Changes on 2026-08-10

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Output Format:** Markdown, concise, insightful, Chinese language. * **Scope:** 3 changed pages (`hooks.md`, `hooks-guide.md`, `terminal-config.md`). * **Goal:** Summarize changes and explain why they matter to developers. 2. **Analyze the Input Data (Diffs):** * **Page 1: `hooks.md`** * *Change:* The table listing event types and matcher values was updated. * *Specifics:* The row for the `Notification` event. * *Old:* "notification type" with values like `permission_prompt`, `idle_prompt`, `auth_success`, `elicitation_dialog`, etc. * *New:* "notification type" with values `permission_prompt`, `idle_prompt`, `auth_success`, `elicitation_dialog`, `elicitation_url_dialog`, `elicitation_complete`, `elicitation_response`, `agent_needs_input`, `agent_completed`. * *Observation:* Added `elicitation_url_dialog` and `agent_needs_input`, `agent_completed`. *Wait, looking closer at `hooks-guide.md` might clarify if the *values* changed or if it's just a formatting sync.* Let's look at the `hooks-guide.md` diff for the semantic change first. * **Page 2: `hooks-guide.md`** * *Change 1 (Notification Hook Example):* Added a sentence: "See [when each notification type fires](/docs/en/hooks#notification) for the exact timing." This suggests the timing logic is now better documented elsewhere, emphasizing specific behavior. * *Change 2 (Matcher Table for Notification):* * Old: `permission_prompt` -> "Claude needs you to approve a tool use". * New: `permission_prompt` -> "Claude needs you to approve a tool use **and you haven't typed for about 6 seconds**". * Old: `idle_prompt` -> "Claude is done and waiting for your next prompt". * New: `idle_prompt` -> "Claude finished responding about 60 seconds ago **and you haven't typed since**". * New row: `elicitation_url_dialog` -> "An MCP server asks you to open a browser URL and you haven't typed for about 6 seconds". * *Change 3 (Event/Matcher Table at bottom):* * Added `elicitation_url_dialog` to the `Notification` row values. * Added `agent_needs_input` and `agent_completed` to the `Notification` row values. * **Page 3: `terminal-config.md`** * *Change:* Text description of when notifications fire. * Old: "When Claude finishes a task or pauses for a permission prompt, it fires a notification event." * New: "When Claude finishes a task or pauses for a permission prompt, **and you appear to be away from the terminal**, it fires a notification event. See [when each notification type fires](/docs/en/hooks#notification) for the exact timing." 3. **Synthesize the Findings:** * **Core Theme:** The behavior of `Notification` events has been refined to be smarter—specifically, they now have a "presence detection" (idle time) mechanism to avoid spamming the user if they are actively working in the terminal. * **Specific Changes:** * Added logic: Notifications only fire if the user hasn't typed for a specific duration (e.g., 6 seconds for prompts, 60 seconds for idle). * New event type: `elicitation_url_dialog` added for MCP URL prompts. * Documentation clarification: Cross-referenced the exact timing conditions across all three pages. 4. **Drafting the Response (Internal Monologue/Drafting in Chinese):** * *Overall Summary:* Documentation updated to clarify that `Notification` hooks now have idle-timeout conditions (anti-spam) and added a new MCP event type. * *Key Themes:* * **Smart Notification Logic:** Notifications aren't immediate anymore; they wait to see if the user is "away" (idle for ~6s or ~60s). This is a UX improvement. * **New MCP Feature:** Added support for `elicitation_url_dialog`. * **Documentation Refinement:** Better cross-linking and clearer definitions of *when* events fire. * *Impact Level:* Medium. It's not a breaking API change, but it changes the *behavior* of existing hooks (they might fire less often or later than expected). Developers relying on immediate notifications might be confused if they don't read the docs. * *Action Items:* * Review notification hooks if you relied on immediate firing (it's now delayed by idle time). * Update custom hooks to handle the new `elicitation_url_dialog` if relevant. * Check the updated `hooks.md` table for the full list of notification matchers. 5. **Refining the Output (Polishing the Chinese):** * *Summary:* 文档主要更新了 `Notification` 事件的行为描述，明确了触发通知的“闲置检测”机制（即仅在用户看起来离开终端时才触发），并新增了 MCP 服务器的 URL 对话框事件。 * *Themes:* * **智能通知防扰:** `permission_prompt` 和 `idle_prompt` 等事件现在增加了“约 6 秒”或“约 60 秒”的防抖逻辑，仅在用户未输入时触发。 * **新增 MCP 事件类型:** 引入了 `elicitation_url_dialog`，用于处理 MCP 服务器请求打开浏览器 URL 的场景。 * **文档精确化:** 跨页统一了事件触发时机的描述，并添加了指向详细定义的链接。 * *Impact:* Medium. (Behavior change, not syntax change). * *Action Items:* Check hooks relying on immediate notifications. Add support for new URL dialog event if needed. 6. **Final Review against constraints:** * Format: Markdown? Yes. * Language: Chinese? Yes. * Concise/Insightful? Yes. 7. **Final Output Generation** (Proceed to generate response based on step 5).

