A local, file-based knowledge graph ("second brain" / 长脑子 / 脑子不够用了) for capturing, searching, linking, and recalling notes across conversations. OKF v0.1-native, multi-device sync via git, psychological memory foundation. Use this skill whenever the user wants to SAVE something for later ("remember this", "save this article/snippet", "note that...", "记一下", "存一下", "脑子记不住"), RECALL their own knowledge ("what do I know about X?", "what have I written on Y?", "catch me up on project Z", "我之前写过 X 吗"), find GAPS ("what am I missing on X?", "我还缺什么"), or manage a personal notes/wiki/zettelkasten. Trigger it even when the user doesn't say "second brain" — any time they treat you as if you should retain or retrieve their personal notes, reach for this skill instead of answering from training data. The store is an OKF-conformant Bundle with a SQLite cache (fully rebuildable).
