What's Wrong?

I have light theme enabled for VS Code. Claude for VS code shows chat in light background but any code snippets do not respect the VS Code theme settings (light /dark). This stark contract is off-putting and sometimes hard to read.

<img width="1108" height="403" alt="Image" src="https://github.com/user-attachments/assets/d4446e28-205a-46e9-a15a-ddd1afdab743" />

What Should Happen?

The code snippet within the Claude chat window in VS Code should switch between light/dark based on theme settings.

extent analysis

TL;DR

The issue can likely be resolved by adjusting the theme settings or CSS styles in the Claude Code VS Code extension to respect the VS Code theme settings.

Guidance

  • Verify that the Claude Code extension is properly configured to inherit the VS Code theme settings.
  • Check if there are any custom CSS styles or overrides in the Claude Code extension that may be causing the code snippets to not respect the theme settings.
  • Try adjusting the theme settings in the Claude Code extension to see if it resolves the issue.
  • If the issue persists, consider reporting the bug to the Claude Code extension developers with more detailed information about the theme settings and CSS styles.

Example

No code snippet is provided as the issue does not imply a specific code change.

Notes

The issue may be specific to the Claude Code extension and its interaction with the VS Code theme settings. Further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Adjust the theme settings in the Claude Code extension to match the VS Code theme settings, as this may resolve the issue and provide a temporary fix until a more permanent solution is available.
