Copilot CLI adds /ask and plugins

GitHub’s Copilot command-line tool has added a new `/ask` command, expanded plugin distribution, and pushed remote session control onto the web and mobile. (github.com) (github.blog) The `/ask` addition appears in the Copilot CLI changelog for version 1.0.25, dated April 13, 2026, alongside a new `/env` command and guided installation for Model Context Protocol servers from a registry. GitHub’s documentation already describes the CLI as a tool that can record sessions locally and let users ask questions about those interactions. (github.com) (docs.github.com) Plugins are now a first-class distribution layer for the tool. GitHub says a plugin can bundle custom agents, skills, hooks, Model Context Protocol server configurations, and Language Server Protocol integrations into one installable package. (docs.github.com) GitHub has also formalized the marketplace model around those plugins. The company’s docs say Copilot CLI ships with two plugin marketplaces registered by default — `copilot-plugins` and `awesome-copilot` — and users can browse, install, or add more marketplaces from the terminal. (docs.github.com) That changes what the terminal tool is for. GitHub’s own description of Copilot CLI says it is powered by the same “agentic harness” as the company’s coding agent and is meant to work directly with repositories, issues, and pull requests from the command line. (github.com) (github.blog) The remote-control update, published April 13, 2026, moves those sessions beyond one machine. GitHub says `copilot --remote` can stream a running terminal session to GitHub on the web or in GitHub Mobile, where the same user can monitor progress, send follow-up commands, switch modes, and approve or deny permission requests. (github.blog) GitHub says remote sessions stay private to the user who started them, but business and enterprise customers need an administrator to enable remote control and CLI policies before the feature works. The company also tells users to run `/update` to get the latest version and to start remote mode inside a GitHub repository. (github.blog) (github.com) These updates land weeks after GitHub moved Copilot CLI to general availability on February 25, 2026, and days after version 1.0.24 shipped on April 10 with fixes tied to remote setup and session behavior. The release page shows version 1.0.24 as the latest tagged release, while the changelog on `main` already lists 1.0.25 changes dated April 13. (github.blog) (github.com 1) (github.com 2) Taken together, the new `/ask` flow, plugin marketplaces, and remote controls make Copilot CLI look less like a single local assistant and more like a GitHub-managed development surface that happens to live in a terminal.
