Changes on 2026-03-19

1. **Analyze the Request**: * **Role**: World-class programmer, documentation expert. * **Task**: Analyze documentation changes (single batch). * **Input**: 9 markdown files with diffs. * **Output Format**: Markdown, Concise, Insightful, Chinese language. * **Structure**: Overall Summary, Key Themes, Impact Level, Action Items. 2. **Analyze the Diffs (Page by Page)**: * **`discover-plugins.md`**: * Change: "reloads commands, skills..." -> "reloads plugins, skills...". * Meaning: `/reload-plugins` output text updated. The count is now "plugins" instead of "commands". Slight wording adjustment, but functionality seems the same (counts what was reloaded). * **`hooks.md`**: * Change: `SessionEnd` reasons table adds `resume`. * Change: Description table adds `resume` (Session switched via interactive `/resume`). * Change: Timeout text mentions "switching sessions via interactive `/resume`". * Meaning: The interactive `/resume` command now triggers `SessionEnd` hooks (and presumably `SessionStart` hooks on resumption). This is a behavioral change for hook developers. * **`hooks-guide.md`**: * Change: `SessionEnd` reasons table adds `resume`. * Meaning: Consistency update to match `hooks.md`. * **`model-config.md`**: * Change: Added bullet point about "Skill and subagent frontmatter" overriding effort level. * Change: Precedence text updated to include frontmatter overrides (Env > Config > Frontmatter > Model default). * Meaning: You can now set `effort` in skill/subagent frontmatter. This is a new feature for fine-tuning model behavior per skill/agent. * **`plugin-marketplaces.md`**: * Change: Added `knowledge-work-plugins` to reserved names list. * Meaning: Policy update to prevent namespace squatting/impersonation for a new official marketplace. * **`plugins.md`**: * Change: `/reload-plugins` description text updated (commands -> plugins). Consistency with `discover-plugins.md`. * **`settings.md`**: * Change: "seven marketplace source types" -> "multiple marketplace source types". * Meaning: Documentation softening. Likely because the number changed or they don't want to maintain a specific count in the text. * **`statusline.md`**: * Change: Added section "Workspace trust required". * Meaning: Statusline custom scripts require workspace trust. If not trusted, it shows a specific message. This clarifies behavior for users writing statusline scripts. * **`sub-agents.md`**: * Change: "Enable" (memory) -> "User scope" (memory). UI text update. * Change: `--agents` flag list adds `memory`, `effort`, `background`, `isolation`. * Change: Table adds `effort` and `isolation` rows. * Meaning: New JSON arguments for `--agents` flag and new frontmatter options. Specifically `effort` and `isolation` are new features. 3. **Synthesize and Categorize**: * **Theme 1: `/resume` behavior refinement.** Hooks now fire when switching sessions via interactive `/resume`. * **Theme 2: Effort Level granularity.** `effort` can now be set in skill/subagent frontmatter or CLI flags. * **Theme 3: Subagent features expansion.** Subagents now support `isolation` (git worktree) and `effort` configuration via frontmatter/CLI. * **Theme 4: Documentation clean-up/Policies.** Reserved names, statusline trust, and text consistency (reload plugins). 4. **Draft the Analysis (in Chinese)**: * *Summary*: 本次更新主要集中在增强 `/resume` 的生命周期钩子支持、扩展子代理和技能的 `effort`（努力程度）配置能力，以及明确了状态栏脚本的信任要求。 * *Key Themes*: * **生命周期钩子扩展**：`SessionEnd` 现在会在通过交互式 `/resume` 切换会话时触发（原因标识为 `resume`），这意味着切换会话也会执行清理逻辑。 * **配置粒度细化**：引入了在技能和子代理的 frontmatter 中设置 `effort` 级别的能力，允许更精细地控制特定组件的资源消耗或模型行为。 * **子代理功能增强**：通过 CLI `--agents` 标志或 frontmatter，子代理现在支持 `isolation`（Git worktree 隔离）和 `effort` 设置。 * **安全与信任**：自定义状态栏脚本现在明确要求工作区信任，否则会显示跳过提示。 * *Impact Level*: Medium. (Behavioral changes in hooks affect existing scripts, new configuration options are additive but important for advanced users). * *Action Items*: * 检查 `SessionEnd` 钩子，确保它们能正确处理 `resume` 事件。 * 利用新的 frontmatter `effort` 字段优化特定技能或子代理的性能。 * 如果使用 `--agents` 标志或定义子代理，考虑利用新增的 `isolation` 和 `effort` 选项。 * 若状态栏未显示，请检查是否授予了工作区信任。 5. **Refine Language (Professional & Concise)**: * Translate concepts accurately: * "Hooks" -> 钩子 * "Frontmatter" -> Frontmatter (or 前置元数据, usually kept as frontmatter in dev context) * "Sub-agents" -> 子代理 * "Workspace trust" -> 工作区信任 * "Isolation" -> 隔离 (Git worktree context) 6. **Final Output Generation**: (Proceeding to generate the markdown response). * *Self-Correction during drafting*: Make sure to highlight the `resume` hook change as it's a subtle behavioral shift. Make sure to link the `effort` config in `model-config` and `sub-agents` as a cohesive feature addition. 7. **Final Polish**: * Summary: Concise. * Themes: Clear bullets. * Impact: Medium with solid reasoning. * Action Items: actionable. *(Self-Correction on `discover-plugins.md` and `plugins.md` change)*: It's just a text change from "commands" to "plugins" in the description of what is reloaded. Not huge, but indicates internal grouping shift. I will group it under "Doc refinements" rather than a major theme, or omit it if space is tight (but request asks for "what changed"). I'll focus on the functional changes. *(Check `sub-agents.md` diff again)*: - `--agents` flag now accepts `memory`, `effort`, `background`, `isolation`. - Frontmatter table adds `effort`, `isolation`. - `memory` config changed UI text "Enable" -> "User scope". This confirms the expansion of subagent capabilities. *(Check `hooks.md` diff again)*: `SessionEnd` gets `resume`. Timeout text mentions `/resume`. This is a concrete functional change for hook developers. *(Check `statusline.md`)*: Workspace trust required section added. This is a troubleshooting/behavior clarification. *Conclusion*: Medium impact is appropriate. *Language Check*: Chinese. Let's write it out.

1. **Analyze the Request:** * **Role:** World-class programmer. * **Task:** Analyze documentation changes (single batch) and summarize. * **Output:** Concise, insightful analysis in Markdown format. * **Language:** Chinese. * **Focus:** What matters to developers. * **Input:** Diffs for 10 pages. 2. **Review the Diffs (Page by Page):** * **Page: `get-started.md`** * *Change:* Java SDK version updated from `2.15.0` to `2.18.0` (Gradle and Maven). * *Relevance:* Dependency update. * **Page: `api/client-sdks.md`** * *Change 1:* Java SDK version updated from `2.15.0` to `2.18.0`. * *Change 2:* Go minimum version requirement updated from `1.22+` to `1.23+`. * *Relevance:* Dependency updates, environment requirement changes. * **Page: `build-with-claude/vision.md`** * *Change:* Added `cd "$(mktemp -d)"` and `curl ...` to download an image before the example command. Added `hidelines={1..2}` attribute to the code block. * *Relevance:* Improves example reproducibility by setting up a temp directory and dummy data automatically. * **Page: `build-with-claude/pdf-support.md`** * *Change:* Multiple instances of adding `cd "$(mktemp -d)"` and download commands before `curl` commands to upload/process PDFs. Also adding `hidelines` attributes. * *Relevance:* Similar to vision.md, improves example code robustness/copy-paste usability. * **Page: `build-with-claude/prompt-caching.md`** * *Change:* Major re-write of the "How automatic prefix checking works" section. * *Details:* * Clarified "Cache keys are cumulative" -> "Cache writes happen only at your breakpoint". * Clarified "Backward sequential checking" -> "Cache reads look backward...". * Clarified "20-block lookback window". * Rewrote examples to be clearer (Turn 1, 2, 3). * Added "Common mistake" section (placing breakpoint on changing content). * Updated "When to use multiple breakpoints". * Updated "Important limitation". * Updated "Best practices". * *Relevance:* **High Impact**. Deeply technical clarification of a cost-critical feature (prompt caching). Misunderstanding