Default output: return only the result, blockers, and required evidence. Omit preambles, process narration, repeated context, confidence scores, and follow-up offers. Use at most five bullets unless a required artifact or schema needs more.

Control UI

Use local browser automation to verify UI behavior with evidence. First reuse the repo's own Playwright, browser, or Electron harness if it exists; otherwise assemble a temporary local harness around the app's dev server or Chromium debug port.

What It Is Used For

• Reproducing UI bugs that depend on real browser focus, keyboard input, scrolling, resizing, or rendering.
• Verifying visual or accessibility changes with screenshots and snapshots.
• Checking local web, IDE, or Electron behavior before shipping.
• Capturing console logs, network logs, CPU profiles, traces, or heap snapshots.
• Creating before/after evidence for a verification step (e.g. verification-loop).
