# Database Schema ERD
Analyze the database schema and generate an Entity-Relationship Diagram + documentation.
## Instructions
1. Read the primary skill:
- `${CLAUDE_PLUGIN_ROOT}/skills/codemap-diagram/SKILL.md` — ERD generation rules
2. Read ERD-specific guidance from `${CLAUDE_PLUGIN_ROOT}/skills/codemap-diagram/references/diagram-types.md`
3. Ensure output directories exist: `docs/codemap/diagrams/` — create if missing.
4. Launch the **diagrammer** agent with a prompt to:
- Auto-detect the ORM (SQLAlchemy, Prisma, TypeORM, Django, raw SQL migrations)
- Parse all model definitions — tables, columns, types, foreign keys, relationships
- Review schema quality (missing indexes, naming inconsistencies, missing constraints)
- Generate ERD as mxGraph XML → save to `docs/codemap/diagrams/erd.drawio` → call drawio-mcp
- Generate `docs/codemap/DB.md` with table details, relationships, and quality notes
