TL;DR · WeSearch summary

GitHub has launched Copilot CLI, a standalone terminal-based coding agent that competes with tools like Claude Code and OpenAI's Codex CLI. It integrates natively with GitHub repositories, enabling developers to plan, execute, and delegate code changes directly from the terminal. The tool supports multiple AI models, parallel subagent execution, and works within existing GitHub workflows and security policies.

Key facts

▪Copilot CLI is a terminal-native coding agent that operates outside of editors like VS Code.
▪It is included in all GitHub Copilot plans and supports model switching between Anthropic, Google, and OpenAI.
▪The /fleet feature allows parallel execution of subagents across different models for the same task.
▪Copilot CLI offers native access to GitHub issues, pull requests, and branch protections through its MCP integration.
▪It enables users to go from planning code with /plan to opening pull requests with /delegate in a single workflow.

Copilot CLI is a terminal-native coding agent that lives outside VS Code, competes head-on with Anthropic and OpenAI's standalone tools, and leans hard into one advantage neither rival can match: native GitHub integration.
