Watch out for

• It can delete Firestore documents and Crashlytics notes

  The delete tools act on whichever project is active. Check the active project before you ask for deletions.

• It can send push notifications to real devices

  The messaging tool sends to any device token or topic you name. Use a test topic while you build.

• It acts with your full Firebase CLI login

  There is no read-only setting. Sign in with an account that has only the roles you want the assistant to use.

• Some tools ask Gemini and can be wrong

  The README warns that Gemini in Firebase can give plausible but incorrect output. Check generated schemas and code before you deploy.
