  "Review the subtitles against the audio, especially names and numbers."

 "agent_prompt": "Use the repo at https://github.com/bilibili/Index-Translate. Follow inference/echo-s2tt/README.md to translate the speech file at <audio_path> from zh to <target_language> and return the subtitle output. Verify that the target language is one of en, ja, or es and that subtitles follow the speech order.",
