Design Review

Purpose

Evaluate visual implementation against Figma, screenshots, reference images, or written specifications.

Native Antigravity Boundary

Mandatory CloakBrowser Boundary

This boundary applies before every browser action:

1. Run exactly:

   $HOME/.local/bin/cloakbrowser-cdp-health
   

   If the command is missing or exits nonzero, stop immediately and report NOT_PROVEN.

2. Browser execution is permitted only through:

   • the exact $HOME/.local/bin/playwright-cli executable; run-code and --filename are forbidden;
   • the approved Chrome DevTools MCP transport, exactly /bin/sh -c 'exec "$HOME/.local/bin/chrome-devtools-mcp" --headless --isolated --no-usage-statistics --no-performance-crux'.

3. Never execute the Webwright Python runtime, stock/raw/in-app Browser, browser_agent, node_repl, computer-use, Playwright MCP, raw Playwright, bunx, npx, direct package invocations, alternate CDP endpoints, alternate browser executables, alternate browser configs, or any fallback. No fallback is allowed.

webwright-task is compatibility intent routed to browser:validate; it never authorizes Webwright runtime execution.

When To Use

Use for Figma-to-code review, responsive visual checks, typography, color/token, layout, and accessibility deviations.

Inputs

Expected source, target URL, viewport matrix, dynamic masks, and thresholds.

Procedure

Use Figma MCP for the expected source, managed Playwright CLI for actual screenshots and responsive evidence, and managed Chrome DevTools MCP for DOM/runtime diagnosis. Rerun health immediately before each browser action.

Evidence Required

Report expected source, exact artifact paths, masks, thresholds, pixel/layout, typography/token/accessibility deviations, confidence, and NOT_PROVEN gaps.

Forbidden Actions

Do not approve visual quality without artifacts or bypass the browser boundary.

Acceptance Checks

Run python3 scripts/validate_gemini_browser_routing.py --strict.

Failure Reporting

Report each mismatch with source, viewport, severity, evidence, and any NOT_PROVEN state.
