# π€ Dependabot Auto-Triage System
## Overview
This repository implements a comprehensive **Dependabot Auto-Triage System** that intelligently manages dependency updates, security alerts, and vulnerability responses with minimal manual intervention.
## π Security-First Approach
### Intelligent Risk Classification
Dependencies are automatically classified into security risk categories:
#### π **Security-Critical** (Manual Review Required)
- **Database Libraries**: `mssql`, `tedious`
- **Authentication**: `@azure/identity`, `@azure/keyvault-secrets`, `aws-sdk`, `@aws-sdk/*`
- **SQL Processing**: `node-sql-parser`
- **Impact**: Core functionality, potential breaking changes
- **SLA**: Review within 24-48 hours
#### π§ **Development Dependencies** (Auto-Merge Eligible)
- **Code Quality**: `eslint*`, `prettier*`, `*lint*`
- **Testing**: `vitest*`, `@vitest/*`, testing tools
- **Development Tools**: `husky`, `lint-staged`
- **Impact**: Development experience only
- **SLA**: Auto-merge after tests pass
#### π **Documentation/Utility** (Auto-Merge Eligible)
- **Documentation**: `markdownlint*`, documentation tools
- **Utilities**: `winston*`, `js-yaml`, `chalk`, `yargs`
- **Impact**: Non-critical functionality
- **SLA**: Auto-merge after tests pass
## π Auto-Merge Workflow
### Trigger Conditions
Auto-merge is enabled when **ALL** conditions are met:
1. β
**PR Author**: Created by `dependabot[bot]`
2. β
**Tests**: Full test suite passes (508 tests)
3. β
**Dependency Type**: Development/utility/docs dependencies
4. β
**Update Type**: Patch or minor versions only
5. β
**No Breaking Changes**: No major version bumps
### Security Update Priority
**Security updates are ALWAYS auto-merged** regardless of dependency type if:
- Tests pass
- Contains keywords: `security`, `vulnerability`, `cve`
- No test failures or regressions
### Manual Review Triggers
Auto-merge is **disabled** for:
- π¨ **Major version updates** on production dependencies
- π **Core database libraries** (`mssql`, `tedious`)
- π **Authentication libraries** (Azure, AWS)
- β **Failed tests** or CI checks
- π§ **Breaking changes** detected
## π Security Alert Triage
### Daily Monitoring
The system runs automated security scans:
- **Schedule**: Daily at 6:00 AM UTC
- **Triggers**: Also runs on dependency file changes
- **Scope**: All npm dependencies and GitHub Actions
### Automatic Issue Creation
For each security alert, the system:
1. **Creates GitHub Issue** with detailed analysis
2. **Assigns Labels** based on severity
3. **Sets Priority** with defined SLA
4. **Provides Action Plan** with specific steps
### Severity-Based SLA
| Severity | Response Time | Action Required |
| ----------- | ------------- | ---------------------- |
| π¨ Critical | 24 hours | Immediate patch/hotfix |
| β οΈ High | 48 hours | Urgent update |
| π Medium | 1 week | Standard cycle |
| βΉοΈ Low | Regular cycle | Next release |
## π§ Configuration Files
### Core Configuration
- **`.github/dependabot.yml`**: Enhanced Dependabot configuration
- **`.github/workflows/dependabot-auto-merge.yml`**: Auto-merge logic
- **`.github/workflows/security-triage.yml`**: Security alert monitoring
### Supporting Files
- **`.github/SECURITY.md`**: Security policy and reporting procedures
- **`.github/PULL_REQUEST_TEMPLATE/dependabot.md`**: PR review template
- **`.github/security-metrics.json`**: Real-time security status tracking
## π Monitoring and Metrics
### Security Metrics Tracking
The system maintains real-time metrics:
```json
{
"last_updated": "2025-08-31T06:29:32.000Z",
"open_alerts": 0,
"status": "secure",
"next_scan": "2025-09-01T06:00:00.000Z"
}
```
### Workflow Status
Monitor the auto-triage system:
```bash
# Check recent Dependabot activity
gh run list --workflow="dependabot-auto-merge.yml"
# Check security alert triage
gh run list --workflow="security-triage.yml"
# View current security status
cat .github/security-metrics.json
```
## π οΈ Manual Operations
### Force Security Scan
```bash
# Trigger manual security triage
gh workflow run security-triage.yml
# Check for new Dependabot alerts
gh api repos/$REPO/dependabot/alerts
```
### Override Auto-Merge
To prevent auto-merge for a specific PR:
1. Add label `manual-review-required`
2. Remove `auto-merge-eligible` label
3. Comment with override reason
### Emergency Security Response
For critical vulnerabilities:
1. **Immediate Response**: Create hotfix branch
2. **Emergency PR**: Bypass normal review for critical fixes
3. **Post-Deploy**: Monitor for regressions
4. **Documentation**: Update security metrics
## π Troubleshooting
### Common Issues
#### Auto-Merge Not Working
1. **Check PR labels**: Ensure correct classification
2. **Verify tests**: All 508 tests must pass
3. **Review permissions**: GitHub token needs write access
4. **Check workflow logs**: Look for errors in auto-merge workflow
#### Security Alerts Not Creating Issues
1. **Verify permissions**: `security-events: read` and `issues: write`
2. **Check API access**: GitHub token has repository access
3. **Review workflow logs**: Check for API rate limits
#### False Positives
1. **Update ignore rules** in `dependabot.yml`
2. **Adjust classification** in auto-merge workflow
3. **Add manual override labels**
## π Best Practices
### For Developers
1. **Monitor auto-merged PRs**: Review changes even if auto-merged
2. **Test locally**: Verify functionality after security updates
3. **Update ignore rules**: Keep Dependabot configuration current
4. **Respond to alerts**: Follow SLA for manual review items
### For Maintenance
1. **Weekly review**: Check auto-merge effectiveness
2. **Monthly audit**: Review security alert response times
3. **Quarterly update**: Refresh classification rules
4. **Annual review**: Update security policy and procedures
## π― Success Metrics
