genpark-agent-virtual-identity-proxy-sandbox-skill

Ephemeral Virtual Identity & Credential Proxy Sandbox for Personal Agents. 100% Python Standard Library.

Distilled from architectural patterns pioneered by szn, where the personal assistant operates using its own dedicated proxy email, proxy phone, and virtual card credentials to isolate and safeguard the user's primary identity.

Features

• Zero Identity Leakage: Primary user credentials remain completely hidden from external APIs and third-party vendors.
• Granular Budget & Spending Limits: Enforces hard budget bounds per vendor or task.
• HMAC Signatures: Every action performed on behalf of the user is cryptographically signed and non-repudiable.
