Add ODT skill — OpenDocument text creation and template filling

What this adds

A new skills/odt/ skill enabling Claude to create and fill OpenDocument Format text files (.odt) using odf-kit, a Node.js library built specifically for this purpose.

Why

The current document skills cover docx, pdf, pptx, and xlsx — but not odt. ODT is:

• The ISO standard document format (ISO/IEC 26300)
• The native format for LibreOffice, the most widely used open-source office suite
• Required by many governments (EU, Italy, France, Brazil, India, and others mandate or prefer ODF)
• Supported by Google Docs, Microsoft Office, Collabora, OnlyOffice

Without this skill, Claude falls back to Python workarounds (odfpy) when users request .odt files — producing correct output but using an ad-hoc approach rather than a purpose-built tool.

What odf-kit provides

Two modes of document generation:

1. Programmatic creation — Builder API for headings, paragraphs, formatted text, tables (with cell merging, borders, backgrounds), bullet/numbered lists with nesting, images, hyperlinks, bookmarks, tab stops, page layout, headers/footers, page breaks. Fluent method chaining throughout.

2. Template filling — Load a .odt template created in LibreOffice with {placeholder} syntax, fill with JSON data. Supports loops, conditionals, dot notation for nested data, and automatic healing of XML fragments (LibreOffice splits placeholders across multiple XML spans — odf-kit reassembles them before replacement).

Library details:

• npm: odf-kit (v0.3.0)
• GitHub: GitHubNewbie0/odf-kit
• License: Apache 2.0
• Runtime dependencies: fflate only (zero transitive dependencies)
• Test suite: 222 passing tests
• Node.js: 22+ (ESM only)

Environment requirement

odf-kit would need to be added to the pre-installed global npm packages in Claude's environment, matching the pattern used by docx and pptxgenjs:

npm install -g odf-kit

SKILL.md structure

Follows the established pattern of the docx skill:

• YAML frontmatter with trigger description listing ODT/ODF/OpenDocument/LibreOffice keywords
• Quick reference table
• Programmatic creation section covering the full API with progressive examples (simple → builder callback)
• Template filling section with syntax reference, loops, conditionals, nesting
• Validation guidance using LibreOffice headless
• Critical rules section (async save, ESM only, required image options, etc.)
• Complete example showing a realistic multi-section report

Checklist

• SKILL.md with YAML frontmatter (name, description, license)
• Under 500 lines (474 lines)
• API examples verified against source
• Apache 2.0 license
• No bundled scripts needed (library installs via npm)

Hi @klazuka — I submitted this PR a while back adding an ODF/ODT skill. It fills the gap between the existing docx, pdf, pptx, and xlsx document skills — ODF is the ISO standard format required by 20+ governments. Would appreciate a look when you have a chance, or guidance on whether community skill PRs are being reviewed. Thank you very much, I appreciate!!!
