Memento-Skills docx

Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of \"Word doc\", \"word document\", \".docx\", or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a \"report\", \"memo\", \"letter\", \"template\", or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.

DOCX creation, editing, and analysis

Overview

A .docx file is a ZIP archive containing XML files.

Quick Reference

TaskApproach
Read/analyze content
pandoc
or unpack for raw XML
Create new documentUse
docx-js
- see Creating New Documents below
Edit existing documentUnpack → edit XML → repack - see Editing Existing Documents below

Converting .doc to .docx

Legacy

.doc
files must be converted before editing:

python scripts/office/soffice.py --headless --convert-to docx document.doc

Reading Content

# Text extraction with tracked changes
pandoc --track-changes=all document.docx -o output.md

# Raw XML access
python scripts/office/unpack.py document.docx unpacked/

Converting to Images

python scripts/office/soffice.py --headless --convert-to pdf document.docx
pdftoppm -jpeg -r 150 document.pdf page

Accepting Tracked Changes

To produce a clean document with all tracked changes accepted (requires LibreOffice):

python scripts/accept_changes.py input.docx output.docx

Creating New Documents

Use

python-docx
to create .docx files (auto-installed, no extra setup needed).

Basic Document

from docx import Document
from docx.shared import Pt, Inches, Cm, RGBColor
from docx.enum.text import WD_ALIGN_PARAGRAPH

doc = Document()

# Set default font
style = doc.styles['Normal']
font = style.font
font.name = 'Arial'
font.size = Pt(11)

# Add content
doc.add_heading('Document Title', level=0)
doc.add_paragraph('This is a paragraph of text.')
doc.add_heading('Section 1', level=1)
doc.add_paragraph('Section content here.')

doc.save('output.docx')

Paragraphs & Text Formatting

from docx.shared import Pt, RGBColor

# Bold, italic, underline
p = doc.add_paragraph()
run = p.add_run('Bold text')
run.bold = True
run = p.add_run(' and ')
run = p.add_run('italic text')
run.italic = True

# Font color and size
run = p.add_run('Colored text')
run.font.color.rgb = RGBColor(0xFF, 0x00, 0x00)  # Red
run.font.size = Pt(14)

# Alignment
p.alignment = WD_ALIGN_PARAGRAPH.CENTER

Lists

# Bullet list
doc.add_paragraph('First item', style='List Bullet')
doc.add_paragraph('Second item', style='List Bullet')

# Numbered list
doc.add_paragraph('Step one', style='List Number')
doc.add_paragraph('Step two', style='List Number')

Tables

from docx.shared import Inches, Pt, RGBColor
from docx.oxml.ns import qn

table = doc.add_table(rows=3, cols=3, style='Table Grid')

# Header row
header = table.rows[0]
for i, text in enumerate(['Name', 'Role', 'Email']):
    cell = header.cells[i]
    cell.text = text
    # Bold header
    for paragraph in cell.paragraphs:
        for run in paragraph.runs:
            run.bold = True

# Data rows
data = [['Alice', 'Engineer', 'alice@example.com'],
        ['Bob', 'Designer', 'bob@example.com']]
for i, row_data in enumerate(data):
    for j, text in enumerate(row_data):
        table.rows[i+1].cells[j].text = text

# Set column widths
for row in table.rows:
    row.cells[0].width = Inches(2)
    row.cells[1].width = Inches(2)
    row.cells[2].width = Inches(3)

Images

doc.add_picture('image.png', width=Inches(4))

# Centered image
paragraph = doc.paragraphs[-1]
paragraph.alignment = WD_ALIGN_PARAGRAPH.CENTER

Headers & Footers

from docx.shared import Pt

section = doc.sections[0]

# Header
header = section.header
header_para = header.paragraphs[0]
header_para.text = 'Company Name'
header_para.alignment = WD_ALIGN_PARAGRAPH.RIGHT

# Footer with page numbers
footer = section.footer
footer_para = footer.paragraphs[0]
footer_para.alignment = WD_ALIGN_PARAGRAPH.CENTER
# Add page number field
run = footer_para.add_run()
fldChar = OxmlElement('w:fldChar')
fldChar.set(qn('w:fldCharType'), 'begin')
run._r.append(fldChar)
run2 = footer_para.add_run()
instrText = OxmlElement('w:instrText')
instrText.text = ' PAGE '
run2._r.append(instrText)
run3 = footer_para.add_run()
fldChar2 = OxmlElement('w:fldChar')
fldChar2.set(qn('w:fldCharType'), 'end')
run3._r.append(fldChar2)

