Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| vtk_get_class_infoB | Get complete information about a VTK class including module path, description, and methods |
| vtk_get_class_methodsA | List all methods (with signatures) for a VTK class and optionally verify a specific method |
| vtk_search_classesC | Search for VTK classes by name or keyword |
| vtk_get_class_moduleA | Return the vtkmodules.* import path for a given VTK class |
| vtk_get_module_classesC | List all VTK classes in a specific module |
| vtk_validate_importC | Validate if a VTK import statement is correct and suggest corrections |
| vtk_get_method_infoB | Get documentation for a specific method of a VTK class |
| vtk_get_method_docA | Get just the docstring for a specific method of a VTK class |
| vtk_get_method_signatureA | Return only the canonical signature for a specific method of a VTK class (minimal payload) |
| vtk_get_class_docB | Get the class documentation string for a VTK class |
| vtk_get_class_synopsisA | Get a brief synopsis/summary of what a VTK class does |
| vtk_get_class_action_phraseB | Get the action phrase describing what a VTK class does (e.g., 'data reading', 'mesh filtering') |
| vtk_get_class_roleA | Get the pipeline role of a VTK class. Returns one of: input, filter, properties, renderer, scene, infrastructure, output, utility, color |
| vtk_get_class_visibilityA | Get the visibility score of a VTK class (0.0-1.0). Higher scores indicate classes more likely to be used directly. |
| vtk_get_class_input_datatypeA | Get the input data type for a VTK class (e.g., 'vtkPolyData', 'vtkImageData') |
| vtk_get_class_output_datatypeA | Get the output data type for a VTK class (e.g., 'vtkPolyData', 'vtkImageData') |
| vtk_get_class_semantic_methodsA | Get non-boilerplate callable methods for a VTK class. Excludes dunder methods, private methods, and VTK infrastructure methods. |
| vtk_is_a_classA | Check if a given name is a valid VTK class. Returns true if it exists in the VTK API, false otherwise. |
