Gives Claude persistent memory across sessions using semantic search instead of just dumping everything into context. You write notes with markdown and tags, then search them later with natural language queries or build context around specific topics. The build-context command is the interesting bit, it pulls together related notes for whatever you're working on. Best for keeping a running log of decisions, patterns you've learned, or project-specific knowledge that you want Claude to remember next time. You'll need to install basic-memory via pip first, and it helps to be disciplined about actually writing notes during your sessions instead of just at the end.
