Session Description

Tired of searching for the right tool(s) for your agents? Seeing your context window constantly blowing out of proportion? We are introducing a new product category that allows developers to choose the right toolset depending upon the agents' context, the use-case and functional boundaries, enabling efficient use of tools, with built-in governance.

Seating for this session is first-come, first-served. Add it to your schedule to plan your day and arrive early to secure a spot

Turn Your Agents Into Action

Why: Today, most agents look impressive in demos—but break in production. They rely on bloated prompts, fragile integrations, and struggle with real-world data like PDFs, receipts, or emails. In this session, we'll share how to move beyond prompt-based agents to real systems that act. Sharing how to connect agents to tools, automate workflows across runtimes, and handle messy, unstructured data with confidence.

Problem: Today, most agents look impressive in demos—but break in production. They rely on bloated prompts, fragile integrations, and struggle with real-world data like PDFs, receipts, or emails. In this repo, we'll show how to move beyond prompt-based agents to real systems that act. You'll learn how to connect agents to tools, across agent runtimes, through a single endpoint with Toolboxes, and how — with Content Understanding — you can work with unstructured data with confidence.

What is a Toolbox

Toolbox bundles everything an agent needs into a reusable package—delivered through one endpoint with a consistent interface, no matter the tool type, managed on Foundry.

What tool types does Toolbox support? Toolbox is designed to be tool-agnostic:

What is Content Understanding

Azure Content Understanding in Foundry Tools turns unstructured, multimodal content into reliable, structured outputs you can automate against. Content Understanding uses a consistent Parse → Classify → Extract taxonomy across documents, images, audio, and video:

• Parse — normalize raw content into usable structure: text, layout, tables, transcription, and visual elements.
• Classify — identify document or content types, route content, and segment it when needed.
• Extract — produce schema-based fields (JSON) or markdown with confidence scores and grounding.

Built on the foundation of Azure Document Intelligence. Azure Content Understanding brings together Document Intelligence's industry-leading OCR, layout, and table-extraction technology — refined over many years — and extends it with LLM-powered multimodal capabilities across audio, video, and image. If you've trusted Document Intelligence for documents, Content Understanding is the natural next step: the same proven engine, now with one schema-driven API for every modality. Document Intelligence remains GA — there's no forced migration; new content-to-JSON projects should start with Content Understanding.

🚀 Deep Dive: Check out the Fiberly demo with Content Understanding integrated (fiberly-agent-cu repo) to see these patterns in an end-to-end agent experience.

Content Understanding helps agents with stronger grounding, real-time context, and business-ready extraction:

• Better grounding for RAG — with Foundry IQ as standard, Content Understanding parses PDFs at index time, preserving structure like tables, headings, and figures.
• Real-time context provider — parses incoming files as the agent runs, keeps structure intact for more accurate answers, and supports a wider range of file types.
• Business-specific extraction — uses analyzers you define for target document types (for example, invoices, work orders, or contracts) so files can be classified, routed, and parsed for the exact values you need.

A tool lets an agent take action; Content Understanding provides the context behind that action with minimal configuration and at agent scale.

🚀 Getting started

If you're following these steps at your own pace:

• Clone this repository
• Set up your development environment
• Explore the resources in this README and use the Copilot prompts below to design your own agent integration approach

🧠 Learning Outcomes

By the end of this session, you will be able to:

• Evaluate which tools, APIs, and document sources are best suited for different agent scenarios
• Design agent boundaries that keep context efficient and reduce unnecessary token usage
• Apply governance-oriented patterns when connecting agents to external systems and enterprise knowledge
• Use Content Understanding to turn multimodal, unstructured content into structured, agent-ready inputs

💬 Keep Learning with Copilot

Try these prompts with GitHub Copilot to explore the topics from this session. Open Copilot Chat in VS Code (Ctrl+Alt+I on Windows/Linux, Cmd+Shift+I on Mac), paste a prompt, and see what you learn. Try connecting the Microsoft Learn MCP Server for the latest official documentation.

Use these as a starting point — or write your own!

Try prompts like:

• "Help me design an agent tool strategy for a customer support scenario using APIs and documents."
• "Compare when to call an API directly vs. route through a tool abstraction in an agent workflow."
• "Show me a practical pattern to keep agent context windows small while still grounding on documents."
• "Generate a governance checklist for agent tool access, data boundaries, and auditing."
• "Walk me through how Content Understanding builds on Document Intelligence, and when I should pick one over the other."
