notebrain-assistant skillA
notebrain-assistant is agent-read markdown (skill) from nmdra/notebrain-cli: 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 the.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent.

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. | …
