What's Wrong?

Bug Report: PyCharm plugin sends notifications with empty app_name

Summary

On Linux (GNOME), notifications from Claude Code in PyCharm show as "Unknown App" because the D-Bus notification app_name field is empty.

Environment

• OS: Ubuntu (GNOME/Wayland)
• IDE: PyCharm Professional
• Claude Code: PyCharm plugin

Steps to Reproduce

1. Open Claude Code in PyCharm terminal
2. Start a task that will prompt for input
3. Switch to another window
4. When Claude sends a notification ("Claude is waiting for your input"), check the notification center

Expected Behavior

Notification should show "PyCharm" or "Claude Code" as the source app, and clicking the notification should bring PyCharm to the front.

Actual Behavior

• Notification shows "Unknown App"
• Clicking the notification does not bring PyCharm to the front

Debug Information

D-Bus monitor output shows empty app_name (first string parameter):

method call sender=:1.93 -> destination=org.freedesktop.Notifications
   string ""                                    <-- app_name is EMPTY
   uint32 4
   string "pycharm-professional_dialog-information"
   string "Claude Code"
   string "Claude is waiting for your input"

Suggested Fix

Set the app_name parameter in the D-Bus Notify call to "PyCharm" or "Claude Code" instead of an empty string.
