Topics include SBCE as a lightweight skill file, token economy savings of 30-80% via convention over configuration, live demos generating a Quarkus MicroProfile component and a static web site with BCE, local LLM inference via Light Metal (Llama.cpp + Java 25), the zsmith pure-Java 25 agent framework with virtual threads and JFR events, LLM-assisted legacy migration using SDD and OpenRewrite, CQRS/event-driven patterns with Kafka and DynamoDB, and standards-based CSS with design tokens served by a zero-dependency Java 25 web server. ## Full article daily.dev links to this article rather than hosting it.
