Agent Skills

Agent Skills give AI coding assistants relevant context for specific development tasks. The teams-dev skill is the go-to agent skill for Teams bot development. It gives AI coding assistants (Claude Code, Cursor, GitHub Copilot, and others) relevant context to assist in developing Teams bots and use the Teams Developer CLI to manage your bot infrastructure. Instead of running CLI commands manually, you describe what you want and your AI assistant handles the rest.

Note

Alternative: Use llms.txt directly If you'd rather not install a skill, you can provide the same context by pointing your AI tool to the llms.txt URL:

https://microsoft.github.io/teams-sdk/llms_docs/llms.txt

Install the teams-dev skill

Add the marketplace (first time only):

/plugin marketplace add microsoft/teams-sdk

Install the skill:

/plugin install teams-sdk@teams-skills

After installing, restart GitHub Copilot for the skills to load.

What the skill covers

The teams-dev skill guides your AI assistant through:

Task What it does
Manage bot infrastructure Register your bot with Teams, manage credentials, and update configuration
Develop Teams bot Build bot applications from scratch or add Teams capabilities to existing servers
Set up SSO Enable Single Sign-On so users can authenticate seamlessly without login prompts
Troubleshoot Diagnose and resolve common bot setup and configuration issues

The skill does not cover hosting or deployment — it focuses on bot registration, development, and configuration.

Invoke the skill

Using natural language:

  • "I need a chatbot for my team's standup meetings"
  • "Help me build a Teams bot that can answer FAQs"
  • "My bot won't load in Teams, can you help?"
  • "Add the ability to get user profile information to my bot"

The skill loads automatically when your agent detects a relevant request.

Direct invocation:

/teams-dev

Example session

You: Help me create a Teams bot that echoes what I'm saying back to me

Agent: I'll create an echo bot for you.

       [checks Teams Developer CLI installation and authentication]
       [creates development tunnel: https://abc123.ngrok.io]
       [runs teams app create with endpoint]
       ✓ Bot registered, credentials saved to .env

       [runs teams project new typescript echo-bot -t echo]
       ✓ Bot code created in ./echo-bot

       [installs dependencies and starts bot server]
       ✓ Bot running at http://localhost:3978

       Your bot is ready! Install it in Teams:
