Greptile Overview

Greptile Summary

Added claude-4.5-opus model support across copilot system and commented out context usage indicator component.

Key Changes:

• Added claude-4.5-opus to model validation schemas, type definitions, and UI options
• Set claude-4.5-opus as enabled by default in user models configuration
• Commented out (not removed) ContextUsageIndicator component and claude-4.1-opus references

Issues Found:

• claude-4.1-opus remains in validation schemas and type definitions despite being commented out in UI and defaults, creating inconsistency
• ContextUsageIndicator import not removed despite component being commented out
• PR title says "remove" context usage indicator but code only comments it out

Confidence Score: 3/5

• This PR has logical inconsistencies that should be resolved before merging
• Score reflects inconsistent handling of claude-4.1-opus removal - it's commented out in some files but still present in validation schemas and type definitions, which will allow invalid model values to pass validation
• Pay close attention to apps/sim/app/api/copilot/chat/route.ts, apps/sim/lib/copilot/api.ts, and apps/sim/stores/panel/copilot/types.ts - these files still contain claude-4.1-opus in their schemas/types which creates inconsistency with the UI and defaults
