Templates cover safety (prompt injection, PII, bias), response quality, agent trajectory, user behavior, and multimodal evaluation. They work for both online monitoring and offline experiment runs. The new Evaluators tab lets teams build an evaluator once and attach it to multiple tracing projects without maintaining duplicate copies. The templates are also available in openevals v0.2.0, which adds multimodal support for voice and image outputs. ## Full article daily.dev links to this article rather than hosting it.
