Game Mechanics Validator Skill

The Validation Loop

1. Read the Plan: Load .agent/plan.md to find the "Definition of Done".
2. Write a Failing Test: Create a Vitest or Playwright test that simulates the player's action.
3. Analyze Implementation: Check the game's useEffect and event handlers.
4. Verify Playability: Run the test. If it fails, you must fix the code, not the test.

Automated Gameplay Simulation

• Use scripts to simulate "Speed-Playing" (running 100 turns in 1 second) to check for race conditions or state desyncs.
• Confirm that the "Play Again" button resets the state to exactly the initial values.
