Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install database-schema-design

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 breaks requirements into entities, sets the relationships and adds cross-cutting concerns (multi-tenancy, soft deletes, audit). It proposes migrations, TypeScript or Python types, RLS policies, seed data and a Mermaid diagram, using a full task-management SaaS example.
