Filing gate for ALL brain writes. Consulted before creating any new brain page to determine the correct path. Reads the ACTIVE schema pack via `gbrain schema show --json` — no hardcoded directory table. Also runs periodic taxonomy drift detection via `gbrain schema review-orphans`.
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
# brain-taxonomist ## Purpose **Gate function:** Before creating ANY new brain page, consult this skill to determine the correct filing path. This prevents misfiling at write time rather than cleaning up drift after the fact. **Drift function:** Periodic scan for pages that have outgrown their current location. ## Contract This skill guarantees: - Every new page is filed at the path determined by the ACTIVE schema pack — never against a hardcoded directory table baked into this skill. - The decision is reproducible: invoking brain-taxonomist twice on the same content produces the same recommended path. - Ambiguous cases surface to the user via `skills/ask-user/` rather than silently picking a default. - Per-source overrides via `--source <id>` are honored — multi-brain users (Persona B) get a different recommendation per source if their packs diverge. - When no matching `page_types[]` entry exists in the active pack, the skill signals to EIIRP Phase 3 (SCHEMA CHECK) rather than picking the closest-fitting fallback. ## Critical: this skill reads the ACTIVE schema pack as data `brain-taxonomist` has NO hardcoded directory table. Every decision is …

How to install
mdr add garrytan/gbrain/brain-taxonomist@sha256:418fd4cdac335555The line at the top of this page pins the label v1.0.0, 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.
