LLM-assisted tools for informal proofs, proof strategy discussion, and code simplification

Search tools for finding Lean theorems, lemmas, and definitions in Mathlib

Code transformation tools for repairing, simplifying, and extracting Lean proofs

Isolates failing proof steps by replacing them with `sorry` and extracting them into standalone lemmas to modularize and decouple complex Lean 4 proofs.

Verification tools for compiling, validating, and disproving Lean theorems
