+# Workflow Lite-Fix Command (/workflow:lite-fix)
+
+## Overview
+
+Fast-track bug fixing workflow optimized for quick diagnosis, targeted fixes, and streamlined verification. Automatically adjusts process complexity based on impact assessment.
+
+**Core capabilities:**
+- Rapid root cause diagnosis with intelligent code search
+- Automatic severity assessment and adaptive workflow
+- Fix strategy selection (immediate patch vs comprehensive refactor)
+- Risk-aware verification (smoke tests to full suite)
+- Optional hotfix mode for production incidents with branch management
+- Automatic follow-up task generation for hotfixes
+
+## Usage
+
+### Command Syntax
+```bash
+/workflow:lite-fix [FLAGS] <BUG_DESCRIPTION>
+
+# Flags
+--hotfix, -h               Production hotfix mode (creates hotfix branch, auto follow-up)
+
+# Arguments
+<bug-description>          Bug description or issue reference (required)
+```
+
+### Modes
+
+| Mode | Time Budget | Use Case | Workflow Characteristics |
+|------|-------------|----------|--------------------------|
+| **Default** | Auto-adapt (15min-4h) | All standard bugs | Intelligent severity assessment + adaptive process |
+| **Hotfix** (`--hotfix`) | 15-30 min | Production outage | Minimal diagnosis + hotfix branch + auto follow-up |
+
+### Examples
+
+```bash
+# Default mode: Automatically adjusts based on impact
+/workflow:lite-fix "User avatar upload fails with 413 error"
+/workflow:lite-fix "Shopping cart randomly loses items at checkout"
+
+# Hotfix mode: Production incident
+/workflow:lite-fix --hotfix "Payment gateway 5xx errors"
+```
+
+## Execution Process
+
+### Workflow Overview
+
+```
+Bug Input → Diagnosis (Phase 1) → Impact Assessment (Phase 2)
+        ↓
+    Severity Auto-Detection → Fix Planning (Phase 3)
+        ↓
+    Verification Strategy (Phase 4) → User Confirmation (Phase 5) → Execution (Phase 6)
+```
+
+### Phase Summary
+
+| Phase | Default Mode | Hotfix Mode |
+|-------|--------------|-------------|
+| 1. Diagnosis | Adaptive search depth | Minimal (known issue) |
+| 2. Impact Assessment | Full risk scoring | Critical path only |
+| 3. Fix Planning | Strategy options based on complexity | Single surgical fix |
+| 4. Verification | Test level matches risk score | Smoke tests only |
+| 5. User Confirmation | 3 dimensions | 2 dimensions |
+| 6. Execution | Via lite-execute | Via lite-execute + monitoring |
+
+---
+
+## Detailed Phase Execution
+
+### Phase 1: Diagnosis & Root Cause Analysis
+
+**Goal**: Identify root cause and affected code paths
+
+**Execution Strategy**:
+
+**Default Mode** - Adaptive search:
+- **High confidence keywords** (e.g., specific error messages): Direct grep search (5min)
+- **Medium confidence**: cli-explore-agent with focused search (10-15min)
+- **Low confidence** (vague symptoms): cli-explore-agent with broad search (20min)
+
+```javascript
+// Confidence-based strategy selection
+if (has_specific_error_message || has_file_path_hint) {
+  // Quick targeted search
+  grep -r '${error_message}' src/ --include='*.ts' -n | head -10
+  git log --oneline --since='1 week ago' -- '*affected*'
+} else {
+  // Deep exploration
+  Task(subagent_type="cli-explore-agent", prompt=`
+    Bug: ${bug_description}
+    Execute diagnostic search:
+    1. Search error patterns and similar issues
+    2. Trace execution path in affected modules
+    3. Check recent changes
+    Return: Root cause hypothesis, affected paths, reproduction steps
+  `)
+}
+```
+
+**Hotfix Mode** - Minimal search:
+```bash
+Read(suspected_file)  # User typically knows the file
+git blame ${suspected_file}
+```
+
+**Output Structure**:
+```javascript
+{
+  root_cause: {
+    file: "src/auth/tokenValidator.ts",
+    line_range: "45-52",
+    issue: "Token expiration check uses wrong comparison",
+    introduced_by: "commit abc123"
