AI Agents Co-working #3: Context Engineering & Multi-Agent Systems
Event description:
Why Context Engineering & Multi-Agent Systems?
You can build a single agent in an afternoon. Making it actually useful? That's where most people get stuck.
Two concepts separate toy demos from production agents:
Context Engineering
Multi-Agent Systems
These two concepts unlock everything else. Nail them, the rest is details.
What We'll Cover
Context Engineering
What actually goes into the context window (and what shouldn't)
The "context budget" mental model — how to think in tokens
System prompts that work vs. prompts that fight the model
Managing conversation history without blowing up costs
When to retrieve vs. when to summarize vs. when to forget
Multi-Agent Systems
When one agent isn't enough (and when it is — don't overcomplicate)
Three patterns that work: handoff, parallel, hierarchical
How agents talk to each other without spaghetti code
Debugging multi-agent flows (the hard part no one talks about)
Live example: two agents coordinating on a real task
Format: Co-working, Not Lecturing
This isn't a 2-hour presentation. It's a working session.
10-15 min: Quick walkthrough of core concepts
30-40 min: You build. We help. Bring your project or start fresh.
15-20 min: Show & tell — see what others built
Ongoing: Hang out, ask questions, meet other builders
Bring your bugs. Bring your half-finished projects. Bring your "why doesn't this work" questions.
Who Should Come
You've built a basic agent but it keeps breaking in weird ways
You're trying to connect multiple agents and it's turning into spaghetti
You've heard "context engineering" everywhere but don't know what it actually means
You want to build alongside people solving similar problems
Some Python experience helps. Laptop required.
Before You Come
Install Python 3.10+
Optional:
pip install connectonionOptional: Check docs at https://docs.connectonion.com
Bring your laptop + your favorite IDE (Cursor, VS Code, whatever)
Have a project idea in mind — or just come and see what others are building
About the Host
I'm Aaron (Onion). 7 years in ML/NLP. Built three AI agent products with LangChain, OpenAI SDK, ADK — and learned what actually matters the hard way. Built ConnectOnion to strip away the complexity. Now I run weekly co-working sessions so you don't have to figure this out alone.

This is Session #3
Every Saturday 2pm @ UNSW MCIC. Each session covers different topics, but you can join any week. We're building a community of developers who believe AI agents should be simple, powerful, and under your control.
