+# 模型思考控制设计方案
+
+> 日期：2026-07-31
+> 状态：Phase 1 已审核并实现
+> 范围：LangBot 主仓库的模型配置、LiteLLM 请求层、Local Agent、Web 管理面板、监控与测试
+
+## 1. 结论
+
+建议为 LangBot 增加一套与厂商参数解耦的“思考策略”模型，并明确区分三个概念：
+
+1. **思考能力**：模型是否支持思考，以及支持开关、档位还是 token 预算。
+2. **思考策略**：一次请求选择厂商默认、关闭、开启或指定思考档位。
+3. **思考展示**：是否把模型返回的思考内容展示给最终用户。
+
+现有 `remove-think` 只属于第 3 类。它会过滤输出，但不会阻止模型思考，也不会降低思考 token、费用或延迟。新能力不应复用或改写这个字段。
+
+推荐实现原则：
+
+- 默认值为 `provider_default`，不向上游增加任何新参数，现有模型行为完全不变。
+- 用户显式选择的策略必须被准确执行；无法准确执行时返回明确错误，不静默降级。
+- LangBot 内部只保存统一策略，Provider 请求层负责翻译成各厂商参数。
+- `extra_args` 保留为高级逃生口，但不能成为主 UI 的思考配置方式。
+- 模型页只管理并展示能力；可写策略归属于 Local Agent 流水线，同一模型可在不同业务中使用不同思考量。
+- 原始 reasoning 数据与展示文本分开保存，保证多轮对话、工具调用和签名字段不丢失。
+
+## 2. 调研结论
+
+### 2.1 可验证资料
+
+本次结论基于以下可验证来源：
+
+- OpenAI 官方 Reasoning Guide：`reasoning.effort` 的可选值由模型决定，可包括 `none`、`minimal`、`low`、`medium`、`high`、`xhigh`、`max`；低档位偏向低延迟和低 token，高档位偏向质量。
+  - https://developers.openai.com/api/docs/guides/reasoning#reasoning-effort
+- LangBot 锁定的 LiteLLM `1.88.1` 实现。`uv.lock` 已锁定该版本，本地缓存中的适配代码可以确认 LangBot 实际依赖所支持的翻译行为。
+- LangBot 当前实现：模型级 `extra_args` 会在 `LiteLLMRequester._build_completion_args()` 中直接合并到 `acompletion()` 参数。
+
+Anthropic、Google 和 LiteLLM 的官方文档域名在本次环境中被浏览器策略禁止访问，因此下表中这些厂商的结论以 LiteLLM `1.88.1` 实际适配代码为准。实施前应再用对应厂商官方文档做一次参数范围核验，尤其是模型代际和允许值。
+
+### 2.2 厂商差异矩阵
+
+| Provider / 生态 | 可控制能力 | LiteLLM 1.88.1 统一入口 | 关键限制 | 建议支持级别 |
+| --- | --- | --- | --- | --- |
+| OpenAI | 思考档位，部分模型支持 `none` | `reasoning_effort` | 每个模型支持的档位不同，不能把 `none` 当成通用能力 | 首批完整支持 |
+| Anthropic | 旧模型使用 extended thinking + token budget；新模型可用 adaptive thinking + effort | `reasoning_effort` 或 `thinking` | `none` 表示不发送 thinking；新旧模型的映射不同 | 首批完整支持 |
+| Gemini | 2.x 主要映射为 `thinkingBudget`；3.x 主要映射为 `thinkingLevel` | `reasoning_effort` 或 `thinking` | Gemini 3 的 `none` 可能只能降到最低档，不能保证真正关闭 | 首批支持，但严格限制关闭语义 |
+| DeepSeek | 开启/关闭；当前适配不支持预算档位 | `thinking={type: enabled}`；非 `none` effort 会映射成开启 | 多轮思考模式要求回传 `reasoning_content` | 首批开关支持 |
+| xAI | 思考档位 | `reasoning_effort` | 仅 reasoning-capable 模型接受 | 首批完整支持 |
+| Ollama | `think` 布尔值；部分模型接受 low/medium/high | `reasoning_effort` | 非 gpt-oss 模型的档位可能退化为布尔开关 | 首批支持，按模型能力裁剪 UI |
+| OpenRouter | 聚合多厂商的 reasoning 参数 | `reasoning_effort`、`thinking` | 实际能力由路由后的模型决定 | 首批支持，能力未知时要求测试 |
