[BUG] 'Reveal in File Explorer' fails on Claude Code webview panel in WSL

What's Wrong?

When using Claude Code in VS Code with WSL, right-clicking and selecting "Reveal in File Explorer" on the Claude Code panel produces this error:

Unable to open webview-panel/webview-claudeVSCodePanel-d07f918e-7c68-4d95-bf11-e576f66319bd in the Windows explorer.

The action tries to reveal a virtual webview URI in Windows Explorer, which obviously doesn't resolve to a real filesystem path.

What Should Happen?

Either:

1. The "Reveal in File Explorer" option should not appear on the Claude Code webview panel (since it's not a file), or
2. If the option is shown, it should gracefully handle the case and not throw an error

Steps to Reproduce

1. Open VS Code connected to WSL
2. Open the Claude Code sidebar/panel
3. Right-click on the Claude Code panel tab
4. Click "Reveal in File Explorer"
5. Error: Unable to open webview-panel/webview-claudeVSCodePanel-<id> in the Windows explorer.

Is this a regression?

I don't know

Claude Code Version

2.1.72 (Claude Code)

Platform

Anthropic API

Operating System

Windows

Terminal/Shell

WSL (Windows Subsystem for Linux)

Additional Information

This may be a VS Code webview limitation rather than a Claude Code-specific bug, but since the webview is registered by the Claude Code extension, the extension could suppress or handle this context menu action.