+  },
+  reproduction_steps: ["Login", "Wait 15min", "Access protected route"],
+  affected_scope: {
+    users: "All authenticated users",
+    features: ["login", "API access"],
+    data_risk: "none"
+  }
+}
+```
+
+**TodoWrite**: Mark Phase 1 completed, Phase 2 in_progress
+
+---
+
+### Phase 2: Impact Assessment & Severity Auto-Detection
+
+**Goal**: Quantify blast radius and auto-determine severity
+
+**Risk Score Calculation**:
+```javascript
+risk_score = (user_impact × 0.4) + (system_risk × 0.3) + (business_impact × 0.3)
+
+// Auto-severity mapping
+if (risk_score >= 8.0) severity = "critical"
+else if (risk_score >= 5.0) severity = "high"
+else if (risk_score >= 3.0) severity = "medium"
+else severity = "low"
+
+// Workflow adaptation
+if (severity >= "high") {
+  diagnosis_depth = "focused"
+  test_strategy = "smoke_and_critical"
+  review_optional = true
+} else {
+  diagnosis_depth = "comprehensive"
+  test_strategy = "full_suite"
+  review_optional = false
+}
+```
+
+**Assessment Output**:
+```javascript
+{
+  affected_users: {
+    count: "5000 active users (100%)",
+    severity: "high"
+  },
+  system_risk: {
+    availability: "degraded_30%",
+    cascading_failures: "possible_logout_storm"
+  },
+  business_impact: {
+    revenue: "medium",
+    reputation: "high",
+    sla_breach: "yes"
+  },
+  risk_score: 7.1,
+  severity: "high",
+  workflow_adaptation: {
+    test_strategy: "focused_integration",
+    review_required: false,
+    time_budget: "1_hour"
+  }
+}
+```
+
+**Hotfix Mode**: Skip detailed assessment, assume critical
+
+**TodoWrite**: Mark Phase 2 completed, Phase 3 in_progress
+
+---
+
+### Phase 3: Fix Planning & Strategy Selection
+
+**Goal**: Generate fix options with trade-off analysis
+
+**Strategy Generation**:
+
+**Default Mode** - Complexity-adaptive:
+- **Low risk score (<5.0)**: Generate 2-3 strategy options for user selection
+- **High risk score (≥5.0)**: Generate single best strategy for speed
+
+```javascript
+strategies = generateFixStrategies(root_cause, risk_score)
+
+if (risk_score >= 5.0 || mode === "hotfix") {
+  // Single best strategy
+  return strategies[0]  // Fastest viable fix
+} else {
+  // Multiple options with trade-offs
+  return strategies  // Let user choose
+}
+```
+
+**Example Strategies**:
+```javascript
+// Low risk: Multiple options
+[
+  {
+    strategy: "immediate_patch",
+    description: "Fix comparison operator",
+    estimated_time: "15 minutes",
+    risk: "low",
+    pros: ["Quick fix"],
+    cons: ["Doesn't address underlying issue"]
+  },
+  {
+    strategy: "comprehensive_fix",
+    description: "Refactor token validation logic",
+    estimated_time: "2 hours",
+    risk: "medium",
+    pros: ["Addresses root cause"],
+    cons: ["Longer implementation"]
+  }
+]
+
+// High risk or hotfix: Single option
+{
+  strategy: "surgical_fix",
+  description: "Minimal change to fix comparison",
+  files: ["src/auth/tokenValidator.ts:47"],
+  estimated_time: "5 minutes",
+  risk: "minimal"
+}
+```
+
+**Complexity Assessment**:
+```javascript
+if (complexity === "high" && risk_score < 5.0) {
+  suggestCommand("/workflow:plan --mode bugfix")
+  return  // Escalate to full planning
+}
+```
+
+**TodoWrite**: Mark Phase 3 completed, Phase 4 in_progress
+
+---
+
+### Phase 4: Verification Strategy
+
+**Goal**: Define testing approach based on severity
+
+**Adaptive Test Strategy**:
+
+| Risk Score | Test Scope | Duration | Automation |
+|------------|------------|----------|------------|
+| **< 3.0** (Low) | Full test suite | 15-20 min | `npm test` |
+| **3.0-5.0** (Medium) | Focused integration | 8-12 min | `npm test -- affected-module.test.ts` |
+| **5.0-8.0** (High) | Smoke + critical | 5-8 min | `npm test -- critical.smoke.test.ts` |
+| **≥ 8.0** (Critical) | Smoke only | 2-5 min | `npm test -- smoke.test.ts` |
