What the skill teaches

A Firebase skill from the rsc-harness collection that steers an agent away from two common mistakes: treating Firestore like a SQL database and leaving data open to the internet. It covers modelling documents around read patterns, writing security rules as the real access control, Auth and custom claims, second-generation Cloud Functions, Cloud Storage, and the modular web and Admin SDKs, followed by a list of anti-patterns and a verification step. It points to sibling skills for Supabase, SQL databases and general Google Cloud work, and includes reference files, test cases and a verify script.