Page Setup

from docx.shared import Inches, Cm
from docx.enum.section import WD_ORIENT

section = doc.sections[0]

# US Letter size
section.page_width = Inches(8.5)
section.page_height = Inches(11)

# Margins
section.top_margin = Inches(1)
section.bottom_margin = Inches(1)
section.left_margin = Inches(1)
section.right_margin = Inches(1)

# Landscape
section.orientation = WD_ORIENT.LANDSCAPE
section.page_width, section.page_height = section.page_height, section.page_width

Advanced: Creating with docx-js (requires Node.js)

For advanced features like Table of Contents with auto-generation, complex numbering, or features not supported by python-docx, use docx-js:

npm install -g docx  # One-time setup
const { Document, Packer, Paragraph, TextRun, HeadingLevel, TableOfContents } = require('docx');

const doc = new Document({
  sections: [{
    properties: {
      page: {
        size: { width: 12240, height: 15840 },  // US Letter in DXA
        margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 }
      }
    },
    children: [
      new TableOfContents("Table of Contents", { hyperlink: true, headingStyleRange: "1-3" }),
      new Paragraph({ heading: HeadingLevel.HEADING_1, children: [new TextRun("Title")] }),
    ]
  }]
});

Validation

After creating the file, validate it. If validation fails, unpack, fix the XML, and repack.

python scripts/office/validate.py doc.docx

Editing Existing Documents

Follow all 3 steps in order.

Step 1: Unpack

python scripts/office/unpack.py document.docx unpacked/

Extracts XML, pretty-prints, merges adjacent runs, and converts smart quotes to XML entities (

“
etc.) so they survive editing. Use
--merge-runs false
to skip run merging.

Step 2: Edit XML

Edit files in

unpacked/word/
. See XML Reference below for patterns.

Use "Claude" as the author for tracked changes and comments, unless the user explicitly requests use of a different name.

Use the Edit tool directly for string replacement. Do not write Python scripts. Scripts introduce unnecessary complexity. The Edit tool shows exactly what is being replaced.

CRITICAL: Use smart quotes for new content. When adding text with apostrophes or quotes, use XML entities to produce smart quotes:

<!-- Use these entities for professional typography -->
<w:t>Here&#x2019;s a quote: &#x201C;Hello&#x201D;</w:t>
EntityCharacter
&#x2018;
‘ (left single)
&#x2019;
’ (right single / apostrophe)
&#x201C;
“ (left double)
&#x201D;
” (right double)

Adding comments: Use

comment.py
to handle boilerplate across multiple XML files (text must be pre-escaped XML):

python scripts/comment.py unpacked/ 0 "Comment text with &amp; and &#x2019;"
python scripts/comment.py unpacked/ 1 "Reply text" --parent 0  # reply to comment 0
python scripts/comment.py unpacked/ 0 "Text" --author "Custom Author"  # custom author name

Then add markers to document.xml (see Comments in XML Reference).

Step 3: Pack

python scripts/office/pack.py unpacked/ output.docx --original document.docx

Validates with auto-repair, condenses XML, and creates DOCX. Use

--validate false
to skip.

Auto-repair will fix:

  • durableId
    >= 0x7FFFFFFF (regenerates valid ID)
  • Missing
    xml:space="preserve"
    on
    <w:t>
    with whitespace

Auto-repair won't fix:

  • Malformed XML, invalid element nesting, missing relationships, schema violations

Common Pitfalls

  • Replace entire
    <w:r>
    elements
    : When adding tracked changes, replace the whole
    <w:r>...</w:r>
    block with
    <w:del>...<w:ins>...
    as siblings. Don't inject tracked change tags inside a run.
  • Preserve
    <w:rPr>
    formatting
    : Copy the original run's
    <w:rPr>
    block into your tracked change runs to maintain bold, font size, etc.

