Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install jvm-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 starts Java Flight Recorder recordings, uses jcmd for thread and heap dumps and analyses garbage collector behaviour. You get the commands to run and how to read the results.
