What to look forward to
This advanced evening for experienced agent builders will feature hands-on discussions of tools, harnesses, workflows, evaluations, autonomy, and real-world access, plus a demo of an agent using a permissioned wallet. Attendees will exchange practical lessons and connect through structured, interest-based conversations.
Inside the event
An evening for people who build with agents every day: swap workflows, compare setups, and meet builders at your level. Presented by Nuri.
TL;DR
- Advanced focused: This is not for beginners. We won't focus on covering basic concepts.
- Discuss & exchange: Tools, workflows, and lessons learned from building with agents.
- Structured Connections: We connect you with people relevant to you, based on what you tell us at registration.
Agenda
- Intro Welcome and a quick overview of what we're doing tonight.
- Nuri demo (5 min) Letting an agent pay: permissioned access to a real wallet. A demo, not a pitch.
- Topics & Discussion Short slides, demos, and open discussion. The topics below are starting points — we pick together on the night where to go deep.
- What changed since August — New models and tools since our last advanced evening. What did you switch to, and why?
- Harnesses & Custom Tooling — Claude Code, Codex, Pi — or building your own harness and agent tooling.
- Interfaces — CLIs, desktop apps, custom UIs — and agents in shared channels: is the channel the new interface?
- Environments & Going Local — Local, managed cloud, VPS/intranet; self-hosting and running open-source models.
- Workflows & Evals — How you structure agent workflows, when an agent vs. a plain API call, and how you know it's actually working.
- Autonomy & Real Access — What you let run unattended, multi-agent setups, and how far you let agents touch accounts, money and production.
- + Your topics — Open for suggestions. Bring what you want to discuss.
- Structured Connections We create a setting to connect you 1-on-1 with others who share your interests and topics.
- Drinks & Connect Open conversation over food and drinks, thanks to Nuri. We close the space around 21:00 and continue at the nearby "Trödler" bar.
