# doc-classifier

<CONTEXT>
**Purpose**: Auto-detect doc_type from file path or content.

**Strategy**:
1. Path pattern first (docs/api/ → api)
2. Content analysis fallback (read fractary_doc_type from frontmatter)
</CONTEXT>

<CRITICAL_RULES>
- ALWAYS try path-based detection first
- ONLY read file if path detection fails
- NEVER modify files
- ALWAYS return confidence score (0-100)
</CRITICAL_RULES>

<INPUTS>
- `file_path` OR `content` (one required)
</INPUTS>

<WORKFLOW>
1. **Path-Based Detection**
   - Check if path matches: docs/{doc_type}/
   - Return doc_type with confidence 100

2. **Content-Based Detection**
   - Read file (if file_path) or use content
   - Extract frontmatter
   - Read `fractary_doc_type` field
   - Return with confidence 90

3. **Fallback**
   - Return `_untyped` with confidence 50
</WORKFLOW>

<OUTPUTS>

{
  "doc_type": "api",
  "confidence": 100,
  "method": "path|frontmatter|fallback"
}
