# LSP Setup for GitHub Copilot CLI **UTILITY SKILL** — installs and configures Language Server Protocol servers for Copilot CLI. USE FOR: "setup LSP", "install language server", "configure LSP for Java", "add TypeScript LSP", "enable code intelligence", "I need go-to-definition", "find references not working", "need better code understanding" DO NOT USE FOR: general coding tasks, IDE/editor LSP configuration, non-Copilot-CLI setups ## Workflow 1. **Ask the language** — use `ask_user` to ask which programming language(s) the user wants LSP support for 2. **Detect the OS** — run `uname -s` (or check for Windows via `$env:OS` / `%OS%`) to determine macOS, Linux, or Windows 3. **Look up the LSP server** — read `references/lsp-servers.md` for known servers, install commands, and config snippets 4. **Ask scope** — use `ask_user` to ask whether the config should be user-level (`~/.copilot/lsp-config.json`) or repo-level (`lsp.json` at the repo root or `.github/lsp.json`) 5. **Install the server** — run the appropriate install command for the detected OS 6. **Write the config** — merge the new server entry into the chosen config file (`~/.copilot/lsp-config.json` for user-level; `lsp.json` or `.github/lsp.json` for repo-level). If a repo-level config already exists, keep using that location; otherwise ask the user which repo-level location they prefer. Create the file if missing and preserve existing entries. 7. **Verify** — confirm the LSP binary is on `$PATH` and the config file...