+| **Hotfix** | Production smoke | 2-3 min | `npm test -- production.smoke.test.ts` |
+
+**Branch Strategy**:
+
+**Default Mode**:
+```javascript
+{
+  type: "feature_branch",
+  base: "main",
+  name: "fix/token-expiration-edge-case",
+  merge_target: "main"
+}
+```
+
+**Hotfix Mode**:
+```javascript
+{
+  type: "hotfix_branch",
+  base: "production_tag_v2.3.1",  // ⚠️ From production tag
+  name: "hotfix/token-validation-fix",
+  merge_target: ["main", "production"]  // Dual merge
+}
+```
+
+**TodoWrite**: Mark Phase 4 completed, Phase 5 in_progress
+
+---
+
+### Phase 5: User Confirmation & Execution Selection
+
+**Adaptive Confirmation Dimensions**:
+
+**Default Mode** - 3 dimensions (adapted by risk score):
+
+```javascript
+dimensions = [
+  {
+    question: "Confirm fix approach?",
+    options: ["Proceed", "Modify", "Escalate to /workflow:plan"]
+  },
+  {
+    question: "Execution method:",
+    options: ["Agent", "CLI Tool (Codex/Gemini)", "Manual (plan only)"]
+  },
+  {
+    question: "Verification level:",
+    options: adaptedByRiskScore()  // Auto-suggest based on Phase 2
+  }
+]
+
+// If risk_score >= 5.0, auto-skip code review dimension
+// If risk_score < 5.0, add optional code review dimension
+if (risk_score < 5.0) {
+  dimensions.push({
+    question: "Post-fix review:",
+    options: ["Gemini", "Skip"]
+  })
+}
+```
+
+**Hotfix Mode** - 2 dimensions (minimal):
+```javascript
+[
+  {
+    question: "Confirm hotfix deployment:",
+    options: ["Deploy", "Stage First", "Abort"]
+  },
+  {
+    question: "Post-deployment monitoring:",
+    options: ["Real-time (15 min)", "Passive (alerts only)"]
+  }
+]
+```
+
+**TodoWrite**: Mark Phase 5 completed, Phase 6 in_progress
+
+---
+
+### Phase 6: Execution Dispatch & Follow-up
+
+**Dispatch to lite-execute**:
+
+```javascript
+executionContext = {
+  mode: "bugfix",
+  severity: auto_detected_severity,  // From Phase 2
+  planObject: plan,
+  diagnosisContext: diagnosis,
+  impactContext: impact_assessment,
+  verificationStrategy: test_strategy,
+  branchStrategy: branch_strategy,
+  executionMethod: user_selection.execution_method
+}
+
+SlashCommand("/workflow:lite-execute --in-memory --mode bugfix")
+```
+
+**Hotfix Auto Follow-up**:
+
+```javascript
+if (mode === "hotfix") {
+  follow_up_tasks = [
+    {
+      id: `FOLLOWUP-${taskId}-comprehensive`,
+      title: "Replace hotfix with comprehensive fix",

+
+## Best Practices
+
+### When to Use Default Mode
+
+**Use for all standard bugs:**
+- Automatically adapts to severity (no manual mode selection needed)
+- Risk score determines workflow complexity
+- Handles 90% of bug fixing scenarios
+
+**Typical scenarios:**
+- UI bugs, logic errors, edge cases
+- Performance issues (non-critical)
+- Integration failures
+- Data validation bugs
+
+### When to Use Hotfix Mode
+
+**Only use for production incidents:**
+- Production is down or critically degraded
+- Revenue/reputation at immediate risk
+- SLA breach occurring
+- Issue is well-understood (minimal diagnosis needed)
+
+**Hotfix characteristics:**
+- Creates hotfix branch from production tag
+- Minimal diagnosis (assumes known issue)
+- Smoke tests only
+- Auto-generates follow-up tasks
+- Requires incident tracking
+
+### Branching Strategy
+
+**Default Mode (feature branch)**:
+```bash
+# Standard feature branch workflow
+git checkout -b fix/issue-description main
+# ... implement fix
+git checkout main && git merge fix/issue-description
+```
+
+**Hotfix Mode (dual merge)**:
+```bash
+# ✅ Correct: Branch from production tag
+git checkout -b hotfix/fix-name v2.3.1
+
+# Merge to both targets
+git checkout main && git merge hotfix/fix-name
+git checkout production && git merge hotfix/fix-name
+git tag v2.3.2
+
+# ❌ Wrong: Branch from main
+git checkout -b hotfix/fix-name main  # Contains unreleased code!
