Checkpoint: Evaluation and Observability

  • I can define task success metrics.
  • I can unit test individual tools.
  • I can run integration tests for an agent flow.
  • I can inspect traces and logs for a failed run.
  • I measured quality, latency, cost, and failure rate.
  • I can compare two prompt or model versions on the same eval set.
  • I can evaluate retrieval separately from answer generation.
  • I can label failures by root cause: model, prompt, tool, retrieval, orchestration, or policy.
  • I can design a human review rubric for subjective or high-risk outputs.

Practical Check

Before moving on, build a small evaluation suite for one agent:

  • at least 20 realistic cases,
  • expected behavior for each case,
  • one answer-quality rubric,
  • tool-call or retrieval assertions where relevant,
  • latency and cost tracking,
  • trace IDs for failed runs,
  • a short report comparing two agent versions.
