### 1. Overall Summary
本次文档更新主要侧重于明确配置边界、安装流程及特定行为的实现细节。新增了对 Microsoft Foundry 环境变量配置的说明，修正了 `effortLevel` 在配置文件中的有效值限制，并阐明了命令占位符替换的单次扫描机制。
### 2. Key Themes
* **配置约束与澄清**：明确区分了会话级设置与持久化配置的界限（特别是 `max` 努力级别），并消除了对 Foundry 配置流程的模糊性。
* **环境依赖性增强**：强调 Microsoft Foundry 完全依赖环境变量进行配置，无交互式向导辅助。
* **行为定义规范化**：统一了 Skills 和 Slash Commands 中关于命令替换行为的描述，明确其为“单次通过”且不支持递归扫描。
### 3. Impact Level: **Low**
**理由**：这些变更主要是文档层面的澄清和纠错，旨在防止开发者因误解配置方式而遇到错误。虽然涉及配置限制（如 `max` 不能用于配置文件），但并未引入破坏性变更或新的 API 功能。
### 4. Action Items
* **Foundry 用户**：确保所有必要的 Azure 环境变量（如 `CLAUDE_CODE_USE_FOUNDRY`）均已正确设置，因为不存在交互式安装向导。
* **配置检查**：检查您的设置文件，确认 `effortLevel` 未设为 `max`（`max` 仅支持通过命令行 flag 会话级使用）。
* **动态命令开发**：在设计 Skills 或 Slash Commands 时，请避免尝试通过命令输出嵌套触发其他命令（即 `!cmd` 的输出不会再次被扫描）。
💭 Model Reasoning
1. **Understand the Goal**: The user wants a concise analysis of documentation changes from a developer's perspective. The changes are provided as diffs from 4 pages: `microsoft-foundry.md`, `model-config.md`, `skills.md`, and `slash-commands.md`. I need to summarize the changes, identify themes, assess impact, and suggest action items, all in Chinese.
2. **Analyze Page 1: `microsoft-foundry.md` (+4 / -0)**
* *Change*: Added a section "5. Run Claude Code" explaining how to start the tool after setting environment variables for Foundry.
* *Detail*: Explicitly states that unlike other providers (Bedrock, Vertex AI), Foundry has no interactive setup wizard and relies solely on environment variables (`CLAUDE_CODE_USE_FOUNDRY`, etc.) for configuration.
* *Developer Implication*: Clarifies the setup process for Foundry users, removing ambiguity about how the tool connects.
3. **Analyze Page 2: `model-config.md` (+1 / -1)**
* *Change*: Modified the description of the `effortLevel` setting in the settings file.
* *Detail*: Changed from just mentioning `effortLevel` to specifying valid values (`low`, `medium`, `high`, or `xhigh`). Crucially, it adds a constraint: `max` is session-only and is *not* accepted in the settings file.
* *Developer Implication*: Developers trying to set `effortLevel` to `max` permanently in settings will now know it's not allowed/expected behavior.
4. **Analyze Page 3: `skills.md` (+1 / -0)**
* *Change*: Added a note about command substitution behavior in skills.
* *Detail*: Clarifies that substitution runs once. Command output is plain text and *not* re-scanned for further `` !`<command>` `` placeholders. This prevents recursive or multi-pass command injection via placeholder expansion.
* *Developer Implication*: Fixes a potential misunderstanding about dynamic command chaining within skills/subagent frontmatter.
5. **Analyze Page 4: `slash-commands.md` (+1 / -0)**
* *Change*: Identical to Page 3.
* *Detail*: Added the same note about single-pass substitution and lack of re-scanning for placeholders.
* *Developer Implication*: Ensures consistency across documentation regarding how command placeholders are handled (applies to both skills and slash commands).
6. **Synthesize Overall Summary**:
* The changes focus on clarifying configuration limits and setup procedures. Specifically, it details Foundry's environment variable reliance, restricts the `max` effort level in settings files, and explains the single-pass nature of command substitutions.
7. **Identify Key Themes**:
* Configuration clarifications (Foundry setup, Effort levels).
* Behavior definitions (Command substitution pass mechanics).
* Error prevention (preventing invalid settings like `max` in config files).
8. **Assess Impact Level**:
* *Level*: Low.
* *Reasoning*: These are documentation clarifications and edge-case handling. No breaking changes to the actual tool functionality are described (though it clarifies that `max` effort in settings *was* invalid). It helps developers avoid misconfiguration.
9. **Determine Action Items**:
* Foundry users: ensure env vars are set correctly as there is no wizard.
* Config users: Remove `max` effort from settings files if present.
* Skill/Command authors: Don't expect recursive placeholder expansion.
10. **Draft the Output (in Chinese)**:
* *Summary*: 文档更新主要集中在明确配置约束和安装流程，特别是针对 Microsoft Foundry 的设置说明、`effortLevel` 的有效值限制以及命令替换机制的实现细节。
* *Themes*:
* 明确配置边界与环境变量依赖。
* 修正对“最大努力级别”配置的误解。
* 阐明命令占位符的“单次扫描”行为。
* *Impact*: Low. These are clarifications that prevent user error rather than changing API behavior.
* *Action Items*:
* Foundry 用户需依赖环境变量而非交互式向导。
* 检查设置文件，不要将 `effortLevel` 设为 `max`。
* 了解命令替换不支持嵌套或递归执行。
11. **Refine Formatting**: Use Markdown as requested. Ensure the tone is professional and developer-focused.
* *Self-Correction during drafting*: Make sure to explicitly mention that `max` effort is only session-only, as that's a specific constraint added. Also, note the consistency between skills and slash-commands regarding the substitution logic.
12. **Final Output Generation** (matches the provided thought structure).
