WHY IT NEEDS A POLICY

Why build_docx needs a policy

This tool assembles research content into a formatted .docx document, which is a file creation/write operation. It produces a new output artifact but does not execute code, delete data, or involve financial transactions. The description is truncated, slightly lowering confidence, but the server description confirms it produces 'APA 7 formatted .docx output'.

From the tool's definition 'Assemble all sections, figures, tables, and references into' — implies creating/writing a .docx output file
