Using Claude Code Effectively in Large Codebases: Best Practices and Where to Start

在大型代码库中高效运用Claude Code：最佳实践与入门指南

Claude Code is used in million-line monorepos, legacy systems, and distributed architectures, and the post says its large-codebase workflow relies on five extension points: CLAUDE.md, hooks, skills, plugins, and MCP servers for agentic search on local codebases.

Why it matters: HKR-H/K/R pass: official Claude Code guidance, five concrete extension points, and a direct coding-agent workflow nerve. It is a high-quality tutorial, not a new model or major capability release, so it stays in the 72–77 band.
