Greptile Overview

Greptile Summary

This PR adds Perplexity search endpoint support, extending the existing Perplexity integration beyond chat to include web search functionality.

Key Changes

• Added new perplexity_search tool with support for advanced filtering (domain, country, recency, date ranges)
• Updated Perplexity block with operation dropdown to switch between Chat and Search modes
• Refreshed model list to include current Perplexity models (Sonar, Sonar Pro, Sonar Deep Research, Sonar Reasoning variants)
• Added conditional field rendering based on selected operation
• Implemented domain filter parsing from comma-separated string to array
• Updated documentation to reflect new search capabilities

Implementation

The implementation follows established patterns in the codebase, with proper TypeScript typing and consistent structure matching other search tools like Tavily and Exa. The block config properly handles conditional field display and parameter transformation for both operations.

Confidence Score: 4/5

• This PR is safe to merge with minor considerations
• The implementation is well-structured and follows existing patterns. No critical bugs found. Score reduced from 5 due to lack of error handling for malformed API responses and no validation for numeric constraints (max_results 1-20, max 20 domains)
• Pay attention to apps/sim/tools/perplexity/search.ts for potential runtime errors with malformed API responses
