# 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",
priority: "high",
due_date: "within_3_days",
description: "Refactor quick hotfix into proper solution with full test coverage"
},
{
id: `FOLLOWUP-${taskId}-postmortem`,
title: "Incident postmortem",
priority: "medium",
due_date: "within_1_week",
sections: ["Timeline", "Root cause", "Prevention measures"]
}
]
Write(`.workflow/lite-fixes/${taskId}-followup.json`, follow_up_tasks)
console.log(`

## 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`

**Extraction Script Reference**: `~/.claude/scripts/extract-layout-structure.js`
**Usage**: Read the script file and use content directly in `mcp__chrome-devtools__evaluate_script()`
**Script returns**:
- `metadata`: Extraction timestamp, URL, method, version
- `patterns`: Layout pattern statistics (flexColumn, flexRow, grid counts)
- `structure`: Hierarchical DOM tree with layout properties
- `exploration`: (Optional) Progressive exploration results when standard selectors fail
**Benefits**:
- ✅ Real flex/grid configuration (justifyContent, alignItems, gap, etc.)
- ✅ Accurate element bounds (x, y, width, height)
- ✅ Structural hierarchy with depth control
- ✅ Layout pattern identification (flex-row, flex-column, grid-NCol)
- ✅ Progressive exploration: Auto-discovers missing selectors
**Progressive Exploration Strategy** (v2.2.0+):
When script finds <3 main containers, it automatically:
1. **Scans** all large visible containers (≥500×300px)
2. **Extracts** class patterns matching: `main|content|wrapper|container|page|layout|app`
3. **Suggests** new selectors to add to script
4. **Returns** exploration data in `result.exploration`:
```json
{
"triggered": true,
"discoveredCandidates": [{classes, bounds, display}],
"suggestedSelectors": [".wrapper", ".page-index"],
"recommendation": ".wrapper, .page-index, .app-container"
}
```
**Using Exploration Results**:
```javascript
// After extraction, check for suggestions
IF result.exploration?.triggered:
REPORT: result.exploration.warning
REPORT: "Suggested selectors: " + result.exploration.recommendation
// Update script by adding to commonClassSelectors array
// Then re-run extraction for better coverage
```
**Selector Update Workflow**:
1. Run extraction on unfamiliar site
2. Check `result.exploration.suggestedSelectors`
3. Add relevant selectors to script's `commonClassSelectors`
4. Re-run extraction → improved container detection

**Extraction Script Reference**: `~/.claude/scripts/extract-computed-styles.js`
**Usage**: Read the script file and use content directly in `mcp__chrome-devtools__evaluate_script()`
**Script returns**:
- `metadata`: Extraction timestamp, URL, method
- `tokens`: Organized design tokens (colors, borderRadii, shadows, fontSizes, fontWeights, spacing)
**Benefits**:
- ✅ Pixel-perfect accuracy for border-radius, box-shadow, padding, etc.
- ✅ Eliminates guessing from visual analysis
- ✅ Provides ground truth for design tokens

**Goal:** Create a design system and prototypes based on existing reference sites.
**Goal:** Create a design system and prototypes based on existing local references.
**Primary Command:** `imitate-auto`
**Steps:**
1. **Initiate**: User runs `/workflow:ui-design:imitate-auto --url-map "home:https://example.com, pricing:https://example.com/pricing"`
2. **Capture**: System screenshots all provided URLs.
3. **Extraction**: System extracts a unified design system (style, layout, animation) from the primary URL.
4. **Assembly**: System recreates all target pages using the extracted system.
1. **Initiate**: User runs `/workflow:ui-design:imitate-auto --input "design-refs/*.png"` with local reference files
2. **Input Detection**: System detects input type (images, code files, or text)
3. **Extraction**: System extracts a unified design system (style, layout, animation) from the references.
4. **Assembly**: System creates prototypes using the extracted system.
**Example:**
```bash
# Using reference images
/workflow:ui-design:imitate-auto \
--url-map "landing:https://stripe.com, pricing:https://stripe.com/pricing, docs:https://stripe.com/docs" \
--capture-mode batch \

--session WFS-002
# Or importing from existing code
/workflow:ui-design:imitate-auto \
--input "./src/components" \
--session WFS-002
```
**Output:**
- Screenshots of all URLs
- `design-tokens.json` (unified style system)
- `layout-templates.json` (page structures)
- 3 HTML prototypes matching the captured pages
