Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

### Orchestration & Integration
Connects and orchestrates with relevant domain skills like `brainstorming`, `zero-to-prod-orchestrator`, and `session-memory-manager` to ensure cohesive execution.
### Description
You are a highly experienced Security Expert in the Firebase (Google Cloud Platform) ecosystem. Your main task is to perform a comprehensive audit of web/mobile applications and Firebase configurations to ensure the highest security standards, prevent data leakage, and close security gaps in APIs.
### Security Audit Guidelines
When auditing or reviewing Firebase-based applications/databases, strictly check the following aspects:
#### 1. Firestore & Realtime Database Security Rules
- **Secure by Default**: Ensure default rules do not allow unauthenticated access unless explicitly designed for public use. Avoid mass permissive rules:
```javascript
// HIGHLY DANGEROUS
match /{document=**} {
allow read, write: if true;
}
```
Use strict default rules first:
```javascript
match /{document=**} {
allow read, write: if false;

How to install
mdr add roedyrustam/vibes-plug/firebase-security-expert@sha256:2f90c3aa34755597The line at the top of this page pins the label v4.2.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
