GitHub Copilot CLI expands agent-style workflows in the terminal

GitHub detailed new and upcoming Copilot CLI capabilities aimed at letting developers hand off common terminal tasks—like repo setup, port triage, and issue lookup—to an agentic assistant.

GitHub shared today how GitHub Copilot CLI is evolving into an agentic assistant for terminal-first workflows.

  • The tool entered public preview in September 2025 and GitHub says it has shipped frequent updates since then.
  • The post (by Dylan Birtolo) is based on a GitHub Universe 2025 presentation demonstrating end-to-end terminal workflows.
  • Example flows include delegating repo setup (like cloning and dependency discovery) directly from a natural-language prompt inside the CLI.
  • Copilot CLI can help diagnose “port already in use” problems by identifying the process using a port (for example, 3000) and guiding termination.
  • GitHub also highlighted agent features such as selecting custom agents via an /agent command, searching repo issues through the bundled GitHub MCP server, and dispatching background work with /delegate that can result in a pull request.
