context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
Why it matters
A rare inside look at how Anthropic's own Claude Code team structures AI-native engineering — code review at 8x throughput, Claude 'routines' for managing output, and the context windowThe maximum amount of text a model can consider at once — its working memory for the current conversation or task.Full definition →-switching bottleneck no one has solved — useful for teams reorganizing around coding agents.
Key quotes
“Coding is no longer the bottleneck.
It's lifted the ceiling of what anyone is able to do.”
