What problem does it solve?

This Skill solves missing or incomplete code intelligence in GitHub Copilot CLI by installing and configuring the right Language Server Protocol (LSP) server so Copilot can provide accurate go-to-definition, find-references, hover, and type information.

Core Features & Use Cases

  • Language Server Installation: Selects and installs an appropriate LSP server for the chosen programming language, including OS-specific guidance.
  • Safe Configuration Merging: Adds the new LSP server entry to the correct Copilot CLI configuration location without clobbering existing servers.
  • Verification & Troubleshooting: Validates that the LSP binary is reachable on PATH, ensures JSON correctness, and provides post-setup checks inside Copilot CLI.
  • Use Case: For a mixed-language repo (e.g., TypeScript, Python, and Go), configure user-level or repo-level LSP settings so code intelligence works consistently across file types.

Quick Start

Ask Copilot CLI to enable LSP for TypeScript and Python using the repo-level configuration.

FAQPage Schema
How do I configure LSP servers for GitHub Copilot CLI code intelligence?ā–¼

To configure LSP servers for GitHub Copilot CLI code intelligence, you install the appropriate language server and merge its configuration entry into your user-level or repo-level JSON config file, ensuring the binary is on PATH before restarting Copilot CLI.

Why does go-to-definition or hover fail in Copilot CLI for my multi-language repository?ā–¼

Go-to-definition, hover, and reference lookups fail in Copilot CLI when LSP support is missing. Installing and configuring the specific language server for each programming language in your multi-language repository restores accurate code intelligence.

Can I add a new language server to Copilot CLI without overwriting existing lspServers settings?ā–¼

Yes, you can add a new language server without overwriting existing lspServers settings. The configuration process performs safe JSON config merging that preserves your currently installed servers while appending the new LSP entry to the correct targeting location.

How do I verify that my LSP setup is working correctly in Copilot CLI?ā–¼

To verify your LSP setup is working, validate that the LSP binary is reachable on PATH, ensure the JSON config is correct, and run post-setup LSP status checks inside Copilot CLI after restarting it to confirm go-to-definition and hover functionality.

Does Copilot CLI LSP configuration require OS-specific installation steps?ā–¼

Yes, Copilot CLI LSP configuration requires OS detection to provide OS-specific installation steps for the language server. This ensures the LSP binary is correctly installed and accessible on PATH across different operating systems before advising a Copilot CLI restart.

When should I use repo-level versus user-level configuration for Copilot CLI code intelligence?ā–¼

Use repo-level configuration for Copilot CLI code intelligence when onboarding multi-language repositories needing consistent LSP settings across file types, and user-level configuration when you want the language server available globally across all your development projects.
