Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00363 |
| Opus 5 | $0.00017 | $0.00181 |
| Sonnet 5 | $0.00007 | $0.00073 |
| Haiku 4.5 | $0.00003 | $0.00036 |
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: true — mdc 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.
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.
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.
- 2d ago First seen · 27 lines · 35 tokens per session scan A fc51d18380ec
code is a skill published in the GitHub repository vinnie357/claude-skills (24 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 363 once invoked, about $0.0002 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 2026-09-04.
