Automated summary

This skill generates simple greeting messages like 'Hello, [name]!' with an optional timestamp.

Strengths

  • Quickly and simply responds to greeting requests.
  • Handles empty, special, or very long names without error.
  • Includes an optional timestamp for temporal context.

Limitations

  • Only suitable for explicit greeting requests.
  • Cannot perform calculations, data processing, or code execution.
  • The handling of multiple names is basic (no aggregation).
When to use it

Use this skill when the user explicitly requests a greeting or to say hello to someone.

When not to use it

Do not use this skill for tasks requiring calculations, data processing, or any form of code execution.

Security analysis

Hello World Skill

This skill ONLY generates simple greeting messages. It is NOT suitable for calculations, data processing, or any code execution tasks.

When to Use This Skill

ONLY use this skill when:

  • The user explicitly asks to "say hello" or "greet" someone
  • The user wants a simple greeting message
  • Testing basic greeting functionality

DO NOT use this skill for:

  • Mathematical calculations (use calculator-skill instead)
  • Data processing or analysis
  • Code execution
  • Any task requiring computation

How It Works

This skill generates a simple greeting message in the format "Hello, [name]!" where [name] can be:

  • A name provided by the user
  • "World" as the default if no name is specified

Instructions

  1. Check if the user has provided a name to greet
  2. If no name is provided, use "World" as the default
  3. Generate the greeting message: "Hello, [name]!"
  4. Optionally include a timestamp

IMPORTANT: This skill should NOT invoke any tools for calculations or code execution. It only returns a simple text greeting.

Examples

Example 1: Default Greeting

User request: "Say hello"

Output:

Hello, World!
Generated at: 2024-12-25 10:30:00 UTC

Example 2: Personalized Greeting

User request: "Say hello to Alice"

Output:

Hello, Alice!
Generated at: 2024-12-25 10:30:00 UTC

Example 3: Multiple Names

User request: "Greet Bob and Charlie"

Output:

Hello, Bob!
Hello, Charlie!
Generated at: 2024-12-25 10:30:00 UTC

What This Skill Does NOT Do

  • ❌ Mathematical calculations
  • ❌ Data processing
  • ❌ Code execution
  • ❌ File operations
  • ❌ Web requests

If a user request involves any of the above, use a different skill (e.g., calculator-skill for calculations).

Edge Cases

  • Empty name: Treat as if no name was provided, use "World"
  • Special characters in name: Include them in the greeting as-is
  • Very long name: Accept and use the full name provided

Output Format

The greeting should be clear and friendly. Include:

  1. The greeting message
  2. A timestamp (optional but recommended)

Keep the output simple and human-readable.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/hello-world-skill-mma3js51/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/hello-world-skill-mma3js51' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/hello-world-skill-mma3js51/download' --output '.skill-downloads/hello-world-skill-mma3js51/SKILL.md.part' && mv '.skill-downloads/hello-world-skill-mma3js51/SKILL.md.part' '.skill-downloads/hello-world-skill-mma3js51/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/hello-world-skill-mma3js51'

openskills read 'hello-world-skill-mma3js51'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/hello-world-skill-mma3js51/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
