GitHub is adding language-server support to Copilot CLI, giving the command-line assistant access to the same kind of code intelligence developers expect inside modern IDEs.
That matters because terminal agents often struggle when they lack project structure, symbol information, or precise diagnostics. Language servers can provide context about definitions, references, types, and errors without forcing the model to infer everything from raw files.
The update points toward a more practical version of AI coding: less generic chat, more tool-aware assistance grounded in the actual codebase.
