What is detection gap analysis in security?

Name it, describe, craft a detailed system prompt with your env knowledge. Invoke from issues.

Nah — accelerates them. Still need humans for nuance, validation.

Post-incident drudgery? GitLab's betting AI agents will end it. But in security, promises like this often crumble under real attacks.
