pptx

Use this skill any time the user wants to create a new PowerPoint presentation, slide deck, pitch deck, or .pptx file from scratch. Covers creating business presentations, quarterly reports, project proposals, product roadmaps, training materials, and any multi-slide document destined for PowerPoint. Works by generating HTML/CSS slides (which LLMs excel at), rendering them in agent-browser for pixel-accurate DOM position extraction, and assembling the final PPTX with native PowerPoint charts, tables, and images via PptxGenJS. Includes bundled scripts for validation, DOM extraction, and PPTX assembly. Do NOT use this skill for editing existing PPTX files, converting other formats to PPTX, or extracting content from PPTX files.

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 progressive disclosure and validation feedback loops. Its only weakness is minor verbosity — repeated emphasis on the preview-step and a 'When to Use' section that duplicates the frontmatter description.

Suggestions

Consolidate the 'run open after each screenshot' guidance, which currently appears in a code comment, an 'IMPORTANT' line, and a 'You MUST…Do not skip' line; keep a single bold callout and drop the duplicates.

Trim or remove the 'When to Use' / 'Do NOT use for' section, which restates scope already covered in the frontmatter description, or reduce it to a one-line pointer.

Shorten the 'Why HTML?' rationale to one sentence; the getBoundingClientRect mechanism it introduces is re-explained in Step 3.

Dimension	Reasoning	Score
Conciseness	Mostly efficient and concrete with no basic-concept padding, but it could be tightened: the 'run open after each screenshot' instruction is repeated three times (code comment, an 'IMPORTANT' line, and a 'You MUST…Do not skip' line), and the 'When to Use'/'Do NOT use for' section restates scope already present in the frontmatter description.	2 / 3
Actionability	Provides fully executable commands throughout — 'agent-browser set viewport 960 540', 'cat $SKILL_DIR/scripts/validate.js \| agent-browser eval --stdin --json', and 'node $SKILL_DIR/scripts/build-pptx.js …' — with exact dimensions and concrete placeholder HTML, making it copy-paste ready.	3 / 3
Workflow Clarity	A clear 5-step sequence with an explicit validation checkpoint ('returns { valid: true/false, errors: [...] }', 'Fix any errors before proceeding') and a verification loop (screenshot + open the preview, then 'Once all slides are reviewed, run the bundled build script'), plus a troubleshooting table for error recovery.	3 / 3
Progressive Disclosure	The body is an overview with well-signaled one-level-deep references — [references/html-rules.md], [references/slide-templates.md], [references/pptxgenjs.md], all real files — and a closing 'Reference Files' list, with detail appropriately split out rather than inlined.	3 / 3

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-crafted description: concrete actions, rich natural trigger terms, explicit what-and-when guidance, and clear do-not-use disambiguation. It scores at the top of every dimension with no vague fluff or over-claims.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'generating HTML/CSS slides', 'rendering them in agent-browser for pixel-accurate DOM position extraction', and 'assembling the final PPTX with native PowerPoint charts, tables, and images via PptxGenJS' — matching the anchor for multiple specific concrete actions. Voice is third-person/trigger imperative ('Use this skill any time the user wants…') with no first- or second-person pronoun, so no voice penalty applies.	3 / 3
Completeness	Explicitly answers both 'what' (the HTML→DOM-extraction→PptxGenJS assembly pipeline and bundled scripts) and 'when' ('Use this skill any time the user wants to create a new PowerPoint presentation…'), with an explicit 'Use when'-equivalent trigger so it is not capped at 2.	3 / 3
Trigger Term Quality	Covers natural terms users would actually say — 'PowerPoint presentation, slide deck, pitch deck, .pptx file', 'quarterly reports, project proposals, product roadmaps, training materials' — giving good coverage of common variations.	3 / 3
Distinctiveness Conflict Risk	Has a clear niche (create-from-scratch via the HTML pipeline) and an explicit disambiguation — 'Do NOT use this skill for editing existing PPTX files, converting other formats to PPTX, or extracting content from PPTX files' — making conflict with adjacent skills unlikely.	3 / 3
	Total	12 / 12 Passed
