What is the problem?
给 AI 工具新手看的网页修改工具选择指南：什么时候用 Claude Code，什么时候用 Codex，如何判断任务范围、验证结果和交付风险。
Quick solution
Treat this as a Codex tutorial issue. First confirm the environment, inputs, permissions, logs, and delivery boundary. Then use the linked deep guide for the full checklist before changing production code or promising a result.
Read the deep guideDetailed steps
- 先判断任务类型：文案、样式、组件、路由、表单、构建错误还是部署问题。
- 判断上下文需求：是否需要完整仓库、设计稿、截图、浏览器复现步骤或客户说明。
- 如果需要跨文件修改和命令验证，优先用 Codex 在仓库里操作。
- 如果只是解释片段、生成方案、列风险点，可以用 Claude Code 辅助思考。
- 修改前保存当前状态，确认 `git status` 没有你不理解的变更。
- 修改后跑对应检查，例如 `npm run lint`、`npm run build`、页面截图或手动验收。
Commands or code
The source article does not include a copyable command block. Do not invent commands here; follow the diagnostic steps in the deep guide and validate changes in the real project environment.
Risk notes
Confirm the real project environment, account permissions, platform rules, and output quality before delivery. Do not ship AI-generated changes without human review, and do not claim indexing, income, deployment success, or ranking improvements without measured evidence.
