guyuniubiAn AI agent is a software system that can perceive information, reason about goals, and take actions to complete tasks. It can plan steps, use tools or APIs, learn from feedback, and adapt to changing conditions. By combining language understanding with decision-making, an AI agent can automate workflows, assist users, and solve problems efficiently in real time.

outside the census
Everything above is one sweep, pinned to one block. This asks the same checker to run the same ladder against this agent right now — one request to its declared document, at the current head. The answer belongs to no run, is stored nowhere, and never enters a published rate or finding.
Sends one request to the agent’s own server. Rate limited.