+| Volcengine / Doubao | `thinking.type` 支持 enabled/disabled/auto | LiteLLM `volcengine` 适配器支持 `thinking` | LangBot 当前 manifest 使用 `openai`，不会进入该适配器 | 第二批，先修正路由并回归 |
+| Bailian / Qwen | 厂商兼容接口有独立思考开关/预算 | LiteLLM `dashscope` 适配器目前未提供统一 reasoning 映射 | LangBot 当前 manifest 使用 `openai`，只能通过高级参数透传 | 第二批，实施前核对官方字段 |
+| 其他 OpenAI-compatible 网关 | 取决于网关 | 尝试标准 `reasoning_effort` | 不能仅凭模型名推断完整能力 | 保守支持，默认不自动开启 |
+
+### 2.3 对 LangBot 的直接含义
+
+不能把这个功能实现成单一 `enable_thinking: bool`，原因如下：
+
+- 有的模型只有开关，有的模型只有档位，有的模型允许精确 token 预算。
+- 有的模型本身始终推理，只能降低思考量，无法真正关闭。
+- 同一个通用档位在不同厂商会映射成不同的实际预算。
+- 聚合网关和自定义 OpenAI-compatible 服务无法可靠地通过模型名识别能力。
+- “不展示思考内容”不等于“关闭思考”。
+
+## 3. 当前项目现状
+
+### 3.1 已有能力
+
+- `LLMModel.extra_args` 是 JSON 字段，Web 端已有通用高级参数编辑器。
+- `LiteLLMRequester` 会按“模型级 `extra_args`，再调用级 `extra_args`”的顺序合并参数。
+- LiteLLM 已统一处理多个 Provider 的 `reasoning_effort`、`thinking` 和返回的 `reasoning_content`。
+- `LocalAgentRunner` 的非流式、流式、工具调用和 fallback 路径都经过 `RuntimeProvider.invoke_llm*()`。
+- `remove-think` 已能控制 `<think>` 或独立 reasoning 内容是否进入展示文本。
+- Gemini 工具调用所需的 `provider_specific_fields` / thought signature 已有保留逻辑和单元测试。
+
+### 3.2 现有缺口
+
+- 管理员只能手写 `extra_args`，没有统一语义、能力提示和校验。
+- `remove-think` 名称容易被误解为关闭模型思考。
+- 模型扫描只识别 `vision` 和 `func_call`，没有 reasoning 能力。
+- 当前返回处理会把 `reasoning_content` 拼进 `<think>` 文本后删除原字段，可能损失多轮思考所需的结构化数据。
+- DeepSeek 思考模式需要在后续轮次回传 `reasoning_content`，当前链路不能保证完整保留。
+- Pipeline 只能选择模型，不能针对业务覆盖模型的思考策略。
+- 监控只记录总输入/输出 token，没有单独展示 reasoning token。
+- 部分 Provider manifest 仍声明为通用 `openai`，导致 LiteLLM 的厂商专用翻译器不会生效。

+| 测试 | `tests/unit_tests/provider/`、`web/tests/` | 翻译、服务、流式 round-trip、前端状态测试 |
+
+Phase 1 不修改 `langbot-plugin-sdk` 的公共实体或运行时协议。现有 `provider_message.Message.provider_specific_fields` 已可承载 Provider 原始 reasoning 数据；只有后续要把 reasoning 升级为跨插件公开实体时，才需要跨仓库 SDK 变更。
+
+## 4. 领域模型
+
+### 4.1 统一策略
+
+新增 `ReasoningConfig`，保存于 LLM 模型，Pipeline 可提供同结构覆盖。产品层只暴露一个离散档位：
+
+```json
+{
+  "level": "provider_default"
+}
+```
+
+字段定义：
+
+| 字段 | 类型 | 含义 |
+| --- | --- | --- |
+| `level` | `provider_default \| disabled \| enabled \| minimal \| low \| medium \| high \| xhigh \| max` | 同时表达开关和思考强度 |
+
+校验规则：
+
+- `provider_default`：不发送任何 reasoning 参数，保持厂商和模型默认行为。
+- `disabled`：明确关闭；仅当模型可真正关闭时允许保存/运行。
