Consult, capture, and acquire knowledge in koan's OKF-conformant docs/ and specs/ bundles. Use for /brain ask <question> (alias: /brain search <question> — consult docs/ and specs/ before planning/research/refactor, index-first, with page citations), /brain sync (close the loop after implementing a feature — refresh frontmatter/description and regenerate indexes), /brain ingest <path|url|"idea sentence"> (capture external material as a durable, cited reference page), /brain lint…

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

## User Input

```text
$ARGUMENTS
```

`brain` is self-sufficient: it owns both *acquisition* (`raw/` → `docs/reference/*.md`)
and index-first navigation for `docs/` and `specs/` directly — it does not depend on or
escalate to the `llm-wiki` plugin's `/wiki:*` commands. That plugin's differentiating
capabilities beyond plain index-first reading (BM25 fallback search, graph-assisted
lookup, `[[wikilink]]` backlink search, synthesis-page file-back) are either blind here
(the plugin's bundled scripts don't follow the `wiki/` symlinks) or architecturally
inapplicable (koan has no graph layer, uses plain markdown links not wikilinks, and has
no `synthesis` page type) — see `wiki/SCHEMA.md` for the full rationale.

**Before any subcommand except `help`, read `wiki/SCHEMA.md`** (wiki-directory-level
conventions), then whichever of `docs/SCHEMA.md` / `specs/SCHEMA.md` is relevant to the
bundle in question. Those files are the binding conventions — `docs/SPEC.md` is the
normative, bundle-agnostic OKF v0.1 spec they build on.

Parse `$ARGUMENTS` for the subcommand (first word) and its remaining argument. If
`$ARGUMENTS` is empty, go to "Bare invocation" below.

How to install

The exact contents, by fingerprint

mdr add anantys-oss/koan/brain@sha256:a8ed638bc63eabdb

The line at the top of this page pins the label git:20260710.efa0208, 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.
