Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install code-refactoring-method

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 spots code smells (long functions, duplication, long parameter lists, large classes) and applies refactoring techniques in small steps, with tests after each change. You get a refactoring plan and the matching changes.
