Greptile Overview

Summary

This PR enhances the Sim platform's copilot capabilities by adding contextual best practices to all block configurations. The implementation adds a new optional bestPractices field to the BlockConfig interface and populates it across 15+ core workflow blocks including Agent, API, Function, Memory, and various triggers.

Key Changes:

• Type System: Added optional bestPractices?: string field to BlockConfig interface in types.ts
• Block Configurations: Each block now includes tailored guidance covering common usage patterns, gotchas, and recommendations
• Metadata Tool: Updated get-blocks-metadata-tool.ts to extract and expose best practices through the copilot's metadata API
• Special Blocks: Added best practices for loop and parallel control flow blocks in the metadata tool

Best Practices Content Quality:

• Agent Block: Comprehensive guidance on tool restrictions, YAML syntax, and response format usage
• Function Block: Clear direction on execution modes (remote vs local) and variable referencing
• API Trigger: Detailed examples including production curl commands and variable access patterns
• Memory Block: Integration guidance with agent blocks for conversation persistence

The implementation follows a consistent pattern across all blocks, providing practical, actionable guidance that will help the copilot provide better contextual assistance to users building workflows.

Confidence Score: 4/5

• This PR is safe to merge with minor text corrections needed
• Score reflects clean type system changes and comprehensive documentation additions. Only minor typos in memory block prevent a perfect score. The implementation is consistent, follows established patterns, and enhances user experience without introducing breaking changes.
• apps/sim/blocks/blocks/memory.ts contains typos that should be fixed
