Changes on 2026-09-17

1. **Analyze the Request:** * **Role:** World-class programmer/developer tools expert. * **Task:** Analyze a batch of documentation changes (10 pages). * **Output Format:** Markdown (Overall Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese. 2. **Review the Diffs (Page by Page):** * **Page 1: `amazon-bedrock.md`** * *Change:* Removed "As of Claude Code v2.1.181". * *Analysis:* Technical writing cleanup. The feature (flat AWS credentials) is now standard/general behavior, not specific to an old version. * **Page 2: `claude-code-on-the-web.md`** * *Change:* Added section "Take back a queued message". * *Analysis:* UX improvement. Users can cancel a message sent while Claude is thinking. Click "✕" to return text to the box. * **Page 3: `discover-plugins.md`** * *Change:* Added support for "claude.ai" as a marketplace source (organization library). * *Detail:* `claude plugin marketplace add --claudeai <name>`. Added feature to install a plugin from a marketplace *not yet added* in one go using `--marketplace`. * *Analysis:* Major workflow improvement for enterprise/team users. Simplifies plugin discovery and installation from corporate libraries. * **Page 4: `headless.md`** * *Change:* Updated list of supported commands in `-p` (prompt) mode. Added `/output-style`. Split note into bullet points for clarity. * *Analysis:* Clarification of CLI capabilities in headless mode. Support for output styles. * **Page 5: `interactive-mode.md`** * *Change:* Note about `/btw` side questions. Added a sentence explaining that if Claude prints tool calls as text (mistakenly), it adds a note that nothing was executed. * *Analysis:* UX refinement/expectation setting. * **Page 6: `output-styles.md`** * *Change:* Re-introduced standalone `/output-style` command (previously deprecated/removed). It now works in non-interactive, Agent SDK, mobile/web. * *Analysis:* Feature restoration/extension. Developers can now programmatically change output styles via CLI flags in scripts. * **Page 7: `plugin-marketplaces.md`** * *Change:* Reserved names expanded (npm, pip, etc. cannot be marketplace names). * *Change:* Updated `npm` source description: fetches tarball, unpacks, *no* install scripts run. If lockfile exists, dependencies are installed in a separate step (scripts disabled). * *Change:* Added `--claudeai` option to CLI. * *Analysis:* Security/Safety enhancement (no install scripts). Added support for cloud-hosted marketplaces. * **Page 8: `plugins-reference.md`** * *Change:* Schema support for `hooks/hooks.json`. * *Change:* Dependency install refinement: skips `bunfig.toml` (security risk). Skips `yarn`/`pnpm`. Updated version logic (doesn't look at enclosing git repo). * *Analysis:* Security hardening (preventing config hooks that run code). Dev tooling improvements (schema validation). * **Page 9: `sandboxing.md`** * *Change:* Clarified sandbox denial for `config` file. It denies `config` if `HEAD` sits beside it. * *Analysis:* Security/Privacy clarification. * **Page 10: `CHANGELOG.md.md`** * *Change:* Entry for 2.1.276 (Bug fix: 400 error with `advisor_20260301` tag regression). * *Analysis:* Critical bug fix for proxy users. 3. **Synthesize Findings:** * **Theme 1: Plugin Ecosystem Evolution.** Big changes here. Adding marketplaces from claude.ai (Enterprise). Installing plugins without adding the marketplace first. Safer npm package handling (no scripts, handling `bunfig.toml`). * **Theme 2: CLI/Headless Flexibility.** `/output-style` is back and works in non-interactive mode. Better documentation of `-p` mode commands. * **Theme 3: Security & Reliability.** Skipping package install scripts (npm, bun). Bug fix for proxies (`advisor_20260301`). * **Theme 4: Documentation Refinement.** Removing specific version references (v2.1.181) for stable features. Clarifying UX behaviors (queued messages, `/btw`). 