The playbook for AI agent integration is becoming predictable: build an MCP server, expose your APIs as tools, and define the rules in prompts. That approach works, but it often pushes workflow and guardrails into client-side logic, where they are harder to enforce and easier to bypass. This talk presents a different approach. HATEOAS (Hypermedia As The Engine Of Application State)—a largely overlooked part of REST—allows an API to describe allowed actions and constraints at runtime. That makes it a natural fit for agents, which need clear, machine-readable guidance about what they can safely do next. We’ll show this in action with MoneyMate, an AI agent that performs sensitive operations such as money transfers. Using the Spring HATEOAS project, the agent is guided entirely by the API rather than by hardcoded tools or fragile prompt logic. AI hype aside, this is ultimately a talk about architectural validation. For years, HATEOAS was the hill REST purists loved to die on—complete with finger-wagging about “doing REST correctly”—while everyone else quietly shipped simple JSON and moved on. It turns out the purists weren’t wrong—just 20 years early. Come see why that extra structure finally pays off when your client is an LLM. **About the venue** Free Times Cafe has bistro-style seating and a full food and drink menu. Please consider helping to support the venue by planning to have supper during the talk. **Speaker Bio** Adib Saikali is a distinguished engineer at Tanzu by Broadcom, focused on helping Tanzu’s largest customers design and build cloud native applications and platforms using Spring and Kubernetes.

**This is a ticketed event. Please register at [this link](https://luma.com/gprawfks).** In this talk, Sheikh Abdur Raheem Ali: 1) Discusses rare cases where deployed LLMs have been observed to engage in self-directed behavior which would have led to catastrophic outcomes if the agent escaping containment were equipped with stronger capabilities. 2) Introduces arbitrium, a peptide-based communication method used by certain bacteriophages which release small molecules known as autoinducers to decide coordinated population-level behavior, and in particular lytic and lysogenic pathways, with a quorum-sensing mechanism. 3) Explores landmark results from alignment science which inform our current understanding of LLM biology (<250 malicious documents required to poison training datasets vs <100 viral particles required to produce infection in humans). 4) Analyzes early findings from experiments which attempt to investigate scalable improvements to defenses that monitor the internal activations of production transformer models (such as probes) and demonstrates how these enable targeted interventions on known distributions which are more difficult to achieve with input/output only methods (such as prompted classifiers) in certain cases (such as long context windows or latent reasoning models) ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/xwjDdVSw3E **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code.
