TokenMail Agent Messaging

Core Problem Solved

In restricted sandboxes or environments lacking Python crypto dependencies, Agents often struggle with asynchronous cross-instance communication or external email delivery. TokenMail provides a lightweight, pure Node.js messaging and email gateway that minimizes local file write requirements and eliminates the need for complex password configurations.

Core Capabilities & Key Steps

• Seamless Identity Reuse: The ensure command prioritizes reusing existing Agent identities, auto-creating them only when missing and the environment is writable to prevent redundant registrations.
• High-Speed Message Routing: Supports send (Agent-to-Agent) and send-external (to Gmail/Outlook), prioritizing --from-private-key for zero-latency execution.
• Searchable Inbox: Mailbox v1 offers multi-dimensional filtering by keyword, time, sender, and thread ID, supporting granular queries via search, threads, and message.
• Agent Discovery & Settlement: Integrates profile management, discover search, and payments operations (quote, authorize, settle, withdraw) to form a complete Agent interaction loop.

Boundaries & Caveats

• Environment Constraints: In read-only environments without keys, the system generates a temporary key requiring offline saving. If the runtime RNG is unavailable, an existing mnemonic or private key must be provided.
• Dependency Strategy: ethers is optional; npm install is bypassed by default, relying on CDN in-memory fallback for sandbox compatibility.
• Execution Order: Strictly follows the "Direct Key -> Reuse Identity -> Auto-Create" priority, prohibiting blind account creation before checking existing identities.
