## Signals and evidence

## TESIGN TAKE

Because it needs no AI and gives repeatable results, it suits re-running after every fix.

## WHY IT MATTERS

Writing tests is a chore, so many changes ship unchecked. assay finds every control on the page, uses all of them, and reports what went wrong.

## BUILD FROM THIS

- It opens the page in Chromium and builds its checks from the controls it finds. If pressing a tag filter twice leaves the list filtered, it reports that with before and after views. No test code, no LLM, no API key, and every run gives the same result. A skill for coding agents is included.

## WHO IT'S FOR

- Developers who want to check their own web pages before shipping.

## START IN 5 MINUTES

```
# Install with pip install assay-ui and run it on the address of the page you want to check.
```

## CAVEATS

- Needs Python and Chromium. Recently released, with 98 stars.

## How to read this

- This file was produced by the same build, from the same data, as the tesign.com item page. The text is editorial; the numbers are stored observations.
- null in the JSON means not observed — never zero. The Markdown writes [unconfirmed] for it.
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.
- A summary, not legal advice.
