learn

Use when a lesson should outlive the session — 'remember this for next time', capturing a drill/retro/review finding, or asking whether the store already knows the answer. Thin wrapper over the bro CLI: bro learn is the lesson store; the learn connector injects matched lessons at session-start, prompt-submit, and post-tool. Requires bro (npx -y @broject/bro@0) and bd.
