Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Bub's capabilities with specialized knowledge, workflows, or tool integrations.
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 This skill provides guidance for creating effective skills. ## About Skills Skills are modular, self-contained folders that extend Bub's capabilities by providing specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific domains or tasks—they transform Bub from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess. ### Skill Location Policy When creating a skill, place it in one of these two roots: 1. Project-local: `$workspace/.agents/skills/<skill-name>` 2. Global: `~/.agents/skills/<skill-name>` (shared across workspaces) Prefer project-local by default. Use global only when the user explicitly wants the skill available across multiple workspaces. ### What Skills Provide 1. Specialized workflows - Multi-step procedures for specific domains 2. Tool integrations - Instructions for working with specific file formats or APIs 3. Domain expertise - Company-specific knowledge, schemas, business logic 4. Bundled resources - Scripts, references, and assets for complex and repetitive tasks ## Core Principles ### Concise is Key …

How to install
mdr add bubbuild/bub/skill-creator@sha256:b8456a091cb2eb40The line at the top of this page pins the label git:20260428.eddc5eb, 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.
