Action Space is the set of tools, operations, permissions, or moves available to an agent when performing a task. A well-scoped action space should be sufficient for the task while limiting unnecessary capabilities that may increase errors or governance risk.
The set of resources an agent can use to perform a task. Action space might include the tools and APIs that the agent can invoke and the permissions the agent holds. In general, the action space should be just big enough for the agent to perform the task. If the action space is too small, the agent might have insufficient resources to perform the task. If the action space is too large, the agent tends to become more error prone.
