## Why demo_vid_generate is rated High

The tool name strongly implies it triggers the actual video generation pipeline, which would involve running Playwright (browser automation), TTS (text-to-speech synthesis), and FFmpeg (media processing) — all external process executions with significant resource usage.

From the tool's own definition: "Tool name 'demo_vid_generate' on a server described as a 'Fleet demo video pipeline — narrated walkthroughs via Playwright, TTS, and FFmpeg'; sibling tools include script drafting, validation, and refinement steps suggesting this is the execution/generation…"

## Use case

AI agents invoke demo_vid_generate to trigger actions in Demo Vid. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)
