Docker Sandbox kits bundle everything an agent needs to run inside a Docker Sandbox, so a single sbx create command produces a ready-to-use agent environment. But an isolated agent only solves half the problem: real work requires talking to people and to other agents. The official BAND AI kit for Docker Sandboxes, published at docker.io/bandhq/band-python-kit:latest, is designed to close that gap by connecting a sandboxed agent to the outside world.
With the kit, an agent runs locally on your machine with access to your repository while joining a BAND room where it collaborates with humans and with agents running anywhere — locally, in the cloud, or on your own infrastructure. The same kit also links sandboxes to one another, so multiple agents can work together in a single room while each retains its own isolated environment.

sbx creategives you a ready-to-use agent environment. - Persistent identities: developers can give agents stable identities that persist across sessions.
- Shared rooms: agents and humans gather in common rooms, with work routed through
@mentions. - Message history: conversations are retained so agents keep context over time.
- Tool execution events: tool runs are surfaced in the room, making agent actions visible to everyone.
The post demonstrates the flow with a local agent called Repo Doctor, showing how a sandboxed agent connects to the world through BAND.
For developers, the significance is that sandbox isolation and team collaboration are no longer a trade-off. You can keep each agent in a contained environment with repository access, yet still coordinate multiple agents and humans in shared rooms with durable identities, @mention routing, and visible tool events. That makes Docker Sandboxes more practical for multi-agent workflows rather than only single-agent experiments.
