Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install lean-formal-proof-workflow

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 first checks the Lean 4 installation, then structures the proof into phases: research, skeleton, counterexample search, implementation and audit. You get a compiled Lean proof, without having to master the whole syntax.
