Use when authoring a NEW rsc skill or editing an existing one — scoping it to one job, writing the description that decides whether it ever loads, splitting the body into references/, writing its evals, auditing it against the rubric. NOT building a product feature (that is `specify`) and NOT designing an agent loop (that is `building-agents`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# author-skill — write skills that trigger and teach This is the **meta skill**: it authors and edits the other skills in the rsc catalog. A skill is two things bolted together — a **description that fires at the right moment**, and a **body that makes the agent better once it fires**. Most skills fail on the first. Treat them as two separate engineering problems with two separate quality bars. Where the SDD chain (`specify` → `plan` → … → `ship`) builds *product*, `author-skill` builds *the tools that build product*. Use it whenever a skill is born or edited. **Not this skill — delegate:** a product feature specced or planned → `../specify/SKILL.md`, `../plan/SKILL.md`. An autonomous agent or tool-calling loop → `../building-agents/SKILL.md`. Generic project docs or a wiki article → the `../harness/SKILL.md` 02-DOCS engine. Bootstrapping a workspace or profiling the user → `../init/SKILL.md`. …

How to install
mdr add ericrisco/rsc-harness/author-skill@sha256:c501ceaadcec8117The line at the top of this page pins the label git:20261003.f0c84d6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
