Katelyn Lesse and Angela Jiang lead the team building Anthropic's developer platform - the layer that both outside builders and Anthropic's own products run on top of. Angela frames the platform as a three-layer stack: knowledge, execution, and coordinatio...

Highlights

Anthropic's platform leads, Katelyn Lesse and Angela Jiang, discuss their strategy for building a developer platform that supports both external builders and internal product teams. They outline a three-layer stack of knowledge, execution, and coordination, emphasizing that the real leverage lies in the top coordination layer, where meta-harnesses assign different roles to tokens. The conversation covers their philosophy on open ecosystems, the importance of standards like MCP, and their approach to model routing.

Angela Jiang: The last layer of abstraction on top of this is probably the coordination layer. So you have knowledge and you have execution, and you have coordination. And at the coordination layer, we're beginning to think of these things called like stra...
