What problem does it solve? When console.log is not enough, this Skill lets you drive Node's built-in V8 inspector programmatically from the terminal, giving you real breakpoints, step in/over/out, call-stack walking, scope dumps, and expression evaluation in paused frames. ## Core Features & Use Cases - Interactive REPL Debugging: Use the built-in node inspect CLI to set breakpoints, step through code, watch expressions, and drop into a scoped REPL with zero installation. - Programmatic CDP Automation: Script breakpoint placement, scope capture, and expression evaluation via chrome-remote-interface for non-interactive or agent-driven debugging. - Attach to Running Processes: Enable the inspector on live Node processes with SIGUSR1 and attach by PID or WebSocket URL, including Ink-based TUI apps and Vitest test runs. - Use Case: A Vitest test fails in a tsx project and you need intermediate state. Launch the test with --inspect-brk, attach node inspect, set a breakpoint in the suspect file, and inspect locals and closures in the paused frame. ## Quick Start Ask the agent to run your Node script with --inspect-brk, attach the node inspect debugger, set a breakpoint at the failing line, and print the local variables when it pauses.
