## What Jamie wrote

This is a more interesting read on Mythos and why it is better than the average coding agent at finding security issues. I specifically like the walk through of the vulnerability discovery harness. It makes sense that a coding agent, which relies heavily on its agent harness, would not be as powerful as a specific vulnerability discovery harness.
