What's Wrong?

Environment:

• Claude Code version: 2.1.85
• IDE: JetBrains Rider
• OS: Windows 11 Enterprise

Describe the bug:
Claude Code displays a message prompting the user to install the "PyCharm plugin" even when JetBrains Rider is the active IDE and the plugin is already installed. The /ide command successfully connects to Rider (Connected to JetBrains Rider.), confirming the integration works, but the nag message still appears and incorrectly names PyCharm instead of Rider.

Steps to reproduce:

1. Install the Claude Code JetBrains plugin in Rider
2. Start Claude Code CLI with Rider open
3. Observe the nag message referencing "PyCharm plugin"

Expected behavior:
The message should either:

• Detect the specific JetBrains IDE (Rider) and name it correctly, or
• Use a generic "JetBrains plugin" label instead of hardcoding "PyCharm"

Actual behavior:
The message says "PyCharm plugin" regardless of which JetBrains IDE is in use.

Additional context:
/ide reports: Connected to JetBrains Rider. — so the IDE is correctly detected at the connection level but not in the plugin install prompt.

What Should Happen?

within Rider I would expect the nag message to say we need the rider plugin. Or since there is only one plugin for all JetBrains to not show Pycharm or a specific IDE but just JetBrains plugin for Claude

Install the plugin and restart Rider.

Observe that the nag message is still present even if the plugin is actually installed.

Worst the IDE integration is not enabled and cannot connect to the IDE
