I want to make a Computer Use Agent using Claude 🤖

I’m a 3rd-year CS Engineering student, and I want to build my own personalized Computer Use Agent, somewhat like Comet, but specifically designed around my college portal.

The idea is simple: a Chrome extension that I can direct in natural language, and it actually uses my browser for me — navigating the portal, understanding pages, and completing tasks.

My main use case? College assignments and complex quizzes that require navigating multiple pages, understanding questions/context, and interacting with the portal.

I want it to be highly personalized to my workflow rather than a generic browser agent.

Thinking of building this with Claude. Has anyone tried something similar? What would be the best approach/architecture?
