This Skill covers the essential workflows for configuring, building, testing, and debugging Lean 4 projects using Lake, making Lean development faster and more reliable.
Build the full project with lake build, then run the executable with lake exe computational_paths to verify the install.

Build Lean 4 projects with Lake using `lake build` for a full build, `lake build ComputationalPaths` for specific packages, or `lake build ComputationalPaths.Path.HIT.Circle` for targeted modules. Lake reads configuration from lakefile.toml and enforces toolchain settings via lean-toolchain.
Execute your Lean 4 project with `lake exe computational_paths` to run the built executable. Use `lake clean` to remove artifacts between test iterations, and `lake update` to refresh dependencies before re-running tests.
Debug Lean 4 compilation issues by verifying your lean-toolchain file matches project requirements and lakefile.toml is properly configured. Use verbose output flags with lake build commands to expose explicit error guidance and identify missing dependencies or configuration mismatches.
Yes, Lake supports targeted module builds. Use `lake build ComputationalPaths.Path.HIT.Circle` to compile individual modules rather than running a full build, reducing compilation time during development and debugging.
Run `lake update` to refresh all dependencies defined in lakefile.toml. This fetches the latest versions and ensures your toolchain and project dependencies stay synchronized before building or testing.
Two files control Lean 4 projects in Lake: lean-toolchain enforces the Lean compiler version and settings, while lakefile.toml defines project metadata, dependencies, build targets, and executable configurations.
