reading-hub

Mine reusable English chunks from a reading-hub post into the frontmatter `chunks:` YAML used for inline highlights. Use after a post body exists, when the user says "挖语块", "mine chunks", "生成 chunks", or asks for learn-while-reading annotations.

Create reading-hub posts from YouTube videos, web article URLs, pasted text, existing markdown, or user drafts. Use when the user wants to add/archive/save content as a reading-friendly article, says "turn this into a post", "发到 reading-hub", "转成朗读文章", "加一篇文章", or provides a source and asks for a reading post. Writes `src/content/posts/<slug>.md` with Astro-valid frontmatter and source-faithful body content.

Minimal YouTube download + subtitle utilities used by the post-creator skill. Downloads videos and VTT subtitles via yt-dlp, and converts auto-generated VTT captions into sentence-level SRT suitable for shadow reading or downstream transcript processing. Trigger when another skill needs to fetch a YouTube video or flatten its captions into readable sentences.
