What export_query_to_csv does on Cowork Bench
AI agents invoke export_query_to_csv to trigger actions in Cowork Bench. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why export_query_to_csv is rated High
This tool executes a SQL query (Execute category) and writes results to a file (Write category). Since Execute > Write in severity ranking, it is classified as Execute. The ability to run arbitrary SELECT queries and write output to the filesystem poses high risk if misused — an agent could exfiltrate sensitive data or write files to unintended locations.
