Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install kiss-yagni-simple-code

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

When designing or refactoring, the agent looks for the most direct solution, drops unnecessary abstractions and unrequested features, and favors expected behavior. You get code that is easier to read, debug and test.
