I just tried Claude Code www.anthropic.com/news/claude-... in a few exercises from Exercism... I just used a base prompt like "Here's the readme, here's the main module, resolve," then the agent checked test files, and for all exercises, the resulting code passed all tests. Incredible.

Heheh Of course, these are simple exercises that Cursor/Windsurf/{IDE} can resolve as well, I haven’t tried in a bigger code base

Do you feel the agent has "awareness" of how much these sizable projects can cost you? You can have thousands of files; how does the agent know when not to upload lots of files to save dollars (without explicitly telling it which files to work on)?
