Not a prompt pack

Turn any repo into a governed workspace.

It writes your repo's contract, deniesa destructive tool call before it executes, and leaves a receipt for every execution. One binary, no service, no account, no token meter.

Get started

Up and running in four steps.

Two in your terminal, two in your editor — every step shows you exactly where you are, so nothing runs in the wrong place.

  1. Your terminalonce per machine, inside your repo

    Install it, and write the contract

    $ bun add -g ai-engineering@latest && ai-eng init
    • npmSame ritual, other messenger: npm install -g ai-engineering@latest && ai-eng init.
    • initIdempotent. Run it again whenever you like — Bun 1.4+ is the only floor.
    • ai-eng upgradeShows the changelog, asks first, hands the install to bun or npm.
    • ai-eng updateRewrites its own files from the binary you already have. No network at all.
  2. Your terminalinside your repo

    Prove the install

    $ ai-eng doctor

    Health checks, plus one real adversarial payload fired at the guard chain — so you are not taking the guards on faith.

  3. Your terminalone command per host

    Turn on the editors you use

    $ ai-eng config --add cursor

    It enables the surface and regenerates its adapter; --remove takes one out and leaves the rest of your files alone.

  4. In your editorthe agent keeps its own editor

    Work the way you already do

    › /ai-brainstorm

    The guard screens each call before it runs, the milestone gets a contract you approve, and every execution leaves a receipt.
