! <command> does not open interactive editors (e.g. vim) in the terminal

What's Wrong?

When using the ! prefix to run shell commands in Claude Code, commands that require an interactive TTY (such as git commit --edit, which opens $EDITOR/vim) do not work -- the
editor never appears. The command runs silently in a non-interactive shell and the editor is effectively swallowed.

Expected behaviour: ! git commit --edit opens the configured editor (e.g. vim) in the Claude Code terminal, allowing the user to edit the commit message interactively.

Actual behaviour: No editor appears. The command completes without prompting for input.

Workaround: Open a separate terminal and run git commit --edit there, or use git commit -m "..." --edit from a proper TTY.

Platform: Linux (Ubuntu), shell: bash

What Should Happen?

Expected behaviour: ! git commit --edit opens the configured editor (e.g. vim) in the Claude Code terminal, allowing the user to edit the commit message interactively.

Steps to Reproduce

1. ask claude to generate a commit message
2. then ask claude how to edit it to make changes
3. claude then come up with ! git commit --edit
4. when you paste that in as a command it gets swallowed and no editing happens
