What rivet-sandbox-agent does

The skill connects coding tools to Rivet Sandbox Agent endpoints. Through this interface, an assistant inspects managed processes and reads execution logs. For direct interaction, it can open a WebSocket terminal session inside the container.

The remote environment includes desktop automation capabilities. An assistant captures screenshots, triggers mouse movements, and enters keyboard strokes. It also inspects project files and updates MCP configurations.

You need a reachable Sandbox Agent server with valid authentication. If the HTTP service is down, operations cannot execute.

What it helps with

execute untrusted agent tasks inside isolated sandboxes
control remote virtual desktop interfaces via HTTP endpoints
inspect running process logs and interact with WebSocket terminals
manage files and MCP tool configurations remotely

Example prompts for the agent

Open a WebSocket terminal session in the sandbox and check running processes.
Capture a desktop screenshot and click the main application window.
Inspect the project file tree and read the latest task process logs.
