Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install lean-proof-formalization

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 fixes the meaning of the statement, builds lemmas and their connections, checks the final theorem and its axioms, then writes a reproducible handoff. It is not meant for ordinary proof drafting. You get a verified, documented Lean proof.
