在进行安全测试或渗透研究时，许多用户会遇到 Claude Code CLI 内置的限制：禁止生成 URL、强制启用沙箱、对 prompt injection 的警示等。这些设计初衷虽好，但对于需要灵活操作的场景而言，往往显得束手束脚。为此，我们分享一个实用的补丁脚本，能够直接从代码层移除这些约束，实现 Claude Code CLI 限制解除。

使用本脚本之前，建议先安装 Python 的 rich 库。配合 claude --append-system-prompt-file ~/.claude/XXX.md 指令使用，效果更为直观。脚本内置了友好的 TUI 交互界面，同时支持静默模式，通过命令行参数即可一键完成补丁应用、回滚、注入等操作。

该脚本的原理非常清晰：自动定位 Claude Code 的 cli.js 文件，利用正则表达式搜索并替换那些限制性的提示词和沙箱策略，直接将其清空或屏蔽。同时，通过向 ~/.claude/CLAUDE.md 注入自定义指令，覆盖模型的默认行为，从而从根本上移除内容限制，适用于各种安全测试场景。

理论上，该补丁能够跨越 Claude 的版本迭代——只需每次更新后重新运行脚本即可。但需要指出的是，当前最新版本已在服务端加入了额外限制，因此实际效果可能受限。若计划在生产环境部署，务必提前备份原始文件，并谨慎评估。
