[COMMAND_EXECUTION]: The skill employs standard grep commands to identify existing BillingClient references and Gradle dependency declarations within the local project source. These discovery steps are restricted to reading project structure and do not involve executing untrusted code or modifying system settings.
[EXTERNAL_DOWNLOADS]: The instructions recommend adding the official Google Play Billing Library dependency and reference documentation from the author's own domain (revenuecat.com). These resources are well-known, reputable, and consistent with the skill's stated purpose of aiding Android billing integration.
