Generating Presentations (Recommended)

For structured presentations with cover slide, auto-generated TOC, content slides, and closing, use the pre-built template:

Step 1: Copy the generator script

cp /builtin-skills/pptx/scripts/generate_report.js ./generate_pptx.js

Step 2: Build slides_data.json via Python script

Two phases: write slide content files, then assemble into JSON.

CRITICAL: NEVER write or edit .json files directly. Use a Python script with json.dump() to guarantee valid JSON output.

Phase 1 — Write each slide's content as a plain text file using write_file:

For each major topic, read_file the relevant research data, then write_file the slide content directly:

read_file("research_data/literature.md")           # refresh data in context
write_file("slides/slide_01_intro.txt", "...")      # write slide body
write_file("slides/slide_02_analysis.txt", "...")   # next slide
...

Each content slide body should be concise but substantive (3-6 bullet points or 2-4 sentences with specific data and citations).

NEVER write a Python script that contains slide text as string literals. The slide content goes directly into .txt files via write_file, not into Python code.

Language (CRITICAL):

• All presentation content (title, subtitle, slide headings, body text, chart labels, speaker notes) MUST be written in the user's configured language as specified in the system prompt's ## Language section.
• If the user's language is Chinese (zh), write the entire presentation in Chinese; if English (en), write in English. Do NOT mix languages unless quoting a proper noun or technical term that has no standard translation.
