Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install neon-migration-specialist-subagent

First time: connect the CLI with

npx --yes palatekit@latest login

This subagent creates a test Neon database branch with a four-hour lifetime, runs the migrations there, validates the result and deletes the branch. It writes the migration files for a pull request, without applying them to the main branch. The main agent hands it a schema change.
