WHAT IT DOES

What browser_downloads does on Termux Browser Pilot

AI agents call browser_downloads to retrieve information from Termux Browser Pilot without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why browser_downloads is rated Low

This tool only queries and lists files in a directory, which is a passive data retrieval operation with no side effects. It does not create, modify, delete, or execute anything. The blast radius is minimal since an AI agent could only enumerate downloaded files, potentially learning what files have been downloaded but unable to cause harm through the tool itself.

From the tool's definition Tool description states it "List files in the browser download directory" - a read-only operation that retrieves information about existing downloads without modification, deletion, or execution.
