 "title": "Explain complex code in an unfamiliar project",
 "page_title": "How to explain complex code in an unfamiliar project with Claude Code",
 "summary": "Ask Claude Code in your terminal to explain how a part of an unfamiliar codebase works.",
 "who": "A developer who has just joined a team and must understand a large existing project before changing it.",
 "problem": "Reading unfamiliar code file by file is slow, and the parts that matter are often spread across many files.",
 "outcome": "A plain-language explanation of the chosen module, its main flow, and the files involved, so the developer can start work sooner.",
 "steps": [
  "Install Claude Code with one of the README methods, for example `curl -fsSL https://claude.ai/install.sh | bash` on macOS or Linux.",
  "Navigate to your project directory.",
  "Run `claude`.",
  "Ask in natural language to explain how a named module or feature works, and to list the files it depends on.",
  "Ask follow-up questions about any part that is still unclear."
 ],
 "agent_prompt": "Use Claude Code in the anthropics/claude-code-style workflow: open the project at <project-path> in the terminal, run `claude`, and ask it to explain how <module-or-feature> works, including the files it depends on. Expected output: a short written explanation naming those files. Verify by opening one named file and confirming the described function or flow appears there.",