+```
+
+---
+
+## Error Handling
+
+| Error | Cause | Resolution |
+|-------|-------|------------|
+| Root cause unclear | Vague symptoms | Extend diagnosis time or use /cli:mode:bug-diagnosis |
+| Multiple potential causes | Complex interaction | Use /cli:discuss-plan for analysis |
+| Fix too complex | High-risk refactor | Escalate to /workflow:plan --mode bugfix |
+| High risk score but unsure | Uncertain severity | Default mode will adapt, proceed normally |
+
+---
+
+## Output Routing
+
+**Lite-fix directory**:
+```
+.workflow/lite-fixes/
+├── BUGFIX-2024-10-20T14-30-00.json          # Task JSON
+├── BUGFIX-2024-10-20T14-30-00-followup.json # Follow-up (hotfix only)
+└── diagnosis-cache/                          # Cached diagnoses
+    └── ${bug_hash}.json
+```
+
+**Session-based** (if active session):
+```
+.workflow/active/WFS-feature/
+├── .bugfixes/
+│   ├── BUGFIX-001.json
+│   └── BUGFIX-001-followup.json
+└── .summaries/
+    └── BUGFIX-001-summary.md
+```
+
+---
+
+## Advanced Features
+
+### 1. Intelligent Diagnosis Caching
+
+Reuse diagnosis for similar bugs:
+```javascript
+cache_key = hash(bug_keywords + recent_changes_hash)
+if (cache_exists && cache_age < 7_days && similarity > 0.8) {
+  diagnosis = load_from_cache()
+  console.log("Using cached diagnosis (similar issue found)")
+}
+```
+
+### 2. Auto-Severity Suggestion
+
+Detect urgency from keywords:
+```javascript
+urgency_keywords = ["production", "down", "outage", "critical", "urgent"]
+if (bug_description.includes(urgency_keywords) && !mode_specified) {
+  console.log("💡 Tip: Consider --hotfix flag for production issues")
+}
+```
+
+### 3. Adaptive Workflow Intelligence
+
+Real-time workflow adjustment:
+```javascript
+// During Phase 2, if risk score suddenly increases
+if (new_risk_score > initial_estimate * 1.5) {
+  console.log("⚠️ Severity increased, adjusting workflow...")
+  test_strategy = "more_comprehensive"
+  review_required = true
+}
+```
+
+---
+
+## Related Commands
+
+**Diagnostic Commands**:
+- `/cli:mode:bug-diagnosis` - Detailed root cause analysis (use before lite-fix if unclear)
+
+**Fix Execution**:
+- `/workflow:lite-execute --in-memory` - Execute fix plan (automatically called)
+
+**Planning Commands**:
+- `/workflow:plan --mode bugfix` - Complex bugs requiring comprehensive planning
+
+**Review Commands**:
+- `/workflow:review --type quality` - Post-fix quality review
+
+---
+
+## Comparison with Other Commands
+
+| Command | Use Case | Modes | Adaptation | Output |
+|---------|----------|-------|------------|--------|
+| `/workflow:lite-fix` | Bug fixes | 2 (default + hotfix) | Auto-adaptive | In-memory + JSON |
+| `/workflow:lite-plan` | New features | 1 + explore flag | Manual | In-memory + JSON |
+| `/workflow:plan` | Complex features | Multiple | Manual | Persistent session |
+| `/cli:mode:bug-diagnosis` | Analysis only | 1 | N/A | Report only |
+
+---
+
+## Quality Gates
+
+**Before execution** (auto-checked):
+- [ ] Root cause identified (>70% confidence for default, >90% for hotfix)
+- [ ] Impact scope defined
+- [ ] Fix strategy reviewed
+- [ ] Verification plan matches risk level
+
+**Hotfix-specific**:
+- [ ] Production tag identified
+- [ ] Rollback plan documented
+- [ ] Follow-up tasks generated
+- [ ] Monitoring configured
+
+---
+
+## When to Use lite-fix
+
+✅ **Perfect for:**
+- Any bug with clear symptoms
+- Localized fixes (1-5 files)
+- Known technology stack
+- Time-sensitive but not catastrophic (default mode adapts)
+- Production incidents (use --hotfix)
+
+❌ **Not suitable for:**
