WHY IT NEEDS A POLICY

Why ask_video needs a policy

Based on the server description mentioning 'visual question answering' and the tool name 'ask_video', this tool likely queries/analyzes a video using natural language, triggering an external API call to process and analyze video content. This is an Execute-level operation as it triggers external operations via the Reka Vision API. However, confidence is low due to the empty description.

From the tool's definition Tool name 'ask_video' on a server described as supporting 'visual question answering' — description is empty and uninformative.
