## Why crow_browser_fill_form is rated High

This tool performs browser automation by interacting with form fields in a web browser, simulating human input. It triggers external operations whose effects depend on the arguments provided (selectors and values). Depending on what form is filled and submitted, this could have significant downstream effects — submitting credentials, personal data, orders, etc.

From the tool's own definition: "Fill form fields with human-like typing. Accepts a map of selector -> value pairs."

## Use case

AI agents invoke crow_browser_fill_form to trigger actions in Crow. 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.