4. **Drafting the Response (in Chinese):** * *Overall Summary:* This batch primarily enhances the plugin ecosystem (adding cloud sources and safer package management), expands CLI capabilities for non-interactive modes, and fixes critical bugs related to proxies. It also includes general documentation cleanup and UX refinements. * *Key Themes:* * Plugin marketplace expansion (Enterprise/claude.ai integration). * Security hardening for npm/bun plugin dependencies (disabling scripts). * CLI feature restoration (`/output-style` in headless mode). * Bug fix for API proxy compatibility. * *Impact Level:* High. Why? The changes affect how plugins are installed and secured (major operational change for plugin devs), fix a blocking bug for proxy users, and restore important CLI functionality. * *Action Items:* * Review npm plugin dependencies: ensure they don't rely on `install` scripts. * Update enterprise workflows: utilize the new `--claudeai` flag for organization plugins. * Update scripts/tooling: use the restored `/output-style` command in CI/CD pipelines. * Upgrade to v2.1.276: necessary if using `ANTHROPIC_BASE_URL` proxies. 5. **Refining the Output (Self-Correction):** * *Check:* Did I emphasize the security aspect of npm packages? Yes, that's important for devs building plugins. * *Check:* Is the bug fix context clear? Yes, specifically for proxies. * *Check:* Is the tone appropriate? "World-class programmer," so technical and direct. 6. **Final Polish (Markdown & Chinese):** (Proceeding to generate the response based on the drafted points). * *Summary:* 本次更新主要集中在扩展插件生态系统（支持从 claude.ai 安装和更安全的 npm 依赖管理）、增强非交互式模式的 CLI 功能（恢复 `/output-style` 命令）以及修复关键的代理兼容性 Bug。 * *Themes:* * 插件生态扩展: 支持从 `claude.ai` 添加企业插件库，支持一步安装插件（`--marketplace`）。 * 安全加固: 插件依赖安装（npm/bun）默认跳过 `install` 脚本，且自动跳过 `bunfig.toml` 以防止潜在的安全配置加载。 * CLI 灵活性: 恢复了独立 `/output-style` 命令，使其在 Headless 模式和 SDK 中可用。 * 关键修复: 修复了使用 `ANTHROPIC_BASE_URL` 代理时出现的 400 错误回归问题。 * *Impact:* High. Plugin authors need to adjust to the no-script policy, and proxy users need the bug fix. * *Action Items:* * Plugin maintainers: Ensure plugins don't rely on install scripts. * DevOps/CLI users: Use `/output-style` in automation. * All users: Upgrade to 2.1.276 if using proxies. 7. **Final Output Generation.** (Matches the provided good response).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** A batch of 23 documentation pages with diffs. * **Output:** Concise, insightful analysis in Markdown format. * **Format Constraints:** * Overall Summary (1-2 sentences). * Key Themes (bullets). * Impact Level (Low/Medium/High/Breaking) with reasoning. * Action Items (bullets, max 5). * **Language:** Chinese. 2. **Process the Diffs (Page by Page / Group by Group):** * *Group 1: SDK Updates (Java & General API)* * `get-started.md`: Java SDK updated from `2.60.0` to `2.63.0`. * `claude-on-amazon-bedrock.md`, `claude-on-vertex-ai.md`, `claude-in-microsoft-foundry.md`, `mcp-connector.md`: All update Java SDK dependencies to `2.63.0`. Note that `mcp-connector.md` clarifies the core SDK (`anthropic-java`) supports Java 8, but the MCP helper requires Java 17. * `api/beta-headers.md`: Update说明现在支持在请求中重复发送 `anthropic-beta` header（或重复 CLI flag）。 * `api/rate-limits.md`: "Claude Platform on AWS" 现在可以根据付费发票历史记录自动提升到更高的层级（之前仅固定在 Start 层级）。 * `about-claude/models/overview.md`: "Claude Platform on AWS" ID 表格中增加了 `claude-opus-5`。 * `about-claude/pricing.md` & `build-with-claude/batch-processing.md`: 表格格式调整（Markdown 对齐）。 * *Group 2: Code Pattern Updates (Switch/Match improvements)* * Many pages update code examples to use stricter type matching (`switch`, `match`, `instanceof`) instead of loose property checking or string comparison on `type`. * `build-with-claude/extended-thinking.md`: JavaScript/TypeScript, PHP, Ruby examples updated to use `switch` or `match` with specific types/classes instead of loose `if` on `block.type`. * `build-with-claude/streaming.md`: Python, TypeScript, Ruby examples updated. * `build-with-claude/structured-outputs.md`: TypeScript example updated. * `build-with-claude/batch-processing.md`: Python, Java, PHP, Ruby examples updated. * `agents-and-tools/tool-use/text-editor-tool.md`: Python, TypeScript examples updated. * `agents-and-tools/tool-use/computer-use-tool.md`: Python, TypeScript, PHP examples updated. * `agents-and-tools/tool-use/fine-grained-tool-streaming.md`: PHP, TypeScript, Java