1. Template Placement: Put the

   .pptx

   file into the

   ppt_template/

   directory
2. Run Style Extraction: Execute the following command under the skill root directory:

   python scripts/analyze_pptx.py ppt_template/xxx.pptx reference/style-custom.md

3. Read

   reference/style-custom.md

   as the "custom style" to proceed

• Thesis Defense: If the user only has the full paper: first call the "structured information extraction" of paper-write; if structured information is already provided: extract [Paper Title], [Discipline Direction], [Defense Duration], [Paper Structure/Table of Contents], [Core Content of Each Chapter], [Innovation Points/Contributions], etc. from the message, ask for missing information if any
• General Presentation: Extract slide outline and content from user messages, or expand to complete structure based on core requirements

Each reference/styleX-*.md only defines style and layout (color, font, component layout), and no longer defines the page order repeatedly; if you need to modify the default page order, you should adjust it uniformly in this SKILL.

• Recommended Naming (Generation/Export Stage): Prioritize ASCII file names (English letters/numbers/hyphens) to reduce problems such as garbled Chinese file names and files not found by commands in PowerShell/encoding environments.
  • Recommended:

    defense-style4-tech.drawio

    ,

    defense-style4-tech.pptx

  • If Chinese name is required: it is recommended to complete the export with ASCII name first, and then rename it to Chinese in the file explorer
• Delivery Order (Recommended Process): Provide

  .drawio

  (source file) first → Execute command to export

  .pptx

  (delivery file) → Verify the number of pages
• Delivery Dependency: The receiver only needs to open

  .pptx

  (attach

  .drawio

  if necessary), no need to install Python; scripts/code are only used for automatic XML writing on the generation side (optional).

1. Multi-page Structure: The root node must be

   <mxfile>

   , and each page has one

   <diagram>

   (otherwise it will be exported as 1 page).
2. Coordinate System per Page:

   x

   starts from 0 in each

   <diagram>

   ; background rectangle

   x=0,y=0,w=1920,h=1080

   ; each page has

   mxCell id="0"

   and

   mxCell id="1" parent="0"

   .
3. Unique ID: All

   mxCell id

   in the entire file must be unique; each

   <diagram id="...">

   must also be unique.
4. One-time Writing:

   .drawio

   must be written completely at one time (do not overwrite/splice XML multiple times).
5. Page Count Verification: The

   (N slides)

   output by

   drawio2pptx

   must be equal to the number of

   <diagram>

   .
6. Cell Count per Page: Cover ≥ 12, section title ≥ 8, content page ≥ 15 (avoid "blank pages").
7. Only use real line breaks for line wrapping: When generating XML, multi-line body text must be written as real line breaks (use

   \n

   to splice in the code, and then write to the file at one time). It is forbidden to write

   


   /

   <br>

   /

   <font>/<b>

   in

   value="..."

   , and it is also forbidden to replace

   


   with literal

   `n

   through Shell; text style must include

   whiteSpace=wrap;html=1;

   .
8. Do not replace white text by mistake: The text in the top bar/dark block keeps

   fontColor=#FFFFFF

   ; when replacing the background color, prioritize modifying

   fillColor

   , do not replace all

   #FFFFFF

   globally.
9. Occlusion Check: Decorative blocks with background color should not cross the body area; do not place labels with background color between two columns of cards (it will press the text).
10. Height Budget: The card/container for multi-line body text should be rather higher to leave blank space to avoid cutting text (body line height is about (1.4\times) font size).

The writing method must meet the requirements of Item 4 "One-time Writing" and Item 7 "Only use real line breaks for line wrapping" in the checklist.

.drawio

1. If not installed:

   pip install drawio2pptx -q

2. Switch to the directory where the

   .drawio

   file is located (you must cd/Set-Location first, otherwise the file cannot be found):
   powershell

   Set-Location "d:\你的项目目录"
   drawio2pptx <文件名>.drawio <文件名>.pptx

3. Verify the number of output pages: The output must contain

   Saved xxx.pptx (N slides)

   , and (N) is equal to the number of

   <diagram>

   (corresponding to Item 5 "Page Count Verification" in the checklist)

Page count verification must meet the requirements of Item 5 "Page Count Verification" in the checklist.

• Permission denied: The target

  .pptx

  is being occupied by PowerPoint.
  • Solution: Export to a new file name (such as

    *-v2.pptx

    ), or close the PPT first and then overwrite the export.
• Garbled Chinese file name / File not found: Terminal encoding causes abnormal path resolution.
  • Solution: Use ASCII file names for generation and export (see 2.2).

• Unified Font Size Rules (All Styles):
  • Chinese body text on content pages (paragraphs + list points) uniformly use 18 pt;
  • Chapter titles on content pages are generally 30 pt, large numbers/chapter names on section title pages continue to follow the examples in each styleX;
  • Secondary information such as date, footer, small labels, chart headers can keep the existing design between 13–16 pt.
• Font Recommendation: Chinese titles/body text prefer Microsoft Yahei or Song Typeface; numbers, English and formulas use Times New Roman. Each style reference can be fine-tuned on this basis (such as using Georgia for English titles).
• XML tags are closed correctly, special characters are escaped (

  &

  ,

  <

  →

  <

  )
• Page layout: Full canvas background rectangle, title area 44–56pt, body text reserved space according to 18pt line height, sufficient blank space

• tail

  command is not supported under Windows, use PowerShell's

  Select-Object -Last N

  instead for Shell output truncation
