Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install predicate-quantifier-analysis

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 identifies universal and existential quantifiers, converts the formula to prenex form and then applies Skolemization. It checks instantiations and models with Z3. You get a formal, step-by-step analysis of the formula.
