When a vtk-mcp server is available, the client now calls is_dsl_prompt() before code generation; if the input is plain natural language it calls translate_prompt_to_dsl() to convert it to the structured VTK pipeline DSL before RAG retrieval and generation. VTKMCPClient.translate_prompt() accepts optional model, base_url, and api_key overrides so callers can direct the translation to a specific model or Ollama endpoint without changing server config.

Summary
VTKMCPClientgainstranslate_prompt(query, model?, base_url?, api_key?)method that calls the newtranslate_prompt_to_dslvtk-mcp toolclient.pynow callsis_dsl_prompt()before code generation; natural language input is translated to the VTK pipeline DSL before RAG retrieval and code generation begin. Prompts already in DSL format are passed through unchanged--dsl-translation/--no-dsl-translationCLI flag and UI checkbox to opt out of auto-translation--debugflag (CLI andvtk-prompt-ui) that dumps the full LLM conversation, including injected context and vtk-mcp tool calls/results, to stdoutWhy
The VTK pipeline DSL (structured
create / <filter> / define / add / renderspecification with snake_case setter names as parameters) hits the vtk-index BM25 index far more precisely than natural language, reduces the LLM's tool-calling rounds during generation, and leaves almost no hallucination space for class or method names. This change makes the quality improvement automatic for all vtk-prompt users with a vtk-mcp server, while keeping an escape hatch, a debugging aid, and clearer feedback on vtk-mcp connectivity.Dependencies
