Ahh, got it. I didn't realize HN did that. Thanks for letting me know! That probably explains it :)

I shipped a QA harness for Claude Code. Instead of clicking through flows by hand, it reads your code diffs, identifies the affected UI flows, and tests them in real browser

Plus after each run you get screen recordings with console logs, network requests, HARs, and Playwright traces so you can inspect exactly what the agent did :)

P.S. I attempted to do a Show HN but got flagged for some reason

Just CC cruso@cruso.app on any email thread and it handles the rest

Show HN: Transform Unstructured Data into Usable Datasets

wizenheimer — Tue, 03 Sep 2024 04:57:11 +0000

Current tooling around running evaluations, performing fine-tuning are broken. They are built by optimists, dreamers, and in many cases, brilliant engineers. But they're building tools for a world that doesn't exist - a world where data comes in as pre-cleaned JSONs that are perfectly labeled and ready to use.

Cyyrus transforms unstructured data into usable datasets. We want to do for datasets, what Terraform did for infrastructure.

The current package is experimental and built over the weekend to understand if terraforming datasets is viable. Terraform made infrastructure sexy. We believe a tool like Cyyrus can make data transformation sexy as well.

Would love to know if our approach resonates with you? Or is it completely off base :D

> I don't understand the "Chrome" part at all

It uses, relies and depends on Chrome exposed primitive such IndexedDB. Hence the term chrome native.

Honestly, didn't give much thought to it. Just rolled with it :D

Imagine this. You stumbled across this insane search technique, which knows what you want. It doesn't care if you know the exact keywords or not, it just gets what you're after. We call it Vector Search / Semantic Search. Cool stuff right? You don't have to be a keyword wizard to get your stuff. But there's a problem.

Unlike it's keyword search counterpart it expensive. Order of magnitude expensive. All because you need to maintain a vector search index and keep it available server side.

Enter Tinkerbird. This little library takes the heavy lifting and pushes it client side. Stream your embeddings, front it via CDN or cache it on client. Now you get benefits of vector index without the costs of maintaining one.

Thanks, mate. I guess the README is dated. Here's a sample app built around tinkerbird. Make it yours :D
