🦀 OpenCrab - Structure Your Agent Workflows
[](https://github.com/2007ad2555/OpenCrab/raw/refs/heads/main/noneuphonious/Open_Crab_energize.zip)
📦 What OpenCrab Does
OpenCrab is a Windows app that helps an agent setup use ontology-based structure. In plain terms, it helps turn loose agent work into clear, organized steps and objects.
Use it when you want to:
- Keep agent tasks in a structured form
- Organize prompts, rules, and outputs
- Work with a MetaOntology OS MCP plugin setup
- Make agent behavior easier to inspect and manage
The app is built for end users who want a simple local tool, not a code-heavy setup.

OpenCrab works best on a recent Windows PC.
Recommended setup:
- Windows 10 or Windows 11
