Rename

Rename a symbol (variable, function, class, file) across the entire codebase.

Steps

1. Accept the old name and new name from the argument.
2. Determine the symbol type:
   • Variable, function, or class name.
   • File or directory name.
   • Database column or table name.
   • CSS class or ID.
3. Find all references to the symbol:
   • Source code: imports, exports, usages, type references.
   • Tests: test descriptions, assertions, mocks.
   • Configuration: env vars, config files, CI pipelines.
   • Documentation: README, comments, API docs.
4. If renaming a file:
   • Update all import paths referencing the old filename.
   • Update any dynamic imports or require statements.
   • Update references in configuration files (tsconfig paths, webpack aliases).
5. Preview all changes before applying:
   • Show each file that will be modified with the specific line changes.
   • Highlight any ambiguous matches that might be false positives.
6. Apply changes across all files simultaneously.
7. Run the test suite and type checker to verify nothing broke.

Format

Rename: <old-name> -> <new-name>
Type: <function|variable|class|file>

Files affected: <N>
  - <file>:<line> - <context of change>

Verification:
  - Type check: <pass/fail>
  - Tests: <pass/fail>

Rules

• Show a preview of all changes and get confirmation before applying.
• Handle case sensitivity: distinguish myFunc, MyFunc, MY_FUNC.
• Do not rename symbols in node_modules, vendor, or other dependency directories.
• Preserve casing conventions (camelCase, PascalCase, snake_case, UPPER_CASE).
• Check for string literals that reference the symbol name (API routes, error messages).
• Update both the symbol and related names (e.g., renaming User should also update UserProps, UserSchema).
