1. **Analyze the Request:** * **Role:** World-class programmer, expert in developer tools/documentation. * **Input:** A single diff for `CHANGELOG.md.md` (version 2.1.153). * **Output Format:** Markdown (Concise, insightful, in Chinese). * **Structure:** 1. Overall Summary, 2. Key Themes, 3. Impact Level, 4. Action Items. 2. **Analyze the Content (Changelog 2.1.153):** * *New Features:* `skipLfs` for git/github sources, npm auto-update notice + doctor fixes, `COLUMNS`/`LINES` env vars for status line commands, autocomplete improvements for `claude agents`, PR column display changes. * *Core Logic Fixes:* * MCP (Model Context Protocol) fixes: Reconnect loops, regression with API gateway credentials vs. user tokens, subagent MCP server strict mode issues, strict-mcp-config behavior changes, background agents/macOS permissions. * Update mechanism: Windows PowerShell installer bug, `claude update` installing wrong channel version, Windows update rollback handling. * *Session/CLI Experience:* * Memory usage fix (transcript resume). * Stale daemon issues. * Stream-json mode hang fix. * File link clickable fix. * Help text rendering fix. * *Background Sessions (Agents) - Heavy Focus:* * `/bg` continuation behavior. * `/btw` responsiveness. * Temp file permission prompts. * Worktree recovery errors. * `EnterWorktree` availability. * `cmd+k` repaint. * IME window positioning (Windows). * Background color bleed. * Clipboard (`/copy`) issues in tmux. * Zombie session entries. * `/rename` banner update. * *IDE/VSCode Integration:* Process shutdown clean-up on Windows. * *Model Picker:* Saves default (`d` replaced by `s` for session-only). Keybinding rename. 3. **Synthesize Themes:** * **Stability & Bug Fixes:** Massive number of fixes, especially regarding background agents, MCP, and CLI behavior on different platforms (Windows/macOS). * **Developer Experience (DX):** Better autocomplete, status line scripts env vars, cleaner model picker. * **Background Agents:** This seems to be a major focus area of this release, fixing many edge cases (tmux, clipboard, IME, permissions). 4. **Determine Impact:** * *High:* Fixes memory usage, authentication leakage (API gateway regression), and update failures. The MCP fixes are critical for enterprise/power users. The background agent fixes significantly improve reliability of a core feature. * *Breaking:* Minor UI change (`d` vs `s` in model picker), and a keybinding rename instruction. Not a code-breaking change for most, but users need to be aware of the keybinding change if they customized it. 5. **Draft Action Items:** * Update Keybindings if customized (`modelPicker:setAsDefault` -> `modelPicker:thisSessionOnly`). * Run `/doctor` if you've had npm update issues. * Check `COLUMNS`/`LINES` usage in status line scripts (new opportunity). * Be aware of the new `skipLfs` option if using Git LFS. 6. **Translate and Refine (Chinese):** * *Summary:* Version 2.1.153 is a stability-focused update, primarily fixing issues with MCP servers, background agents, and platform-specific bugs (Windows/macOS). It also introduces improvements for CLI scripts and the model picker. * *Draft (CN):* v2.1.153 是一次以稳定性为核心的更新，重点修复了 MCP 服务器、后台代理以及平台特定的 Bug（尤其是 Windows 和 macOS），同时优化了 CLI 脚本支持和模型选择器体验。 * *Key Themes:* * Background Session Reliability (后台会话稳定性). * MCP & Authentication Security (MCP 与认证安全). * Cross-platform Compatibility (跨平台兼容性). * Developer Experience (DX) Enhancements (开发体验增强). * *Impact:* High. It fixes critical regressions (API gateway credentials, memory usage) and improves the reliability of a major feature (background agents). * *Draft (CN):* 高。修复了 API 网关凭据泄露的回归问题、严重的内存泄漏以及后台会话的多个异常，显著提升了系统稳定性和安全性。 * *Action Items:* * Rename keybinding if customized. * Review status line scripts for `COLUMNS`/`LINES`. * Use `skipLfs` if Git LFS is slowing down clones. * Run `/doctor` if install updates were failing. 7. **Final Polish (Markdown Structure):** * *Headings:* Use H2 or bold for sections. * *Tone:* Professional, concise. *(Self-Correction during drafting)*: Ensure I mention the specific API gateway credential leak fix. That's a security fix that matters. The change `d` -> `s` in the model picker is a UX change but requires action for users with custom keybindings. 8. **Final Output Generation** (matching the requested format).

