- Firebase Security Rules for data access
- Explanation of core authentication concepts (Users, Providers, Tokens)
Use Cases
- Implementing user sign-in and sign-up flows
- Managing user accounts and profiles
- Securing data access with Firebase Authentication rules
- Integrating federated identity providers like Google, Facebook, etc.
Non-Goals
- General Firebase project setup or management
- Configuration of other Firebase services (e.g., Firestore, Storage)
- Detailed error handling for every possible SDK exception
Documentation
- info:Configuration & parameter referenceThe SKILL.md mentions prerequisites like Firebase Project creation and CLI installation, but detailed parameter references for `firebase.json` configuration or CLI commands are not explicitly documented.
Compliance
- info:GDPRThe skill deals with user authentication and may involve personal data (email, display name) passed to Firebase services. It doesn't contain explicit sanitization steps but relies on Firebase's handling of this data.
Execution
- info:Pinned dependenciesThe skill guides users to install Firebase CLI and SDKs, often recommending the latest versions, but does not explicitly pin specific dependency versions within its own bundle.
Practical Utility
- info:Edge casesWhile the skill covers core concepts and setup, explicit documentation of failure modes, symptoms, and recovery steps for edge cases (e.g., rate limits, expired credentials) is not detailed.
