This skill equips Claude with specialized knowledge for Lean 4 theorem proving, offering a robust "build-first" workflow that integrates directly with Lake and Mathlib. It provides advanced tools for resolving type class synthesis errors, managing sorry markers, and performing automated proof repair using a multi-stage solver cascade. Whether working on program verification, pure mathematics, or measure theory, the skill ensures high-quality, axiom-free results by leveraging real-time feedback from the Lean compiler and LSP server to guide the proof process.
