RemoteCodeExecutor
llmling_agent.resource_providers.codemode.code_executor
Provides secure code execution with tool access via FastAPI server.
    ToolServerLifecycleHandler
    llmling_agent.resource_providers.codemode.code_executor
    Manages FastAPI server lifecycle for tool access.

      🛈 DocStrings

      Code execution provider with secure tool isolation via FastAPI server.

      RemoteCodeExecutor dataclass

      Provides secure code execution with tool access via FastAPI server.

      Architecture: - FastAPI server runs in HOST environment with tool routes - User code runs in SANDBOX environment (Docker, E2B, etc.) - Sandbox makes HTTP calls to server for tool execution
