1. **Analyze the Request:** * **Role:** World-class programmer, expert in developer tools. * **Task:** Analyze documentation changes (9 pages), summarize changes, explain why it matters. * **Format:** Markdown, Chinese, concise, insightful. * **Specific Sections:** Overall Summary, Key Themes, Impact Level, Action Items. 2. **Scan and Process the Diff Files:** * **`checkpointing.md` (+3/-0):** * *Change:* Added a `<Note>` clarifying the difference between "Summarize" (context compression) and "fork" (branching). * *Developer Relevance:* Clarifies workflow choices between preserving context vs. branching. * **`cli-reference.md` (+10/-6):** * *Change:* Updated the `--agents` flag documentation table. * *New Fields:* `disallowedTools` (explicit denial), `skills` (preload skills), `mcpServers` (specific MCP servers), `maxTurns` (limit iterations). * *Developer Relevance:* Provides much finer-grained control over custom subagents via CLI (deny tools, limit loops, specific integrations). * **`hooks.md` (+77/-32):** * *Change:* New hook events (`TeammateIdle`, `TaskCompleted`) added to the lifecycle table and diagrams. * *Change:* Updated matchers list to include the new events. * *Developer Relevance:* Extends the hook system to support agent teams workflows (idle states, task completion), allowing more granular automation and monitoring of complex agent behaviors. * **`hooks-guide.md` (+26/-24):** * *Change:* Consistent with `hooks.md` (new events added to tables). * *Change:* Added new SessionEnd matcher value (`bypass_permissions_disabled`). * *Developer Relevance:* Reinforces the new agent team capabilities and specific exit condition handling. * **`memory.md` (+36/-3):** * *Change:* Major update to memory documentation. * *Concept:* Introduced "Auto memory" (automatic notes by Claude) vs. "CLAUDE.md files" (manual instructions). * *Details:* Auto memory location (`~/.claude/projects/<project>/memory/`), limit (first 200 lines of `MEMORY.md`), environment variable control (`CLAUDE_CODE_DISABLE_AUTO_MEMORY`). * *Developer Relevance:* Developers need to understand that Claude now "writes its own notes" and how to manage/opt-in/opt-out of this feature. * **`plugins-reference.md` (+2/-0):** * *Change:* Added `TeammateIdle` and `TaskCompleted` to plugin hook events. * *Developer Relevance:* Ensures plugin developers can hook into the new agent team lifecycle. * **`settings.md` (+2/-1):** * *Change 1:* Added `CLAUDE_CODE_DISABLE_AUTO_MEMORY` environment variable. * *Change 2:* Updated `SLASH_COMMAND_TOOL_CHAR_BUDGET` description to mention dynamic scaling (2% of context window, fallback 16k). * *Developer Relevance:* Fine-tuning control over auto memory and skill metadata limits. * **`skills.md` (+5/-2):** * *Change 1:* Skills from `--add-dir` are auto-loaded with live detection. * *Change 2:* Updated char budget explanation (dynamic 2%). * *Developer Relevance:* Improved workflow for external skill