What is libreoffice-writer?

A toolkit for creating and editing LibreOffice Writer documents, which are word-processing files such as .odt documents. It supports structured text, tables, images, formatting, exports, and page snapshots through LibreOffice's automation interface.

Use it to create, read, modify, format, export, and inspect Writer documents, including documents with tables, lists, and images.

It provides repeatable document edits without relying on manual editing in the Writer interface. Session-based operations help target specific text and document elements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00050	$0.02264
Opus 5	$0.00025	$0.01132
Sonnet 5	$0.00010	$0.00453
Haiku 4.5	$0.00005	$0.00226

Security

Grade A, and why

libreoffice-writer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

The scan reads SKILL.md. This mod also ships 13 executable files (scripts/colors.py, scripts/constants.py, scripts/exceptions.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 296 lines — stays where its author put it; the contents beside it link to each section on GitHub.

LibreOffice Writer

Use the bundled writer modules for UNO-backed Writer document work. All paths must be absolute. Bundled modules live under scripts/ in this skill directory, so set PYTHONPATH=<skill_base_dir>/scripts. If setup or runtime issues appear, check references/troubleshooting.md.

API Surface

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
