ToolIcon Switch Statement Return Bug Fixed

Perfect! I can see the issue. The current GeminiToolCall interface is too generic - it has a catch-all args object that doesn't properly type each specific tool call. Looking at the gemini-thread component, I can see there are 6 different tool calls with different argument structures.

Let me create a plan to add specific interfaces for each tool call:

Perfect! I've analyzed the gemini-thread component and created proper type-safe interfaces in gemini.ts. Here's what I did:

Analysis of gemini-thread.tsx

The component handles 6 different tool calls: 1. write_file - Creates/writes a file 2. list_directory - Lists directory contents 3. read_file - Reads a file 4. write_todos - Writes a todo list 5. replace - Replaces file content 6. runshellcommand - Executes a shell command

Each has different argument structures that weren't properly typed.

Changes Made to gemini.ts

Created a type-safe union type with specific interfaces for each tool call:

• WriteFileToolCall - args: { file_path, content }
• ListDirectoryToolCall - args: { dir_path }
• ReadFileToolCall - args: { file_path }
• WriteTodosToolCall - args: { todos[] }
• ReplaceToolCall - args: { file_path, new_string, old_string }
• RunShellCommandToolCall - args: { command, description }

All extend a BaseToolCall interface that contains common properties (id, status, timestamp, displayName, description, renderOutputAsMarkdown, result).

The GeminiToolCall type is now a discriminated union, so TypeScript will properly narrow the args type based on the name property in gemini-thread.tsx's if/else chain.
