Workflow

Step 0: Pre-check (Chinese Content)

Condition: Only execute if input file contains Chinese text.

Detection:

1. Read input markdown file
2. Check if content contains CJK characters (Chinese/Japanese/Korean)
3. If no CJK content → skip to Step 1

Format Suggestion:

If CJK content detected AND canghe-format-markdown skill is available:

Use AskUserQuestion to ask whether to format first. Formatting can fix:

• Bold markers with punctuation inside causing ** parse failures
• CJK/English spacing issues

If user agrees: Invoke canghe-format-markdown skill to format the file, then use formatted file as input.

If user declines: Continue with original file.

Step 1: Confirm Theme

Before converting, use AskUserQuestion to confirm the theme (unless user already specified):

Step 2: Convert

Step 3: Report Result

Display the output path from JSON result. If backup was created, mention it.
