Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install sqlite-raw-queries-grdb

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 sets up DatabaseQueue or DatabasePool, writes typed SQL queries with complex joins and window functions, sets up ValueObservation for a reactive interface and handles migrations. It also says when to prefer SQLiteData.
