What's Wrong?

I just installed claude code (the native installer, not the node.js one) on a Mac running 15.7.4, using instructions provided by claude. The install went fine, but ~/.local/bin wasn't added to PATH. I am using bash as my login shell.

Claude suggested I report this bug here.

What Should Happen?

The installer should have edited my .bashrc but it didn't.