+- Root cause completely unclear → use `/cli:mode:bug-diagnosis` first
+- Requires architectural changes → use `/workflow:plan`
+- Complex legacy code without tests → use `/workflow:plan --legacy-refactor`
+- Performance deep-dive → use `/workflow:plan --performance-optimization`
+- Data migration → use `/workflow:plan --data-migration`

+# Lite-Fix Command Design Document
+
+**Date**: 2025-11-20
+**Version**: 2.0.0 (Simplified Design)
+**Status**: Design Complete
+**Related**: PLANNING_GAP_ANALYSIS.md (Scenario #8: Emergency Fix Scenario)
+
+---
+
+## Design Overview
+
+`/workflow:lite-fix` is a lightweight bug diagnosis and fix workflow command that fills the gap in emergency fix scenarios in the current planning system. Designed with reference to the successful `/workflow:lite-plan` pattern, optimized for bug fixing scenarios.
+
+### Core Design Principles
+
+1. **Rapid Response** - Supports 15 minutes to 4 hours fix cycles
+2. **Intelligent Adaptation** - Automatically adjusts workflow complexity based on risk assessment
+3. **Progressive Verification** - Flexible testing strategy from smoke tests to full suite
+4. **Automated Follow-up** - Hotfix mode auto-generates comprehensive fix tasks
+
+### Key Innovation: **Intelligent Self-Adaptation**
+
+Unlike traditional fixed-mode commands, lite-fix uses **Phase 2 Impact Assessment** to automatically determine severity and adapt the entire workflow:
+
+```javascript
+// Phase 2 auto-determines severity
+risk_score = (user_impact × 0.4) + (system_risk × 0.3) + (business_impact × 0.3)
+
+// Workflow auto-adapts
+if (risk_score < 3.0)      → Full test suite, comprehensive diagnosis
+else if (risk_score < 5.0) → Focused integration, moderate diagnosis
+else if (risk_score < 8.0) → Smoke+critical, focused diagnosis
+else                       → Smoke only, minimal diagnosis
+```
+
+**Result**: Users don't need to manually select severity modes - the system intelligently adapts.
+
+---
+
+## Design Comparison: lite-fix vs lite-plan
+
+| Dimension | lite-plan | lite-fix (v2.0) | Design Rationale |
+|-----------|-----------|-----------------|------------------|
+| **Target Scenario** | New feature development | Bug fixes | Different development intent |
+| **Time Budget** | 1-6 hours | Auto-adapt (15min-4h) | Bug fixes more urgent |
+| **Exploration Phase** | Optional (`-e` flag) | Adaptive depth | Bug needs diagnosis |
+| **Output Type** | Implementation plan | Diagnosis + fix plan | Bug needs root cause |
+| **Verification Strategy** | Full test suite | Auto-adaptive (Smoke→Full) | Risk vs speed tradeoff |
+| **Branch Strategy** | Feature branch | Feature/Hotfix branch | Production needs special handling |
+| **Follow-up Mechanism** | None | Hotfix auto-generates tasks | Technical debt management |
+| **Intelligence Level** | Manual | **Auto-adaptive** | **Key innovation** |
+
+---
+
+## Two-Mode Design (Simplified from Three)
+
+### Mode 1: Default (Intelligent Auto-Adaptive)
+
+**Use Cases**:
+- All standard bugs (90% of scenarios)
+- Automatic severity assessment
+- Workflow adapts to risk score
+
+**Workflow Characteristics**:
+```
+Adaptive diagnosis → Impact assessment → Auto-severity detection
+        ↓
+    Strategy selection (count based on risk) → Adaptive testing
+        ↓
+    Confirmation (dimensions based on risk) → Execution
+```
+
+**Example Use Cases**:
+```bash
+# Low severity (auto-detected)
+/workflow:lite-fix "User profile bio field shows HTML tags"
+# → Full test suite, multiple strategy options, 3-4 hour budget
+
