Single-Session Engineering Productivity Audit

Purpose

Evaluates developer experience (DX), debugging capabilities, and offline support infrastructure. Identifies friction points in development workflows and provides actionable recommendations for improvement.

Execution Mode Selection

Section A: Parallel Architecture (3 Agents)

When to use: Task tool available, sufficient context budget

Step 0: Load False Positives

# Read false positives to avoid re-flagging known issues
cat docs/technical-debt/FALSE_POSITIVES.jsonl 2>/dev/null

Agent 1: dx-golden-path-auditor

Focus Areas:

• Developer onboarding friction
• npm scripts completeness
• Setup automation (doctor scripts, env validation)
• Development workflow ergonomics

Files:

• package.json (scripts section)
• scripts/ directory
• .env.example, .env.local
• README.md, DEVELOPMENT.md

Checks:

# Count npm scripts
grep -c '"[^"]*":' package.json

# Check for setup/doctor scripts
ls scripts/*.js 2>/dev/null | grep -E 'setup|doctor|verify'

# Check for dev:offline script
grep -c "dev:offline" package.json

Agent 2: debugging-ergonomics-auditor

Focus Areas:

• Structured logging vs console.log ratio
• Correlation ID support for request tracing
• Error message quality and user guidance
• Sentry integration completeness

Files:

• lib/logger.ts
• *.ts *.tsx files (console.log patterns)
• functions/src/**/*.ts (Cloud Functions logging)
• app/**/error.tsx (error boundaries)

Checks:

# Console.log to logger ratio
echo "Console.log calls:"
grep -r "console.log" --include="*.ts" --include="*.tsx" app/ lib/ components/ | wc -l
echo "Logger calls:"
grep -r "logger\." --include="*.ts" --include="*.tsx" app/ lib/ components/ | wc -l

# Correlation ID patterns
grep -r "correlationId\|correlation-id\|x-request-id" --include="*.ts" .

Agent 3: offline-support-auditor

Focus Areas:

• Firebase IndexedDB persistence configuration
• Service worker presence and functionality
• Offline write queue implementation
• Network status indicators and user feedback

Files:

• lib/firebase.ts
• public/sw.js (if exists)
• components/status/offline-indicator.tsx
• lib/offline-queue.ts (if exists)

Checks:

# Firebase persistence
grep -r "enableIndexedDbPersistence\|enablePersistence" lib/ app/

# Service worker
ls -la public/sw.js 2>/dev/null || echo "No service worker"

# LocalStorage vs IndexedDB usage
grep -r "localStorage" --include="*.ts" --include="*.tsx" | wc -l
grep -r "indexedDB\|IDB\|Dexie" --include="*.ts" --include="*.tsx" | wc -l

Parallel Execution Command

Invoke all 3 agents in a SINGLE Task message:

Task 1: dx-golden-path-auditor agent - audit setup, scripts, onboarding Task 2:
debugging-ergonomics-auditor agent - audit logging, error handling Task 3:
offline-support-auditor agent - audit persistence, service workers

Each agent prompt MUST end with:

CRITICAL RETURN PROTOCOL:

- Write findings to the specified output file using Write tool or Bash
- Return ONLY: `COMPLETE: [agent-id] wrote N findings to [output-path]`
- Do NOT return full findings content — orchestrator checks completion via file

Dependency constraints: All 3 agents are independent -- no ordering required. Each audits a separate domain and writes to separate output sections.

Section B: Sequential Fallback

When to use: Task tool unavailable, context pressure, or user request

Step 1: Golden Path & DX (10 min)

1. Review package.json scripts section
2. Check for setup/doctor automation scripts
3. Verify .env.example completeness
4. Assess README setup instructions
5. Identify missing "golden path" scripts

Step 2: Debugging Ergonomics (10 min)

1. Calculate console.log vs logger ratio
2. Search for correlation ID patterns
3. Review error boundary implementations
4. Check Sentry integration in logger
5. Assess error message quality

Step 3: Offline Support (10 min)

1. Check Firebase persistence configuration
2. Look for service worker implementation
3. Review offline indicator component
4. Search for write queue patterns
5. Assess localStorage vs IndexedDB usage

  --source "audit-engineering-productivity-$(date +%Y-%m-%d)"

When to Use

• User explicitly invokes /audit-engineering-productivity
• Engineering productivity or DX audit is needed
• Called as part of /audit-comprehensive (Stage 2)

When NOT to Use

• When you only need to audit code quality — use /audit-code instead
• When you need CI/CD pipeline health — use /audit-process instead
• When you need a comprehensive multi-domain audit — use /audit-comprehensive

Related Skills

• /audit-comprehensive - Run all 7 domain audits
• /audit-process - CI/CD and automation audit (overlaps with DX)
• /audit-code - Code quality audit
