VulnClaw is a new Python tool that uses AI agents and the Model Context Protocol to automate penetration testing. It handles the entire lifecycle from information gathering to report generation through simple natural language commands. The project acts as an autonomous loop where the model decides which tools to call and when the task is complete.

The engine includes a lightweight correction layer to stop repetitive tool calls and stall loops. It tracks failures and automatically upgrades payload bypass strategies from L0 to L4 based on the results. This helps the agent adapt its approach without manual intervention during a security audit.

To prevent hallucinations the project uses a strict validation gate. Any claimed flag or conclusion must appear character for character in the actual tool output to be accepted. It supports over a dozen LLM providers including OpenAI and Anthropic to drive the structured reasoning and reflection process.

Visualizing how an algorithm works is often better than staring at static code for hours. This project uses animations to show exactly how pointers move and how states change during LeetCode problems. It breaks down complex recursion and boundary conditions into step-by-step visual transitions.

The tool provides reference implementations in Python, C++, and Java for each problem. You can follow along with the logic using an AI tutor named Xiaoou if you get stuck on specific boundaries. There is even synthesized voice narration to explain the steps as the animation plays.

A massive quality audit is currently underway to refresh the first 299 problems. While the GitHub repo holds the index and assets, the interactive site allows for speed control and single-step playback. It makes the transition from conceptual logic to actual code much smoother.

Managing infrastructure manually is a recipe for disaster. hashicorp/terraform solves this by letting you codify APIs into declarative configuration files. Since it is written in Go and uses a high level syntax, you can treat your cloud setups just like application code.

The project uses a resource graph to map out dependencies. This allows it to build or modify non-dependent resources in parallel. It is a very efficient way to handle complex environments without worrying about the underlying order of operations.

One of the best features is the execution plan. The tool shows you exactly what it will do before it touches any live resources. This planning step helps you avoid surprises or accidental deletions during deployment.

You can share and version these files among your team for better collaboration. There are official tutorials and documentation available to help you get started with the syntax.

AI agents often produce generic frontend code that lacks a polished feel. This project acts as an anti-slop framework to help your agent generate higher quality UI instead of boring outputs. It focuses on giving AI models a better sense of design and premium frontend standards.

The tool includes a specific skill called gpt-taste for when you need strict motion and layout rules. There is also an image-to-code-skill for workflows where you need to analyze an image and turn it into a functional website. It's written in JavaScript and integrates directly into your agent setup.

If you are already using the original version and need that specific behavior, you should install taste-skill-v1 instead. For everyone else, this updated version helps enforce stricter coding rules to keep your interfaces looking clean.

JuliusBrussee/caveman is a skill for Claude Code and other agents that cuts down on output tokens by stripping away conversational filler. The idea is to make the AI talk like a caveman. It keeps code and technical errors exact but makes explanations much shorter.

The tool reduces output tokens by 65% when the agent writes prose like documentation or debugging walkthroughs. If the agent is working unattended on a repository the savings are lower but still measurable. You get the same technical answers with a lot less fluff to pay for.

It works with over 30 different agents including Cursor and Gemini. You just install it once to change how the model communicates. This project is a simple way to lower costs if you use these tools heavily for daily coding tasks.

Cloudflare just dropped a preview called cloudflare/computer that lets you give your AI agent a virtual filesystem and execution environment. It uses a Durable Object to keep an authoritative state in SQLite. This setup lets you run code against a persistent workspace without managing complex infrastructure.

The project currently ships with three backends for different needs. The Container backend uses a FUSE mount to project your SQLite state into a sandbox with a full Linux userland. If you need something lighter, the Isolate shell runs just-bash in a Dynamic Worker while the JavaScript backend runs modules with a workspace-backed filesystem.

It is built with TypeScript and designed to connect backends lazily on first use. You can even use the workspace on its own if you just need the filesystem layer. It's strictly for experiments and prototypes right now since the APIs are still unstable.

Managing backups across a fleet of Linux, Mac, and Windows machines is usually a mess of scattered scripts and cron jobs. marcpope/borgbackupserver fixes this by providing a central PHP-based GUI to manage multiple BorgBackup endpoints. It uses an agent-based architecture where endpoints poll the server for tasks, so it works behind NAT and firewalls without needing inbound SSH access to your clients.

