AFK: Instructions file for Claude Code

CLAUDE.md

AFK CLAUDE.md is an instructions file for Claude Code from LilMGenius/AFK. It costs 523 tokens per session, scanned A, original, MIT.

Project instructions for AFK, a tool that lets a command-line AI agent view web-game screens and control games through Chrome. CDP is Chrome's browser-control interface.

In plain words
What is it for?
Use them to coach or autonomously play supported games such as 2048 and Minesweeper, using browser page data, keyboard input, or CDP controls.
Why use it?
They explain how the agent should read game state and send controls while keeping decision-making in the command-line agent.

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

AFK 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 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.

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.

What it actually says

AFK — Claude Code Project

Eyes & Hands for AI Agents. You go AFK. AI opens its eyes, grabs your mouse.

What This Project Is

AFK gives Claude Code (and any CLI agent) the ability to see web game screens and control them autonomously.

  • Eye (skills/eye/SKILL.md): How to read game state via DOM/CDP
  • Hand (skills/hand/SKILL.md): How to control games via CDP/keyboard
  • Brain: That's YOU, Claude. The CLI is the brain. Don't build another one.

How to Use

Load the main skill and start playing:

# Coach mode (advise only)
Read SKILL.md, then: afk:coach 2048

# Play mode (autonomous)
Read SKILL.md, then: afk:play 2048

Project Structure

└── server.js             ← WebSocket server (CLI ↔ Extension)

Core Principles

  1. Brain = CLI: Claude IS the brain. No separate AI module.
  2. Code = Minimal: Chrome Extension ~100 lines. Everything else is Markdown.
  3. GAME.md = Plugin: Each game file is a plugin. Community can contribute.
  4. DOM First: Read DOM before taking screenshots. Faster, cheaper, more accurate.

Starting a Session

  1. Read SKILL.md for the full AFK skill
  2. Read skills/eye/SKILL.md and skills/hand/SKILL.md
  3. Check games/ for the target game's strategy file
  4. Start the strategy loop

WebSocket Server (Optional)

For Chrome Extension overlay:

node server.js
# Starts WebSocket on ws://localhost:38377
# Load chrome-extension/ in Chrome for visual overlay
Changes

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.
