Support IDE-level notifications for claude-code plugins (IntelliJ + VS Code)

Feature Request: Support IDE-level notifications for claude-code plugins (IntelliJ + VS Code)

Description

When using claude-code inside an IDE (e.g. IntelliJ IDEA with the plugin, installed globally via npm install -g), there is no built-in way to get notified when the tool is waiting for input or when a task is complete.

Many users resort to external scripts or workarounds for this. It would be more seamless if the IDE plugins themselves could handle notifications.

Proposal

• Add a mechanism in the plugins to listen for claude-code events such as:
• awaiting input
• task complete
• error occurred
• Forward these events to the IDE’s built-in notification system:
• IntelliJ → use the Notifications API (already integrates with system notifications).
• VS Code → use window.showInformationMessage / showWarningMessage / showErrorMessage, or the newer window.showNotification API.

Benefits

• Consistent notification experience directly in the IDE.
• System-level integration (Windows/macOS/Linux) handled automatically by the IDE.
• Users can configure and customize notifications via standard IDE settings.
• Reduces need for external tooling or hacks.

Example Use Cases

• Long-running code generation finishes → IDE shows a notification with a link to the result.
• claude-code pauses waiting for user input → notification prompts user attention.
• Error occurs in a background task → clear, actionable notification in the IDE.
