description: Build a complete but efficient Nature-style Chinese PPTX presentation from a scientific paper, preprint, PDF, article text, abstract, figure legends, or reading notes. Use this skill whenever the user asks to make slides/PPT/PPTX for journal club, group meeting, paper sharing, thesis seminar, lab meeting, department report, or academic presentation from a research paper, not only medical papers. It identifies the paper type and argument, selects only the figures needed for the story, writes Chinese slide content and speaker notes, creates the actual .pptx deck, and runs an explicit self-review/corrective revision loop focused on figure quality, text overflow prevention, and non-template visual design before delivery.

Purpose

Transform a scientific paper or paper-derived notes into a complete Chinese, figure-integrated PPTX presentation package with a Nature-style reporting logic.

The skill must not stop at an outline or script. The expected end product is a real .pptx deck. Keep supporting files minimal unless the user asks for more traceability.

Use this skill for papers across scientific fields, including:

• life sciences and medicine
• chemistry and materials science
• environmental and earth sciences
• physics and engineering
• computational biology, AI, and methods papers
• interdisciplinary Nature-family style research
• reviews, perspectives, resources, datasets, and benchmark papers

Core Principle

Use the paper's scientific argument as the presentation spine.

The default slide logic should help the audience answer, in order:

1. Why does this problem matter?
2. What gap or bottleneck does the paper address?
3. What did the authors do?
4. What is the key evidence?
5. Why should we trust the result?
6. What is new, reusable, or broadly meaningful?
7. Where are the boundaries and open questions?

This is more important than copying the paper section order.

Lean Operating Mode

Default to the lowest-overhead workflow that still produces a usable PPTX.

Do:

• read only the source material needed to understand the paper's argument,
• extract only figures/tables that will actually appear in the deck,
• create the PPTX as the primary deliverable,
• design slides with varied, evidence-led composition rather than rigid AI-looking card templates,
• prevent text overflow by writing shorter on-slide copy, using larger text boxes, and splitting slides when needed,
• run at least one self-audit and correction pass on the generated PPTX,
• run lightweight structural checks on the PPTX package after revision,
• write a short QA report.

Avoid by default:

• exhaustive extraction of every figure, page, image, table, or supplement,
• full OCR unless normal text extraction fails or the PDF is scanned,
• saving full raw extracted paper text unless it is needed for debugging or reuse,
• installing new dependencies when an existing tool can complete the task,
• launching GUI apps or desktop automation just to render previews,
• generating long markdown scripts when the user only needs a deck,
• rendering every slide when no reliable headless renderer is available.

Toolchain Policy

Use a cross-platform Python-first stack unless the user explicitly asks for something else:

• PyMuPDF for metadata, text extraction, page rendering, and page-level crops,
• Pillow for figure crops, contact sheets, and lightweight preview images,
• python-pptx for slide authoring and PPTX-safe editing,
• zipfile plus a reopen pass through python-pptx for package validation.

This stack must work on macOS, Linux, and Windows. Use pathlib paths, project-local output directories, and Office-safe fonts or theme fonts. Do not hardcode OS font paths or platform-specific file locations. If Python packages are missing, create a local virtual environment and install the minimum packages only when policy permits; do not install broad document suites just to finish a normal deck.

Treat LibreOffice/soffice as optional, only when it is already available and a real rendered preview is worth the cost. Avoid Keynote, PowerPoint desktop automation, AppleScript, Preview, Finder, open, and any OS-specific font or path dependency in helper scripts. If a preview can be made from extracted slide objects or assets, prefer that over re-rendering the whole deck.

Ask or document the tradeoff before doing expensive extras such as full supplementary-material processing, high-resolution recreation of many figures, full slide-by-slide rendered QA, or very long decks.

Accepted Inputs

The skill may receive:

• a full paper PDF
• supplementary figures or tables
• Word or markdown converted paper text
• abstract + results + figure legends
• structured reading notes
• manually pasted article content
• an input/source.md file
• a user-provided PPTX template

Default output language is simplified Chinese unless the user requests otherwise. Preserve important technical terms, abbreviations, gene/protein names, model
