Agent Reading Test (agentreadingtest.com) AI

Agent Reading Test is a benchmark that scores how well AI coding agents can reliably read different kinds of documentation web pages, including cases where content is truncated, hidden by CSS, rendered only via JavaScript, or buried in tabs and navigation chrome. Each test page uses hidden “canary” tokens and tasks based on real documentation failure modes, then compares which tokens the agent reports after completing the work. The results are submitted for a max score of 20 and are intended to highlight silent failure modes in agent web-fetch pipelines across platforms.
