legacy-code-expert skillA
legacy-code-expert is agent-read markdown (skill) from jikig-ai/soleur: Use this agent when you need to safely modify legacy code that lacks tests. It applies Michael Feathers' dependency-breaking techniques from "Working Effectively with Legacy Code" to identify seams, plan characterization tests, and recommend safe transformation paths..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add jikig-ai/soleur/legacy-code-expert@git:20260409.f449cb6mdr add jikig-ai/soleur/legacy-code-expert@sha256:eeab8de9fce989ccPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
