AI quality evals

Ads Manager AI evals

I helped make Ads Manager AI quality something reviewers, prompt partners, and engineers could evaluate: grounded answers, useful caveats, clear next steps, and observable failure modes for campaign-performance guidance.

Content move

Turned content design judgment into foundational evals, ad analysis quality rubrics, failure modes, and review standards.
