GitHub Copilot CLI: Terminal Agent Built Into Your Development Workflow

GitHub Copilot CLI is the first terminal agent with structural platform advantage—its GitHub-native MCP integration enables direct issue context and automated PR workflows that Claude Code and Codex CLI cannot match. The model-agnostic /fleet feature runs parallel subagents across different models, letting teams compare and converge on optimal solutions. Included in all existing Copilot plans at no extra cost, it extends rather than replaces developers' current workflows.