+# Medium severity (auto-detected)
+/workflow:lite-fix "Shopping cart occasionally loses items"
+# → Focused integration tests, best strategy, 1-2 hour budget
+
+# High severity (auto-detected)
+/workflow:lite-fix "Login fails for all users after deployment"
+# → Smoke+critical tests, single strategy, 30-60 min budget
+```
+
+### Mode 2: Hotfix (`--hotfix`)
+
+**Use Cases**:
+- Production outage only
+- 100% user impact or business interruption
+- Requires 15-30 minute fix
+
+**Workflow Characteristics**:
+```
+Minimal diagnosis → Skip assessment (assume critical)
+        ↓
+    Surgical fix → Production smoke tests
+        ↓
+    Hotfix branch (from production tag) → Auto follow-up tasks
+```
+
+**Example Use Case**:
+```bash
+/workflow:lite-fix --hotfix "Payment gateway 5xx errors"
+# → Hotfix branch from v2.3.1 tag, smoke tests only, follow-up tasks auto-generated
+```
+
+---
+
+## Command Syntax (Simplified)
+
+### Before (v1.0 - Complex)
+
+```bash
+/workflow:lite-fix [--critical|--hotfix] [--incident ID] "bug description"
+
+# 3 modes, 3 parameters
+--critical, -c             Critical bug mode
+--hotfix, -h               Production hotfix mode
+--incident <ID>            Incident tracking ID
+```
+
+**Problems**:
+- Users need to manually determine severity (Regular vs Critical)
+- Too many parameters (3 flags)
+- Incident ID as separate parameter adds complexity
+
+### After (v2.0 - Simplified)
+
+```bash
+/workflow:lite-fix [--hotfix] "bug description"
+
+# 2 modes, 1 parameter
+--hotfix, -h               Production hotfix mode only
+```
+
+**Improvements**:
+- ✅ Automatic severity detection (no manual selection)

+
+## Intelligent Adaptive Workflow
+
+### Phase 1: Diagnosis - Adaptive Search Depth
+
+**Confidence-based Strategy Selection**:
+
+```javascript
+// High confidence (specific error message provided)
+if (has_specific_error_message || has_file_path_hint) {
+  strategy = "direct_grep"
+  time_budget = "5 minutes"
+  grep -r '${error_message}' src/ --include='*.ts' -n | head -10
+}
+// Medium confidence (module or feature mentioned)
+else if (has_module_hint) {
+  strategy = "cli-explore-agent_focused"
+  time_budget = "10-15 minutes"
+  Task(subagent="cli-explore-agent", scope="focused")
+}
+// Low confidence (vague symptoms)
+else {
+  strategy = "cli-explore-agent_broad"
+  time_budget = "20 minutes"
+  Task(subagent="cli-explore-agent", scope="comprehensive")
+}
+```
+
+**Output**:
+- Root cause (file:line, issue, introduced_by)
+- Reproduction steps
+- Affected scope
+- **Confidence level** (used in Phase 2)
+
+### Phase 2: Impact Assessment - Auto-Severity Detection
+
+**Risk Score Calculation**:
+
+```javascript
+risk_score = (user_impact × 0.4) + (system_risk × 0.3) + (business_impact × 0.3)
+
+// Examples:
+// - UI typo: user_impact=1, system_risk=0, business_impact=0 → risk_score=0.4 (LOW)
+// - Cart bug: user_impact=5, system_risk=3, business_impact=4 → risk_score=4.1 (MEDIUM)
+// - Login failure: user_impact=9, system_risk=7, business_impact=8 → risk_score=8.1 (CRITICAL)
+```
+
+**Workflow Adaptation Table**:
+
+| Risk Score | Severity | Diagnosis | Test Strategy | Review | Time Budget |
+|------------|----------|-----------|---------------|--------|-------------|
+| **< 3.0** | Low | Comprehensive | Full test suite | Optional | 3-4 hours |
+| **3.0-5.0** | Medium | Moderate | Focused integration | Optional | 1-2 hours |
+| **5.0-8.0** | High | Focused | Smoke + critical | Skip | 30-60 min |
+| **≥ 8.0** | Critical | Minimal | Smoke only | Skip | 15-30 min |
+