1. **Understand the Goal**: The user wants a concise, insightful analysis of a single documentation change (a CHANGELOG.md file) in Chinese. The persona is a world-class programmer. 2. **Analyze the Input**: * **File**: `CHANGELOG.md.md` * **Changes**: Added version 2.1.227 with 6 bullet points (Bug fixes and improvements). * **Content Details**: * *Fix 1*: Feature flags evaluated without subscription tier on expired login sessions (Max plan users wrongly prompted for credits). * *Fix 2*: Bash commands failing under `claude-code-action` with `allowed_non_write_users` on GitHub runners. * *Fix 3*: `/tui` bringing back incorrectly rewound conversations. * *Improve 1*: Slash-command menu UI (blue selection, bolded matches, glyph preservation). * *Improve 2*: Performance (fewer event-loop stalls). 3. **Determine the Structure**: * 1. Overall Summary * 2. Key Themes * 3. Impact Level * 4. Action Items 4. **Drafting the Content (Internal Monologue/Trial)**: * *Summary*: This update 2.1.227 is a maintenance release. It fixes annoying bugs regarding subscription logic, GitHub Actions compatibility, and TUI state, while polishing UI and performance. It's not a big feature release, just quality of life. * *Key Themes*: * Bug fixes (Authentication/Subscription, CI/CD, UI State). * UX improvements (Menus, Visual feedback). * Performance optimization. * *Impact Level*: Low to Medium. These are fixes and polish, not breaking changes. However, the GitHub Actions fix is important for CI/CD pipelines, and the subscription fix prevents confusion for paid users. Let's go with "Low" generally, maybe "Medium" if you are heavily using those specific broken features. Actually, the prompt asks for one level. I'll choose "Medium" because the GitHub Actions fix and Subscription fix solve high-friction annoyances. * *Action Items*: * Update dependencies if you were hitting the GitHub Actions error. * Enjoy the cleaner slash menu. 5. **Refining into Chinese (Target Language)**: * *Summary*: 此次更新 (v2.1.227) 主要包含关键 Bug 修复和用户体验改进。解决了订阅状态误判、CI/CD 环境命令执行失败以及 TUI 状态回溯问题，同时优化了命令菜单视觉反馈和性能。 * *Key Themes*: * 订阅与身份验证修复 * GitHub Actions 兼容性 * UI/UX 细节打磨 * 性能优化 * *Impact Level*: **Medium** (中等)。虽然不包含破坏性变更，但修复了影响付费用户体验和 CI/CD 集成的关键问题。 * *Action Items*: * 如果在 GitHub Actions 中遇到 Bash 命令失败，请更新至最新版本。 * 无需修改代码，但可以期待更流畅的交互体验。 6. **Final Polish (Markdown Format)**: ```markdown 1. **Overall Summary**: 此次更新 v2.1.227 是一次维护性发布，重点修复了订阅状态误判和 GitHub Actions 环境下的命令执行失败问题，并优化了 UI 细节与事件循环性能。 2. **Key Themes**: - **关键 Bug 修复**：修正了登录 token 过期时订阅层级的错误判定，以及 GitHub runners 上的 Bash 命令执行失败问题。 - **TUI 状态恢复**：解决了 `/tui` 命令在对话回溯后状态不一致的问题。 - **体验与性能优化**：改进了斜杠命令菜单的视觉高亮逻辑，并减少了因文件检查导致的性能卡顿。 3. **Impact level**: **Medium** (中等) - **Reasoning**: 虽然没有引入破坏性变更，但修复了影响 Max 计划用户（付费提示错误）和 CI/CD 流程（GitHub Actions 兼容性）的高痛点问题，对特定用户场景有显著正面影响。 4. **Action items for developers**: - 如果您的 CI/CD 流程中使用了 `claude-code-action` 且遇到 Bash 命令失败，建议尽快更新。 - 无需修改现有代码，更新后将自动获得更准确的订阅状态提示和更流畅的交互体验。 ``` 7. **Review against constraints**: * Markdown format? Yes. * Chinese reply? Yes. * Concise and insightful? Yes. *Self-Correction during drafting*: Make sure to highlight the specific technical detail about `allowed_non_write_users` in the impact reasoning, as that's a specific technical constraint that was blocking people. 8. **Final Output Generation**.