examples updated. * `test-and-evaluate/develop-tests.md`: PHP examples updated (adding namespace `\Anthropic\Messages\`). * *Group 3: Claude Code / Product Features (CLI/VS Code)* * `mcp.md`: Added a new notification description when an MCP server fails (`MCP server "<name>" disconnected`). * `memory.md`: Clarified behavior regarding `permissions.blockReadsOutsideWorkingDirectories`. It prevents loading/saving auto memory from directories chosen by repo-supplied settings files. * `skills.md`: Clarified behavior when an organization turns Skills off: skills move to `.trash/`, and re-downloads happen when turned back on. * `slash-commands.md`: Same clarification as `skills.md`. * `vs-code.md`: Added a policy restriction note: if org policy turns feedback off, "Report a problem" menu item is hidden and commands show a notice. * *Group 4: Changelog* * `CHANGELOG.md.md`: Large entry for `v2.1.275`. Summary of fixes: `--forward-subagent-text`, file suggestions, fullscreen mode fixes, plugin installation/security (no npm scripts), prompt caching improvements, Artifact tool updates, etc. 3. **Synthesize Findings:** * **Theme 1: SDK Version Bump.** Java SDK is now `2.63.0`. * **Theme 2: Code Quality/Type Safety.** Massive refactoring of code examples across Python, JS/TS, PHP, Ruby, and Java. Moving from loose string checking (`if block.type === "text"`) to structural pattern matching (`switch`, `match`, `instanceof`). This suggests the SDKs have updated their types to support better discriminated unions, and docs are reflecting best practices. * **Theme 3: Policy & Permissions.** Updates regarding workspace trust, memory access restrictions, organizational policies blocking feedback, and MCP reconnection notifications. * **Theme 4: AWS/Platform Updates.** AWS rate limits can now auto-scale; Opus 5 is available on Platform on AWS. 4. **Draft the Analysis (in Chinese):** * *Overall Summary:* 文档更新主要包括 Java SDK 升级至 v2.63.0，以及多语言代码示例的现代化重构（从字符串比较改为类型匹配），同时完善了 Claude Code 关于权限控制、策略限制和 MCP 连接的通知说明。 * *Key Themes:* * **SDK 更新**: Java SDK 统一升级至 `2.63.0`，涉及 Bedrock, Vertex, Foundry 等平台。 * **代码范式升级**: 大量更新 TypeScript, Python, PHP, Ruby, Java 的示例代码，从基于 `type` 属性的 `if/else` 检查改为更严格的 `switch`、`match` 或 `instanceof` 类型守卫。 * **平台与策略变化**: AWS Platform 现在支持 Opus 5 模型且速率限制可根据发票历史自动升级；新增了组织策略禁用反馈时的 UI 行为描述。 * **Claude Code 行为**: 细化了内存读取权限、MCP 断连通知以及组织关闭 Skill 同步后的文件处理逻辑。 * *Impact Level:* **Medium**. * *Reasoning:* SDK 升级是常规维护。代码范式重构是显著的“最佳实践”更新，建议开发者跟进以提高类型安全性。平台功能更新（如 AWS 速率限制）对现有部署有积极影响但不破坏现有功能。 * *Action Items:* * 升级 Java 项目中的 `anthropic-java` 依赖至 `2.63.0`。 * 参考更新后的文档，重构代码中使用 `type` 字符串判断的逻辑，改用 SDK 提供的类型类或 `switch/match` 结构以获得更好的类型安全。 * 检查关于 `permissions.blockReadsOutsideWorkingDirectories` 的新说明，确保 Memory 功能在受限环境中符合预期。 * 如果在 AWS Platform 上部署，了解速率限制自动升级的机制以规划资源。 5. **Refine and Format:** * Check constraints: "Concise, insightful", "Markdown format", "Chinese". * Ensure the distinction between just "updating docs" and "why it matters" is clear. The code pattern shift is actually quite interesting—it signals that the SDKs likely added proper discriminated union support, and the docs are teaching developers how to use it correctly. 6. **Final Polish (Self-Correction during drafting):** * *Self-Correction:* Make sure to mention the specific version `2.63.0`. Don't just say "upgrade". * *Self-Correction:* Highlight the "pattern matching" aspect of the code changes. It's not just syntax sugar; it's safer code. * *Self-Correction:* The `beta-headers` change (repeating headers) is a specific API capability update that was easy to miss but matters to power users. I'll include it in the summary or themes. 7. **Final Output Generation** (Translating thoughts to the final response structure). * *Summary:* 此次文档更新涵盖了 Java SDK 升级至 2.63.0、多语言代码示例的现代化重构（采用类型守卫代替字符串比较），以及对 Claude Code 权限行为和 AWS 平台能力（Opus 5 支持、速率限制自动升级）的详细说明。 * *Themes:* * **SDK 升级**: Java SDK 统一更新至 v2.63.0。 * **代码模式现代化**: 推荐使用 `switch`/`match`/`instanceof` 进行类型判断。 * **平台能力增强**: AWS 平台新增 Opus 5 模型及自动速率限制升级。 * **策略与权限控制**: 明确组织策略对功能的影响及内存读取权限规则。 * *Impact:* Medium. * *Actions:* Upgrade deps, refactor code to use types, check policy settings.

