# Rename & refactor > Rename symbols across every file, move symbols and files without breaking imports, extract functions, and organize imports using Empryo's LSP-backed refactors. ## Rename a symbol everywhere Just ask: ``` > rename UserService to AccountService ``` The agent runs `refactor` (action: `rename_symbol`) - one LSP-backed call updates every file and verifies there are no dangling references. Works for functions, classes, types, interfaces, variables, enums. No need to tell it which file. ## Move a symbol to a different file ``` > move parseConfig from src/utils.ts to src/config/parser.ts ``` Moves the symbol, updates every import across the project, fixes re-exports. Full support for TypeScript, JavaScript, Python, Rust. ## Rename a file ``` > rename src/old-name.ts to src/utils/new-name.ts ``` Moves the file, updates every importer. ## Extract a function or variable ``` > extract lines 42-58 of handler.ts into a function called validateInput ``` Uses `refactor extract_function` - an LSP-backed code action. The extracted code becomes a new function with the right parameters and return type. ## Organize imports ``` > clean up imports in src/api.ts ``` Sorts, dedupes, removes unused imports via LSP. ## Tips - You don't need to say **which file** for rename. The agent finds it. - If multiple symbols share a name, the agent will ask you to pick. - Run `/lsp status` to confirm your LSP is attached before a big rename. - Changes are checkpoint-saved automatically. `Ctrl+B` undoes them all.
