Core responsibilities:
- Produce complete, professional .docx deliverables ready for distribution
- Command the full vocabulary of document elements (covers, TOC, running headers/footers, pagination, charts, tables) and deploy them based on document purpose and user needs
- For new documents without a template, consult
guides/best-practices.md for sensible defaults
- When given a reference document or template, mirror its structure and formatting conventions
- Maintain consistent visual rhythm through spacing, alignment, and typographic scale
- Guarantee schema compliance and reliable rendering across Word, WPS, and LibreOffice
Workflow
| Step |
Action |
Why |
| 1 |
Choose the right stack: Document creation/modification -> C# + OpenXML SDK. Read-only analysis -> Python |
Tooling discipline |
| 2 |
Set working directory: Every docx_engine.py invocation MUST run from the user workspace (cwd), never from the skill installation path. Use absolute paths: python3 <skill-path>/docx_engine.py ... |
Build artifacts land in cwd/.docx_workspace/ and outputs in cwd/output/ |
| 3 |
Check environment: python3 <skill-path>/docx_engine.py doctor |
Surface missing dependencies and auto-setup |
| 4 |
Study implementation guides: development.md + troubleshooting.md + Folio.cs |
Absorb patterns before writing code |
| 5 |
Build: python3 <skill-path>/docx_engine.py render |
Compiles, generates, and validates in one pass |
| 6 |
Validate independently: python3 <skill-path>/docx_engine.py audit <file.docx> |
Runs schema + business-rule checks on any .docx |

Build Pipeline
Always invoke python3 <skill-path>/docx_engine.py render from the user's working directory.
Key point: Every docx_engine.py command must be run from cwd, not the skill directory. The .docx_workspace/ staging area and output/ directory are created under cwd.
Pipeline stages:
- Source compilation (
dotnet build)
- Document generation (
dotnet run)
- Element ordering normalization (ECMA-376 schema-driven)
- Schema validation (OpenXML SDK)
- Rule-based quality verification
Commands
# Environment diagnostics and auto-setup
python3 <skill-path>/docx_engine.py doctor
# Build and generate document
python3 <skill-path>/docx_engine.py render [output-name.docx]
# Validate existing document
python3 <skill-path>/docx_engine.py audit <document.docx>
# Quick content preview
python3 <skill-path>/docx_engine.py preview <document.docx>

Design Principles
Document elements and their typical applications:
| Element |
When to Use |
| Pagination |
Any multi-page document that benefits from navigation |
| Running headers/footers |
Documents requiring persistent identity (title, org, date) |
| Title page |
Formal deliverables: proposals, reports, theses, white papers |
| Table of Contents |
Long-form documents with three or more major sections |
| Decorative covers |
High-polish deliverables with branding or visual identity |
Consult guides/best-practices.md for sensible defaults when creating from scratch. If the user supplies a template, follow its conventions instead.
Visual Guidelines
- Favour understated colour palettes; avoid high-saturation defaults
- Provide ample whitespace (margins no less than 72 pt, paragraph spacing no less than 10 pt)
- Establish a clear typographic hierarchy (distinct heading sizes, consistent body text)
- Body text line spacing should be at least 1.5x
Flow Control
| Element |
Property |
Purpose |
| Primary heading |
PageBreakBefore + KeepNext |
Chapter separation |
| Secondary heading |
KeepNext |
Bind to following content |
| Pre-table text |
KeepNext |
Prevent orphaned introduction |
Multi-Column Layout
| Scenario |
Pattern |
Detail |
| Full-width header above multi-column body |
Section break with Continuous type |
See troubleshooting.md section 5.2 |
| Even content across columns |
Manual column breaks |
See troubleshooting.md section 5.3 |
| Single-page constraint (broadsheet) |
All sections Continuous, no page breaks |
See troubleshooting.md section 5.5 |
Note: Word columns are flow-based - text fills left to right. Without explicit column breaks, content may not reach all columns.
Pre-Delivery Checks
| Item |
Requirement |
| CJK quotation marks |
Use \u201c and \u201d escape sequences |
| Bookmark placement |
Must be direct paragraph children, not inside pPr |
| Drawing IDs |
Must be globally unique (use an incrementing counter) |
| Background images |
Generate via visuals/backdrops.py |
| Headers/footers |
If present, implement completely (no partial stubs) |
| Page numbers |
If included, verify correct field codes (PAGE / NUMPAGES) |
Content spot-check:
