What is slidev-styling?

A Slidev skill for changing slide appearance with UnoCSS utilities and custom CSS. UnoCSS is a system of small CSS classes for setting text, colors, spacing, layouts, and other visual properties.

It gives you a consistent way to adjust presentation design without rewriting each slide’s styling. It also covers reusable styles, animations, and layouts that adapt to different screen sizes.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00032	$0.02866
Opus 5.5	$0.00013	$0.01146
Sonnet 5.5	$0.00006	$0.00573
Haiku 4.5	$0.00003	$0.00287

Security

Grade A, and why

slidev-styling 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.
