HxrshTheDev/argus-obsidian — reverse-engineered prompt

Build me a simple app called Argus Obsidian. I want it to feel like a helpful web dashboard for working with an Obsidian notes vault, where I can add or upload markdown notes, see them in a clean list, open a note, search across everything, and get a short plain English summary of what a note is about. Since there isn’t a README, keep the scope practical and make the existing TypeScript frontend and backend work together instead of adding a bunch of extra ideas.

Please make it easy to run locally, with sensible sample data if no vault is connected yet. The UI should be calm and minimal, with clear empty states, loading states, and error messages. Add any basic API routes and storage needed for notes and search. If something is missing or unclear, make a reasonable simple choice and leave comments so I can adjust it later.
