Hamel Husain

Hamel Husain has open-sourced a set of 'eval skills' for coding agents, drawn from observations across 50+ companies and 4,000+ students, to help teams systematically audit and improve their AI evaluation setups. The centerpiece is an eval-audit skill that runs diagnostic checks across six areas and surfaces prioritized problems. As coding agents increasingly run experiments and instrument production systems, the quality of your eval infrastructure directly determines how reliably and safely you can deploy AI.
