Memory-First Protocol
Retrieve prior error resolutions and debugging strategies. The hybrid search excels here — BM25 finds exact error codes/stack traces while vectors find semantically similar past issues.
# Check for prior debugging/diagnostics context before starting
python3 execution/memory_manager.py auto --query "error patterns and debugging solutions for Devops Troubleshooter"
Storing Results
After completing work, store debugging/diagnostics decisions for future sessions:
python3 execution/memory_manager.py store \
--content "Root cause: memory leak from unclosed DB connections in pool — fixed with context manager" \
--type error --project <project> \
--tags devops-troubleshooter debugging
Multi-Agent Collaboration
Store error resolutions so any agent encountering the same issue retrieves the fix instantly instead of re-debugging.
python3 execution/cross_agent_context.py store \
--agent "<your-agent>" \
--action "Debugged and resolved critical issue — root cause documented for future reference" \
--project <project>
Self-Annealing Loop
When this skill resolves an error, store the fix in memory AND update the relevant directive. The system gets stronger with each resolved issue.
BM25 Exact Match
Error codes, stack traces, and log messages are best found via BM25 keyword search. The hybrid system automatically uses exact matching for these patterns.
