Writer

LibreOffice Writer

Overview

LibreOffice Writer skill for creating, editing, converting, and automating document workflows using the native ODT (OpenDocument Text) format.

When to Use This Skill

Use this skill when:

• Creating new documents in ODT format
• Converting documents between formats (ODT <-> DOCX, PDF, HTML, RTF, TXT)
• Automating document generation workflows
• Performing batch document operations
• Creating templates and standardized document formats

Core Capabilities

1. Document Creation

• Create new ODT documents from scratch
• Generate documents from templates
• Create mail merge documents
• Build forms with fillable fields

2. Format Conversion

• ODT to other formats: DOCX, PDF, HTML, RTF, TXT, EPUB
• Other formats to ODT: DOCX, DOC, RTF, HTML, TXT
• Batch conversion of multiple documents

3. Document Automation

• Template-based document generation
• Mail merge with data sources (CSV, spreadsheet, database)
• Batch document processing
• Automated report generation

4. Content Manipulation

• Text extraction and insertion
• Style management and application
• Table creation and manipulation
• Header/footer management

5. Integration

• Command-line automation via soffice
• Python scripting with UNO
• Integration with workflow automation tools

Workflows

Creating a New Document

Method 1: Command-Line

soffice --writer template.odt

Method 2: Python with UNO

import uno

def create_document():
    local_ctx = uno.getComponentContext()
    resolver = local_ctx.ServiceManager.createInstanceWithContext(
        "com.sun.star.bridge.UnoUrlResolver", local_ctx
    )
    ctx = resolver.resolve(
        "uno:socket,host=localhost,port=8100;urp;StarOffice.ComponentContext"
    )
    smgr = ctx.ServiceManager
    doc = smgr.createInstanceWithContext("com.sun.star.text.TextDocument", ctx)
    text = doc.Text
    cursor = text.createTextCursor()
    text.insertString(cursor, "Hello from LibreOffice Writer!", 0)
    doc.storeToURL("file:///path/to/document.odt", ())
    doc.close(True)

Method 3: Using odfpy

from odf.opendocument import OpenDocumentText
from odf.text import P, H

doc = OpenDocumentText()
h1 = H(outlinelevel='1', text='Document Title')
doc.text.appendChild(h1)
doc.save("document.odt")

Converting Documents

# ODT to DOCX
soffice --headless --convert-to docx document.odt

# ODT to PDF
soffice --headless --convert-to pdf document.odt

# DOCX to ODT
soffice --headless --convert-to odt document.docx

# Batch convert
for file in *.odt; do
    soffice --headless --convert-to pdf "$file"
done

Template-Based Generation

import subprocess
import tempfile
from pathlib import Path

def generate_from_template(template_path, variables, output_path):
    with tempfile.TemporaryDirectory() as tmpdir:
        subprocess.run(['unzip', '-q', template_path, '-d', tmpdir])
        content_file = Path(tmpdir) / 'content.xml'
        content = content_file.read_text()
        for key, value in variables.items():
            content = content.replace(f'${{{key}}}', str(value))
        content_file.write_text(content)
        subprocess.run(['zip', '-rq', output_path, '.'], cwd=tmpdir)
    return output_path

Format Conversion Reference

Supported Input Formats

• ODT (native), DOCX, DOC, RTF, HTML, TXT, EPUB

Supported Output Formats

• ODT, DOCX, PDF, PDF/A, HTML, RTF, TXT, EPUB

Command-Line Reference

soffice --headless
soffice --headless --convert-to <format> <file>
soffice --writer    # Writer
soffice --calc      # Calc
soffice --impress   # Impress
soffice --draw      # Draw

Python Libraries

pip install odfpy     # ODF manipulation
pip install ezodf     # Easier ODF handling

Best Practices

1. Use styles for consistency
2. Create templates for recurring documents
3. Ensure accessibility (heading hierarchy, alt text)
4. Fill document metadata
5. Store ODT source files in version control
6. Test conversions thoroughly
7. Embed fonts for PDF distribution
8. Handle conversion failures gracefully
9. Log automation operations
10. Clean temporary files

Troubleshooting

Cannot open socket

killall soffice.bin
soffice --headless --accept="socket,host=localhost,port=8100;urp;"

Conversion Quality Issues

soffice --headless --convert-to pdf:writer_pdf_Export document.odt

AGI Framework Integration

Memory-First Protocol

Retrieve prior documentation structure and content to maintain consistency. Cache generated docs to avoid regenerating unchanged sections.

# Check for prior documentation context before starting
python3 execution/memory_manager.py auto --query "documentation patterns and prior content for Writer"

Storing Results

After completing work, store documentation decisions for future sessions:

python3 execution/memory_manager.py store \
  --content "Documentation: API reference generated from OpenAPI spec, deployment guide updated with new env vars" \
  --type technical --project <project> \
  --tags writer documentation

Multi-Agent Collaboration

Share documentation changes with all agents so they reference the latest guides and APIs.

python3 execution/cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Documentation updated — API reference, deployment guide, and CHANGELOG all current" \
  --project <project>

Agent Team: Documentation

This skill pairs with documentation_team — dispatched automatically after any code change to keep docs in sync.
