# Refactoring Tools

> Multi-file changes in an instant

Firebender takes advantage of built-in LSP refactoring actions. This lets it edit typed languages like Kotlin/Java much faster and safer.

## Rename Symbol

Here, the AI made 56 edits across 18 files in a few seconds. This would take \~215x longer if AI had to make each change with search-replace.

Uses IntelliJ's rename refactoring. Updates getters/setters, test names, imports, and type annotations. Warns on naming conflicts.

## Delete Symbol

Remove unused code. Checks for usages first, blocks deletion if symbol is still referenced. Optional force mode for intentional breaking changes.

In this example, the AI deletes a 318-line function in \< 1 second.
