Agent request
Review the Skillstore skill "writer" from https://skillstore.io/skills/sickn33-writer.md and its manifest at https://skillstore.io/api/skills/sickn33-writer/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "writer". Create a quarterly report in ODT with a title, summary, results table, and conclusion.

Expected outcome:

A structured Writer document with styled headings, an accessible table, metadata, and a saved ODT source file.

Using "writer". Convert all ODT files in the reports folder to PDF and record failures.

Expected outcome:

  • A batch conversion plan with explicit input and output folders.
  • A result log listing successful files, failed files, and validation checks.

Using "writer". Generate personalized letters from a Writer template and spreadsheet data.

Expected outcome:

A mail merge workflow that maps fields, creates one document per recipient, and validates missing values before export.

Security Audit

Medium Risk
v6 • 9/7/2026 Open versioned report

All 33 static findings are false positives caused by constrained command examples, Markdown fences, temporary-directory use, documentation links, or misclassified LibreOffice commands. Semantic review found unsafe process termination, an unauthenticated local UNO listener, and unescaped template substitution.

Confirmed security concerns (3)

Medium
SKILL.md:175
Broad Process Termination Can Cause Data Loss
The troubleshooting guidance runs killall soffice.bin, which can terminate unrelated LibreOffice sessions and discard unsaved work.
The command explicitly targets every process with this executable name rather than the specific headless service.
Medium
SKILL.md:176
Unauthenticated Local UNO Service
The troubleshooting command opens a localhost UNO socket without access controls, potentially allowing other local processes to control LibreOffice.
The listener configuration is explicit, but the actual exposure depends on host isolation and local user trust.
Medium
SKILL.md:123-127
Unescaped XML Template Substitution
Template values are inserted directly into content.xml, so XML metacharacters can corrupt documents or inject unintended ODF markup.
The sample uses direct string replacement and does not escape values or construct XML text nodes.

What You Can Build

Generate Standard Documents

Create repeatable ODT templates for reports, letters, forms, and recurring business documents.

Convert Document Archives

Plan batch conversions between ODT, DOCX, PDF, and other supported formats.

Build Writer Automation

Design Python and UNO workflows that create, edit, and export Writer documents.

Try These Prompts

Create a Simple ODT 
Create an ODT document titled [title] with these sections: [sections]. Use accessible headings and consistent styles.
Plan a Format Conversion 
Convert [input file] from [source format] to [target format]. Preserve styles, list prerequisites, and verify the output.
Design a Batch Workflow 
Design a safe batch workflow for converting [folder and pattern] to [format]. Include output handling, logs, failure recovery, and validation.
Build a Template Pipeline 
Create a secure Writer template pipeline using [data source]. Escape inserted values, preserve ODT structure, generate [formats], and test accessibility.

Best Practices

  • Keep editable ODT sources and reusable templates under version control.
  • Validate layout, accessibility, fonts, and content after every format conversion.
  • Use structured XML or ODF APIs, isolated temporary directories, and explicit error handling.

Avoid

  • Do not insert unescaped user values directly into ODT XML.
  • Do not terminate every LibreOffice process when only one headless instance needs attention.
  • Do not assume conversion success without checking exit status and opening the output.

Frequently Asked Questions

Which document formats does this skill cover?
It covers ODT, DOCX, DOC, PDF, PDF/A, HTML, RTF, TXT, and EPUB, with direction varying by format.
Does it install LibreOffice automatically?
No. LibreOffice, Python, UNO bindings, and optional ODF libraries must be available in the working environment.
Can it process many documents?
Yes. It provides batch conversion patterns, but you must add validation, logging, and failure handling.
Can it create mail merge documents?
Yes. The guidance covers mail merge concepts with CSV, spreadsheet, or database data sources.
Will converted documents preserve formatting exactly?
Not always. Fonts, advanced layout features, filters, and LibreOffice versions can affect conversion fidelity.
Is the template replacement example safe for untrusted data?
No. Use an XML or ODF API that escapes inserted values before processing untrusted data.
