+## Word manuscript editing defaults
+
+Use these defaults when the user asks QQsci to generate or revise a manuscript
+from local Word files, figures, and Supporting Information unless they explicitly
+ask for a separate output package:
+
+- Work directly on the user's target manuscript file when they ask to modify the
+  original file; do not create extra draft folders, backup files, or sidecar
+  documents unless requested or needed for safety.
+- Keep the user's existing filenames. If the project uses `Maunscript.docx` and
+  `SI.docx`, preserve those names instead of renaming them to normalized English
+  names.
+- Insert the main figures into the manuscript document itself when the task is to
+  produce a complete draft; place each figure next to its full AFM-style caption
+  and keep the figure order synchronized with the revised story.
+- Set inserted manuscript figures to a uniform width of 15 cm while preserving
+  aspect ratio, unless the user specifies another size.
+- Format manuscript text paragraphs with a two-character first-line indent and
+  justified alignment. Keep image-only paragraphs centered.
+- Do not leave temporary extraction files, intermediate Markdown files, renamed
+  copies, or generated backup folders in the project after the final manuscript
+  has been written back, unless the user asks to keep them.
+- Treat Supporting Information as a separate source/companion document unless the
+  user asks to rewrite it; do not rename or regenerate SI by default.
