(<n> decisions, <m> todos).` ## At session start, or when the user references the past — RECALL 1. Before answering anything that depends on history ("what did we decide about X", "continue the project", "pick up where we left off"), **search the vault**: read `AI Brain/MOC.md` and grep the `AI Brain/` notes for the topic + entities from the user's request (filename, `#tags`, body text). 2. Open **only the relevant** notes — never load the whole vault. This is the point: pull a few hundred tokens of relevant context instead of re-pasting everything. Follow `[[wikilinks]]` to related notes. 3. Briefly state what you recalled (`📓 From your vault: …`) before continuing, so the user sees the grounding. If nothing relevant is found, say so and proceed fresh. ## Rules - One vault folder (`AI Brain/`), append-only — never overwrite past sessions. - Tag every note (`#tags`) and link it (`[[…]]` + the MOC) so search + the Obsidian graph have anchors. - Recall is **retrieval, not reload**: fetch the minimum relevant notes. That's what keeps token cost low on long-running projects. - Never invent memories. If the vault has no answer, say "not in memory yet." - It's the user's private vault on their disk — read/write only the `AI Brain/` folder; don't expose it. --- Built by **[Ootto](https://www.ootto.ai)** — the AI autopilot that connects your tools once and runs the busywork for you, automatically.

--- name: ai-brain description: > Give Claude a permanent, searchable long-term memory using an Obsidian vault as the store. At the end of a session, summarize what mattered and save it as a Markdown note in your "AI Brain" vault; at the start of a session (or on demand), read back only the relevant past notes. Local markdown you own — connected via the Filesystem MCP. Trigger with "wrap up", "save this session", or "remember this". user-invokable: true argument-hint: "[wrap up | remember this | recall ]" license: MIT metadata: author: Ootto version: "1.1.0" category: memory --- # 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. 2. **Write a structured Markdown note** in this exact shape (Obsidian-friendly tags + links): ``` # Session — — <3–6 word title> #ai-brain # # Related:: [[]], [[]] ## Decisions - — ## Context / facts to remember - ## Built / changed - () ## Open / next - [ ] ``` Keep it tight and skimmable — this is for future retrieval, not prose. 3. **Save it to the vault** via the Filesystem MCP: write the note to `AI Brain/-.md`. If the `AI Brain/` folder doesn't exist yet, create it first. Append-only — never overwrite a past session's note. 4. **Link it in.** Add a one-line pointer to a `AI Brain/MOC.md` index (a map-of-content): `- [[-]] — ` so the brain stays browsable in Obsidian's graph. 5. Confirm in one line: `🧠 Saved to your Obsidian vault — (<n> decisions, <m> todos).` ## At session start, or when the user references the past — RECALL 1.