this costs money. * **Page: `build-with-claude/claude-on-amazon-bedrock.md`** * *Change:* Java Bedrock SDK version updated from `2.15.0` to `2.18.0`. * *Relevance:* Dependency update. * **Page: `build-with-claude/claude-on-vertex-ai.md`** * *Change:* Java Vertex SDK version updated from `2.15.0` to `2.18.0`. * *Relevance:* Dependency update. * **Page: `build-with-claude/claude-in-microsoft-foundry.md`** * *Change:* Java Foundry SDK version updated from `2.15.0` to `2.18.0`. * *Relevance:* Dependency update. * **Page: `agents-and-tools/tool-use/code-execution-tool.md`** * *Change 1:* Typo/grammar fix in intro text (removed dash before "improving"). * *Change 2:* Added `cd "$(mktemp -d)"` and `printf ...` to create dummy CSV files in examples. Added `hidelines`. * *Relevance:* Improves example usability. * **Page: `agents-and-tools/mcp-connector.md`** * *Change:* Added `nocheck` attribute to a TypeScript code block. * *Relevance:* Likely to suppress type checking warnings/linter errors in the documentation rendering, less impact on actual code logic. 3. **Synthesize Findings:** * **Theme 1: Dependency Updates.** Java SDKs (standard, Bedrock, Vertex, Foundry) jumped from 2.15.0 to 2.18.0. Go requirement bumped to 1.23. * **Theme 2: Documentation Code Quality.** Shell script examples now include setup steps (`cd "$(mktemp -d)"`, creating files) to ensure they work immediately without manual prep. This applies to Vision, PDF, and Code Execution. * **Theme 3: Deep Technical Clarification.** Prompt caching documentation received a significant overhaul to explain how the lookback window works and where to place breakpoints to save money. 4. **Draft the Analysis (in Chinese):** * *Overall Summary:* The updates primarily focus on upgrading Java SDKs to version 2.18.0 and significantly refining the Prompt Caching documentation to clarify cost-optimization logic. Additionally, shell script examples have been improved to be more robust and self-contained. * *Key Themes:* * **Dependency Updates:** Consistent bump of Java SDKs (standard, Bedrock, Vertex, Foundry) to 2.18.0. Go minimum version requirement raised to 1.23+. * **Prompt Caching Optimization:** Critical rewrites explaining the 20-block lookback window, write vs. read logic, and common pitfalls to avoid unnecessary costs. * **Example Robustness:** Shell examples (Vision, PDF, Code Execution) now include temp directory creation and dummy file generation (`mktemp -d`, `printf`, `curl`) for better usability. * *Impact Level:* **Medium** (leaning towards High for Prompt Caching users). * *Reasoning:* The prompt caching changes fix conceptual misunderstandings that directly lead to increased costs (missed cache hits). Dependency updates are routine but necessary. Example improvements are quality-of-life enhancements. * *Action Items:* * Update Java dependencies to `2.18.0` in your build files. * Ensure Go runtime is upgraded to version 1.23 or later. * **Critical:** Re-read the Prompt Caching section, specifically regarding breakpoint placement and the 20-block lookback limit, to ensure you are actually hitting the cache and saving money. * Review the new shell examples for patterns on handling file uploads in temporary directories. 5. **Refine and Format:** * Ensure tone is professional ("world-class programmer"). * Check markdown syntax. * Verify translation to Chinese is natural and technical terms are used correctly (e.g., "Prompt Caching", "SDK", "Dependency"). 6. **Final Polish (Self-Correction during drafting):** * *Correction:* Make sure to emphasize that the Prompt Caching change isn't just a wording tweak; it corrects a "common mistake" description that implies previous docs might have been misleading about how the system behaves automatically. * *Correction:* The Go version change is small but breaking for CI/CD pipelines stuck on 1.22. 7. **Final Output Generation** (Proceed to generate the markdown response).

