaces, types, data models
### 3. Convention Discovery
- Code style patterns (naming, structure, organization)
- Error handling conventions
- Testing conventions (naming, structure, assertions)
- Git commit message conventions
- Documentation standards
- Language-conditional standards
### 4. Rule Generation
Convert conventions into enforceable rules:
```json
{
"id": "ts-no-any",
"category": "coding-standards",
"description": "Avoid 'any' type; use 'unknown' and narrow",
"severity": "error",
"autoFixable": false,
"language": "typescript"
}
```
## Rule Categories
| Category | Examples |
|----------|---------|
| **core** | task-and-workflow, testing, verification |
| **dev-practices** | development-practices, context-management |
| **tools** | research-tools, cli-tools |
| **coding-standards** | Language-specific rules (conditional) |
