A simple greeting skill that says hello to the user.

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

This skill greets the user with a friendly message.

## Usage

Ask the agent to say hello, and it will respond with a warm greeting.

## Examples

- "Say hello" → "Hello! How can I help you today?"
- "Greet me" → "Hi there! What would you like to do?"

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add kalarislabs/skill-doctor/hello-world@sha256:a02bb8a8d917b9b1

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.
