Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install performance-root-cause-analysis

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 asks questions first, then sweeps resources (utilization, saturation, errors) and thread states before drilling down and confirming the cause. Each investigation ends in an evidence-based analysis or postmortem report. You get a supported diagnosis and verified fixes.
