What Is GitHub Copilot?
GitHub Copilot is an AI coding platform from GitHub that works across repositories editors the command line and agent based development workflows. It started as an intelligent code completion tool but now supports much broader software engineering tasks including planning codebase questions multi file edits debugging and autonomous agent sessions.
From Code Completion To Coding Agents
Copilot can suggest code while you type or work at a larger scope through chat and agent experiences. Developers can describe a feature or bug in natural language and let the agent inspect project context edit files run commands react to test failures and iterate on the implementation. Cloud based coding agents can also work on GitHub issues and return changes through pull requests for human review.
Model Choice And Developer Control
GitHub supports multiple AI models across Copilot experiences. The exact models available depend on the plan and surface being used. Developers can review generated changes control permissions customize project instructions and connect external tools through supported agent integrations such as MCP.
Who Is GitHub Copilot Best For?
- Developers who want AI assistance inside their existing editor
- Teams working heavily with GitHub repositories and pull requests
- Engineers using agents for refactoring debugging and feature work
- Students who want explanations and coding guidance while learning
- Organizations that need centrally managed AI development policies

How to use
How To Use GitHub Copilot
- Sign In To GitHub: Use a GitHub account and activate Copilot Free or another eligible Copilot plan.
- Choose Your Development Surface: Open Copilot on GitHub or install and enable it in a supported IDE. Copilot CLI can be used for terminal based workflows.
- Open Your Repository: Give Copilot access to the project you want to understand or modify so it can use relevant code context.
- Choose The Right Interaction: Use inline completion for small edits chat for questions Plan for implementation strategy or an agent for multi step work.
- Describe The Task Clearly: State the goal expected behavior constraints and relevant files or tests.
- Review The Plan And Permissions: Check what the agent intends to change and approve tool actions according to your preferred permission level.
- Let Copilot Implement And Test: The agent can edit files run commands inspect failures and iterate when the selected workflow permits it.
- Inspect The Final Diff: Review generated code run your own tests and security checks then keep revise or revert the changes before merging.
