# 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. ## Usage `/gtm-tracking-plan example.com` — full GTM build spec for the site ## Steps ### 1. Establish the events to implement If a GA4 measurement plan already exists in the conversation, use its event taxonomy. Otherwise, `WebFetch` the site, infer the site type and funnel, and derive the event list yourself (the same logic as `/ga4-measurement-plan`, in brief). For each event you need: name, when it fires, its parameters, whether it's a key event. ### 2. Variables List every variable to create, by type: - **Data Layer Variables** — one per parameter pushed to the data layer (`ecommerce`, `value`, `currency`, `transaction_id`, `lead_source`, …) - **Built-in variables to enable** — Click Element, Click URL, Click Text, Form ID, Page Path, Page URL, plus the relevant ones per trigger - **Constant** — the GA4 Measurement ID (`G-XXXXXXX`) - **Lookup / RegEx table** — only if routing or value mapping is genuinely needed - **Consent state variables** — if Consent Mode is in scope Present as a table: variable
