Building Safer AI Agents with Structured Outputs | Snyk

Not everything needs to be a chatbot.
Parsing free-form LLM output after the fact is building on quicksand.

Use REAL structured output. Schema-enforced generation. No β€œplease respond in JSON” hacks.

Combine this Snyk Code + Snyk EVO in AI-driven workflows.

I love how you can use JBang to make MCP servers easy available to everyone.

Add jbang javaconfmcp@bmvermeer/javaconfmcp to your AI assistent to ask about upcomming Java events or closing CFP's

Nice thanks. @ericdeandrea.dev
I will do some experiments with it next week.
Lets see if I am smart enough to understand how you implemented this :)

Pro tip for everyone submitting to tech conferences.

Include a video of a previous talk or create one pitching your talk.

Delivery is just as important as the topic.
Don't assume the program committee is familiar with you. You need to convince the PC that your submission is of sufficient quality.
