One subtle behaviour of Claude that wasn't obvious to me: whilst each conversation is transient, permissions persist across conversations. So if you've given permission to run e.g. 'cargo test' or even 'cargo run', you need to be sure that all future invocations are safe too. You can see the current permissions with /permissions.

... and my third refactoring with Cursor changed some function calls that I didn't want it to modify. Subtle. I've had the most success with AI coding tools when I know exactly what I want the output to look like.

Difftastic uses the same parse tree for diffing and highlighting. This has a really nice side effect: you can spot parsing bugs from highlighting! It's subtle, but difftastic shows parentheses/braces in bold. I noticed that < and > weren't bold, and fixed the parser :)
