What list_templates does on VideoGen Advisor

AI agents call list_templates to retrieve information from VideoGen Advisor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_templates needs a policy

This tool queries and returns a list of existing templates—a read-only operation that retrieves information without modifying, executing, or deleting anything. It has minimal blast radius if misused; an AI agent can only discover what templates exist, not create unwanted content or cause damage.

From the tool's definition Tool name 'list_templates' and description 'List available HeyGen templates' indicate a retrieval operation with no side effects. The phrase 'with customizable variables' describes what those templates contain, not what the tool does to data.
