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 | $0.08575 | $0.08575 |
| Opus 5 | $0.04287 | $0.04287 |
| Sonnet 5 | $0.01715 | $0.01715 |
| Haiku 4.5 | $0.00857 | $0.00857 |
Grade C, and why
cc-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 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
Eval results go in `EVALUATIONS.md` at the repo root. Append new skill sections — never overwrite previous runs. The file is wrapped in `<!-- prettier-ignore-start/end -->` so Prettier doesn't break the HTML spans. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
This is a Claude Code plugin containing AI agent skills covering engineering, marketing, and productivity domains. The repository provides reusable skill definitions that Claude Code can invoke across projects.
Project Structure

Agent Skills Specification
All skills MUST conform to the Agent Skills specification. Key requirements are summarized below; the spec is the source of truth when in doubt.
Frontmatter
New skills go in skills/<skill-name>/SKILL.md. Each SKILL.md has YAML frontmatter. Fields per the Agent Skills spec — this project requires all fields marked "Project-required":
| Field | Required | Constraints |
|---|---|---|
name |
Spec-required | 1-64 chars. Lowercase a-z, digits, hyphens. No leading/trailing/consecutive hyphens. Must match parent directory name. |
description |
Spec-required | 1-1024 chars. Describes what the skill does and when to use it — this is the primary triggering mechanism. Be specific and slightly "pushy" to avoid under-triggering. |
license |
Project-required | License name or reference to a bundled license file. Use MIT for this project. |
compatibility |
Project-required | 1-500 chars. Describe actual requirements. Base: Designed for Claude Code or similar AI coding agents. Extend when needed: add Requires git, Requires internet access, Requires Python 3.14+ and uv, etc. Skills with no special requirements use the base string only. |
metadata |
Project-required | Must include author (string), version (semver a.b.c string, e.g. "1.0.0"), and openclaw (ClawHub discoverability fields — see below). |
user-invocable |
Project-required | Boolean. true for skills invocable as slash commands (e.g. /skill-name), false (default) for contextual skills that auto-trigger. |
allowed-tools |
Project-required | Space-delimited list of pre-approved tools. See "Allowed tools" below. |
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.

cc-skills CLAUDE.md is an instructions file published in the GitHub repository hssh8917/cc-skills (2 stars, last pushed 4d ago), licensed MIT. It adds 8,575 tokens to every session, about $0.0429 per session on Opus 5. A static security scan graded it C with 2 findings (hidden instructions, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
