LLM Evals Starter Kit: Know If Your AI Got Worse Before Your Users Do
by Avanish patidar
$19
Introduction
"It looked good when I tried it" is not a measurement.
You change a prompt on Friday. Did it get better, or did you break the thing that worked on Tuesday? Without an eval you find out from your users. This kit sets one up in an afternoon.
Who is this for?
- You have an AI feature in production, or close to it, and no way to measure it.
- You have heard "use LLM-as-judge" and want a judge you can actually trust.
- You want the files, not a 40-hour course.
What's inside
- ✅ golden-set-template.csv: a spreadsheet for your test cases, with example rows
- ✅ golden-case.md: one case written out in full
- ✅ rubric.md: five dimensions scored 1 to 5, with what a 3 and a 5 look like
- ✅ llm-as-judge.md: the judge prompt, which must quote evidence for every score
- ✅ judge-check-20-samples.md: how to check the judge against a person
- ✅ release-blockers.md: what blocks a release, written down once
- ✅ An 8-page guide that explains each part, with a worked example and a 10-item checklist
One afternoon, in order
1. Two hours: fill 30 rows with real inputs.
2. Thirty minutes: rewrite the rubric examples for your product.
3. Thirty minutes: run the judge on 30 outputs.
4. One hour: score 20 by hand and compare.
5. Ten minutes: write down what blocks a release.
Includes: 2 files, PDF and ZIP.
Already own the Playbook?
Then you have most of this. The guide is Chapter 4 of Ship AI Products That Survive Production. The spreadsheet, the rubric file and the judge-check sheet are the new parts. Buy this only if you want evals on their own.
Final notes
If it helps, a rating takes ten seconds and is how other builders find it.