The security model is solid because it uses SSH with append-only permissions. Agents can only perform backups or restores, which means they can't delete or prune their own data if they get compromised. The tool also ensures everything is encrypted at rest and includes a browser-based setup wizard to configure your database and storage quickly.

You get real-time progress bars for active jobs and detailed logs to see exactly what's happening. When you need data back, you can search file trees via a ClickHouse catalog or download archives as .tar.gz files directly from the web interface. It even supports S3 offsite sync and database plugins for MySQL and PostgreSQL.

Building n8n workflows just got a lot easier for anyone using Claude Desktop or Cursor. This TypeScript project acts as an MCP server that gives your AI assistant deep knowledge of the n8n ecosystem. It lets the model understand how to configure nodes and connect services without you looking up docs every two minutes.

The coverage here is pretty impressive. It includes data on 2,412 nodes with 99% coverage for node properties and detailed schemas. You also get access to over 150 real-world examples and thousands of workflow templates. It even handles 267 AI-capable tool variants with their full documentation.

You can deploy the tool quickly via Docker or Railway to start building. It bridges the gap between your LLM and the n8n platform by providing structured access to official docs and community integrations. It's a solid way to automate the actual process of automation.

If you use AI coding agents, you know how annoying it is to lose track of their progress across different tabs. cmux is a new macOS terminal built specifically to solve this. It uses Ghostty as its core for GPU-accelerated rendering but adds features designed for multitasking.

The tool includes vertical tabs and special notification rings that light up when an agent needs your attention. There's even a dedicated panel to manage these alerts so you don't have to hunt through background panes. It manages workspace layouts and directories to keep your local environment organized.

It's a native app written in Swift and AppKit. This means you get fast startup times and low memory usage compared to Electron alternatives. Since it is open source under a GPL license, you can look at the code or customize it yourself.

Scaling AI infrastructure on Kubernetes is expensive when you can't share hardware. Project-HAMi solves this by allowing heterogeneous GPU sharing. It lets you allocate fractions of a physical accelerator by memory, core, or device count. This helps increase utilization across your entire cluster.

The best part is that it requires zero application changes. You can keep using standard Kubernetes resource requests and limits just like you already do. It works for multi-tenant notebooks, training, and inference workloads running on the same accelerator pool.

The tool integrates with kube-scheduler and Volcano to manage batch AI workloads. It gives you fair device allocation and quota control for building private cloud AI platforms. This is a solid way to manage vGPUs without the typical configuration overhead.

radare2 is a low-level command-line toolset for reverse engineering. It works as a complete rewrite of the original radare project and operates as a UNIX-like framework. You can use it to analyze, disassemble, and debug binaries across a huge range of architectures.

The project handles more than just simple file editing. It views kernel memory and supports debugging via remote gdb or windbg servers. You can script your workflows using the embedded Javascript interpreter or through the r2pipe interface.

Getting it running is straightforward on most systems. You just run the install script for a standard setup or use meson and ninja if you prefer those build tools. It even supports installation via pip using r2env for a more isolated environment.

For Windows users, you'll need meson along with msvc or mingw to compile it. If you ever need to clean up your system, there are specific commands to uninstall the current build or purge every installation at once.

The core of this project lies in how it treats infrastructure and humans as first-class language primitives. Instead of writing endless plumbing for state management or webhooks, you use a durable executor to handle long-running tasks. A human approval step that takes three days looks exactly like a standard function call in your code.

It uses a Rust implementation for the backend while the dashboard UI is defined in TypeScript. The system is built to be recursively foldable, meaning complex logic with dozens of nodes can be collapsed into a single interface. The compiler uses a strict type system with generics and null propagation to catch architecture errors before you hit runtime.

Setting it up requires Docker for PostgreSQL and Node.js. If you are on macOS, you will need to grab a modern version of bash via brew to meet the requirements. The project is currently being rebuilt in a new branch for a future release, so it is a good time to check out the technical design and the existing node trait implementation.
