Prithvi Rajasekaran

Member of anthropic’s Labs team and author of Harness design for long-running application development (Mar 24, 2026). Worked on “two interconnected problems: getting Claude to produce high-quality frontend designs, and getting it to build complete applications without human intervention.”

Designed the GAN-inspired generator evaluator loop: a generator/evaluator pair for frontend design, extended to a three-agent planner–generator–evaluator harness for multi-hour autonomous full-stack builds, with sprint contracts negotiated between agents before any code is written.
