Greptile Overview

Greptile Summary

This PR adds workflow, knowledge base, and function tools as agent block capabilities, along with keyboard navigation fixes in the tool input component.

Key Changes:

• Added workflow_executor tool with dynamic input field mapping that fetches workflow schemas at runtime
• Made createLLMToolSchema async to support dynamic schema generation with 5-minute caching
• Replaced Select with Combobox for better UX and added workflow/KB/document selector wrappers
• Fixed keyboard navigation by extracting useCommandKeyDown hook and using CommandKeyboardWrapper
• Added user-or-llm visibility to multiple tool params (knowledge, function) for proper LLM schema generation
• Added items property support for array parameters with nested type definitions

Implementation Quality:

• Dynamic workflow input field fetching with proper caching reduces API calls
• Conditional rendering logic using not: true correctly shows input mapper when workflow is selected
• Proper separation of concerns between UI components and data fetching
• Tests updated to handle async schema generation

Confidence Score: 4/5

• This PR is safe to merge with minor attention to the large tool-input.tsx refactor
• The implementation is well-structured with proper async handling, caching, and type safety. The keyboard navigation fix properly delegates to context. Main complexity is in tool-input.tsx which has a large refactor but maintains existing patterns. Dynamic workflow schema generation is well-implemented with error handling.
• apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx - large refactor with many new selector wrappers, verify all edge cases are handled

File Analysis

Filename	Score	Overview
apps/sim/tools/params.ts	4/5	Added workflow_executor special handling with dynamic schema generation for workflow input fields. Made createLLMToolSchema async to support dynamic schema enrichment. Added workflow input field caching (5min TTL).
apps/sim/tools/workflow/executor.ts	4/5	Changed workflow executor to call workflow execution API directly. Added user-or-llm visibility to params. Updated description to guide LLM on proper input mapping. Improved response transformation to handle new API format.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx	3/5	Major refactor: replaced Select with Combobox, added WorkflowSelectorSyncWrapper and WorkflowInputMapperSyncWrapper, added KnowledgeBaseSelectorSyncWrapper and DocumentSelectorSyncWrapper, fixed keyboard navigation by using useCommandKeyDown hook with CommandKeyboardWrapper.
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/components/tool-command/tool-command.tsx	4/5	Exported useCommandKeyDown hook, added handleKeyDown to context, removed onKeyDown from div (moved to consuming components), added auto-scroll to active item, simplified filtering to not sort by score.
