Greptile Summary

Added React Grab debugging tool integration, workflow tool icon rendering, and combobox search query clearing. The PR introduces a feature-flagged React Grab integration for UI debugging in development environments, adds visual support for workflow tools with proper icon rendering, and fixes a UX issue where search queries persisted when reopening the combobox.

Key Changes:

• Added REACT_GRAB_ENABLED environment variable and isReactGrabEnabled feature flag (dev-only)
• Integrated React Grab scripts from unpkg CDN with conditional loading in root layout
• Added isWorkflowTool handling with WorkflowIcon and purple background color in tool input component
• Fixed combobox to clear search query on close (Escape, blur, selection) preventing stale queries on reopen

Issues Found:

• Critical: Incomplete isWorkflowTool checks in tool-input.tsx - workflow tools will incorrectly execute code paths meant for standard tools (getToolIdForOperation, getToolParametersConfig, toolRequiresOAuth, hasMultipleOperations) causing potential runtime errors

Confidence Score: 2/5

• This PR has critical logic bugs that will cause runtime errors for workflow tools
• While the React Grab integration and combobox fixes are solid, the workflow tool implementation is incomplete. Multiple conditional branches check !isCustomTool && !isMcpTool but omit !isWorkflowTool, causing workflow tools to incorrectly execute standard tool logic paths. This will likely cause errors when users interact with workflow tools.
• Pay close attention to apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx - the workflow tool handling is incomplete and needs all conditional branches updated

Important Files Changed

Filename	Overview
apps/sim/lib/core/config/feature-flags.ts	Added isReactGrabEnabled feature flag that enables React Grab only in dev mode
apps/sim/app/layout.tsx	Conditionally loads React Grab scripts from unpkg CDN when feature flag is enabled
apps/sim/components/emcn/components/combobox/combobox.tsx	Added search query clearing when combobox closes to prevent stale queries on reopen
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx	Added workflow tool icon rendering support, but missing isWorkflowTool checks in multiple conditional branches causing potential bugs

1. apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx, line 2208-2211 (link)

   logic: Missing !isWorkflowTool check. Workflow tools will incorrectly call getToolIdForOperation which is meant for standard tools.

2. apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx, line 2214-2217 (link)

   logic: Missing !isWorkflowTool check. Workflow tools will incorrectly attempt to fetch tool parameters config.

3. apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx, line 2275 (link)

   logic: Missing !isWorkflowTool check. Workflow tools will incorrectly be checked for multiple operations.

4. apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx, line 2269-2272 (link)

   logic: Missing !isWorkflowTool checks. Workflow tools will incorrectly be processed as standard tools in these conditionals.