1. **Understand the Goal**: The user wants a concise, insightful analysis of documentation changes provided as a diff. The output needs to be in Markdown, in Chinese, and focused on what matters to developers. The user provided diffs for 4 pages: `batch-processing.md`, `structured-outputs.md`, `web-search-tool.md`, and `mcp-connector.md`. 2. **Analyze the Diffs**: * **Page 1: `build-with-claude/batch-processing.md`** * *Changes*: * Changed "Any request" to "Almost any request" regarding batching. * Expanded the list of supported features: Added "Extended thinking" and changed "Any beta features" to "Most beta features". * **New Section**: Added a table explicitly listing *unsupported* parameters in batch requests: `stream: true`, `speed`, `store`/`previous_thread_event_id`, `cache_hint`/`context_hint`, `max_tokens: 0`, `research_preview_2026_02: "active"`. * **New Section**: "Server tools and the agentic loop". Explains that server tools (web search, web fetch, code execution, MCP connectors, advisor, tool search) work in batch. * *Specific detail*: Batch worker runs *more iterations* before pausing compared to sync requests. * *Specific detail*: Batch worker throttles `web_search` per org to prevent rate limit exhaustion. Retries are automatic. * Updated FAQ text to reflect the "nearly all features" and point to the unsupported list. * **Page 2: `build-with-claude/structured-outputs.md`** * *Changes*: * Added "Claude Haiku 4.5" to the list of models where structured outputs are GA on Vertex AI. * This is a minor availability update. * **Page 3: `agents-and-tools/tool-use/web-search-tool.md`** * *Changes*: * Added a paragraph about using Web Search in Batches API. * Mentions throttling per org to protect shared capacity. * Mentions price is the same. * Suggests typical workloads (enrichment, research, grounding). * **Page 4: `agents-and-tools/mcp-connector.md`** * *Changes*: * Added a section "Batch requests". * Confirms `mcp_servers` can be included in Batches API. * Mentions pricing is the same. 3. **Synthesize Themes**: * **Batch API Expansion**: The main theme is expanding the capabilities of the Message Batches API. * **Server Tools Support**: Explicitly confirming support for server tools (MCP, web search, etc.) in batches. * **Constraints & Clarifications**: Clarifying what *isn't* supported (streams, specific params) and how behavior differs (agentic loop iterations, rate limiting). * **Model Availability**: Minor update for Haiku 4.5 on Vertex AI. 4. **Determine Impact Level**: * *Low*: No breaking changes for existing code (unless someone was trying to use `stream: true` in batches and it was silently failing or unclear, but usually that's a validation error). It adds new capabilities and clarifies limitations. * *Medium*: Significant enhancement for developers using batch processing with agentic workflows (Server tools, MCP). The throttling info is important for performance expectations. * *Reasoning*: It enables more complex workflows in batch mode (agentic loops) but doesn't break existing synchronous flows. The clarification on unsupported params prevents confusion. 5. **Draft Action Items**: * Review unsupported parameters in Batch API if planning complex batch jobs. * Take advantage of server tools (MCP, Web Search) in batch jobs for data enrichment. * Monitor batch job times if using extensive Web Search due to throttling. * Update code/docs if relying on `research_preview_2026_02` or specific params in batches. 