Install with the CLI

In a terminal, from the folder you want:

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

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 applies targeted changes: function extraction, renaming, breaking down giant methods, better typing and duplicate removal. Each step keeps external behaviour, and the agent says when it is better to leave code alone.
