github/awesome-copilot

Awesome GitHub Copilot is a community-built collection of ready-made customizations for GitHub Copilot. It gathers agents, instructions, skills, hooks, workflows, and plugins — all contributed by developers — so you can find and install them in one place instead of hunting around.

What's inside (from the README):

Resource	What it is
Agents	Specialized Copilot agents that integrate with MCP servers.
Instructions	Coding standards that Copilot applies automatically based on file pattern.
Skills	Self-contained folders with instructions plus bundled assets.
Plugins	Curated bundles of agents and skills for specific workflows.
Cookbook	Copy-paste-ready recipes for working with Copilot APIs.

How to use it

Most users already have the Awesome Copilot marketplace registered in Copilot CLI or VS Code. You install a plugin directly:

copilot plugin install <plugin-name>@awesome-copilot

If you're on an older Copilot CLI version (or a custom setup) and get an “unknown marketplace” error, register it once first:

copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot

Companion website — awesome-copilot.github.com

• Full-text search and filtering across hundreds of resources.
• A Learning Hub with curated articles, walkthroughs, and reference material covering agents, skills, instructions, hooks, agentic workflows, MCP servers, and the Copilot coding agent.
• A machine-readable llms.txt with structured listings if you want to use this collection in an AI agent.

Contributing & safety

• Contributions follow guidelines in CONTRIBUTING.md, with AI-agent guidance in AGENTS.md, plus security and code-of-conduct policies.
• The README explicitly states that customizations come from third-party developers — you're advised to inspect any agent and its documentation before installing.

Who built it — The project lists dozens of contributors (about 70 named in the README), making clear it's a community effort rather than a single-vendor project.
