A feature I'd like in AI tools:

An agent running in the background, monitoring everything, and sending you a notification when it detects something you may want to know about.

For coding, it'd tell you about bugs, refactoring suggestions, missing test cases, outdated docs, etc.

For a presupposed tool for writing novels, the background agent could automatically scan for plot holes or inconsistencies.

Current tools focus on human-initiated flows. Even with things becoming more "agentic," that paradigm has stuck. AI-initiated flows seem underdeveloped.

Going through such notifications seems like the perfect thing to do while waiting for claude code or w/e to finish running. (Rather than going on tiktok and switching context off work entirely)
