Analysis

An editorial look at what each product does well and who it suits.

Agent Development Kit
ShellNewHandler

Overall verdict

  • Google's Agent Development Kit (ADK) is a solid, well-designed open-source framework for building, evaluating, and deploying AI agents, especially for developers already working within or alongside the Google Cloud and Gemini ecosystem.

Why this product is good

  • Open-source and code-first, giving developers fine-grained control over agent behavior, orchestration, and tooling
  • Strong integration with Google Cloud, Vertex AI, and Gemini models while still supporting other models via LiteLLM
  • Supports multi-agent architectures, allowing you to compose specialized agents into hierarchies for complex workflows
  • Includes built-in tools, streaming support, and a rich set of pre-built connectors and function-calling capabilities
  • Provides evaluation and debugging utilities plus a developer UI to test and inspect agent runs locally
  • Backed by Google with active documentation, examples, and a growing community

Recommended for

  • Developers building production-grade multi-agent systems
  • Teams already invested in Google Cloud, Vertex AI, or Gemini models
  • Engineers who prefer a code-first, flexible framework over no-code agent builders
  • Organizations needing robust evaluation, debugging, and deployment tooling for agents
  • Prototyping and experimenting with agentic workflows and tool integrations

Overall verdict

  • ShellNewHandler is a niche, lightweight utility hosted on SourceForge designed to give users more control over the Windows 'New' context menu (the ShellNew menu). It can be considered good for its specific narrow use case, but it is an older, minimally maintained tool that may not suit all users, especially those on modern Windows versions.

Why this product is good

  • Provides direct control over customizing the Windows right-click 'New' menu, allowing users to add or remove file type entries
  • Lightweight and free, without bundled bloatware typical of some other free utilities
  • Simple and focused in scope, making it easy to understand for its specific purpose
  • Open distribution via SourceForge allows transparency and no-cost access

Recommended for

  • Power users who want to declutter or customize the Windows New context menu
  • IT administrators managing standardized desktop environments across multiple machines
  • Users comfortable with older utility-style tools and Windows registry-related tweaks
  • Not recommended for casual users seeking modern, actively supported software with regular updates

  • What's the best AI agent platform?
    Model-provider SDKs. OpenAI's Agents SDK, Anthropic's SDK and Google's ADK sit one level below frameworks: tool use, structured output and loops, without opinions about orchestration. Thinnest layer, least lock-in, most code you write... - Source: dev.to / 3 days ago

  • I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?
    Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago
  • This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?
    I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
