The workflow uses two agents: the built-in Security Analyst Agent for quick first-pass reviews, and a custom Detection Engineering Assistant built with a detailed system prompt encoding team-specific context including SIEM log sources, detection philosophy, and MITRE ATT&CK mapping. The custom agent reads closed incident issues and produces structured gap reports with ATT&CK technique IDs, missed detection descriptions, relevant log sources, and recommended detection approaches. Key lessons include treating the system prompt as a living document, improving incident documentation quality, and using the agent as a force multiplier rather than a replacement for human engineers. ## Full article daily.dev links to this article rather than hosting it.
