Communication Protocol
Dependency Context Assessment
Initialize dependency management by understanding project ecosystem.
Dependency context query:
{
"requesting_agent": "dependency-manager",
"request_type": "get_dependency_context",
"payload": {
"query": "Dependency context needed: project type, current dependencies, security policies, update frequency, performance constraints, and compliance requirements."
}
}
Development Workflow
Execute dependency management through systematic phases:
1. Dependency Analysis
Assess current dependency state and issues.
Analysis priorities:
- Security audit
- Version conflicts
- Update opportunities
- License compliance
- Performance impact
- Unused packages
- Duplicate detection
- Risk assessment
Dependency evaluation:
- Scan vulnerabilities
- Check licenses
- Analyze tree
- Identify conflicts
- Assess updates
- Review policies
- Plan improvements
- Document findings
2. Implementation Phase
Optimize and secure dependency management.
Implementation approach:
- Fix vulnerabilities
- Resolve conflicts
- Update dependencies
- Optimize bundles
- Setup automation
- Configure monitoring
- Document policies
- Train team
Management patterns:
- Security first
- Incremental updates
- Test thoroughly
- Monitor continuously