6. **Draft the Response (in Chinese)**: * *Overall Summary*: Documentation updates primarily focus on expanding and clarifying the capabilities of the Message Batches API, specifically enabling support for server tools (MCP, Web Search) and detailing unsupported parameters and rate limiting behaviors. * *Key Themes*: * Enhanced Batch API Support for Server Tools: Explicitly confirmed that server tools (Web Search, MCP, Code Execution, etc.) are supported. * Clarification of Limitations: Added a clear table of unsupported parameters (e.g., `stream`, `speed`, `cache_hint`). * Performance and Rate Limiting: Noted that the batch agentic loop runs longer before pausing, and web search is throttled per organization. * Model Availability: Added Structured Outputs support for Claude Haiku 4.5 on Vertex AI. * *Impact Level*: Medium (Functional enhancement and clarification). * *Reasoning*: While not a breaking change, it significantly expands what developers can do with batch processing (agentic workflows) and clears up potential confusion about compatibility, requiring developers to adjust their expectations regarding throttling and specific parameter exclusions. * *Action Items*: * Check the updated list of unsupported parameters before designing complex batch workflows. * Leverage the newly confirmed support for MCP and Web Search tools in batch jobs for high-volume processing. * Account for potential throttling delays when using Web Search in large batches. * Update documentation or code if previously assuming all beta features or specific routing hints worked in batch mode. 7. **Review and Refine**: * Ensure tone is professional and concise. * Check against the diffs again. * The "more iterations per turn" point is a specific technical detail worth mentioning in themes or action items? Probably themes under "Behavioral changes". * Make sure the Chinese translation is natural. *Refining the "Overall Summary"*: 此次文档更新主要围绕消息批处理 API（Message Batches API）的功能扩展与限制澄清，特别是明确了服务端工具和 MCP 在批处理中的支持情况，以及新增的参数限制和速率控制说明。 *Refining "Key Themes"*: * 批处理 API 能力增强：明确了支持 MCP 连接器、Web 搜索等服务端工具。 * 限制条件清单化：新增表格详细列出不支持的参数（如 `stream`, `speed` 等）。 * 行为差异说明：批处理中的代理循环会有更多迭代次数，且 Web 搜索受限于组织级别的速率限制。 * 模型可用性微调：在 Vertex AI 上新增了对 Claude Haiku 4.5 结构化输出的支持。 *Refining "Impact"*: Medium. * Reasoning: 新增了对复杂代理工作流在批处理中的支持，这对开发者非常有用，但也引入了速率限制这一潜在的性能瓶颈因素，需要开发者关注。 *Refining "Action Items"*: * 重新审视现有的批处理任务，确保未使用不支持的参数（如 `stream` 或 `cache_hint`）。 * 利用新增的 MCP 和 Web Search 支持功能，将代理式任务迁移至批处理以降低成本或提高吞吐量。 * 在设计大规模 Web Search 批处理任务时，预留额外时间以应对自动重试带来的延迟。 * 若使用了 `research_preview_2026_02` 等标记，需调整批处理请求配置。 8. **Final Polish**: Looks good. Formatting matches the request.

1. **Understand the Goal:** The user wants a concise, insightful analysis of documentation changes for 11 pages. The output must be in markdown, in Chinese, focusing on what matters to developers. 2. **Analyze the Changes (Page by Page):** * **cli-reference.md:** * Change: `--fallback-model` description updated. * Detail: Added "or not available, for example a retired model". * Significance: Clarifies that fallback works for more than just overload (e.g., deprecated models). * **headless.md:** * Change: Example in Note updated. * Detail: Changed `/commit` to `/code-review`. * Significance: Likely a typo fix or reflecting a change in default/bundled skills. Minor documentation update. * **hooks.md, hooks-guide.md, plugins-reference.md:** * Change: Added `MessageDisplay` event to the list of available hook events. * Detail: "While assistant message text is displayed".

Better tracking of entry points and MCP tool usage. * **plugin-marketplaces.md:** * Change: `claude plugin marketplace remove` command updated. * Detail: Added `--scope` option (`user`, `project`, `local`). Updated warning text to be more specific about "last remaining scope". * Significance: Finer control over plugin management. Prevents accidental removals across scopes. * **settings.md:** * Change: Added `pluginSuggestionMarketplaces` setting. * Detail: Managed settings only. Allows specifying marketplaces for contextual plugin suggestions. * Significance: Enterprise/Managed settings feature for controlling plugin discovery. * **skills.md, slash-commands.md:** * Changes: 1. `allowed-tools` description updated: Added support for comma-separated strings (in addition to space-separated or YAML list). 