Authors or extends a skill in mc-agent-toolkit. Gates for forbidden buckets and name collisions, applies CONTRIBUTING's extend-or-split rules, then edits a peer skill or hands off to Anthropic's skill-creator and walks the registration checklist.
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
# toolkit-skill-author ## Pre-load ```bash !test -f CONTRIBUTING.md || (echo "CONTRIBUTING.md missing — run from repo root." && exit 1) ``` **Verify `skill-creator` is callable in this session.** Scan the available-skills list for a skill named `skill-creator` (bare or namespaced, e.g. `skill-creator:skill-creator`). If absent, abort with **exactly this message**: > `skill-creator` plugin is required. Run `/plugin install skill-creator@claude-plugins-official`, enable it, then restart this session and re-run `/toolkit-skill-author`. Do **not** fall back to manually scaffolding SKILL.md — the handoff is core to the workflow.

How to install
mdr add monte-carlo-data/mc-agent-toolkit/toolkit-skill-author@sha256:0b2e4430d1a97539The line at the top of this page pins the label git:20260618.50ca708, 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.
