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 the built-in node inspect CLI to set breakpoints, step in/over/out, watch expressions, and drop into a scoped REPL with zero installation. - Programmatic CDP automation: Script breakpoint management, scope capture, CPU profiles, and heap snapshots through chrome-remote-interface for non-interactive agent loops. - 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 on the suspect line, and inspect closure variables directly in the paused frame. ## Quick Start Ask the agent to run your failing Node script with --inspect-brk, attach the node inspect debugger, set a breakpoint at the suspect line, and print the local variables when it pauses.
