GitHub launches awesome-copilot community resource hub with hundreds of Copilot customizations

The repository gathers community-contributed custom agents, instructions, skills, hooks, workflows, and plugins, with a companion website offering full-text search and filtering across hundreds of resources. The site also features a Learning Hub with tutorials ranging from core concepts to agentic workflows, MCP servers, and the Copilot coding agent. The repo also provides an llms.txt machine-readable manifest so AI agents can fetch the structured list directly. Developers using GitHub Copilot CLI or VS Code can install plugins directly with copilot plugin install <plugin-name>@awesome-copilot; if an older CLI throws an error, just run copilot plugin marketplace add github/awesome-copilot first to register the marketplace. This means developers relying on Copilot for daily coding can quickly adopt battle-tested community configs and cut redundant debugging costs. Resources are contributed by third-party developers, and the repo warns users to review agents and their docs before installing. It follows the all-contributors spec, welcomes all kinds of contributions, and cites official materials such as the VS Code Copilot customization docs.