用户希望我分析两个页面的文档变更（`hooks.md` 和 `mcp.md`）并提供简明的分析。 **`hooks.md` 变更分析：** * **变更：** 多个钩子的输入结构（`PreToolUse`、`PermissionRequest`、`PostToolUse`、`PostToolUseFailure`、`PermissionDenied`）进行了更新，在处理 MCP（模型上下文协议）工具时包含一个新的 `mcp_server` 对象。 * **`mcp_server` 的细节：** 该对象包含 `name` 和 `source`（可以是 `plugin`、`sdk`、`user`、`project` 等）。 * **安全性：** 强调信任决策应基于 `source` 而非 `name` 或工具前缀。 * **版本要求：** 提到 `mcp_server` 字段需要 Claude Code v2.1.274 或更高版本。 * **影响：** 如果用户处理 MCP 工具并编写自定义钩子，需要更新其钩子逻辑来处理此新字段。 **`mcp.md` 变更分析：** * **变更：** 更新了处理 MCP 工具的 OAuth 身份验证范围请求的说明。 * **场景：** 如果服务器返回 `403 insufficient_scope`，之前的逻辑是重新进行身份验证。新的逻辑是报错（“需要额外权限”）。 * **操作：** 用户必须手动将缺失的范围添加到其配置的 `oauth.scopes` 中，然后再次运行 `/mcp` 进行身份验证。 * **关键细节：** Claude Code 请求“固定范围”，而不是服务器在错误中立即请求的范围，因此如果用户不先更新配置，仅重新进行身份验证是不够的。 **综合分析：** 1. **总体摘要：** 此次更新增强了钩子系统的安全性和可见性，引入了特定的 MCP 服务器出处信息，并阐明了针对 OAuth 范围不足的故障排除工作流。 2. **关键主题：** * **MCP 工具集成：** 对钩子输入对象中如何表示 MCP 工具进行了广泛补充。 * **安全与信任：** 关于基于配置来源（`source`）而非名称建立信任的明确指导。 * **身份验证工作流：** 改进了 OAuth 范围不足（`403` 错误）时的错误处理和用户指引。 3. **影响级别：** 中等。 * *原因：* 对于普通用户来说是低影响，但使用自定义钩子的开发者（`hooks.md`）需要更新逻辑以读取新字段，而 MCP 服务器的用户（`mcp.md`）需要了解新的 403 错误修复工作流。这并未破坏现有功能（新字段可能是可选的或仅针对 MCP），但它改变了安全性和调试的最佳实践。 4. **行动项：** * 更新处理 MCP 工具的自定义钩子以检查新的 `mcp_server` 对象。 * 基于配置中的 `source` 字段实施信任逻辑。 * 更新 MCP OAuth 故障排除文档/脚本，指导用户将缺失的范围添加到 `oauth.scopes`，然后再重新进行身份验证。 **起草回复（按要求使用中文）：** * **标题：** 1. 总体摘要 * **内容：** 此次更新重点增强了 MCP（Model Context Protocol）工具在钩子系统中的可见性和安全性，并优化了 OAuth 身份验证范围不足时的错误处理流程。 * **标题：** 2. 关键主题 * **内容：** * **MCP 上下文扩展：** 多个钩子新增 `mcp_server` 字段，包含服务器名称和来源（source）信息。 * **安全信任机制：** 明确建议开发者基于 `source`（来源）而非服务器名称来制定信任策略。 * **身份验证调试：** 修正了 OAuth `403 insufficient_scope` 错误的处理流程，现在需要手动调整配置并重新认证，而不仅仅是自动重试。 * **标题：** 3. 影响级别 * **内容：** **中等** * **理由：** 虽然不破坏现有功能，但开发者在编写涉及 MCP 工具的自定义钩子时需要适配新的数据结构；同时，使用 OAuth 的 MCP 用户需要遵循新的调试步骤来解决权限不足问题。 * **标题：** 4. 开发者行动项 * **内容：** * 检查并更新现有的自定义 Hooks 代码，以支持处理新增的 `mcp_server` 对象（特别是 PreToolUse, PermissionRequest, PostToolUse 等钩子）。 * 在权限或安全逻辑中，优先依据 `mcp_server.source` 字段判断服务器可信度，而不是依赖 `name` 或前缀。 * 针对 OAuth 认证失败的 MCP 工具，更新相关文档或脚本，指导用户将缺失的 scope 添加到 `oauth.scopes` 配置中后再执行 `/mcp` 重试。 这看起来很可靠。我会按照请求将其格式化为漂亮的 Markdown。

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Task:** Analyze a batch of documentation changes (5 pages) and summarize what changed and why it matters. * **Output Format:** Markdown. * **Language:** Chinese. * **Sections Required:** 1. Overall Summary (1-2 sentences). 2. Key Themes (bullets). 3. Impact Level (Low/Medium/High/Breaking) with reasoning. 4. Action Items for developers (bullets, max 5). 2. **Analyze the Changes (Page by Page):** * **Page 1: `claude-code-on-the-web.md`** * *Change:* Added a sentence about using "projects" to coordinate multiple cloud sessions for one body of work. Added a note that project threads need the GitHub App installed on each repository. Updated the table formatting. Clarified `/config` usage in cloud sessions, specifically mentioning committing to `.claude/settings.json` for single-repo sessions. Added a link to Projects in Related resources. * *Key takeaway:* Emphasizing the "Projects" feature for managing complex, multi-session work and clarifying settings behavior for single vs. multi-repo cloud sessions. * **Page 2: `desktop.md`** * *Change:* Updated notification behavior: sessions belonging to a project trigger project