bstack primer — the Broomva Stack: twenty irreducible automation primitives (P1–P20) that turn an agent-driven workspace into a self-operating system. This is the AGENT-READABLE PRIMER (primitive contract + short-name index + when each fires), NOT the CLI. The bstack CLI + governance substrate (bin/, doctor, templates, hooks) is a separate product installed by clone + bootstrap (git clone https://github.com/broomva/bstack && ./bin/bstack bootstrap) — do NOT `npx skills add broomva/bstack`…
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.

# bstack — the Broomva Stack (primitives primer) **A portable harness metalayer for AI-native development.** Twenty irreducible primitives that turn any agent-driven workspace into a self-operating system. Each primitive closes one failure mode that otherwise drifts into entropy in unsupervised agent sessions. > **This file is the agent-readable *primer*, not the CLI.** It teaches you the > primitive contract so you can reason with it. The bstack CLI + governance substrate > (the `bstack` binary, `doctor`, templates, hooks, schemas) is a **separate product**: > > ```bash > git clone https://github.com/broomva/bstack.git > cd bstack && ./bin/bstack bootstrap > ``` > > Do **not** `npx skills add broomva/bstack` — bstack has a repo-root `SKILL.md` > beside `bin/`, so skills.sh copies only that file and drops the CLI > ([vercel-labs/skills#1523](https://github.com/vercel-labs/skills/issues/1523)). > `bstack bootstrap` installs the companion-skill roster from **this monorepo**: > `npx skills add broomva/skills --skill <name>` per entry. ## Referencing primitives Use the `Name (Pn)` form in prose — *"applying Snapshot (P15)"*, *"via Dep-Chain …

How to install
mdr add broomva/skills/bstack@sha256:0dbe7502e5943a19The line at the top of this page pins the label git:20260927.cda4472, 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.
