Scientific Critical Evaluation and Peer Review
Overview
Peer review is a systematic process for evaluating scientific manuscripts. Assess methodology, statistics, design, reproducibility, ethics, and reporting standards. Apply this skill for manuscript and grant review across disciplines with constructive, rigorous evaluation.
When to Use This Skill
This skill should be used when:
Conducting peer review of scientific manuscripts for journals
Evaluating grant proposals and research applications
Assessing methodology and experimental design rigor
Reviewing statistical analyses and reporting standards
Evaluating reproducibility and data availability
Checking compliance with reporting guidelines (CONSORT, STROBE, PRISMA)
Providing constructive feedback on scientific writing
Visual Enhancement with Scientific Schematics
When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.
If your document does not already contain schematics or diagrams:
Use the scientific-schematics skill to generate AI-powered publication-quality diagrams
Simply describe your desired diagram in natural language
Nano Banana Pro will automatically generate, review, and refine the schematic
For new documents: Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.

Presentations and Slide Decks
⚠️ CRITICAL: For presentations, NEVER read the PDF directly. ALWAYS convert to images first.
When reviewing scientific presentations (PowerPoint, Beamer, slide decks):
Mandatory Image-Based Review Workflow
NEVER attempt to read presentation PDFs directly - this causes buffer overflow errors and doesn't show visual formatting issues.
Read and inspect EACH slide image file sequentially
Document issues with specific slide numbers
Provide feedback on visual formatting and content
Print when starting review:
[HH:MM:SS] PEER REVIEW: Presentation detected - converting to images for review
[HH:MM:SS] PDF REVIEW: NEVER reading PDF directly - using image-based inspection

Example Image-Based Review Process
[14:30:00] PEER REVIEW: Starting review of presentation
[14:30:05] PEER REVIEW: Presentation detected - converting to images
[14:30:10] PDF REVIEW: Running pdf_to_images.py on presentation.pdf
[14:30:15] PDF REVIEW: Converted 25 slides to images in review/ directory
[14:30:20] PDF REVIEW: Inspecting slide 1/25 - title slide
[14:30:25] PDF REVIEW: Inspecting slide 2/25 - introduction
...
[14:35:40] PDF REVIEW: Inspecting slide 25/25 - acknowledgments
[14:35:45] PDF REVIEW: Completed image-based review
[14:35:50] PEER REVIEW: Found 8 layout issues, 3 content issues
