consulting-pptx-skill: pricing, features, alternatives

consulting-pptx-skill is a Claude Code skill for boardroom-quality slides. You load a written rulebook, assemble 16:9 HTML sections, run a checker, then print PDF from Chrome. The repo carnot-tech/consulting-pptx-skill is HTML plus Python, created 2026-09-02, MIT. On 2026-09-19 GitHub listed 466 stars and 40 forks. 466 stars is a heat signal, not traffic. A first-party note is on note.com.

It is not a PowerPoint theme pack. Output is HTML (one <section> per slide) and a Chrome PDF. A PPTX sample book exists for people who still need Office. Compare PPTX Posters if you wanted a research poster, or Agent Skills for a broader pack.

The README calls references/slide-rules.md about 110 items. SKILL.md says about 80. Open the file. Do not quote either number as audited.

Key Features

Rule file first: titles carry the conclusion, one message per slide, no rounded corners, no stroke on filled boxes, one term per deck. The agent rereads the file every session because chat memory does not stick.
62 HTML parts: 27 basics (freeform_parts_16x9.html) and 35 extras (freeform_parts_more_16x9.html). scripts/new_deck.py --parts b01,m05,... copies the ones you name.
Machine check: scripts/check_deck.py (stdlib) fails leftover placeholders. Optional scripts/check_layout.mjs needs Playwright for overlap.
Fresh-eye review: references/content-review-prompt.md is for a second agent that does not know the method.
AI-smell list: references/ai-smell-lexicon.md.

Limitation: the checker cannot see a crushed bar chart or a crying line break. You still print PDF and look. Graphs must be drawn, not dumped into a table. The catalog is a layout notebook, not a cage.

Use Cases

Weekly proposals and board packs in Japanese or English consulting style.
Teams that keep adding review comments into slide-rules.md.
Skip if you needed a cinematic promo. Use Bang Motion or video-shotcraft.

Frequently Asked Questions

Does it write a .pptx by default?

No. Default path is HTML to PDF. assets/SuperTemplate_62type.pptx is a sample book.

Must every slide match a catalog type?

No. SKILL.md says pick a type for the story, then drop it if it does not fit.

Why did check_deck warn about an empty title?

Cover, back cover, and chapter doors are allowed to warn. Body slides should not.

Alternatives

PPTX Posters: research posters, not board decks.
Bang Motion: motion HTML that plays like video.
Claude Code: the usual host.

Tips

Write the title column as a story before you pick parts.
Add every review comment as one line in slide-rules.md.
Run a second agent with the content-review prompt after FAIL 0.

Conclusion

consulting-pptx-skill is an open rulebook plus parts plus a checker, not a magic PPTX button. Clone it, read the rules, assemble HTML, and look at the PDF. Skip it when you wanted posters or motion spots.
