PPTX Author

pptx-author

Use this skill when running headless and you need to deliver a Chinese market research PowerPoint deck as a file artifact rather than editing a live document through an Office integration.

Output contract

• Write to ./out/<name>.pptx. Create ./out/ if it does not exist.
• Return the relative path in your final message so the orchestration layer can collect it.

How to build the deck

Write a short Python script and run it with Bash. Use python-pptx:

from pptx import Presentation
from pptx.util import Inches, Pt
from pptx.dml.color import RGBColor
from pptx.enum.text import PP_ALIGN, MSO_ANCHOR

prs = Presentation("./templates/firm-template.pptx")  # if a template is provided
# or: prs = Presentation()

slide = prs.slides.add_slide(prs.slide_layouts[5])    # title-only

# Set Chinese-friendly font
def set_chinese_font(run, font_name="微软雅黑", font_size=18, bold=False):
    font = run.font
    font.name = font_name
    font.size = Pt(font_size)
    font.bold = bold
    # For CJK fallback on non-Windows systems
    run._element.set("lang", "zh-CN")

title = slide.shapes.title
for paragraph in title.text_frame.paragraphs:
    paragraph.clear()
    run = paragraph.add_run()
    run.text = "A股新能源汽车行业深度"
    set_chinese_font(run, "微软雅黑", 28, bold=True)

# ... add tables / charts / text boxes with set_chinese_font() ...

prs.save("./out/china-sector-primer.pptx")

Chinese context conventions

• Fonts: Default to 微软雅黑 (Microsoft YaHei) or SimHei for Chinese text; Times New Roman for English words and numbers. If the target system may lack 微软雅黑, fall back to SimHei or specify a system-available CJK font.
• Language: Slide titles and body text may be written in Chinese. Keep titles punchy and takeaway-oriented.
• Numbers and units: Use Chinese market conventions — e.g., 亿元人民币, 万亿元, 个百分点, PE(TTM), PB(LF).
• Content conventions (mirror the live-Office skill but for Chinese research reports):
  • One idea per slide. Title states the takeaway; body supports it.
  • Every number traces to the model. If a figure comes from Tushare, footnote the interface and date, e.g., 数据来源: Tushare daily_basic 2024-12-01. If from a local workbook, cite the path and cell, e.g., 见 ./out/comps.xlsx Sheet1 B7.
  • Use the firm template when one is mounted at ./templates/; otherwise default layouts.
  • Charts: Prefer embedding a PNG rendered from the model over native pptx charts when fidelity matters. Save the PNG to ./out/ and insert it with slide.shapes.add_picture().
  • No external sends. This skill writes a file; it never emails or uploads.

When NOT to use

If mcp__office__powerpoint_* tools are available (Cowork plugin mode), use those instead — they drive the user's live document with review checkpoints. This skill is the file-producing fallback for headless runs.
