Changes on 2026-04-23

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** Two documentation pages (`sub-agents.md` and `CHANGELOG.md.md`). * **Task:** Analyze the changes as a single batch. * **Output Format:** Concise, insightful analysis in markdown (Chinese). * **Structure:** 1. Overall Summary (1-2 sentences). 2. Key Themes (bullets). 3. Impact Level (reasoning). 4. Action Items (max 5 bullets). 2. **Analyze the Content:** * **Page 1: `sub-agents.md`** * *Changes:* Added a new section "Fork the current conversation" and related documentation. Added a note about fork mode affecting background tasks. * *New Feature:* "Forked subagents" (experimental, requires v2.1.117+, env var `CLAUDE_CODE_FORK_SUBAGENT`). * *Mechanism:* Inherits full conversation context (system prompt, tools, model, history) instead of starting fresh. Drops input isolation but keeps output isolation. * *Behavior Changes:* Forks replace the general-purpose subagent in fork mode. All subagents run in background in fork mode. `/fork` command changes behavior. * *UI:* New panel to observe/steer forks (keys: arrows, Enter, x, Esc). * *Comparison:* Table comparing Forks vs. Named Subagents (Context, System prompt, Model, Permissions, Prompt cache). * *Optimization:* Forks share prompt cache with parent (cheaper). * *Worktree:* Can use `isolation: "worktree"` with Agent tool. * *Limitations:* Interactive only, no nested forks. * **Page 2: `CHANGELOG.md.md`** * *Version:* 2.1.119. * *Major Features:* Settings persistence (`/config` to `~/.claude/settings.json`), `--from-pr` support for GitLab/Bitbucket/GHE, `--print` mode honors agent frontmatter. * *Agents/Subagents:* `--agent` honors `permissionMode`, parallel MCP server reconfiguration, various fixes for agents/MCP/worktrees. * *UI/UX:* Theme/editor mode persistence, slash command improvements, Vim mode fixes, scrolling fixes. * *Observability/Debugging:* OpenTelemetry updates, `PostToolUse` hooks now include duration. * *Fixes:* Extensive list of bug fixes (clipboard, terminal protocols, MCP OAuth, spinner, plugin loading, etc.). 3. **Synthesize and Correlate (Key Themes):** * *Theme 1: Subagent Evolution.* The `sub-agents.md` change is the biggest structural change. It introduces "Forks" (context inheritance) vs "Named Subagents" (fresh context). This is a significant workflow enhancement. * *Theme 2: Persistence and Configuration.* The changelog mentions config persistence (`~/.claude/settings.json`). This improves user experience by saving preferences. * *Theme 3: Broad Platform Support.* GitLab, Bitbucket, GitHub Enterprise support in `--from-pr`. * *Theme 4: Stability and Polish.* The changelog is full of bug fixes (MCP, clipboard, UI), indicating a focus on robustness. 4. **Drafting the Output (Iterative refinement for Chinese):** * *Overall Summary:* Claude Code v2.1.119 引入了实验性的“分叉子代理”功能，允许子代理继承完整的对话上下文，同时增强了配置持久化及对 GitLab/Bitbucket 的支持。 * *Key Themes:* * **Experimental Forked Subagents:** New model for context sharing. * **Configuration Persistence:** Settings now stick. * **Multi-Platform Git Support:** Not just GitHub anymore. * **Robustness & Polish:** Many bug fixes and UI improvements. * *Impact Level:* * *Level:* Medium-High. * *Reasoning:* The "Fork" feature changes how subagents work (context inheritance), which is a paradigm shift for complex workflows. Config persistence is a big QoL upgrade. * *Action Items:* * Try out `CLAUDE_CODE_FORK_SUBAGENT`. * Review new `/fork` command usage. * Check settings persistence. * Note the background behavior change for fork mode. 5. **Refining the Output (Final Polish):** * *Summary:* 本次更新引入了实验性的“分叉子代理”功能，允许子代理继承当前会话的完整上下文，显著提升了并行处理能力；同时增加了配置持久化支持及对 GitLab/Bitbucket 等多平台 Git 仓库的兼容性。 * *Themes:* * **子代理模式革新**：引入“分叉”机制，打破子代理隔离，实现上下文继承和 Prompt 缓存共享，优化了并行任务处理。 * **配置与状态管理**：实现了 `/config` 设置的持久化，修复了 MCP 服务器和插件的连接及加载逻辑。 * **多平台生态支持**：`--from-pr` 现已支持 GitLab、Bitbucket 和 GitHub Enterprise。 * **交互与稳定性增强**：大量修复了终端输入、剪贴板粘贴、Vim 模式及滚动体验的 Bug。 * *Impact Level:* **High** (Feature change) / **Medium** (General release). * *Reasoning:* "Forked subagents" 改变了 AI 辅助编程中上下文传递和并行协作的底层逻辑，对于复杂开发工作流具有重大影响。 * *Action Items:* * **尝试 Fork 模式**：设置 `CLAUDE_CODE_FORK_SUBAGENT=1` 并使用 `/fork` 命令测试上下文继承特性。 * **了解行为差异**：注意在 Fork 模式下，子代理将默认在后台运行，且权限提示方式有所不同。 * **利用新配置**：重启后检查 `~/.claude/settings.json` 是否自动保存了你的偏好设置。 * **使用 PR 导入**：在非 GitHub 仓库中尝试使用 `--from-pr` 导入合并请求。 6. **Final Review against constraints:** * Concise? Yes. * Insightful? Yes, highlights the "why" of forking (context cost vs isolation). * Chinese? Yes. * Markdown? Yes. 7. **Construct Final Output.** (Proceed to generate response based on step 5).

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** Diffs from three documentation pages (`amazon-bedrock.md`, `google-vertex-ai.md`, `microsoft-foundry.md`). * **Output Format:** Markdown, concise, insightful, focus on what matters to developers, Chinese language. * **Structure:** Overall Summary, Key Themes, Impact Level, Action Items. 2. **Analyze the Diffs:** * **Page 1: `amazon-bedrock.md`** * *Change:* Added a new environment variable `ENABLE_PROMPT_CACHING_1H=1`. * *Context:* It sits next to `DISABLE_PROMPT_CACHING=1`. * *Note Update:* The note about prompt caching now includes a warning: "Cache writes with a 1-hour TTL are billed at a higher rate than 5-minute writes." * **Page 2: `google-vertex-ai.md`** * *Change:* Added the same environment variable `ENABLE_PROMPT_CACHING_1H=1`. * *Context:* Similar to Bedrock, it's an optional override for the default TTL. * *Text Update:* The paragraph describing prompt caching was updated. It changed from "automatically supported when you specify the `cache_control` ephemeral flag" to "enabled automatically". It adds the specific instruction to use `ENABLE_PROMPT_CACHING_1H=1` for 1-hour TTL and repeats the billing warning. * **Page 3: `microsoft-foundry.md`** * *Change:* Added a new section (or paragraph) about prompt caching where there likely wasn't one before (or it was implicit), explicitly introducing `ENABLE_PROMPT_CACHING_1H=1`. * *Text Update:* Explicitly states "Prompt caching is enabled automatically" and provides the bash snippet for the 1-hour override, including the billing warning. 3. **Synthesize Key Information:** * **What changed?** Introduction of a new environment variable `ENABLE_PROMPT_CACHING_1H=1` across three major cloud provider integrations (AWS, GCP, Azure). * **Function:** Allows changing the default prompt cache Time-To-Live (TTL) from 5 minutes to 1 hour. * **Cost:** Critical detail - 1-hour TTL cache writes cost *more*. * **Default Behavior:** Clarified that prompt caching is enabled automatically (removing the need for explicit flags in some contexts or just clarifying the behavior). 