    Claude Code 最佳实践指南

    Anthropic 发布 Claude Code 最佳实践指南,核心约束是上下文窗口会快速填满且性能随填充下降。指南建议先给 Claude 可运行的验证方式(测试、构建、截图对比),并按探索、规划、实现、提交四阶段工作流推进,配合 plan mode 分离研究与执行。

If you use GitHub, install the gh CLI. Claude knows how to use it for creating issues, opening pull requests, and reading comments. Without gh , Claude can still use the GitHub API, but unauthenticated requests often hit rate limits. Claude is also effective at learning CLI tools it doesn’t already know.

    如何在 CI 中用 LLM 评测门禁 Pull Request

    安全研究者 Johann Rehberger 在 BlueHat Asia 2026 披露 SQL Server Management Studio 中 Copilot 的提权漏洞 CVE-2026-65669,该漏洞被微软评为严重级别。研究发现 Copilot 的只读模式仅靠 LocalSqlExecutionAccessChecker 中的正则黑名单实现,通过 DECLARE @p sysname='sp_who'; EXEC @p 或 sp_executesql 即可绕过,进而执行 CREATE、INSERT、UPDATE、DELETE、DROP 等任意 T/SQL。攻击者还可利用数据库元数据中的 AGENTS.md 与 CONSTITUTION.md 指令实施间接提示词注入,在低权限用户植入指令后由高权限用户的 Copilot 执行,最终把 db_owner 加入 sysadmin 角色;作者建议只读约束应作为安全不变量而非模型指令。

PyTorch doesn’t use GitHub’s merge button that means PRs are closed, then PyTorchBot squash-merges and applies a “Merged” label. So detecting a landed PR requires checking for that label: Edge case: A race condition can cause the label to be applied after the dispatch, or a manual merge may skip the label entirely.
