pptx

Read, edit, or create PowerPoint .pptx files. Trigger this skill whenever the user mentions a deck, slides, slide deck, presentation, or a `.pptx` filename — whether the goal is to extract text, modify an existing deck, build one from scratch, or prepare slides for review. Three execution paths are supported: text extraction (always available), template editing (unzip → patch slide XML → repack), and creation from scratch (python-pptx for Python or PptxGenJS for Node).

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.

The body is a strong, action-oriented skill: executable recipes for each path, a clear routing decision table, and proper validation/feedback loops for the risky XML and rendering steps. It is only slightly verbose in the design-checklist and troubleshooting sections, which keeps conciseness just below top.

Suggestions

Trim the Design checklist rationale and Troubleshooting prose to imperatives; move OS-by-package install detail into a reference file or the frontmatter install block to save tokens.

Consider relocating the Common pitfalls table into references/ so the SKILL.md body stays a lean overview, keeping only the highest-frequency pitfalls inline.

The PptxGenJS MODULE_NOT_FOUND troubleshooting paragraph is long and prescriptive; condense to the essential rule (disposable local install, no globals) and link out for the rest.

Dimension	Reasoning	Score
Conciseness	Mostly lean and executable with code front-and-center, but the design checklist, pitfalls table, and troubleshooting prose carry some explanatory material that could be trimmed without loss.	4 / 5
Actionability	Provides copy-paste-ready, executable code and commands for every path (extraction, run-level text edits, unzip/repack XML patching, python-pptx creation, PptxGenJS creation) plus concrete thumbnail-rendering invocation.	5 / 5
Workflow Clarity	A clear A/B/C decision table with sub-strategies and explicit validation checkpoints, including a LibreOffice headless validate step and a render→inspect→fix→re-render feedback loop for the destructive XML and visual-QA workflows.	5 / 5
Progressive Disclosure	The body is a well-signaled overview that pushes detail into real, one-level-deep references (references/python_pptx.md, references/pptxgenjs.md) and helper scripts (extract_text.py, render_thumbs.sh) invoked via {baseDir}.	5 / 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 states concrete capabilities, enumerates natural trigger terms including the file extension, explicitly covers both what and when, and is tightly scoped to .pptx with negligible conflict risk. Third-person voice is used throughout with no first/second person.

Dimension	Reasoning	Score
Specificity	Names concrete actions (read/edit/create, extract text, modify a deck, build from scratch, prepare slides for review) plus three specific execution paths (unzip→patch XML→repack, python-pptx, PptxGenJS), giving comprehensive coverage.	5 / 5
Completeness	Explicitly answers both 'what' (read/edit/create plus the three paths) and 'when' ('Trigger this skill whenever the user mentions...'), with concrete trigger phrases.	5 / 5
Trigger Term Quality	Covers natural synonyms users would say ('a deck, slides, slide deck, presentation') together with the '.pptx' filename extension, giving comprehensive natural-term coverage.	5 / 5
Distinctiveness Conflict Risk	Scoped tightly to PowerPoint .pptx with deck/slide/presentation/.pptx triggers, occupying a clear niche with minimal overlap with other skills.	5 / 5
	Total	20 / 20 Passed
