Summary

Defines an open protocol for agent work contracts, verifiable execution, and acceptance between AI agents. Uses cryptographic signatures (ed25519) and evidence-carrying messages so agents can authorize tasks, emit verifiable proofs of work, and record acceptance or rejection. The spec and Python reference include message formats for authorization, proof-carrying-work, and audit-friendly receipts. See the Open Agent Specification (Agent Spec).

Key Benefits

As agents autonomously delegate and transact, knowing what work was requested and whether it was completed becomes crucial for trust. OpenWorkProof provides a machine-readable contract and verifiable evidence so agents (and humans) can audit outcomes and build reputations based on concrete proofs. This shifts evaluation from ad-hoc logs to structured, cryptographically-signed artifacts useful for agent-to-agent evaluation and long-term track records. For broader interoperability, consider the Agent-to-Agent Protocol (A2A), and for patterns that support verification, look to the Mutual Verification Pattern.

Ideal For

Best for teams building multi-agent systems that need verifiable task authorization, evidence for acceptance, and audit-ready proofs of execution. In complex architectures, applying the Hierarchical Multi-Agent Pattern can help organize governance and trust across levels.

Real-World Examples

  • Require cryptographically-signed task authorizations and results for agent exchanges
  • Record verifiable evidence of task execution for agent reputation and audits
  • Enforce acceptance/rejection workflows with machine-readable receipts for dispute resolution
