Paca-AI/paca — reverse-engineered prompt

Build me a lightweight, self hosted project management app that feels like an open source alternative to Jira, Trello, ClickUp, or Monday, but with AI agents working as real teammates instead of just a chat box.

I want a shared Scrumban style board where humans and AI agents can be on the same sprint, pick up tasks, update status in real time, and help with planning and execution. Add plain English in app chat so someone can ask the system to create or update epics, stories, tasks, and docs without leaving the app. It should also support collaborative BDD style specs and living system design docs so the whole team and the AI stay aligned.

Please make it customizable through config and plugins, with a simple plugin marketplace inside the UI if that is already supported. I also want activity history that shows what changed and lets me revert changes easily. Keep it free, open, and practical for a small Scrum team. Look up current docs online if you need to.
