This repository contains reusable GitHub Copilot artifacts organized by type: prompts, agents, instructions, and skill. These are tools I am using to extract more value and performance from github copilot (and other agents using the sync-agents skills).
Inspired by github/awesome-copilot — a fantastic community-driven collection of Copilot prompts, instructions, and tools. If you find this repo useful, you'll love that one too. Highly recommend checking it out (and contributing!).
