Pros
- Lives in the terminal and in the editor, so it can edit files, run tests, and handle git without a separate chat window
- Included on every paid Claude plan, not a second coding seat
Cons
- Desktop app needs a paid Claude subscription
- Usage is shared with Claude chat, so a long coding session burns the same pool
