pptx-posters

Create research posters using HTML/CSS that can be exported to PDF or PPTX. Use this skill ONLY when the user explicitly requests PowerPoint/PPTX poster format. For standard research posters, use latex-posters instead. This skill provides modern web-based poster design with responsive layouts and easy visual integration.

Quality

Content

85%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-sequenced skill body with strong validation feedback loops and properly structured one-level-deep references to real bundle files. The main weakness is conciseness: the poster-format readability rules are repeated across four sections and could be consolidated.

Suggestions

Consolidate the poster-format font/element rules (the POSTER FORMAT REQUIREMENTS block, Step 0 checklist, Step 2b checklist, and Common Pitfalls) into a single authoritative section to remove ~40% of the repetition.

Since `assets/poster_quality_checklist.md` already exists, replace the inline Step 0 / Step 2b / After-Export checklists with a brief pointer to that file rather than duplicating them in the body.

Trim the restated "When to Use" / "DO NOT use" guidance that overlaps the frontmatter description and the Overview section to reduce token overhead.

DimensionReasoningScore

Conciseness

The body is roughly 400 lines and restates the same poster-format rules (3-4 elements max, 50% white space, GIANT 100pt+ text) across the font-requirements block, the pre-generation checklist, the post-generation checklist, and Common Pitfalls, which could be tightened considerably; not 1 because it does not explain concepts Claude already knows and the guidance is domain-specific, and not 3 because the repetition is genuine padding.

2 / 3

Actionability

Provides copy-paste-ready executable commands throughout — `mkdir -p figures`, `python scripts/generate_schematic.py "..." -o figures/hero.png`, `cp skills/pptx-posters/assets/poster_html_template.html poster.html`, headless Chrome PDF export, LibreOffice conversion, and a python-pptx example; not 2 because the code is concrete and runnable rather than pseudocode.

3 / 3

Workflow Clarity

A clear five-stage sequence (Planning → Generate Visuals → Create HTML → Export PDF → Convert PPTX) with mandatory validation checkpoints (Step 0 Pre-Generation Review, Step 2b Post-Generation Review with PASS/FAIL criteria, After-Export checklist) and regenerate feedback loops; not 2 because validation is explicit, not implicit.

3 / 3

Progressive Disclosure

Points to real, one-level-deep bundle files that all exist on disk — `assets/poster_html_template.html`, `assets/poster_quality_checklist.md`, and three `references/*.md` guides — with dedicated Template Assets and References sections giving one-line descriptions; not 2 because references are clearly signaled and not nested.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, well-scoped description that states concrete capabilities, includes natural trigger terms, gives an explicit use-when clause, and clearly disambiguates from the latex-posters default. The ONLY-when-PPTX framing makes conflict risk low.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "Create research posters using HTML/CSS that can be exported to PDF or PPTX" and "web-based poster design with responsive layouts" — matching the multiple-specific-actions anchor; not 2 because it goes beyond naming a domain plus partial actions.

3 / 3

Completeness

Explicitly answers both what ("Create research posters using HTML/CSS that can be exported to PDF or PPTX") and when ("Use this skill ONLY when the user explicitly requests PowerPoint/PPTX poster format"); not 2 because the trigger is explicit rather than merely implied.

3 / 3

Trigger Term Quality

Uses natural terms a user would actually say — "PowerPoint/PPTX poster format" and "research posters" — giving good coverage rather than just technical jargon; not 2 because common variations (PowerPoint, PPTX, research poster) are all present.

3 / 3

Distinctiveness Conflict Risk

Carves a clear niche by restricting to explicit PPTX requests and routing standard posters to latex-posters, making wrong-skill triggering unlikely; not 2 because the boundary against the sibling skill is explicitly stated.
