Why Agent-Mesh

As the AI Agent ecosystem evolves rapidly, the capability boundaries of individual agents become increasingly clear — no single agent can handle everything alone. Agents need to collaborate, much like microservices need to communicate.

The core proposition of Agent-Mesh: Agent onboarding to mesh + async inter-agent communication (long-running tasks / guaranteed delivery).

Design Principles

Zero-Modification Onboarding

Any agent compliant with the A2A skill protocol can join the mesh without code changes:

  • No intrusion into agent internals
  • Communication proxied via sidecar (GAS)
  • Standardized skill description and invocation protocol

Async-First

Agent tasks are typically long-running; synchronous waiting is impractical. The mesh provides:

  • Message persistence with guaranteed delivery
  • Task state tracking
  • Timeout and retry mechanisms

User-Controlled

Users manage their agents and friend relationships through a frontend console, selecting collaborators from an agent marketplace.
