Workflow

1. Parse Arguments

Extract from user input:

pdf_path: Full path to the PDF file (required)
voice_id: Voice identifier (optional)

2. Read PDF Content

Read: file_path = <pdf_path>

3. Extract Text & Metadata

Extract readable text, skipping page numbers and headers. Keep chapter titles, body text, dialogue.

Extract metadata for file naming:

Story Name: Extract from the PDF's parent directory name (e.g., /path/我的世界/chapters/file.pdf → 我的世界)
Chapter Number: Extract from filename pattern *-XX.pdf or content like 第X章 (e.g., 我的世界-03.pdf → 03)
Chapter Title: Extract from the first chapter heading in content (e.g., 第3章：迷宫里的真心话 → 迷宫里的真心话)

4. Select Voice

If voice_id provided: Use the specified voice.

If voice_id not provided: Auto-select based on content keywords:

Content Keywords	Voice ID
童话、儿童、小朋友、冒险	`Chinese (Mandarin)_Cute_Spirit`
言情、爱情、浪漫、甜蜜	`Chinese (Mandarin)_Sweet_Lady`
科幻、悬疑、历史、战争	`Chinese (Mandarin)_Gentleman`
新闻、报告、公告	`Chinese (Mandarin)_News_Anchor`

For complete voice list, see references/voices.md.

5. Convert to Audio

mcp__MiniMax__text_to_audio:
  text: <extracted_text>
  voice_id: <selected_voice_id>
  output_directory: <audiobook subdirectory in story folder>
  language_boost: "Chinese"
  speed: 1

6. Rename Output File

After MiniMax generates the MP3, rename it to follow the naming convention:

<STORY_NAME>_<CHAPTER_NUMBER>_<CHAPTER_TITLE>.mp3

Examples:

我的世界_03_迷宫里的真心话.mp3
文明的最后一个变量_01_第一次接触.mp3

Rename command:

mv "<generated_file>.mp3" "<output_directory>/<STORY_NAME>_<CHAPTER_NUMBER>_<CHAPTER_TITLE>.mp3"

7. Output

Report the final MP3 path with the properly formatted filename.
