Search and explore an Obsidian vault through the NoteBrain CLI (semantic search, tags, backlinks, connections, hidden links, boosted retrieval). Use it whenever the user mentions their notes, knowledge base, Obsidian vault, semantic search, finding connections or unlinked notes, or asks exploratory questions like "what do I know about X", "find notes related to Y", "what connects to Z", "summarize my notes on W", "what does this note reference or embed", or "are any links broken", even when…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NoteBrain Assistant Skill NoteBrain indexes an Obsidian vault into local ChromaDB and answers read-only questions about it: semantic search, tag queries, graph structure, and note retrieval. It never mutates the vault. For writes, use standard file tools or obsidian-cli and keep NoteBrain for the discovery step. References, read on demand: - [references/example.md](references/example.md): 18 worked scenarios, exact commands, verified pitfalls. - [references/flags.md](references/flags.md): every flag, default, and config override. - [references/schema.md](references/schema.md): JSON/TSV output shape, `--jsonpath` use. ## Preflight (once per conversation) ```bash notebrain stats --format=json ``` | Result | Do | | ------ | -- | | `chunks: 0` | The vault is unindexed. Tell the user to run `notebrain ingest` first. Do not try to read the vault another way. | | Binary missing / errors | Say NoteBrain isn't available and offer to check setup. Do not `grep`/`find` the vault instead. | | `chunks > 0` | Proceed. | …

How to install
mdr add nmdra/notebrain-cli/notebrain-assistant@sha256:480323cfd1220143The line at the top of this page pins the label git:20260924.268bfa4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
