 5. **Review the diff output using AI** – attach the diff and ask it to analyze it.
    * If only intentional changes appear, proceed to merge / re-test.
    * If unexpected API, DOM, or style changes surface, iterate on the fix and repeat steps 1-4.

 **Purpose**: Creates static surface contracts for component templates and styles
 **AI Usage**: Generate contracts before refactoring to track breaking changes
 **Key Parameters**:
-- `directory`: Component directory
+- `saveLocation`: Path where to save the contract file (supports absolute and relative paths)
 - `templateFile`: Template file name (.html or .ts for inline)
 - `styleFile`: Style file name (.scss, .css, etc.)
 - `typescriptFile`: TypeScript component file (.ts)

 **Best Practice**: Create contracts before major refactoring for comparison
 
 #### `diff_component_contract`
 **Purpose**: Compares before/after contracts to identify breaking changes
 **AI Usage**: Validate that refactoring doesn't introduce breaking changes
 **Key Parameters**:
