How does this skill help with Firestore permission errors?

It provides a structured workflow to use the Rules Playground, allowing you to simulate requests and view evaluation traces to identify the specific lines where security rules are failing.

What happens to my emulator data when I restart?

The skill teaches you how to use the export command before shutdown and how to start the emulators with the --import flag to maintain data persistence across sessions.

Can it fix Firebase emulator port conflicts?

Yes, it includes commands to identify which processes are using required ports like 4000, 5001, or 8080 and provides the necessary bash commands to clear them.

Does this skill work with production deployment errors?

Absolutely. It includes steps to analyze the firebase-debug.log, verify project targets in .firebaserc, and validate predeploy hooks locally before attempting another deploy.
