Thread Based Inter Agent Communication With Message Routing

via “multi-agent team coordination with messagebus”

Bash is all you need - A nano claude code–like 「agent harness」, built from 0 to 1

Unique: Uses message passing as the primary coordination mechanism instead of shared state or RPC, making agent interactions explicit and auditable. Each agent remains independent and can be reasoned about in isolation.

vs others: Decouples agents more cleanly than shared-state approaches because agents don't need to know about each other's internal state. Easier to test and debug because message flows are visible.
