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.

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

skills 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 3d 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.

Creating a New Skill

1. Create Skill Directory

mkdir -p skill-name/references
touch skill-name/SKILL.md

2. SKILL.md Frontmatter

---
name: skill-name
description: This skill should be used when the user asks to "specific phrase 1", "specific phrase 2", or "specific phrase 3". Be concrete about trigger conditions.
license: MIT
metadata:
  author: Schwepps
  version: "1.0.0"
  category: marketing|music|development|etc
  tags: tag1, tag2, tag3
---

Critical: The description field determines when Claude activates the skill:

  • Use third-person phrasing: "This skill should be used when..."
  • Include exact phrases users would say to trigger it
  • Be specific and concrete, not vague

3. SKILL.md Content Structure

After frontmatter, include:

  • When to Use: Clear activation criteria
  • Workflow/Methodology: Phased approach with specific steps
  • Output Format: Template showing expected deliverable structure
  • Scoring Guide (for audits): Quantitative evaluation criteria
  • Quick Version: Abbreviated workflow for rapid execution

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.
