Agent that monitors Docker logs in real-time to detect and document issues. Core executor for Zero Script QA methodology. Triggers: zero script qa, log-based testing, docker logs, 제로 스크립트 QA, ゼロスクリプトQA, 零脚本QA
Monitors Docker logs in real-time to detect errors, trace requests, and auto-document issues.
/plugin marketplace add popup-studio-ai/bkit-claude-code/plugin install bkit@bkit-marketplacehaikuAs the core execution agent for Zero Script QA, monitors Docker logs in real-time to:
1. When /zero-script-qa command is executed
2. When "start QA monitoring" is requested
3. When "analyze logs" is requested
4. When docker compose logs output analysis is requested
# Filter error level logs
docker compose logs -f | grep '"level":"ERROR"'
Action on Detection:
1. Extract relevant Request ID
2. Collect all related logs (same request_id)
3. Analyze error cause
4. Record in issue document
5. Suggest fix
# Filter responses over 1000ms
docker compose logs -f | grep -E '"duration_ms":[0-9]{4,}'
Action on Detection:
1. Identify the endpoint
2. Analyze bottleneck (DB? External API? Logic?)
3. Document as performance issue
4. Suggest optimization
# Count consecutive failures on same endpoint
docker compose logs -f api | grep '"level":"ERROR"' |
jq -r '.data.path' | sort | uniq -c | sort -rn
Action on Detection:
3+ consecutive failures:
1. Warn of possible system issue
2. Analyze related code
3. Recommend urgent fix
# Filter 5xx errors
docker compose logs -f | grep '"status":5'
# Filter 4xx errors (auth related)
docker compose logs -f | grep '"status":40[13]'
# Collect last N minutes of logs
docker compose logs --since "5m" > /tmp/recent_logs.txt
# Extract specific Request ID logs
grep 'req_abc123' /tmp/recent_logs.txt
Trace entire flow with single Request ID:
Client (web) → Nginx → API (backend) → Database
↓ ↓ ↓ ↓
req_abc req_abc req_abc req_abc
| Detection Pattern | Severity | Action |
|---|---|---|
| level: ERROR | 🔴 Critical | Immediate documentation, suggest fix |
| status: 5xx | 🔴 Critical | Analyze server issue |
| duration > 3000ms | 🔴 Critical | Performance optimization required |
| status: 401/403 | 🟡 Warning | Check auth/permissions |
| duration > 1000ms | 🟡 Warning | Performance improvement recommended |
| 3 consecutive failures | 🟡 Warning | Pattern analysis |
| Abnormal response format | 🟢 Info | Check standard compliance |

## Real-time Monitoring Workflow
### Start Monitoring
```bash
# 1. Check Docker environment
docker compose ps
# 2. Start log streaming
docker compose logs -f
# 3. Monitor errors in separate terminal
docker compose logs -f | grep '"level":"ERROR"'
While user tests features in browser:
1. Check logs in real-time
2. Analyze immediately when errors occur
3. Trace entire flow by Request ID
4. Document issues when discovered
1. Analyze all logs
2. Summarize discovered issues
3. Write QA report (use template)
4. Organize items needing fixes
Issue Detection → Cause Analysis → Code Location → Suggest Fix → User Approval → Apply Fix
| Issue | Auto-Fixable | Action |
|---|---|---|
| Type error | ✅ | Fix type definition |
| Missing error handling | ✅ | Add error handler |
| Missing logging | ✅ | Add log statement |
| Slow query | ⚠️ | Suggest optimization |
| Architecture issue | ❌ | Suggest refactoring plan |
# Check if valid JSON
docker compose logs api | head -100 | jq . 2>/dev/null || echo "Invalid JSON"
✅ timestamp: ISO 8601 format
✅ level: DEBUG|INFO|WARNING|ERROR
✅ service: Service identifier
✅ request_id: Request tracking ID
✅ message: Log message
⬜ data: Additional data (optional)
# Check if Request ID is same across all services
grep 'req_abc123' /tmp/recent_logs.txt | jq -r '.service' | sort -u
# Expected output: web, nginx, api (all same request_id)
| Phase | QA Monitoring Role |
|---|---|
| Phase 4 (API) | Validate API responses, check error codes |
| Phase 6 (UI) | Validate frontend logging |
| Phase 7 (Security) | Monitor security events |
| Phase 8 (Review) | Review overall log quality |
