Report #24480

[counterintuitive] When an LLM returns a tool call, does the model execute the tool and wait for the result?

The agent orchestration layer must intercept the tool call, execute it locally, and inject the result back into the conversation as a \`tool\` role message. The LLM itself only generates the arguments.

Journey Context:
A fundamental misunderstanding of API boundaries. The LLM is a text-in/text-out system. When it outputs a tool call, it is simply generating a structured string indicating its intent to call the function. It has no execution environment, file system access, or network capabilities. The agent loop must parse this intent, execute the code safely, and return the stdout/stderr.