4. **Draft the Analysis (Internal Draft in English -> Translate to Chinese):** * *Overall Summary:* Documentation for Bedrock, Vertex AI, and Foundry now supports a 1-hour prompt cache TTL via a new environment variable, with higher billing rates. * *Chinese:* 针对三个主要云平台提供商的文档新增了对 1 小时提示词缓存 TTL 的支持，通过环境变量 `ENABLE_PROMPT_CACHING_1H` 启用，并注明了更高的计费标准。 * *Key Themes:* * New Env Var `ENABLE_PROMPT_CACHING_1H`. * Cost implication (higher write price). * Consistency across platforms (AWS, Google, Azure). * Default is 5 minutes, opt-in for 1 hour. * *Impact Level:* Medium. It's a feature addition, not a breaking change. But cost implications are significant if used incorrectly. * *Reasoning:* Developers need to know about the cost trade-off. It changes the default caching behavior logic from "fixed 5m" to "configurable 5m vs 1h". * *Action Items:* * Evaluate if your workload benefits from 1-hour cache (e.g., long prompts used repeatedly over >5 mins). * Monitor billing if using this flag. * Update deployment configs if this feature is desired. 5. **Refine the Output (Chinese):** * **Summary:** 此次更新为 AWS Bedrock、Google Vertex AI 和 Microsoft Foundry 的集成的文档添加了通过环境变量 `ENABLE_PROMPT_CACHING_1H=1` 配置 1 小时提示词缓存 TTL 的功能，并明确指出该选项会产生更高的计费成本。 * **Themes:** * **新环境变量:** 引入 `ENABLE_PROMPT_CACHING_1H=1` 以覆盖默认的 5 分钟 TTL。 * **跨平台一致性:** 在三大云服务提供商的文档中同步了此配置说明。 * **成本透明度:** 明确警告 1 小时 TTL 的缓存写入费用高于默认的 5 分钟写入。 * **行为说明:** 阐明了提示词缓存在这些集成中默认开启。 * **Impact:** Medium (中等)。 * *Reasoning:* 这是一个非破坏性的功能增强，提供了性能优化的灵活性，但涉及计费策略的变化，若开发者不注意成本警告，可能会导致意外增加云账单。 * **Action Items:** * 评估应用场景：如果你的应用在短时间内（5 分钟内）大量复用相同的长提示词，请考虑是否需要更长的 1 小时缓存。 * 关注成本：启用该变量前，请务必评估因写入成本增加带来的预算影响。 * 更新配置脚本：如需使用 1 小时缓存，将 `ENABLE_PROMPT_CACHING_1H=1` 添加到部署环境变量中。 6. **Final Polish:** Ensure tone is professional and "world-class". Use correct terminology (TTL, Cache Writes, Billing). * *Self-Correction during drafting:* Make sure to emphasize that this is about *cache writes* being billed higher. The user might think it makes reads cheaper, but the note specifically says "writes... billed at a higher rate". 7. **Final Output Generation** (matches the provided good response).

1. **Analyze the Request:** * **Role:** World-class programmer, expert in dev tools/docs. * **Task:** Analyze documentation changes (10 pages) as a single batch. * **Output Format:** Markdown. * **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 for developers (bullets, max 5). 2. **Analyze the Content (Page by Page):** * **`api/messages.md`:** * Change 1: `effort` parameter options. Removed `"xhigh"`. Kept `"low", "medium", "high", "max"`. The summary line changed from "2 more" to explicit `or "max"`. * Change 2: `top_k` and `top_p` descriptions. Removed text saying "You usually only need to use `temperature`." and "You should either alter `temperature` or `top_p`, but not both." (for `top_p`). Now just says "Recommended for advanced use cases only." * **`api/messages/count_tokens.md`:** * Change: Same `effort` parameter update as above (removed `xhigh`). * **`api/messages/batches/create.md`:** * Change: Same `effort` parameter update and same `top_k`/`top_p` description update as `api/messages.md`. * **`api/models/list.md`:** * Change 1: Removed beta capability `"user-profiles-2026-03-24"`. Count "20 more" -> "19 more". * Change 2: Removed `xhigh` from `CapabilitySupport` structure. * **`api/beta/files/upload.md`:** * Change: Removed `"user-profiles-2026-03-24"` from beta list. * **`api/rate-limits.md`:** * Change: Rate limit for "Create endpoints" increased from 60 to 300 requests per minute. * **`build-with-claude/vision.md`:** * Change: Code examples updated. Removed `betas: ["files-api-2025-04-14"]` parameter from `anthropic.beta.files.upload` calls (TypeScript, Go, PHP). * **`build-with-claude/pdf-support.md`:** * Change: Code example updated. Removed `betas: ["files-api-2025-04-14"]` parameter from `anthropic.beta.files.upload` call (TypeScript). * **`build-with-claude/files.md`:** * Change: Multiple code examples (TS, C#, Go, PHP, Ruby) updated. * Specifics: Removed `betas: ["files-api-2025-04-14"]` from: * `upload` * `list` * `retrieveMetadata` / `GetMetadata` * `delete` / `Delete` * `download` / `Download` * **`agents-and-tools/tool-use/code-execution-tool.md`:** * Change: Code examples updated (TS, Go, PHP). Removed `betas: ["files-api-2025-04-14"]` from `upload`, `GetMetadata`, and `Download`. 3. **Synthesize Findings:** * **Theme 1: Removal of Beta Flag for Files API.** The most pervasive change is removing `betas: ["files-api-2025-04-14"]` from code samples across multiple files (vision, pdf, files, code-execution). This suggests the Files API has graduated from Beta to stable/general availability. * **Theme 2: `effort` Parameter Cleanup.** The `effort` parameter in API definitions had an `xhigh` option removed and the description clarified to explicitly list `max`. * **Theme 3: Sampling Parameter Guidance.** The documentation for `top_k` and `top_p` was simplified. The advice "You usually only need to use temperature" and the warning about mixing `temperature` and `top_p` were removed. * **Theme 4: Model Capabilities.** The `xhigh` capability support object and the specific beta string `user-profiles-2026-03-24` were removed. * **Theme 5: Rate Limit Increase.** Create endpoints rate limit bumped from 60 to 300/min. 4. **Determine Impact:** * **Breaking?** The removal of the beta flag in code samples is technically a "breaking" change *if* the API backend also strictly requires it, but usually, graduating from beta means the flag becomes optional or deprecated. However, for the *documentation*, this is a significant update. * **`xhigh` removal:** If users are using `"xhigh"`, this is a potential breaking change for them, though it seems it was replaced by `"max"`. * **Rate Limit:** This is an improvement (positive impact). * **Top_p advice:** Non-breaking, just a guidance update. * **Verdict:** Medium Impact. The removal of `xhigh` and the beta flag implies API behavior changes. Developers need to update their code. 5. **Drafting the Response (in Chinese):** * **Summary:** 文档主要更新了 Files API 的使用方式（移除 Beta 标记），清理了 `effort` 参数选项，并放宽了创建端点的速率限制。 * **Key Themes:** * Files API 正式转正 (Graduation): 移除了 `betas: ["files-api-2025-04-14"]` 参数。 * 参数变更: `effort` 参数移除了 `xhigh`，明确了 `max` 为最高级。 * 采样参数建议: `top_k` 和 `top_p` 的描述去除了“通常只需用 temperature”的建议。 * 速率提升: Create endpoints 的限速从 60 提升到 300。 * **Impact:** **Medium**. 虽然 API 看起来向后兼容（代码示例只是移除了可选标记），但 `xhigh` 的移除可能会影响现有调用。最需要注意的是 Files API 的稳定性变化。 * **Action Items:** * 更新代码：移除 Files API 调用中的 `betas` 参数。 * 检查配置：将 `effort: "xhigh"` 替换为 `"max"`。 * 利用限速：利用提升后的速率限制优化批量操作。 