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.

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 | $0.00306 | $0.00306 |
| Opus 5 | $0.00153 | $0.00153 |
| Sonnet 5 | $0.00061 | $0.00061 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
skillkit CLAUDE.md 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
Skillkit
A collection of AI coding skills. Each skill lives in skills/<skill-name>/SKILL.md.
GitHub Pages
The landing page at docs/index.html is published to https://sacredvoid.github.io/skillkit.
When adding a new skill, always update docs/index.html:
- Add a new CSS card class (
.card-<name>) with grid span, gradient, hover shadow, icon, title, and tag color styles - Add the card HTML to the bento grid (before the full-width Local Image Gen card at the bottom)
- Update the skill count in the section title ("Nine skills. One install." etc.)
- Update the
<meta>description tags in<head>to mention the new skill - Update the responsive media query to include the new card class
- Pick a unique color from the existing CSS variables or add a new one to
:root
Also update README.md to add the new skill to the skills table and add a details section.
Skill File Format
Each skill has YAML frontmatter:
---
name: skill-name
description: "What the skill does"
argument-hint: "[usage example]"
disable-model-invocation: true
allowed-tools: [tool list]
---
Git Remote
Uses [email protected]:sacredvoid/skillkit.git (personal-git SSH alias may also be used).
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.

skillkit CLAUDE.md is an instructions file published in the GitHub repository sacredvoid/skillkit (10 stars, last pushed 5mo ago), licensed MIT.
