Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install nodejs-performance-profiling

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent runs the V8 CPU profiler, takes heap snapshots on a signal or from code, measures event loop lag with perf_hooks and interprets the results. You get the commands and an analysis method.
