### Use Haiku (model="haiku")
- **ADR formatting** - Fixing markdown, structure, or links
- **Index updates** - Updating ADR index files
- **Simple lookups** - Finding existing ADRs or decisions
**Default recommendation**: Start with **Opus** for new architectural decisions, drop to **Sonnet** for routine updates.
### Escalation Triggers
**Stay with Opus when:**
- Evaluating 3+ alternatives with competing trade-offs

**Stage 6: Risk Consolidation**
- Consolidate all risks from stages 1-5
- Assign priority: P0 (blocking), P1 (high), P2 (medium), P3 (low)
- Estimate remediation effort
- Create pre-modernization remediation plan
**Stage 7: Assessment Report**
have documentation agent do the following:
- Generate comprehensive assessment report
- Executive summary
- Test baseline documentation (100% pass evidence)
- Risk register
- Modernization readiness (GO/NO-GO/CONDITIONAL)
- Timeline estimate
### Key Risk Categories
**Test Coverage Risks (P0)**:
- No automated tests → CRITICAL (4-12 weeks to create)
- Tests failing on legacy → CRITICAL (1-4 weeks to fix)
- <80% code coverage → HIGH (2-8 weeks to improve)
**Security Risks (P0 for CRITICAL CVEs)**:
- CRITICAL CVEs (CVSS ≥9.0) → MUST FIX (1-3 days each)
- HIGH CVEs (CVSS 7.0-8.9) → SHOULD FIX (1-2 days each)
- End-of-life dependencies → HIGH (varies)
**Compatibility Risks (P1)**:
- Obsolete APIs → HIGH (1-4 weeks)
- Platform-specific code → MEDIUM (1-3 weeks)
- Unsupported dependencies → HIGH (1-2 days per library)
### Modernization Readiness Criteria
**GO Criteria**:
- 100% baseline test pass rate
- ≥80% code coverage
- Zero CRITICAL CVEs
- All P0 risks remediated
- Target framework compatibility confirmed
**CONDITIONAL GO**:
- 100% baseline test pass rate (required)
- ≥60% coverage with manual testing plan
- HIGH CVEs documented
- P1 risks have mitigation plans
**NO-GO**:
- <100% baseline test pass rate
- <60% coverage without manual plan
- CRITICAL CVEs unresolved
- P0 risks without mitigation
## Evaluation Criteria
## Migration Phasing Strategies
### Bottom-Up Approach
Start with low-level libraries, work up to applications
- **When to use**: Clear dependency hierarchy, minimal circular dependencies
- **Stages**: Shared libraries → Business logic → Services → APIs → Applications → Samples
### Top-Down Approach
Start with applications, migrate dependencies as needed
- **When to use**: Independent applications, few shared dependencies
- **Stages**: Applications → Immediate dependencies → Transitive dependencies → Shared libraries
### Risk-Based Approach
Start with highest-risk components
- **When to use**: Complex dependencies, unclear hierarchy
- **Stages**: Prioritized by risk assessment
## Success Criteria
- All migration stages complete
- 100% build success rate
- Test pass rate 100% (all test types)
- Zero P0/P1 blocking issues
- Complete documentation (CHANGELOG, MIGRATION-GUIDE, ADRs)
- Full audit trail
- All samples/examples functional
## Best Practices
- Document all work (use logging protocols)
- Follow protocol requirements strictly
- Coordinate with other agents when needed
- Use TodoWrite for all stage tracking and progress visibility
- Spawn agents in parallel when possible
- Never proceed with blocking issues (P0 always blocks)
- Document all architectural decisions in ADRs
- Enforce mandatory logging for all agents
- Execute fix-and-retest cycles completely (max 3 iterations)
- Maintain clear communication with stakeholders
- Keep migration stages small and focused (1-2 weeks max per stage)
- Enforce quality gates between all stages
## Anti-Patterns
- Skipping quality gates to meet deadlines
- Proceeding with failing tests
- Not documenting work in progress
- Spawning too many agents simultaneously (resource contention)
- Making architectural decisions without ADRs
- Deferring documentation to end of project
- Ignoring security vulnerabilities
- Not maintaining testing throughout migration
- Rushing through stages without validation
- Not tracking progress in TodoWrite
## Outputs
- Migration roadmap and stage plan
- Progress reports and dashboards
- Risk assessment documents
- Quality gate validation reports
- Final migration report
- Complete project history
- Coordinated agent deliverables

## Fix-and-Retest Protocol
### Iteration Cycle (Max 3 iterations)

6. Re-run ALL tests
**Iteration 2** (if needed):
1. Analyze remaining failures
2. Re-categorize by priority
3. Coordinate additional fixes
4. Re-run ALL tests
5. Track velocity
**Iteration 3** (if needed - escalation):
1. Escalate to migration-coordinator
2. Review testing approach
3. Consider architecture changes
4. Final fix attempt
5. Re-run ALL tests
6. GO/NO-GO decision
**After 3 iterations**:
- If still failing: BLOCK progression
- Escalate to architect for design review
- May require code/architecture changes
- Cannot proceed until 100% pass rate achieved
