GitHub Copilot CLI

The CLI extension lets developers invoke the Copilot AI assistant from any terminal session, enabling question‑answering, code generation, debugging, and GitHub interactions without leaving the command line. It supports Linux, macOS, and Windows (including PowerShell and WSL), and works with all Copilot subscription plans, subject to organizational policy settings when provided by a company.

Two interfaces are offered: an interactive mode that opens a conversational session where users can iteratively request tasks, give feedback, and switch between a direct ask/execute flow and a plan mode that first clarifies requirements and outlines a structured implementation. A programmatic mode allows a single prompt to be supplied via the command line, completing the task and exiting, with options to approve file modifications automatically.

The tool is designed for developers who prefer terminal‑based workflows and need quick AI assistance for coding tasks, pull‑request creation, and other GitHub‑related operations, while providing controls for context management and security.