1. **Analyze the Request**: * **Role**: World-class programmer analyzing documentation changes. * **Task**: Analyze a batch of 5 documentation changes (`cli-reference.md`, `mcp.md`, `overview.md`, `settings.md`, `CHANGELOG.md.md`). * **Output Format**: Markdown, specific sections (Overall Summary, Key Themes, Impact Level, Action Items). * **Language**: Chinese. 2. **Analyze the Input Diffs**: * **CHANGELOG.md.md**: * New version: `2.1.80`. * *Key Features*: * Added `--channels` flag (research preview) for MCP servers to push messages into sessions. * Added `rate_limits` field to statusline scripts. * Added `source: 'settings'` for plugin marketplaces. * Added `effort` frontmatter support. * *Fixes/Improvements*: * Fixed `--resume` dropping parallel tool results. * Fixed voice mode WebSocket failures. * Fixed `/effort` display. * Reduced memory usage on startup. * Fixed managed settings not being applied at startup. * **cli-reference.md**: * Shows a table of flags. * The diff ends abruptly (`| --ide | A`), but looking at the Changelog, `--channels` is the main new CLI addition. The diff provided is just the top of the table, but since it's a diff of `+56 / -54`, it likely represents a reorganization or additions/updates. *Correction*: The prompt shows a truncated diff. It starts with `Customize Claude Code's behavior...` and shows the table headers and some rows. I don't see the `--channels` flag explicitly in the *visible* diff, but the Changelog confirms it's a CLI change. *Wait*, let's look closer at the diff provided. It cuts off. However, the "Total changed pages: 5" suggests I need to synthesize based on the *full context* provided by the changelog and other files even if this specific diff is truncated or just showing formatting changes. Actually, the diff shows `+56 / -54`, implying significant updates to the CLI reference table. * **mcp.md**: * Added "React to external events" to the list of use cases. * Added a new subsection: "Push messages with channels". * Explains that MCP servers can push messages (CI results, alerts) into sessions. * Requires `claude/channel` capability and `--channels` flag. * **overview.md**: * Minor code block formatting changes (adding `theme={null}` multiple times - likely a build artifact or linting fix). * Updated the "Integrations" table. * Added a new row: "Push events from Telegram, Discord, or my own webhooks into a session" -> [Channels](/en/channels). * **settings.md**: * Added `channelsEnabled` setting (Managed settings only). * This allows Team/Enterprise admins to control channel usage. 3. **Synthesize the Changes**: * **New Feature (Research Preview)**: **Channels**. This is the biggest change. It allows external events (Telegram, Discord, Webhooks) to push messages into a Claude Code session via MCP. This is a shift from "pull" (user asking) to "push" (event triggering Claude). * **CLI Updates**: New flags and potentially updated documentation structure (`+56/-54` in cli-reference). * **Plugin System**: Plugins can now be declared inline in `settings.json` via `source: 'settings'`. * **Fixes**: Bug fix for `--resume` regarding parallel tool results (important for workflow continuity) and managed settings application (important for enterprise users). * **Performance**: Reduced memory usage. 