+- `enabled`：明确开启，但由 Provider 决定具体强度，适用于只有开关的模型。
+- `minimal` 到 `max`：明确开启，并指定强度；仅允许选择模型实际支持的档位。
+- 厂商的 `auto` 统一映射为 `provider_default`，不再增加一个重复状态。
+- 精确 token 预算不进入主数据结构。少数需要预算的场景继续通过高级参数配置，并由模型测试接口校验。
+
+### 4.2 能力描述
+
+沿用现有 `LLMModel.abilities`，新增 `reasoning` 能力标记。同时由后端在 API 返回中计算只读的 `reasoning_capabilities`：
+
+```json
+{
+  "supported": true,
+  "controls": ["toggle", "effort"],
+  "efforts": ["none", "low", "medium", "high"],
+  "can_disable": true,
+  "source": "litellm"
+}
+```
+
+设计约束：
+
+- `abilities` 仍是用户可编辑的粗粒度能力，符合现有 `vision`、`func_call` 模式。
+- `reasoning_capabilities` 不持久化，优先从 LiteLLM 模型元数据计算，避免模型升级后数据库残留过期能力。
+- 无法识别的自定义模型返回 `supported: null`、`source: unknown`，不猜测。
+- 用户可手动添加 `reasoning` ability，但未知能力模型必须先通过“测试模型”验证显式策略。
+- UI 只展示后端声明可用的控件；未知模型保留 Provider Default 和高级参数入口。
+
+### 4.3 持久化
+
+在 `llm_models` 表新增 JSON 列：
+
+```text
+reasoning_config JSON NOT NULL DEFAULT {"level":"provider_default"}
+```
+
+使用 Alembic 新迁移，不修改冻结的 legacy migration。
+
+该列作为已实现版本的兼容字段保留；新的模型页不再提供写入口，Local Agent 请求以流水线中按模型 UUID 保存的策略为准。
+
+不建议把内部策略塞进 `extra_args`，原因是当前 `extra_args` 会原样发送给 LiteLLM；使用保留键会让内部元数据泄漏到上游，并使高级参数与产品配置难以区分。
+
+## 5. 配置优先级与请求流程
+
+### 5.1 优先级
+
+```text
+Pipeline 当前候选模型策略
+        ↓ 缺少配置时固定为 provider_default
+Provider / 模型默认行为
+```
+
+请求参数合并顺序：
+
+```text
+基础参数
+  -> 模型 extra_args
+  -> 调用级 extra_args
+  -> 统一 reasoning 策略翻译结果（最后应用）
+```
+
+统一策略最后应用，可以确保流水线行为不受模型页历史设置影响。为了避免用户困惑，保存和测试时要检测 `extra_args` 中的冲突字段；当 `level != provider_default` 时，发现以下字段应直接报错：
+
+- `reasoning_effort`
+- `thinking`
+- `reasoning`
+- `extra_body` 内已知的 `thinking`、`enable_thinking`、`thinking_budget` 等字段
+
+当 `level == provider_default` 时继续允许这些高级参数，保证旧配置兼容。
+
+### 5.2 翻译层
+
+在 `pkg/provider/modelmgr/` 内新增独立的 reasoning 规范化模块，职责是：
+
+1. 读取当前流水线候选模型的请求级策略。
+2. 查询 `ProviderAPIRequester.get_reasoning_capabilities(model)`。
+3. 严格校验策略是否可以准确执行。
+4. 生成 LiteLLM 参数，不直接发 HTTP。
+5. 返回可观测的“最终生效策略”供日志和测试使用。
+
+建议接口：
+
+```python
+class ProviderAPIRequester:
+    def get_reasoning_capabilities(self, model: RuntimeLLMModel) -> ReasoningCapabilities: ...
+
+    def build_reasoning_args(
+        self,
+        model: RuntimeLLMModel,
+        config: ReasoningConfig,
+    ) -> dict[str, Any]: ...
