What mathematical domains does it support?

It is highly effective for domains requiring formal rigor, such as convergence guarantees, optimization properties, regret bounds, and estimator consistency.

What is the Aristotle Prover skill for Claude Code?

It is a specialized extension that allows Claude Code to interface with Harmonic's Aristotle formal theorem prover to verify mathematical claims and generate Lean 4 code.

Do I need a separate API key to use this skill?

Yes, you must have the aristotlelib Python package installed and a valid ARISTOTLE_API_KEY set in your environment variables.

Can it help me fix incomplete Lean 4 files?

Absolutely. One of its primary uses is identifying 'sorry' stubs in Lean files and calling Aristotle to find formal proofs to fill them.

How does it handle false mathematical statements?

If a statement is false, the skill is designed to return a counterexample or a formal proof of negation rather than just failing.

Security & Testing

Translates mathematical statements into formally verified Lean 4 proofs or counterexamples using Harmonic's Aristotle API.

The Aristotle Prover skill bridges the gap between natural language mathematical reasoning and rigorous formal verification. By integrating Claude Code with Harmonic's Aristotle prover, it allows users to formalize conjectures, fill proof stubs in existing Lean 4 files, and verify algorithm correctness with high assurance. Whether you are proving convergence guarantees, checking regret bounds, or looking for counterexamples to mathematical claims, this skill provides an automated pipeline for formal mathematical discovery and verification.
