How to use ego (lite) with Cursor

Cursor can use ego-browser to work in an ego (lite) Space on Windows. The full recording follows a Reddit research task from Cursor through the final result.

The example asks Cursor to find a popular Reddit post from the past week, open it, and return the details visible on the page in a table.

Before you start: install ego (lite)

Install ego (lite) on Windows and finish setup. Open Cursor on the same computer and start a local Agent chat. If you need help with the browser setup, begin with Quick start.

Check that ego-browser is available in Cursor. If it is missing, finish ego (lite) setup, restart Cursor, and check again.

Step 1: Set Run Everything

Open Cursor's Settings > Agents. Under Execution and Approvals, open Run Mode and select Run Everything. The recording shows this option in Cursor on Windows. It lets Cursor launch ego (lite) and run the local browser task without stopping for approval at each command.

Step 2: Load the ego-browser skill

Type /ego-browser in the Cursor Agent input box and select the skill. Then describe the browser task you want Cursor to run.

Step 3: Let Cursor work in the browser

Cursor opens Reddit in an ego (lite) Space, finds a post, and reads the page. You can switch to the agent Space to follow its work while your own tabs stay where they are.

Step 4: Check the result

Cursor returns a table with the post title, subreddit, link, posting date, and visible engagement figures. In the recording, Reddit does not show a view count, so Cursor marks it not shown. Open the linked post to check the figures before using the result.

Troubleshooting

ego-browser is missing

Finish ego (lite) setup, close Cursor, and open it again. Type /ego-browser in a new local Agent chat and look for the skill.

Cursor cannot open ego (lite)

Check that ego (lite) is installed on the same Windows computer and review Settings > Agents > Execution and Approvals > Run Mode. The recording uses Run Everything. Review any permission prompt before trying the task again.

Reddit asks you to sign in

Open the agent Space in ego (lite), complete the sign-in or verification yourself, and then ask Cursor to continue. Keep passwords and verification codes out of the task prompt.
