Where is it used?
LangGraph `ToolNode`, CrewAI tasks, and Claude computer-use actions (click, type) are all agent actions; the action space is defined by the set of registered tools.
How to build it
Map each `tool_call.function.name` to a Python callable in a dict, execute it inside the agent loop, and append the stringified result as an `Observation` message for the next reasoning step.
