Pi coding agent

Pi is a terminal coding agent distributed as a Node.js package. This example pins the tested package version and gives it a copied workspace inside the microVM.

Run Pi

Start Pi

msb run -t --name pi-demo --replace \
  --cpus 2 --memory 2G --root-disk 4G \
  --copy-dir ./my-project:/workspace \
  --workdir /workspace \
  node:24-bookworm-slim -- sh -lc '
    apt-get update &&
    apt-get install -y --no-install-recommends ca-certificates git &&
    npm install -g @mariozechner/pi-coding-agent@0.73.1 &&
    exec pi
  '

msb run -t --name pi-demo --replace `
  --cpus 2 --memory 2G --root-disk 4G `
  --copy-dir ./my-project:/workspace `
  --workdir /workspace `
  node:24-bookworm-slim -- sh -lc '
    apt-get update &&
    apt-get install -y --no-install-recommends ca-certificates git &&
    npm install -g @mariozechner/pi-coding-agent@0.73.1 &&
    exec pi
  '

The tested install downloads 188 packages and takes about a minute on a warm Node image cache. Configure a provider from the TUI when prompted.

Start another session

After leaving Pi, return to the same sandbox and workspace with:

msb exec -t pi-demo -- pi

Verify the installation

Exit Pi and run:

msb exec pi-demo -- pi --version

The pinned example prints 0.73.1.

Export changes

Create a patch inside the sandbox:

msb exec pi-demo -- sh -lc 'cd /workspace && git add -N . && git diff --binary > /tmp/pi.patch'

Copy the patch to the host:

msb cp pi-demo:/tmp/pi.patch ./pi.patch

Check that it applies cleanly before applying it:

git apply --check ./pi.patch

Clean up

msb rm -f pi-demo
