Lunch & Hack Online Series - What is Harness Engineering? + Free OpenAI Credits (w/ The AI Collective)
Virtual Lunch & Hack
Join us for a Virtual Lunch & Hack, a biweekly online event where builders come together to learn something new, hear from great speakers, and hack on a fun project in real time.
Each session features a different topic. We’ll kick things off with a short talk from our speakers, followed by a hands-on hacking session where everyone gets a chance to build. At the end, selected participants can show what they made.
For this session, we’ll learn about Harness Engineering!
As part of the event, attendees will receive free OpenAI API credits to experiment during the session, and you'll have the opportunity to showcase what you've built at the end.
AI coding assistants can generate code fast - but without the right system around them, the results are unreliable. "Harness engineering" is the discipline of building that system: the context, planning, workflows, and validation loops that turn AI coding assistants into a reliable tool for shipping real, production-ready code.
In this session I'll break down what an AI coding harness actually is and the core loop I use to get reliable results - Research, Plan, Implement, Validate. Then we'll put it into practice with a live group hack where you'll apply the loop to a real task using whatever AI coding assistant you already work in, and wrap up with a show & tell of what everyone built.

Cole Medin
Founder of Dynamous, an AI engineering education platform. He creates content about AI coding and agentic systems for over 200,000 developers and entrepreneurs on YouTube, and runs the Dynamous community where engineers learn to build reliable AI-powered workflows. Cole's approach focuses on systematic processes over tool hype: capabilities over tools, systems over hacks. More at https://youtube.com/@ColeMedin
Adelina Martiniuc
CEO of RoryPlans.ai and the creator of RoBrain.dev, Adelina has over 15 years of experience in tech, including leadership roles at Vercel, Cruise, and Google. She wrote her thesis on AI planning and optimization 15 years ago, exploring agent-based systems long before they were widely called “agents.” She is currently building Rory, a multi-agent orchestrator that aligns human teams and AI agents in a single system of execution. RoBrain is a shared memory across your team and your AI agents, with judgment about what's worth keeping.
The AI Collective is a global non-profit building the human layer for the AI era. We unite 200,000+ leaders, builders, and stakeholders across 100+ forums worldwide to democratize the frontier, build trust, and coordinate how society navigates the rapid acceleration of technological progress.
