Agentic debugging

Bundled skills help AI agents use IDE tools more effectively by providing predefined workflows instead of forcing the agent to figure out the correct sequence of actions on its own. RubyMine includes the rubymine-debugger skill, which lets compatible AI agents use the IDE's debugging capabilities autonomously.

Instead of manually stepping through code and inspecting runtime state yourself, you can describe the problem in natural language and let the agent perform much of the investigation for you. Using the RubyMine debugger, agents can launch or continue debug sessions, set breakpoints, inspect variables and call stacks, evaluate expressions, and analyze application behavior at runtime. This helps them identify issues that are difficult to understand from source code and logs alone.

Enable the debugger skill

Open the Settings dialog Ctrl+Alt+S and go to Tools | AI Assistant | Skills.
Find ruby-debugger under Bundled kills and select the Enable skill checkbox.
Click OK to apply the changes.

Debug your code with an agent using the enabled skill

Click the AI Chat icon on the right-hand toolbar to open the AI Chat tool window.
Describe the problem you want to investigate in natural language and ask the agent to debug your code. For example:
Debug why the create action in PostsController saves a post even when the title is blank.
Click the Send icon or press Enter.
The agent will launch the rubymine-debugger skill.
The agent uses the debugger as part of its investigation workflow. It can set breakpoints, launch or continue a debug session, inspect variables and the call stack, and evaluate expressions to analyze the application behavior at runtime, and then report what it finds.
