10:59:17 +0300 Subject: [PATCH 2/2] feat: add LLM-as-Judge agent evaluation sample Adds a complete evaluation pipeline demonstrating production-grade agent quality assessment using specialized judge agents with rubric-based scoring. ## What's included - Jupyter notebook with full evaluation pipeline - 4 judge dimensions: Correctness, Completeness, Clarity, Safety - Parallel judge execution via asyncio.gather - 8 diverse test cases (general knowledge, code gen, security, safety) - JSON dataset format for extensible test cases - Report generation with per-judge averages and per-category breakdowns - CI/CD-ready JSON output (eval-report.json) - README with architecture diagram and production considerations - .env.example for multi-provider configuration ## Why this matters The 08.EvaluationAndTracing directory has DevUI visualization and tracing but was missing its namesake: evaluation. This sample fills that gap with a production pattern that is directly applicable to CI/CD pipelines. --- 08.EvaluationAndTracing/README.md | 31 +- .../python/llm_judge_evaluation/.env.example | 13 + .../python/llm_judge_evaluation/README.md | 53 ++ .../datasets/sample_eval_cases.json | 60 ++ .../llm_judge_evaluation.ipynb | 565 ++++++++++++++++++ .../llm_judge_evaluation/requirements.txt | 2 + 6 files changed, 719 insertions(+), 5 deletions(-) create mode 100644 08.EvaluationAndTracing/python/llm_judge_evaluation/.env.example create mode 100644 08.EvaluationAndTracing/python/llm_judge_evaluation/README.md create mode 100644 08.EvaluationAndTracing/python/llm_judge_evaluation/datasets/sample_eval_cases.json create mode 100644 08.EvaluationAndTracing/python/llm_judge_evaluation/llm_judge_evaluation.ipynb create mode 100644 08.EvaluationAndTracing/python/llm_judge_evaluation/requirements.txt diff --git a/08.EvaluationAndTracing/README.md b/08.EvaluationAndTracing/README.md index 91c341c..06a6c62 100644 --- a/08.EvaluationAndTracing/README.md +++ b/08.EvaluationAndTracing/README.md @@ -6,12 +6,31 @@ Of course.
