What's Wrong?

Claude Code Native does not detect PHPStorm as an available IDE, showing the message "No available IDEs detected. Please install the plugin and restart your IDE." This prevents using the IDE-based diff approval workflow, forcing users to approve all changes through the terminal instead.

Claude Code successfully modifies files, but without IDE detection, users cannot review and approve changes using PHPStorm's diff viewer, which is the preferred workflow for reviewing code modifications.

What Should Happen?

Claude Code should detect PHPStorm when it's running and allow users to approve file changes through PHPStorm's diff interface, similar to how it works with VS Code. The IDE integration should enable visual diff review and approval within the familiar PHPStorm environment.

Error Messages/Logs

No available IDEs detected. Please install the plugin and restart your IDE.

Steps to Reproduce

1. Install Claude Code Native
2. Open PHPStorm with a project
3. Run a Claude Code command that modifies files (e.g., claude "refactor this function")
4. When prompted to approve changes, observe the message "No available IDEs detected. Please install the plugin and restart your IDE."
5. Changes must be approved via terminal instead of through PHPStorm's diff viewer
6. File modifications do work, but IDE integration for reviewing changes does not

Note: Running /ide command shows PHPStorm in the list of detected IDEs, but Claude Code cannot establish or maintain a connection to it - the connection drops immediately/automatically.
