What is the Aristotle Prover skill?

Aristotle Prover is a specialized capability for Claude Code that enables formal mathematical theorem proving by connecting to the Harmonic Aristotle API.

Does this skill require a subscription or API key?

Yes, you need the aristotlelib Python package and a valid ARISTOTLE_API_KEY environment variable to use the formal verification features.

Can it help me with existing Lean 4 files?

Yes, the skill can process Lean files with 'sorry' stubs and attempt to fill them with verified proofs using Aristotle's formal engine.

What happens if my mathematical claim is incorrect?

The skill features counterexample detection; if a statement is false, it will attempt to return a formal proof of negation or a specific counterexample.

Is this suitable for general software debugging?

This skill is specifically optimized for mathematical logic and algorithm verification. For general code debugging, standard Claude Code capabilities are recommended.

Translates natural language mathematical conjectures into Lean 4 and verifies them using Harmonic’s Aristotle formal theorem prover.

The Aristotle Prover skill bridges the gap between informal mathematical reasoning and rigorous formal verification within Claude Code. By leveraging the Harmonic Aristotle engine, it allows users to convert natural language math questions into structured Lean 4 code, fill in missing proof stubs, and prove the correctness of complex algorithms or mathematical properties. Whether you are verifying convergence guarantees, regret bounds, or searching for counterexamples to false claims, this skill provides a direct pipeline to a verified formal proof environment.
