Your agent is only as good as the harness around it.
Anyone can call a model. The teams shipping agents that actually work are not writing better prompts - they are engineering the rig: the eval loops, the tool orchestration, the context budgets, the recovery when a step fails, that rig is the harness. That is what we build together for an afternoon.
The Agent Harness Symposium is a half-day workshop plus hackathon for people who build agents. Bring a laptop and one workflow that breaks in production, leave with a working harness.
How the day runs:
-
Gathering and lunch
-
Workshops - hands-on sessions on agent harness design
-
Building time - you ship, we help, the room compares notes
