Project mention: Show the Evidence That an AI Action Approval Actually Covered | dev.to | 2026-07-23
For a design critique, I would capture a fixed version of https://github.com/chaitin/MonkeyCode and use its visible workflows only as material for testing whether reviewers understand action, destination, and authority. That is a research prompt, not a representation that the repository supports the approval card above. Researchers who want feedback on their study framing can discuss it with users at https://discord.gg/2pPmuyr4pP without sharing participant data.

UnrealClaude
Claude Code CLI integration for Unreal Engine 5.7 - Get AI coding assistance with built-in UE5.7 documentation context directly in the editor.
You see the problem is, inside Unreal Engine everything is serialized binary data, stored as a .uasset file. So when I fire up Claude Code to have him review my blueprints, he can't. I search all over the internet, scouring in shock and dismay that somehow this is not a well solved problem. How is it even possible there isn't a full solution for this already, that an LLM can understand what's inside a .uasset? Admirable folks had begun putting up the foundations, but the gap was still very real. I started with the UnrealClaude plugin https://github.com/Natfii/UnrealClaude as the base (shoutout to Natfii, he created a lot of the base capabilities I built on top of, could not have done it without him). It has capability to create blueprints, but limited capability to parse existing ones as an exposed operation. So I leverage existing code in the plugin, and extend it so it can read blueprints in Unreal. And after that — aha! One of the boxes in one of the nodes was 1 when it should have been 10, Claude caught it first try once he could see it. Roadblock removed, I am back on track!

Project mention: Solving Backend Distributed Challenges in AI Programming Workbenches with Orleans | dev.to | 2026-06-21These ideas didn't materialize out of thin air. The solution shared in this article comes from our real-world battle scars in the HagiCode project. HagiCode is a desktop workbench for AI-assisted collaborative programming. Its backend coordinates dozens of AI CLI tools in a single process while providing low-latency real-time responses to the frontend—basically, we want the horse to run, not eat grass, and sing while running.

ai-intent-driven-development
AI Intent Driven Development (IDD) guidelines and instructions for AI Coding Agents, AI Coding Assistants, and LLMs.
I am working on a repository for AI Intent Driven Development at https://github.com/Exadra37/ai-intent-driven-development/.
An Intent is a self-contained document that describes a user request. It is composed of three main sections: WHY (the motivation), WHAT (the requirements, often in Gherkin language), and HOW (a detailed, step-by-step implementation plan defined with tasks). This approach ensures clarity and alignment before any code is written.