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** Three pages with diffs (`desktop.md`, `settings.md`, `sub-agents.md`). * **Output Format:** Markdown, concise, insightful. * **Language:** Chinese (requested: "请用中文回复"). * **Structure:** 1. Overall Summary (1-2 sentences). 2. Key Themes across pages. 3. Impact level + reasoning. 4. Action items for developers (max 5). 2. **Analyze the Diffs:** * **`desktop.md` (+1 / -1):** * *Old:* "In sessions where cross-session messaging is enabled, Claude can separately list and message your other Claude Code sessions on the machine, including terminal sessions." * *New:* "[Cross-session messaging](/docs/en/cross-session-messaging) separately lets Claude message [your other Claude Code sessions](/docs/en/cross-session-messaging#see-which-sessions-claude-can-reach), including terminal sessions." * *Analysis:* The change is mostly about adding specific cross-references (links) to the cross-session messaging documentation within the existing text. It clarifies that this feature is handled by "cross-session messaging" and links to a section about "which sessions Claude can reach". * **`settings.md` (+133 / -133):** * *Observation:* The diff provided is truncated (`...`). It shows the start of a table in `settings.json` documentation. The context implies a formatting change or a structural update to how settings are documented (e.g., markdown table syntax adjustments, column alignment, or potentially just a large chunk being reformatted but the content looks mostly similar in the visible part). However, since I can't see the *full* diff, I must rely on the visible part. The visible part looks like the start of a table definition. * *Wait, let's look closer at the prompt context.* The prompt says "Total changed pages: 3". The `settings.md` diff shows a truncated table. Usually, a diff with +133/-133 on a markdown table suggests a reformatting of the whole table (e.g., wrapping lines, column widths) or perhaps a restructuring of the list. Without the full diff, I cannot be 100% sure of *content* changes, but it looks like a reformatting effort to improve readability or consistency. * *Hypothesis:* The `settings.md` change is likely a table reformatting. Since the user wants a summary of *what matters*, if it's just formatting, it matters less, but if the table structure changed (e.g., columns renamed), it matters more. Given the snippet looks identical in content structure ("Key", "Description", "Example"), it's likely a reformat. * **`sub-agents.md` (+1 / -1):** * *Old:* "...message [your other Claude Code sessions](/docs/en/cross-session-messaging) on this machine, or reply to your sessions [beyond it](/docs/en/cross-session-messaging#message-sessions-on-other-machines)." * *New:* "...message [your other Claude Code sessions](/docs/en/cross-session-messaging), on this machine or [beyond it](/docs/en/cross-session-messaging#message-sessions-on-other-machines)." * *Analysis:* A minor grammatical restructuring to improve flow. The comma moves, making "on this machine" a modifier to the sessions rather than a separate clause. It links "your other Claude Code sessions" to the main doc, and "on this machine or beyond it" flows into the specific "message sessions on other machines" link. 3. **Synthesize the Findings:** * **Overall Summary:** The changes are primarily documentation refinements focusing on improving navigation links