Changes on 2026-05-19

1. **Analyze the Request:** * **Role:** World-class programmer. * **Task:** Analyze documentation changes for a single batch (5 pages). * **Output Format:** Markdown, concise, insightful, Chinese language. * **Input Data:** 5 pages with diffs: `get-started.md`, `api/client-sdks.md`, `build-with-claude/claude-on-amazon-bedrock.md`, `build-with-claude/claude-on-vertex-ai.md`, `build-with-claude/claude-in-microsoft-foundry.md`. 2. **Analyze the Diff Content:** * **Page 1: `get-started.md`** * Change: `anthropic-java` version bump from `2.32.0` to `2.33.0` in Gradle and Maven snippets. * **Page 2: `api/client-sdks.md`** * Change 1: `anthropic-java` version bump from `2.32.0` to `2.33.0` in Gradle and Maven snippets. * Change 2: C# requirement changed from ".NET Standard 2.0" to ".NET Standard 2.0+". * **Page 3: `build-with-claude/claude-on-amazon-bedrock.md`** * Change 1: `anthropic-java-bedrock` version bump from `2.32.0` to `2.33.0` in Gradle and Maven snippets. * Change 2: Text rephrasing in "Global vs regional endpoints" link reference (minor, likely style/consistency). * Change 3: Text rephrasing in logging recommendation ("in order to" -> "to"). * **Page 4: `build-with-claude/claude-on-vertex-ai.md`** * Change 1: `anthropic-java-vertex` version bump from `2.32.0` to `2.33.0` in Gradle and Maven snippets. * **Page 5: `build-with-claude/claude-in-microsoft-foundry.md`** * Change 1: `anthropic-java-foundry` version bump from `2.32.0` to `2.33.0` in Gradle and Maven snippets. 3. **Synthesize Key Themes:** * **Theme 1: Java SDK Release.** All Java-related dependencies (standard, Bedrock, Vertex, Foundry) have been bumped from `2.32.0` to `2.33.0`. This is a coordinated release across all Java integrations. * **Theme 2: Minor Text Improvements.** Small grammatical or stylistic tweaks in the Bedrock documentation. * **Theme 3: Platform Requirement Clarification.** C# requirement specification slightly updated to be more inclusive ("+"). 4. **Determine Impact Level:** * **Level:** Low. * **Reasoning:** Version bumps in SDKs are standard maintenance (assuming no breaking changes are implied by the major version, which is still 2.x). The changes are strictly dependency updates and minor copy edits. There is no indication of API changes or deprecations in the diffs provided. 5. **Determine Action Items:** * Update Java dependencies in projects using the Anthropic SDK (standard, Bedrock, Vertex, or Foundry) to `2.33.0`. * Review changelogs (optional but good practice) to see what specific features/bugfixes are in `2.33.0`. * Note the C# requirement clarification (just informational). 6. **Draft the Response (in Chinese):** * *Overall Summary:* 文档主要更新了 Java SDK 系列依赖项（包括标准版、Bedrock、Vertex AI 和 Foundry 版本）从 2.32.0 升级至 2.33.0，并对 Amazon Bedrock 的部分描述文本进行了轻微优化。 * *Key Themes:* * **Java SDK 全线升级**：所有 Java 相关库（`anthropic-java`, `anthropic-java-bedrock`, `anthropic-java-vertex`, `anthropic-java-foundry`）均从 `v2.32.0` 更新至 `v2.33.0`。 * **平台需求说明**：C# SDK 的要求从 ".NET Standard 2.0" 微调为 ".NET Standard 2.0+"。 * **文档润色**：Amazon Bedrock 页面包含少量的语法和措辞优化。 * *Impact Level:* **Low** (影响低)。这是一次常规的补丁版本升级，涉及依赖更新和轻微的文档文字修正，未发现破坏性变更。 * *Action items:* * 在使用 Java 的项目中，将 `com.anthropic:anthropic-java:*` 及其变体的依赖版本升级至 `2.33.0`。 * 查阅 Java SDK v2.33.0 的官方发布说明（Release Notes），以了解具体的 Bug 修复或新特性。 * 无需紧急修改业务代码，除非新版本修复了您遇到的特定问题。 7. **Refine for "World-class programmer" tone:** * Keep it crisp. Use technical terms correctly. * Ensure formatting matches markdown requirements. 8. **Final Polish (Self-Correction during drafting):** * Make sure to mention *all* the specific java packages affected because developers might only use one and miss the others. * The C# change is technically a requirement update, but practically it's just clarification since 2.0+ includes 2.0. I'll stick to calling it a clarification. 9. **Final Output Generation** (matches the drafted Chinese response).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** 16 pages of documentation diffs. * **Output Format:** Markdown (Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese. * **Focus:** What matters to developers. 