+**Output**:
+```javascript
+{
+  risk_score: 6.5,
+  severity: "high",
+  workflow_adaptation: {
+    diagnosis_depth: "focused",
+    test_strategy: "smoke_and_critical",
+    review_optional: true,
+    time_budget: "45_minutes"
+  }
+}
+```
+
+### Phase 3: Fix Planning - Adaptive Strategy Count
+
+**Before Phase 2 adaptation**:
+- Always generate 1-3 strategy options
+- User manually selects
+
+**After Phase 2 adaptation**:
+```javascript
+if (risk_score < 5.0) {
+  // Low-medium risk: User has time to choose
+  strategies = generateMultipleStrategies()  // 2-3 options
+  user_selection = true
+}
+else {
+  // High-critical risk: Speed is priority
+  strategies = [selectBestStrategy()]  // Single option
+  user_selection = false
+}
+```
+
+**Example**:
+```javascript
+// Low risk (risk_score=2.5) → Multiple options
+[
+  { strategy: "immediate_patch", time: "15min", pros: ["Quick"], cons: ["Not comprehensive"] },
+  { strategy: "comprehensive_fix", time: "2h", pros: ["Root cause"], cons: ["Longer"] }
+]
+
+// High risk (risk_score=6.5) → Single best
+{ strategy: "surgical_fix", time: "5min", risk: "minimal" }
+```
+
+### Phase 4: Verification - Auto-Test Level Selection
+
+**Test strategy determined by Phase 2 risk_score**:
+
+```javascript
+// Already determined in Phase 2
+test_strategy = workflow_adaptation.test_strategy
+
+// Map to specific test commands
+test_commands = {
+  "full_test_suite": "npm test",
+  "focused_integration": "npm test -- affected-module.test.ts",
+  "smoke_and_critical": "npm test -- critical.smoke.test.ts",
+  "smoke_only": "npm test -- smoke.test.ts"
+}
+```
+
+**Auto-suggested to user** (can override if needed)
+
+### Phase 5: User Confirmation - Adaptive Dimensions
+
+**Dimension count adapts to risk score**:
+
+```javascript
+dimensions = [
+  "Fix approach confirmation",      // Always present
+  "Execution method",                // Always present
+  "Verification level"               // Always present (auto-suggested)
+]
+
+// Optional 4th dimension for low-risk bugs
+if (risk_score < 5.0) {
+  dimensions.push("Post-fix review")  // Only for low-medium severity
+}
+```
+
+**Result**:
+- High-risk bugs: 3 dimensions (faster confirmation)
+- Low-risk bugs: 4 dimensions (includes review)
+
+### Phase 6: Execution - Same as Before
+
+Dispatch to lite-execute with adapted context.
+
+---
+
+## Six-Phase Execution Flow Design
+
+### Phase Summary Comparison
+
+| Phase | v1.0 (3 modes) | v2.0 (Adaptive) |
+|-------|----------------|-----------------|
+| 1. Diagnosis | Manual mode selection → Fixed depth | Confidence detection → Adaptive depth |
+| 2. Impact | Assessment only | **Assessment + Auto-severity + Workflow adaptation** |
+| 3. Planning | Fixed strategy count | **Risk-based strategy count** |
+| 4. Verification | Manual test selection | **Auto-suggested test level** |
+| 5. Confirmation | Fixed dimensions | **Adaptive dimensions (3 or 4)** |
+| 6. Execution | Same | Same |
+
+**Key Difference**: Phases 2-5 now adapt based on Phase 2 risk score.

+
+## Architecture Decision Records (ADRs)
+
+### ADR-001: Why Remove Critical Mode?
+
+**Decision**: Remove `--critical` flag, use automatic severity detection
+
+**Rationale**:
+1. 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 <ID>` 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)

+
+### 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 |

+| **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?" (Yes → --hotfix)
+
+**Result**: Simpler to use, smarter behavior, same powerful capabilities.
