refactor: Reorganize skill numbering and update documentation

Skill Numbering Changes:
- 01-03: OurDigital core (was 30-32)
- 31-32: Notion tools (was 01-02)
- 99_archive: Renamed from _archive for sorting

New Files:
- AGENTS.md: Claude Code agent routing guide
- requirements.txt for 00-claude-code-setting, 32-notion-writer, 43-jamie-youtube-manager

Documentation Updates:
- CLAUDE.md: Updated skill inventory (23 skills)
- AUDIT_REPORT.md: Current completion status (91%)
- Archived REFACTORING_PLAN.md (most tasks complete)

Removed:
- ga-agent-skills/ (moved to separate repo ~/Project/dintel-ga4-agent)

+
+## Overview
+
+Notion workspace management toolkit for database organization, schema migration, and bulk operations.
+
+## Quick Start
+
+```bash
+pip install -r scripts/requirements.txt
+
+# Schema migration
+python scripts/schema_migrator.py --source [DB_ID] --target [DB_ID] --dry-run
+
+# Async bulk operations
+python scripts/async_organizer.py --database [DB_ID] --action cleanup
+```
+
+## Scripts
+
+| Script | Purpose |
+|--------|---------|
+| `schema_migrator.py` | Migrate data between databases with property mapping |
+| `async_organizer.py` | Async bulk operations (cleanup, restructure, archive) |
+
+## Schema Migrator
+
+```bash
+# Dry run (preview changes)
+python scripts/schema_migrator.py \
+  --source abc123 \
+  --target def456 \
+  --mapping mapping.json \
+  --dry-run
+
+# Execute migration
+python scripts/schema_migrator.py \
+  --source abc123 \
+  --target def456 \
+  --mapping mapping.json
+```
+
+### Mapping File Format
+
+```json
+{
+  "properties": {
+    "OldName": "NewName",
+    "Status": "Status"
+  },
+  "transforms": {
+    "Date": "date_to_iso"
+  }
+}
+```
+
+## Async Organizer
+
+```bash
+# Cleanup empty/stale pages
+python scripts/async_organizer.py --database [ID] --action cleanup
+
+# Archive old pages
+python scripts/async_organizer.py --database [ID] --action archive --days 90
+
+# Restructure hierarchy
+python scripts/async_organizer.py --database [ID] --action restructure
+```
+
+## Rate Limits
+
+| Limit | Value |
+|-------|-------|
+| Requests/second | 3 max |
+| Items per request | 100 max |
+| Retry on 429 | Exponential backoff |
+
+## Configuration
+
+Environment variables:
+```bash
+NOTION_TOKEN=secret_xxx
+```
+
+## Notes
+
+- Always use `--dry-run` first for destructive operations
+- Large operations (1000+ pages) use async with progress reporting
+- Scripts implement automatic rate limiting

