skill-authoring skillA
skill-authoring is agent-read markdown (skill) from nyldn/claude-octopus: Principles for writing skills that behave the same way every run — use when adding, editing, or reviewing a skill in this plugin.
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 nyldn/claude-octopus/skill-authoring@git:20260813.14437aemdr add nyldn/claude-octopus/skill-authoring@sha256:0fcbd89bf48e5ed8Pin 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.
