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.

Security

Grade A, and why

code 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.

What it actually says

Slidev Code Blocks

Code presentation features including highlighting, editor integration, and animated transitions.

For code block syntax, highlighting options, and editor configuration, see references/code.md.

Anti-fabrication

This skill follows core:anti-fabrication. Verified claim-by-claim against live slidevjs/slidev source (claude-skills-223, 2026-08-05) — line-highlighting and Magic Move against docs/features/line-highlighting.md and docs/features/shiki-magic-move.md (added the undocumented {hide}/{none} line values and Magic Move's {at:}/duration/ title-bar options); code groups against docs/features/code-groups.md (corrected: groups require comark: true, not mdc: truemdc is a deprecated-but-working alias); Monaco editor against docs/features/monaco-editor.md and packages/types/src/ frontmatter.ts (all confirmed, no changes); import-snippet against docs/features/ import-snippet.md (confirmed exact match including the "since v0.47.0" version claim). The finally code-block option was independently re-verified against source (CodeBlockWrapper.vue's prop declaration) after two earlier revisions of this pass wrongly called it nonexistent from a docs-only search. Re-verify against a fresh slidevjs/slidev clone before asserting a code-block feature this skill doesn't cover.

Files

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.

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.
