What is slidev-themes?

A guide to using and customizing Slidev themes, which control the visual style, layouts, colors, and components of a presentation. It covers built-in, package-based, local, and custom themes.

Use it to select a Slidev theme, configure theme options, install a missing theme, eject one for editing, or create a theme of your own.

It explains how to choose a consistent presentation design and change it when the defaults do not fit. It also shows how to install or modify themes.

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	$0.00028	$0.02279
Opus 5	$0.00014	$0.01140
Sonnet 5	$0.00006	$0.00456
Haiku 4.5	$0.00003	$0.00228

Security

Grade A, and why

slidev-themes 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 11d 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.
