Anthropic breaks down the patterns behind successful Claude Code rollouts in monorepos, legacy systems, and codebases spanning thousands of developers, arguing that Claude Code performs agentic search over a live filesystem instead of relying on a RAG index that drifts out of sync with active engineering teams.
How you configure Claude matters more than the model itself. CLAUDE.md files, hooks, skills, plugins, MCP servers, LSP integrations, and subagents all load context in different ways. Teams that combine them with intent, instead of dumping everything into CLAUDE.md, navigate large codebases much better.