+```
+
+LiteLLMRequester 默认优先生成统一参数：
+
+- 强度档位：`reasoning_effort=<level>`
+- 仅开启：`thinking={"type":"enabled"}` 或 Provider 等价参数
+- 关闭：优先 `reasoning_effort="none"`
+- 高级参数中的精确预算：`thinking={"type":"enabled","budget_tokens":N}`
+
+Provider 特例只放在 requester 翻译层，不进入 Pipeline 或平台适配器。
+
+### 5.3 Provider 特例
+
+- **Gemini 3**：如果 LiteLLM 能力表不能确认真正关闭，`disabled` 必须报“不支持关闭，可选择 Provider Default 或最低档”，不能把 `none` 静默映射成 low/minimal。
+- **DeepSeek**：所有非 `none` 档位最终都只是开启。能力 API 只返回 `toggle`，UI 不显示档位；多轮必须保存并回传 `reasoning_content`。
+- **Ollama**：仅对明确支持等级的模型展示 effort；其他模型只展示开关。
+- **OpenRouter**：以路由后的模型能力为准。模型未知时允许 Provider Default，显式策略必须通过测试接口。
+- **Volcengine**：使用 `thinking.type=enabled/disabled/auto`。应先让该 requester 进入 LiteLLM `volcengine` 适配器，或增加等价的明确翻译，不能依赖模型名。
+- **Bailian/Qwen**：作为第二批 Provider 专用翻译。实施前核对官方字段、模型范围、预算上下限和流式返回结构，不凭经验写接口。
+
+## 6. 返回数据与思考展示
+
+### 6.1 保留原始 reasoning
+
+当前 `LiteLLMRequester` 会读取 `reasoning_content`，将其拼接成 `<think>` 文本，再删除原字段。建议改为：
+
+```text
+上游 reasoning_content
+  ├─ 原样保存在 Message.provider_specific_fields.reasoning_content
+  └─ 根据 remove-think 决定是否渲染为 <think>...</think>
+```
+
+流式路径需要在 accumulator 中分别累计 `content` 与 `reasoning_content`，最终消息必须携带结构化 reasoning。不能只依赖已经渲染的 `<think>` 文本反向解析。
+
+这样可以同时满足：
+
+- `remove-think=true` 时用户看不到思考内容，但多轮协议仍能回传必要数据。
+- `remove-think=false` 时保持当前用户体验。
+- DeepSeek 多轮 thinking 不丢上下文。
+- Gemini thought signature、Anthropic thinking block 等 Provider 字段可以继续按结构化方式 round-trip。
+
+### 6.2 现有字段处理
+
+保留数据库和 Pipeline 配置键 `remove-think`，避免破坏兼容。Web 文案改为更准确的：
+
+- 中文：`向用户展示思考过程`
+- 英文：`Show reasoning process`
+
+UI 使用正向开关，保存时转换回 `remove-think = !showReasoning`。文案必须强调它只影响展示，不影响模型是否思考、token 或费用。
+
+## 7. Web 管理面板
+
+### 7.1 模型编辑
+
+模型页只承担能力管理和只读展示：
+
+1. `Reasoning` ability 复选框与 Vision、Function Calling 并列，供无法自动识别的自定义模型手动声明能力。
+2. 模型卡片使用简短图标或 badge 标识 reasoning 能力。
+3. 模型页不提供可写思考挡位，避免模型默认值与流水线策略形成两个控制源。
+
+### 7.2 Local Agent 流水线策略
+
+在 Local Agent 的主模型和每一个 fallback 模型下分别显示紧凑离散滑杆：
+
+1. `Provider 默认` 始终为首个选项；选择它时不向上游增加任何思考参数。
+2. 完整档位顺序为：`Provider 默认 / 关闭 / 开启 / 最低 / 低 / 中 / 高 / 极高 / 最大`。
+3. 前端只渲染后端为该模型返回的可用档位；仅开关模型显示 `Provider 默认 / 关闭 / 开启`。
+4. 模型不能真正关闭时不提供 `关闭`；能力未知时只显示不可调的 `Provider 默认`。
+5. 主模型和 fallback 分别保存策略，切换候选模型时不会把一个模型的挡位错误应用到另一个模型。
+6. Dify、Coze、Langflow、n8n 等外部 Runner 不显示该控件，因为 LangBot 不直接发起其内部模型请求。
+
+流水线配置保持旧格式兼容，并在模型选择对象中增加按 UUID 保存的映射：
+
+```json
+{
+  "model": {
+    "primary": "primary-model-uuid",
+    "fallbacks": ["fallback-model-uuid"],
+    "reasoning": {
+      "primary-model-uuid": "high"
+    }
+  }
+}
+```
+
+`provider_default` 不写入映射；缺少 `reasoning` 的旧流水线天然等价于全部使用 Provider 默认。
+
+滑杆交互要求：轨道使用现有主色和中性灰，不使用渐变；当前档位同时显示文字；支持键盘方向键和正确的 ARIA value text；窄屏下不溢出。
+
+### 7.3 i18n
+
+新增文案至少覆盖 `en_US`、`zh_Hans`；`ja_JP` 在模型面板现有同类字段已覆盖时同步补齐。不要把厂商参数名直接作为用户文案。
+
+## 8. API、MCP 与 Skill
+
+### 8.1 HTTP API
+
+模型 CRUD 增加：
+
+- 请求字段：`reasoning_config`
+- 响应字段：`reasoning_config`
+- 只读字段：`reasoning_capabilities`
+
+模型测试接口必须使用与真实请求完全相同的规范化和翻译逻辑，并在失败时返回可操作错误，例如：
+
+```text
+Model gemini-3-... cannot disable reasoning.
