GitHub's official blog publishes a beginner-oriented tutorial on GitHub Copilot CLI, focusing on the slash commands that let users direct the terminal AI agent. The guide targets developers new to AI-assisted command-line workflows, explaining how typed slash directives shape Copilot's behavior in the shell. It serves as an on-ramp for those unfamiliar with Copilot's CLI surface beyond the standard web or IDE experience.
GitHub’s post shows how to install and configure language servers for GitHub Copilot CLI using the LSP Setup skill. The workflow selects a language, detects the OS, installs the right server, merges configuration, and verifies the setup. With LSP enabled, Copilot CLI can resolve types, jump to definitions, find references, and read hover docs with less reliance on grep or dependency scraping.
