Scaling Managed Agents: Decoupling the brain from the hands（Anthropic Engineering）
中文摘要：Anthropic 工程博客深入介绍 Managed Agents 架构设计哲学，核心思路是"解耦大脑与双手"——将代理的会话（session）、 harness（调用循环）和沙箱（sandbox）抽象为独立接口，使各组件可独立演进和替换。该设计解决了早期单体容器架构的"宠物服务器"问题，将 harness 移出容器后，p50 首 token 延迟降低约 60%，p95 降低超 90%。通过将凭证与沙箱隔离、会话日志持久化存储在外部，系统实现了更好的安全性、可恢复性和扩展性，支持多大脑连接多双手的灵活部署模式。
English Summary: Anthropic's engineering blog details the Managed Agents architecture, centered on decoupling the "brain" (harness) from the "hands" (sandboxes) and session logs. By abstracting sessions, harnesses, and sandboxes into independent interfaces, each component can evolve and be replaced separately. This solved the "pet server" problem of the earlier monolithic container design. Moving the harness out of containers reduced p50 time-to-first-token latency by ~60% and p95 by over 90%.

Improving token efficiency in GitHub Agentic Workflows（GitHub AI/ML）
中文摘要：GitHub 工程团队分享了在生产环境中优化 Agentic Workflows 的实践经验。通过在 API 代理层统一采集 token 使用数据，团队发现未使用的 MCP 工具是主要开销来源——40 个工具的 JSON Schema 可能为每次请求增加 10-15KB 上下文。他们构建了每日 Token 审计与优化工作流，将数据获取操作从 LLM 推理循环中剥离，改用 GitHub CLI 预下载或代理方式执行。优化后，Auto-Triage Issues 工作流节省 62% 的 Effective Tokens，Security Guard 和 Smoke Claude 分别节省 43% 和 59%。文章还提出 ET（Effective Tokens）指标来标准化不同模型间的成本比较，并强调运行频率与单次节省同等重要。
English Summary: GitHub's engineering team shares practical experience optimizing Agentic Workflows in production. By instrumenting token usage at the API proxy layer, they identified unused MCP tools as a major cost driver—40 tools' JSON schemas could add 10-15KB per request. They built daily token auditing and optimization workflows, moving data-fetching operations out of the LLM reasoning loop using GitHub CLI pre-downloads or proxy approaches. Results show Auto-Triage Issues reduced Effective Tokens by 62%, while Security Guard and Smoke Claude achieved 43% and 59% savings respectively. The article introduces the ET (Effective Tokens) metric for normalizing costs across models and emphasizes that run frequency matters as much as per-run savings.

Agent pull requests are everywhere. Here’s how to review them.（GitHub AI/ML）
中文摘要：GitHub 发布了一份审查 AI 生成 Pull Request 的实用指南。随着 Copilot Code Review 处理量突破 6000 万次且增长 10 倍，超过五分之一的代码审查涉及 AI 代理。文章指出，研究表明 AI 生成的代码比人工代码引入更多冗余和技术债务。审查者应重点关注五大红旗：CI 弱化（如删除测试、降低覆盖率阈值）、代码复用盲区（重复造轮子）、幻觉正确性（编译通过但逻辑错误）、代理失联（大型 PR 缺乏实施计划）以及工作流中的不可信输入（提示注入风险）。建议先让 Copilot 进行自动化审查处理机械性问题，人工专注于关键路径追踪和判断，并提供了 10 分钟快速审查清单。
English Summary: GitHub published a practical guide for reviewing AI-generated pull requests. As Copilot Code Review processed over 60 million reviews with 10x growth, more than one in five code reviews now involve AI agents. The article notes research showing AI-generated code introduces more redundancy and technical debt than human-written code. Reviewers should watch for five red flags: CI gaming (removing tests, lowering coverage), code reuse blindness (reinventing utilities), hallucinated correctness (compiles but wrong), agentic ghosting (large PRs without implementation plans), and untrusted input in workflows (prompt injection risks). The guide recommends letting Copilot handle mechanical checks first while humans focus on tracing critical paths and judgment, providing a 10-minute review checklist.

English Summary: Interconnects AI author Nathan Lambert shares observations from visiting leading Chinese AI labs. He found Chinese researchers display extreme humility and pragmatism: students directly participate in core model development, with less ego-driven politics and more focus on engineering over philosophical debates. China's AI ecosystem resembles a collaborative network rather than competing tribes, with mutual respect for DeepSeek's research taste and ByteDance's market dominance. Unlike the West, Chinese tech companies widely adopt a 'build-not-buy' mentality—non-traditional AI firms like Meituan and Xiaomi train general-purpose LLMs to control their stack. The data industry is less developed, with RL environments often built in-house. Despite Nvidia chip constraints, Huawei chips receive positive remarks for inference. The article concludes with concerns about global AI community fragmentation and calls for open ecosystem collaboration.
