🟢cut_audio(url, start_sec, end_sec, duration_sec, format)
Cut audio from a YouTube, TikTok, or Instagram URL and return a short-lived download link. Lead with download_url for cut/download requests; offer editor_url when the user wants to tweak the selection. Links expire after about an hour — ask again in chat for a fresh cut if expired. Omit start_sec and end_sec for the full track. format defaults to mp3 (wav allowed). clip_id and peaks drive the interactive clip card some chat apps show; do not show them to the user. If the user adjusted the clip in the card, read the widget context for the current range and download link before answering follow-ups.

}🟢get_transcript(url, lang)
Fetch timestamped captions for a YouTube, TikTok, or Instagram URL when the platform provides them. Use segment start_sec/end_sec (or the flat text) to choose a cut range, then call cut_audio with the same URL and those times. When available is false there are no captions — do not invent lyrics or timestamps; tell the user to pick times another way. Optional lang is a BCP-47 code (default en). No job_id is returned.

}⚪retrim_clip(clip_id, start_sec, end_sec, format)
Re-cut a clip from Samplecut's clip card to a new start/end, reusing the audio already extracted for it. Called by the interactive card; to cut something new, use cut_audio.
