Problem Statement

Each Bash command requires manual approval. Complex commands (long, multi-line, piped, escaped) render as a single unformatted line in the approval prompt, making them unreadable. Reviewing the command before approving is effectively impossible - it reads like unformatted code.

Proposed Solution

Display Bash commands in the approval prompt formatted, so they can be read like code. I understand that's not what everyone would want, so let's make it configurable.

---
btw, if a formatter gets added, might be a good opportunity to make it pluggable and exposed as a config option so that users can develop their own formatters.

Alternative Solutions

Couldn't find one. There are formatters for raw Claude JSON output, but they don't work with the interactive TUI.

Priority

High - Significant impact on productivity
