Anthropic's engineering and product heads explain how Claude is used to build Claude

Overview

AISummary of 3 articles

Latent Space interviews Anthropic's heads of engineering and product, Katelyn Lesse and Angela Jiang, on how Claude Opus 5.5 was launched and built.

The interview covers Managed Agents, which keep the session log and harness separate from the sandbox that runs code, so a failed sandbox does not end the agent session and credentials can stay out of generated code's reach.

A Latent Space post says Claude is used to build Anthropic's first-party tools Code, Tag, and Duet, and that more than 50% of Anthropic's top customers use the platform. The post is promotional, and the report does not verify these figures.
