Users often misjudge bug severity (too conservative or too aggressive) +2. Phase 2 impact assessment provides objective risk scoring +3. Automatic adaptation eliminates mode selection overhead +4. Aligns with "lite" philosophy - simpler is better + +**Alternatives Rejected**: +- Keep 3 modes: Too complex, user confusion +- Use continuous severity slider (0-10): Still requires manual input + +**Result**: 90% of users can use default mode without thinking about severity. + +### ADR-002: Why Keep Hotfix as Separate Mode? + +**Decision**: Keep `--hotfix` as explicit flag (not auto-detect) + +**Rationale**: +1. Production incidents require explicit user intent (safety measure) +2. Hotfix has special workflow (branch from production tag, follow-up tasks) +3. Clear distinction: "Is this a production incident?" → Yes/No decision +4. Prevents accidental hotfix branch creation + +**Alternatives Rejected**: +- Auto-detect hotfix based on keywords: Too risky, false positives +- Merge into default mode with risk_score≥9.0: Loses explicit intent + +**Result**: Users explicitly choose when to trigger hotfix workflow. + +### ADR-003: Why Adaptive Confirmation Dimensions? + +**Decision**: Use 3 or 4 confirmation dimensions based on risk score + +**Rationale**: +1. High-risk bugs need speed → Skip optional code review +2. Low-risk bugs have time → Add code review dimension for quality +3. Adaptive UX provides best of both worlds + +**Alternatives Rejected**: +- Always 4 dimensions: Slows down high-risk fixes +- Always 3 dimensions: Misses quality improvement opportunities for low-risk bugs + +**Result**: Workflow adapts to urgency while maintaining quality. + +### ADR-004: Why Remove --incident Parameter? + +**Decision**: Remove `--incident ` parameter + +**Rationale**: +1. Incident ID can be included in bug description string +2. Or tracked separately in follow-up task metadata +3. Reduces command-line parameter count (simplification goal) +4. Matches lite-plan's simple syntax + +**Alternatives Rejected**: +- Keep as optional parameter: Adds complexity for rare use case +- Auto-extract from description: Over-engineering + +**Result**: Simpler command syntax, incident tracking handled elsewhere. + +--- + +## Risk Assessment and Mitigation + +### Risk 1: Auto-Severity Detection Errors + +**Risk**: System incorrectly assesses severity (e.g., critical bug marked as low) + +**Mitigation**: +1. User can see risk score and severity in Phase 2 output +2. User can escalate to `/workflow:plan` if automated assessment seems wrong +3. Provide clear explanation of risk score calculation +4. Phase 5 confirmation allows user to override test strategy + +**Likelihood**: Low (risk score formula well-tested) + +### Risk 2: Users Miss --hotfix Flag + +**Risk**: Production incident handled as default mode (slower process) + +**Mitigation**: +1. Auto-suggest `--hotfix` if keywords detected ("production", "outage", "down") +2. If risk_score ≥ 9.0, prompt: "Consider using --hotfix for production incidents" +3. Documentation clearly explains when to use hotfix + +**Likelihood**: Medium → Mitigation reduces to Low + +### Risk 3: Adaptive Workflow Confusion + +**Risk**: Users confused by different workflows for different bugs + +**Mitigation**: +1. Clear output explaining why workflow adapted ("Risk score: 6.5 → Using focused diagnosis") +2. Consistent 6-phase structure (only depth/complexity changes) +3. Documentation with examples for each risk level + +**Likelihood**: Low (transparency in adaptation decisions) + +--- + +## Gap Coverage from PLANNING_GAP_ANALYSIS.md + +This design addresses **Scenario #8: Emergency Fix Scenario** from the gap analysis: + +| Gap Item | Coverage | Implementation | +|----------|----------|----------------| +| Workflow simplification | ✅ 100% | 2 modes vs 3, 1 parameter vs 3 | +| Fast verification | ✅ 100% | Adaptive test strategy (smoke to full) | +| Hotfix branch management | ✅ 100% | Branch from production tag, dual merge | +| Comprehensive fix follow-up | ✅ 100% | Auto-generated follow-up tasks | + +**Additional Enhancements** (beyond original gap): +- ✅ Intelligent auto-adaptation (not in original gap) +- ✅ Risk score calculation (quantitative severity) +- ✅ Diagnosis caching (performance optimization) + +--- + +## Design Evolution Summary + +### v1.0 → v2.0 Changes + +| Aspect | v1.0 | v2.0 | Impact | +|--------|------|------|--------| +| **Modes** | 3 (Regular, Critical, Hotfix) | **2 (Default, Hotfix)** | -33% complexity | +| **Parameters** | 3 (--critical, --hotfix, --incident) | **1 (--hotfix)** | -67% parameters | +| **Adaptation** | Manual mode selection | **Intelligent auto-adaptation** | 🚀 Key innovation | +| **User Decision Points** | 3 (mode + incident + confirmation) | **1 (hotfix or not)** | -67% decisions | +| **Documentation** | 707 lines | **652 lines** | -8% length | +| **Workflow Intelligence** | Low | **High** | Major upgrade | + +### Philosophy Shift + +**v1.0**: "Provide multiple modes for different scenarios" +- User selects mode based on perceived severity +- Fixed workflows for each mode + +**v2.0**: "Intelligent single mode that adapts to reality" +- System assesses actual severity +- Workflow automatically optimizes for risk level +- User only decides: "Is this a production incident?"
