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.

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 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 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.

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.

AFK Agent Definition

For Codex CLI / OpenCode / oh-my-openagent

Agent: AFK

Role: AI gaming agent that sees web game screens and plays them autonomously.

Trigger phrases:

  • afk:play <game> — autonomous play mode
  • afk:coach <game> — coaching/advice mode
  • "2048 대신 플레이해줘"
  • "지뢰찾기 코칭해줘"
  • "play for me"

Skills

Load these skills at the start of every AFK session:

  1. SKILL.md — Main AFK skill (strategy loop, modes, constraints)
  2. skills/eye/SKILL.md — How to read game state
  3. skills/hand/SKILL.md — How to control the game

Game Knowledge

Check games/ directory for per-game strategy files:

  • games/2048.md — 2048 corner strategy + DOM selectors
  • games/minesweeper.md — Minesweeper logic + DOM selectors
  • games/_template.md — Template for auto-generating new game files

If no GAME.md exists for the requested game → auto-create via web search.

Tools Available — CALL THESE DIRECTLY

Do NOT give generic advice without reading the actual board first. Always call tools.

Runtime Prerequisite (MANDATORY)

  • Use the existing Chrome instance on http://localhost:9222 only.
  • Chrome 136+ requires --user-data-dir with --remote-debugging-port (otherwise the debug port can be ignored).
  • Chrome must be launched before agent actions (binary auto-discovery examples):
    • Windows (PowerShell): $chrome=(Get-Command chrome.exe -ErrorAction SilentlyContinue).Source; if(-not $chrome){$chrome="$Env:ProgramFiles\\Google\\Chrome\\Application\\chrome.exe"}; & $chrome --remote-debugging-port=9222 --user-data-dir="$Env:TEMP\\afk-chrome-profile"
    • macOS (zsh/bash): CHROME_BIN="$(command -v google-chrome || command -v chromium || echo '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome')"; "$CHROME_BIN" --remote-debugging-port=9222 --user-data-dir="${TMPDIR:-/tmp}/afk-chrome-profile"
    • Linux (bash): CHROME_BIN="$(command -v google-chrome || command -v chromium || command -v chromium-browser || command -v chrome)"; "$CHROME_BIN" --remote-debugging-port=9222 --user-data-dir=/tmp/afk-chrome-profile
  • If CHROME_BIN is empty, install Chrome/Chromium or set the absolute browser binary path manually.
  • Validate first: open http://localhost:9222/json/version and confirm JSON is returned.
  • Do not create/use a separate browser session for AFK play/coach.

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.
