# 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(`
|
||||
⚠️ Hotfix follow-up tasks generated:
|
||||
- Comprehensive fix: ${follow_up_tasks[0].id} (due in 3 days)
|
||||
- Postmortem: ${follow_up_tasks[1].id} (due in 1 week)
|
||||
`)
|
||||
}
|
||||
```
|
||||
|
||||
**TodoWrite**: Mark Phase 6 completed

## 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
|
||||
```
|
||||

## 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
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
## 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)
|
||||
- ✅ Single optional flag (67% reduction)
|
||||
- ✅ Incident info can be in bug description
|
||||
- ✅ Matches lite-plan simplicity
|
||||

|
||||
|
||||
## 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.

**v1.0 User Flow**:
|
||||
```
|
||||
User: "Is this bug Regular or Critical? Not sure..."
|
||||
User: "Let me read the mode descriptions again..."
|
||||
User: "OK I'll try --critical"
|
||||
System: "Executing critical mode..." (might be wrong choice)
|
||||
```
|
||||
|
||||
**v2.0 User Flow**:
|
||||
```
|

System: "Adapting workflow: Focused diagnosis, Smoke+critical tests"
|
||||
User: "Perfect, proceed" (no mode selection needed)
|
||||
```

## 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)

|
||||
| **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.
