O que é processamento-de-documentos-nutrient?

Esta skill integra-se com a API comercial Nutrient DWS Processor para automatizar o processamento de documentos. Ela suporta conversão entre formatos (PDF, DOCX, XLSX, PPTX, HTML e imagens), extração de texto e tabelas, OCR em documentos digitalizados (com mais de 100 idiomas), redação de informações sensíveis (como PII usando presets ou regex), adição de marcas d'água, assinatura digital (CMS) e preenchimento de formulários PDF. A comunicação é feita via requisições POST multipart para `https://api.nutrient.io/build` com um campo JSON `instructions`. A skill também oferece um servidor MCP alternativo para integração nativa com ferramentas. É útil para desenvolvedores que precisam automatizar tarefas comuns de processamento de documentos em aplicações, como converter faturas, extrair dados, redigir informações pessoais ou assinar contratos programaticamente.
