The Monitoring tool window collects runtime data every time an application runs, allowing the AI agent to find bottlenecks and link them to code using the Analyze with AI action, which sends a prompt to the agent to begin the investigation. The agent uses the dottrace-analyze skill to show where time was spent, follow hot paths in code, and provide useful performance insights in the chat. This feature requires Windows, dotUltimate or the All Products Pack, and the AI Assistant plugin. The widget fix addresses issue RIDER-143160, where clicking its taskbar icon with display scaling below 175% failed to open the widget, and updates are available from the IDE, Toolbox App, or website."

The widget fix addresses issue RIDER-143160, where clicking its taskbar icon with display scaling below 175% failed to open the widget, and updates are available from the IDE, Toolbox App, or website.

## Approach / What changed

The update introduces AI performance analysis in the Monitoring tool window, where the agent uses the dottrace-analyze skill to analyze runtime data and provide insights.

## Takeaways

- The AI performance analysis feature requires Windows, dotUltimate or the All Products Pack, and the AI Assistant plugin.
- The agent uses the dottrace-analyze skill to find bottlenecks, show time distribution, and follow hot paths in code.
- The AI Agent Setup widget fix resolves an issue where clicking its taskbar icon with display scaling below 175% failed to open the widget.

## FAQ

### How does the AI performance analysis work?

The Monitoring tool window collects runtime data, and using the Analyze with AI action sends a prompt to the agent, which uses the dottrace-analyze skill to show where time was spent and follow hot paths in code.

### What are the requirements for the AI performance analysis feature?

It requires Windows, dotUltimate or the All Products Pack, and the AI Assistant plugin.

### What issue was fixed in the AI Agent Setup widget?

The widget failed to open when clicking its taskbar icon with display scaling below 175% on Windows; this is now fixed.
