Professional Brain Skill

🚀 New to this? Start with the 5-minute Quickstart — a folder + one file, with a worked example. This file is the full reference.

Most skills start cold — you paste the same context every time, and decisions made six weeks ago lose the why. This skill gives the library a memory: a plain-markdown brain/ folder on disk that skills read before they answer and write to after. No vector DB, no cloud — just grep-able files you (and Claude) can audit and edit.

This is the state layer of an AI teammate. Pair it with the action layer (skills that file tickets / open PRs) and you get a loop: recall → do the work → record the decision → review.

What This Skill Produces

• A scaffolded brain/ folder with a fixed schema (see below).
• Provenance-tagged knowledge — every claim says where it came from and how strong it is.
• Four operations you can invoke: init, ingest, recall, review.
• A standing contract other skills follow: read the relevant brain files first; write durable outcomes (decisions, new facts, stakeholder asks) back.
