Scaffold a new skillhub skill, or repair one that drifted, across all four registration surfaces in one motion — folder, README table row, marketplace plugin, and trigger evals — then prove it with validate-skills.py. User-invoked.
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
# newskill — add a skill without drift `/newskill scaffold <name> "<description>" <category>` — create a new skill, registered `/newskill fix [<name>]` — complete a skill that exists in some surfaces but not others A skillhub skill lives in **four surfaces**, and it is only really "added" when all four agree: 1. **Folder** — `.claude/skills/<name>/SKILL.md` with valid frontmatter. 2. **README table row** — a row in the right category table (a prose mention does *not* count; the validator checks for a table row specifically). 3. **Marketplace** — `<name>` listed in one plugin's `skills[]` in `.claude-plugin/marketplace.json`. 4. **Trigger evals** — cases in `evals/triggers.json` (model-invoked skills only; user-invoked skills are exempt). **Drift** is these four disagreeing — the default failure of hand-adding a skill. The oracle for drift is `python3 scripts/validate-skills.py`: it already reports which surfaces are missing. This skill's whole job is to make the four agree and leave the validator green. ## The loop (both modes end here) Run `python3 scripts/validate-skills.py` → read each FAIL/WARN → fix that exact …

How to install
mdr add duthaho/skillhub/newskill@sha256:437a5dc47673579fThe line at the top of this page pins the label git:20260718.6f391f9, 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.