4. **Draft the Analysis (Mental Draft in English)**: * *Summary*: Release 2.1.80 introduces "Channels" (MCP push-to-session) and plugin inline configuration, alongside bug fixes for session resumption and managed settings. * *Themes*: Event-driven AI workflows (Channels), extensibility (plugins/effort), stability (resume/settings fixes). * *Impact*: Medium/High. The Channels feature is a significant architectural shift (push vs pull). The `--resume` fix is critical for debugging complex flows. * *Actions*: Check out the Channels feature if using MCP. Update plugins to use inline settings. Update managed settings if applicable. 5. **Translate to Chinese and Refine**: * *Summary*: 版本 2.1.80 引入了**Channels**（频道）功能，允许 MCP 服务器将外部事件（如 Telegram、Webhooks）推送到会话中；同时增加了插件内联配置和多项稳定性修复。 * *Themes*: * **事件驱动工作流**: MCP Channels 允许 AI 被动接收外部消息（推送模式），不再仅是被动响应（拉取模式）。 * **可扩展性增强**: 插件现在支持直接在 `settings.json` 中定义，无需独立仓库。 * **会话状态恢复**: 修复了 `--resume` 丢弃并行工具结果的问题，确保复杂任务断点续传的完整性。 * *Impact*: Medium. Channels 是“Research Preview”（研究预览），虽具潜力但可能不稳定。修复项属于中等影响。 * *Actions*: * 尝试使用 `--channels` 标志配置 MCP 服务器以接收外部事件。 * 如果使用自定义插件，可迁移至 `source: 'settings'` 简化配置。 * 如果遇到会话恢复丢失上下文的问题，请更新至最新版本。 6. **Final Polish (Markdown)**: * *Structure*: Follow the prompt's request. * *Tone*: Professional, concise. *(Self-Correction during drafting)*: The diff in `cli-reference.md` was truncated, but the Changelog confirms `--channels` is a CLI addition. I should mention `--channels` explicitly in the context of CLI changes. 7. **Final Output Generation** (similar to the provided good response): * **Summary**: 版本 2.1.80 引入了实验性功能 **Channels**，允许通过 MCP 将外部消息（如 Webhook、聊天应用）推送至会话；同时增强了插件配置灵活性并修复了会话恢复和托管设置的关键 Bug。 * **Key Themes**: * **被动交互模式**: 通过 `--channels` 和 MCP 新增 `claude/channel` 能力，Claude Code 现能监听并响应外部事件（如 CI 结果、Telegram 消息），开启了事件驱动的自动化工作流。 * **插件生态简化**: 新增 `source: 'settings'` 插件源，允许直接在配置文件中声明插件，无需外部仓库引用。 * **会话状态完整性**: 关键修复了 `--resume` 丢弃并行工具调用结果的问题，确保长任务或复杂调试会话恢复后的上下文连贯性。 * **企业管控增强**: 新增 `channelsEnabled` 托管设置，允许管理员控制 Channels 功能的开启与关闭。 * **Impact**: **Medium**。虽然 Channels 是研究预览功能，但其代表了交互模式的重大转变（从“问”到“推”）。Bug 修复提升了稳定性和用户体验，特别是对于频繁使用 `--resume` 的开发者。 * **Action Items**: * 如果您的 MCP 服务器需要对外部事件（如 CI/CD、监控告警）做出反应，请研究并启用 `--channels` 标志。 * 评估是否可以将现有插件配置迁移至 `settings.json` 内联定义，以简化部署。 * 更新 CLI 以利用修复后的 `--resume` 功能，确保并行工具结果的正确恢复。 8. **Final Review against Constraints**: Concise? Yes. Insightful? Yes. Markdown? Yes. Chinese? Yes. Focus on developers? Yes.

1. **分析请求：** * **角色：** 程序员，开发者工具/文档方面的世界级专家。 * **任务：** 分析单一批次的文档更改（`build-with-claude/extended-thinking.md`）。 * **输入：** 包含 +22/-21 更改的差异视图。 * **输出格式：** Markdown，包含特定章节（总体摘要、关键主题、影响级别、行动项）。 * **语言：** 中文。 2. **分析差异（逐行）：** * *总体观察：* 大多数更改涉及微小的语言调整（语法、时态、措辞的简洁性），而不是技术逻辑或 API 结构的重大变化。 * *第 35 行：* "The API response will include" -> "The API response includes"。（时态：将来时 -> 一般现在时，更简洁）。 * *第 101 行：* 注释 "# The response will contain" -> "# The response contains"。（将来时 -> 一般现在时）。 * *第 129 行：* 注释 "// The response will contain" -> "// The response contains"。（将来时 -> 一般现在时）。 * *第 427 行：* "do not yet include" -> "don't yet include"。（风格：缩略）。 * *第 557-560 行：* Go 代码块。添加了错误处理（`resp, err := ...` 和 `if err != nil { panic(err) }`）。这是代码示例中的一个功能性改进，而非文档更改。 * *第 1199 行：* "You cannot toggle" -> "You can't toggle"。（风格：缩略）。 * *第 1203 行：* "should not contain" -> "shouldn't contain"。（风格：缩略）。 * *第 1490 行：* "The API response will include" -> "The API response includes"。（时态）。 * *第 1552 行：* 注释 "# No new thinking blocks will be generated" -> "# No new thinking blocks are generated"。（被动语态/时态调整）。 * *第 1592 行：* 注释 "// No new thinking blocks will be generated" -> "// No new thinking blocks are generated"。 * *第 1987 行：* "The API response will now **only** include text" -> "The API response now includes **only** text"。（措辞）。 * *第 2007-2011 行：* "The API will: ..." -> "The API: ..."（列表格式调整）。 * *第 2009-2011 行：* "Automatically filter..."、"Uses..."、"Only bills..."（动词匹配列表结构）。 * *第 2014 行：* "will continue" -> "continues"（时态）。 * *第 2019 行：* "you cannot rearrange" -> "you can't rearrange"。（缩略）。 * *第 3732 行：* "Be prepared for potentially longer response times due to the additional processing required for the reasoning process. Factor in that generating thinking blocks may increase overall response time." -> "Be prepared for longer response times due to additional processing. Generating thinking blocks increases overall response time."（简洁性）。 3. **综合分析：** * **总体摘要：** 更改主要是措辞、语法和时态一致性的编辑润色，以使语气更直接和简洁。Go 代码示例中增加了一个小的错误处理改进。 * **关键主题：** * 语言/语气统一（将来时 -> 一般现在时）。 * 简洁性（删除冗余词汇）。 * 代码质量改进（Go 错误处理）。 * **影响级别：** 低。这些是文档/说明性改进，不是 API 变更或功能中断。 * **行动项：** * 检查 Go 代码示例是否使用了正确的错误处理（最佳实践更新）。 * 无需更改集成代码（API 行为未变）。 4. **起草回复（用中文）：** * *总体摘要：* 本次更新主要是对 `extended-thinking.md` 文档的语言润色和代码示例优化，统一了时态和措辞，使文档更加简洁直接，并修正了一个 Go 代码示例中的错误处理逻辑。 * *关键主题：* * **语法与时态统一**：将多处描述从将来时（will include）改为现在时（includes），语气更确定。 * **措辞简化**：删除了冗余词汇（如 "potentially", "the additional processing required for"等），提升了可读性。 * **代码示例改进**：在 Go 语言的 HTTP 请求示例中补充了 `err` 错误处理逻辑。 * *影响级别：* **低**。这仅仅是文档风格的修正和最佳实践的微调，并未涉及 API 接口或核心功能的变更。 * *行动项：* * 参考更新后的 Go 示例，确保你的 HTTP 客户端代码中包含适当的错误处理。 * 无需修改现有的 API 集成代码，因为功能逻辑未变。 5. **最终审查：** 起草的回复准确反映了差异内容。Go 错误处理是对使用该特定片段的开发者唯一略微具有“技术性”的操作事项，但由于它是文档示例，总体影响仍然很低。 6. **生成最终输出。**（继续生成 markdown）。

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** 7 specific page diffs from what looks like Anthropic's documentation. * **Format:** Markdown, concise, insightful. * **Language:** Chinese. * **Structure:** 1. Overall Summary (1-2 sentences). 2. Key Themes (bullets). 3. Impact Level (Low/Medium/High/Breaking) with reasoning. 4. Action Items (bullets, max 5). 2. **Analyze the Diffs:** * **Page 1: `about-claude/pricing.md`** * Change: `Fast mode` -> `Fast mode (beta: research preview)`. * Meaning: Labeling specific availability status. * **Page 2: `about-claude/model-deprecations.md`** * Change: Updated definition of "Deprecated". Old: "not available for new customers... until retirement". New: "still functional but no longer recommended... provides recommended replacement...". * Meaning: Clarifying the lifecycle stage. It's a softening of the "not available for new customers" part (or perhaps correcting it), focusing more on the replacement path. * **Page 3: `api/rate-limits.md`** * Change: Added `(beta: research preview)` after Fast mode link. * Meaning: Consistency with Page 1. * **Page 4: `api/beta-headers.md`** * Change: "breaking changes without notice" -> "breaking changes with notice". * Meaning: Major commitment to developer experience. Breaking changes in beta will be announced, not silent. This is a positive stability signal. * **Page 5: `build-with-claude/overview.md`** * Change: Added a new section "Feature availability". * Content: Defined classifications: Beta, GA, Deprecated, Retired. Added footnotes about qualifiers like "beta: research preview". * Meaning: This is the central definition for the rest of the changes. Establishes a formal taxonomy for feature lifecycles. * **Page 6: `build-with-claude/structured-outputs.md`** * Change: "public beta" -> "beta". * Meaning: Terminology normalization to match the new taxonomy defined in Page 5. * **Page 7: `resources/glossary.md`** * Change: "public beta" -> "beta". * Meaning: Terminology normalization. 3. **Synthesize the "Overall Summary":** * Anthropic is formalizing their terminology regarding feature availability and lifecycle stages. They are standardizing terms like "beta," "GA," "deprecated," and clarifying stability guarantees (e.g., breaking changes in beta will come with notice). 4. **Identify "Key Themes":** * **Terminology Standardization:** System-wide replacement of "public beta" with "beta" and introduction of specific qualifiers like "(beta: research preview)". * **Lifecycle Formalization:** Clear definitions for Beta, GA, Deprecated, and Retired states. * **Improved Stability Guarantees:** Explicitly stating that breaking changes in Beta features will come *with* notice, not *without*. 5. **Determine "Impact Level":** * *Reasoning:* This is a documentation cleanup and policy clarification. It doesn't break code immediately. However, the change from "breaking changes without notice" to "with notice" is significant for trust, but it doesn't change how the code runs today. The renaming of stages helps planning. It's not a code-breaking change, but it affects expectations. * *Verdict:* Low to Medium. Let's go with **Low** (mostly doc/terminology changes) but arguably meaningful for enterprise risk assessment. I'll stick with **Low** because no API behavior was changed, only the description of the behavior/expectations. 6. **Draft "Action Items":** * Review the new "Feature availability" definitions to understand lifecycle stages. * Note the policy change: Beta features now guarantee notice before breaking changes (reduces risk). * Update internal documentation if referencing "public beta" (should now just say "beta"). * Check if using Fast Mode/Opus 4.6 to acknowledge the "beta: research preview" status. 7. **Translate and Format (Chinese):** * *Summary:* Anthropic 正式统一了其功能和模型生命周期的术语定义，明确了 Beta、GA、Deprecated 和 Retired 等阶段，并改进了对 Beta 功能发生重大变更时的通知承诺。 * *Themes:* * 术语标准化：将 "public beta" 统一为 "beta"，并引入了特定限定词（如 "beta: research preview"）。 * 生命周期清晰化：在 `overview.md` 中新增了正式的功能可用性分类表。 * 稳定性承诺提升：明确 Beta 功能的重大变更将“附带通知”，而非“无通知”。 * *Impact:* Low. These are documentation updates clarifying policy and terminology, not functional changes to the API. * *Action Items:* * 阅读新增的 "Feature availability" 定义，以便更好地规划技术选型。 * 注意：Beta 功能现在承诺在发生重大变更时会发出通知，这降低了在早期阶段采用新功能的风险。 * 将内部文档中提到的 "public beta" 更新为 "beta" 以保持一致性。 * 若使用 Fast Mode 或 Opus 4.6，需留意其处于 "beta: research preview" 阶段。 8. **Final Review:** * Does the output meet constraints? Yes (markdown, concise, Chinese, 4 sections). * Is the analysis accurate? Yes, it captures the shift from "public beta" to "beta", the new definitions, and the specific wording change regarding breaking changes. 9. **Construct Final Output.** (Proceeding to generate the markdown).

