PPTX Scientific Poster Builder & Auditor

Builds macro-free, editable PowerPoint conference posters from an author-approved local manifest, with physical-size, printer, accessibility, and package-security audits.

What it does

  • Generates a real one-slide editable .pptx research poster from a strict local JSON manifest — no HTML conversion, external templates, API keys, or network calls.
  • Enforces provenance: source IDs, author_verified flags, local image paths with SHA-256 hashes, licenses, approved alt text, explicit reading order, and visible QR fallback URLs.
  • Binds author approval to a canonical content hash, so any later edit invalidates the sign-off.
  • Preflights effective DPI (pixels ÷ final placed inches), WCAG 2.2 sRGB contrast pairs, fonts, color mode, and printer trim/bleed/CMYK requirements.
  • Ships a non-executing ZIP/XML inspector that rejects macros/VBA, ActiveX, OLE, embedded parts, external relationships, symlinks, and zip-bomb ratios.
  • Layout checker catches overlaps, out-of-bounds shapes, and too-small final font sizes; a manual PowerPoint accessibility gate closes the loop.

Who it's for

  • Grad students and researchers preparing conference posters
  • Lab or comms staff who must hit exact printer and accessibility requirements
  • Teams that need to screen incoming .pptx files for security risks

Example uses

  1. Conference poster build: fill the manifest with final text, figures, and citations → validate_manifest.py --print-content-hash → get PI approval on that hash → generate_poster.py produces poster.pptx plus a generation report.
  2. Pre-print preflight: run inventory_images.py to confirm each figure's effective DPI at its placed size, and check_palette.py to verify contrast and non-color-only encoding before sending to the printer.
  3. Safety screen: run inspect_pptx.py on a poster received from a collaborator to detect macros, OLE objects, or remote linked images without ever opening the file.

  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on AI Skill Mart.
Copy the skills/pptx-posters folder from the GitHub repo K-Dense-AI/scientific-agent-skills into my ~/.claude/skills/pptx-posters/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/K-Dense-AI/scientific-agent-skills.git /tmp/scientific-agent-skills && mkdir -p ~/.claude/skills && cp -r /tmp/scientific-agent-skills/skills/pptx-posters ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and clone the repo: git clone https://github.com/K-Dense-AI/scientific-agent-skills.git
  2. Copy the skill into your Claude skills folder: mkdir -p ~/.claude/skills && cp -r scientific-agent-skills/skills/pptx-posters ~/.claude/skills/
  3. Verify prerequisites: Python 3.10+ and uv (python3 --version, uv --version).
  4. Install the exact pinned dependencies: cd ~/.claude/skills/pptx-posters && uv venv && uv pip install "python-pptx==1.0.2" "Pillow==12.3.0" "lxml==6.1.1"
  5. Restart Claude Code and ask for something like "build my conference poster as an editable PowerPoint file".
  6. Copy assets/poster_manifest_template.json into your project, replace every token with real content, sources, and local image paths, then complete the hash-bound author approval step before generating.