6. **Refining the Output (Self-Correction/Polish):** * Make sure to highlight the `xhigh` -> `max` migration clearly. * Ensure the "Breaking" aspect of the beta removal is framed as "Graduation to stable" which usually means the beta flag is no longer *needed* or *accepted* (documentation implies it's not needed anymore, effectively deprecating the flag requirement). * *Correction on `top_p`:* The text "You should either alter `temperature` or `top_p`, but not both" was removed. This is a subtle but important guidance change. It now leaves it open to the developer to experiment, or perhaps the underlying model handling changed. 7. **Final Polish (Markdown Structure):** * **Overall Summary**: 本次文档更新主要标志着 Files API 的正式发布（移除 Beta 标记），调整了模型推理 `effort` 参数的枚举值，并大幅提升了创建类端点的速率限制，同时简化了采样参数的使用建议。 * **Key Themes**: * **Files API 正式化**: 所有涉及文件上传、下载、列表和删除的代码示例均移除了 `betas: ["files-api-2025-04-14"]` 参数，表明该功能已脱离 Beta 阶段，进入稳定版。 * **参数清理与标准化**: `effort` 参数移除了 `"xhigh"` 选项，将其统一为 `"max"`；同时移除了 `CapabilitySupport` 中的 `xhigh` 字段。 * **采样参数描述简化**: `top_k` 和 `top_p` 文档删除了关于“通常只需使用 `temperature`”以及“不要同时更改 `temperature` 和 `top_p`”的硬性建议，给予了开发者更多调优自由度。 * **能力与限速调整**: 移除了过期/未发布的 Beta 功能 (`user-profiles-2026-03-24`)，并将“创建端点”的速率限制从 60 req/min 提升至 300 req/min。 * **Impact Level**: **Medium**。 * **理由**: 虽然大部分是文档同步更新，但 `xhigh` 参数的移除属于潜在的破坏性变更。Files API 的 Beta 标记移除意味着旧版代码如果强依赖该标记可能会在未来版本失效，建议尽快适配。速率限制的提升是积极的性能改进。 * **Action Items**: * 更新代码库：在调用 `anthropic.beta.files` 相关方法（upload, list, delete, download）时，移除代码中的 `betas: ["files-api-2025-04-14"]` 参数。 * 修改 effort 配置：检查现有配置，将任何使用 `"xhigh"` 的 `effort` 参数值更改为 `"max"`。 * 重新评估采样策略：参考新的文档建议，可以尝试结合使用 `temperature` 和 `top_p` 来优化模型输出，不再受限于“二选一”的建议。 * 优化批量任务：利用新的 300 req/min 速率限制，提升创建 Agent 或会话时的并发效率。 8. **Final check against constraints:** Concise? Yes. Insightful? Yes. Chinese? Yes. Markdown? Yes. Max 5 action items? Yes. *(Self-Correction during drafting Action Items)*: The instruction says "You should either alter temperature or top_p, but not both" was *removed*. Does this mean you *should* now? Or just that the advice is gone? It's safer to say "re-evaluate" rather than "you must now combine them". I will phrase it as "more freedom". 9. **Final Output Generation.**

1. **Analyze the Request:** * **Role:** World-class programmer, expert in dev tools/docs. * **Task:** Analyze a single batch of documentation changes (`data-usage.md`). * **Format:** Markdown. * **Output Content:** Overall Summary, Key Themes, Impact Level with reasoning, Action items for developers. * **Language:** Chinese (per instruction "请用中文回复"). 2. **Analyze the Diff (`data-usage.md`):** * *Image Alt Text Change:* "install/update connects to NPM" -> "install/update connects to the distribution server". (Minor, likely reflects internal architecture change or abstraction). * *Image URL Update:* New CDN hash. * *Installation Source Text:* "Claude Code is installed from NPM..." removed. "Claude Code runs locally." retained. "TLS" -> "TLS 1.2+". "not encrypted at rest" removed. * *New Table Added:* "Encryption at rest depends on your model provider". Lists Anthropic API, Amazon Bedrock, Google Cloud Vertex AI, Microsoft Foundry with specific encryption details (AES-256, KMS, CMEK, etc.). Mentions "Zero Data Retention". * *Trust Center Link Update:* Slight wording tweak ("compliance artifacts offered in" -> "compliance artifacts in"). * *Feedback Command Text:* "a Github issue is created in our public repository" -> "a GitHub issue is created in the public repository". (Minor grammar/stylistic change). Removed "and at rest" regarding encryption for feedback data (likely because it relies on the provider's storage mentioned above, or strictly only TLS is guaranteed there). 