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
• Document changes
• Automate processes
• Review regularly
• Communicate clearly
