+
+# D.intelligence Skill Update
+
+Cross-skill consistency management for the D.intelligence Agent Corps. Triggered by Andrew only.
+
+## Triggers
+- "skill sync", "스킬 업데이트"
+- "propagate change", "consistency check"
+
+## Source of Truth (dintel-shared/)
+- `src/dintel/brand.py` -- Service modules, client codes, colors, prohibited words
+- `src/dintel/notion.py` -- DB IDs, status options, field definitions
+- `src/dintel/document.py` -- DOCX utilities
+- `src/dintel/excel.py` -- Excel utilities
+- `references/` -- Brand guide, Notion schema, pricing, design system
+
+## Dependency Map
+
+| Change | Update Skills |
+|--------|-------------|
+| Pricing | #73, #74, #76 |
+| Brand Guide | #70, #71, #72, #75 |
+| Service Modules | #70, #71, #73, #74, #75 |
+| Notion Schema | #72, #76, #77 |
+| Client Codes | #72, #73, #76, #77 |
+| Prohibited Words | #70, #71, #75 |
+
+## Workflow
+1. Andrew describes change
+2. Look up Dependency Map -> list affected skills
+3. Present Impact Report -> wait for approval
+4. Update `dintel-shared/` first (source of truth)
+5. Propagate to each affected skill
+6. Run consistency verification
+7. Log to `shared/change-log.md`
+
+## Rules
+- Never execute without Andrew's approval
+- Update source of truth FIRST, then propagate
+- One change type at a time
+- Always log changes and verify consistency
