Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install behavior-preserving-code-simplification

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 checks project conventions, limits the scope of changes and applies 47 rules to reduce complexity, duplication and dead code. You get clearer code whose outputs, errors and APIs stay identical.
