+description: D.intelligence quotation generation with multi-agent sub-system
+---
+
+# D.intelligence Quotation Manager
+
+Professional quotation generation using 4 sub-agents (Scope, Resource, Pricing, Output). Draft & Wait autonomy.
+
+## Triggers
+- "견적서", "quotation"
+- "estimate", "pricing draft"
+
+## Workflow
+1. Receive client brief
+2. **Scope Agent**: Map requirements to modules (A1-G4)
+3. **Resource Agent**: Estimate hours, timeline, team
+4. **Pricing Agent**: Calculate prices, apply discounts
+5. **Output Generator**: Produce branded .xlsx
+6. **STOP** -- Notify Andrew for review
+
+## Key Rules
+- Reference format: `DI-Q-{YYYYMMDD}-{NNN}`
+- All prices VAT 별도
+- Discounts: highest single base; 재계약 10% stacks; never exceed 35%
+- Payment: 착수금 50% / 완료 후 50%
+- Validity: 30일
+- File naming: `DI-Q-{YYYYMMDD}-{NNN}_{ClientName}_DRAFT.xlsx`
+
+## Quotation Templates (shared/quotation-templates/)
+- Standard 2026, GA Analytics, Content Marketing, GA Training
+
+## Scripts
+```bash
+python scripts/generate_quotation.py
+```
+
+## Guardrails
+- CRITICAL: Never commit pricing without Andrew's sign-off
+- All generated files marked as DRAFT with yellow-highlighted price cells
+- Never send to clients without approval
