On: So, you want to chunk really fast?

[brene]

Do you see this project merge with the Chonkie at some point? Or do you intend to keep it separate?

[snyy → brene]

Memchunk is already in Chonkie as the `FastChunker`

To install: pip install chonkie[fast]

``` from chonkie import FastChunker

chunker = FastChunker(chunk_size=4096) chunks = chunker(huge_document) ```

How does it deal with loops? I’ve often see workflow builders struggle at that?

[waleedlatif1 → brene]

for loops we use two sentinel nodes with a backwards edge, and before each iteration, we check the condition and update loop variables.

  sentinel -> body -> sentinel (condition with backwards edge to first sentinel)

in the UI, this is just represented as another block, and depending on the varying types of loops you can either define a collection or the number of iterations

[Natfan → brene]

and specifically nested loops. if you're spinning up full runtime copies for each loop, you're gonna have a hard time

[waleedlatif1 → Natfan]

at the moment, we don't support 'loops in loops' on the client-side, but not for any other reason asides from it becoming confusing for users. since we don't actually make copies for each loop, it wouldn't be a performance issue.

I actually wonder is there a way to feed back some consistently reedited code into the context window of your coding agent tools, so that future edits require less tokens?

[addcn → brene]

Interesting idea. We are exploring a Git AI MCP now. Hopefully a lot of this data can raise the agent’s IQ a few points.

On: Show HN: Prism – Let browser agents access any app

Hi Rene from Casco here. I think the post just referenced us as a customer because we use it for pentesting. For us, Prism solves the "browser agents can reliably auth into any website" problem.

On: Show HN: Prism – Let browser agents access any app

[brene]

Hi - Rene from Casco here. Thought to share a bit about our journey of dealing with auth for browser agents before Prism. We have a diverse set of customers whose login experience differ dramatically. Sometimes it's directly accessible on request, other times, you have to click through into a "login menu", other times we'd be dealing with Google sign-in and OTP.

We initially tried manually uploading session cookies to our browser agent after we authenticate locally. But soon realized how unscalable that is. We needed a general purpose API that allows our agents to auth into any application reliably. We needed something like Prism because making an agent reliable for our vertical is hard enough and I don't want us to maintain infrastructure just for the purposes of managing test user credentials and session management. If you're using browser agents and they've "hit the auth wall", then you know what I'm talking about.

Thanks for building Prism for us and letting us be a pilot customer. The API is straightforward and a pleasure to use. Can't wait for user sign-up and GitHub auth support to come soon.

It's a pleasure to work with you. Excited to expand to more login cases and support login to more websites.

On: Kiro: A new agentic IDE

[brene]

wait, it's completely free during the preview period? That's a better deal than Cursor, Windsurf, or Claude Code. Gotta check it out

On: Show HN: HelixDB – Open-source vector-graph database for AI applications (Rust)

[brene]

How does this scale horizontally across multiple regions. Is this something on your roadmap?

[GeorgeCurtis → brene]

It’s definitely on our roadmap, but not a priority because no one using us needs it. Is this something that would be useful to you?

On: Show HN: Airweave – Let agents search any app

[brene]

Pretty cool stuff. How does it deal with self-hosted data sources? can it run inside a VPC and talk to my RDS instances directly?

[raufakdemir → brene]

You can self-host Airweave on Docker or Kubernetes within your VPC. We eventually want to move towards AWS/Azure/GCP marketplace offerings that should make this easier for you. RDS should work - if you get an instance with PSQL/MySQL dialect.

On: Show HN: Sim Studio – Open-Source Agent Workflow GUI

[brene]

I checked it out and it’s quite polished for a workflow builder. But I struggled for it to handle lists of content well. But I saw that’s already an ongoing feature request.

[ekarabeg → brene]

Thank you! Yes - we are adding variable resolution to the for each input. Let us know if there's anything else you'd like to see!

On: Launch HN: Cua (YC X25) – Open-Source Docker Container for Computer-Use Agents

[brene]

will this also be available as a hosted service? Or do you have instructions on how to manage a fleet of these manually while you're building the orchestration workflows?

[frabonacci → brene]

Yes, we’re currently running pilots with select customers for a hosted service of Cua supporting macOS and Windows cloud instances. Feel free to reach out with your use case at founders@trycua.com
