Activation Contract

Run this skill first for every HTML, CSS, React or browser JavaScript change.

Hard Rules

  • Do not implement client-side behavior from memory when current platform guidance is available.
  • Search before writing code; retrieve the most relevant result before implementation.
  • Use Google Modern Web Guidance through npx; it is not an MCP.
  • Follow the documented fallback guidance for features that are not Baseline Widely Available.

Execution Steps

  1. Run npx -y modern-web-guidance@latest search "<action-oriented task>" --skill-version 2026_05_16-c5e78707.
  2. Retrieve the selected guidance: npx -y modern-web-guidance@latest retrieve "<guide-id>".
  3. Apply it to the React/Vite implementation and test the relevant responsive/accessibility/performance behavior.
  4. Cite the guide ID in the PR or Linear evidence when it materially changed the implementation.

Output Contract

Return searched guide IDs, the applied decision, browser/fallback impact and validation evidence.
