crap-index-assess skillA

crap-index-assess is agent-read markdown (skill) from yarlson/yarstack: Assess method-level change risk with the Change Risk Anti-Patterns (CRAP) index and recommend focused testing or complexity reduction. Use when a repository configures CRAP measurement, cyclomatic complexity and automated test coverage data are available, or a user asks what CRAP means, how to calculate or interpret it, or how to reduce a CRAP score..

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 yarlson/yarstack/crap-index-assess@git:20260724.a1b6f43
Exact content
mdr add yarlson/yarstack/crap-index-assess@sha256:3c78cda32553d6c5

Pin 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.
