JetBrains Rider plugin incompatible with latest Claude Code version

[LukasMerz]

Description

The Claude Code plugin for JetBrains Rider is not compatible with the newest Claude Code version. IDE detection fails even when the plugin is installed and enabled.

Environment

• IDE: JetBrains Rider (latest version)
• OS: Windows
• Claude Code: Latest version (installed via npm/brew)

Steps to Reproduce

1. Install Claude Code plugin in Rider (Settings → Plugins → Marketplace)
2. Ensure plugin is enabled
3. Restart Rider
4. Run claude from Rider's integrated terminal
5. Run /ide command

Expected Behavior

Claude Code should detect Rider as the active IDE and enable IDE integration features.

Actual Behavior

IDE detection fails. The /ide command does not recognize Rider.

Additional Context

• Plugin is installed and enabled (verified in Settings → Plugins)
• Rider has been restarted after plugin installation
• Claude is in PATH and runs correctly from integrated terminal
• claude doctor does not show Rider as a detected IDE

Possible Cause

The plugin may need to be updated to support breaking changes in the latest Claude Code version's IDE detection mechanism.
