Problem Statement

When Claude Code shows me a diff of a markdown file, it presents both bold and removed lines in red. Being the same color, it's easy to think Claude is trying to remove the lines containing bold text, even if the lines are only being shown as context. An example:

<img width="1351" height="118" alt="Image" src="https://github.com/user-attachments/assets/dcbb2e90-7a97-4e6f-9417-acf0863723bb" />

My silly brain thought Claude was trying to remove lines 133-135 in addition to 136, when it was only trying to remove line 136. Please help those of us with silly brains.

Proposed Solution

Please consider using a different color (other than red or green) to present diffs of markdown files.
