Part 1 of a four-part series covers scaffolding the project with the Auth0 .NET template, configuring GitHub Models (gpt-4o-mini) as the inference backend, implementing a tool-calling agent with session persistence via distributed cache, and wiring up a Blazor chat UI protected by Auth0 authentication. The agent can retrieve hardcoded expense reports and maintain multi-turn conversation state across renders. Future parts will add vector database integration, fine-grained authorization, Gmail tooling via Token Vault, and CIBA-based push approval flows. ## Full article daily.dev links to this article rather than hosting it.
