Agent identity provider — own email address and E2E-encrypted credential vault. Use when storing or retrieving passwords for services, logging into services with stored credentials, checking email inbox, receiving OTP/verification codes via email, signing up for services, getting your agent's email address, or any task where the agent needs its own identity separate from the user's. Replaces 1Password + AgentMail with a single skill — no desktop app, no tmux, fully autonomous.
