skill-author skillA

skill-author is agent-read markdown (skill) from laude-institute/headlong: Create new ShellLM skills. Use when the user asks to write, author, build, or scaffold a new skill, or when an agent needs to extend its own capabilities by creating a new SKILL.md file..

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 laude-institute/headlong/skill-author@git:20260820.6323e14
Exact content
mdr add laude-institute/headlong/skill-author@sha256:f54b6db8341cb10a

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.