+Supported controls: effort=[low, medium, high].
+```
+
+可选增加只读调试信息，仅在测试接口返回：
+
+```json
+{
+  "effective_reasoning": {
+    "level": "low",
+    "translated_keys": ["reasoning_effort"]
+  }
+}
+```
+
+不得返回 API key、完整请求正文或原始思考内容。
+
+### 8.2 MCP 与技能
+
+当前 MCP 仅列出模型 Provider，没有完整模型 CRUD 工具。如果本次不新增 agent-accessible HTTP 操作，则无需强行新增 MCP 工具。
+
+如果后续让 Agent 修改模型思考策略，则必须同一提交更新：
+
+- `src/langbot/pkg/api/mcp/server.py`
+- 对应的 `skills/` 文档
+- 参数 schema 和安全说明
+
+## 9. 监控与可观测性
+
+控制思考量后，管理员需要判断质量、延迟和成本是否值得。建议第二阶段增加：
+
+- `reasoning_tokens`：从 `completion_tokens_details.reasoning_tokens` 或 Provider 等价字段提取。
+- `effective_reasoning_level`：记录规范化后的生效档位，不记录原始思考内容。
+- 模型监控页展示输入 token、可见输出 token、reasoning token、总延迟。
+- Provider 不返回细分 token 时显示未知，不推算。
+
+安全要求：日志、监控、debug API 默认都不得记录 reasoning 原文。思考内容可能包含敏感信息或系统提示，不应因为新增配置而扩大持久化范围。
+
+## 10. 兼容与迁移
+
+### 10.1 数据迁移
+
+- 所有现有 LLM 记录迁移为 `{"level":"provider_default"}`。
+- 不自动解析或迁移现有 `extra_args` 中的 reasoning 参数，避免误判嵌套结构和 Provider 语义。
+- UI 检测到旧 `extra_args` reasoning 字段时显示“由高级参数控制”，统一策略保持 Provider Default。
+- 用户主动改成统一策略时，要求先移除冲突高级参数。
+
+### 10.2 运行时兼容
+
+- `provider_default` 不产生任何新增请求参数。
+- 不改变现有 `remove-think` 的存储键和默认值。
+- 不改变已有 Provider 的 `litellm_provider`，除非该 Provider 在专项回归后单独切换。
+- `drop_params` 不能用于掩盖显式 reasoning 配置错误；显式策略被丢弃应视为失败。
+- 自托管和 toB 环境中的自定义兼容接口保持可用，未知能力不阻止 Provider Default 请求。
+
+## 11. 实施拆分
+
+### Phase 1：统一基础设施与主流 Provider
+
+- Alembic 增加 `llm_models.reasoning_config`。
+- Backend 模型实体、CRUD、测试接口支持统一配置。
+- LiteLLMRequester 增加能力查询、严格校验和参数翻译。
+- 支持 OpenAI、Anthropic、Gemini、DeepSeek、xAI、Ollama、OpenRouter 的已验证 LiteLLM 路径。
+- 修复结构化 reasoning 的非流式/流式保留。
+- 模型面板增加 reasoning ability 与只读能力标识。
+- Local Agent 主模型和每个 fallback 增加独立的请求级策略。
+
+### Phase 2：国内 Provider
+
+- 专项核对并支持 Volcengine/Doubao、Bailian/Qwen。
+- 对相关 requester 的 `litellm_provider` 变更做独立回归，避免把 reasoning 功能和通用请求行为回归混在一起。
+- 补齐扫描结果中的 reasoning capability。
+
+### Phase 3：监控与评估
+
+- 持久化 reasoning token 和生效策略。
+- 监控页增加 reasoning 成本/延迟指标。
+- 建立不同 effort 的离线质量、首 token 延迟、总耗时和 token 对比基线。
+
+## 12. 测试方案
+
+### 12.1 单元测试
+
+- `ReasoningConfig` 所有合法/非法组合。
+- `provider_default` 不产生任何新增参数。
+- 显式配置覆盖模型/调用 `extra_args` 的顺序。
+- reasoning 配置与高级参数冲突时拒绝。
+- OpenAI 档位原样映射。
