+- `lsp_workspace_symbols` - Search workspace symbols by query
+- `lsp_references` - Get LSP references with universal document identification
+- `lsp_resolve_code_action` - Resolve code actions with incomplete data
+- `lsp_apply_edit` - Apply workspace edits using Neovim's LSP utility functions
+
+**Universal LSP Tools** (enhanced existing tools):
+
+- `lsp_code_actions` - Now supports universal document identification
+  (buffer IDs, project paths, absolute paths)
+- `lsp_hover` - Enhanced with universal document identification
+- `lsp_document_symbols` - Get document symbols with universal document identification
+
+### Installation Improvements