2. **Analyze the Diffs (Page by Page):** * **Page: `settings.md` (+5 / -0)** * *Change:* Added section "When edits take effect". Settings files are watched and reloaded automatically (including `permissions`, `hooks`, etc.). Some keys (`model`, `outputStyle`) require restart or specific commands (`/model`, `/clear`). * *Developer Impact:* UX improvement. Developers don't need to restart the CLI for every setting change, only for specific system-level configs. * **Page: `intro.md` (+3 / -3)** * *Change:* Minor wording updates in the Tip box (Claude Opus 4.7, Sonnet 4.6, Haiku 4.5 descriptions). Changed "Our" to "Anthropic's", "Learn more" to "Read the ... announcement". * *Developer Impact:* Negligible. Just brand consistency. * **Page: `about-claude/models/migration-guide.md` (+25 / -12)** * *Change:* * Branding change: "Our" -> "Anthropic's". * Skill improvement: `/claude-api migrate` skill now detects Amazon Bedrock, Vertex AI, AWS, and Foundry clients. * Code updates: Reduced `max_tokens` from 64k to 16k in the example (Opus 4.6 -> 4.7). Changed thinking type. * Parameter details: Prompting to "update `max_tokens`" instead of "we suggest updating". Emphasizing the importance of the `effort` parameter. * Grammar tweaks: "Test max effort" instead of "We recommend testing". * *Developer Impact:* High. Migration path is clearer. The automatic detection of cloud platforms in the migration skill is a significant developer productivity boost. * **Page: `about-claude/pricing.md` (+17 / -15)** * *Change:* * Wording: "we also automatically include" -> "the API also automatically includes". * Formatting: Wrapped JSON snippets in outer objects (standardization). * *Developer Impact:* Low. Formatting/wording. * **Page: `build-with-claude/extended-thinking.md` (+2 / -2)** * *Change:* * Wording: "contact our sales team" -> "contact Anthropic sales". * Wording: "we recommend passing everything back" -> "pass everything back". * *Developer Impact:* Low. Branding/Style. * **Page: `build-with-claude/files.md` (+21 / -22)** * *Change:* * Code examples: Updated TypeScript examples (e.g., `anthropic.beta...` -> `client.beta...`). * Code examples: Updated C# examples (using typed constants, fixing casing `Id` -> `ID`, better stream handling). * Code examples: Updated model IDs to `claude-opus-4-6` (wait, earlier page talked about 4.7, but this one shows 4.6 in examples. Ah, checking the diff... the *previous* version likely had 4.7 or older, the *new* version shows 4.6 in the MessageCreateParams. Actually, looking closely at the C# example: `Model = Messages::Model.ClaudeOpus4_6`. The Python example changes `anthropic` to `client`). * *Correction*: Actually, looking at the context, the main change here is SDK consistency. `anthropic` -> `client`. Stream handling in C# improved. * *Developer Impact:* Medium. Code consistency and correctness in SDK examples. * **Page: `build-with-claude/claude-on-vertex-ai.md` (+3 / -0)** * *Change:* Added Tip promoting `/claude-api migrate` skill for platform-specific migrations. * *Developer Impact:* Medium. Helpful hint. * **Page: `build-with-claude/claude-in-microsoft-foundry.md` (+3 / -0)** * *Change:* Added Tip promoting `/claude-api migrate` skill. * *Developer Impact:* Medium. Helpful hint. * **Page: `agents-and-tools/tool-use/overview.md` (+1 / -1)** * *Change:* Wording: "we also automatically include" -> "the API also automatically includes". * *Developer Impact:* Low. * **Page: `agents-and-tools/tool-use/implement-tool-use.md` (+27 / -0)** * *Change:* Added cURL example for `input_examples` in tool definitions. * *Developer Impact:* Medium. Improves documentation coverage for a feature. * **Page: `agents-and-tools/tool-use/bash-tool.md` (+89 / -0)** * *Change:* Added TypeScript, C#, Go, Java, PHP, and Ruby code examples for using the Bash tool. Previously likely only had Python. * *Developer Impact:* High. Multi-language support for a core tool. * **Page: `agents-and-tools/tool-use/computer-use-tool.md` (+713 / -180)** * *Change:* Massive update to code examples. * Added TypeScript, C#, Go, Java examples (likely replacing or augmenting existing ones). * Updates to warning text ("might" vs "may", "Anthropic" vs "The model"). * C# example uses `void main` (top-level statements). * Go SDK updates (constants pending). * Formatting updates (headers in lists). * *Developer Impact:* High. Expanding language support for Computer Use. * **Page: `agents-and-tools/tool-use/web-search-tool.md` (+4 / -7)** * *Change:* Formatting JSON usage examples (wrapping in outer object). * *Developer Impact:* Low. * **Page: `agents-and-tools/tool-use/web-fetch-tool.md` (+2 / -7)** * *Change:* Formatting JSON usage examples. * *Developer Impact:* Low. * **Page: `agents-and-tools/tool-use/code-execution-tool.md` (+5 / -5)** * *Change:* Formatting JSON usage examples. * *Developer Impact:* Low. * **Page: `CHANGELOG.md.md` (+21 / -2)** * *Change:* New version `2.1.145`. * *Highlights:* `claude agents --json` (scripting), improved trace parenting, plugin discovery UX improvements, `input_examples` support in tools, bash tool security fix, various bug fixes (Windows, voice, review, etc.). * *Developer Impact:* High. New features and critical bug fixes (security/permissions). 