CAT: Making AI Coding Agents Reliable

Keep your AI coding agent from randomly ignoring your team’s hard-earned rules. CAT solves the annoying problem where an agent follows a convention in one file but forgets it in the next. Instead of hoping the model behaves, this tool tests your project rules until they are proven to work ninety-five percent of the time. It then hands those reliable instructions directly to coding tools like Claude Code, ensuring your agent actually follows them. If a reviewer finds a gap, you simply add the new lesson to your shared rulebook.

Chums: Your Coding Agents on Your Wrist

Chums is the Apple Watch app that turns your existing coding agents into animated characters on your wrist. It connects the Claude Code and Codex tools already running on your Mac to your watch and iPhone, letting you talk to them hands-free. The most striking part is how each agent acts out its work. You hold the screen to speak, and the character visually shifts through states like listening, thinking, or working. This gives you real-time feedback without opening a laptop. It is free, open-source, and runs entirely on your own hardware. No new subscriptions are required.

Deltabox Lite: The Undo Button for AI Agents

Deltabox Lite is the sandbox tool that gives AI coding agents a safety net by treating every file change like a reversible draft. Instead of letting an automated program mess up your project without a way back, this lightweight system wraps commands in a confined space where you can see exactly what changed. If the output looks wrong, you simply abort and your files snap back to how they were before, just like pressing undo. This solves the anxiety of running powerful, autonomous code by giving you total control over what actually sticks to your disk.

Co-op Anything: Make Any Game Multiplayer With AI

Your AI coding agent can now turn any single-player game into a co-op experience for you and your friends. The project, called Co-op Anything, acts as a detailed playbook that instructs your agent to research, reverse engineer, and fix existing mods or build new ones from scratch. It handles the complex technical work, including setting up networking so you can join a game over Steam without any port forwarding or extra purchases. The most interesting part is that it tests its work automatically using bots inside the actual game to ensure the co-op actually functions before you ever install it.

Run Kingdom Hearts 358/2 Days natively on your PC

Play Kingdom Hearts 358/2 Days natively on your PC with a project called khdays-port. This experimental runtime takes the game code from a full decompilation and runs it directly on modern hardware, bypassing the Nintendo DS entirely. It replaces the original console hardware with new graphics, sound, and input layers, letting you enjoy the game at higher resolutions with modern controller support. The engine handles rendering and audio independently, so you get a crisp, high-definition experience without the original system limits. If you are curious about how game preservation works, this is a fascinating look at rebuilding a classic title from the ground up for today's machines.

Better Claude: Queue Tasks Like a Pro

Better Claude solves a frustrating problem in terminal based coding: the mess that happens when you type new instructions while the AI is still working on the first one. Usually, that new text gets injected immediately and changes the AI's current plan, causing it to mix up priorities and get confused. This project fixes that by letting you type a command called After to queue up tasks for later. You can keep typing while the AI works, and your new instructions wait safely in the background. When the current job finishes, the next task runs automatically.

Zena: The TypeScript That Compiles to WebAssembly

Zena is a programming language that writes itself mostly through AI to compile into high-speed WebAssembly code. It borrows the familiar syntax of TypeScript but swaps out JavaScript’s loose rules for strict, predictable logic inspired by languages like Swift and Rust. The real surprise is that it runs directly on the new WebAssembly garbage collection standard, meaning your code compiles to tiny, efficient binaries without needing a bulky runtime. It also features a clever ownership system that handles memory cleanup automatically at compile time, preventing crashes before you even run your program.

Textus: The AI Markdown Editor

Edit Markdown that renders itself as you type, then let an AI assistant draft your next sentence right in the editor. Textus is a free, open-source writing app for macOS, Windows, and Linux that blends a clean document editor with a smart writing partner. The standout feature is how the AI proposes edits as gentle suggestions rather than overwriting your work, so you stay in control while it fixes typos or tightens your prose. It also remembers your personal writing style to keep the voice consistent. If you want a distraction-free space where technology handles the mechanics so you can focus on the message, give Textus a try.

OpenGCUA: The AI That Writes Code to Use Your Computer

OpenGCUA is the open-source stack that lets AI agents write code to actually use your computer. Instead of just clicking buttons like a slow human, it runs real programs to handle apps, phones, and browsers all at once. It works by letting the AI decide exactly what to look at and how to act, often using loops and checks to finish jobs faster than traditional bots. This creates a smarter assistant that can share your screen without interrupting you. It is a major step toward AI that works alongside you on real devices, making automation more flexible and efficient.

Django DevBar: Spot Database Slowdowns

Django DevBar flags duplicate and similar database queries right on your screen, saving you from performance traps. Instead of guessing why a page feels slow, it shows exactly how many queries ran and how long they took. The tool sends this data through standard response headers, meaning it works even on plain API endpoints that return just text or JSON. You can view the stats in a lightweight bar on the page, or open a dedicated browser extension panel in your developer tools for a detailed breakdown. It helps you catch inefficient loops and redundant lookups before your app slows down under real traffic.