+- Anthropic 档位映射，以及高级参数预算兼容。
+- Gemini 2 budget、Gemini 3 level，以及不支持真正关闭时拒绝。
+- DeepSeek 只显示/接受 toggle，非 `none` effort 不伪装成不同档位。
+- Ollama 布尔与分级模型差异。
+- Volcengine enabled/disabled/auto 翻译。
+- 未知 Provider 只允许 Provider Default，或在显式测试后使用标准参数。
+- 非流式 `reasoning_content` 保存到 `provider_specific_fields`。
+- 流式 reasoning 分片累计后仍能 round-trip。
+- Gemini thought signature 和工具调用现有测试不能回归。
+
+### 12.2 服务与持久化测试
+
+- 新建、读取、更新模型的 `reasoning_config`。
+- Alembic 从当前 head 升级后默认值正确。
+- 模型测试接口与真实 Local Agent 使用同一翻译函数。
+- 旧模型、旧 `extra_args` 和 `remove-think` 行为不变。
+
+### 12.3 前端测试
+
+- 能力不同的模型显示正确控件。
+- 离散滑杆只能停在后端返回的可用档位。
+- 当前档位文字、键盘操作和 ARIA value text 正确。
+- 仅开关模型、不可关闭模型、完整档位模型分别显示正确刻度。
+- fallback 能力不兼容时阻止保存并给出明确提示。
+- 中英文文案完整，移动端 Popover 不溢出。
+
+### 12.4 Provider 冒烟测试
+
+至少选取以下真实或可控 mock：
+
+- 一个支持 `none` 的 OpenAI reasoning 模型。
+- 一个不支持 `none` 的 reasoning 模型。
+- 一个 Anthropic adaptive thinking 模型。
+- 一个 Gemini 2.x 与一个 Gemini 3.x 模型。
+- 一个 DeepSeek hybrid thinking 模型，执行两轮含工具调用对话。
+- 一个 Ollama 本地 reasoning 模型。
+- 一个 OpenAI-compatible 自定义网关，验证 Provider Default 完全不变。
+
+每个模型比较 Provider Default、最低档、中档、高档或关闭，记录成功率、首 token 延迟、总耗时、总 token 和 reasoning token（若可用）。
+
+## 13. 风险与控制
+
+| 风险 | 影响 | 控制措施 |
+| --- | --- | --- |
+| 将“最低思考”误当成“关闭” | 用户以为节省了成本，实际仍在推理 | `can_disable` 严格校验，不静默降级 |
+| 模型能力表过期 | 新模型无法配置或旧模型报错 | 能力未知时保守；允许测试；升级 LiteLLM 时回归 |
+| 高 effort 导致延迟/费用陡增 | 用户体验和预算风险 | 默认 Provider Default；UI 提示；后续监控 reasoning token |
+| `extra_args` 与统一配置冲突 | 实际生效值不可预测 | 保存/测试时拒绝冲突；统一策略最后应用 |
+| reasoning 原文进入日志 | 敏感信息泄露 | 不记录原文，只记录策略和 token |
+| 多轮 reasoning 丢失 | 工具调用或后续轮次失败/降质 | 结构化保存并 round-trip；流式专项测试 |
+| 修改 Provider 路由造成通用回归 | 非 reasoning 请求也受影响 | 国内 Provider 路由放第二阶段，独立提交和回归 |
+
+## 14. 需要审核确认的决策
+
+1. **是否同意三层分离**：能力、策略、展示互不替代，保留 `remove-think` 仅控制展示。
+2. **是否同意严格语义**：显式关闭无法准确执行时直接报错，不自动降为最低思考。
+3. **是否同意请求级配置**：流水线按模型 UUID 保存挡位，不把产品配置塞进 `extra_args`。
+4. **是否同意 Runner 边界**：仅 Local Agent 展示控制项，外部 Runner 由其外部系统管理模型策略。
+5. **是否同意保守默认**：所有现有模型迁移为 Provider Default，不自动开启、关闭或迁移旧高级参数。
+6. **是否把结构化 reasoning 保留纳入第一阶段**：这是 DeepSeek 多轮和工具调用正确性的必要条件，建议必须纳入。
+
+## 15. 推荐审核结果
+
+建议按以上 6 项全部通过，并将 Phase 1 作为一个完整功能单元实施。不要只增加前端开关或只在 `extra_args` 中写 `reasoning_effort`；那样虽然改动小，但会继续混淆展示与推理、无法处理 Provider 差异，也无法保证多轮对话正确性。