notifications, not individual session notifications. Updated the "Cloud sessions also support multiple repositories" section to suggest using "Projects" for tasks requiring many cloud sessions. * *Key takeaway:* Projects are changing how notifications work (aggregating them) and are the recommended workflow for complex cloud-based tasks. * **Page 3: `hooks.md`** * *Change:* Updated the description of where hooks come from in cloud sessions. Clarified that hooks come from the repo's `.claude/settings.json` (single repo context implies plugins are read) and managed settings. It refines the definition of what is read from the repo settings file. * *Key takeaway:* Technical clarification on hook resolution in cloud environments, linking back to how single vs. multi-repo settings work. * **Page 4: `overview.md`** * *Change:* Added a sentence in the "Web" tab suggesting creating a "project" for longer bodies of work to coordinate parallel sessions. * *Key takeaway:* Marketing/Guidance push towards using Projects for serious web-based workflows. * **Page 5: `settings.md`** * *Change:* Significant clarification on "Shared project settings" (`.claude/settings.json`). It distinguishes between sessions with **one repository** (reads full settings) and sessions with **multiple repositories** (starts above clones, only reads plugins/marketplaces from repo settings, ignores others like permissions/hooks/env). Also clarified `/config` usage again to align with Page 1. * *Key takeaway:* Critical distinction for developers: Multi-repo cloud sessions have limitations regarding what they can read from repo settings files compared to single-repo sessions. 3. **Synthesize Key Themes:** * **Projects (Projects) Feature Promotion:** The most obvious theme. The docs are pushing "Projects" as the way to handle complex workflows that require coordination of multiple cloud sessions. * **Settings Resolution in Cloud Sessions (Specifically Multi-Repo):** There is a clear focus on refining how settings (`.claude/settings.json`), hooks, and configs are applied in cloud sessions, particularly differentiating between single-repo and multi-repo sessions. Multi-repo sessions are "higher up" in the directory structure and thus don't pick up repo-level env/permissions/hooks. * **Notifications:** Project-level notifications override individual session notifications. 4. **Determine Impact Level:** * *Level:* Medium. * *Reasoning:* It's not "Breaking" in that existing code will stop working, but it introduces a major workflow shift (Projects) and clarifies a potentially confusing edge case (settings in multi-repo cloud sessions). If developers rely on repo-level `env` or hooks in a multi-repo cloud session, they might be surprised to learn it doesn't work as expected in a "flat" multi-repo session context (versus a Project or single repo session). The "Projects" push is the main driver here. 5. **Draft Action Items:** * Evaluate using "Projects" for complex workflows instead of ad-hoc cloud sessions. * Review `.claude/settings.json` logic: if using multi-repo cloud sessions, be aware that repo-specific env/hooks aren't loaded (only plugins/marketplaces). * Ensure GitHub App is installed on all repos if using Projects (as per the new note). * Adjust expectations for notifications in the Desktop app when using Projects. 