Conciseness

The body is dense and operational — tool tables, decision tables, and pitfall comments (LAYOUT_WIDE vs LAYOUT_16x9 coordinate mismatch, CJK fontFace) with no re-teaching of concepts Claude already knows. Falls at 4 rather than 5 because demo 2.2 substantially duplicates 2.1's generation pattern (same addText/master/layout scaffolding) and could be trimmed or merged; not 3 since there is no padding or unnecessary explanation elsewhere.

Actionability

Fully executable, copy-paste-ready code throughout: complete pptxgenjs scripts (masters, KPI shapes, charts, notes), an adm-zip XML patch script, concrete PptxInspect/DocConvert/CloudImageUnderstand invocations with parameters, and a symptom/cause/fix recovery table. Matches the 5 anchor — specific examples cover the common cases (create, generate-from-data, edit, read, convert, visual QA).

Workflow Clarity

Sequencing is clear (numbered Read → Write → Convert sections, a summary→next-step decision table, an error-recovery table, an anti-hallucination checkpoint, and a user-confirm checkpoint for >20-slide batches), which would otherwise merit 4. However the section 2.3 edit workflow destructively overwrites the existing deck.pptx with no backup and no post-edit verification step (e.g., re-inspect or render slide 3 to confirm), so the destructive-operation cap holds it at 3; not 2 because most checkpoints and feedback loops are in fact present.

Progressive Disclosure

No bundle files exist and the body references none, so structure is judged on the inline organization: clear section headers, a tool responsibility table, and well-delimited numbered sections make navigation easy. Scores 4 rather than 5 because ~250 lines are fully inline where the long worked demos (2.1–2.2) could live in an examples reference file, and the under-50-line exception does not apply; not 3 since nothing is buried and the organization is genuinely good.

Specificity

Lists multiple concrete actions — "read, summarize, extract, edit, create, or convert" — covering the full PPTX task space, plus concrete tool-level guidance ("render the target slide(s) as PNG images (via PptxInspect render)"). Matches the 5 anchor (multiple specific concrete actions, comprehensive coverage); not 4 because no meaningful action category is missing.

Completeness

Explicitly answers both what ("read, summarize, extract, edit, create, or convert") and when ("Load this skill whenever the user mentions a .pptx file, deck, slides, or presentation") with concrete trigger phrases. Matches the 5 anchor; not 4 because the 'when' clause is fully explicit, not merely implied or generic.

Trigger Term Quality

Covers natural terms and synonyms comprehensively — "PowerPoint", ".pptx", "PPT", "deck", "slides", "presentation" — and adds verbatim user phrasings ("summarize this PPT", "what's on slide 3", "make me a Q4 report deck"). Matches the 5 anchor including file extensions; not 4 since common variations are all present.

Distinctiveness Conflict Risk

Clear niche scoped to PowerPoint/.pptx with distinct triggers (deck, slides, presentation, slide-N phrasings); no plausible mis-trigger against PDF, Word, or generic document skills. Matches the 5 anchor (clear niche, minimal conflict risk); not 4 because overlap risk is negligible.
