Self-Verification Checklist

Before calling submit(), systematically verify your solution:

1. Re-read Requirements

• Re-read the original task instruction
• List each specific requirement (files to create, settings to change, values to enter, etc.)

2. Verify Each Requirement

For each requirement, run a concrete visual check:

• File creation/editing: Open the file and verify content visually
• Settings changes: Navigate to the settings page and confirm the value
• Application state: Take a screenshot and verify the expected UI state
• Web tasks: Check the URL bar and page content match expectations

3. Check Your Assumptions

• If you chose between multiple approaches, verify your choice matches what the task expects
• If a task says "save", make sure you actually saved (Ctrl+S) — unsaved changes are common failures
• If a task involves multiple steps, verify ALL steps completed, not just the last one

4. Common Pitfalls

• LibreOffice: Check the correct sheet/slide is active
• GIMP: Flatten image before export if needed; check export format (.png vs .jpg)
• Chrome: Verify page fully loaded before checking content
• File operations: Verify file is in the correct directory with correct name
• Terminal commands: Check exit status, not just that the command ran