management and better context management. * **`sub-agents.md` (+33/-21):** * *Change 1:* Updated `--agents` flag description to list new fields (`skills`, `mcpServers`, `maxTurns`). * *Change 2:* Updated Subagent frontmatter table. Added `maxTurns`, `mcpServers`. Added `delegate` to `permissionMode`. * *Change 3:* Added section "Restrict which subagents can be spawned". * *Developer Relevance:* Enhanced control over agent hierarchy, resource limits, and permissions. 3. **Synthesize Key Themes:** * **Agent Teams / Multi-Agent Logic:** The addition of `TeammateIdle` and `TaskCompleted` hooks across multiple files points to a significant strengthening of the "Agent Teams" functionality. * **Auto Memory:** Introduction of a new automatic memory system where Claude learns and persists notes autonomously. * **Finer-Grained Agent Control:** New configuration options for subagents (`maxTurns`, `disallowedTools`, `mcpServers`, `skills`). * **Configuration & Limits:** Dynamic context budgeting for skills and explicit opt-in/out flags for new features. 4. **Drafting the Response (in Chinese):** * *Overall Summary:* 本次更新引入了“自动记忆”功能，增强了 Agent 团队的生命周期管理，并显著细化了 Sub-agents 的配置控制能力。 * *Key Themes:* * **自动记忆:** Claude 现在可以自动记录项目模式和上下文笔记。 * **Agent 团队钩子:** 新增 `TeammateIdle` 和 `TaskCompleted` 事件，支持更复杂的多代理工作流。 * **Sub-agent 增强:** 新增 `maxTurns`、`mcpServers` 等字段，提供更细粒度的权限和资源限制。 * **配置优化:** 技能描述的字符预算现在动态调整（上下文的 2%）。 * *Impact Level:* High. Auto memory changes how state is persisted, and new hooks/events significantly expand automation capabilities for agent teams. * *Action Items:* * Check if Auto Memory behavior fits your workflow (opt-in/out via env var). * Review new hooks if you automate Claude Code workflows. * Update agent configs to use `maxTurns` to prevent infinite loops. * Adjust skills management now that external directories support live reload. 5. **Refining the Output (Self-Correction during drafting):** * Make sure to mention the specific environment variable `CLAUDE_CODE_DISABLE_AUTO_MEMORY`. * Clarify the distinction between `fork` and `summarize` as that's a specific user-facing fix. * Ensure the "High" impact is justified (Auto memory is a paradigm shift for context management). 6. **Final Polish (Markdown Format):** (Proceeding to generate the output based on the above thought process.) * *Summary:* 这次更新引入了“自动记忆”机制，让 Claude 能够自主保存项目上下文；同时新增了针对 Agent 团队的生命周期钩子，并大幅增强了 Sub-agent 的配置颗粒度。 * *Themes:* 1. **智能上下文管理**：新增 Auto Memory。 2. **Agent 团队生态扩展**：新增钩子事件。 3. **精细化代理控制**：Sub-agent 新增限制工具、最大轮次等字段。 4. **配置与性能调优**：技能字符预算动态化，支持外部目录热加载。 * *Impact:* **High**。Auto Memory 改变了状态持久化的方式，新钩子和 Agent 配置选项为构建复杂自动化工作流提供了必要的基础设施。 * *Action Items:* * 配置 `CLAUDE_CODE_DISABLE_AUTO_MEMORY` 以控制自动记忆的开启/关闭。 * 利用 `maxTurns` 防止 Sub-agent 陷入无限循环。 * 更新 Hook 脚本以处理 `TeammateIdle` 和 `TaskCompleted` 事件。 * 利用 `--add-dir` 管理外部技能目录，体验实时更新。 7. **Final Review against constraints:** Concise? Yes. Insightful? Yes. Chinese? Yes. Markdown? Yes.

