// LLM-assisted tools for informal proofs, proof strategy discussion, and code simplification
Lean 4 theorem proving toolkit: search lemmas, verify proofs, repair/simplify code, and get LLM-assisted informal proofs
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

| description | LLM-assisted tools for informal proofs, proof strategy discussion, and code simplification |
LLM-assisted tools for theorem proving support. All scripts are in skills/cli/.
| Tool | Purpose | When to use |
|---|---|---|
| informal-prover | Generate and verify step-by-step math solutions in a loop | When you want an LLM to attempt a full solution with auto-verification |
| discussion-partner | Free-form discussion about proof strategies or Lean code | When you are stuck and want high-level strategic advice |
| code-golf | Shorten and simplify an existing Lean proof via Gemini | After a proof works, to get a more elegant version |
