Claude 3.7 Sonnet and Claude Code

Just started playing with the command-line tool. First reaction (after using it for 5 minutes): I've been using `aider` as a daily driver, with Claude 3.5, for a while now. One of the things I appreciate about aider is that it tells you how much each query cost, and what your total cost is this session. This makes it low-key easy to keep tabs on the cost of what I'm doing. Any chance you could add that to claude-code?

I'd also love to have it in a language that can be compiled, like golang or rust, but I recognize a rewrite might be more effort than it's worth. (Although maybe less with claude code to help you?)

EDIT: OK, 10 minutes in, and it seems to have major issues doing basic patches to my Golang code; the most recent thing it did was add a line with incorrect indentation, then try three times to update it with the correct indentation, getting "String to replace not found in file" each time. Aider with claude 3.5 does this really well -- not sure what the counfounding issue is here, but might be worth taking a look at their prompt & patch format to see how they do it.

If you do `/cost` it will tell you how much you've spent during that session so far.

hi! You can do /cost at any time to see what the current session has cost
