Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install n8n-credentials-and-secrets

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 picks the right authentication method for each service, binds existing credentials by ID and flags any secret typed in clear in a text field or in code. You get a setup that keeps secrets out of the workflow and stays maintainable.
