Eval results

An eval run case by case, against the run before. Free and MIT licensed, as HTML or a typed React component, in two styles with light and dark mode.

$npx designme add eval-results
Pricing copy evalsCopy agent · 8 cases · run 2h ago
01

Install

Add it to your project with the CLI.

HTML, CSS and JavaScript

$npx designme add eval-results

React

$npx designme add eval-results --react

The CLI copies the source into your project, so you own it and can change anything. The HTML version lands in ./designme with the shared core and a demo.html. The React version lands in src/components/designme and needs React 19; it works in Next.js, Vite and Astro.

02

About

What it is for and what it does.

Eval results shows an eval suite's latest run case by case. A bar with one segment per case fills as the cases run, the pass count is compared with the run before, and a filter narrows the list to the failed cases. A failed case opens to show what was expected, what came back and where the answer comes from, with a fix that runs it again.

  • When an agent's output is checked by a set of evals and people need to see which ones failed, not just a score.
  • When a change to a prompt, a model or the agent's work should be compared with the run before, to catch a regression.
  • When a failure needs its evidence, expected against what came back, to be fixed.
  • When the suite is long and people only want the failures.
03

Usage

Import it and drive it from your own state.

Import

import { EvalResults } from '@/components/designme/eval-results/EvalResults';

Example

The demo above as a React component, 58 lines you can copy.

Questions

What people ask about it.

Does it run the evals?
No. onRun tells you to start. Set each case's status as your eval runner reports it, and running for the whole run.
What does the fix button do?
Whatever you pass as its onClick. In the demo it changes the copy to the billing table's price and runs that one case again.
Can it show scores instead of pass and fail?
Not yet. Each case passes or fails; put a score in its name or time if you need one there.
How does it compare with the last run?
By the number that passed. Pass previousPassed from your last run, and the tag appears once every case has a result.