3. **Synthesize Findings:** * **Key Theme 1: SDK & Code Example Expansion:** There is a concerted effort to provide examples in TypeScript, C#, Go, Java, PHP, and Ruby for tools like Bash and Computer Use, rather than just Python. * **Key Theme 2: Migration Tooling:** The `/claude-api migrate` skill is being heavily promoted and has been enhanced to detect specific cloud platforms (Bedrock, Vertex, Foundry). * **Key Theme 3: Changelog Feature Additions:** Version 2.1.145 brings JSON output for agent listing (scripting support) and security fixes. * **Key Theme 4: Formatting & Branding:** Consistent changes to JSON formatting (wrapping usage objects) and phrasing ("the API" instead of "we", "Anthropic's" instead of "our"). 4. **Draft the Analysis (in Chinese):** * *Summary:* 主要是 SDK 示例代码的扩展（增加了多语言支持）、迁移工具的增强以及对 Bash 工具的安全修复。此外，还包括配置热加载的说明和文档格式的统一。 * *Themes:* * 多语言 SDK 示例补充：为 Bash、Computer Use 等工具增加了 TypeScript, C#, Go, Java, PHP, Ruby 的代码示例。 * 迁移工具改进：`/claude-api migrate` 现在支持检测和适配 Bedrock, Vertex AI, Foundry 等云平台。 * 新功能与安全修复：CLI v2.1.145 新增 JSON 输出模式，修复了权限绕过漏洞。 * 文档规范化：统一了 JSON 响应格式，去除了以第一人称的表述。 * *Impact:* Medium/High. The migration improvements and multi-language examples are highly beneficial for developers onboarding or upgrading. The security fix is critical. * *Action Items:* * 升级 CLI 到 v2.1.145 以利用新的 JSON 输出功能并修复权限漏洞。 * 查看 `/claude-api migrate` 命令以简化多平台模型迁移。 * 检查 `settings.md` 中关于配置热加载的说明，优化工作流。 5. **Refine the Output:** * *Impact Level:* Medium. While there are breaking changes mentioned in the migration guide context (from model 4.6 to 4.7), the *documentation changes themselves* are mostly informative and additive (examples). However, the security fix and the migration tooling improvement elevate the importance. Let's stick with **Medium** as the *change* level, but note the high utility. Actually, looking at the Changelog, the security fix is "permission-prompt bypass". That's significant. I will classify as **Medium** overall but highlight the security aspect. Wait, usually "Breaking" implies code stops compiling. The docs clarify *breaking changes* in the model. But as an analysis of docs, it's "Medium". Let's stick to the prompt's context. * *Action Items:* 1. Update CLI to v2.1.145 (Security fix + JSON output). 2. Use `/claude-api migrate` for cloud platform upgrades. 3. Review `settings` reload behavior (hot reload available). 4. Check multi-language examples for Bash/Computer Use tools. 5. Adapt `max_tokens` settings if migrating to Opus 4.7. 6. **Final Polish (Markdown & Chinese):** * Ensure clear headings. * Keep it concise. *(Self-Correction during drafting)*: The CHANGELOG entry is quite dense. I need to make sure I capture the `claude agents --json` bit as it's a developer-centric feature for scripting (tmux-resurrect mentioned). *Action Items refinement:* - Upgrade CLI. - Utilize migrate skill. - Check config reload behavior. - Review multi-lang examples. - Adjust migration parameters (effort/max_tokens). Let's write it out. *Overall Summary:* 文档更新主要集中在扩大多语言 SDK 代码示例、增强模型迁移工具的跨平台支持、记录 CLI v2.1.145 版本的重要功能更新及安全修复，并标准化了文档中的 API 响应格式。 *Key Themes:* - **多语言支持扩展**: 为 Bash 工具和 Computer Use 工具新增了 TypeScript, C#, Go, Java, PHP, Ruby 等语言的代码示例。 - **迁移工具增强**: `/claude-api migrate` 技能现在能检测 Amazon Bedrock, Vertex AI, Microsoft Foundry 等平台并自动调整迁移参数。 - **CLI 新功能与修复**: v2.1.145 版本引入了 `claude agents --json` 用于脚本集成，并修复了 Bash 权限绕过等关键 Bug。 - **配置热加载说明**: 明确了 `settings.json` 支持热重载，除 `model` 和 `outputStyle` 外无需重启。 - **文档规范化**: 统一了 API Usage JSON 的输出格式（增加外层包裹），并将措辞从第一人称（"we"）改为客观描述（"the API"）。 *Impact Level:* Medium. (Reasoning: While mostly additive examples and formatting, the migration tooling improvements and the documented security fix in the CLI are highly relevant to active developers). *Action items:* - **立即升级**: 将 Claude Code CLI 升级至 v2.1.145，修复潜在的权限提示绕过漏洞，并尝试新的 `--json` 标志进行会话状态脚本化。 - **利用迁移工具**: 如果正在向 Claude Opus 4.7 迁移或在 Bedrock/Vertex AI 上使用 Claude，运行 `/claude-api migrate` 以自动处理平台特定的模型 ID 和参数变更。 - **调整模型参数**: 根据迁移指南，如升级到 Opus 4.7，需重新评估 `max_tokens` 并利用 `effort` 参数来优化性能和成本。 - **查阅新示例**: 查看 Bash 和 Computer Use 工具的非 Python (如 C#, Go) SDK 实现示例，参考最佳实践。 - **了解配置行为**: 查看 `settings.md` 新增章节，利用配置热加载功能优化开发体验，无需频繁重启会话。 7. **Final Review against constraints:** - Concise? Yes. - Insightful? Yes, noted the shift to multi-lang and migration focus. - Markdown format? Yes. - Chinese? Yes. - Focus on developers? Yes. *Ready to generate.*

