A .NET development skill for adding AI text processing to Word documents, PDF files, and PowerPoint presentations through the DevExpress Office File API. It covers proofreading, translation, summaries, and questions about document content using language models.

In plain words
What is it for?
Use it to build .NET features that proofread, translate, summarize, or answer questions about office files and PDFs.
Why use it?
It helps developers connect document-processing code to supported cloud or local AI providers without guessing the relevant API patterns. The developer supplies the model access, because no DevExpress-hosted model is included.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    This pattern attempts to override system instructions or ignore safety constraints. Without LLM analysis, manual review is recommended.
    Fix: Remove or rewrite any text that instructs the agent to ignore prompts, override safety rules, or trust unverified content. Ensure skill content cannot be injected to alter agent behavior.

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-ai-powered-extensions 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 AI-Powered Extensions for Office File API

The DevExpress AI-Powered Extensions integrate language models into the Office File API through the Microsoft.Extensions.AI (IChatClient) abstraction. Extensions support proofreading, translation, summarization, and contextual Q&A (Ask AI) for Word Processing documents, PDF files, and PowerPoint presentations. Both cloud providers (Azure OpenAI, OpenAI, Google Gemini) and local models (Ollama, ONNX Runtime, AI Foundry Local) are supported. The API follows a BYOK ("bring your own key") model — no DevExpress-hosted LLM is included.

When to Use This Skill

Use this skill when you need to:

  • Proofread a Word document (.docx) or PowerPoint presentation with AI (grammar, spelling, style)
  • Translate a Word document, PDF file, or PowerPoint presentation to another language
  • Translate a specific paragraph, range, slide, or page region rather than the whole document
  • Summarize the content of a Word document, PDF file, or presentation
  • Ask contextual questions about document content using RAG (Retrieval-Augmented Generation)
  • Register an AI provider (Azure OpenAI, OpenAI, Ollama, Gemini, ONNX, AI Foundry Local) with the DevExpress container
  • Use the AIDocProcessingService or IAIDocProcessingService in a console app or ASP.NET Core / Blazor application
  • Preserve formatting while performing AI-powered document transformations
  • Process documents in a headless / server-side .NET environment without a UI control
