Lean developers often grapple with diagnosing Lean errors, locating relevant lemmas in mathlib, and coordinating cross-file proof tasks. This Skill provides an LSP-driven assistant that surfaces diagnostics, searches mathlib, and guides interactive formalization while preserving the user's code.
Start a guided Lean 4 session with /lean4:prove to begin interactive proof assistance.

This proof assistant searches mathlib by applying LSP-driven guidance to inspect Lean 4 proof goals and surface targeted lemmas, helping you locate relevant theorems for your current proof state.
This assistant fixes Lean 4 errors by parsing LSP diagnostics from your lake build, identifying proof blockers, and generating repair guidance while safely preserving your existing code.
The best way to analyze sorry placeholders in Lean 4 files is using a dedicated sorry analyzer script that identifies incomplete proofs and provides targeted guidance for formalizing the remaining goals.
Yes, you can use LSP to navigate cross-file references and check mathlib axioms in Lean 4, coordinating proof tasks with standard mathlib axioms to verify formalization correctness.
No, this proof assistant preserves your original Lean 4 code during automated repair, applying bounded proof cycles that orchestrate plan, work, checkpoint, review, and replan phases for safety.
Lean 4 proof searches get stuck without bounded cycles; this assistant enforces bounded proof cycles per goal, applying safe tactics using standard mathlib axioms to prevent infinite loops.
