• The debug instruction debugpy --listen 127.0.0.1:5679 is incomplete and won't work as a standalone command. It should be invoked as part of a Python command (e.g., python -m debugpy --listen 127.0.0.1:5679 -m agentdev run <entrypoint>.py --port 8087). The current description separates these tasks but doesn't clarify how to actually run debugpy with agentdev, which could confuse users trying to set up debugging.

3. Key debug tasks: `agentdev run <entrypoint>.py --port 8087` starts the agent HTTP server, `debugpy --listen 127.0.0.1:5679` attaches the debugger, and the `ai-mlstudio.openTestTool` VS Code command opens the Agent Inspector UI
