Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install safe-django-migration-workflow

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 follows PostHog's migration procedure: it checks the risks, picks non-blocking changes and splits schema changes into several phases. It also covers deleting models, columns and migration files. You get a migration reviewed against these rules.