and readability. There are no breaking changes or new features introduced; instead, the focus is on clarifying the scope of "cross-session messaging" and linking related documentation more precisely. * **Key Themes:** * **Navigation/Linking:** Adding specific deep links (anchors) to `cross-session-messaging` docs (`#see-which-sessions-claude-can-reach`). * **Readability/Formatting:** Minor grammar tweaks in `sub-agents.md` and likely a reformatting of the settings table in `settings.md` to handle the content better. * **Clarification of Scope:** Explicitly distinguishing which Claude sessions can be reached via the messaging feature. 4. **Determine Impact Level:** * **Impact:** Low. * **Reasoning:** These are text-only changes (typo/link/grammar/formatting). No API changes, no behavioral changes in the software. Developers don't need to change code or configuration. 5. **Determine Action Items:** * Since the impact is low documentation-only, action items are minimal. * Maybe review the new links if they are confused about cross-session capabilities. * Basically: "None required, just good to know." 6. **Drafting the Response (in Chinese):** * *Summary:* 本次更新主要是文档的润色和链接优化，未涉及功能或代码层面的变更。重点改进了“跨会话消息”功能的文档导航，增强了相关概念之间的连接。 * *Themes:* * 链接优化：增强了跨会话消息的文档内跳转链接。 * 表述微调：修正了 `desktop.md` 和 `sub-agents.md` 中的语法和句子结构。 * 格式调整：`settings.md` 可能进行了表格格式化（基于 diff 行数推测），以提升可读性。 * *Impact:* Low. 仅文档层面的文字调整，不影响 API 或软件行为。 * *Action Items:* * 无需修改代码或配置。 * 若对跨会话消息功能有疑问，可参考新增的文档锚点链接以获取更具体的解释。 7. **Refining the `settings.md` interpretation:** * The diff shows the beginning of the table. +133/-133 suggests the table rows were wrapped or the markdown table structure was rewritten (e.g., using HTML tables or just adjusting line breaks). Since the visible text is identical, I will assume it's a reformatting for consistency. 8. **Final Polish (Chinese):** Make it sound professional and "world-class". * **Overall Summary:** 本次文档变更主要是润色性更新，旨在提升文档的导航性和可读性。核心改进了关于“跨会话消息”功能的描述与链接，修正了部分语法表达，并无功能层面的增删改。 * **Key Themes:** * **导航链接增强**：在 `desktop.md` 和 `sub-agents.md` 中增加了指向“跨会话消息”文档的深层锚点链接（如 `#see-which-sessions-claude-can-reach`），帮助开发者快速定位特定说明。 * **措辞与语法优化**：微调了句子结构（如 `sub-agents.md` 中的逗号位置），使关于会话消息发送范围的描述更加通顺。 * **文档格式调整**：`settings.md` 中 `settings.json` 表格可能进行了格式化重构，以维持文档风格的一致性。 * **Impact Level:** **Low**。 * **Reasoning:** 所有变更均局限于文档文本和 Markdown 结构，未涉及 API 行为变更、配置项新增或软件功能调整，对现有代码或工作流无影响。 * **Action Items:** * 无需采取任何代码或配置变更行动。 * 若之前对 Claude 能触达哪些“其他会话”存在困惑，可查阅文档中新增的深层链接以获取明确界定。 *Self-Correction during drafting:* Ensure I don't overstate the `settings.md` change since the diff was cut off. Just refer to it as formatting/structure adjustment. 9. **Final Output Generation** (matches the drafted content).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Task:** Analyze a single documentation change (slack.md) and summarize it. * **Output Format:** Concise markdown (Overall Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese. * **Content:** A diff from `slack.md`. 2. **Analyze the Diff:** * **Context:** Warning block in `slack.md` regarding the retirement of the earlier "Claude Code in Slack". * **Change 1:** URL update for "Claude Tag" link. * Old: `https://claude.com/docs/claude-tag/overview` * New: `https://claude.com/product/tag` * **Change 2:** Formatting adjustment. * Old: "Set up Claude Tag for a new workspace; to move..." * New: "[Set up Claude Tag](https://claude.com/docs/claude-tag/overview) for a new workspace; to move..." * **Observations:** * The first link is now a general product page (`/product/tag`) instead of the specific documentation overview (`/docs/...