[Testing] Show HN: RLM-based local debugger for AI agent traces We built HALO (Hierarchal Agent Loop Optimizer), an open-source tool for debugging and optimizing AI agents using their execution traces.<p>It’s a loop. Run your agent, feed the traces to HALO, get the report, apply the fixes, then re-run your agent.<p>HALO takes in OTEL compliant traces from AI agents using tracing frameworks such as Langfuse, Arize&#x2F;OpenInference, or even just plain JSONL. It uses an RLM (Recursive Language Model) to more efficiently break trace analysis into smaller subproblems in order to find recurring patterns across large amounts of data and fix systemic issues that regular LLMs might typically miss.<p>You can also optionally provide a path to where your agent code lives to give the engine more context so it can more concretely provide useful insights.<p>The repo also includes a desktop app that you can run locally without having to sign up for anything or configure anything complex.<p>Check out the readme in the repo for more in depth information on what HALO is and how you can use it to your benefit :)

[Other] Show HN: The Cascade Graph – An interactive map of AI and energy constraints Hello, I wanted to share with you all a interactive map of the economics and physics constraints of the AI buildout. It has macro drivers, industrial chokepoints, and where that shows up in markets.<p>I&#x27;ve added 393 nodes and 562 edges to capture other supply &#x2F; physics constraints as well.<p>There&#x27;s no sign up, and no pay wall, it&#x27;s all free.<p>Please let me know what you think!

Show HN: TikZ Editor – WYSIWYG editor for figures in LaTeX Hi all! TikZ is a widely-used LaTeX package for drawing figures in papers. It uses commands like \draw[-&gt;] (0,0) -- (1,2); to draw lines, shapes, text, etc. Academics usually code up their figures by hand, so there is lots of twiddling around with the coordinates and recompiling until things look nice. I guess it’s a bit like SVG, but it’s more code than markup, for example it has loops with \foreach.<p>I built an open-source WYSIWYG TikZ editor (available for web and desktop) that allows you to edit your TikZ source code visually by dragging and resizing elements. It simultaneously shows the source code and the rendered figure, and lets you edit either one while the two views stay in sync. I’m not aware of any other editors that are simultaneously source editors and WYSIWYG (even for editing SVG or HTML), and I’m quite pleased with how well the combination works.<p>The way the app is implemented is by parsing the TikZ code, and at all times keeping track of the exact source location of each object. Thereby, when a user drags an element to a new position, the app can override just the numbers in the coordinate without changing anything else in the code (such as line breaks or indentation).<p>This approach essentially required reimplementing a large fraction of TikZ, which is the kind of task that no human would ever want to do. I think building software that doesn’t exist yet because it would be impossibly tedious to code up is one of the great new possibilities thanks to coding agents, and it’s worth brainstorming for other examples. (This app was built almost entirely by Codex.)<p>Implementing the app came with lots of fun side quests, including building converters from SVG &#x2F; pptx &#x2F; ipe to TikZ, re-implementing the LaTeX hyphenation and line-breaking algorithm to support multi-line nodes, and making a color picker that uses the red!20!black color mixing notation used in LaTeX papers.

Show HN: Transformer Primitives – A visual explainer you can send to anyone I have had a few conversations in the past year with non-technical folks (traditional finance types, consultants) who asked for a simple explainer on how GPTs work. These people generally have the horsepower to grasp new concepts quickly but don&#x27;t necessarily have the math background to dig in super deeply and want a stronger framework than &quot;they predict words&quot;.<p>I had generally been pointing them to Karpathy, Illustrated Transformer, and other youtube content but I figured something more hands on without the math requirement might be better at explaining questions like &quot;why matrix multiplication?&quot;.<p>I built this as a simple 60-70 minute interactive course with some demos I could send along to them. I&#x27;ve found it effective as the initial foray into understanding jargon and concepts before they graduate to Karpathy et al.<p>It&#x27;s free, no signup required. I would love feedback on where it might lose a non-technical reader, and where someone who does this for a living thinks I have simplified past the point of being correct.<p>understandgpt.xyz

Show HN: Shumai – open-source Frame.io alternative for creative work Shumai is an open source platform for uploading creative files, managing projects, collecting precise feedback, sharing work, and collaborating with AI agents, all in one simple creative-first workspace.<p>I’ve always liked the product design of Frame.io, and I wanted to build an alternative that feels just as polished, while being open source and easy to self host.<p>You can deploy Shumai with docker compose in just a few minutes. It can also be installed from npm, though you&#x27;ll need to provide your own PostgreSQL instance with the pgvector extension installed.<p>For larger deployments, Shumai supports distributed processing via Temporal, allowing resource intensive tasks such as transcoding to be scaled independently.<p>It&#x27;s still early in development, feel free to try and share any feedback.<p>Demo: <a href="https:&#x2F;&#x2F;staging.shumai.one" rel="nofollow">https:&#x2F;&#x2F;staging.shumai.one</a>

Show HN: Neural Particle Automata Neural CAs model self-organizing pattern formation on grids. Now the grid is gone. Each cell is an agentic particle that can move freely in space and change its state.<p>While each particle follows a simple shared rule, many together can grow complex morphologies or form intricate patterns. The resulting particle system as a whole can regenerate from damage and exhibits surprising emergent behavior.<p>Try cutting the lizard and watch it heal itself!

Show HN: A pure ARM64 Assembly web server, now on Linux with CGI for no reason This is ymawky, a now-dynamic web server written entirely in ARM64 Assembly. I&#x27;ve previously posted about ymawky here: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=48080587">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=48080587</a><p>In the past month and a half, I&#x27;ve made some pretty major improvements: I&#x27;ve added CGI scripting support, so the server now supports query strings and dynamic content; and I&#x27;ve fully ported ymawky to run on Linux, rather than macOS-only.<p>In addition to GET&#x2F;PUT&#x2F;HEAD&#x2F;DELETE&#x2F;OPTIONS requests, because of CGI support ymawky also accepts POST requests (only to CGI resources for now).<p>I&#x27;ve also updated the more detailed writeup to reflect CGI support and the Linux port: <a href="https:&#x2F;&#x2F;imtomt.github.io&#x2F;ymawky&#x2F;" rel="nofollow">https:&#x2F;&#x2F;imtomt.github.io&#x2F;ymawky&#x2F;</a>
