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 AGENTS.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 5d 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.

How to add new skills and rules

This guide explains how to structure and add new skills to this repository.

Skill structure

Each skill should follow this structure:

skills/
└── knock-your-skill-name/
    ├── SKILL.md          # Human-readable guide (required)
    └── rules/            # Rule files directory (required)
        ├── rule-1.md
        ├── rule-2.md
        └── ...

Step-by-step guide

1. Create the skill directory

Create a new directory under skills/ with a descriptive name using the knock- prefix and kebab-case:

mkdir -p skills/knock-your-skill-name/rules

2. Create rule files

Add individual rule files in the rules/ directory. Each rule file should:

  • Use markdown format (.md)
  • Include frontmatter with metadata:
    ---
    title: Your rule title
    description: Brief description of the rule
    tags:
      - relevant-tag-1
      - relevant-tag-2
    category: knock-your-skill-name
    last_updated: YYYY-MM-DD
    ---
    
  • Use sentence case for all titles and headings
  • Be focused on a single topic or theme
  • Include examples and practical guidance

Example rule file structure:

---
title: Rule name in sentence case
description: What this rule covers
tags:
  - tag1
  - tag2
category: knock-your-skill-name
last_updated: 2026-01-23
---

# Rule name in sentence case

## Section heading

Content here...

### Subsection

More content...

3. Create SKILL.md

Create a SKILL.md file that serves as a human-readable guide. It should:

  • Provide an overview of the skill
  • Explain how to use the different rules
  • Reference rule files using relative paths (e.g., rules/rule-1.md)
  • Include quick reference sections
  • Use sentence case for all headings

Example SKILL.md structure:

---
name: knock-your-skill-name
description: Brief description of what this skill provides.
---

# Your skill name

Brief description of what this skill provides.

## Overview

List the rule files and what they cover.

## How to use this skill

### For specific use case 1

1. **Start with rule X** (`rules/rule-x.md`)
   - What to look for
   - Key principles

2. **Check rule Y** (`rules/rule-y.md`)
   - Additional considerations

## Rule files reference

- `rules/rule-1.md` - Description
- `rules/rule-2.md` - Description

## Quick reference

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.