`). * The link text "Set up Claude Tag" is now explicitly linked to the documentation overview that was previously linked in the first sentence. This actually improves the information architecture: the product name links to the product page, and the action "Set up..." links to the setup docs. 3. **Drafting the Analysis (Internal Monologue/Rough Notes):** * *Summary:* Just a URL update for Claude Tag links. They moved the specific doc link to the actionable text. * *Themes:* Link maintenance, better navigation context. * *Impact:* Very Low. It's just updating URLs to correct locations or better landing pages. * *Action Items:* None really, maybe just update bookmarks if the old URL is dead, but usually redirects handle that. 4. **Refining for the "World-class Programmer" Persona (Chinese):** * *Tone:* Professional, precise, concise. * *Translation:* * Summary: 更新了 Slack 文档中关于 Claude Tag 的链接指向。第一个链接指向产品主页，设置步骤文本链接到了具体的文档页面。 * Themes: 链接修正/优化. * Impact: Low. 只是 URL 更改，功能未变。 * Action Items: 如果开发者直接收藏了旧链接，可能需要更新，但影响微乎其微。 5. **Final Polish of the Output Structure:** * **Overall Summary:** 这次更新主要修正了 Slack 文档中关于 "Claude Tag" 的超链接结构，将产品介绍链接与设置文档链接进行了更合理的区分。 * **Key Themes:** * **URL 优化**：将 "Claude Tag" 文本链接从文档页改为产品主页 (`/product/tag`)。 * **导航体验改进**：将原本用于介绍的文档链接 (`/docs/claude-tag/overview`) 移动到了 "Set up Claude Tag" 这个具体的行动号召文本上，逻辑更清晰。 * **Impact Level:** Low * **Reasoning**: 仅涉及超链接 URL 的调整，未涉及 API 变更、功能移除或工作流程改变。通常此类更改属于信息架构的微调。 * **Action items for developers:** * 无需立即采取行动。 * 如果您之前直接收藏了旧的文档 URL (`.../docs/claude-tag/overview`)，请确保新链接仍然有效（通常会有重定向）。 * 遇到迁移问题时，请参考新的链接指向的官方文档。 6. **Review against constraints:** * Chinese response? Yes. * Markdown format? Yes. * Concise? Yes. * Focus on what matters? Yes (URL changes usually don't matter much unless they break, but here it looks like an improvement). 7. **Final Output Generation.** (Proceeding to generate the response based on step 5).

1. **理解目标**：用户希望作为一名世界级程序员，对文档更改进行简明、深刻且专注的分析。输出必须是 Markdown 格式，使用中文，并遵循特定结构：整体摘要、关键主题、影响级别和行动项。输入是来自单个页面（`settings.md`）的差异片段。 2. **分析输入**： * **文件**：`settings.md`。 * **更改统计**：+133 行，-133 行。这强烈暗示是一次大规模的重构或重新格式化，而不是添加了 133 个新设置并删除了 133 个旧设置。如果是功能的添加/删除，通常数值不对称。 * **差异内容**： * 顶部显示了介绍文本：`settings.json` supports a number of options:`（`settings.json` 支持许多选项：）。 * 表头从：`| Key | Description | Example |` 变为了 `| 配置项 | 描述 | 示例 |`（或者更确切地说，查看原始差异，视觉上看起来很乱，但我需要深入查看实际更改）。 * 等等，让我仔细看看提供的 diff。 * 左侧（删除）：英文列标题（`Key`，`Description`，`Example`）。英文描述。 * 右侧（添加）：中文列标题（`配置项`，`描述`，`示例`）。中文描述。 * 第一个键 `advisorModel`：描述现在变成了中文（`服务端...`）。示例保持为 `"opus"`。 * `agent`：描述为中文。 * `agentPushNotifEnabled`：描述为中文。 * `allowAllClaudeAiMcps`：描述为中文。 * `allowedChannelPlugins`：描述为中文。 * **结论**：整个表格都从英文本地化为了中文。没有发生功能变更。结构（表格）保持不变。JSON 键（`advisorModel` 等）保持不变，正如预期的那样，因为这些是代码键。 3. **起草分析（迭代过程）**： * **整体摘要**：`settings.md` 文档已从英文更新为中文。更改将 `settings.json` 配置选项的表格和描述翻译成了中文，而没有修改底层功能或 JSON 键结构。 * **关键主题**： * **本地化（i18n）**：文档翻译/本地化。 * **一致性**：保持表格结构，仅更改内容语言。 * **可访问性**：使配置选项对中文开发者更易理解。 * **影响级别**：**低**（或无）。 * *推理*：更改纯粹是语言学方面的。代码本身、配置键（`advisorModel`、`agent` 等）或工具行为均无变化。开发者无需更改其代码或 `settings.json` 文件。 * **行动项**： * 无（可选操作）。 * *草稿 1*：无需行动。 * *草稿 2（更有帮助）*：阅读中文文档以获得更好的理解，如果这是主要语言的话。 4. **翻译成中文（按要求）**： * *整体摘要*：`settings.md` 文档已完成从英文到中文的全面翻译。更改内容仅涉及将 `settings.json` 配置选项的表格描述和列标题本地化，未涉及功能或配置键的修改。 * *关键主题*： * **文档本地化**：将核心配置参考文档翻译为中文。 * **无功能变更**：代码键、JSON 结构和逻辑保持完全一致。 * **可读性提升**：面向中文开发者优化了配置说明的可读性。 * *影响级别*：**低**。 * *推理*：这是纯粹的语言转换，不影响软件功能、API 或用户现有配置。开发者无需修改任何代码或配置文件。 * *Action items*： * 无需采取任何行动。 * （可选）如果您习惯阅读中文文档，可以直接参考更新后的版本以更清晰地理解各项配置的含义。 5. **根据约束条件进行最终审查**： * 简明扼要？是。 * 有深刻见解？是（识别出是本地化而非代码更改）。 * Markdown 格式？是。 * 关注开发者？是（澄清这不会破坏任何东西）。 * 中文？是。 6. **最终输出生成**：（与步骤 4 中的思维过程相符）。

