generate-slides

A command for generating a slide deck as a self-contained HTML page, with an optional attempt to export it to PowerPoint. HTML is the web-page format used by browsers.

In plain words
What is it for?
It helps plan slide content, create an HTML deck with navigation, and produce a best-effort PPTX file when the required export tools are available.
Why use it?
It turns source material into a browser-viewable presentation and makes clear which interactive or responsive features may not survive PowerPoint export.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

generate-slides scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Load the visual-explainer skill and generate a slide deck for: $@

If $@ contains the literal --pptx flag, remove that flag from the topic. Generate the HTML slide deck first, then run the best-effort static exporter with visual-explainer-pptx <deck.html> <deck.pptx> from package installs or node ./pptx/export.mjs <deck.html> <deck.pptx> from a checkout after dependencies are installed. If the exporter dependencies are not available, deliver the HTML deck and explain that PPTX export needs the package install or checkout dependencies. Tell the user that the HTML deck remains the source of truth and the PPTX will not preserve animations, reader navigation, responsive layout, custom fonts, live Mermaid/Chart.js/SVG/canvas rendering, or JavaScript behavior.

Before writing HTML, read ./templates/slide-deck.html, ./references/slide-patterns.md, and only the shared CSS/library sections needed for the source.

Plan the deck first: inventory the source, map every item to slides, choose a narrative arc, and assign a composition to each slide. Use the 10 slide types and nav chrome from slide-patterns.md/slide-deck.html, including carousel dots, prev/next, slide count, and keyboard controls. Treat 100dvh as a hard content budget: split dense content across slides rather than scrolling or dropping content. Before delivery, enable prefers-reduced-motion: reduce at the target viewport and a short landscape height; fix every overflow or autoFit() warning before shipping.

Use visual-first slides: diagrams, charts, tables, SVG accents, and images from surf only when they clarify the story. Vary compositions; three centered slides in a row is a smell.

Write to ~/.agent/diagrams/ and open in the browser.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
