On 'help me add evals to my RAG chatbot for CI', the baseline free-hand answer was four vague bullet points ('write some tests', 'consider using an LLM to grade'); the skill run named the RAG-specific Ragas quartet, gave a runnable promptfoo config with a CI-gating exit code, and added the judge-calibration step (hand-label ~30 examples, check agreement) the baseline never mentioned.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 9/10
  • Docs & honesty 5/5

What Add LLM Evals does

A methodology skill (no bundled scripts) for adding evaluation - not just tracing - to an LLM/agent app: pick reference-based vs LLM-as-judge per metric, curate a 20-100 example dataset, wire threshold-gated checks into CI via promptfoo/DeepEval/Ragas, then optionally add production LLM-as-judge scoring. Triggers on 'add evals', 'test my prompt', 'is my RAG accurate', or setting up an eval suite in CI; explicitly distinguishes itself from tracing/observability asks.

Commands — how to trigger Add LLM Evals

  • /add-llm-evals Playbook for wiring reference-based + LLM-as-judge evals into CI, with judge-calibration steps and named anti-patterns.

It also activates on plain-language prompts like these:

  • Help me add evals to my RAG chatbot to catch regressions in CI
  • Is my LLM app actually accurate? I want to test it before shipping
  • How do I catch prompt regressions before they hit production?
