Safe refactoring with workspace-wide rename_symbol performs cross-reference checks to identify all occurrences before applying changes. Use dry-run previews to validate the impact across multi-file projects before committing edits, preventing breaking changes from incomplete renames.
Impact analysis via fast_refs scans your workspace to locate all references to a symbol, showing exactly what would be affected by a rename or modification. Combined with dry-run previews, this lets you verify the scope and prevent unintended side effects.
Structural validation using get_symbols extracts and verifies your codebase's symbol structure before and after edits. This AST-aware approach detects collision risks and ensures consistency across multi-file projects, catching structural issues before they propagate.
Post-change verification runs available tests after edits complete, confirming that your refactoring preserves functionality. Combined with collision detection and reference analysis, this ensures safe modifications across your entire codebase.
Use workspace-wide refactoring when renaming symbols, restructuring code across multiple files, or making changes where missed references could cause bugs. The automated reference checking and dry-run validation make large-scale refactors safer and faster than manual editing.
