Headless Preview Testing & Responsive Visual Inspection Engine
Autonomous pre-delivery browser test execution with multi-viewport visual snapshots and self-healing runtime error recovery.
Eliminating Broken AI Generations
A persistent issue with AI code generators is the "looks good in text, breaks when clicked" syndrome. Subtle JavaScript bugs, missing event listeners, or unhandled null references frequently ruin the user experience.
Autonomous Action Chains & Viewport Audits
In v1.3.5, the harness executes native headless browser testing using preview_test before ending the turn. The engine simulates user interaction: clicking tabs, opening modals, submitting forms, and inspecting the DOM across desktop (1280x800), tablet (768x1024), and mobile (390x844) viewports. If a console error is detected, the agent automatically intercepts the stack trace and repairs the code before delivery.
