Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sql-queries-schema

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 writes SQL queries: filters, joins, aggregations, window functions, CTEs and subqueries, along with data changes and schemas. You get readable queries and a SQL migration template.
