pptx-posters
Create and audit editable scientific posters in macro-free PowerPoint (.pptx) from author-approved local content and assets. Use when the requested deliverable is a PowerPoint research/conference poster and exact physical, printer, accessibility, provenance, and package-security checks are required.
Why this skill is useful
Adds specific validation and generation procedures for creating compliant PowerPoint posters that the AI wouldn't reliably generate on its own.
What it needs
Requires lxml, pillow, python, python-pptx installed locally. About 6k tokens when loaded. Last updated 2026-08-03. 32,849 stars on the source repository.
What this skill does
PPTX posters Scope Use this skill only when the requested source/deliverable is an editable PowerPoint poster. Do not route an unspecified poster request here merely because PowerPoint is available. Version 2.0 generates a real one-slide .pptx from strict local JSON. It does not use HTML conversion, external templates, schematic/image-generation services, API keys, environment files, network requests, or mandatory figure styles. Hard gates Stop instead of guessing when any gate is unmet: 1. The author has not supplied exact poster content and source records. 2. Any claim, number, citation, author, affiliation, funding statement, figure, license, or QR target is unresolved. 3. Current conference and printer requirements are not confirmed. 4. Author approval is not bound to the current manifest content hash. 5. An asset is remote, outside the manifest directory, unhashed, or unapproved. 6. An input is .pptm, contains macros/external relationships/OLE/embedded files, or is an untrusted template. 7. The requested workflow needs PowerPoint to be opened or executed automatically. 8. A script reports a package, layout, DPI, contrast, or output-plan blocker. Never fabricate missing material or leave a plausible placeholder. Drafts fail closed. Install exact generation dependencies From the skill directory: Generation requires exactly: All CLIs use lazy optional imports, so python -B scripts/<tool>.py --help works without these packages. Use -B to avoid bytecode artifacts. Establish requirements before layout Record these separately: physical trim width/height and orientation; bleed on each edge; safe margin inside trim; PowerPoint canvas width/height; uniform physical-artboard/canvas print scale; conference maximum dimensions and delivery format; printer trim, bleed, margin, scaling, color-mode, and proof requirements; final-output font and raster-DPI thresholds, each labeled as a heuristic or tied to an exact source. …
