Node Inspect Debugger
This skill provides comprehensive guidance for debugging Node.js applications, addressing complex scenarios such as hidden locals, async hangs, flaky tests, child processes, startup races, memory growth, and CPU hot paths. It emphasizes starting with the built-in `node inspect` for interactive debugging, offering commands for stepping, breakpoints, and scope inspection within a REPL.
For more advanced use cases, the skill details how to leverage the Chrome DevTools Protocol (CDP) for programmatic control, enabling scripted breakpoints, automated state capture, and the generation of heap and CPU profiles. It includes practical quick-start examples, OpenClaw-specific tips, and a minimal CDP driver script, making it an invaluable resource for developers seeking to master Node.js debugging and performance analysis.
What It Does
This skill provides comprehensive guidance and commands for debugging Node.js applications. It covers interactive debugging with `node inspect`, advanced programmatic control via the Chrome DevTools Protocol (CDP), and methods for capturing heap and CPU profiles.
When To Use
Debugging complex Node.js issues (hidden locals, async hangs, flaky tests)
Analyzing memory growth or CPU hot paths in Node.js applications
Debugging child processes or startup races
Automating debugging tasks with scripted breakpoints or state capture
When needing deep inspector access beyond basic logging
Profiling application performance (CPU and Heap snapshots)
Inputs
Node.js application code, process IDs (PIDs), debugger commands, CDP scripts.
Outputs
Debugging insights, call stack information, variable states, heap snapshots, CPU profiles, process control (pause/resume).
