Greptile Overview

Greptile Summary

Changed the system_message() style in src/cortex-core/src/style.rs from muted gray (TEXT_MUTED #486581) to error red (ERROR #FF6B6B). This makes all system messages display in red with italic styling.

Key Issues:

• The system_message() style is used for BOTH error messages AND informational messages throughout the codebase
• Examples of non-error usage include: "Resumed session: {id}", "No provider configured. Use /provider...", command output messages
• Displaying all system messages in red creates a misleading UX where informational messages appear as errors
• As noted in the PR description, this is a demo PR and should not be merged without separating error-specific styling from general system messages

Recommendation:

Create a dedicated error_message() style function for actual errors, keeping system_message() for informational system messages. This would allow proper semantic color coding based on message severity.

Confidence Score: 3/5

• This PR should NOT be merged as-is due to UX issues with non-error messages appearing as errors
• The change is syntactically correct and won't cause runtime errors, but creates a logical UX problem where all system messages (including informational ones) display in red, misleading users about message severity
• Pay close attention to src/cortex-core/src/style.rs - the change affects all system messages throughout the application

system_message() is used for both errors AND informational messages (e.g., "Resumed session: {id}", command output). Making all system messages red misleads users into thinking informational messages are errors.

Consider creating a separate error_message() style as the PR description suggests, or distinguish message types at the call site.
