Create new skills, evaluate and iteratively improve them, and package them for distribution — without binding to any specific agent runtime. Use when the user wants to build a skill from scratch, draft and run evals to measure skill quality, compare candidate versions, tune a skill's description for better triggering, or package a finished skill. Triggering evaluation is done through a runtime-pluggable adapter interface (Claude Code, Codex, Cursor, or a manual fallback) so the same workflow…
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
# Skill Creator (runtime-agnostic) A skill for creating skills and iteratively improving them — **not tied to Claude Code or any single agent runtime**. It owns two layers of the meta-skill stack: - **L0 Generation** — turn an intent into a skill draft. - **L1 Evaluation** — measure skill quality with evals, compare candidates, iterate. The companion skill **skill-evolution** owns L2 (case-driven evolution) and L3 (accumulating what "a good skill" means). The two are independent and reference each other by document only; either can be used alone. ## High-level flow 1. Decide what the skill should do and roughly how. 2. Draft the skill (structure + description + references/templates). 3. Write a few test prompts (evals). 4. Run the skill against the evals via a **runner adapter** (or the manual fallback). 5. Review results with the user — qualitative + quantitative. 6. Rewrite based on feedback; repeat until satisfied. 7. Optionally tune the description for triggering accuracy. 8. Package. Your job is to figure out where the user is in this flow and help them progress. Be flexible — if the user wants to "just vibe", do that instead of running full evals. …

How to install
mdr add labs21-dev/agents-stack/skill-creator@sha256:e4c91f1e3f98f1b6The line at the top of this page pins the label git:20260912.9d47cf0, 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.