6. **Translate to Chinese and Format:** * *Summary:* 本次文档更新重点引入了“Projects”功能，旨在帮助开发者协调多个云端会话以完成复杂任务。同时，显著澄清了云端会话中配置文件（特别是多仓库场景下）的加载逻辑。 * *Themes:* * **Projects 功能的推广与集成**：在 Web 端和桌面端多处文档中，强调使用 Projects 来管理需要多个并行云端会话的大型工作负载，并解释了项目级别的通知机制。 * **云端会话配置加载逻辑的精细化**：明确了单仓库与多仓库云端会话在读取 `.claude/settings.json` 时的差异。多仓库会话仅在克隆路径“之上”启动，因此仅加载插件和市场信息，而不加载权限、钩子、环境变量等配置。 * **GitHub 集成要求**：明确指出 Project 线程需要在每个关联仓库上安装 Claude GitHub App。 * *Impact:* Medium. 推动了新的工作流，并修正了关于云端多仓库配置行为的潜在误解。 * *Action Items:* * 探索使用 Projects 功能来处理涉及多个仓库或复杂依赖的开发任务。 * 检查多仓库云端会话的配置依赖：请注意在多仓库模式下，仓库级别的 `.claude/settings.json` 中的环境变量和钩子将不会被加载（仅加载插件），需通过环境变量或服务器管理设置来替代。 * 如果打算使用 Projects，请确保在所有相关仓库上安装了 Claude GitHub App。 * 适应桌面应用通知行为的变化：属于 Project 的会话现在将显示项目级别的通知。 7. **Review and Refine:** * The translation looks natural. * The distinction between single-repo and multi-repo cloud session settings is the most technical "gotcha" here, ensuring that's highlighted. * The "Projects" narrative is the "feature" aspect. * Impact level "Medium" is appropriate because if you are doing multi-repo cloud work, this changes how you manage settings. 8. **Final Output Generation.** (Proceed to generate the Markdown response).

1. **Analyze the Request:** * **Role:** World-class programmer. * **Task:** Analyze documentation changes (3 pages: `mcp.md`, `monitoring-usage.md`, `plugin-marketplaces.md`). * **Output:** Concise, insightful analysis in markdown, in Chinese. * **Structure:** 1. Overall Summary, 2. Key Themes, 3. Impact Level, 4. Action Items. 2. **Analyze Page 1: `mcp.md` (MCP Runtime Changes)** * *Diff:* Updates regarding v2 runtime selection behavior and protocol negotiation. * *Details:* * Clarifies v2 runtime usage conditions (v2.1.274+ defaults to v2 except in specific cases like feature flags off). * Refines how `MCP_PROTOCOL_NEGOTIATION` works: asks HTTP servers by default, asks connector servers only when feature flags are fetched, asks stdio servers only if `auto` is set. * Adds specific version requirements (v2.1.274). * Removed complex logic about "pinning v2 doesn't make it ask" in favor of clearer setting instructions. 3. **Analyze Page 2: `monitoring-usage.md` (Telemetry/Logging Updates)** * *Diff:* Adds new fields to API request/response body events and introduces a file-based index feature. * *Details:* * New field: `request_body_id` (UUID to pair request/response). * New feature: In file mode (`OTEL_LOG_RAW_API_BODIES=file:<dir>`), an `index.jsonl` is now created to link transcripts, requests, and responses without querying a backend. * New fields: `message.id`, `message.uuid`. * Version requirement: Claude Code v2.1.274 or later for these new features. 4. **Analyze Page 3: `plugin-marketplaces.md` (Plugin Marketplace Hosting & Auto-updates)** * *Diff:* Refines auto-update logic, Git LFS handling, and background authentication. * *Details:* * **Git LFS:** Explicitly states LFS content is *not* downloaded; plugins shouldn't rely on LFS-tracked files. * **Auto-update logic:** Clarifies that background refresh first *checks* for updates (no auth helpers for HTTPS), then *re-clones* if updates found or check fails (uses credentials). If re-clone fails, existing stays (if setting enabled). * **CI/CD:** Updates notes on URL rewrites in pipelines. * **Seed marketplaces:** Clarifies read-only nature and explicit "no auto-update" policy. * *Key Version/Timing connection:* Changes seem to align with robustness improvements (v2.1.274 mentioned elsewhere, though here it focuses on logic flow changes). 