Install with the CLI

In a terminal, from the folder you want:

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

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 models tables and relationships, chooses indexes and partitions, writes zero-downtime migrations using expand-contract, and reviews an existing schema against known anti-patterns. For multi-tenant isolation, it plans the RLS rules. You get a schema and a migration plan.
