Answer a question from the brain vault, the local markdown knowledge base, and cite the notes behind the answer. Use when the user says "/ask", "ask the brain", "what do we know about", "what do my notes say", "have I written about", or wants an answer from saved knowledge before anything is looked up elsewhere. Read-only. Backed by the brain MCP (brain_hybrid_search, brain_search, brain_peek, brain_read, brain_backlinks) with the `brain` CLI as fallback.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
12 rules. 0 are common, 8 are distinctive, and 4 are very specific to this project.
0
Common
Most of the 62 edited versions we read keep these.
8
Distinctive
This author's own choices. Worth a look.
4
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 19
Prefer the MCP tools: brain_hybrid_search, brain_search, brain_peek, brain_read, brain_backlinks.
- Very specific: line 27
Find the notes: Run brain_hybrid_search with the question in the user's words.
- Very specific: line 41
Prefer notes/ and MOCs/ over inbox/, and a note with a higher evidence grade over a lower one.
- Distinctive: line 48
Answer: Follow the reply rules below.
- Distinctive: line 52
Every read tool returns the fields that say how far to trust a note.
- Very specific: line 65
Search leaves out revoked notes (superseded, retracted, withdrawn).
- Distinctive: line 80
Keep what the notes say apart from what you add.
- Distinctive: line 82
When notes disagree, show both claims with their grades and dates.
- Distinctive: line 84
When the vault has no answer, say that in the first line.
- Distinctive: line 89
Do not write, edit or promote a note from this skill.
- Distinctive: line 90
Do not fill a gap in the notes with a guess that reads like a citation.
- Distinctive: line 91
Do not read a whole vault to answer one question.
“Common” is measured: kept by at least 6 in 10 of the 62 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
ask
Answers a question from the brain vault and shows which notes the answer comes from. The vault is the source. Nothing in the answer comes from the web or from model memory unless the reply says so.
ask only reads. It never writes, edits or promotes a note. To add knowledge,
capture it with brain capture or brain_write. To research a topic the
vault does not cover, say so and let the user choose the next step.
Tools
Prefer the MCP tools: brain_hybrid_search, brain_search, brain_peek,
brain_read, brain_backlinks. The brain CLI is the fallback when the MCP
server is not connected (brain hybrid-search, brain search, brain peek,
brain read, brain backlinks). On a tool error or an empty result that
looks wrong, call brain_doctor before a retry.
Steps
- Find the notes. Run
brain_hybrid_searchwith the question in the user's words. It joins a literal search and a vector search. When itswarnings[]say the vector half did not run, the hits are literal only: follow up withbrain_searchon one or two distinct terms from the question. When it returns an error, do the same and tell the user in one line that the vector search is down. Abrain_searchquery is zoekt syntax: two words mean both must be in the same note, anda|bmeans either. - Widen once on a miss. Try a synonym, the singular form, or a broader
term. Search covers every vault and every tier, so do not narrow with
tierorvaultunless the user named one. After two misses stop and report that the vault holds nothing on the question. - Pick what to read.
brain_peekthe top hits, five at most. Peek is cheap: it returns the frontmatter, the first lines and the backlink count. Prefernotes/andMOCs/overinbox/, and a note with a higher evidence grade over a lower one. - Read the notes that answer.
brain_readeach one, withstart_lineandend_linewhen only a section matters. A map of content (a note underMOCs/) is an index: follow its wikilinks to the notes it lists. When a note points at a neighbour that looks closer to the question, checkbrain_backlinksand read that one too. - Answer. Follow the reply rules below.
What the vault says about trust
Every read tool returns the fields that say how far to trust a note. Carry them into the answer.
| Field | Value | What to do |
evidence | A, B | State the claim plainly |
evidence | C | State the claim and say the evidence is weak |
evidence | D | The claim is refuted. Say so. Never give it as the answer |
evidence | mixed | Grades sit beside each claim in the body. Use the grade of the claim you quote |
status | raw | An unchecked capture from inbox/. Say it is unverified |
status | disputed | Show the banner from brain_read before the claim |
stale | true | The note is past its review_by date. Say it may be out of date |
Search leaves out revoked notes (superseded, retracted, withdrawn). Keep it
that way: set include_revoked only when the user asks what the vault used
to say.
The reply
- Lead with the answer in one or two sentences.
- Then the sources, one line each: the note title as a link, its evidence grade when it has one, and a flag for raw, disputed or stale.
- Link a note to the brain web view when the machine runs it: the root URL
plus
?note=and the URL-encoded note ref in thevault:pathform. With the hostbrain.this, the notepersonal:notes/ops/k8s-upgrades.mdishttp://brain.this/?note=personal%3Anotes%2Fops%2Fk8s-upgrades.md. Without the web view, give thevault:pathref. - Quote a note for a number, a date or a decision. Paraphrase the rest.
- Keep what the notes say apart from what you add. Mark an inference as yours.
- When notes disagree, show both claims with their grades and dates. Do not pick a side without saying why.
- When the vault has no answer, say that in the first line. Offer the general answer as a separate, labelled part only when the user wants it.
Do not
- Do not write, edit or promote a note from this skill.
- Do not fill a gap in the notes with a guess that reads like a citation.
- Do not read a whole vault to answer one question. Five notes is the cap; ask the user to narrow the question past that.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
