Greptile Overview

Greptile Summary

This PR updates the Kalshi and Polymarket prediction market integrations with enhanced API coverage and improved data structures.

Kalshi Updates:

• Added V2 variants of all 17 Kalshi tools that provide complete API response structures instead of simplified outputs
• V2 tools include additional parameters like countFp (fractional contracts), cancelOrderOnPause, and subaccount support
• Updated block configuration to use versioned tool selector pattern, defaulting to V2 tools
• V1 tools remain available for backward compatibility

Polymarket Updates:

• Added 3 new tools: get_activity (on-chain user activity), get_leaderboard (platform rankings), and get_holders (market holder information)
• Enhanced existing tools (get_positions, get_trades) with richer data including user profiles, transaction hashes, and detailed PnL metrics
• Updated type definitions to match current Polymarket Data API structure
• Added comprehensive block UI configurations for new operations

Documentation:

• Updated both Kalshi and Polymarket documentation with detailed field descriptions
• Changed Kalshi docs to reference kalshi_v2 block type

All tools follow established patterns for authentication (user-only visibility for API keys), error handling, and response transformation. The changes maintain backward compatibility by keeping V1 Kalshi tools alongside V2 variants.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• All changes follow established patterns for tool implementation with proper TypeScript types, error handling, and authentication. V2 Kalshi tools maintain backward compatibility. New Polymarket tools match API specifications. No breaking changes detected.
• No files require special attention
