Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install evidence-driven-issue-diagnosis

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 first confirms the report is real and reproducible, then starts from the observed effect and climbs the call frames, processes and persistence boundaries. It keeps a hypothesis at each branch, tries to disprove it and prefers the simplest explanation. You get a reasoned diagnosis, with no fix proposed beforehand.
