🌍 hello-world Plugin

The hello-world plugin is a complete demo that illustrates the four core extension points of GitHub Copilot CLI plugins.

Components

🤖 Greeter Agent (agents/greeter.agent.md)

A custom AI agent that greets the user by name and introduces the plugin's capabilities.

Usage in an interactive session:

/agent greeter

Then talk to it — it will ask your name and greet you personally.

💡 Hello Skill (skills/hello/)

A skill that responds to "hello" greetings with a personalized, formatted message. It demonstrates using a prompt (SKILL.md), a script (scripts/greet.sh), and a template (skills/hello/templates/greeting.md) together.

Trigger examples:

hello
hi there
hello, my name is Alice

🔔 Session-End Hook (hooks.json + scripts/session-end.sh)

A hook that fires at the end of every session and always prints:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  What else can I do for you?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

  Session ended (reason: complete).
  Feel free to start a new session anytime!

This demonstrates how hooks can enforce consistent behavior across all sessions.

🔌 Context7 MCP Server (.mcp.json)

Connects to Context7 — an MCP server that provides up-to-date library documentation fetched directly from source.

Example usage:

What is the latest Next.js App Router API?   (uses Context7 for fresh docs)
