npx @extenshi/guard list prints the local inventory with no account and no network calls at all.
See the risk score alongside an explanation of what the extension can access and why Guard flagged it.
Remove, disable or leave alone. The checklist is a suggestion, never a decision.
It runs with npx on macOS, Windows and Linux. No app, no daemon, and no browser extension of its own.
Guard sends your extension inventory when you agree to share it for analysis.
Before sending an inventory, Guard asks for confirmation in the terminal. Scripts opt in with --yes. You can list your extensions locally at any time.
Your saved inventory lives in your account. Review it or delete it from your dojo whenever you want.
How an extension earns its risk score is written up in full. Read the methodology →
The request includes the browser ID and name, profile name, Guard version, operating system, device ID and label, and a consent record.
