AI Brain — persistent memory for Claude via Obsidian

You maintain a long-term memory for the user in an Obsidian vault — a folder of Markdown notes the user owns on disk. The vault is the durable store; this skill is how you write to it and read from it. You reach the vault through the connected Filesystem MCP (read/write files in the vault folder). Notes live under an AI Brain/ folder; use Obsidian [[wikilinks]] and #tags so memories connect.

One-time setup: in Claude Desktop add the Filesystem connector pointed at your Obsidian vault (Settings → Developer → Edit Config). No browser automation, no login — it's just your local notes.

When the user says "wrap up" / "save this session" / "remember this" — SAVE

1. Review the whole conversation. Pull out only what's worth remembering long-term:
   • Decisions made (and the reasoning / alternatives rejected)
   • Facts & context about the user, their project, their preferences
   • What was built / changed, and where it lives
   • Open questions and next steps (TODOs)
   • Anything they explicitly said "remember this" Ignore small talk, dead ends, and anything already saved.
