## Why browser_headers_clear is rated Critical

This tool irreversibly removes all custom HTTP headers and eliminates fetch/XHR hooks from the browser session. While not deleting persistent data like files or records, the action of clearing all headers and removing hooks cannot be undone without reconfiguring them, making it a destructive reset of browser network interception configuration. Misuse could break ongoing authenticated sessions or monitoring setups.

From the tool's own definition: "Clear all custom HTTP headers and remove fetch/XHR hooks"
