Agentbox is a Debian Trixie container with Copilot CLI, Claude, Codex, and Pi preinstalled alongside git, gh, bun, uv, and brew.
It provides Docker, ssh, and a GUI image with RDP (disabled by default, enabled via env vars) and an XFCE desktop environment, as well as a workspace skeleton with SKILL.md templates to help coding harnesses feel at home.
The entrypoint checks ENABLE_DOCKER, ENABLE_SSH, and ENABLE_RDP and starts only what you asked for — all three default to off. The agent user gets passwordless sudo, and the workspace skeleton at /home/agent/workspace-skel copies into /workspace on first use without overwriting files.
Copilot CLI, Claude, Codex, Pi baked in. Toad, OpenCode and Gemini via make targets.
Docker, SSH, RDP all off by default. Enable explicitly.
:latest is headless. :gui adds XFCE, XRDP, VS Code.
SKILL.md templates without overwriting existing files.
Run privileged and agents get their own Docker daemon.
