test-preserving-refactor skillA
test-preserving-refactor is agent-read markdown (skill) from yeaight7/agent-powerups: Use when code needs restructuring and observable behavior must stay unchanged, with existing tests kept green at every step..
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 yeaight7/agent-powerups/test-preserving-refactor@git:20260606.d9d0aabmdr add yeaight7/agent-powerups/test-preserving-refactor@sha256:b1a2f6d4b2c1e7abPin 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.