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** 4 pages of diffs (intro.md, vision.md, prompt-caching.md, structured-outputs.md). * **Task:** Summarize changes and explain why they matter. * **Format:** Markdown, Concise. * **Language:** Chinese. * **Output Structure:** Overall Summary, Key Themes, Impact Level, Action Items. 2. **Analyze Page 1: `intro.md`** * *Diff:* `https://platform.claude.com/cookbooks` -> `https://platform.claude.com/cookbook` (removed 's'). * *Meaning:* A URL typo fix. "Cookbooks" -> "Cookbook". * *Impact:* Negligible to developers (just a link update). 3. **Analyze Page 2: `build-with-claude/vision.md`** * *Diff 1 (Code Snippets):* Multiple instances of `const anthropic = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY });` changed to `const anthropic = new Anthropic();`. * *Meaning:* This implies the SDK now automatically looks for the `ANTHROPIC_API_KEY` environment variable if the constructor isn't provided one, or the documentation is simplifying the examples to assume environment setup is already known (though usually, standard practice in SDKs like OpenAI/Anthropic is to show the explicit init or assume it's elsewhere). Actually, looking at modern SDK conventions, often the API key is required, but if the docs are removing it, it suggests a configuration change or a simplification preference for brevity (implying standard env var loading). *Self-correction:* It's likely just cleaning up boilerplate code in examples to reduce clutter, assuming the developer knows how to instantiate the client or relies on default env var detection. * *Diff 2 (Text):* Pricing text changed from `$1`, `$5`, `$1.30`, `$6.48` to `$1 USD`, `$5 USD`, `$1.30 USD`, `$6.48 USD`. * *Meaning:* Adding currency specification for clarity, likely to avoid ambiguity. * *Impact:* Low. Code simplification in examples; minor text clarity. 4. **Analyze Page 3: `build-with-claude/prompt-caching.md`** * *Diff:* Updated a note about "Mid-conversation system messages". * *Change:* Removed "Claude Sonnet 5" from the list of models that *do not* support this feature. Added "Claude Sonnet 5" to the list of models that *do* support it (alongside Fable 5, Mythos 5, Opus 4.8, Opus 5). * *Meaning:* Feature parity update. Claude Sonnet 5 now supports appending system instructions mid-conversation without invalidating cache. * *Impact:* Medium for developers specifically using Prompt Caching with Sonnet 5. 5. **Analyze Page 4: `build-with-claude/structured-outputs.md`** * *Diff:* Updated the footnote about Amazon Bedrock support. * *Change:* Removed mentions of "natively GA" for Opus 5, Opus 4.8, Sonnet 4.6, etc. Removed mentions of Sonnet 5, Opus 4.7, and Mythos Preview being available via the specific Messages-API Bedrock endpoint. * *New Text:* "On Amazon Bedrock, structured outputs are available for Claude Opus 4.6, Claude Sonnet 4.6, Claude Sonnet 4.5, Claude Opus 4.5, and Claude Haiku 4.5." * *Meaning:* This looks like a restriction or clarification. It explicitly