Greptile Overview

Greptile Summary

Improved chat UI type safety, documentation, and visual presentation through comprehensive TSDoc additions, TypeScript type improvements (any → unknown/proper types), and refined styling adjustments.

• Replaced all any types with proper TypeScript types (unknown, ChatFile, ProcessedAttachment)
• Added comprehensive TSDoc comments to all functions, interfaces, and parameters throughout chat components
• Updated empty state message from technical "Workflow input: <start.input>" to user-friendly "No messages yet"
• Refined badge styling in OutputSelect (consistent rounded-[6px], text-[12px], whitespace-nowrap)
• Reduced default chat width from 330px to 305px for better layout fit
• Added proper type guards and runtime checks in handleWorkflowResponse

All changes align with the project's architecture guidelines for type safety, documentation standards, and consistent styling patterns.

Confidence Score: 5/5

• This PR is safe to merge with no risks
• The changes are purely improvements to code quality without altering functionality. All modifications enhance type safety (replacing any with proper types), add documentation (comprehensive TSDoc), and make minor UI refinements (better empty state message, consistent badge styling, width adjustment). No logical changes, no new features that could introduce bugs, and all changes follow established project patterns.
• No files require special attention
