name: security-audit description: Scans code for security vulnerabilities, hardcoded secrets, and unsafe patterns in React Native and Expo applications. Use before merging sensitive changes or as part of a regular audit.

Security Audit Skill

This skill focuses on making the application robust against common mobile security threats.

Instructions

1. Secret Scanning: Check for API keys, passwords, or tokens in the codebase.
2. Data Storage: Ensure sensitive data is stored in expo-secure-store and not AsyncStorage.
3. Network: Verify that all API calls use HTTPS and that SSL pinning is considered for high-security apps.
4. Input Validation: Check for unsanitized inputs that could lead to XSS or injection.
5. Permissions: Review app.json for unnecessary permissions.

Tools to Simulate/Use

• bunx audit (for dependencies)
• Custom grep patterns for secrets (e.g., sk-, AIza, ghp_)
• Checking for dangerouslySetInnerHTML in web-related components.