3. **Synthesize the Changes:** * **What changed?** The biggest shift is the handling of "Encryption at Rest". Previously, it explicitly said "is not encrypted at rest". Now, it delegates this to the specific model provider (Anthropic, Bedrock, Vertex, Foundry) via a detailed table. Also, installation source generalized to "distribution server". * **Why?** To support multiple model providers more accurately and reflect that Claude Code now supports different backends where encryption policies differ. It's a move towards being provider-agnostic and more precise about security guarantees. 4. **Drafting the Response (in Chinese):** * **Overall Summary:** The documentation updates clarify security specifications, specifically regarding encryption at rest and installation sources. It shifts from a blanket "no encryption at rest" statement to a provider-specific breakdown (Anthropic, Bedrock, Vertex, Foundry). * *Draft (Chinese):* 本次文档更新主要澄清了安全规格，特别是关于“静态数据加密”和安装来源的说明。文档将之前“不进行静态加密”的笼统陈述改为基于不同模型提供商（Anthropic, Bedrock, Vertex, Foundry）的详细加密策略表格。 * **Key Themes:** * Multi-provider security transparency. * Specifics on encryption (AES-256, KMS). * Removal of NPM specific installation mention in favor of "distribution server". * Update on feedback command encryption details. * *Draft (Chinese):* * **多供应商安全透明化：** 不再笼统声明无静态加密，而是详细列出了 Anthropic API、AWS Bedrock、GCP Vertex AI 和 MS Foundry 各自的加密标准（如 AES-256、KMS、CMEK）。 * **零数据保留：** 明确提到通过 Zero Data Retention 功能可防止服务端持久化存储。 * **TLS 规范升级：** 将传输层加密标准明确为 TLS 1.2+。 * **安装来源抽象化：** 安装来源描述从具体的 NPM 改为更通用的“分发服务器”，可能预示着分发渠道的多元化。 * **Impact Level:** Low to Medium. It's documentation-only, no code changes, but important for security compliance and developer understanding of data privacy. * *Draft (Chinese):* **Low（低）** * *Reasoning:* 纯文档变更，不涉及代码破坏性更改。主要澄清安全细节，帮助开发者更准确地理解数据在不同提供商下的隐私保护级别。 * **Action items for developers:** * Review the new table if using specific cloud providers (Bedrock/Vertex) to understand encryption keys. * Consider enabling Zero Data Retention if using Anthropic API for higher privacy. * Note the TLS 1.2+ requirement for corporate firewalls. * *Draft (Chinese):* * **审查安全合规性：** 如果您使用的是非 Anthropic 的提供商（如 Bedrock 或 Vertex），请查阅新增的表格以了解具体的密钥管理方式（如 KMS 或 CMEK）。 * **启用零数据保留：** 若使用 Anthropic API 并对隐私有极高要求，请考虑启用 [Zero Data Retention](/en/zero-data-retention) 以防止数据持久化。 * **检查网络策略：** 确认您的防火墙或代理支持 TLS 1.2+ 传输加密。 5. **Final Review:** * Does it meet the "concise" requirement? Yes. * Is it insightful? Yes, it identifies the shift to multi-provider support granularity. * Is it in Markdown? Yes. * Is it in Chinese? Yes. 6. **Refining the Output:** Ensure the tone is professional and "world-class programmer" style. Use clear formatting. * *Self-Correction on Action Items:* Keep it to max 5. I have 3 solid ones. Good. * *Self-Correction on Summary:* Ensure the distinction between transit and rest is clear. 7. **Final Polish (Mental Check of the Chinese output):** * "Encryption at rest" -> "静态数据加密" (standard term). * "Encryption in transit" -> "传输加密" or "传输中加密". * "Zero Data Retention" -> usually kept in English or translated as "零数据保留". Let's generate the final response based on these points.

