[Other] Show HN: AgentState – Lightweight state manager for multi-agent AI workflows AgentState to solve a problem I kept running into: managing state for multi-agent AI systems is surprisingly hard. When you have multiple AI agents that need to coordinate, persist their state, and query each other&#x27;s status, you typically end up with a mess of Redis&#x2F;Postgres setups, custom queuing, and manual synchronization code.<p>The whole thing is ~3MB, written in Rust for performance and safety, runs in Docker, and handles 1000+ ops&#x2F;sec. I&#x27;ve been running it in production for AI workflows and it&#x27;s been rock solid.

[Other] Show HN: Creao – Vibe coding product for founders Hi HN! I&#x27;m North, DevRel from the CREAO team. We are a 15-20 person startup, and we spent a couple of months building this vibe coding product. We&#x27;ve been exploring the possibilities of how agents should assist people&#x27;s work for productivity in various scenarios.<p>Three months ago, we noticed that all small teams and companies are struggling with subscribing to multiple SaaS tools that never fit their exact needs. Pretty much all founders and SMB professionals need customized productivity tools that fit their daily work routines, but they don&#x27;t have developers to build these lightweight tools for them. So we thought we needed to build a vibe coding product that allows them to ship their own tools in minutes and get rid of these SaaS subscriptions.<p>For our product features, we built it differently from all the other vibe coding products. We want our users to build something actually useful instead of just a product prototype. But the current well-known code agents are performing poorly at building complex data schemas and integrating APIs. So we fine-tuned a small model for the following features:<p>1.Automatically builds complex relational data schemas<p>2.Automated MCP&#x2F;API connections with existing systems<p>With these core capabilities, our code agent can then build internal tools that connect with existing systems with state persistence. For example, I built a dashboard to track my X engagement and export results to a CSV file.<p><a href="https:&#x2F;&#x2F;drive.google.com&#x2F;file&#x2F;d&#x2F;1FBBOdrtonlj_56jgQuAoPpGnABB-pvt2&#x2F;view?usp=sharing" rel="nofollow">https:&#x2F;&#x2F;drive.google.com&#x2F;file&#x2F;d&#x2F;1FBBOdrtonlj_56jgQuAoPpGnABB...</a><p>This productivity boost is specifically designed for small team founders—you can build your own CRM workflows, data dashboards, revenue tracking, etc. Each of these could cost you $20-50&#x2F;month in SaaS subscriptions.<p>We are still in the early stage and improving our user experience. Our team is delivering new features pretty much every week, and we would love to hear from HN to give us some suggestions on how we can do better. You can always reach me at north@creao.ai. I love to shape the product together with community users. I hope you can find our work very helpful for your productivity.<p>Thanks!

[Other] Show HN: AICF – a tiny "what changed" feed for AI/RAG (v0.1 minimal core) I’m proposing AICF (AI Changefeed) — a minimal, web-native way for sites to expose append-only change events. Instead of crawlers or RAG systems re-embedding everything, they can refresh only the sections that changed.<p>Discovery: a &#x2F;.well-known&#x2F;ai-changefeed JSON points to a feed.<p>Feed: an append-only NDJSON file with just 4 required fields (id, action, url, time) plus optional hints (anchor, checksum, note).<p>Goal: cut wasted crawling&#x2F;embedding while keeping docs&#x2F;pricing&#x2F;policy pages fresh for AI&#x2F;agents.<p>Spec &amp; examples here: <a href="https:&#x2F;&#x2F;github.com&#x2F;mnswdhw&#x2F;AICF&#x2F;blob&#x2F;main&#x2F;spec&#x2F;AICF-v0.1.md" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;mnswdhw&#x2F;AICF&#x2F;blob&#x2F;main&#x2F;spec&#x2F;AICF-v0.1.md</a><p>Would love feedback: is the minimal core (anchors only, no chunks&#x2F;vectors&#x2F;push yet) the right starting point? Would you use this in your docs&#x2F;RAG stack?

[Other] Show HN: JavaScript-free (X)HTML Includes (spoiler: its XSLT)<p>I&#x27;ve been working on a little demo for how to avoid copy-pasting header&#x2F;footer boilerplate on a simple static webpage. My goal is to approximate the experience of Jekyll&#x2F;Hugo but eliminate the need for a build step before publishing. This demo shows how to get basic templating features with XSL so you could write a blog post which looks like<p><pre><code> &lt;?xml version=&quot;1.0&quot;?&gt; &lt;?xml-stylesheet type=&quot;text&#x2F;xsl&quot; href=&quot;&#x2F;template.xsl&quot;?&gt; &lt;page&gt; &lt;title&gt;My Article&lt;&#x2F;title&gt; &lt;content&gt; some content &lt;ul&gt; &lt;li&gt;hello&lt;&#x2F;li&gt; &lt;li&gt;hello&lt;&#x2F;li&gt; &lt;&#x2F;ul&gt; &lt;&#x2F;content&gt; &lt;&#x2F;page&gt; </code></pre> Some properties which set this approach apart from other methods:<p><pre><code> - no build step (no need to setup Jekyll on the client or configure Github&#x2F;Gitlab actions) - works on any webserver (e.g. as opposed to server-side includes, actions) - normal looking URLs (e.g. `example.com&#x2F;foobar` as opposed to `example.com&#x2F;#page=foobar`) </code></pre> There&#x27;s been some talk about removing XSLT support from the HTML spec [0], so I figured I would show this proof of concept while it still works.<p>[0]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44952185">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44952185</a><p>See also: grug-brain XSLT <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44393817">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44393817</a>

[Other] Show HN: I integrated my from-scratch TCP/IP stack into the xv6-riscv OS Hi HN,<p>To truly understand how operating systems and network protocols work, I decided to combine two classic learning tools: the xv6 teaching OS and a from-scratch TCP&#x2F;IP stack.<p>I&#x27;m excited to share the result: my own from-scratch TCP&#x2F;IP networking stack running directly inside the xv6-riscv (<a href="https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;xv6-riscv-net" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;xv6-riscv-net</a>) kernel.<p>The project uses a modern virtio-net driver, allowing it to run seamlessly in QEMU and communicate with the host machine.<p>Key features:<p>- From-Scratch Stack: The core is powered by microps (<a href="https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;microps" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;pandax381&#x2F;microps</a>), a TCP&#x2F;IP stack I originally wrote to run in user-space as a personal project to learn the low-level details of networking.<p>- Kernel Integration: This project ports microps from user-space into the xv6-riscv kernel.<p>- Socket API: Implements standard system calls (socket, bind, accept, etc.) to enable network application development.<p>- User-level Tools: Comes with a simple ifconfig command, plus tcpecho and udpecho servers to demonstrate its capabilities.<p>This has been a fantastic learning experience. My goal was to demystify the magic behind network-aware operating systems by building the components myself.<p>I&#x27;d love to hear your feedback and answer any questions!

[Other] Show HN: Claudable – OpenSource Lovable that runs locally with Claude Code Hey, HN! I&#x27;m Aaron. I built an open-source Lovable for Claude Code users.<p>Platforms like Lovable, Replit Agent, and Bolt require separate API keys and $25+&#x2F;month subscriptions. But if you’re already subscribed to Claude Pro or Cursor, you can use those plans directly without extra costs.<p>Claudable runs entirely locally through Claude Code (Cursor CLI also supported) and provides:<p>- Instant UI preview (similar to Lovable)<p>- Web-optimized, production-ready designs<p>- Direct Git integration<p>- One-click Vercel deployment<p>- Zero additional API costs<p>It’s open source and available today.