2. New field: `disallowed-tools`. Allows specifying tools to explicitly *exclude* during skill execution (e.g., preventing `AskUserQuestion` in background loops). Format same as `allowed-tools`. * Significance: Enhanced safety and flexibility in skill/command definition. Negative permissions (blacklisting) added. 3. **Synthesize and Structure:** * **Overall Summary:** The updates focus on enhancing observability (telemetry/tracing), improving tool management (skills/plugins), and refining fallback mechanisms. * **Key Themes:** * *Observability:* New OTEL attributes (entrypoint, MCP details) and tracing context propagation control. * *Tool/Skill Control:* New `disallowed-tools` field for skills, comma support in `allowed-tools`, new `MessageDisplay` hook. * *Plugin Management:* Scoped removal of marketplaces and managed marketplace suggestions. * *Usability:* Vim mode keybinding, clarified fallback model behavior. * **Impact Level:** Medium. Mostly additive features and refinements. No breaking changes explicitly mentioned (except maybe existing behavior clarifications), but significantly enhances developer control and visibility. * **Action Items:** * Update telemetry dashboards to utilize new entrypoint and MCP attributes. * Review skills to potentially utilize `disallowed-tools` for safer background automation. * Adjust plugin marketplace scripts to handle the new `--scope` option if needed. * Update hooks implementations if real-time message handling is desired. * Review tracing configuration if using custom proxies (`CLAUDE_CODE_PROPAGATE_TRACEPARENT`). 4. **Drafting the Response (in Chinese):** * *Summary:* 此次更新主要增强了可观测性（遥测与追踪能力）、改进了工具/技能管理的控制粒度，并优化了插件市场及 CLI 的易用性。 * *Themes:* * **可观测性增强**: 新增 `app.entrypoint` 和 MCP 相关 (`mcp_server.name`, `mcp_tool.name`) 指标属性；支持通过环境变量更灵活地控制 `traceparent` 的传播。 * **技能与钩子系统**: 技能定义新增 `disallowed-tools` 字段以实现工具黑名单；Hook 系统新增 `MessageDisplay` 事件用于实时响应消息流。 * **插件与市场管理**: 支持按作用域移除插件市场 (`--scope`)；新增受管设置 `pluginSuggestionMarketplaces`。 * **CLI 体验**: 明确了 `--fallback-model` 对退役模型的支持；Vim 模式新增反向搜索快捷键。 * *Impact:* **Medium** (中等)。主要是功能增强和文档更新，提供了更细粒度的控制和更深入的监控能力，未发现破坏性变更。 * *Action Items:* * 利用新增的 MCP 和入口点属性更新监控仪表盘，以细化成本和性能分析。 * 审查并更新自动化的 Skill 配置，使用 `disallowed-tools` 提升后台运行的安全性。 * 若使用自定义代理或需要分布式追踪，检查并配置 `CLAUDE_CODE_PROPAGATE_TRACEPARENT`。 * 插件管理脚本需适配 `claude plugin marketplace remove` 的新 `--scope` 选项。 * 评估在 Hook 中使用新的 `MessageDisplay` 事件以实现实时 UI 反馈。 5. **Final Polish:** Ensure markdown format is correct and tone is professional/insightful. (Self-correction: Make sure to mention comma-separated support for allowed-tools as a small but handy UX improvement). 6. **Final Output Generation.** (Proceed to generate output based on step 4).

用户想要一份针对文档变更 `interactive-mode.md` 的简洁、深刻的分析。 格式要求使用 Markdown。 用户要求用中文回复。 具体内容关于 `/btw` 侧边问题的更新。 **变更分析：** 1. **原始内容：** * 侧边问题在 Claude 处理时可用。 * 无工具访问权限。 * 单次响应，覆盖层中无后续轮次。建议使用普通提示词进行来回交流。 * 低成本。 * 按 Space、Enter 或 Escape 关闭。 2. **新内容：** * 关于“单次响应”的更新：它说覆盖层中没有后续轮次，*但*你可以使用 `f` 将其分支到自己的会话中以继续。 * **视觉历史记录**：早期侧边问题会在当前答案上方显示为一个变暗的列表。它们不会进入对话历史记录，但会在覆盖层中保持可见，直到被清除。 * **键盘交互表**：现在有一个键盘快捷键表： * `Space`、`Enter`、`Escape`：关闭。 * `Up` / `Down`：滚动答案。 * `f`：分支到新会话。继承父级 + 问答。完整工具访问。原始会话保留在 `/resume` 下。*仅限本地会话*。 * `x`：清除早期侧边问题列表。 * 比较注释：仍然是子代理的反向操作。 **综合分析（按要求用中文）：** 1. **Overall Summary (整体概要):** 文档更新了 `/btw` 命令的功能，引入了会话分支 (`f`)、侧边问题历史记录显示以及新的键盘快捷键（如滚动和清除历史），显著增强了交互体验。 2. **Key Themes (关键主题):** * **增强的交互性**：通过 `f` 键实现了从侧边问题无缝切换到全功能会话的能力。 * **UI/UX 改进**：增加了侧边问题历史记录的可视化显示以及滚动 (`Up`/`Down`) 和清理 (`x`) 功能。 * **工作流集成**：明确了侧边问题与主会话的关系，特别是如何利用分支功能继续深入讨论。 3. **Impact Level (影响级别):** * **级别**：Medium (中等) * **原因**：这是一个功能增强，不是破坏性更改。它为现有的工具提供了新的工作流（分支），提高了开发人员使用 `/btw` 进行上下文查询的效率，但核心行为（无工具访问、低延迟）保持不变。 4. **Action Items (行动建议):** * 尝试使用 `f` 键将重要的侧边问题分支到新会话中继续处理。 * 利用 `x` 键清理累积的侧边问题列表，保持界面整洁。 * 在查看长答案时使用 `Up` / `Down` 键进行滚动。 * 注意 `f` 键功能仅在本地会话中可用。 **格式检查：** Markdown 格式？是。 中文语言？是。 简洁？是。 起草回复。
