Agent Composer – Create your own AI rocket scientist agent

Hacker News

Hey HN! We launched a thing today, and built a cool demo that I'm excited to share with the community. This tool creates AI agents easily and can handle some really technically complex work. I whipped up this rocket scientist agent in our tool in 10 minutes. I asked a couple of aerospace engineer friends what they thought, and they found it useful for their real work, which is why I want to share it here. Here's the demo https://demo.contextual.ai/ and an overview https://docs.contextual.ai/examples/rocket_science Would love to see technical HN folks and their experience with our tool (and whether it would be useful in your work). Happy to go deep on architecture, retrieval strategies, and lessons learned.
