Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install llm-prompt-optimization-regression

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 rewrites the prompt with structured instructions, then tests it against a task-specific evaluation and regression checks. You get a revised prompt and the criteria that justify it.
