What problem does it solve? Building genuinely fillable Word forms requires OpenXML constructs—SDT content controls, legacy FormField checkboxes, MERGEFIELD placeholders, and document protection—that plain document generators do not produce, leaving users stuck with underscore-line pseudo-forms that capture no structured data. ## Core Features & Use Cases - Structured Fillable Fields: Adds SDT content controls (text, richtext, dropdown, combobox, date) and legacy FormField checkboxes via the OfficeCLI command line, with alias/tag metadata and lock settings. - Mail-Merge Templates: Inserts MERGEFIELD, REF, SEQ, and IF conditional fields for data-driven contract and letter templates. - Document Protection & Locking: Enforces protection=forms so only designated fields are editable, with per-field lock modes for multi-role forms like patient/physician intake. - Use Case: An HR team needs an onboarding intake form where new hires fill name, start date, and department dropdown while the rest of the document stays locked; this skill generates that .docx with real content controls and enforced protection. ## Quick Start Ask the AI to create a fillable employee onboarding form in Word with text fields for name, a date picker for start date, a department dropdown, an agreement checkbox, and document protection so only the fields are editable.
