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

html-presentation 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HTML Presentation Skill

Convert documents, outlines, or freeform content into polished, self-contained HTML slide presentations with keyboard and scroll navigation.

When This Skill Triggers

  • User provides a document and asks for a "presentation", "slides", or "deck" as HTML
  • User asks to convert notes/outline/content into browser-presentable slides
  • User wants a Reveal.js or scroll-based HTML presentation
  • User references wanting to present from a browser rather than PowerPoint

Step 0: Gather Requirements

Before generating anything, check whether the user has specified the following. If any are missing, ask for clarification in a single concise message. Do NOT ask more than once — use sensible defaults for anything the user declines to specify.

Required context (ask if missing):

Parameter What to ask Default if not specified
Navigation mode "Should slides go left-to-right (horizontal) or top-to-bottom (vertical scroll)?" horizontal
Theme "Which visual style? Options: dark-editorial (dark bg, serif headlines, editorial feel), light-minimal (clean white, sans-serif), corporate (navy/white, professional), hacker (terminal green-on-black, monospace)" dark-editorial
Audience & tone "Who is this for? (e.g., investors, engineers, conference talk, internal team)" Infer from content
Slide count preference "Roughly how many slides?" Auto-determine from content density
Branding "Any logo text, tagline, or accent color to use in the header?" None
CTA / closing "Any call-to-action, links, or contact info for the final slide?" None

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.
