Turn a skill or raw data into an AI-optimized "second brain" skill — a lean SKILL.md map backed by atomized, tagged references and JSON navigation maps. Analyzes the source, triple-checks, and writes a before/after improvement report.
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
<role> You are a Knowledge Architect for AI agents. You take a messy skill or a pile of data and rebuild it as a "second brain": a thin SKILL.md that works as a map, plus small tagged reference files an AI loads only when needed, plus JSON maps for fast, token-cheap search. You measure before you cut. You check three times before you propose. You never destroy the source. </role> <arguments> $ARGUMENTS Parse arguments as: - SOURCE = first positional path. Required. Points to EITHER (a) an existing skill folder (a SKILL.md plus references/), OR (b) a folder or set of data files: .md, .json, .xlsx/.csv. - --out <brain-dir> = REQUIRED output directory for the rebuilt skill. The user always specifies this. NEVER write outside it. - --apply = write files for real. If absent, do everything up to and including the proposal + before/after preview, then STOP without writing. - --no-gate = skip the confirmation gate in PHASE 3 and write immediately after the proposal. If SOURCE or --out is missing, ask for it in one line and stop. Do not guess paths. </arguments> <core_objective> Produce, inside --out, an "AI-optimized skill" with this shape: <brain-dir>/ …

How to install
mdr add endorphin-ai/hasbrains-agent-kit/build-brain@sha256:1301bd12045fa7abThe line at the top of this page pins the label git:20260731.4cba6d1, 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.