1. **Understand the Goal:** The user wants a concise, insightful analysis of documentation changes across 8 pages. The persona is a world-class programmer/developer tools expert. The output must be in Markdown and Chinese. 2. **Analyze the Input Data (Diff Chunks):** * **Page 1: `api/client-sdks.md` (+158 / -48)** * *Change:* Major restructure. Moved from a list of GitHub links and manual install instructions to a UI-heavy "CardGroup" layout with tabs. * *New Content:* Added "Quick start" code snippets for *all* languages (Python, TS, Java, Go, Ruby, C#, PHP). Added specific language details (e.g., Python: Sync/async, Pydantic; Java: Builder pattern). * *Model Update:* Used `claude-opus-4-6` in examples. * *Significance:* Centralized SDK info, improved onboarding with code samples. * **Page 2: `build-with-claude/vision.md` (+60 / -17)** * *Change:* Added code examples for Go, Ruby, C#, PHP for downloading/encoding images. * *Model Update:* Updated Java examples to use `Model.CLAUDE_OPUS_4_6` (from `CLAUDE_SONNET_4_5_LATEST`). * *Text Tweaks:* "our API" -> "the API", "we recommend" -> "consider/prefer" (tone adjustment). * *Significance:* Multi-language support expansion in examples. * **Page 3: `build-with-claude/batch-processing.md` (+83 / -0)** * *Change:* Added batch processing code examples for Go, Ruby, C#, PHP. * *Model Update:* Used `claude-opus-4-6`. * *Significance:* Closing the gap in documentation for non-Python/TS SDKs. * **Page 4: `build-with-claude/citations.md` (+1 / -1)** * *Change:* Minimal. Changed model constant `CLAUDE_SONNET_4_20250514` to `CLAUDE_OPUS_4_6`. * *Significance:* Keeping examples consistent with the latest model. * **Page 5: `build-with-claude/structured-outputs.md` (+151 / -6)** * *Change:* Added huge code blocks for Java, Go, Ruby, C#, PHP showing `json_schema` usage. * *Feature Note:* Expanded documentation on native schema definitions (Pydantic/Zod -> added Java classes, Ruby BaseModel). * *Significance:* Demonstrates structured outputs parity across all major SDKs. * **Page 6: `build-with-claude/files.md` (+121 / -0)** * *Change:* Added code examples for uploading files and using them in messages for Java, Go, Ruby, C#, PHP. * *Significance:* Files API is now fully documented for all SDKs. * **Page 7: `build-with-claude/claude-on-amazon-bedrock.md` (+92 / -3)** * *Change:* Added installation instructions (Tabs) for Java and Go Bedrock SDKs. * *Change:* Added "Quickstart" and "Regional endpoints" code examples for Java and Go (using `BedrockBackend` and `bedrock` package). * *Significance:* Official support for Java and Go on Bedrock via SDKs. * **Page 8: `build-with-claude/claude-on-vertex-ai.md` (+95 / -2)** * *Change:* Similar to Bedrock. Added installation for Java and Go. * *Change:* Added usage examples (standard and regional) for Java and Go. * *Significance:* Official support for Java and Go on Vertex AI via SDKs. 3. **Synthesize Themes:** * **Multi-language SDK Parity:** The biggest change is the explosion of code examples for **Java, Go, Ruby, C#, and PHP**. Previously, docs were very Python/TS-centric. Now they cover the full suite. * **New Model Reference (`claude-opus-4-6`):** Almost every code block update references this new model. * **Platform Integration:** Java and Go SDKs are now explicitly documented for Bedrock and Vertex AI. * **Feature Consistency:** Structured outputs, Files API, Batch processing, and Vision now have working examples across *all* languages. 4. **Determine Impact:** * *Level:* **Medium to High**. * *Reasoning:* While not "breaking" (APIs didn't change), it significantly improves the developer experience (DX) for non-Python/TS developers. It signals that these SDKs are "first-class citizens" now. The mention of `claude-opus-4-6` suggests a new model release context. 5. **Formulate Action Items:** * Update SDKs if using Java/Go/Ruby/C#/PHP on Bedrock/Vertex (new packages/modules might be available). * Test with the new `claude-opus-4-6` model. * Review the new multi-language examples for patterns to adopt (especially for Structured Outputs/Files API). 6. **Drafting the Response (in Chinese):** * *Summary:* Documentation overhaul focusing on full SDK coverage (Java, Go, Ruby, C#, PHP) and introducing `claude-opus-4-6`. * *Themes:* * Multi-language parity (Java/Go/etc.). * Model updates (Opus 4.6). * Platform support (Bedrock/Vertex). * *Impact:* Medium-High. Huge DX improvement. * *Action Items:* * Check new model. * Upgrade SDKs for Bedrock/Vertex integration in Java/Go. * Explore Structured Outputs in your specific language. 7. **Refining the Output (Self-Correction during drafting):** * Make sure to mention specific features like Structured Outputs and Files API got the new code examples. * Ensure the tone is professional and "world-class". 8. **Final Polish (Markdown):** ```markdown 1. Overall Summary: ... 2. Key Themes: ... 3. Impact: ... 4. Action Items: ... ``` (Proceeding to generate the response based on these points.)

