Blume

Blume is a desktop sidecar that runs locally to help you monitor and improve your coding agent sessions. It works alongside Claude Code, Codex, Cursor, and other supported coding harnesses, giving you a clear view of what your agents are actually doing while they work.

With Blume, you can track hidden rules and configuration files, keep an eye on usage, and spot repeated corrections or workflows that keep coming up. Instead of guessing why your agent keeps making the same mistake, you get concrete signals about what is going wrong.

Based on what it observes, Blume suggests practical updates such as new rules, skills, and verification steps. You stay in control: preview each proposed change, approve it, dismiss it, or save it for later.
