What was done
Replit's Agent 3 runs autonomously for up to 200 minutes, handling full application development from a single natural language prompt — building, testing, and fixing code with minimal human oversight. It includes a 'Stacks' feature that lets you create other specialized AI agents like Telegram bots or Slack integrations. One user went from a simple prompt to a fully functional Flask app with interactive map and Wikipedia integration in 10 minutes. The agent tests its own code in a browser reflection loop.
