⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 28, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.
Built the same consulting-style comparison table twice - 58 lines of hand-written python-pptx as the no-skill baseline, then a 30-line YAML spec through pptx generate - and rendered both to PNG with the bundled renderer. The baseline came out with a dead 1.5-inch empty header band and equal-height rows padded with whitespace; the skill's slide auto-fit every row height to its content, rendered inline bold inside cells, and picked up the template's tracker, header rules and page number. The documented JSON edit round-trip held up too: font, size and bold survived pptx edit intact, though handing edit a plain string containing markdown stores the asterisks literally and merges the runs. Setup cost is real - pip install -e . from the clone, and pptx render additionally needs LibreOffice (soffice) on PATH. Its description also says 'generate PowerPoint slides' without mentioning it only generates table slides, so it will load for pitch-deck requests it cannot serve.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 4/5
- Output vs. baseline 8/10
- Docs & honesty 4/5
What Clean Slides does
A pptx CLI that turns a YAML spec into a dense, consulting-style table slide, handling column widths, row heights, font sizing, dividers and bullet hierarchy automatically. It also inspects existing decks shape by shape, edits text through a JSON round-trip that keeps run-level formatting, inserts or deletes slides, and renders slides to PNG for visual checking. Triggers when someone asks to build, inspect, edit or render a .pptx file.
How to install Clean Slides
Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
Commands — how to trigger Clean Slides
-
/clean-slidesConsulting-style PowerPoint tables from YAML, with PNG render verification
It also activates on plain-language prompts like these:
-

Edit the text on slide three of this deck without breaking formatting -
Render slide eight of deck.pptx to PNG so I can check the alignment
Frequently asked questions
- Is the Clean Slides skill free?
- Yes. The skill itself is free from tmustier/clean-slides. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Clean Slides work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Jul 28, 2026. Verdict: Tested · Works.

- What is the Clean Slides SkillProof Score?
- 8.4/10 — installs cleanly 5/5, triggers reliably 4/5, output vs. baseline 8/10, docs & honesty 4/5.
- How do I install Clean Slides?
- Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
- Can I use Clean Slides with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
- The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
