MKlolbullen/termaid ? reverse-engineered prompt

Build me a terminal app for bug bounty workflow automation that feels polished and easy to use.

I want to be able to open it in the terminal, pick a target domain, and build a recon or scanning pipeline by connecting tools into a simple visual workflow. It should use Mermaid style charts for the workflow, let me preview the diagram, save and load workflows, and run them against a domain with live status updates as each step finishes.

Please include a built in list of common bug bounty tools with sensible defaults, support running workflows from a JSON file or a Mermaid file, and make it easy to run everything from the command line too, not just the interactive screen. It should also handle passing output from one step into the next, avoid duplicate results, and let me change arguments for each tool. If you need to check current docs or examples online, go ahead.
