Outline - Harness Engineering: How to Build Software When Humans Steer and Agents Execute

Speaker

Ryan Lopopolo

Abstract

[inferred from filename and transcript] Harness Engineering: How to Build Software When Humans Steer and Agents Execute is an AI Native DevCon session covering harness engineering, human steering, agent execution, software delivery with agents, and agent workflows.

Thesis

[inferred] The talk's main contribution is its framing of harness engineering, human steering, agent execution for practitioners working with AI-native software development.

Transcript Status

The source is timestamped speech-to-text output. Speaker labels, punctuation, and some technical terms may be imperfect. Use timestamps when citing.

100:00-03:22Opening and framingWe've only got a few sessions left this afternoon, and then it's party time, I've been told.
203:25-07:18Main discussion 1my priors of what even is possible to achieve with these tools.
307:21-11:04Main discussion 2constraint, that context windows are continually being emptied and filled.
411:08-14:59Main discussion 3I never want to give the same review feedback twice, and this is really the core of what harness engineering is.
515:03-18:38Main discussion 4over to something halfway across the code base without any loss of quality or intelligence.

722:20-25:57Main discussion 6These functions cannot possibly be exercised because the unknown types can exist, and we get more aligned code, more aligned code that I would consider acceptable, high quality, m…
825:57-29:35Closing pointsvibe coding is a big part of what it takes to be successful here, because there's a ton of guardrails that only affect my local development process.
