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.

A well-organized, actionable body with strong QA feedback loops and executable commands. The main defects are broken references to missing detail files (editing.md, pptxgenjs.md) and a heavy inlined design section that would benefit from being split into its own reference.

Suggestions

Add the missing editing.md and pptxgenjs.md files (or remove/repoint the references) so the Quick Reference table and workflow sections resolve to real content.

Move the large Design Ideas section (color palettes, typography pairings, layout options) into a separate reference file (e.g. design.md) and keep a brief pointer in SKILL.md to improve token efficiency and progressive disclosure.

Tighten the editing workflow step 2 ('Unpack → manipulate slides → edit content → clean → pack') into explicit sub-steps with the corresponding script commands inline, since the detail file is currently absent.

Dimension	Reasoning	Score
Conciseness	Mostly lean with no concept-explanation fluff (no 'what is a pptx' padding) and executable commands throughout, though the Design Ideas section is voluminous (10 color palettes, 8 font pairings) and could be trimmed or moved to a reference file.	4 / 5
Actionability	Concrete executable commands throughout ('python -m markitdown', 'python scripts/thumbnail.py', 'python scripts/office/unpack.py', 'pdftoppm -jpeg -r 150', pip/npm installs) and a ready-to-use QA subagent prompt, but the editing/creating-from-scratch detail files (editing.md, pptxgenjs.md) are referenced and missing, leaving a gap in executable guidance for those paths.	4 / 5
Workflow Clarity	Clear sequenced editing workflow plus an excellent QA Verification Loop with explicit feedback checkpoints ('Fix issues → Re-verify affected slides → Repeat until a full pass reveals no new issues') and a guard ('Do not declare success until you've completed at least one fix-and-verify cycle'), matching the anchor for validation with error-recovery loops.	5 / 5
Progressive Disclosure	Good top-level structure (Quick Reference table routing to the three main paths, clearly signaled section references) but two referenced files — editing.md and pptxgenjs.md — do not exist in the bundle, breaking navigation, and the large inlined Design Ideas section is content that could live in a separate file.	3 / 5

Description

95%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, comprehensive description with explicit trigger guidance and broad concrete action coverage. The only issue is second-person voice ('Use this skill'), which per the rubric reduces the specificity score by one point.

Suggestions

Rewrite in third person to avoid the voice penalty — e.g. 'Handles any task involving .pptx files...' instead of 'Use this skill any time...'.

Dimension	Reasoning	Score
Specificity	Lists many concrete actions ('creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text... editing, modifying, or updating... combining or splitting slide files; working with templates, layouts, speaker notes, or comments') for comprehensive coverage, but the second-person imperative 'Use this skill any time' triggers the voice penalty reducing the base 5 by 1.	4 / 5
Completeness	Explicitly answers both what (creating/reading/editing/combining/templates/notes) and when ('Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename... If a .pptx file needs to be opened, created, or touched, use this skill.').	5 / 5
Trigger Term Quality	Comprehensive natural-term coverage including synonyms ('deck,' 'slides,' 'presentation') and the file extension '.pptx', matching the anchor's expectation of synonyms plus extensions.	5 / 5
Distinctiveness Conflict Risk	Clear niche scoped to .pptx files with distinct triggers ('deck,' 'slides,' 'presentation,' '.pptx'), minimal overlap risk with other skills.	5 / 5
