Does it have different goals than: https://aider.chat ?
I still think a tool like aider is where AI is heading, these "agents" are built upon running systems that are 15% error prone and just compound errors with little ability to actually correct them.
Aider is more understandable to me, doing small chunks of work, but it won't do a google search to find usage, etc. It depends on you to choose which files to put in context and so on.
I wish aider had a bit more of the self directedness of this, but API calls and token usage would be greatly increased.
Edit: or maybe an agency loop like this steering aider based on a larger goal would be useful?
