WHAT IT DOES

What browser_get-value does on Ruflo

AI agents call browser_get-value to retrieve information from Ruflo 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_get-value is rated Low

This tool retrieves data from web page input elements through browser automation. While it uses a browser engine (which could theoretically execute JavaScript), the explicit purpose is passive value extraction ('get value'). The description emphasizes use cases like scraping and reading before content delivery, with no mention of modifying state, executing commands, or side effects.

From the tool's definition Tool name is 'browser_get-value' and description states 'Get value of an input element'. The purpose is retrieving/querying data from browser DOM elements without modifying them.
