Summary

Completed

You can now choose, author, package, and reuse skills for agents powered by the GitHub Copilot harness so agent behavior can be shared across agents, teams, and solutions.

What you learned

• Position skills in the GitHub Copilot component model: Skills add a portable behavior layer. They're the right component when a repeatable behavior needs to run consistently across more than one agent.
• Add skills to your agent: A skill's description decides when the orchestrator activates it, and its instructions decide how the agent behaves once it does. Review, test, and refine both, whether you adopt a pre-built skill or write one from scratch.
• Compose and package a skill for reuse: A skill's package format and its tool references shape how easily other agents can adopt it. Ship a SKILL.md file when the behavior lives in the instructions, and ship a ZIP when the skill needs supporting files.
• Reference authored skills and plan reuse: Reuse across agents runs on a download-and-upload cycle. A shared library with a named owner keeps the skills you promote to organization scope maintainable.
