Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install systematic-bug-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 reproduces the problem, narrows the case, forms falsifiable hypotheses and instruments the code to find the exact mechanism. If you only ask for a diagnosis, it does not apply a fix.
