How Microsoft Agent Framework can use Orb Platform

Vocabulary tools for the production-ready convergence of AutoGen and Semantic Kernel

The Scenario

Microsoft Agent Framework merges AutoGen’s simple agent abstractions with Semantic Kernel’s enterprise features — session-based state, type safety, middleware, telemetry. RC for .NET and Python, GA targeting Q1 2026. A developer registers Word Orb, Lesson Orb, and Quiz Orb as agent tools. Graph-based workflows route word → lesson → quiz automatically. MCP and A2A protocols supported natively.

Step 1 — Word Orb looks up the word
One API call returns a verified definition, translations, pronunciation audio, and etymology.
Loading word data…
Step 2 — Lesson Orb delivers a structured lesson
A 5-phase lesson (hook → story → wonder → action → wisdom) with the strategist teaching archetype.
Loading lesson data…
Step 3 — Quiz Orb assesses comprehension
Assessment questions aligned to the lesson content through the knowledge graph. Your agent tests what it taught.

Step 4 — The Knowledge Graph connects everything
30,288 connections link words to lessons to assessments. Every quiz question tests what the lesson taught.
