Summoner – Protocol enabling AI agents to negotiate across companies

Summary: Summoner is a protocol that allows AI agents to discover, negotiate, and coordinate decisions across organizations with auditable decision traces. In a logistics simulation, it enabled two agents to negotiate 592 shipping decisions, reducing costs by 17.6% while providing real-time tradeoff analysis.

What it does

Summoner lets AI agents discover each other, negotiate structured proposals, sign and verify outcomes, and generate auditable decision traces across companies.

Who it's for

It is designed for developers building multi-agent systems requiring cross-organization coordination.

Why it matters

It solves the problem of AI agents failing to coordinate effectively beyond single-company boundaries.
