pptx

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.

Quality

Content

77%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.

The body is highly actionable with executable commands and a strong QA feedback loop, but it loses points on conciseness due to an oversized design-guidance block and on progressive disclosure because two referenced guide files are missing from the bundle.

Suggestions

Add the missing editing.md and pptxgenjs.md referenced in the Quick Reference and workflow sections, or remove the dead links, so navigation resolves.

Move the Design Ideas section (color palettes, font pairings, Avoid list) into a separate references file and link to it from SKILL.md to reduce inlined bulk.

Trim the color palette and font-pairing tables to a few representative examples each, keeping the 'don't default to blue / don't repeat layouts' principles that Claude can't derive.

Dimension	Reasoning	Score
Conciseness	The operational sections are lean and assume Claude's competence, but the large Design Ideas block (10 color palettes, 8 font pairings, a long Avoid list) is taste guidance that could be tightened or moved out, pulling this below the 'minor over-explanation' anchor.	3 / 5
Actionability	Provides copy-paste executable commands throughout — markitdown, thumbnail.py, office/unpack.py, soffice.py, pdftoppm, grep patterns, and install commands — covering read/edit/create/convert/QA cases concretely.	5 / 5
Workflow Clarity	Sequences the editing flow and includes an explicit QA verification loop (generate → inspect → list issues → fix → re-verify → repeat, with 'do not declare success until a fix-and-verify cycle') plus validation checks, matching the feedback-loop anchor for document manipulation.	5 / 5
Progressive Disclosure	Good sectioning and a Quick Reference routing table, but the referenced editing.md and pptxgenjs.md do not exist in the bundle (dead navigation links) and the sizable Design Ideas section is inlined content that could live in its own reference file.	3 / 5

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.

The description is exemplary: it comprehensively lists concrete capabilities, supplies natural trigger terms with the file extension, and explicitly covers both what and when with clear .pptx-specific triggers that minimize conflict risk.

Dimension	Reasoning	Score
Specificity	Enumerates many concrete actions across input/output/both — creating decks/presentations, reading/parsing/extracting text, editing/modifying/updating, combining/splitting, templates/layouts/speaker notes/comments — giving comprehensive coverage rather than just several actions.	5 / 5
Completeness	Explicitly answers both what (the enumerated capabilities) and when ("Trigger whenever the user mentions 'deck,' 'slides,' 'presentation,' or references a .pptx filename") with concrete trigger phrases.	5 / 5
Trigger Term Quality	Includes natural user-facing terms with synonyms and the file extension — "deck," "slides," "presentation," "pitch decks," ".pptx file," and ".pptx filename" — matching the comprehensive anchor.	5 / 5
Distinctiveness Conflict Risk	Scoped tightly to .pptx with niche-specific triggers (deck/slides/presentation/.pptx), making conflict with other skills minimal.	5 / 5
