GitHub Copilot

GitHub Copilot is an AI coding agent that works across the software development lifecycle, from exploring codebases to planning projects, automating workflows, and reviewing changes. It is built into GitHub so users continue working in their existing development environment and workflow. The tool connects to issues and pull requests, automations, and repository history to provide context.

A Copilot session can start from an issue or pull request, with task, discussion, and repository context already connected. It can run tasks in parallel and continue work across surfaces, enabling automation of recurring work and review of local changes across surfaces.

Copilot supports multiple models and lets users choose or connect cloud or local models. It can be extended with repository instructions, skills, and connectors to bring in data and tools from other services and to discover MCP servers, skills, and plugins on GitHub.

Use cases

• Code completion and context-aware suggestions
