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

claude-plugins CLAUDE.md scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Skill Anatomy

Each skill has:

  • SKILL.md: Main file with YAML frontmatter (name, description, version) and markdown body containing workflows, examples, and troubleshooting
  • references/: Deep-dive documentation loaded when Claude needs more detail
  • examples/: Working code that Claude can adapt

Key Conventions

SKILL.md Frontmatter

---
name: skill-name
description: This skill should be used when the user asks to "specific phrase 1", "specific phrase 2", or mentions specific-topic.
version: 1.0.0
---

The description field should contain specific trigger phrases users would say, not vague descriptions.

Content Guidelines

  • Verify APIs/endpoints before documenting - never guess
  • Include working curl commands and code snippets
  • Document common errors and edge cases
  • Keep SKILL.md concise; put detailed docs in references/

Working on This Repo

When adding a new skill:

  1. Create folder: skills/<skill-name>/
  2. Add SKILL.md with proper frontmatter
  3. Add references/ and examples/ as needed
  4. Update skills/README.md with the new skill
  5. Update CHANGELOG.md

When modifying existing skills:

  • Bump version in frontmatter according to semver
  • Update CHANGELOG.md

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.
