The link text says "Training: Develop an AI agent with Microsoft Agent Framework" but the URL points to /training/modules/develop-ai-agent-with-semantic-kernel/, which appears to be Semantic Kernel training content. This is inconsistent with the PR's goal of removing Semantic Kernel references. The URL should be updated to point to Agent Framework training content if it exists, or the link should be removed if Agent Framework training is not yet available.

Suggested change
- [Training: Develop an AI agent with Microsoft Agent Framework](/training/modules/develop-ai-agent-with-semantic-kernel/)

- LLMs have token input limits that constrain the amount of text you can fit in a prompt. Use [embeddings](embeddings.md) and [vector database solutions](vector-databases.md) to reduce the number of tokens you need to represent a given piece of text.
- LLMs aren't trained on your data unless you train them yourself, which can be costly and time-consuming. Use [retrieval augmented generation (RAG)](rag.md) to make your data available to an LLM without training it.
- Creates an AI agent using a chat client configured for a specific model endpoint.
- Configures the agent with system instructions using `WithInstructions`.

The documentation states the code "Configures the agent with system instructions using WithInstructions", but the referenced code sample (multi-turn-chat.cs) doesn't actually call WithInstructions or demonstrate configuring system instructions. The code should either be updated to include system instructions, or this bullet point should be removed or modified to accurately reflect what the code demonstrates.
