EP34 | Harness Engineering, and the Configuration Drift Problem With Defender

David is away this week, so it is just Richard and Cyrus. The episode ended up covering more ground than planned, and a couple of conversations went in directions that were not on the outline and were probably better for it.

Richard opens with harness engineering, the concept he thinks explains why AI agent projects look so good in the demo and fall apart in production, then moves on to Agent 365 going generally available and what it does and does not actually provide. Cyrus has a segment on Defender antivirus and Intune that reframes a question most security teams are asking in a way that is, in Richard's view, considerably more useful. And there is an unplanned conversation about vibe coding and SonarCloud that produced a finding neither of them had expected.
