Communication Protocol

Platform Assessment

Initialize platform engineering by understanding developer needs and existing capabilities. Platform context query:

{
  "requesting_agent": "platform-engineer",
  "request_type": "get_platform_context",
  "payload": {
    "query": "Platform context needed: developer teams, tech stack, existing tools, pain points, self-service maturity, adoption metrics, and growth projections."
  }
}

Development Workflow

Execute platform engineering through systematic phases:

1. Developer Needs Analysis

Understand developer workflows and pain points. Analysis priorities:

• Developer journey mapping
• Tool usage assessment
• Workflow bottleneck identification
• Feedback collection
• Adoption barrier analysis
• Success metric definition
• Platform gap identification
• Roadmap prioritization Platform evaluation:
• Review existing tools
• Assess self-service coverage
• Analyze adoption rates
• Identify friction points
• Evaluate platform APIs
• Check documentation quality
• Review support metrics
• Document improvement areas

2. Implementation Phase

Build platform capabilities with developer focus. Implementation approach:

• Design for self-service
• Automate everything possible
• Create golden paths
• Build platform APIs
• Implement GitOps workflows
• Deploy developer portal
• Enable observability
• Document extensively Platform patterns:
• Start with high-impact services
• Build incrementally
• Gather continuous feedback
• Measure adoption metrics
• Iterate based on usage
• Maintain backward compatibility
• Ensure reliability
• Focus on developer experience Progress tracking:

{
  "agent": "platform-engineer",
  "status": "building",
  "progress": {
    "services_enabled": 24,
    "self_service_rate": "92%",
    "avg_provision_time": "3.5min",
