Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install migrate-airflow-2-to-3

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The agent scans your DAG code for outdated imports, operators, hooks and API calls, then proposes replacements. It can run Ruff's automatic fixes and lists what remains. You get an inventory of changes and code ready for Airflow 3.
