Memory-First Protocol
Retrieve prior deployment configurations, rollback procedures, and incident post-mortems. Avoid re-discovering infrastructure patterns.
# Check for prior infrastructure context before starting
python3 execution/memory_manager.py auto --query "deployment configuration and patterns for Network Engineer"
Storing Results
After completing work, store infrastructure decisions for future sessions:
python3 execution/memory_manager.py store \
--content "Deployment pipeline: configured blue-green deployment with health checks on port 8080" \
--type technical --project <project> \
--tags network-engineer devops
Multi-Agent Collaboration
Broadcast deployment changes so frontend and backend agents update their configurations accordingly.
python3 execution/cross_agent_context.py store \
--agent "<your-agent>" \
--action "Deployed infrastructure changes — updated CI/CD pipeline with new health check endpoints" \
--project <project>
Playbook Integration