1. **Analyze the Request**: * **Role**: World-class programmer analyzing documentation changes. * **Input**: A diff for a single file (`cli-reference.md`), specifically a change to the description of the `--disallowedTools` flag. * **Output Format**: Markdown. * **Language**: Chinese. * **Structure**: 1. Overall Summary, 2. Key Themes, 3. Impact Level with reasoning, 4. Action items. 2. **Analyze the Diff**: * **File**: `cli-reference.md`. * **Flag**: `--disallowedTools`. * **Old Description**: "Tools that are removed from the model's context and cannot be used" (被移除且不能使用的工具). * **New Description**: "Deny rules. A bare tool name removes that tool from the model's context. A scoped rule such as `Bash(rm *)` leaves the tool available and denies only matching calls" (拒绝规则。仅工具名会将其从上下文中移除。作用域规则如 `Bash(rm *)` 则保留工具可用，仅拒绝匹配的调用). * **Example Command**: Remained the same (`"Bash(git log *)" "Bash(git diff *)" "Edit"`), which suggests the example demonstrates both capabilities (global edit removal vs scoped bash blocking) or simply wasn't updated to reflect the nuance perfectly (though the example uses scoped rules for Bash, which aligns with the new description of leaving the tool available but denying calls). 3. **Synthesize the Change**: * This is a significant functional update to the `--disallowedTools` CLI flag. * Previously, it seemed like a blanket ban list for tools. * Now, it supports "scoped rules" (scoped deny rules). This means developers can allow a tool (like `Bash`) but forbid specific dangerous commands within it (like `rm *`), rather than disabling the entire `Bash` tool. * This is a "deny rules" system upgrade. 4. **Drafting the Content (in Chinese)**: * **Overall Summary**: The documentation clarifies and expands the `--disallowedTools` flag to support scoped deny rules, allowing developers to block specific dangerous tool calls without disabling the entire tool. * **Key Themes**: * Granularity: Moving from tool-level blocking to command/argument-level blocking. * Security/Control: Enhanced control over what the AI can execute. * Precision: Differentiating between removing a tool vs restricting specific usage patterns. * **Impact Level**: High (or Medium-High). Reason: It fundamentally changes how the flag can be used, enabling more powerful security sandboxes without breaking functionality. It adds a new dimension (scoped rules) to the existing feature. Let's stick with **High** because it unlocks a new capability (allowing tools while blocking specific calls) that was previously ambiguous or impossible. * **Action Items**: * Review existing usage of `--disallowedTools` if you were using it to block specific dangerous commands (maybe you were removing `Bash` entirely to stop `rm` - now you can be smarter). * Update scripts to use scoped rules for better utility (e.g., allow `Bash` but block `rm`, `sudo`, etc.). * Understand the distinction between "removing context" vs "denying calls". 5. **Refining the Language (Professional Programmer Persona)**: * *Summary*: `--disallowedTools` 的文档更新揭示了该参数的功能增强，现在支持“作用域拒绝规则”，允许在不完全禁用工具的情况下拦截特定的危险调用。 * *Themes*: 细粒度权限控制, 安全沙箱, 功能描述精确化. * *Impact*: High. The change implies a shift from a simple blacklist to a flexible policy engine for tool usage. * *Actions*: Check current scripts. Utilize scoped rules. Read the new semantics carefully. 6. **Final Polish (Markdown formatting)**: * Check against constraints: Chinese response, concise, max 5 action items. * *Self-Correction during drafting*: Is it a "Breaking Change"? Probably not. If you used `"Edit"`, it still removes Edit from context. The new description clarifies that `"Bash(git log)"` acts differently than just removing Bash. It's an enhancement/clarification. 7. **Final Output Generation**: (Proceed to generate output based on these thoughts). * **Summary**: 文档更新了 `--disallowedTools` 参数，将其从单纯的工具黑名单细化为支持“作用域规则”的拒绝策略，允许在不移除工具的情况下拦截特定调用。 * **Themes**: 细粒度权限控制, 安全性增强, 功能语义澄清. * **Impact**: High. Reason: It fundamentally improves control over AI agent behavior by allowing "allow-by-default, deny-specific" patterns rather than just "deny-all" for a tool. * **Actions**: * Audit current usage of `--disallowedTools` to see if you can be more specific. * Implement scoped rules (e.g., `Bash(rm *)`) to block dangerous commands while keeping the tool functional. * Differentiate between removing a tool from context (bare name) vs blocking specific calls (scoped). 8. **Translation check**: * "Scoped rule" -> 作用域规则 / 范围规则. * "Bare tool name" -> 仅工具名 / 裸工具名. * "Context" -> 上下文. *Let's write it out.* 1. **Overall Summary**: 文档更新阐明了 `--disallowedTools` 参数的语义，现在支持“作用域拒绝规则”，允许开发者拦截特定的工具调用（如 `rm *`）而无需完全禁用该工具。 2. **Key Themes**: * **细粒度控制**：从工具级别的禁用升级为对特定参数或命令模式的拦截。 * **安全与实用性平衡**：允许保留工具（如 Bash）的通用功能，同时仅拦截高危操作。 * **语义澄清**：明确了“移除上下文”与“拒绝调用”的区别。 3. **Impact Level**: **High** **Reasoning**: 这不仅是一个文档更新，更暗示了底层能力的重大增强。它解锁了更精细的安全沙箱配置，使得开发者不再需要在“完全禁止工具”和“允许所有操作”之间做非此即彼的选择。 4. **Action items**: * **审查现有配置**：检查当前脚本中是否为了防止某些危险命令（如 `git push` 或 `rm`）而粗暴地禁用了整个 `Bash` 工具。 * **采用作用域规则**：更新配置以使用类似 `Bash(rm *)` 的语法，既保留工具可用性又限制风险。 * **区分使用场景**：区分何时应使用“裸工具名”（彻底移除）与“作用域规则”（限制调用）。 Looks good.

