MrLesk/Backlog.md — reverse-engineered prompt

Build me a simple tool called Backlog.md that turns any project folder, especially a git repo, into a local task board using plain Markdown files. I want each task stored as its own readable Markdown file, and I want a zero setup command line experience where I can initialize a project, create and edit tasks, list and filter them, search across tasks and notes, archive things, and see an instant Kanban board right in the terminal.

I also want a clean browser view for the same data, with a responsive board, drag and drop columns, rich task forms, acceptance criteria checklists, and changes syncing back to the Markdown files automatically. It should stay private and work fully offline.

Please make it friendly for AI coding workflows too. After setup, an agent should be able to read project instructions and help break work into small tasks with clear acceptance criteria. It would be great if initialization can optionally set up AI tool integration, but also work fine as a normal standalone task manager. Look up current docs online if you need to.
