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

100%

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

This is an excellent skill file that efficiently communicates a complex multi-step pipeline for HTML-to-PPTX conversion. It excels in actionability with fully executable commands at every step, maintains strong workflow clarity with explicit validation gates and visual review checkpoints, and uses progressive disclosure effectively by keeping the overview lean while pointing to detailed references. The conciseness is impressive given the complexity of the task — every section earns its place.

Dimension	Reasoning	Score
Conciseness	The content is lean and efficient throughout. It assumes Claude's competence with HTML/CSS, JavaScript, and CLI tools. The brief 'Why HTML?' justification earns its place by explaining the non-obvious architectural choice. No unnecessary explanations of basic concepts.	3 / 3
Actionability	Every step includes exact, copy-paste-ready bash commands and code snippets. The pipeline is fully executable with specific viewport dimensions (960x540), exact file paths, concrete jq commands, and precise agent-browser CLI invocations. Placeholder HTML examples are complete and specific.	3 / 3
Workflow Clarity	The 5-step pipeline is clearly sequenced with explicit validation checkpoints: Step 2 validates HTML and requires fixing errors before proceeding, Step 4 requires visual preview confirmation before PPTX assembly, and the troubleshooting table provides error recovery guidance. The feedback loop (validate → fix → re-validate) is explicit.	3 / 3
Progressive Disclosure	The SKILL.md provides a clear overview with well-signaled one-level-deep references to three specific files (html-rules.md, slide-templates.md, pptxgenjs.md). The main document contains enough actionable content to follow the workflow while appropriately deferring detailed rules, templates, and config formats to reference files.	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.

This is an excellent skill description that covers all key dimensions well. It provides specific trigger terms users would naturally use, clearly defines both what the skill does and when to use it, and explicitly excludes adjacent use cases to minimize conflict with other skills. The only minor note is the use of second person ('Use this skill') in the opening, but the description is otherwise well-structured and comprehensive.

Dimension	Reasoning	Score
Specificity	Lists multiple specific concrete actions and use cases: creating business presentations, quarterly reports, project proposals, product roadmaps, training materials. Also describes the technical pipeline (HTML/CSS rendering, DOM extraction, PPTX assembly with PptxGenJS).	3 / 3
Completeness	Clearly answers both 'what' (create new PowerPoint presentations via HTML/CSS rendering pipeline) and 'when' (explicitly states 'Use this skill any time the user wants to create a new PowerPoint presentation...' and also includes negative triggers with 'Do NOT use this skill for...').	3 / 3
Trigger Term Quality	Excellent coverage of natural terms users would say: 'PowerPoint presentation', 'slide deck', 'pitch deck', '.pptx file', 'business presentations', 'quarterly reports', 'project proposals', 'product roadmaps', 'training materials'. These are all terms users would naturally use when requesting this skill.	3 / 3
Distinctiveness Conflict Risk	Very clearly scoped to creating new PPTX files only, with explicit exclusions for editing, converting, or extracting from existing PPTX files. The 'Do NOT use' clause significantly reduces conflict risk with related presentation skills.	3 / 3
	Total	12 / 12 Passed
