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.

Security

Grade A, and why

devexpress-office-file-api-word-processing 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 12d ago.

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.

DevExpress Word Processing Document API

The Word Processing Document API is a non-visual .NET library for creating, loading, editing, and exporting Word processing documents programmatically — without requiring Microsoft Office. It supports .docx, .doc, .rtf, .odt, .txt, .html, .mht, and WordML formats and can export to PDF, HTML, and image series. The primary entry point is RichEditDocumentServer, a server-side class suitable for console apps, ASP.NET Core, Blazor, MAUI, and background services.

When to Use This Skill

Use this skill when you need to:

  • Create Word documents (.docx, .rtf, .odt) programmatically without Microsoft Office
  • Load and modify existing .docx / .doc / .rtf files in .NET
  • Apply character and paragraph formatting, styles, or linked styles
  • Build tables, lists, hyperlinks, and bookmarks in code
  • Add headers, footers, footnotes, endnotes, or watermarks
  • Perform mail merge — generate personalized letters, invoices, or reports from a data source
  • Search and replace text, including regex-based search
  • Export Word documents to PDF, HTML, or a series of page images
  • Compare two documents and produce a revision-marked result
  • Accept or reject tracked changes programmatically
  • Merge or split Word documents
  • Work with fields (MERGEFIELD, TOC, HYPERLINK, PAGE, DATE, IF, etc.)
  • Protect documents with passwords or restrict editing permissions
