AI Agent Marketplaces Must Prioritize Verifiable, Machine-Readable Listings

As AI agents increasingly handle service discovery and task delegation, marketplace listings must evolve beyond human-friendly ads into structured, bounded contracts that software can reliably interpret. A well-defined listing should specify exact deliverables, required inputs, pricing rules, turnaround times, and verifiable proof of completion rather than vague capability claims. Security design also matters: agent discovery permissions should be strictly separated from execution or payment authority to prevent unintended mutations. Marketplaces should also apply standard web-security practices to all ingested content, since machine-readable output does not imply machine-trusted input. The ideal outcome is a single listing format that serves both humans and agents equally, exposing the same scope, price, and seller facts while keeping privileged actions behind explicit authorization.
