Overview

Expert skill for implementing Debug Adapter Protocol for debugger integration.

Capabilities

Implement DAP message handling
Implement breakpoint management (line, conditional, function)
Implement stepping (step in/out/over, continue)
Implement stack trace retrieval
Implement variable inspection and watch expressions
Implement expression evaluation in debug context
Handle launch vs attach configurations
Implement exception breakpoints
Support multi-threaded debugging

Target Processes