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** Three diffs (`amazon-bedrock.md`, `checkpointing.md`, `interactive-mode.md`). * **Output Format:** Markdown, specific sections (Overall Summary, Key Themes, Impact Level, Action Items). * **Language:** Chinese (as requested: "请用中文回复"). * **Focus:** Developer-centric, concise, insightful. 2. **Analyze the Diffs:** * **`amazon-bedrock.md` (-8 lines):** * *Change:* Removed section "5. Output token configuration" (environment variables `CLAUDE_CODE_MAX_OUTPUT_TOKENS` and `MAX_THINKING_TOKENS` and their explanations). * *Implication:* The specific token limits recommended for Bedrock are no longer needed in the docs. Maybe the tool handles this automatically now, or the defaults are sufficient, or it was a transient configuration step. * **`checkpointing.md` (+20 / -9):** * *Change:* Updated description and functionality of the "rewind" feature. * *New:* Added "Summarize from here" to the rewind menu. * *Details:* You can now compact the conversation from a specific point forward without changing files. This frees up context window space. It distinguishes "Restore" vs. "Summarize". * *UI Flow:* Select prompt -> Action (Restore code/conv/both, Summarize, etc.). After restoring, prompt is put back in input field. * *Use Cases:* Added "Freeing context space". * **`interactive-mode.md` (+2 / -2):** * *Change:* Updated description for the `Esc + Esc` shortcut and the `/rewind` command to reflect the new "Summarize from here" functionality added in `checkpointing.md`. 3. **Synthesize Themes:** * *Theme 1: Context Management.* The major new feature is the ability to summarize parts of the conversation from the rewind menu to free up context tokens. * *Theme 2: Simplification/UX Improvements.* Removing manual token config for Bedrock suggests the product is getting easier to use (less manual tuning). * *Theme 3: Workflow Enhancement.* Rewind is no longer just about "undoing"; it's also about "optimizing" (via summarization). 4. **Determine Impact:** * *Bedrock change:* Low impact (removal of manual config usually means better defaults or auto-handling). * *Checkpointing/Rewind change:* Medium/High impact for users dealing with long contexts or debugging sessions. It addresses a real pain point (running out of context) in a smarter way than just a global `/compact`. * *Overall:* **Medium** (Feature enhancement + Cleanup). 5. **Draft Action Items:** * Developers can remove those specific Bedrock env vars if they set them manually (check if they are defaults). * Developers should learn the new "Summarize from here" workflow to manage long sessions. * Update any internal documentation or scripts that reference the removed Bedrock tokens (if any). 6. **Translate to Chinese & Format:** * *Summary:* 文档主要优化了上下文管理功能，在回滚机制中增加了“总结”选项以释放 Token 空间，同时移除了针对 Amazon Bedrock 的手动 Token 配置建议。 * *Themes:* * 增强的会话管理：回滚菜单新增“从此处总结”功能，允许选择性压缩对话历史以节省上下文。 * 配置简化：移除了 Bedrock 特定的输出 Token 配置指南，表明工具可能已自动化处理这些限制。 * 用户体验提升：区分了“恢复状态”和“压缩历史”，为处理长对话提供了更精细的控制。 * *Impact:* **Medium** (中等)。新增功能显著改善了长会话的管理能力，而配置项的移除降低了使用门槛。 * *Action Items:* * 探索新的 `/rewind` 菜单中的“Summarize from here”功能，以管理长对话的上下文占用。 * 如果之前手动配置了 `CLAUDE_CODE_MAX_OUTPUT_TOKENS` 或 `MAX_THINKING_TOKENS`，可以考虑移除并依赖默认设置。 * 更新团队内部关于 Claude Code 工作流程的知识库，特别是关于会话回滚和优化的部分。 7. **Review and Refine:** * Ensure the tone is professional and "world-class programmer" style. * Check for accuracy based on the diffs. (e.g., Bedrock removal is definitely a simplification/supersedence). * Structure matches the prompt requirements. 8. **Final Output Generation** (matches the drafted content).

