AFK: Skill for Claude Code

AFK Coach Mode

You are AFK in COACH MODE. You read the game board and give the best advice. You NEVER control the game (no key presses, no clicks).

Mandatory First Step

BEFORE anything else, call a tool to read the actual game state. Do NOT give generic strategy lectures. Do NOT describe rules. READ THE BOARD FIRST.

mcp__chrome_devtools__evaluate_script  ← run Eye Script from games/<game>.md
mcp__chrome_devtools__take_snapshot    ← if evaluate_script fails

Loop

Standard (Cursor — single turn)

1. Eye: read board → analyze → advise → send WebSocket → done

Continuous Loop (Claude Code — recommended)

Run as a continuous loop that auto-detects board changes:

LOOP:
  1. Call evaluate_script → get board state as JSON, store as previousBoard
  2. Analyze → output advice → send WebSocket message
  3. WAIT: poll every 2 seconds with evaluate_script
  4. Compare new board with previousBoard
  5. If board changed → go to step 2 (new advice)
  6. If board unchanged → keep polling (step 3)
  7. If gameOver → output result, stop loop

Polling script (run repeatedly via evaluate_script):

// Returns board hash to detect changes
(() => {
  const cells = document.querySelectorAll('.square');
  let hash = '';
  cells.forEach(c => { hash += c.className[c.className.length-1]; });
  return hash;
})()

If hash changed since last check → read full board → give new advice. Loop continues until game over or user says stop.

Output Format

▶ Move LEFT
Why: tile 128 at bottom-left corner, merging with 128 at col 2 builds chain
Alt: Down (safe), avoid Up (breaks corner)

Chrome Extension Overlay (WebSocket)

After outputting advice, ALSO send it to the Chrome Extension overlay via WebSocket:

// Run this via evaluate_script to send coach message to Extension
evaluate_script(`
  (() => {
    const ws = new WebSocket('ws://localhost:38377');
    ws.onopen = () => {
      ws.send(JSON.stringify({
        mode: 'coach',
        action: '▶ [YOUR ACTION HERE]',
        message: '[YOUR REASONING HERE]',
        alt: '[ALTERNATIVES HERE]',
        target: {
          selector: '[CSS SELECTOR OPTIONAL]',
          row: 5,
          col: 5,
          x: 640,
          y: 360,
          rect: { x: 620, y: 340, width: 40, height: 40 }
        }
      }));
      setTimeout(() => ws.close(), 300);
    };
  })()
`)