1. **Analyze the Request**: * **Role**: World-class programmer/doc analyst. * **Input**: 11 documentation pages with diffs (markdown format). * **Task**: Summarize what changed and why it matters to developers. * **Output Format**: Markdown (concise, insightful). * **Language**: Chinese. * **Structure**: 1. Overall Summary, 2. Key Themes, 3. Impact Level, 4. Action Items. 2. **Analyze the Diffs (Page by Page)**: * **`amazon-bedrock.md`**: * *Changes*: Removed a note linking to the external platform doc about prompt caching availability. Added a note specifically about Bedrock regions and a warning about checking supported models if cache token counts stay zero. Also changed the link structure for "cache lifetime". * *Significance*: Troubleshooting specific to Bedrock prompt caching. Links updated to internal docs (`/en/prompt-caching`). * **`costs.md`**: * *Changes*: Added a markdown link `[prompt caching](/en/prompt-caching)` where previously it was plain text. * *Significance*: Link consistency/Navigation improvement. * **`discover-plugins.md`**: * *Changes*: Major clarification on marketplaces. * Official marketplace is curated, inclusion is at Anthropic's discretion. * Submission forms add to the *community* marketplace, not official. * Added a new section "Community marketplace" (`anthropics/claude-plugins-community`). * Instructions on how to add the community marketplace manually. * *Significance*: Major process change for plugin developers. Submission flow clarification. Distinction between Official vs. Community marketplaces is now explicit. * **`google-vertex-ai.md`**: * *Changes*: Updated link to prompt caching docs from external `platform.claude.com` to internal `/en/prompt-caching`. * *Significance*: Navigation/Link cleanup. * **`mcp.md`**: * *Changes*: Added a large block of text explaining when `claude.ai` connectors are fetched (only when using Claude.ai auth, not API keys or Bedrock/Vertex). * *Significance*: Critical troubleshooting info for MCP server/connector behavior based on auth method. * **`microsoft-foundry.md`**: * *Changes*: Updated prompt caching link from external to internal. * *Significance*: Navigation/Link cleanup. * **`model-config.md`**: * *Changes*: Updated prompt caching link. Removed verbose explanatory paragraph at the end of the table, replaced it with a concise link to "How Claude Code uses prompt caching". * *Significance*: Cleaner docs, better routing to specific internal docs. * **`output-styles.md`**: * *Changes*: Clarified that output style changes take effect after `/clear` or new session. Added link to prompt caching docs regarding cache behavior. * *Significance*: Clarifies user workflow regarding config changes. * **`plugins.md`**: * *Changes*: Detailed section on submitting to the *community* marketplace vs the *official* marketplace. Clarified the submission process, CI pinning (SHA), and that there is no application process for the official marketplace. * *Significance*: Major clarity for plugin distribution strategy. * **`statusline.md`**: * *Changes*: Added a cross-reference link to prompt caching docs for field definitions (`cache_creation_input_tokens`, etc.). * *Significance*: Navigation aid. * **`sub-agents.md`**: * *Changes*: Added link to prompt caching docs regarding subagents. * *Significance*: Navigation aid. 3. **Synthesize Findings**: * **Theme 1: Prompt Caching Documentation Consolidation**. Almost every page with a mention of prompt caching had its link updated from an external URL (`platform.claude.com`) to an internal relative path (`/en/prompt-caching`). Some text was refactored to point to this centralized doc. * **Theme 2: Plugin Marketplace Strategy Overhaul**. Significant updates in `discover-plugins.md` and `plugins.md`. There is now a clear distinction between the "Official" (curated, invite-only/discretionary) and "Community" (public, via submission form) marketplaces. The submission flow now defaults to the community marketplace. * **Theme 3: Specific Troubleshooting Clarifications**. Added specific notes for Bedrock (cache counts zero) and MCP (auth method affecting connector visibility). 4. **Draft the Response (in Chinese)**: * *Overall Summary*: The batch update focuses on consolidating prompt caching documentation internally, significantly restructuring the plugin marketplace ecosystem (Community vs. Official), and adding troubleshooting details for AWS Bedrock and MCP connectors. * *Key Themes*: * Prompt Caching: Links migrated to `/en/prompt-caching`. * Plugin Ecosystem: Clear split between Official (curated) and Community (open submission). * MCP/Auth: Clarified that Claude.ai connectors depend on active auth method. * Cloud Providers: Bedrock specific troubleshooting added. * *Impact Level*: Medium. (High for plugin developers, Medium for users regarding caching/troubleshooting). * *Action Items*: * Plugin devs: Update expectations—submissions go to Community marketplace, not Official. * Plugin devs: Manual addition of community marketplace required for users (`claude-community`). * Bedrock users: Check model/region support if cache tokens are zero. * MCP users: Check auth status if connectors are missing. * General: Note internal doc links for caching details. 5. **Refine the Output (Self-Correction/Polishing)**: * Make sure the distinction between "Official" and "Community" is sharp, as that's the biggest functional change. * Ensure the tone is professional ("World-class programmer"). * Check the Chinese phrasing (e.g., "Internal relative paths" -> "内部相对路径", "Curated" -> "精选/策展"). 6. **Final Output Generation** (matches the provided good response).

