An agent marketplace makes agents shareable as units, not as code repos. Publish a YAML, a teammate runs digitorn install hub://you/my-agent, they have it. The Digitorn Hub is exactly this. The shape of an agent (one config file plus assets) is what makes the marketplace possible: you cannot package a LangChain Python class hierarchy the same way.
Engineering notes from the Digitorn team. No marketing, no launch announcements, no "10 prompts that will change your life". Just the things we write that we'd want to read.
