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

/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

Detailed Phase Execution

Phase 1: Diagnosis & Root Cause Analysis

Goal: Identify root cause and affected code paths

Session Folder Setup:

// Generate session identifiers for artifact storage
const bugSlug = bug_description.toLowerCase().replace(/[^a-z0-9]+/g, '-').substring(0, 40)
const timestamp = new Date().toISOString().replace(/[:.]/g, '-')
const shortTimestamp = timestamp.substring(0, 19).replace('T', '-') // YYYY-MM-DD-HH-mm-ss
const sessionId = `${bugSlug}-${shortTimestamp}`
const sessionFolder = `.workflow/.lite-fix/${sessionId}`

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)

// 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:

Read(suspected_file)  # User typically knows the file
git blame ${suspected_file}

Output Structure:

diagnosisContext = {
  symptom: string,
  error_message: string | null,
  keywords: string[],
  confidence_level: "high" | "medium" | "low",
  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"
  }
}

// Save diagnosis results for CLI/agent access in lite-execute
const diagnosisFile = `${sessionFolder}/diagnosis.json`
Write(diagnosisFile, JSON.stringify(diagnosisContext, null, 2))

Output: diagnosisContext (in-memory) Artifact: Saved to {sessionFolder}/diagnosis.json for CLI/agent use

Phase 2: Impact Assessment & Severity Auto-Detection

Goal: Quantify blast radius and auto-determine severity

Risk Score Calculation:

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:

impactContext = {
  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"
  }
}

// Save impact assessment for CLI/agent access
const impactFile = `${sessionFolder}/impact.json`
Write(impactFile, JSON.stringify(impactContext, null, 2))

Output: impactContext (in-memory) Artifact: Saved to {sessionFolder}/impact.json for CLI/agent use

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

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:

// 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:

if (complexity === "high" && risk_score < 5.0) {
  suggestCommand("/workflow:plan --mode bugfix")
  return  // Escalate to full planning
}

// Save fix plan for CLI/agent access
const planFile = `${sessionFolder}/fix-plan.json`
Write(planFile, JSON.stringify(fixPlan, null, 2))

Output: fixPlan (in-memory) Artifact: Saved to {sessionFolder}/fix-plan.json for CLI/agent use

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:

{
  type: "feature_branch",
  base: "main",
  name: "fix/token-expiration-edge-case",
  merge_target: "main"
}

Hotfix Mode:

{
  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):

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):

[
  {
    question: "Confirm hotfix deployment:",
    options: ["Deploy", "Stage First", "Abort"]
  },
  {
    question: "Post-deployment monitoring:",
    options: ["Real-time (15 min)", "Passive (alerts only)"]
  }
]

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):

# 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):

# ✅ 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

---

Session Folder Structure

Each lite-fix execution creates a dedicated session folder to organize all artifacts:

.workflow/.lite-fix/{bug-slug}-{short-timestamp}/
├── diagnosis.json    # Phase 1: Root cause analysis
├── impact.json       # Phase 2: Impact assessment
├── fix-plan.json     # Phase 3: Fix strategy
├── task.json         # Phase 6: Enhanced Task JSON
└── followup.json     # Hotfix mode only: Follow-up tasks

Folder Naming Convention:

• {bug-slug}: First 40 characters of bug description, lowercased, non-alphanumeric replaced with -
• {short-timestamp}: YYYY-MM-DD-HH-mm-ss format
• Example: .workflow/.lite-fix/user-avatar-upload-fails-413-2025-01-15-14-30-45/

File Contents:

• diagnosis.json: Complete diagnosisContext object (Phase 1)
• impact.json: Complete impactContext object (Phase 2)
• fix-plan.json: Complete fixPlan object (Phase 3)
• task.json: Enhanced Task JSON with all context (Phase 6)
• followup.json: Follow-up tasks (hotfix mode only)

Access Patterns:

• lite-fix: Creates folder and writes all artifacts during execution, passes paths via executionContext.session.artifacts
• lite-execute: Reads artifact paths from executionContext.session.artifacts
• User: Can inspect artifacts for debugging or reference
• Reuse: Pass task.json path to /workflow:lite-execute {path} for re-execution

Legacy Cache (deprecated, use session folder instead):

.workflow/.lite-fix-cache/
└── diagnosis-cache/
    └── ${bug_hash}.json

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
