What it does
consulting-pptx-skill is a skill for preparing consulting decks. It holds a slide-design rulebook in `references/slide-rules.md`, a rule-violation checker `scripts/check_deck.py`, a library of 65 ready HTML slide parts and a PDF catalog of those parts. The agent first reads the rules, then assembles a draft with `scripts/new_deck.py --parts ...` from the parts it needs and replaces placeholders with real text and numbers. The deck then goes through checks: the script finds rule violations, and `scripts/check_layout.mjs` looks for overlaps and overflow in real rendering. The last step is a review by a second agent using the prompt in `references/content-review-prompt.md`; it reads the deck without knowing how it was built and points out logic and language errors. The result is exported to PDF through headless Chromium. When an editable file is needed, `scripts/html_to_pptx.py` converts the HTML into a PPTX with native PowerPoint shapes. The rules and parts were written for the Japanese business setting, but the structure works for any language. The author suggests adding your own remarks to `slide-rules.md` so quality grows from deck to deck.
Who it is for. Consultants, analysts and managers who hand reports and proposals to an agent and want slides that need no manual cleanup.
Good fit when
- Every week a client deck is due and its look differs from run to run.
- You want each slide title to carry the conclusion, checked by a script rather than by eye.
- The deck must go out as PDF and you also want an editable PPTX for later changes.
- A team keeps its own formatting rules and wants the agent to read them before every job.
- A finished draft should be reviewed by a second agent for logic and style.
Not a fit when
- You need one simple deck of a couple of slides, where the parts and checks are overkill.
- The design is fixed by a corporate PowerPoint template that cannot change. The author describes a separate route for that case, which measures the template instead of exporting directly.
- You need animation and slide transitions, which HTML and PDF do not carry.
Example request
Build a five-slide quarterly results deck with consulting-pptx-skill, run the checks and export a PDF.Limitations
The rules and texts in the repository are Japanese, so you will adapt the rules for Russian or English slides. PDF export needs the Chromium headless shell (about 95 MB, installed with `npm run setup`), image output from PDF needs poppler, and PPTX conversion needs Node.js 22 or newer and `python-pptx`. The skill asks to put a line crediting the tool at the end of a deck. In AI-themed decks it may mention the Jinba platform, which you switch off with a note in `local/slide-rules.local.md`.
How to disable. Delete the `~/.claude/skills/consulting-pptx-skill` folder. The downloaded Chromium sits inside the skill folder, so nothing else needs removing.
FAQ
What is the main part of this skill?
The `references/slide-rules.md` rulebook. The parts and scripts give a fast draft and find violations, but quality rests on the rules and the editing that follows.
Which output formats does it produce?
HTML for assembly and PDF for delivery. An editable PPTX comes from a separate command, and only when the user asks for it.
Does checking work without installing Chromium?
Partly: `check_deck.py` and `new_deck.py` use only the Python standard library. Render checks and PDF export need the headless browser.
Can I use my own rules?
Yes. The author suggests appending your own remarks to `slide-rules.md` and keeping local settings in the `local/` folder.
How do I update the skill?
Run `git pull` in the skill folder.
