What a11y_accept_baseline does on A11y Render Gate
AI agents call a11y_accept_baseline to retrieve information from A11y Render Gate without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why a11y_accept_baseline is rated Low
Even though a11y_accept_baseline only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
