A minimal example skill that greets users and explains how skills work. Use when user says "hello world skill", "test my skills setup", or "show me how skills work".
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
# Hello World Skill
A minimal working skill to verify your setup and understand the basic pattern.
## Instructions
When triggered, do the following:
1. Greet the user and confirm this skill was activated
2. Ask for their name if not already provided
3. Generate a personalized welcome message
4. Explain the three-level progressive disclosure system:
- Level 1: YAML frontmatter (always loaded, ~100 words)
- Level 2: SKILL.md body (loaded when triggered — you're reading it now)
- Level 3: Linked references (loaded as needed)
## Example
User says: "Test my skills setup"
Response:
- Confirm the hello-world skill activated successfully
- Greet the user
- Briefly explain what just happened (skill triggering via description match)
## Guidelines
- Keep responses concise and friendly
- This skill is for learning — point users to more complex skills as next steps
- Suggest they look at `skills/skills/skill-creator/` to build their own
The line at the top of this page pins the label v1.0.0, 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.
