Language Server plugins give Claude live diagnostics after every save — type errors and unused imports get fixed before you even read the diff. Claude's code often hides type errors, unused imports, or missing return types that look fine at a glance. LSP plugins run a real language server alongside the agent: the moment a file is saved, the server flags issues so Claude can fix them in the same turn. Pick your language and install — make sure the language-server binary is also on your system. Implementation example: /plugin install typescript-lsp@claude-plugins-official /plugin install pyright-lsp@claude-plugins-official /plugin install rust-analyzer-lsp@claude-plugins-official /plugin install gopls-lsp@claude-plugins-official # Run /plugin and open the Discover tab for the full list.
