GTM Tracking Plan

Give it a site URL and get back a complete Google Tag Manager build spec — every tag, trigger, and variable to create, plus the exact dataLayer.push() snippets a developer drops into the site. It's the implementation half of a measurement plan. No account connection required.

Best run after /ga4-measurement-plan — pass the same URL and this skill builds the GTM container to deliver that plan. Run alone, it derives a sensible plan first.