1. **Analyze the Request**: * **Role**: World-class programmer, expert in dev tools/documentation. * **Task**: Analyze a specific batch of documentation changes (only one file: `CHANGELOG.md.md`). * **Format**: Markdown, specific sections (Summary, Key Themes, Impact, Action Items). * **Language**: Chinese. 2. **Analyze the Input**: * **File**: `CHANGELOG.md.md`. * **Diff**: Added version `2.1.34` with two bug fixes. * Fix 1: "Fixed a crash when agent teams setting changed between renders". (Fixes a crash related to state changes in agent teams during re-rendering). * Fix 2: "Fixed a bug where commands excluded from sandboxing... could bypass the Bash ask permission rule when `autoAllowBashIfSandboxed` was enabled". (Fixes a security/logic bypass regarding sandbox exclusions and Bash permissions). 3. **Drafting the Content (Internal Monologue & Translation)**: * **Overall Summary**: The changelog update (v2.1.34) addresses two specific bugs: a crash related to agent teams and a security/permissions bypass involving sandboxing and Bash commands. * *Chinese*: 本次更新（v2.1.34）修复了两个关键 Bug：一个是代理团队设置变更时导致的崩溃，另一个涉及沙箱绕过 Bash 询问权限的漏洞。 * **Key Themes**: * Stability (crash fix). * Security/Permissions (Sandboxing, Bash execution rules). * *Chinese*: * 稳定性增强：修复了渲染过程中的崩溃问题。 * 安全与权限逻辑：修复了沙箱配置与 Bash 权限规则之间的逻辑冲突，确保权限检查的一致性。 * **Impact Level**: * The crash fix is Medium for those experiencing it. * The sandbox bypass is High (security implication), potentially allowing unauthorized command execution if specific settings were mixed. * *Decision*: High. Bypassing a permission rule is a big deal, even if it required specific flags (`autoAllowBashIfSandboxed`). * *Reasoning*: One fix prevents a crash (stability), and the other prevents a security permission bypass (safety/expectations). * *Chinese*: High (高影响)。 * *Reasoning*: 其中一个修复涉及沙箱绕过 Bash 权限询问的潜在安全风险，这违背了用户对安全策略的预期；另一个修复则提升了应用的稳定性。 * **Action Items for Developers**: * Upgrade to v2.1.34. * Review sandbox settings (`sandbox.excludedCommands`, `dangerouslyDisableSandbox`, `autoAllowBashIfSandboxed`) if relying on strict Bash permissions. * *Chinese*: * 升级至 v2.1.34 版本以修复崩溃和沙箱绕过问题。 * 如果使用了 `autoAllowBashIfSandboxed` 配合沙箱排除列表，请重新验证之前的 Bash 权限请求行为是否符合预期。 * 检查日志以确保代理团队设置变更不再导致异常。 4. **Refining the Output**: * *Reviewing against constraints*: Concise? Yes. Insightful? Yes. Developer-focused? Yes. Chinese? Yes. * *Final Polish*: * Summary: Keep it tight. * Themes: Use "稳定性" and "安全性/权限控制". * Impact: High due to the bypass bug. * Actions: Upgrade, verify config. 5. **Final Output Generation** (similar to the drafted Chinese sections). * *Self-Correction during drafting*: Wait, the filename is `CHANGELOG.md.md`. That's a bit odd (double extension), but usually implies it's the changelog file. I should focus on the content. The fix regarding "sandbox.excludedCommands" bypassing "Bash ask permission" is definitely the most important part for a developer caring about security. 6. **Construct Final Response**.
