What is Hello World Greeting Skill?
The Hello World Greeting skill is a specialized utility for the Openclaw Skills ecosystem, serving as both a functional greeting tool and a technical demonstration. It allows developers to configure personalized greetings by reading the HELLO_USERNAME environment variable, ensuring that the AI agent provides a consistent and strictly formatted response without additional modification.
This skill is essential for developers who want to verify that their Openclaw Skills environment is correctly configured. It highlights how metadata can enforce strict output constraints on AI agents, making it a reliable building block for more complex automation workflows.
Hello World Greeting Skill Use Cases
- Testing environment variable configuration within the Openclaw Skills framework.
- Demonstrating skill configuration UI and primary environment variable settings to new users.
- Implementing a simple, personalized greeting mechanism for AI agents to improve user experience.
- Validating that the skill loading and execution pipeline is functioning as expected in a new environment.
How Hello World Greeting Skill Works
- The user triggers the skill using natural language phrases like "Say hello" or "Greet me".
- The skill logic accesses the local environment to retrieve the HELLO_USERNAME variable.
- The system checks the current system time to determine the appropriate time-based salutation.
- It generates a two-line response: "Hello, {HELLO_USERNAME}!" followed by "Good morning/afternoon/evening!".
- The AI agent captures this raw output and presents it to the user exactly as generated, adhering to strict formatting rules defined in the Openclaw Skills metadata.
Hello World Greeting Skill Setup
To set up this skill within your Openclaw Skills environment, follow these steps:
- Open your skill configuration interface.
- Locate the
hello-worldskill. - Configure the required environment variable:
# Example of setting the variable in a shell environment
export HELLO_USERNAME="YourName"
- Alternatively, in the Openclaw UI, add
HELLO_USERNAMEto the environment variables section with your desired value. - Save the settings and restart your agent to apply changes.
Hello World Greeting Skill Data Schema & Taxonomy
The skill utilizes a simple but effective data schema to manage user identity and metadata:
| Attribute | Type | Description |
