Generates minimal working examples (MWEs) from Lean 4 errors and panics to streamline bug reporting and debugging.
The lean-mwe skill automates the process of isolating Lean 4 and Mathlib4 bugs by transforming complex source files into self-contained minimal working examples. It provides a structured workflow for setting up message guards, executing the lake minimizer tool, and refining the output into a concise format suitable for GitHub issues or community support. By handling import inlining and automated code deletion, this skill ensures that reported issues are reproducible and easy for maintainers to diagnose without needing access to a user's entire project environment.
