What problem does it solve? When console.log is not enough, this Skill lets you drive Node's built-in V8 inspector from the terminal to set real breakpoints, step through code, walk call stacks, dump local and closure scopes, and evaluate arbitrary expressions in paused frames. ## Core Features & Use Cases - Interactive REPL debugging: Use node inspect to set breakpoints, step in/over/out, watch expressions, and drop into a scoped REPL with zero installation. - Programmatic CDP automation: Script breakpoints, scope capture, CPU profiles, and heap snapshots 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 TypeScript project. Launch it with node --inspect-brk, attach the debugger, set a breakpoint in the suspect file, and inspect closure state that console.log cannot reach. ## Quick Start Ask the agent to debug a Node.js script by launching it with --inspect-brk, attaching node inspect, setting a breakpoint at the failing line, and inspecting the local variables when it pauses.
