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

# Yarbrain CLI instructions

`yarbrain` is the Go CLI that owns every read and write of a user's Yarbrain
vault: a folder of Markdown lessons that agents propose, an independent gate
agent judges, and later sessions confirm or doubt. The repository root
`AGENTS.md` also applies. This file adds the rules for this module.

## Boundaries

- `cmd/yarbrain` owns Cobra commands and flags, stdin and `--input` decoding,
  host session ids from the environment, the JSON envelope, the mapping from
  error codes to exit codes, dependency assembly, and the process exit. Keep
  lesson, trust, and storage policy out of command files.
- `internal/lesson` owns lesson fields, limits, normalization, the content
  digest, and lifecycle transitions. It does no I/O.
- `internal/trust` owns ledger events and the serving rules: credible verdicts,
  contributor sessions, leases, and the limits on doubt, confirm, and defer. It
  does no I/O.
- `internal/vault` owns config and vault resolution, the layout, the format
  version, frontmatter reads and owned-line edits, exclusive creates, the vault
  lock, ledger files, and read-only access to v0.2 content.

How to install

The exact contents, by fingerprint
mdr add yarlson/yarstack/plugins/yarbrain/cli/AGENTS.md@sha256:ec045228988d8756

The line at the top of this page pins the label git:20261104.08c2224, 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.
