Hey @Govind_Arora  
A rule in AGENTS.md is just guidance the model weighs, so on website projects it often opens the browser anyway. It’s not something you misconfigured.

To stop it completely: open Cursor Settings → Browser (or search “Browser Automation”), set Browser Automation to Off, then start a new chat. That removes the browser tools from the agent entirely, on any model.

If you’d rather keep it available but on-demand, leave it on and turn on Browser Protection just below - the agent then has to ask before any browser action. More here: [Browser | Cursor Docs](https://cursor.com/docs/agent/browser)

Let me know if it still opens after a fresh chat.