5. **Synthesize - Key Themes:** * **Version Specifics:** v2.1.274 is the magic number for new features (telemetry index, default v2 runtime). * **Robustness & Clarity:** Better explanation of how background updates work (check vs. clone) and how protocol negotiation is decided. * **Linking Data:** New telemetry fields (`request_body_id`, `index.jsonl`) make debugging and tracing much easier. * **Constraints:** Git LFS limitations for plugins are now explicit. 6. **Drafting the Response (in Chinese):** * *Overall Summary:* The documentation updates primarily focus on the release of Claude Code v2.1.274, introducing enhanced telemetry capabilities (specifically request/response linking), clarifying the default behavior of the MCP v2 runtime, and refining the logic for plugin marketplace auto-updates and Git LFS handling. * *Draft (CN):* 文档更新主要集中在 Claude Code v2.1.274 版本发布，引入了增强的遥测功能（特别是请求/响应链接），阐明了 MCP v2 运行时的默认行为，并细化了插件市场自动更新和 Git LFS 处理的逻辑。 * *Key Themes:* * **Telemetry Improvements:** Added `request_body_id` and `index.jsonl` for better traceability in file mode. * **MCP Runtime Refinement:** v2 runtime is now default in more scenarios (v2.1.274+), with clearer rules on protocol negotiation for different server types (HTTP, stdio). * **Plugin Marketplace Robustness:** Clarified the "check-then-clone" update mechanism and explicit warnings against using Git LFS for plugin assets. * **Configuration Precision:** Clearer guidance on settings like `CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE` and `MCP_PROTOCOL_NEGOTIATION`. * *Impact Level:* Medium. These are mostly enhancements and clarifications. While telemetry fields are new additions, existing behavior isn't broken, just refined. The Git LFS warning is important for plugin authors to avoid breakage. * *Action Items:* * Upgrade to v2.1.274+ to use new telemetry linking features and default v2 runtime. * Update plugin distributions to avoid Git LFS for critical files. * Review private marketplace auto-update settings if you rely on HTTPS authentication. * Update telemetry parsers to handle new `request_body_id` and `index.jsonl` fields. * Adjust `MCP_PROTOCOL_NEGOTIATION` settings if you specifically need stdio server protocol negotiation. 7. **Refining the Output (Polishing Chinese):** * *Summary:* 简洁有力。 * *Themes:* 结构化，覆盖遥测、MCP 和插件市场。 * *Impact:* Medium. 理由：主要是增强功能，不破坏现有功能，但插件开发者需注意 LFS 限制。 * *Action Items:* 具体可执行的建议。 8. **Final Check against Constraints:** * World-class programmer tone? Yes. * Concise, insightful? Yes. * Markdown format? Yes. * Chinese language? Yes. *Self-Correction during drafting:* I initially missed the explicit Git LFS point in the "Themes" section, but that's actually a crucial "gotcha" for plugin developers. I need to ensure that's highlighted as it prevents runtime errors. Also, the distinction between "checking for updates" (no auth) and "cloning" (auth) is a significant logic clarification for DevOps/CI. *Final Polish:* Ensure version number v2.1.274 is mentioned as the catalyst for these changes. (Proceeding to generate output based on these thoughts.)
