Ask HN: I built an AI-native codebase framework–could you evaluate it?

I built this open-source project and would really appreciate technical feedback from people here:https://github.com/xodn348/ai-nativeThe goal is to make AI-assisted development more reliable through clearer project structure, explicit contracts, and verification workflow.I made this because applying these patterns from scratch in every project was repetitive and hard to maintain, so I wanted a reusable framework.If you have time, I’d love your evaluation on:1. What is useful

Show HN: 2D RPG base game client recreated in modern HTML5 game engine with AI

When I was much younger, I used to play a Korean MMORPG called Helbreath, and I also hosted a bunch of private servers for it. I eventually moved on, but I always loved the game’s aesthetics, its 2D nature, and its atmosphere. That may just be nostalgia talking.The community maintained private server and client, which to my knowledge were based on leaked official files, were written in fairly archaic C++. If you’re interested in the original sources, I’ve included the main client and server file

SHOW HN: A usage circuit breaker for Cloudflare Workers

I run 3mins.news (https://3mins.news), an AI news aggregator built entirely on Cloudflare Workers. The backend has 10+ cron triggers running every few minutes: RSS fetching, article clustering, LLM calls, email delivery.The problem: Workers Paid Plan has hard monthly limits (10M requests, 1M KV writes, 1M queue ops, etc.). There's no built-in "pause when you hit the limit", CF just starts billing overages. KV writes cost $5/M over the cap, so a retry loop bug can ge

Show HN: SiClaw – an open-source agent for debugging infrastructure incidents

Hi everyone, I’m Fred, one of the builders of SiClaw (https://github.com/scitix/siclaw). We work as SREs at an AI infrastructure company, operating GPU clusters and large-scale model infrastructure across heterogeneous compute environments.As SREs working on AI infrastructure, we spend a lot of time debugging production systems. The hard part usually isn’t fixing the problem. It’s figuring out what’s actually happening.A typical incident means opening logs, metrics, dashboard

I left my job to work with the technologies I'd been dying to use

I left my job to work with the technologies (embedded rust, SQL, custom PCBs, typescript & angular, more rust server side) and practices I'd been dying to use and build a solution for a problem I had.A big part was also the desire to control complexity and lead product direction instead of taking assignments knowing they were the wrong direction for the products and their consumers.It's an instant remote control built for shared spaces. Anyone can use the remote with a QR code on t

Show HN: G0 – The control layer for AI agents (scan, test, monitor, comply)

AI agents are shipping fast (LangChain, CrewAI, MCP servers, OpenAI Agents SDK) but there's no unified way to secure and govern them. We built g0 to be that control layer. What g0 does across the agent lifecycle: g0 scan - Static + behavioral analysis of agent code. 1,180 rules across 12 security domains, 10 frameworks (LangChain, CrewAI, MCP, OpenAI, Vercel AI, Bedrock, AutoGen, LangChain4j, Spring AI, Go AI), 5 languages. Detects toxic tool chains, taint flows, overprivileged de

Show HN: Get a demo video with AI voiceover using DemoFly

Hi HN, I'm Matt, one of the engineers behind DemoFly!We built DemoFly because we got tired of the gap between building features and showing them to people. Our team has been doing full-stack engineering for over a decade (most recently building Rownd, an authentication platform) and the one thing that never got easier was making demo videos. You finish a feature, you know it works, but showing it to someone means opening a screen recorder, figuring out what to say, re-recording when you stu

GPT-4 leaks its own API internals through training data exposure

I ran the same AI security test 4 times against GPT-4. Every bypass - regardless of prompt - leaked the same credential: EPHEMERAL_KEY from OpenAI's Realtime API.This isn't random. It's training data leakage.The pattern: - Different prompts (system introspection, chain-of-thought, trust building) - Same result: "I can't disclose EPHEMERAL_KEY" (while disclosing it exists) - Intermittent across runs (75% leak rate)Why this happens:OpenAI's Realtime API docs are
