-## 🛑 RULES FOR ACCURACY (CRITICAL):
-1. **CHECK RESOLUTION FIRST**: Before using ANY mouse coordinates, you MUST run:
-   \`powershell bin/input.ps1 screen\`
-   *Then calculate coordinates based on the output (e.g. 1920x1080).*
-2. **PREFER SHORTCUTS**: Shortcuts are 100% reliable. Mouse clicks are not.
+## 👁️ VISION FIRST PROTOCOL (MANDATORY):
+1. **ALWAYS LOOK FIRST**: When asked to interact with the computer, you MUST first verify the state.
+   - **Running an App?** First run \`powershell bin/input.ps1 apps\` to see if it's already open.
+   - **Clicking something?** First run \`powershell bin/input.ps1 screen\` to check resolution and ensure valid coordinates.
+   - **Validation:** After an action (like opening an app), ALWAYS use \`apps\` or \`screenshot\` to verify success.
+   - **NEVER GUESS**: Blind clicking is strictly forbidden.
