Manus Skills VS ShellNewHandler

• Autonomous Agent Capability
  Manus Skills enables a highly autonomous AI agent that can independently perform complex tasks such as coding, research, data analysis, and web browsing without requiring constant human intervention, allowing users to delegate entire workflows.
• Extensible Skill-Based Architecture
  The skills-based design allows Manus to be modular and extensible, with different capabilities (like code execution, browser use, file management) organized as discrete skills that can be combined and chained together for complex multi-step tasks.
• Real-World Task Execution
  Unlike many AI assistants that only generate text responses, Manus Skills allows the agent to actually execute tasks in sandboxed environments — writing and running code, browsing the web, creating files, and delivering tangible outputs like reports, spreadsheets, or applications.
• Multi-Tool Integration
  Manus can seamlessly integrate and switch between multiple tools and environments (browser, terminal, code editor, file system) within a single task, enabling sophisticated workflows that would otherwise require a user to manually coordinate between different applications.
• User-Friendly Delegation
  Users can describe tasks in natural language and Manus handles the planning, execution, and delivery, making powerful computing capabilities accessible to non-technical users who may not know how to code or use specialized tools themselves.

Possible disadvantages

• Limited Transparency and Debugging
  As an autonomous agent that chains multiple skills together, it can be difficult for users to understand exactly what steps Manus is taking, making it hard to debug when something goes wrong or to verify the correctness of intermediate steps.
• Potential for Compounding Errors
  When executing multi-step autonomous workflows, errors in early steps can cascade and compound through subsequent steps. Without human checkpoints, the agent may go far down a wrong path before the user sees the final (incorrect) output.
• Closed and Proprietary System
  Manus is a proprietary platform, meaning users have limited ability to inspect, customize, or self-host the underlying system. This creates vendor lock-in and dependency on the company's continued operation, pricing decisions, and development priorities.
• Security and Privacy Concerns
  Giving an autonomous agent the ability to browse the web, execute code, and handle files raises security and privacy concerns, especially when tasks involve sensitive data. Users must trust that the sandboxed environment and data handling practices are sufficiently robust.
• Limited Access and Scalability
  Manus has faced availability constraints with limited invitations and access slots, making it difficult for many users to try or rely on the platform consistently. This limited availability can hinder adoption and makes it unreliable as a daily productivity tool for broader audiences.

• 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