1. **Analyze the Request:** * **Role:** World-class programmer/analyst. * **Task:** Analyze documentation changes (specifically a diff from `vs-code.md`). * **Format:** Markdown, single batch analysis. * **Sections:** Overall Summary, Key Themes, Impact Level (with reasoning), Action Items. * **Language:** Chinese. * **Constraint:** Concise, insightful, developer-focused. 2. **Analyze the Diff:** * **File:** `vs-code.md`. * **Content:** Added a new section titled "The built-in IDE MCP server". * **Details:** * Explains the extension runs a local MCP (Model Context Protocol) server named `ide` when active. * Explains functionality: opening diffs, reading selections (`@` mentions), executing Jupyter cells. * **Transport/Auth:** Binds to `127.0.0.1`, random high port, auth token in `~/.claude/ide/` with strict permissions (`0600` file, `0700` dir). * **Tools:** Exposes tools to the model, but filters out internal RPC UI tools. * **Visible Tools:** * `mcp__ide__getDiagnostics`: Reads errors/warnings (Read-only). * `mcp__ide__executeCode`: Runs Python code in Jupyter (Write/Execute). * **Execution Flow:** `mcp__ide__executeCode` *always* asks for user confirmation via a native Quick Pick in VS Code. It fails if no notebook, no extension, or non-Python kernel. * **Note:** Distinguishes between `PreToolUse` hooks (allow proposing) and the Quick Pick (allow actual execution). 3. **Synthesize the Analysis (Internal Draft):** * *Overall Summary:* New section added explaining the internal "IDE MCP server" used by the VS Code extension. It details how the CLI interacts with the IDE for diffs, selections, and code execution, including security details and user confirmation flows. * *Key Themes:* * **Internal Architecture:** Introducing the concept of a local MCP server facilitating CLI-IDE communication. * **Security/Privacy:** Detailed explanation of localhost binding, auth tokens, and file permissions. * **Integration:** How Jupyter notebooks are integrated (code execution). * **Safety:** Explicit confirmation mechanism for code execution. * *Impact Level:* * Medium? It's mostly documentation, clarifying *how* things work under the hood. However, for developers configuring hooks or dealing with Jupyter, it's important info. It's not "Breaking" because the functionality already existed (implied by "When the extension is active..."), just now documented. So, "Low to Medium". Let's go with **Medium** because it reveals an internal surface area (`ide` server) that admins might need to allowlist. * *Action Items:* * If using `PreToolUse` hooks, add the `ide` server/tools to the allowlist. * Be aware of the confirmation dialog for Jupyter execution. * Check file permissions if `~/.claude` access is restricted in environments. 4. **Drafting the Response (in Chinese):** * *Summary:* 新增章节详细说明了 VS Code 扩展内置的 MCP 服务器 (`ide`) 的工作机制，解释了 CLI 如何通过该服务器实现差异查看、读取选中内容及 Jupyter 单元格执行。 * *Themes:* * 内部架构：CLI 与 IDE 交互的底层机制（本地 MCP 服务器）。 * 安全性：本地回环地址绑定、随机端口及严格的文件权限控制。 * 工具暴露：仅向模型暴露诊断和代码执行工具，内部 UI 工具被过滤。 * 交互确认：Jupyter 代码执行必须经过用户手动确认。 * *Impact:* **Medium**. Reason: 虽然主要是补充文档，但对企业用户（配置 `PreToolUse` 钩子）很重要。它揭示了隐式存在的服务端点，若不处理可能导致工作流受阻（虽然功能本身已存在，现在才公开）。 * *Action Items:* * 检查 `PreToolUse` 钩子，将 `mcp__ide__getDiagnostics` 和 `mcp__ide__executeCode` 加入白名单。 * 了解 Jupyter 执行流程：代码运行前会弹出原生 Quick Pick 请求确认。 * 确认 `~/.claude/ide/` 目录在受限环境下的可读写性。 5. **Refining the Output:** * Ensure the tone is professional and concise. * Check technical accuracy (e.g., distinguishing between "allow proposing" vs "allow executing"). *(Self-Correction during drafting)*: Make sure to mention that this is *documentation* of existing behavior, not necessarily a feature flag change, but for developers, understanding this MCP server is crucial for debugging and configuration. 6. **Final Polish (Chinese):** * Summary: 文档新增了对 VS Code 扩展内置 `ide` MCP 服务器的详细说明，涵盖了 CLI 集成、安全机制及 Jupyter 代码执行流程。 * Themes: CLI-IDE 集成架构、本地 MCP 服务器安全模型、工具可见性过滤、Jupyter 代码执行的确认机制。 * Impact: Medium. 原因：虽然没有改变功能，但揭示了内部依赖（MCP 服务器），对配置钩子的企业用户及维护安全边界的开发者具有参考价值。 * Actions: 配置白名单、理解执行确认流、检查目录权限。 7. **Final Output Generation** (matching the requested markdown format).
