## What it does

The skill helps investigate duplicate purchases, incorrect conversion values, enhanced conversion setup, and Consent Mode v2. It draws on reference guidance, diagnostic flowcharts, and BigQuery validation SQL. When integrations are connected, it can also query GTM, GA4, and advertising accounts.

Checks include comparing conversions across platforms, inspecting tags, and reconciling reports with Shopify or WooCommerce orders. Live account checks require Cogny MCP and the relevant connected integrations. Without that connection, the reference material, flowcharts, and SQL remain available, but account data cannot be queried.
