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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00041 | $0.00713 |
| Opus 5.5 | $0.00016 | $0.00285 |
| Sonnet 5.5 | $0.00008 | $0.00143 |
| Haiku 4.5 | $0.00004 | $0.00071 |
Grade A, and why
presentation-viewer 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 2mo 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Presentation Viewer
Build a single self-contained viewer.html from a folder of markdown slide files.
When to use this skill
The user has a folder of numbered markdown files (e.g. slide00.md, slide01.md, …) and wants a browser-based slide deck generated from them.
Inputs
- Slide folder — path to the directory containing markdown slides (default:
presentation/). - Output path — where to write
viewer.html(default: project root). - Presentation title — used for the HTML
<title>tag, extracted from the first# headingin slide 00 if not specified.
Steps
1. Discover slides
- List the slide folder.
- Collect all
.mdfiles, sorted in natural order (slide00, slide01, … slide99, then any non-numbered files likesources.mdlast). - Read every file's full content.
2. Extract titles for the slide picker
For each slide, derive a short title:
- Use the first
# headingtext in the file. - If index is known, prefix with the number:
"0 — Title","1 — The Problem", etc. - For non-numbered files, use the heading alone:
"Sources & Further Reading".
3. Generate viewer.html
Produce a single HTML file following the exact template in template.html (in this skill folder). The only things that change between presentations are:
| Placeholder | What to insert |
|---|---|
{{TITLE}} |
Presentation title for the <title> tag |
{{SLIDES_JS}} |
One slides.push(\…`);call per slide, with the raw markdown embedded as a JS template literal (backtick-delimited). Escape any backticks in the markdown as\`and any${as${`. |
{{TITLES_JS}} |
The const titles = [...] array of picker labels. |
Do NOT modify the CSS, the JavaScript engine, or the CDN imports. The template is the source of truth.
4. Verify
After creating the file, confirm:
- The file is valid HTML (no unclosed tags).
- Every slide's markdown is present in the JS array.
- The
titlesarray length matches theslidesarray length.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
