Bug Report: Claude Code Extension Unresponsive in VS Code

Environment:

• IDE: VS Code (latest)
• Extension: Claude Code for VS Code
• OS: Mac
• Duration: 2+ hours unresponsive

Issue:
Claude Code in VS Code has been completely unresponsive for over 2 hours. No responses are generated when submitting prompts — the extension appears to hang indefinitely.

Steps Taken:

1. Cleared conversation history — no improvement
2. Attempted /bug command — returns "No matching command" (appears unavailable in VS Code extension)
3. Fully uninstalled and reinstalled the Claude Code VS Code extension — issue persists
4. Restarted VS Code — no improvement

Expected Behavior:
Claude Code should respond to prompts within a reasonable time.

Actual Behavior:
No response is generated. The extension appears stuck/hung with no error messages displayed.

Request:
Please investigate. Also, it would be helpful if the /bug command were made available within the VS Code extension for easier in-context reporting.

What Should Happen?

Expected Behavior:

1. Upon submitting a prompt in the Claude Code VS Code extension panel, a response should begin streaming within a few seconds.
2. The extension should show a visible loading/thinking indicator while processing the request.
3. If the request fails (timeout, network error, rate limit, auth issue), a clear error message should be displayed to the user — not a silent hang.
4. The /bug command should be available within the VS Code extension to allow in-context bug reporting with auto-attached logs and environment info.
5. After a fresh reinstall, any corrupted state or cache should be cleared, and the extension should return to a working state.

Error Messages/Logs

Nothing

Steps to Reproduce

Steps to Reproduce:

1. Open VS Code with the Claude Code extension installed and authenticated.
2. Open the Claude Code panel (via sidebar or command palette).
3. Type any prompt (e.g., "Hello" or "Explain this file") and press Enter.
4. Observe: No response is generated. The extension hangs indefinitely with no loading indicator, error message, or timeout.
5. Wait 5+ minutes — still no response.
6. Clear the conversation using the Clear Chat option — retry the prompt. Same result: no response.
7. Try typing /bug in the Claude Code input — returns "No matching command" instead of opening a bug report flow.
8. Fully uninstall the Claude Code extension from VS Code.
9. Restart VS Code.
10. Reinstall the Claude Code extension from the Marketplace and re-authenticate.
11. Open the Claude Code panel and submit a prompt — issue persists, still no response.

Frequency: 100% reproducible. Every prompt attempt over the last 2+ hours has failed silently.

Additional Context:

• No error messages shown in the Claude Code panel.
• VS Code Output panel (Claude Code channel) logs can be attached if needed.
• Internet connection is stable; other extensions and web browsing work fine.
• Issue may be specific to VS Code extension — terminal CLI not yet tested.
