A benchmark testing how well AI coding agents (Claude Code, Cursor, GitHub Copilot) can read web documentation. The test surfaces real failure modes—truncation, CSS layering, empty renders, tabbed content serialization—that cause agents to miss content during documentation workflows. Agents complete 10 tasks across problem-specific pages, then report which canary tokens they encountered.