1. **Analyze the Request:** * **Role:** World-class programmer. * **Task:** Analyze a batch of documentation changes (8 pages). * **Output Format:** Markdown (Overall Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese. 2. **Analyze the Input Diffs:** * **`cli-reference.md`**: * `claude rm <id>`: Added clarification that the transcript stays locally and can be resumed. * `--resume`: Added info that v2.1.144 shows background sessions marked with `bg` in the picker. * *Insight:* Better management of background sessions and clarification on data persistence after `rm`. * **`discover-plugins.md`**: * Added note for v2.1.144: "Last updated" date shown in plugin details pane. * *Insight:* Minor UI enhancement for plugin management. * **`headless.md`**: * `system/api_retry` event: Added `model_not_found` to the list of error categories. * *Insight:* Improved error handling/reporting in streaming/headless modes, specifically for model availability issues. * **`hooks.md`**: * StopFailure event: Added `model_not_found` to the list of error types matchable by the matcher. * *Insight:* Consistency with `headless.md` changes; allows hook scripts to catch model-not-found errors. * **`hooks-guide.md`**: * StopFailure event: Same change as `hooks.md` (added `model_not_found` to error types). * *Insight:* Documentation sync for hooks. * **`model-config.md`**: * **Breaking/Behavior Change:** `/model` command now applies *only to the current session* (v2.1.144). It is *not* automatically saved to user settings anymore. * To save: Press `d` in the picker. * Resumed sessions: Keep the model they were saved with, preventing cross-session interference. * *Insight:* Significant behavioral change. Prevents unintended side effects where changing the model in one session accidentally changes the default for others. Improves isolation. * **`monitoring-usage.md`**: * Tracing: Added W3C `traceparent` header integration with Anthropic API for client-server linking. * New Event: `claude_code.hook_plugin_metrics` for official marketplace plugins to emit metrics. * *Insight:* Enhanced observability/tracing capabilities, particularly for plugins. * **`settings.md`**: * `env` setting: Clarification about `NO_COLOR` and `FORCE_COLOR` handling in v2.1.143 (passed to subprocesses but don't affect CLI interface). * *Insight:* Better environment variable handling documentation. 3. **Synthesize and Categorize:** * *Theme 1: Model Isolation & Persistence (`model-config.md`, `cli-reference.md`).* The `/model` command behavior change is the biggest piece. It now affects the current session only. * *Theme 2: Error Handling & Observability (`headless.md`, `hooks.md`, `hooks-guide.md`, `monitoring-usage.md`).* Added `model_not_found` error handling across streams and hooks. Added new tracing headers and plugin metrics. * *Theme 3: Session Management (`cli-reference.md`).* Clarifications on `rm` and `--resume` regarding background sessions. * *Theme 4: UI/UX Polish (`discover-plugins.md`, `settings.md`).* Plugin dates, env color handling. 4. **Draft the Analysis (in Chinese):** * **Overall Summary:** 更新主要集中在 v2.1.144 版本的行为变更，特别是模型选择的持久化逻辑，增强了可观测性（W3C tracing、插件指标），并细化了错误处理与后台会话管理。 * **Key Themes:** * **模型配置行为变更**：`/model` 命令不再自动保存到设置文件，仅作用于当前会话，防止跨会话干扰。恢复会话将保持原有模型。 * **增强的可观测性与监控**：引入 `model_not_found` 错误类型；支持 W3C `traceparent` 头连接客户端与服务端追踪；新增官方插件指标事件。 * **会话与插件管理优化**：改进了后台会话的清理与恢复逻辑；插件详情页新增“最后更新”时间。 * **Impact Level:** **Medium**. * *Reasoning:* The change in `/model` behavior affects daily workflow (saving defaults now requires an explicit key press `d`), which might surprise existing users but prevents accidental config changes. New tracing and error features are additive and low risk. * **Action Items:** * Review scripts or workflows relying on `/model` auto-saving; update user habits to press `d` to save. * Update hooks or monitoring dashboards to handle the new `model_not_found` error type and the new `hook_plugin_metrics` event. * Check if tracing infrastructure needs updates to consume the new W3C traceparent links. 5. **Refine Language:** Ensure professional, concise Chinese suitable for a "world-class programmer". * *Refinement on Impact:* Is it "High"? Probably not "Breaking" in terms of code compilation, but "Behavioral Breaking" for UX. "Medium" is appropriate. * *Refinement on Summary:* Make sure to emphasize the v2.1.144 aspect. 6. **Final Output Generation:** (Proceed to generate markdown). * *Self-Correction during drafting:* Make sure to mention the `rm` behavior change (transcripts staying) as it's a common confusion point. 7. **Final Polish:** Check against the "Action items for developers (max 5)" constraint. 1. Adjust workflows for `/model`. 2. Update monitoring for new error type and metrics. 3. Benefit from new tracing headers. 4. Check color env vars. 5. Update documentation. Looks good.

