Bilibili Video Summary

Create local Markdown summaries for Bilibili, b23.tv, and YouTube videos by extracting metadata and subtitles/transcripts first, then having Codex write the summary and detailed notes. Use when the user asks to summarize, outline, extract key points from, or prepare notes for Bilibili/B-site/BV videos, b23.tv short links, or YouTube videos, especially when they want a local .md document.

# Bilibili Video Summary

Use this skill when the user gives a Bilibili, b23.tv, or YouTube video URL and asks for a summary, notes, outline, timeline, key points, or a local Markdown document. By default, create a local Markdown file unless the user explicitly asks for chat-only output.

## Workflow

1. Run the helper script to extract metadata and subtitles/transcripts to JSON.
2. Read the JSON output.
3. If `items[0].has_transcript` is true, use `items[0].transcript` to write the requested summary yourself.
4. If `items[0].has_transcript` is false for a Bilibili video, use the browser subtitle fallback before audio transcription:
   - Open the video page in the browser.
   - Start playback if needed.
   - Open the player subtitle menu, usually labelled `Subtitle`, `CC`, or Chinese `Zi Mu`.
   - Select a Chinese subtitle track when available, especially `Chinese AI` or `Zhongwen AI`.
   - Confirm that the player shows a message equivalent to "subtitles switched to Chinese".
   - Extract visible subtitle text from the page while the video plays, deduplicate repeated lines, and use the collected text as the transcript.
   - Mark the transcript source as `browser subtitle fallback` in the local Markdown file.
5. If the API, yt-dlp, and browser subtitle fallback all fail, use audio transcription with `--transcribe-audio`.
6. Save a local `.md` file by default. Include source URL, title, channel, duration, transcript source, summary, and detailed notes.
