Boris Cherny Glossary
Boris Cherny is an Anthropic engineer best known in the Dictionary context for his association with Claude Code and for describing a style of work in which many coding agents are run in parallel, including overnight. His public comments are useful because they make visible a practice that otherwise sounds like science fiction: software work becoming orchestration of swarms of bounded agents rather than one human typing every line.
For the Dictionary, Cherny belongs near the entries on agentic coding, earned parallelism, and durable workflow because his work illustrates a change in the engineering role. The engineer increasingly manages experiments, diffs, tests, branches, and review queues rather than writing every line directly.
That shift is powerful, but only when the surrounding workflow can absorb the parallelism. Otherwise the agents merely create more things to inspect badly.
