technowizard/devcache — reverse-engineered prompt

Build me DevCache, a polished developer knowledge hub where I can save and quickly find code snippets, useful links, files, notes, and prompts.

I want users to be able to sign up or log in with GitHub or email, then manage a personal dashboard with collections, custom item types, tags, favorites, and pinned items. Snippets should have a nice built in code editor with syntax highlighting. Files like images and PDFs should be uploadable when storage is configured. Make it feel clean and modern with a great dark mode.

Include the basics for a public landing page, auth screens, dashboard, item search and filtering, settings, and sensible empty states. Add support for optional AI features through OpenRouter, optional Pro subscriptions through Stripe, and rate limiting when Redis is configured, but keep the app usable locally without those optional services.

Use the existing TypeScript Next app setup, Prisma and PostgreSQL. Please wire up the database models, API routes, UI, and tests where it makes sense. Look up current docs online if needed.
