Bash sandbox

FLOWRA_REMOTE_BASH

Destructive

Run bash on the same remote sandbox as FLOWRA_JS_REMOTE_WORKBENCH for this session.id. Files under /home/user/files stay between calls. The shell itself starts fresh each time.

With session.id and useWorkbenchSnapshot (default true), the latest FLOWRA_MULTI_EXECUTE_TOOL snapshot is at /home/user/files/multi_execute.json (also FLOWRA_WORKBENCH_JSON). That snapshot only exists if the earlier call set syncResponseToWorkbench: true.

Use this for shell work on those files: jq, grep, sort, unzip, wc, listing directories. It has no run_tool, invoke_llm, or proxy_execute helpers and keeps no variables between calls. To call app tools, an LLM, or a connected API from the sandbox, or to keep state across steps, use FLOWRA_JS_REMOTE_WORKBENCH. Neither tool can call FLOWRA_MULTI_EXECUTE_TOOL or any other meta tool.
