skill-tester skillA

skill-tester is agent-read markdown (skill) from ivuorinen/skills: Runs TDD pressure scenarios against a skill before and after it is written, proving the skill actually changes agent behaviour instead of merely reading well. Use when verifying a new or edited skill has real effect, establishing a RED baseline before authoring, or confirming a GREEN result after..

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

Latest version
mdr add ivuorinen/skills/skill-tester@git:20260907.99db6c5
Exact content
mdr add ivuorinen/skills/skill-tester@sha256:20ac724c43096e45

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.