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** Three pages of diffs (API models list, API files upload, Prompt caching guide). * **Output Format:** Concise markdown (Overall Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese (Simpified). * **Goal:** Explain *what* changed and *why* it matters to developers. 2. **Analyze Page 1: `api/models/list.md`** * *Change:* Updated the count of `UnionMember1` from "21 more" to "22 more". Added a specific item: `"cache-diagnosis-2026-04-07"`. * *Context:* This looks like an enum of model IDs or beta feature headers. * *Implication:* A new model or feature flag has been added. The date suggests it's future-dated (April 2026) or internal testing/naming convention, but it's a new identifier in the system. 3. **Analyze Page 2: `api/beta/files/upload.md`** * *Change:* Identical to Page 1. Updated count "21 more" to "22 more". Added `"cache-diagnosis-2026-04-07"`. * *Context:* This page deals with file uploads. The presence of the same string suggests this new feature/header is applicable to model listing *and* file upload contexts. * *Implication:* This new item isn't just a model ID; it might be a beta header or capability token used across the API. 4. **Analyze Page 3: `build-with-claude/prompt-caching.md`** * *Change:* Two sentences modified. * Sentence 1: Removed "The API runs the full prefill phase (reading your prompt into the model and writing the cache at any `cache_control` breakpoint), then returns immediately..." -> Simplified to "The API reads your prompt into the model and writes the cache at any `cache_control` breakpoint, then returns immediately..." (Removed "runs the full prefill phase"). * Sentence 2: Changed "its content is read during prefill but never answered" to "its content is read into the model but never answered". * *Context:* "Pre-warming" prompt caches. * *Implication:* This is a documentation refinement/clarification. It removes technical jargon ("runs the full prefill phase") and standardizes the description of the process ("read into the model"). It doesn't change functionality, just explains it slightly differently or more accurately. 5. **Synthesize Key Themes:** * **New Feature/Header:** The addition of `"cache-diagnosis-2026-04-07"` across two API endpoints suggests a new beta feature related to cache diagnosis is available or coming soon. * **Documentation Refinement:** The prompt caching doc received minor wording updates for clarity, specifically around the "pre-warming" process. 6. **Determine Impact Level:** * *New Feature:* `"cache-diagnosis-2026-04-07"` looks like a specific beta header/flag. If developers aren't using beta features specifically, it might not matter. But for those deep in the weeds, it's new. * *Wording Change:* Very low impact. * *Overall:* Low to Medium. It's not breaking (just adding an option). It's medium if developers need to know about cache diagnosis capabilities. 7. **Draft Action Items:** * Be aware of the new `"cache-diagnosis-2026-04-07"` identifier if working with beta models or headers. * Note the clarification on pre-warming behavior if implementing cache pre-warming (though the code doesn't need to change based on this text edit). 8. **Drafting the Response (in Chinese):** * *Summary:* The updates introduce a new beta feature identifier `"cache-diagnosis-2026-04-07"` for models and file uploads, and refine the description of the prompt cache pre-warming mechanism. * (Chinese: 本次更新引入了新的 Beta 功能标识符 `"cache-diagnosis-2026-04-07"`，涉及模型列表和文件上传接口；同时微调了提示词缓存预热机制的描述。) * *Themes:* * New Beta Feature: Added `"cache-diagnosis-2026-04-07"`. * Doc Polishing: Clarified the pre-warming process in prompt caching. * (Chinese: 新增 Beta 功能：引入了 `"cache-diagnosis-2026-04-07"`。文档润色：对提示词缓存预热的描述进行了微调。) * *Impact:* Low. It's an addition and a clarification, not a breaking change. * (Chinese: 低。仅为新增选项和描述优化，不涉及破坏性变更。) * *Action Items:* * Check if `"cache-diagnosis-2026-04-07"` is relevant for cache debugging if you are an advanced user. * (Chinese: 如果您正在进行高级调试，请注意新的 `"cache-diagnosis-2026-04-07"` 标识符。) 9. **Refining the Content (Self-Correction):** * *Refinement on the "UnionMember1" bit:* It's not just a model list; it appears in file upload too. It's likely a `beta` header value. * *Refinement on the Prompt Caching:* The change is subtle. Removing "runs the full prefill phase" might be to avoid confusion about whether *decoding* happens. "Max tokens: 0" means no decoding. The new text is more precise. 10. **Final Polish (Chinese Markdown):** * **Overall Summary:** 文档主要新增了名为 `"cache-diagnosis-2026-04-07"` 的 Beta 功能标识符，同时优化了提示词缓存“预热”过程的描述。 * **Key Themes:** * **新增功能标识:** 在模型列表 (`list`) 和文件上传 (`upload`) 接口的 `UnionMember1` 枚举中，新增了 `"cache-diagnosis-2026-04-07"` 选项，从之前的 21 个增加到 22 个。 * **描述准确性:** 在提示词缓存文档中，微调了“预热”请求的工作原理描述，移除了 "runs the full prefill phase" 等表述，使其更侧重于“读取并写入缓存”这一核心动作。 * **Impact Level:** **Low** (低)。仅涉及新功能的添加和文档语言的微调，不影响现有 API 的正常使用。 * **Action Items:** * 关注 `"cache-diagnosis-2026-04-07"` 标识符，如需调试缓存性能，可能需要使用此新的 Beta header。 * 无需更改现有代码，文档描述更新仅用于澄清技术细节。 11. **Final Output Generation** (Matches the request constraints).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** A batch of documentation changes (2 pages: `security.md`, `CHANGELOG.md.md`). * **Output Format:** Markdown. * **Language:** Chinese (as requested in the system prompt). * **Structure:** 1. Overall Summary, 2. Key Themes, 3. Impact Level, 4. Action Items. 2. **Analyze Page 1: `security.md`** * **Change:** Added a note regarding "Trust verification" when starting Claude Code in the home directory. * **Details:** If started in `~`, trust is session-only (not saved to disk), prompting re-acceptance every time. No setting to persist it. Suggestion: Start in a subdirectory to save trust per directory. * **Developer Relevance:** Developers often run tools from home or project roots. This explains a potentially annoying recurring prompt and provides a workaround. It affects security hygiene and UX. 3. **Analyze Page 2: `CHANGELOG.md.md`** * **Version:** 2.1.144. * **Categories of changes:** * *Background Sessions & Agent View:* `/resume` support, duration notifications, fixes for Windows/macOS, interaction fixes (Ctrl+C, scrolling), worktree isolation. * *Models & Usage:* `/model` is session-only now (default with 'd'), renamed "extra usage" to "usage credits". * *Stability & Performance:* Fixed startup hanging (API timeout), fixed terminal output corruption (self-healing), fixed garbled text, reduced glitches. * *MCP (Model Context Protocol):* Fixed pagination issues, image handling (SVG), file descriptor exhaustion in skill dirs. * *UX/UI:* Plugin discovery updates, AskUserQuestion notes field fix, better error messages. * *Platforms:* Specific fixes for macOS (Full Disk Access), Windows (scrolling, ghost characters), VS Code integration. * *Other:* Session title generation, skill loading, background side-queries, `claude mcp list` error reporting. 4. **Synthesize Key Themes (Mental Draft):** * *Background Sessions:* Heavy focus here (features + fixes). * *Stability/Reliability:* Terminal rendering, startup timeouts, crash fixes. * *Security/Trust:* New note in security.md + existing mechanisms. * *MCP & Plugins:* Robustness improvements. * *UX/QoL:* Model selection changes, renaming of commands. 5. **Draft Overall Summary (Chinese):** * Version 2.1.144 release with a focus on background session stability, terminal rendering fixes, and improved MCP/Plugin reliability. A specific security behavior regarding trust verification in the home directory was documented. 6. **Determine Impact Level:** * *High?* No breaking changes mentioned in the changelog. The `/model` behavior change might be noticeable but not breaking (since there's a 'd' key to set default). * *Medium?* Yes. Significant bug fixes (terminal corruption, startup hangs) improve daily usage. The trust verification behavior explains a specific user pain point. * *Reasoning:* High number of stability fixes and quality-of-life improvements. The change in `/model` behavior and the trust verification note are impactful for daily workflows. 7. **Draft Action Items (Chinese):** * Avoid running Claude in the home directory to prevent repeated trust prompts. * Note that `/model` changes only apply to the current session (use 'd' for default). * Update scripts/docs if using "extra usage" (now "usage credits"). * Consider upgrading to fix terminal rendering and startup hang issues. * Check MCP configurations if tools were missing (pagination fix). 8. **Refine the Output (Translating thoughts to the final Chinese Markdown structure):** * *Summary:* 版本 2.1.144 主要专注于增强后台会话的稳定性、修复终端渲染问题（如乱码和启动挂起）以及改进 MCP 和插件的可靠性。同时，文档中明确了在主目录启动时的信任验证行为。 * *Themes:* * 后台会话与代理视图：功能增强与大量稳定性修复。 * 稳定性与性能：解决终端乱码、启动超时、文件描述符耗尽等问题。 * 用户体验：模型选择逻辑变更、命令重命名。 * 生态支持：MCP 工具分页修复、SVG 图片处理、插件管理优化。 * *Impact:* Medium. * *Reasoning:* 虽然没有破坏性更新，但修复了大量影响日常使用的 Bug（特别是终端渲染和会话管理），并变更了模型设置的默认行为。主目录信任验证的说明解释了潜在的摩擦点。 * *Action Items:* * **目录习惯**：避免在主目录（`~`）直接启动 Claude Code，以免每次启动都需要重新确认信任授权；建议在项目子目录中启动。 * **模型选择**：注意 `/model` 命令现在仅更改当前会话模型，需按 `d` 键才能设置新会话的默认模型。 * **命令更新**：更新脚本或文档，将 `extra usage` 相关引用改为 `usage credits`。 * **环境检查**：如果使用 MCP 服务器，检查是否之前因分页问题导致工具缺失；升级后应能正常加载。 * **终端环境**：如果在 VS Code 或 Windows 终端遇到渲染问题，建议更新以利用自我修复功能。 9. **Final Review:** Does it meet all constraints? Yes. Concise? Yes. Insightful? Yes. Chinese? Yes. Markdown? Yes.
