1. A method, comprising: receiving, at a server, a user request for execution of one or more tool calls; generating, by a large language model (LLM), a code block in a programming language, the code block configured to encapsulate the one or more tool calls; executing, by the server, the code block in a sandbox; in response to obtaining a pending tool call, pausing execution of the code block; transmitting the pending tool call to a client for execution; receiving, from the client, a first result of the pending tool call; resuming execution of the code block and substituting the first result of the pending tool call for the pending tool call in the code block; and returning a second result of the executed code block to the LLM.
