@stacky /c What's causing this null pointer exception?
@stacky /h Can you explain the last solution again?

You can copy the current debug context to your clipboard using the following commands:
Stacky: Copy Debug Context: Copies the debug context including variablesStacky: Copy Debug Context (No Variables): Copies the debug context without variables
These can be accessed via the Command Palette (Ctrl+Shift+P).
You can customize Stacky's behavior through VS Code settings:
stacky.model: Set the AI model to use (default: 'gpt-4o')stacky.debugContextMaxStacks: Maximum number of stack frames to include in the context (default: 5)stacky.debugContextMaxVars: Maximum number of variables to include per frame (default: 10)
- Provide an API for the model to enable more advanced output display to the user
- Enhance context filtering for more relevant information
