Interface Contracts

Interface contracts define the agreement between two agents at their boundary — what Agent A provides, what Agent B expects, and the format that bridges the gap. Every pair of agents that regularly exchange work needs an interface contract. At 20 agents, that is up to 190 potential interfaces, but in practice, most agents interact with 3-5 others regularly. Our system maintains 47 active interface contracts.

Each contract specifies: the data format for both directions, the quality expectations for each direction, the escalation path when the contract is violated, and the review cadence. HUNTER-to-CLOSER: lead qualification payload, minimum ICP score of 65, weekly contract review. QUILL-to-RENDER: content brief with section structure, completed within 4 hours of request, monthly contract review. SCOPE-to-BLITZ: intelligence digest, classified by significance level, bi-weekly contract review.

Contracts that go un-reviewed drift. The review cadence is non-negotiable — it is the mechanism that catches interface mismatches before they produce conflicts. 73.84% of boundary conflicts trace to interface contracts that were not reviewed on schedule.
