homoglyph-obfuscation-counterexample skillA
homoglyph-obfuscation-counterexample is agent-read markdown (skill) from bruc3van/agent-skills-guard: Generated counterexample containing mixed-script lookalike account names.
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 bruc3van/agent-skills-guard/homoglyph-obfuscation-counterexample@git:20260608.9f59278mdr add bruc3van/agent-skills-guard/homoglyph-obfuscation-counterexample@sha256:54fb5c6f2672a41ePin 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.
