Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install root-cause-five-whys

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 builds a chain of causes backed by evidence, from the observed fault down to the root cause, then proposes a countermeasure that would have blocked the incident. Each link is verifiable.