XML Reference

Schema Compliance

  • Element order in
    <w:pPr>
    :
    <w:pStyle>
    ,
    <w:numPr>
    ,
    <w:spacing>
    ,
    <w:ind>
    ,
    <w:jc>
    ,
    <w:rPr>
    last
  • Whitespace: Add
    xml:space="preserve"
    to
    <w:t>
    with leading/trailing spaces
  • RSIDs: Must be 8-digit hex (e.g.,
    00AB1234
    )

Tracked Changes

Insertion:

<w:ins w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z">
  <w:r><w:t>inserted text</w:t></w:r>
</w:ins>

Deletion:

<w:del w:id="2" w:author="Claude" w:date="2025-01-01T00:00:00Z">
  <w:r><w:delText>deleted text</w:delText></w:r>
</w:del>

Inside

<w:del>
: Use
<w:delText>
instead of
<w:t>
, and
<w:delInstrText>
instead of
<w:instrText>
.

Minimal edits - only mark what changes:

<!-- Change "30 days" to "60 days" -->
<w:r><w:t>The term is </w:t></w:r>
<w:del w:id="1" w:author="Claude" w:date="...">
  <w:r><w:delText>30</w:delText></w:r>
</w:del>
<w:ins w:id="2" w:author="Claude" w:date="...">
  <w:r><w:t>60</w:t></w:r>
</w:ins>
<w:r><w:t> days.</w:t></w:r>

Deleting entire paragraphs/list items - when removing ALL content from a paragraph, also mark the paragraph mark as deleted so it merges with the next paragraph. Add

<w:del/>
inside
<w:pPr><w:rPr>
:

<w:p>
  <w:pPr>
    <w:numPr>...</w:numPr>  <!-- list numbering if present -->
    <w:rPr>
      <w:del w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z"/>
    </w:rPr>
  </w:pPr>
  <w:del w:id="2" w:author="Claude" w:date="2025-01-01T00:00:00Z">
    <w:r><w:delText>Entire paragraph content being deleted...</w:delText></w:r>
  </w:del>
</w:p>

Without the

<w:del/>
in
<w:pPr><w:rPr>
, accepting changes leaves an empty paragraph/list item.

Rejecting another author's insertion - nest deletion inside their insertion:

<w:ins w:author="Jane" w:id="5">
  <w:del w:author="Claude" w:id="10">
    <w:r><w:delText>their inserted text</w:delText></w:r>
  </w:del>
</w:ins>

Restoring another author's deletion - add insertion after (don't modify their deletion):

<w:del w:author="Jane" w:id="5">
  <w:r><w:delText>deleted text</w:delText></w:r>
</w:del>
<w:ins w:author="Claude" w:id="10">
  <w:r><w:t>deleted text</w:t></w:r>
</w:ins>

Comments

After running

comment.py
(see Step 2), add markers to document.xml. For replies, use
--parent
flag and nest markers inside the parent's.

CRITICAL:

<w:commentRangeStart>
and
<w:commentRangeEnd>
are siblings of
<w:r>
, never inside
<w:r>
.

<!-- Comment markers are direct children of w:p, never inside w:r -->
<w:commentRangeStart w:id="0"/>
<w:del w:id="1" w:author="Claude" w:date="2025-01-01T00:00:00Z">
  <w:r><w:delText>deleted</w:delText></w:r>
</w:del>
<w:r><w:t> more text</w:t></w:r>
<w:commentRangeEnd w:id="0"/>
<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="0"/></w:r>

<!-- Comment 0 with reply 1 nested inside -->
<w:commentRangeStart w:id="0"/>
  <w:commentRangeStart w:id="1"/>
  <w:r><w:t>text</w:t></w:r>
  <w:commentRangeEnd w:id="1"/>
<w:commentRangeEnd w:id="0"/>
<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="0"/></w:r>
<w:r><w:rPr><w:rStyle w:val="CommentReference"/></w:rPr><w:commentReference w:id="1"/></w:r>

Images

  1. Add image file to
    word/media/
  2. Add relationship to
    word/_rels/document.xml.rels
    :
<Relationship Id="rId5" Type=".../image" Target="media/image1.png"/>

    <wp:extent cx="914400" cy="914400"/>  <!-- EMUs: 914400 = 1 inch -->
    <a:graphic>
      <a:graphicData uri=".../picture">
        <pic:pic>
          <pic:blipFill><a:blip r:embed="rId5"/></pic:blipFill>
