AI agents have two architectural layers: a deterministic core you control and a probabilistic LLM you don't.
@andychiare breaks down why securing the code around your model matters more than securing the model itself:

Stop confusing "Tools," "MCP servers," and "Skills" in AI. Their interchangeability creates terminological ambiguity, making AI agents harder to secure.
The following table summarizes the differences.

Effective AI agents balance two "souls": probabilistic LLMs and deterministic code.
While LLMs get the hype, traditional code is vital for security and stability.
I discuss the two souls of an AI agent in my latest blog post: auth0.com/blog/ai-agents-hav…

Bring @aspiredev to your existing app without rewriting it.
In 13.3, aspire init adds the AppHost skeleton, then /aspireify helps wire your app into the Aspire model using project context. This doesn't change your application, it just describes.

PKCE and BFF aren't alternatives. They solve different problems.
If you've been assuming PKCE is enough for SPA security, this is worth reading: auth0.com/blog/things-develo…

I believe that the primary purpose of using AI to develop professional production-ready software should be to improve quality rather than increase speed.
Speed will be a side effect, an added bonus.
If you focus on speed, I'm not sure you will get a better product.
