Why do I need to restart Chrome and Claude Code after a fix?

Chrome registers native messaging hosts at startup, and the MCP bridge establishes its connection when Claude Code initializes. A full restart ensures the new configuration is active.

Can I use Claude.app Cowork and Claude Code CLI tools simultaneously?

No, they use incompatible socket formats and messaging configs. You must choose one and disable the other using the provided toggle script.

Why does Claude say 'Browser extension is not connected'?

This usually happens because Claude.app (Desktop) and Claude Code (CLI) use different native messaging hosts that conflict. This skill helps you disable the one you aren't using.

How do I handle version updates in Claude Code?

The skill includes a dynamic wrapper script that automatically points to the latest installed version of Claude Code, preventing hardcoded path errors.

Does this skill work on Windows or Linux?

No, this specific troubleshooting skill is designed for macOS as it relies on Library paths and AppleScript for process management.
