What problem does it solve? Building genuinely fillable Word forms requires OpenXML constructs (SDT content controls, legacy FormFields, MERGEFIELD placeholders, document protection) that plain document generators do not produce, and OfficeCLI's add-time prop limitations silently discard complex attributes like dropdown items and date formats. ## Core Features & Use Cases - Structured form fields: Creates SDT content controls (text, richtext, dropdown, combobox, date), legacy FormField checkboxes, and MERGEFIELD mail-merge placeholders with alias/tag metadata. - Three build paths: Pure CLI for simple fields, raw-set XML injection for dropdown items and date formats, and Word-template workflows for signature pictures and grouped controls. - Protection and locking: Applies documentProtection modes and per-control locks (sdtLocked, contentLocked) for role-gated multi-party forms. - Use Case: Build an employee onboarding intake form with name and start-date fields, a department dropdown with real options, an agreement checkbox, and forms protection so only the fields are editable in Word. ## Quick Start Ask the AI to create a fillable Word intake form with a full-name text field, a start-date picker, a department dropdown, and an agreement checkbox, then lock the document so only those fields are editable.
