Translate English text files (.txt, .md) to Chinese for language learning and translation practice. Use when the user asks to translate a text file to Chinese, create a Chinese version of an English document, or generate bilingual materials for translation training. The translation preserves sentence structure and combines broken sentences into complete lines.

Convert English .txt articles into a JSON array of sentence-level English/Chinese (zh) pairs. Translate English into Chinese and generating bilingual {en, zh} entries via the model (no external translation API), then saving to a JSON file.

Clean and reorganize transcript .txt files for clearer English grammar, punctuation, and paragraph flow. Use when asked to fix line breaks, merge fragments into sentences, normalize punctuation, or produce a reflowed transcript saved as a new file.

Generate chapter clips from YouTube videos with yt-dlp and ffmpeg. Use when asked to download YouTube videos/subtitles, generate fine-grained chapters, cut precise clips, or generate per-chapter English SRTs.
