Greptile Overview

Summary

This PR implements comprehensive improvements to the copilot system, focusing on fixing JSON parsing edge cases and enhancing model management capabilities. The changes span multiple areas:

Database Schema Enhancement: Adds a new copilot_enabled_models JSONB column to the settings table, allowing users to configure which AI models are enabled for their copilot experience. This includes a complete database migration (0096) and SSL configuration improvements across all database connection points.

Copilot Model Management: Introduces a sophisticated model preference system where users can selectively enable/disable OpenAI and Anthropic models. The implementation includes a new API endpoint (/api/copilot/user-models) for managing these preferences, integration with the copilot store for state management, and a redesigned settings UI that combines API key management with model selection.

JSON Parsing Improvements: Addresses multiple edge cases in workflow processing that were causing issues for the copilot. Key fixes include:

• Enhanced block output resolution that properly handles trigger mode vs normal mode
• Improved workflow edit sequence computation with delta-based updates and duplicate operation prevention
• Better JSON sanitization for responseFormat, conditions, and tools
• Fixed parent-child relationship handling in workflow diffs
• Robust input format validation to prevent null/undefined errors

UI/UX Enhancements: The copilot interface receives several improvements including responsive design with dynamic width handling, terminology changes from "MAX" to "Lite" mode for better user understanding, prefetching optimizations in settings navigation, and broader availability of copilot features across deployment environments (no longer restricted to hosted-only).

Infrastructure Improvements: Standardizes SSL configuration across all PostgreSQL connections with support for multiple SSL modes (disable, prefer, require, verify-ca, verify-full) and custom CA certificate handling, replacing previous boolean SSL toggles.

The changes integrate well with the existing codebase architecture, following established patterns for Zustand store management, API design, and database migrations. The copilot system now has more robust data processing capabilities and provides users with granular control over AI model preferences.

Confidence score: 4/5

• This PR addresses important edge cases and introduces valuable copilot functionality with mostly safe changes
• Score reflects some concerns around validation in the user-models API endpoint, potential dependency issues in create-menu, and security considerations in JSON sanitization
• Pay close attention to apps/sim/app/api/copilot/user-models/route.ts and apps/sim/app/workspace/[workspaceId]/w/components/sidebar/components/create-menu/create-menu.tsx for validation and dependency issues
