Summary
During exercise two activity (Using GPT 4o):

When asking to search other projects in GitHub for similar projects, I added the context of my #(hashtag)Codebase, I got similar repositories, but when I asked for example 3 "brio" I got the following issue:
"I attempted to fetch details about the "brio" repository from its GitHub page but encountered an issue. You can visit the repository directly at brio to explore its features. Let me know if you'd like me to assist further!"

This happened on option two also
Changes
By changing the model from "GPT 4o" I switched to the newly release "Gemini 2.5 Pro" model which gives a larger context token space, and a slightly newer model recently released by Google with better results:

Additional context
Suggestion would be to update the exercise file to mention as a note that (other models) need to be considered based on their feature and purpose (E.g. Gemini, Claude, etc.)
