A guide to Slidev's Markdown-based slide syntax and structure. It explains slide breaks, frontmatter settings, layouts, speaker notes, click animations, and transitions.

Use it to organize Slidev slides, configure layouts and metadata, add presenter notes, and create animations or transitions.

It helps you express presentation structure and behavior correctly without having to learn the framework's syntax by trial and error.

Per session 35 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Origin original No closer match found in the catalogue.

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	$0.00035	$0.00081
Opus 5.5	$0.00014	$0.00032
Sonnet 5.5	$0.00007	$0.00016
Haiku 4.5	$0.00003	$0.00008

Security

Grade A, and why

syntax 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.

Changes

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.
