Migrate a brain from gbrain-base (or any pack) to gbrain-base-v2's 14-canonical-type taxonomy via gbrain onboard --check + the unify-types Minion handler. Collapses 94 noisy types to 15 canonical with subtypes, alias rows, and link rows. Triggers when an agent notices pack_upgrade_available, type_proliferation, or asks "what is the canonical taxonomy / how do I clean up my page types".

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

# Schema Unification (gbrain-base → gbrain-base-v2)

v0.41.22 ships **gbrain-base-v2** — a 15-type DRY/MECE taxonomy (14 canonical + `note` catch-all) — as the install default for new brains. Existing brains on `gbrain-base` can opt in via the `pack_upgrade_available` onboard finding + the `unify-types` PROTECTED Minion handler.

This skill is the playbook for that migration.

## brain_first: exempt

This skill is ABOUT the brain's shape — it can't depend on the brain it's reshaping. No `gbrain search` lookup first; jump straight to onboard.

## When this skill fires

- Agent runs `gbrain onboard --check` and sees `pack_upgrade_available` or `type_proliferation` warnings
- User asks "what is the canonical taxonomy / how do I clean up my page types / migrate to v2"
- A `dangling_aliases` finding surfaces (post-unify GC)
- An agent ingesting from a custom pack wants to consult the v2 taxonomy as a reference

How to install

The exact contents, by fingerprint
mdr add garrytan/gbrain/schema-unify@sha256:36259f1510fd6932

The line at the top of this page pins the label git:20261007.590bb9a, 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.
