+## 🎯 Key Finding: 95%+ Code Duplication
+
+Three agent files contain nearly identical campaign design instructions:
+
+| File | Lines | Duplication |
+|------|-------|-------------|
+| `.github/agents/create-agentic-campaign.agent.md` | 574 | ~400 duplicate |
+| `.github/agents/agentic-campaign-designer.agent.md` | 286 | ~200 duplicate |
+| `pkg/cli/templates/agentic-campaign-designer.agent.md` | 286 | 100% duplicate |
+
+**Total**: 600 lines of duplication (52% of all agent code)
+
+---
+
+## 💡 Quick Recommendations
+
+### Priority 1: Consolidate Instructions ⭐⭐⭐⭐⭐
+- **Impact**: Eliminate 600 duplicate lines (69% reduction)
+- **Effort**: 4-6 hours
+- **Action**: Create shared instruction document imported by all agents
+
+### Priority 2: Pass Workflow Suggestions ⭐⭐⭐⭐
+- **Impact**: Save 2-3 minutes per campaign
+- **Effort**: 2-3 hours
+- **Action**: Include CCA workflow analysis in issue body
+
+### Priority 3: Create Workflow Catalog ⭐⭐⭐
+- **Impact**: Long-term maintainability
+- **Effort**: 6-8 hours + 15 min per workflow
+- **Action**: Single source of truth for workflow categorization
+

+
+## 📊 Expected Outcomes
+
+| Metric | Before | After | Improvement |
+|--------|--------|-------|-------------|
+| **Code Duplication** | 600 lines | 0 lines | 100% elimination |
+| **Files to Update** | 3 files | 1 file | 67% reduction |
+| **Update Time** | 15-20 min | 3-5 min | 75% faster |
+| **Review Time** | 20-30 min | 5-10 min | 67% faster |
+| **Total Code** | 1,146 lines | 360 lines | 69% reduction |
+| **Drift Risk** | High | Zero | 100% safer |

+## 🚀 Implementation Phases
+
+**Detailed specifications**: See [`campaign-creation-implementation-plan.md`](./campaign-creation-implementation-plan.md)
+
+### Phase 1: Foundation (Week 1)
+- Create workflow catalog (`.github/workflow-catalog.yml`)
+- Create issue form template (`.github/ISSUE_TEMPLATE/new-agentic-campaign.yml`)
+- Implement `update-issue` safe output
+- Update campaign-generator.md with catalog query and spec generation
+- Configure assign-to-agent trigger
+
+**Outcome**: Optimized two-phase architecture with deterministic discovery
+
+### Phase 2: Consolidation (Week 2-3)
+- Create shared instructions (`pkg/campaign/prompts/campaign_creation_instructions.md`)
+- Extract duplicated logic from 3 agent files
+- Update agents to import shared instructions
+- Handle template file (delete or deprecate)
+- Decide on CCA agent (remove or repurpose)
+- Comprehensive testing
+
+**Outcome**: 69% code reduction, zero duplication
+
+### Phase 3: Future Enhancements
+- Dry-run mode for testing
+- Webhook notifications
+- Performance metrics tracking
+- Enhanced workflow catalog with auto-updates
+- Campaign analytics dashboard
+
+**Outcome**: Advanced UX optimizations
+

+
+### Before Starting
+- [ ] Review executive summary with team
+- [ ] Review implementation plan

+- [ ] Assign owner for each phase
+- [ ] Set timeline and milestones
+
+### Phase 1: Foundation (Week 1)

+- [ ] Create `.github/ISSUE_TEMPLATE/new-agentic-campaign.yml`
+- [ ] Implement `update-issue` safe output in `pkg/workflow/safe_outputs.go`
+- [ ] Create `actions/update-issue/action.yml`
+- [ ] Update `campaign-generator.md` with catalog query
+- [ ] Add spec generation logic to generator
+- [ ] Configure assign-to-agent trigger (workflow dispatch)
+- [ ] Test end-to-end flow
+
+### Phase 2: Consolidation (Week 2-3)
+- [ ] Create `pkg/campaign/prompts/` directory
+- [ ] Create `campaign_creation_instructions.md` with shared logic
+- [ ] Extract duplicated logic from CCA agent
+- [ ] Extract duplicated logic from designer agent
+- [ ] Update generator to import shared instructions
+- [ ] Update designer to import shared instructions
+- [ ] Handle template file (delete/deprecate)
+- [ ] Decide on CCA agent (remove/repurpose)
+- [ ] Test consolidated flow
+- [ ] Verify zero code duplication
+- [ ] Update documentation
+
+### Phase 3: Future Enhancements
+- [ ] Implement dry-run mode
+- [ ] Add webhook notifications
+- [ ] Create performance metrics tracking
+- [ ] Add workflow health checks
+- [ ] Implement auto-catalog updates
+
+### After Implementation
+- [ ] Measure code reduction (target: 69%)
+- [ ] Measure execution time (target: 2-3 min)
+- [ ] Measure update time (target: 3-5 min)
+- [ ] Monitor for drift (target: zero incidents)
+- [ ] Update training materials
+- [ ] Share results with team

+
+## 🤔 Frequently Asked Questions
+
+### Q: Will this break existing workflows?
+**A**: No. The consolidation uses existing import mechanisms (`{{#runtime-import?}}`). Fully backward compatible.
+
+### Q: How much work is required?
+**A**: Phase 1 (1 week), Phase 2 (2-3 weeks), Phase 3 (optional, future). Total: 3-4 weeks for full implementation.
+
+### Q: What's the biggest risk?
+**A**: Import mechanism failure. Mitigation: Thorough testing, feature branch, fall back to duplication if needed.
+
+### Q: Can we do this incrementally?
+**A**: Yes. Phase 1 provides immediate value without code changes. Phase 2 can be done gradually (one agent at a time).
+
+### Q: Why not just use GitHub Copilot to sync files?
+**A**: Copilot doesn't prevent drift over time. Single source of truth eliminates the problem, not just the symptom.
+
+### Q: What about the template duplication?
+**A**: Need to investigate how `assign-to-agent` uses templates. Likely install-time copy, which is acceptable.
