Problem Statement

When Claude Code proposes an edit and opens the side-by-side diff view, the file is not revealed/selected in the VS Code explorer sidebar. The diff tab shows [Claude Code] filename indicating it's a virtual document, which bypasses VS Code's explorer.autoReveal setting.

Current behavior:

• Claude proposes an edit → diff view opens in editor
• Explorer sidebar does not change — the file's location in the tree is not shown

Proposed Solution

Desired behavior:

• Claude proposes an edit → diff view opens in editor
• The target file is also revealed/selected in the explorer sidebar, so you can see where it lives in the project structure

Why this is useful:

• Provides spatial context for the file being edited, especially in unfamiliar codebases
• Matches the UX of normal file opens in VS Code
• Helps when reviewing multiple edits across different directories

Suggested implementation:
When showing the diff, call something like:

vscode.commands.executeCommand('revealInExplorer', targetFileUri);
