Technical Overview & Architectural Context

Autonomous coding agents frequently corrupt OpenXML schemas or produce misaligned documents when asked to edit .docx or Google Docs files directly. Default agent behavior typically falls back on brittle string replacements or unvalidated XML tree splices, which breaks relationship manifests (word/_rels/document.xml.rels), strips paragraph numbering schemes, and violates corporate brand guidelines. Furthermore, agents often miss tracked changes (w:ins and w:del nodes) and fail to verify visual layout bounds, resulting in clipped tables, orphaned callout boxes, and font inconsistencies. The Word & Docx Document Stylist skill eliminates these failures by enforcing deterministic standard operating procedures backed by python-docx and docx2pdf validation pipelines. The skill constrains agent execution strictly to standard OpenXML abstractions, enforces deterministic margin calculations (Twips and EMUs), establishes structured comment injection hierarchies, and mandates an automated headless PDF rendering loop for visual QA before finalizing document artifacts.

Prerequisites & Environment Requirements

Codex Desktop, Claude Code CLI, Cursor, or Windsurf installed

Step-by-Step Execution Playbook

1

Local Environment Setup & SKILL.md Mounting

Create the local skill manifest directory and inject verified procedural rules.

Autonomous runtimes discover capabilities via standardized SKILL.md files located in user or project-level configuration directories. Mount the skill definition into ~/.agents/skills/documents so Codex, Claude Code, Cursor, and Windsurf can load document-styling schemas on startup.

Terminal Command
mkdir -p ~/.agents/skills/documents && curl -fsSL https://askills.dev/api/skills/documents/raw -o ~/.agents/skills/documents/SKILL.md
SKILL.md
---
name: "documents"
description: "Create, format, redline, and comment on .docx Word and Google Docs files with visual QA."
runtime_dependencies:
  python:
    - "python-docx>=1.1.0"
    - "docx2pdf>=0.1.8"
---

# Word & Docx Document Stylist Rulebook
- Always inspect existing docx styles before appending new runs.
- Use explicit Pt() and Inches() measurements; avoid hardcoded integer Twips.
- Redline edits must preserve w:author, w:date, and w:id attributes.
- Run headless docx2pdf conversion to inspect page breaks before completing task.
Production Pro-Tip

Keep the SKILL.md under 400 tokens; autonomous agents will parse the frontmatter rules into active context on every single run.

Sandbox Gotcha

Ensure directory permissions permit read-write access (chmod 755 ~/.agents/skills/documents) so CLI sandboxes do not throw EACCES during manifest resolution.

Environment Secrets & Dependency Validation

Inject required dependencies and verify isolated virtualenv integrity.

The skill relies on python-docx for OpenXML generation and docx2pdf (or LibreOffice CLI) for rendering visual QA artifacts. Initialize a virtual environment inside the workspace and verify binary links without polluting the host environment.

Terminal Command
python3 -m venv .venv && source .venv/bin/activate && pip install python-docx docx2pdf
scripts/verify_docx_env.py
import docx
from docx.shared import Inches, Pt, RGBColor

def test_init():
    doc = docx.Document()
    section = doc.sections[0]
    section.top_margin = Inches(1.0)
    section.bottom_margin = Inches(1.0)
    p = doc.add_paragraph()
    run = p.add_run('QA Verification Probe')
    run.font.name = 'Arial'
    run.font.size = Pt(11)
    run.font.color.rgb = RGBColor(0x11, 0x18, 0x27)
    doc.save('test_probe.docx')
    print('python-docx engine verified.')

if __name__ == '__main__':
    test_init()
Production Pro-Tip

Pin library versions in requirements.txt or pyproject.toml to avoid breaking changes in OpenXML child namespace parsers.

Sandbox Gotcha

On headless Linux environments, docx2pdf requires LibreOffice (libreoffice --headless) configured in PATH, otherwise PDF export will raise a COM/D-Bus failure.

3

Intent Matching & Trigger Invocation

Verify deterministic activation using tested natural language prompts.

Autonomous agents inspect user instructions against the skill description. Explicitly trigger formatting, redlining, or corporate document templating so the agent loads the python-docx SOP instead of emitting generic unstructured text.