1. **Analyze the Request:** * **Role:** World-class programmer analyzing documentation changes. * **Input:** A batch of 14 documentation pages (markdown diffs). * **Output:** Concise, insightful analysis in markdown format (Chinese). * **Structure:** 1. Overall Summary (1-2 sentences). 2. Key Themes (bullets). 3. Impact Level (Low/Medium/High/Breaking) + Reasoning. 4. Action Items for Developers (max 5 bullets). 2. **Analyze the Diffs (Page by Page):** * **cli-reference.md:** * Added `claude install [version]` command (install/reinstall native binary, accepts version, stable, latest). * Updated `--continue` description to explicitly include sessions added via `/add-dir`. * **common-workflows.md:** * Updated session picker description to include sessions started elsewhere that added the current directory with `/add-dir`. * **costs.md:** * Renamed command `/cost` to `/usage`. * Updated references to the command. * Updated `Note` about API users vs. subscribers. * **hooks.md:** * Added new hook event: `PostToolBatch` (after batch of parallel tool calls resolves). * Updated hook lifecycle diagram. * Updated hook types to include `mcp_tool`. * Updated table of matchers to include `PostToolBatch`. * Updated definition of "hook handler" to include MCP tool. * Added details on `mcp_tool` hook type. * **hooks-guide.md:** * Added `PostToolBatch` to event list. * Updated hook types count (3 others -> 4 others). * Added `"type": "mcp_tool"` to the list. * Updated event matcher table (includes `PostToolBatch`). * **interactive-mode.md:** * Added `v` and `V` keys to mode switching table (start VISUAL mode). * Added "Visual mode" section with full key mapping (d, y, c, p, r, ~, >, <, J, o, text objects, toggle). * Mentioned `Esc` exits VISUAL mode. * **model-config.md:** * Updated `availableModels` description: removed mention of "Config tool". * Updated environment variable description for third-party providers: `_NAME` and `_DESCRIPTION` now work with LLM gateways (via `ANTHROPIC_BASE_URL`). * **plugin-marketplaces.md:** * Added `<Note>` about `version` field: setting it pins updates; omitting it uses git commit SHA. * Updated `version` field description in metadata table. * Added "Version resolution and release channels" section explaining priority: `plugin.json` -> `marketplace.json` -> git SHA. * Added warning about version pinning and committing. * **plugins.md:** * Updated `version` field description in `plugin.json` section (optional, pinning behavior). * Updated step 2 of "Share your plugin" to reflect versioning strategy choice. * **plugins-reference.md:** * Added `PostToolBatch` to hook events. * Added `mcp_tool` to hook types list. * Added "Themes" section (plugins can ship color themes in `themes/`). * Updated manifest schema to include `themes` path. * Updated metadata fields table: clarified `version` behavior (pinning vs git SHA). * **settings.md:** * Updated `autoMode` description: added support for `"$defaults"` literal to inherit built-in rules. * Updated `availableModels` description: removed mention of "Config tool". * **setup.md:** * Added note about `DISABLE_AUTOUPDATER` vs `DISABLE_UPDATES` (manual updates vs blocking all). * **statusline.md:** * Updated `vim.mode` token to include `VISUAL` and `VISUAL LINE`. * **terminal-config.md:** * Updated theme section description. * Added "Create a custom theme" section (v2.1.118+). * Details on creating JSON theme files in `~/.claude/themes/`. * Updated Vim mode section to mention VISUAL mode support. 3. **Synthesize and Group Themes:** * *Theme 1: Vim Enhancements.* Added VISUAL mode (`v`, `V`) support in the prompt editor. This is a usability improvement for Vim users. * *Theme 2: Customization & Theming.* Major expansion here. Plugins can now ship themes. Users can create custom themes via JSON files. LLM gateways support display name overrides. * *Theme 3: Plugin Versioning Strategy.* Clarification and documentation around how plugin versions work (git SHA vs explicit semantic versioning). Crucial for plugin developers to understand updates. * *Theme 4: Hooks & Automation.* New `PostToolBatch` hook. New `mcp_tool` hook type. `autoMode` config now supports `"$defaults"`. * *Theme 5: CLI & Session Management.