Debug Adapter Protocol Skill

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

• debugger-adapter-development.js
• lsp-server-implementation.js
• interpreter-implementation.js
• bytecode-vm-implementation.js

Dependencies

• DAP specification
• vscode-debugadapter libraries

Usage Guidelines

1. Message Handling: Implement robust JSON message parsing and validation
2. Breakpoints: Support line, conditional, and function breakpoints
3. Stepping: Implement all stepping modes with correct semantics
4. Variables: Implement lazy variable expansion for performance
5. Evaluation: Support expression evaluation in stopped state
