Create, edit, or inspect Berd skills stored as skill folders with SKILL.md files. Use when the user wants to build a new skill, update an existing skill, convert a workflow into a reusable skill, or decide whether instructions, scripts, references, or assets belong in a skill.
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 Builder Use this skill when creating, editing, or inspecting Berd skills. ## What a Skill Is A skill is a folder with a required `SKILL.md` file and optional supporting resources: ```text skill-name/ ├── SKILL.md ├── scripts/ ├── references/ └── assets/ ``` Do not create `README.md`, `CHANGELOG.md`, or extra documentation files inside a skill folder. Skill documentation belongs in `SKILL.md` or `references/`. ## Storage Decision Skills can be global or project-local: - Global: `~/.agents/skills/<skill-name>/SKILL.md` - Project-local: `<project>/.agents/skills/<skill-name>/SKILL.md` Default to global unless the user is clearly working in a project directory. If a project directory is active and the user has not specified scope, ask whether the skill should be saved for this project only or globally for all projects. Do not ask when intent is clear: - Project-local: "this repo", "this project", "only here", "project skill" - Global: "all projects", "global", "personal skill", "always available" When editing an existing skill, keep it in its current location unless the user explicitly asks to move it. ## Format …

How to install
mdr add block/berd/skill-builder@sha256:8fc80e9306fe4cacThe line at the top of this page pins the label git:20260812.9b88cac, 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.
