# AGENTS.md — pi-devbox

Container image that adds pi coding-agent on top of the opencode-devbox base image.

## Repository layout

- `Dockerfile` — single-stage build, `FROM opencode-devbox:base-latest`, installs pi + companion repos
- `docker-compose.yml` — compose file for local use
- `.env.example` — environment variable template
- `scripts/smoke-test.sh` — sanity checks run by CI before pushing to Docker Hub
- `.gitea/workflows/docker-publish.yml` — CI pipeline: smoke amd64 → multi-arch push → update Hub description

## Versioning scheme

- Tags follow the pi npm version: `v{pi_version}[letter]`
- Bump `PI_VERSION` build-arg default in `Dockerfile` when cutting a new release
- Docker Hub: `joakimp/pi-devbox:vX.Y.Z` + `joakimp/pi-devbox:latest`

## Release-day checklist

1. Bump `PI_VERSION` in `Dockerfile` (or leave as `latest` to pick up current)
2. Update `CHANGELOG.md`: promote `Unreleased` → `vX.Y.Z — YYYY-MM-DD`
3. Add fresh `## Unreleased` section
4. Commit, tag `vX.Y.Z`, push tag → CI fires automatically

## Key facts

- **Base image**: `joakimp/opencode-devbox:base-latest` — rebuilt whenever opencode-devbox cuts a new base
- **pi binary**: baked at `/usr/bin/pi` (system npm prefix); `NPM_CONFIG_PREFIX=/home/developer/.pi/npm-global` at runtime so user-installed pi/packages land on the named volume
- **Companion repos**: pi-toolkit and pi-extensions cloned to `/opt/` at build time; `entrypoint-user.sh` (inherited from base) deploys symlinks to `~/.pi/agent/` on container start
- **MemPalace**: fully operational — inherited from base image; bridge extension deployed by entrypoint

## Conventions

- Do NOT call `mempalace-toolkit/install.sh` in the Dockerfile — the base entrypoint handles it
- `NPM_CONFIG_PREFIX=/usr` must be set per-RUN for any build-time `npm install -g` to keep baked binaries off the volume-shadowed path
- The smoke test threshold is 2200 MB — update if the image legitimately grows past it
