What it does

This skill gives an AI agent a checklist-style guide for Google Consent Mode v2, a Google system that adjusts how analytics and advertising tags behave depending on whether a visitor agreed to cookies, which is relevant to privacy rules such as GDPR. When installed, the agent is told to check that consent states are sent correctly, to point to the ad_user_data and ad_personalization consent types when updating Google Tag Manager or gtag.js, and to look for performance problems like slow loads or heavy assets, confirming any bottleneck with DevTools, Lighthouse, or field data before recommending changes.

Great for

  • Web developers who need to verify their Google Consent Mode v2 tags are working
  • Marketers or site owners preparing for privacy compliance in advertising regions
  • Teams investigating whether consent tags slow down page loads

Skip it if

  • Legal compliance decisions: the skill is a technical guide and does not replace advice from a lawyer on GDPR or other regulations, and its wording is general
  • Sites with no Google tags or no consent banner, where the skill's guidance does not apply

Try asking

  • “Check whether my site's Google Consent Mode v2 setup sends the correct consent states”
  • “Audit my page load and tell me if the consent tags are causing slow rendering, with measurements”
  • “Update my GTM setup to add the ad_user_data and ad_personalization consent types”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent access to your site's HTML or GTM export so it can check the real configuration rather than guessing.
  • Ask for measurements (DevTools, Lighthouse or field data) to be included, since the skill asks the agent to confirm bottlenecks before recommending changes.
  • Treat the output as a technical starting point and verify consent behaviour with your legal or compliance team.