lists older versions (4.6, 4.5) but omits Opus 5, Sonnet 5, Mythos, etc., from the Bedrock list in this specific context. * *Interpretation:* This is potentially a significant limitation clarification. It suggests that on Bedrock, the *latest* models (Opus 5, Sonnet 5) might not support Structured Outputs yet, or the documentation is correcting an error where they were previously listed as supported. Given the removal of Opus 5/Sonnet 5 from the "available" list, this implies a **support gap** on Bedrock for the new models regarding this specific feature. * *Impact:* High/Medium for Bedrock users using new models. 6. **Synthesize and Translate to Chinese:** * *Overall Summary:* 主要是文档的清理、代码示例的简化以及功能支持状态的更新。特别是针对 Prompt Caching（Sonnet 5 现已支持）和 Amazon Bedrock 上的 Structured Outputs（新模型支持范围变更）。 * *Key Themes:* * 代码示例简化：TypeScript 客户端初始化中移除了显式的 API Key 配置（暗示默认环境变量读取）。 * 功能状态澄清：Sonnet 5 现支持对话中途添加系统指令且不破坏缓存。 * 平台兼容性调整：Amazon Bedrock 上的 Structured Outputs 支持模型列表发生变更（移除了 Opus 5, Sonnet 5 等新模型的提及）。 * 文本规范化：货币符号增加 "USD" 后缀，URL 修正。 * *Impact Level:* Medium. * *Reasoning:* Most changes are cosmetic (code simplification, typos). However, the removal of Claude Sonnet 5 and Opus 5 from the Amazon Bedrock structured outputs availability list suggests a potential change in support or a correction of previous inaccurate claims, which affects developers building on that specific platform. * *Action Items:* * 如果您在 Amazon Bedrock 上使用 Sonnet 5 或 Opus 5 的 Structured Outputs，请立即核实该功能当前是否可用，因为文档已将其从支持列表中移除。 * 如果使用 Sonnet 5 进行 Prompt Caching，现在可以利用动态系统指令功能而无需担心缓存失效。 * 更新代码示例以反映最新的客户端初始化最佳实践（虽然显式传 key 依然有效，但新示例更简洁）。 7. **Refining the Output (Self-Correction during drafting):** * Make sure the distinction about the API key code change is clear. It's likely just cleaner docs, not a breaking change in the SDK behavior (SDKs usually still accept the explicit arg). * The Bedrock change is the most "risky" one to flag. * The Prompt Caching change is a "feature enablement". 8. **Final Polish (Markdown & Chinese):** * Structure as requested. *(Drafting content)*: 1. Overall: 这一批次更新主要集中在代码示例的简化、URL 修复，以及针对特定模型（Sonnet 5）和平台（Amazon Bedrock）的功能支持状态修正。 2. Key Themes: - **代码示例简化**: TypeScript 示例中移除了显式的 `apiKey` 传递，倾向于使用环境变量自动加载。 - **功能特性更新**: Claude Sonnet 5 现已支持“中途对话系统消息”且不破坏 Prompt Cache。 - **平台支持范围澄清**: Amazon Bedrock 上的 Structured Outputs 支持列表发生了显著变化，移除了 Opus 5 和 Sonnet 5。 - **细节优化**: 价格描述增加了 "USD" 单位，修正了 Cookbook 的 URL。 3. Impact: Medium (主要是由于 Bedrock 支持列表的变更，可能影响生产环境规划)。 4. Action Items: - 核查 Bedrock: 如果您计划在 Bedrock 上使用 Opus 5 或 Sonnet 5 的 Structured Outputs，请重新确认其可用性。 - 更新缓存策略: 针对 Sonnet 5，您可以开始利用动态系统指令功能。 - 代码审查: 确保代码符合新的初始化风格（尽管旧式初始化依然有效）。 *Checking the vision.md API key change again:* `const anthropic = new Anthropic();`. This suggests the SDK picks up `ANTHROPIC_API_KEY` from env automatically. If a developer hardcodes keys or passes a different variable name, the change is just a doc style, but if they copy-pasted the old code, they might think they *must* pass the object. The new doc shows they don't *have* to. *Checking the Bedrock change again:* Removed Opus 5, Sonnet 5 from the "available" list. This is a big deal if you were assuming they worked. *Checking Prompt Caching change again:* Added Sonnet 5 to the "yes" list. This is a positive change. *Final Translation Check:* "Mid-conversation system messages" -> "中途对话系统消息". "Prompt Caching" -> "提示词缓存". *Let's write the final response.*
