01 What is it?
Promptfoo and DeepEval are the open-source evaluation harnesses for prompts, agents and RAG pipelines. They support deterministic and LLM-as-judge evaluators, run in CI like any test suite, and produce structured reports that make regression visible before code lands.
02 Why implement it?
- Run like any test suite, native to CI/CD
- Built-in evaluators: factuality, safety, latency, cost
- LLM-as-judge with the model of your choice
- Compare prompts, models and configurations side by side
- Open source, self-hostable, no vendor lock-in
03 How I help
I design evaluation harnesses for your agent and RAG pipelines, wire them into CI, define custom evaluators for your domain, and set the regression gates that block bad changes from reaching production.
04 Expected deliverables
- Evaluation harness for prompts, agents and RAG
- CI integration with regression gates
- Custom evaluators for your domain
- Reporting dashboards and review cadence
- Team enablement and operating model
