App-level security audit and hardening for Capacitor apps. Use when the user wants a security review, OWASP MASVS check, or pentest fixes; runs the Capgo scanner (`npx @capgo/capgo-sec scan`, `capsec`, rule IDs like SEC001, NET003, CAP004); finds API keys or `.env` values in the web bundle; stores tokens in `@capacitor/preferences` or `localStorage`; needs Keychain/Keystore storage, certificate pinning, CSP, or root/jailbreak detection; or sees `server.cleartext`, `allowNavigation`…

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.

What the file says

# Capacitor Security

Audit and harden the app layer of a Capacitor app: secrets in the bundle, on-device storage, network transport, WebView and native bridge exposure, and platform manifests.

## When to Use

TRIGGER when:
- The user asks for a security audit, OWASP Mobile Top 10 / MASVS review, or wants to fix pentest findings.
- The user wants to run or interpret `@capgo/capgo-sec` (`capsec`) results, rule IDs such as `SEC001`, `STO002`, `NET003`, `CAP004`, `AND004`, `IOS001`.
- API keys, service-role keys, or `.env` values appear in `src/`, `dist/`, `www/`, or `capacitor.config.*`.
- Auth tokens are stored with `Preferences.set`, `localStorage`, IndexedDB, or plain SQLite.
- `capacitor.config.*` contains `server.cleartext: true`, `server.url`, broad `server.allowNavigation`, `android.allowMixedContent`, or `webContentsDebuggingEnabled: true`.
- Native files contain `NSAllowsArbitraryLoads`, `android:usesCleartextTraffic="true"`, `android:allowBackup="true"`, `android:debuggable`, or exported components without permissions.
- The user needs certificate pinning, a Content Security Policy, screenshot protection, or root/jailbreak detection.

How to install

The exact contents, by fingerprint

mdr add cap-go/capgo-skills/capacitor-security@sha256:8de1237ec8e33d5a

The line at the top of this page pins the label git:20261011.86834d4, 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.