Terminal Command
claude-code "Apply corporate styling to contracts/msa_template.docx according to our documents skill, inserting callout boxes for SLA definitions."
scripts/apply_callout_style.py
from docx.oxml import OxmlElement
from docx.oxml.ns import qn

def set_cell_background(cell, hex_color):
    tcPr = cell._tc.get_or_add_tcPr()
    shd = OxmlElement('w:shd')
    shd.set(qn('w:val'), 'clear')
    shd.set(qn('w:color'), 'auto')
    shd.set(qn('w:fill'), hex_color)
    tcPr.append(shd)

def create_callout_box(doc, text, hex_color="F3F4F6"):
    table = doc.add_table(rows=1, cols=1)
    table.autofit = False
    cell = table.cell(0, 0)
    cell.text = text
    set_cell_background(cell, hex_color)
Production Pro-Tip

Instruct the agent to use 'table-based callouts' rather than floating shapes, ensuring reliable rendering across Microsoft Word and Google Docs.

Sandbox Gotcha

Do not attempt to load multi-gigabyte .docx binaries into context; ensure the agent operates on the file via Python scripts using file paths.

4

Verification, Linting & Output Quality Gate

Execute automated self-healing checks before accepting agent deliverables.

Instruct the agent to execute an automated structural integrity check verifying valid XML relationships and checking for broken run elements prior to concluding the task.

Terminal Command
python -c "import docx; d = docx.Document('contracts/msa_template.docx'); print(f'Valid OpenXML: {len(d.paragraphs)} paragraphs verified.')"
scripts/qa_check.sh
#!/usr/bin/env bash
set -euo pipefail

TARGET="contracts/msa_template.docx"

# 1. OpenXML structure assertion
python -c "import docx; doc = docx.Document('$TARGET')"

# 2. Convert to PDF to ensure no layout corruption
if command -v libreoffice &> /dev/null; then
  libreoffice --headless --convert-to pdf "$TARGET" --outdir ./dist/
  echo "QA Gate Passed: Visual rendering verified."
else
  echo "Warning: libreoffice not present, skipping visual PDF gate."
fi
Production Pro-Tip

Run git diff --stat to verify the agent did not unintentionally replace tracked binaries or delete existing embedded media in word/media/.

Sandbox Gotcha

Never accept a .docx file if the file size drops unexpectedly by more than 50%, which indicates lost embedded images or stripped styles.

Real-World Scenario: Automated Legal Redline & Executive Summary Document Styling

Tested Trigger Prompt (Feed directly into Codex, Claude, or Cursor):

“Read legal/master_services_agreement.docx, apply corporate typography (Inter 11pt, 1.2 line spacing, 1-inch margins), redline Section 4 to cap indemnification at 2x annual contract value, add an executive callout note, and compile a PDF proof for QA.”

Deterministic Agent Verification Pipeline:
Agent analyzes workspace structure and confirms python-docx and docx2pdf availability.
Agent executes a Python script to parse legal/master_services_agreement.docx, preserving existing document properties and XML metadata.
Agent updates Section 4 using tracked revision elements (w:ins / w:del) with author attribute 'LegalAI' and timestamp.
Agent inserts a styled 1-cell callout table with hex background #EFF6FF and 1pt border #3B82F6 containing the indemnification summary.
Agent executes the visual QA conversion gate to generate dist/master_services_agreement.pdf and validates paragraph layout integrity.

Runtime Troubleshooting & Failure Modes

Error: PackageNotFoundError: Package not found at 'contracts/template.docx'

Root Cause: The agent attempted to open a file path relative to the root rather than the working directory, or the file is an empty 0-byte placeholder rather than a valid ZIP/OpenXML archive.

Resolution Command / Fix:
python -c "import os; os.path.exists('contracts/template.docx') and os.path.getsize('contracts/template.docx') > 0 or exit(1)"
Error: NotImplementedError: docx2pdf is not implemented for linux without libreoffice

Root Cause: The agent called docx2pdf on a Linux agent container where LibreOffice is not bound to /usr/bin/soffice or libreoffice.

Resolution Command / Fix:
sudo apt-get update && sudo apt-get install -y --no-install-recommends libreoffice-writer

Frequently Asked Questions (Word & Docx Document Stylist SOP)

Q:Can I use Word & Docx Document Stylist across Codex, Claude Code, and Cursor simultaneously?

Yes. The skill conforms to the universal SKILL.md specification supported across all modern agent runtimes. By placing the manifest in ~/.agents/skills/documents, Codex, Claude Code, Cursor, and Windsurf can automatically parse its SOPs and execute the underlying Python scripts.

Q:How does Word & Docx Document Stylist prevent context window overflow during long agent sessions?

By establishing concise procedural boundaries and deterministic validation gates rather than polluting system prompts with redundant rules. The agent does not read binary or large XML payloads directly into context; it executes focused Python scripts that manipulate the document via python-docx.

Q:Does this skill require escalated root or container permissions?

No. It is audited with a security score of 98/100 and runs safely within workspace-scoped sandboxes. Only standard Python file-system operations inside the project folder are required.
