Check your Firebase rules before you launch
For anyone launching a Firebase app: check that strangers and other users cannot read or change your Firestore, Storage, or Realtime Database data. Reads your rules files and flags test-mode rules that expire, rules open to anyone, rules that only check "signed in", catch-all wildcards that override everything, profiles where users can edit their own role or plan, and uploads with no size limit, then drafts safer rules for you to test in the emulator. Never connects to Firebase.

How this works
- It is a skill: written instructions Claude reads when your request matches what the skill is for. You do not call it by name; just ask for the task.
- While it works, it reads and changes files in the places it lists, nowhere else.
- It runs these commands on your computer: node scripts/firebase-rules-audit.mjs.
- Nothing runs until you choose to use it, and you can remove it any time.
What it can access
What this kit declares, in the same words the CLI shows before you install. On Claude Code the CLI turns these into permission rules, so the agent stops anything undeclared.
Command
Runs the command: node scripts/firebase-rules-audit.mjs (with any arguments, without asking)
