Awesome Copilot

Copilot agent builder is a GitHub Copilot feature that scaffolds a custom agent definition from a one-line prompt. It generates agent markdown containing a description, front matter, success criteria, and methodology, which can then be edited for local use or further sharing and automation.

Copilot Workshops is an open-source collection of guided, hands-on lessons for exploring GitHub Copilot's agentic capabilities across the software development lifecycle. Its content covers the Copilot CLI, VS Code agent mode, the GitHub Copilot app, and the Copilot cloud agent, with Markdown lessons, images, and an Astro + Starlight site that publishes the material; the workshop's Tailspin Toys demo application is maintained in a separate repository. The repository is MIT-licensed.

The GitHub Copilot SDK is a multi-platform SDK from GitHub for embedding the agent runtime behind Copilot CLI in applications and services. It provides SDKs for Node.js/TypeScript, Python, Go, .NET, Java, and Rust, allowing applications to invoke Copilot agent workflows while the runtime handles planning, tool invocation, file edits, and related orchestration. Applications can also define custom agents, skills, and tools. Each SDK communicates with Copilot CLI running as a server over JSON-RPC. The SDK manages the CLI process lifecycle automatically and can connect to an externally run CLI server. The repository provides package-specific installation and API instructions; the CLI is bundled automatically for Node.js, Python, and .NET, while Go, Java, and Rust generally require a separately available CLI, with application-level bundling features available for Go and Rust. Standard use requires a GitHub Copilot subscription, and usage follows the Copilot CLI billing model, with prompts counted toward the applicable allowance. A BYOK mode supports API keys from supported providers without GitHub authentication.

GitHub Copilot coding agent is an autonomous coding agent on GitHub's platform. It can be delegated coding work from the command line or other interfaces, then take action on repositories in the background. GitHub describes the GitHub.com surface as supporting repository exploration, change planning, and delegation of coding tasks without leaving GitHub.com.

Awesome Agent Skills is an open-source curated collection of more than 1,000 agent skills from official development teams and the community. Each listing provides a description and source link; the collection includes skills from projects such as Anthropic, Google Labs, Vercel, Stripe, Cloudflare, and others. The skills are documented for use with multiple coding-agent environments, including Claude Code, Codex, Gemini CLI, Cursor, GitHub Copilot, OpenCode, and Windsurf.
