I've been having really good results from Jules, which is Google's gemini agent coding platform[1]. In the beta you only get 5 tasks a day, but so far I have found it to be much more capable than regular API Gemini.
Would you mind giving a little more info on what you're getting Jules to work on? I tried it out a couple times but I think I was asking for too large a task and it ended up being pretty bad, all things considered.
I tried to get it to add some new REST endpoints that follow the same pattern as the other 100 we have, 5 CRUD endpoints. It failed pretty badly, which may just be an indictment on our codebase...
I let Jules write a PR in my codebase with very specific scaffolding, and it absolutely blew it. It took me more time to understand the ways it failed to grasp the codebase and wrote code for a fundamentally different (incorrectly understood) project. I love Gemini 2.5, but I absolutely agree with the gp (pauldix) on their quality / scope point.
