Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md.

This is sacredvoid/skillkit's own configuration. It tells Claude Code how to work on skillkit itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything skillkit configures →

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

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 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.

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:

  1. Add a new CSS card class (.card-<name>) with grid span, gradient, hover shadow, icon, title, and tag color styles
  2. Add the card HTML to the bento grid (before the full-width Local Image Gen card at the bottom)
  3. Update the skill count in the section title ("Nine skills. One install." etc.)
  4. Update the <meta> description tags in <head> to mention the new skill
  5. Update the responsive media query to include the new card class
  6. 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).

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.
