yt-chapters

Chapters from a timestamped transcript. Use it for "add chapters", "timestamps", "break this video into sections". From this skill's folder:

python3 scripts/chapters.py transcript.srt --target 8

The input is the transcript (srt, vtt or whisper json). When a shell is available and the video is on YouTube, this saves its automatic captions (use the video's language code):

yt-dlp --skip-download --write-auto-subs --sub-langs ko --convert-subs srt "<video link>"

Without a shell (claude.ai, ChatGPT) the script cannot run: draft the boundaries by hand from the transcript and check the rules below yourself.

The rules, which are not optional
