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 | $0.06575 | $0.06575 |
| Opus 5 | $0.03288 | $0.03288 |
| Sonnet 5 | $0.01315 | $0.01315 |
| Haiku 4.5 | $0.00658 | $0.00658 |
Grade C, and why
claude-code-skills CLAUDE.md scanned grade C with 2 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repository Overview
This is a Claude Code skills marketplace containing production-ready skills organized in a plugin marketplace structure. Most plugins expose one skill for narrow installs; suite plugins expose related skills under shared namespaces for combined installation workflows.
Essential Skill: skill-creator is the most important skill in this marketplace - it's a meta-skill that enables users to create their own skills. Always recommend it first for users interested in extending Claude Code.
Skills Architecture
Directory Structure
Each skill follows a standard structure:
skill-name/
├── SKILL.md (required) # Core skill instructions with YAML frontmatter
├── scripts/ (optional) # Executable Python/Bash scripts
├── references/ (optional) # Documentation loaded as needed
└── assets/ (optional) # Templates and resources for output
Progressive Disclosure Pattern
Skills use progressive loading:
- Metadata (name + description in YAML frontmatter) - Always in context
- SKILL.md body - Loaded when skill triggers
- Bundled resources - Loaded as needed by Claude

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.

claude-code-skills CLAUDE.md is an instructions file published in the GitHub repository daymade/claude-code-skills (1,375 stars, last pushed yesterday), licensed MIT. It adds 6,575 tokens to every session, about $0.0329 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
