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

92%Weight 40%Scale 1-5

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

A well-structured, highly actionable skill body with a clear validated pipeline and clean reference split. The only weakness is minor: a few explanatory prose passages (notably 'Why HTML?') could be tightened to improve token efficiency.

Suggestions

Tighten or remove the 'Why HTML?' paragraph and other rationale asides; the pipeline steps already make the approach self-evident to Claude.

Consider trimming the repeated 'You MUST run open' emphasis to a single concise checkpoint instruction.

Consolidate the Scripts table and the inline per-step script invocations to avoid restating the same run pattern multiple times.

DimensionReasoningScore

Conciseness

The body is dense and task-focused with mostly lean executable content, but the 'Why HTML?' paragraph and a few explanatory asides are minor over-explanation that could be trimmed without loss.

4 / 5

Actionability

Fully copy-paste-ready bash commands with exact flags and viewport sizes, concrete HTML constraints (720pt x 405pt), and specific script invocations cover all common pipeline cases.

5 / 5

Workflow Clarity

A clear 5-step sequenced pipeline with an explicit validation checkpoint ('Fix any errors before proceeding'), mandatory visual-review screenshots, and a troubleshooting table providing error-recovery feedback loops.

5 / 5

Progressive Disclosure

Overview body points via clearly signaled one-level-deep links to real bundle files (three references plus four scripts, all verified present), with heavy detail appropriately offloaded rather than inlined.

Description

100%Weight 40%Scale 1-5

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, specific description that clearly states what the skill does, when to use it with natural trigger terms, and what to avoid. Every dimension lands at the top anchor with no padding or vague language.

DimensionReasoningScore

Specificity

Lists multiple concrete actions (business presentations, quarterly reports, project proposals, roadmaps, training materials) plus the concrete build mechanism (HTML/CSS slides rendered in agent-browser, assembled via PptxGenJS with charts/tables/images), giving comprehensive coverage.

5 / 5

Completeness

Explicitly answers both 'what' (HTML→render→assemble pipeline with native charts/tables/images) and 'when' ('Use this skill any time the user wants to create... from scratch'), plus a 'Do NOT use' boundary clause.

5 / 5

Trigger Term Quality

Comprehensive natural-term coverage including synonyms (PowerPoint presentation, slide deck, pitch deck) and the file extension (.pptx), matching how a user would naturally request this skill.

5 / 5

Distinctiveness Conflict Risk

Clear niche (creating PPTX from scratch via an HTML pipeline) with distinct triggers and an explicit negative boundary excluding editing, format conversion, and extraction, minimizing conflict risk.
