Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00084 | $0.01751 |
| Opus 5 | $0.00042 | $0.00875 |
| Sonnet 5 | $0.00017 | $0.00350 |
| Haiku 4.5 | $0.00008 | $0.00175 |
Grade A, and why
html-deck 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 2d 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 — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HTML deck
A deck is a single HTML file with inline CSS and JS. No build step, no dependencies, no external renderer. It opens in a browser, presents with the keyboard, and exports to PDF.
Source: frontend-slides. See
the plugin's NOTICE.md.
Non-negotiables
- Fixed 16:9 stage. Every slide is authored inside a 1920x1080 stage that is scaled as a whole to the viewport. It may letterbox; it must never reflow. No responsive breakpoints rearranging slide content — a deck looks the same on a phone as on a projector, only smaller.
- Switch slides with visibility, never
display.assets/viewport-base.cssusesvisibility/opacity/pointer-events. A later rule such as.slide-content { display: flex }overridesdisplay: noneand paints every slide at once — a failure that looks like the deck is broken rather than mis-styled. - One file. All CSS and JS inline. Images sit beside it in
assets/, by relative path. - Include
assets/viewport-base.cssin full in the<style>block. Copy it; do not paraphrase it. - Read
${CLAUDE_PLUGIN_ROOT}/shared/design-system.mdbefore choosing type or colour. The rules against the default generated look apply here more than anywhere — a deck is the deliverable people judge on sight.
Phase 0 — what is being asked
- New deck → Phase 1.
- Rework an existing deck → read the file first, then follow Reworking at the bottom. Fit is the risk, not taste.
Phase 1 — content and shape
Ask everything in one go. Use the environment's structured-question UI when there is one; otherwise one message with numbered options.
- Purpose — pitch / teaching / conference talk / internal
- Length — short (5–10) / medium (10–20) / long (20+)
- Content — ready / rough notes / topic only
- Density — see below
- Time budget — how long they have to present it
Density decides the design
| Mode | For | Behaviour |
|---|---|---|
| Speaker-led | Talks, keynotes, anything explained live | One idea per slide, large type, generous space, 1–3 bullets, more slides |
| Reading-first | Handouts, async review, internal detail | Self-contained slides, structured grids and tables, 4–8 bullets or 4–6 cards, tighter but still deliberate |
What ships with it
4 files 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.

html-deck is a skill published in the GitHub repository atman-33/workhub (2 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 1,751 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
