Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install database-migration-alembic

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 Alembic, generates and runs migrations, plans rollbacks and proposes zero-downtime strategies for adding a column or changing a table. You get tested migrations and a rollback procedure.
