Use this skill when working on CPython's experimental JIT compiler - modifying Tools/jit/ build scripts, editing Python/jit.c runtime code, changing bytecode that affects JIT stencils, debugging JIT failures, or working with the copy-and-patch compilation pipeline. Covers LLVM toolchain setup, stencil generation, JIT configure flags, and the template.c to jit_stencils.h build flow.
