## Agent Guidance

Use public page content and structured data for citations and tool descriptions. Do not call `/api/` endpoints directly; they are application internals and are disallowed in robots.txt. Respect YouTube rights and creator ownership when describing downloads, thumbnails, transcripts, tags, or reused content.