+
+## Workflow Patterns
+
+### Pattern 1: Database Audit
+
+**Purpose**: Analyze database structure and recommend optimizations
+
+**Steps**:
+1. Fetch database schema via MCP or API
+2. Analyze property types, naming conventions, usage
+3. Identify issues:
+   - Unused properties
+   - Inconsistent naming
+   - Suboptimal property types
+   - Missing relations
+4. Present recommendations with rationale
+5. Execute approved changes incrementally
+
+**Example Query**:
+```
+Audit my "Projects" database:
+- Check for unused properties
+- Identify naming inconsistencies
+- Recommend schema optimizations
+```
+
+### Pattern 2: Bulk Reorganization
+
+**Purpose**: Move/update many pages efficiently
+
+**Decision Tree**:
+- ≤ 50 operations → Use MCP tools with staged execution
+- > 50 operations → Generate Python script
+
+**Steps**:
+1. Assess scope (count affected pages)
+2. Estimate API calls and time
+3. Choose execution method (MCP vs Python)
+4. Execute with progress updates
+5. Generate summary report
+
+**Example Query**:
+```
+Move all pages with status "Archived" from "Active Projects"
+to "Archive" database, preserving the Project Name and Date properties
+```
+
+### Pattern 3: Schema Migration
+
+**Purpose**: Transfer data between databases with different schemas
+
+**Steps**:
+1. Fetch source database schema
+2. Fetch target database schema
+3. Create property mapping plan:
+   - Direct mappings (same type)
+   - Transformations needed (type conversion)
+   - Unmappable properties (manual handling)
+4. Validate compatibility
+5. Execute migration:
+   - MCP for small datasets
+   - Python for large datasets
+6. Verify data integrity
+
+**Property Mapping Template**:
+```
+Source Property → Target Property (Transformation)
+─────────────────────────────────────────────────
+Name (title)    → Project Name (title)     [Direct]
+Status (select) → Stage (status)           [Map values]
+Due Date (date) → Deadline (date)          [Direct]
+Tags (multi)    → Categories (multi)       [Merge options]
+Notes (text)    → Description (text)       [Direct]
+Owner (text)    → Assignee (people)        [Manual]
+```
+
+### Pattern 4: Property Cleanup
+
+**Purpose**: Standardize properties across databases
+
+**Common Tasks**:
+- Rename properties to consistent convention (camelCase, snake_case, Title Case)
+- Consolidate duplicate select/multi-select options
+- Remove unused properties
+- Add missing required properties
+
+**Naming Convention Guide**:
+```
+Recommended: Title Case with spaces
+Examples: "Project Name", "Due Date", "Status", "Assigned To"
+
+Alternative: camelCase (for technical databases)
+Examples: "projectName", "dueDate", "status", "assignedTo"
+```
+
+### Pattern 5: Duplicate Detection
+
+**Purpose**: Find and handle duplicate or similar content
+
+**Detection Strategies**:
+1. Exact title match
+2. Fuzzy title similarity (Levenshtein distance)
+3. Property combination match (e.g., same name + date)
+4. Content hash comparison
+
+**Resolution Options**:
+- Merge: Combine properties from duplicates
+- Archive: Move older duplicate to archive
+- Delete: Remove with user confirmation
+- Link: Create relation between related items
+
+---
+
+## MCP Tool Usage Examples
+
+### Search for Pages
+```
+Use mcp__notion__search to find:
+- Query: "marketing campaign"
+- Filter: database_id = "abc123"
+```
+
+### Query Database with Filters
+```
+Use mcp__notion__query-database:
+- Database ID: "abc123"
+- Filter: { "property": "Status", "select": { "equals": "Active" } }
+- Sorts: [{ "property": "Created", "direction": "descending" }]
+```
+
+### Update Page Properties
+```
+Use mcp__notion__update-page:
+- Page ID: "xyz789"
+- Properties: {
+    "Status": { "select": { "name": "Completed" } },
+    "Completed Date": { "date": { "start": "2025-12-05" } }
+  }
+```
+
+### Create New Page
+```
+Use mcp__notion__create-page:
+- Parent: { "database_id": "abc123" }
+- Properties: {
+    "Name": { "title": [{ "text": { "content": "New Project" } }] },
+    "Status": { "select": { "name": "Planning" } }
+  }
+```
+
+---
+
+## Best Practices
+
+### 1. Always Fetch Before Modify
+Never assume database structure. Always retrieve current schema first.
+
+### 2. Batch Operations Wisely
+- Group related updates
+- Use pagination for queries
+- Implement checkpoints for large operations
+
+### 3. Handle Relations Carefully
+- Relations require both databases to be accessible
+- Synced databases need special handling
+- Rollups depend on relations - update order matters
+
+### 4. Preserve Data Integrity
+- Back up critical data before major changes
+- Use transactions where possible
+- Verify changes after execution
+
+### 5. Respect User Permissions
+- Check integration has access to target resources
+- Request additional permissions when needed
+- Document permission requirements
