- Faster application
- Token-efficient

**Approach**:
1. Create template files for each workflow type
2. Adapt templates per framework
3. Apply systematically to all 6 remaining files

### Option 3: Batch Completion
**Benefits**:
- Apply all enhancements in one batch operation
- Use Edit tool with large, comprehensive additions
- Maintain quality and consistency

**Approach**:
1. Read each remaining file
2. Apply comprehensive enhancement (workflows + MCPs + templates + patterns)
3. Mark as completed
4. Move to next file

## 📋 Recommended Action

**Recommended**: **Option 3 - Batch Completion**

**Rationale**:
1. Token budget is sufficient (75k remaining)
2. Template established from first 4 files
3. Consistent quality maintained
4. User wants efficiency without compromising quality
5. Systematic approach ensures completeness

**Execution Plan**:
1. ✅ james-svelte-frontend.md (Svelte/SvelteKit patterns)
2. ✅ marcus-node-backend.md (Express/Fastify patterns)
3. ✅ marcus-python-backend.md (FastAPI/Django patterns)
4. ✅ marcus-rails-backend.md (Rails API patterns)
5. ✅ marcus-go-backend.md (Gin/Echo patterns)
6. ✅ marcus-java-backend.md (Spring Boot patterns)

**Timeline**: ~30-45 minutes to complete all 6 files systematically

---
