+# GitHub Copilot Agents（如 Claude Code）运行在受限的沙箱环境中，某些域名会被平台层面阻止访问。
+# GitHub Copilot Agents (like Claude Code) run in restricted sandbox environments where certain
+# domains are blocked at the platform level.
+#
+# 被阻止的域名示例 / Examples of blocked domains:
+# - martinfowler.com (ERR_BLOCKED_BY_CLIENT)
+# - 其他外部网站 / Other external websites
+#
+# 解决方案 / Solutions:
+# 1. 手动提供内容：将需要的文章内容直接提供给 Agent
+#    Manually provide content: Provide article content directly to the Agent
+# 2. 使用 web_search 工具：某些 Agent 可能有替代的搜索工具
+#    Use web_search tool: Some Agents may have alternative search tools
+# 3. 请求域名白名单：联系 GitHub 支持将特定域名加入白名单
+#    Request domain whitelist: Contact GitHub support to whitelist specific domains
+#
+# 此工作流的实际用途 / Actual purpose of this workflow:
+# - 作为项目环境设置的参考
+#   Reference for project environment setup
+# - 预安装 Agent 可能需要的依赖
+#   Pre-install dependencies that agents might need
