How Anthropic teams use Claude Code

• The teams that built Claude Code use it the same way power users do — for real engineering tasks with the same agentic patterns they're shipping to customers
• Internal workflows rely heavily on CLAUDE.md files tuned per codebase, multi-agent runs for complex refactors, and hooks that enforce code standards automatically without prompting every session
• The core mental model from Anthropic: onboard Claude like a new developer — give it explicit project context, coding conventions, and known pitfalls rather than assuming it knows your codebase
• This is the ground-truth signal on how Anthropic intends Claude Code to be used, straight from the teams that ship it
