Functions exposed to the LLM to take actions

Name	Description
find_channelA	Resolve a channel handle, URL, id or name to a channel with its stats. Useful on its own to confirm which channel a name refers to before searching.
search_channel_videosA	Search one channel's videos by keyword, e.g. the latest iPhone review on MKBHD. Costs 100 YouTube quota units per 50 results. When you want recent uploads and have no keyword, use list_channel_videos instead — it is 100x cheaper.
list_channel_videosA	List a channel's uploads newest first, optionally within a date range. Example: everything MKBHD posted in the last year, via published_after='1y'.
get_video_transcriptA	Get a video's transcript as '[MM:SS] text' lines you can quote and cite. Quote the timestamps back so claims stay traceable, e.g. "at [03:15] he says the battery is 17% larger than last year". Narrow long videos with start_seconds and end_seconds. Reads public caption tracks, so it costs no API quota.
get_video_detailsA	Get a video's full description, extracted links, tags and engagement counts. The links list is what the creator cited in the description — sources, products, sponsors and their own other videos.