* New `claude install` command. `/cost` renamed to `/usage`. Better handling of `/add-dir` sessions in resumption. * *Theme 6: Admin/Config tweaks.* `availableModels` config cleanup. 4. **Draft the Analysis (Iterative refinement):** * *Summary:* This update introduces significant enhancements to developer experience, particularly in customization (themes), Vim editing capabilities (Visual mode), and plugin ecosystem control (versioning strategies). It also refines CLI commands and hooking mechanisms for better automation. * *Themes:* * **Advanced Customization:** Users can now create custom themes via JSON, and plugins can bundle their own color themes. * **Plugin Versioning Refined:** Explicit documentation on `plugin.json` versioning behavior (pinning vs. Git SHA) to manage updates effectively. * **Vim Editor Upgrade:** Added Visual mode support (`v`, `V`) to the prompt editor for better text manipulation. * **Automation & Hooks:** Introduced `PostToolBatch` hook and `mcp_tool` hook type; `autoMode` now supports inheriting defaults via `"$defaults"`. * **CLI & Naming Changes:** Renamed `/cost` to `/usage` and added `claude install [version]` command. * *Impact:* Medium/High. The theme customization and plugin versioning changes represent a shift in how the tool is extended. The Vim upgrade is highly requested/valued for power users. The `/cost` -> `/usage` rename is a minor breaking change in muscle memory. * *Reasoning:* New features like Visual mode and theming are substantial quality-of-life improvements. Changes to plugin versioning require developers to update their mental models (or configs) to ensure users get updates. `/cost` rename requires immediate adaptation. * *Action Items:* * **Update Muscle Memory:** Switch from using `/cost` to `/usage` for checking token usage. * **Review Plugin Versioning:** If you develop plugins, check your `version` fields. Decide if you want pinning (semantic) or auto-updates (git SHA). * **Explore Themes:** Check out `~/.claude/themes/` or update your plugins to include themes if relevant. * **Update Hooks:** Utilize the new `PostToolBatch` hook if you need to handle parallel tool call batches. * **Configure Auto-Mode:** Update `autoMode` settings to use `"$defaults"` to retain built-in rules while adding custom ones. 5. **Translate to Chinese (Professional Tone):** * *Summary:* 此次更新显著增强了开发者体验，重点包括引入了可视模式（Visual Mode）的 Vim 编辑器、全新的自定义主题机制（支持插件分发），以及明确了插件版本控制策略（语义化版本 vs Git SHA）。同时，CLI 工具新增了安装命令，并将 `/cost` 命令重命名为 `/usage`。 * *Themes:* * **主题定制化升级**: 用户可通过 JSON 创建自定义主题，且插件现在可以分发内置的主题。 * **插件版本策略明确**: 详细说明了 `version` 字段的行为（“固定版本” vs “基于 Git Commit 自动更新”），这对插件分发至关重要。 * **Vim 编辑器增强**: 在命令行输入模式中增加了 Visual Mode 支持（字符级 `v` 和行级 `V` 选择）。 * **自动化与 Hooks**: 新增 `PostToolBatch` 事件和 `mcp_tool` Hook 类型；`autoMode` 配置支持通过 `"$defaults"` 继承内置规则。 * **CLI 命令变更**: 新增 `claude install [version]` 命令；旧命令 `/cost` 被重命名为 `/usage`。 * *Impact:* **Medium (中等偏高)**。 * *Reasoning*: Vim Visual Mode 的加入极大地提升了编辑效率；主题系统和插件版本控制的改变扩展了工具的可定制性和维护方式。`/cost` 到 `/usage` 的重命名虽然简单，但属于破坏性习惯的改变。 * *Action Items:* * **适应新命令**: 将使用习惯从 `/cost` 调整为 `/usage` 以查看 Token 使用情况。 * **审查插件版本配置**: 如果开发插件，请检查 `plugin.json` 中的 `version` 字段，明确选择“固定版本”还是“Git 自动更新”策略。 * **利用新 Hook**: 尝试使用 `PostToolBatch` Hook 来批量处理并行的工具调用结果。 * **更新自动模式配置**: 在 `autoMode` 配置中加入 `"$defaults"` 字符串，以确保在添加自定义规则时保留系统默认的安全规则。 * **尝试主题定制**: 在 `~/.claude/themes/` 中创建 JSON 文件以定义个性化界面颜色。 6. **Final Review:** Check against constraints. Single batch analysis. Markdown format. Chinese language. Concise. * *Self-Correction on Impact:* Is it High? Maybe High for plugin devs and Vim users, but Medium for average users. "Medium/High" or "High" seems appropriate given the breadth of changes (Themes, Vim, Plugins, Hooks). I'll stick with High because the versioning strategy change is structural for the ecosystem, and Vim Visual mode is a major feature for the core interaction loop. Let's go with High. * *Refining Action Items:* Keep them actionable. "Update config" is better than "Check config". * *Translation Check:* "Visual Mode" -> "可视模式" or keep as "Visual Mode". Usually keeping English with context or standard translation is best. I'll use "Visual Mode (可视模式)". "PostToolBatch" keep English. 7. **Final Output Generation** (Proceeding to generate the markdown response).
