How to build a coding agent

Why are any of the tools beyond the bash tool required?

Surely listing files, searching a repo, editing a file can all be achieved with bash?

Or is this what's demonstrated by https://news.ycombinator.com/item?id=45001234?

Technically speaking, you can get away with just a Bash tool, and I had some success with this. It's actually quite interesting to take away tools from agents and see how creative they are with the use.

One of the reasons why you get better performance if you give them the other tools is that there has been some reinforcement learning on Sonne with all these tools. The model is aware of how these tools work, it is more token-efficient and it is generally much more successful at performing those actions. The Bash tool, for instance, at times gets confused by bashisms, not escaping arguments correctly, not handling whitespace correctly etc.
