skill-installer skillA

skill-installer is agent-read markdown (skill) from bruc3van/agent-skills-guard: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos)..

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 bruc3van/agent-skills-guard/skill-installer@git:20260609.08d2b92
Exact content
mdr add bruc3van/agent-skills-guard/skill-installer@sha256:0e78d250c15b431f

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.
