Document-SDK-Skills

Document SDK Skills are specialized instruction sets that teach AI assistants how to perform specific tasks. Think of them as expert knowledge modules for Syncfusion Document Processing libraries that AI agents can load on demand. These skills follow the Agent Skills open standard and are designed to work seamlessly across multiple AI agents.

About This Repository

This repository contains AI-ready skills that empower AI agents to efficiently handle Office document processing tasks using Syncfusion Document Processing libraries across .NET, Java, JavaScript, and Flutter. Depending on the selected skill, agents can generate language-specific code for your project or create documents via supported script execution modes.

Getting Started

How to Integrate Skills

Step 1: Checkout and copy the required skills

Clone or download the Document-SDK-Skills repository and copy the product skills you need from the skills/ directory. Available skill folders include syncfusion-dotnet-pdf, syncfusion-dotnet-word, syncfusion-dotnet-excel, syncfusion-dotnet-powerpoint, syncfusion-dotnet-pdf-to-image, syncfusion-dotnet-markdown, syncfusion-dotnet-calculate, syncfusion-dotnet-smart-data-extraction, syncfusion-javascript-pdf, syncfusion-flutter-pdf, syncfusion-flutter-excel, and syncfusion-java-word.

Step 2: Install the skills

Place the copied skill folders in your workspace following this structure:

your-workspace/
├── .github/skills/                          # or .claude/skills/ or .codestudio/skills/
│   ├── syncfusion-dotnet-pdf/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-word/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-excel/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-powerpoint/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-pdf-to-image/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-markdown/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-calculate/
│   │   └── SKILL.md
│   ├── syncfusion-dotnet-smart-data-extraction/
│   │   └── SKILL.md
│   ├── syncfusion-javascript-pdf/
│   │   └── SKILL.md
│   ├── syncfusion-flutter-pdf/
│   │   └── SKILL.md
│   ├── syncfusion-flutter-excel/
│   │   └── SKILL.md
│   └── syncfusion-java-word/
│       └── SKILL.md
├── your-project-files...
└── Program.cs

Each skill directory must contain a SKILL.md file that defines the skill's behavior.

Step 3: Verify and manage your skills

Type /skills in the GitHub Copilot or Code Studio chat to quickly access the Configure Skills menu and manage your installed skills.

Step 4: Use skills

There are two ways to use skills:

1. Automatic loading - Simply describe your task naturally, and your AI Agent automatically loads the relevant skill:

   Create a Word document with company letterhead and a data table
   Add a digital signature to the PDF at output/report.pdf  
   

2. Slash commands - Type / in the GitHub Copilot chat to mention available skills. For example:

   /syncfusion-dotnet-word Create a report with a table of contents
   /syncfusion-dotnet-pdf Merge multiple PDFs into one
   

When a skill is loaded, AI Agent gains specialized knowledge of Syncfusion Document Processing libraries and can help you generate code or execute supported document operations efficiently.

Prerequisites

Install the runtime required by the selected skill:

• .NET skills: .NET SDK 8+ (dotnet --version)
• .NET execution-mode skills only: dotnet-script (dotnet tool install -g dotnet-script)
• Java skill: Java SE 8 or later
• JavaScript skill: Node.js/npm

Use the latest compatible package versions from pub.dev or Syncfusion documentation, then run: flutter pub get. Add syncfusion_officechart when chart support is needed.

How it works?

Skills support one or more operating modes depending on product and platform:

Mode 1 — Generate Code (default)

Produces production-ready code for the selected platform, such as C#, Java, Dart, TypeScript, or JavaScript. No scripts are created or run. Ideal when you want to learn or integrate document features into your own application.

Trigger keywords: "code", "snippet", "how to", "show me", "sample", "example", "Program.cs", "main.dart"

Mode 2 — Execute via Temporary Script (supported skills only)

For skills that explicitly document execution mode, creates a temporary script, runs it, produces the output file, then cleans up — without touching your project. .NET execution-mode skills use .csx and dotnet script.

Trigger keywords: "create", "generate", "make", "open", "edit", "modify", file paths (e.g., output/report.docx)
