Feature request: VS Code terminal integration tool to send commands to integrated terminal

Summary

Add a tool that allows Claude Code to send commands to the user's VS Code integrated terminal session.

Use Case

When Claude Code runs git checkout <branch>, the branch switch happens in Claude's shell context. However, the user's VS Code integrated terminal is a separate shell session and still shows the old branch in its prompt.

This creates confusion because:

• Claude reports "Switched to branch X"
• User's terminal prompt still shows branch Y
• User has to manually run git checkout X in their terminal to sync

Proposed Solution

Add a VS Code terminal tool that calls vscode.window.activeTerminal.sendText() to execute commands in the user's terminal session.

Example API:

Tool: VSCodeTerminal
Parameters:
  - command: string (the command to execute)
  - execute: boolean (whether to press Enter after sending, default true)

Benefits

• Seamless branch switching during PR reviews
• Terminal stays in sync with Claude's operations
• Better UX for any workflow involving directory/branch changes

Workaround (Current)

We've documented in our skills to inform users they need to manually run the git command in their terminal, but this is friction that could be eliminated.

Additional Context

This would be particularly valuable for:

• PR review workflows (switching to PR branch)
• Multi-repo operations
• Any skill that changes git state
