Turn technical conversations, bugs, CI failures, review comments, and repeated agent mistakes into durable project improvements. Use when the user asks what should be automated, documented, tested, added to AGENTS.md/CLAUDE.md, wired into CI, or changed so the same issue does not happen again. This skill is for both non-technical and technical users: it explains the learning in plain English, inspects the repository, chooses the right prevention layer, proposes changes first, and only edits project files when explicitly asked.
