pptx

Read, create, or edit PowerPoint .pptx decks — build slides from an outline, extract slide text/speaker notes, edit shapes/tables/charts, replace images, or export to PDF/images. Use whenever a .pptx (or .ppt) file is an input or output, or the user mentions a deck, slides, or a presentation.

Quality

Content

90%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 tight, highly actionable single-file skill with executable examples across read/create/edit/export and a corruption-aware OOXML section. Its main gaps are the absence of inline validation checkpoints within the create/edit flows and no progressive disclosure to separate reference files for the advanced material.

Suggestions

Add an inline validation checkpoint (e.g. reopen and assert) at the end of the 'Create from an outline' and 'Edit existing' sections, not only in the consolidated 'Verify before done' section.

Consider moving the 'Advanced: raw OOXML' section into a references/ADVANCED.md file and linking to it, so the main body stays a lean overview.

Make the export/verify loop explicit as numbered steps (render → inspect → fix → re-render) to reach the top workflow-clarity anchor.

DimensionReasoningScore

Conciseness

Lean and dense throughout: a brief mental model plus executable code, assuming Claude's competence without explaining what a presentation or library is; every section earns its place.

5 / 5

Actionability

Provides fully executable, copy-paste-ready Python and bash for every common case (read/extract, create from outline, edit runs, image swap, tables, charts, export, zip surgery), covering the common cases concretely.

5 / 5

Workflow Clarity

Clear sectioned flow with a dedicated 'Verify before done' step, visual-inspection feedback loop, and an OOXML invariants checklist; however the create/edit flows lack inline numbered validate-fix-retry checkpoints, keeping it just below a 5.

4 / 5

Progressive Disclosure

Well-organized with clear section headers in a single self-contained file; no bundle references exist, and the lengthy Advanced OOXML section could arguably be split into a reference file, leaving minor organization gaps versus a clean one-level-deep reference structure.

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, third-person description that concretely enumerates capabilities and provides explicit, natural-language trigger guidance with file extensions and synonyms. It hits every completeness and specificity anchor with no fluff.

DimensionReasoningScore

Specificity

Lists multiple concrete actions ('build slides from an outline, extract slide text/speaker notes, edit shapes/tables/charts, replace images, or export to PDF/images'), giving comprehensive coverage of the skill's capabilities.

5 / 5

Completeness

Explicitly states both what it does (read/create/edit with enumerated actions) and when to use it ('Use whenever a .pptx (or .ppt) file is an input or output, or the user mentions a deck, slides, or a presentation').

5 / 5

Trigger Term Quality

Covers file extensions ('.pptx (or .ppt)') and natural user terms ('a deck, slides, or a presentation'), matching the anchor for comprehensive keyword coverage including synonyms and extensions.

5 / 5

Distinctiveness Conflict Risk

Targets a clear niche (PowerPoint decks) with distinct, file-extension-based triggers and natural synonyms, minimizing overlap with other skills.
