second-brain

Capture and retrieve personal notes — tasks, lessons, ideas, info on people and projects — stored as dated markdown bullets in `~/notes/SecondBrain/`. Use when user says "save to my second brain", "remember that...", "remind me to look into...", "don't let me do X again", "what do I have on X", "second brain about Y", or otherwise wants to capture/recall personal knowledge without organizing it manually.
