README

HarnessMesh

**HarnessMesh is an agent-to-agent collaboration fabric for AI coding harnesses.**

NOT an LLM proxy.
NOT another model router.
NOT a vendor-specific wrapper.

HarnessMesh is the **broker, control plane, and collaboration fabric** that enables diverse AI coding harnesses to communicate directly with each other in real-time through standard tools (MCP) without human copy/paste.
