+# Model Catalog / Enabled Set Design
+
+> 本文整理 OpenRouter 大规模动态模型目录在 qwen-code 中的产品与技术设计。核心目标是避免把 300+ 模型直接灌进 `/model`，同时为后续可搜索、可筛选、可管理的模型目录体验留出清晰演进路径。
+
+## 1. 问题背景
+
+OpenRouter `GET /api/v1/models` 返回的模型数量很大，实际规模可达 300+。如果认证成功后将所有动态模型直接写入：
+
+- `settings.modelProviders.openai`
+
+则会产生一系列问题：
+
+1. `/model` 变成超长列表，键盘切换体验很差
+2. 用户首次认证后立刻面对大量模型，认知负担很高
+3. `settings.json` 被动态目录污染，长期配置语义变得模糊
+4. OpenRouter 这种“聚合目录”与用户真正“想启用哪些模型”被混为一谈
+
+因此，真正的问题不是“要不要做一个过滤弹窗”，而是：
+
+> 必须把“发现到的模型目录”和“当前启用的模型集合”这两个概念拆开。
+
+---
+
+## 2. 核心设计原则
+
+### 2.1 目录（Catalog）和启用集（Enabled Set）必须区分
+
+#### 模型目录
+
+表示系统发现到的全部可用模型，例如 OpenRouter `/models` 返回的全集。
+
+特点：
+
+- 数量可能非常大
+- 适合搜索、过滤、分组、刷新
+- 不应该直接等同于用户长期配置
+
+#### 启用集
+
+表示当前真正应该出现在 `/model` 中、并可被用户快速切换的模型子集。
+
+特点：
+
+- 应该小而精
+- 应该可预测
+- 才应该映射到长期配置
+
+### 2.2 首次认证目标是“先能用”，不是“立即做目录治理”
+
+OpenRouter OAuth 完成后的主目标是让用户尽快开始使用，而不是立刻让用户在 300+ 模型上做重决策。
+
+因此，不应该把 OpenRouter OAuth 成功流设计成：
+
+- 认证成功
+- 立即弹一个 300 项多选框
+- 要求用户手工筛选
+
+这会把认证流程变成配置管理任务，首次体验成本过高。
+
+### 2.3 `/model` 是“切换模型”入口，不是“管理模型目录”入口
+
+`/model` 的心智应保持简单：
+
+- 我当前能选哪些模型
+- 我现在想切到哪个模型
+
+而不是：
+
+- 维护海量目录
+- 搜索全平台模型
+- 批量配置 provider 集合
+
+目录管理应该由单独入口承担。
+
+---
+
+## 3. 产品结论
+
+### 3.1 Phase 1：先做正确的默认行为
+
+OpenRouter OAuth 成功后：
+
+1. 拉取完整模型目录
+2. 在内存中排序和评估
+3. 自动选出一个“推荐启用子集”
+4. 只把这个子集写入 `settings.modelProviders.openai`
+5. `/model` 只展示这个推荐子集
+
+这样可以在不引入新 schema 的前提下，先解决：
+
+- `/model` 列表过长
+- 首次体验过重
+- 配置被目录全集污染
+
+### 3.2 Phase 2：再做单独的模型目录管理入口
+
+未来单独引入一个“目录管理”入口，例如：
+
+- `/manage-models`
+
+它负责：
+
+- 搜索模型目录
+- 查看已启用 / 未启用模型
+- 多选启用或禁用模型
+- 基于目录编辑启用集
+
+### 3.3 `manage-models` 需要搜索能力
+
+对于 OpenRouter 这种 300+ 模型目录，搜索不是增强项，而是基础能力。
+
+搜索至少应覆盖：
+
+- `id`
+- `name`
+- provider 前缀（如 `qwen/`、`glm/`、`anthropic/`）
+- 派生标签（如 `free`、`vision`）
+
+但搜索属于目录管理入口的能力，不属于 Phase 1 的最小落地范围。
+
+---
+
+## 4. 为什么不先做 `/filter-model-provider`
+
+最初的直觉方案是：
+
+- 做一个 `/filter-model-provider`
+- OpenRouter OAuth 成功后立刻弹多选框
+- 由用户手工选择启用哪些 provider/models
+
+这个思路有启发，但并不是最正确的第一步，原因如下。
+
+### 4.1 命名层面不准确
+
+当前真正要管理的不是“provider”本身，而是：
+
+- OpenRouter 目录中的 model entries
+- 最终写入 `modelProviders.openai` 的启用模型子集
+
+因此 `filter-model-provider` 这个名字会让语义变得混乱。
+
+### 4.2 首次 OAuth 不该强依赖用户重决策
+
+首次使用时，用户只是希望：
+
+- 完成认证
+- 尽快开始用
+
+如果一认证完就弹 300 项多选框，反而会延迟主任务完成。
+
+### 4.3 应先把默认行为做正确，再做目录管理 UI
+
+系统首先应该能自动给出一个高质量的启用集；之后才是给高级用户更强的管理能力。
+
+---
+
+## 5. OpenRouter Phase 1 设计
+
+### 5.1 数据来源
+
+仍然基于：
+
+- `GET https://openrouter.ai/api/v1/models`
+
+### 5.2 Phase 1 的输出
+
+不是把全量目录写入配置，而是：
+
+- 从目录中选出推荐启用模型子集
+- 将该子集写入 `modelProviders.openai`
+
+### 5.3 推荐子集的目标
+
+推荐子集应满足：
+
+1. 默认就能用
+2. 数量可控
+3. 尽量覆盖常见 provider 和能力类型
+4. 优先包含 free 模型，降低第一次体验门槛
+
+### 5.4 为什么 free 要优先
+
+OpenRouter `/api/v1/models` 实际返回中包含：
+
+- `pricing.prompt`
+- `pricing.completion`
+
+并且免费模型会出现：
+
+- `pricing.prompt = "0"`
+- `pricing.completion = "0"`
+
+因此可以可靠识别 free 模型，而不是依赖名称中的 `(free)` 文案。
+
+free 优先的价值在于：
+
+- 用户即使没有充值，也能立刻试用
+- 推荐集更容易覆盖“先体验一下”的诉求
+
+但 free 不是唯一规则，不能简单等同于“按 free 排序后截前 N 个”。
+
+---
+
+## 6. 推荐子集选择原则
+
+### 6.1 不是简单取前 N 个
+
+如果只按排序后截前 N 个，很容易出现：
+
+- provider 分布单一
+- 全部挤在某一类模型
+- 无法覆盖视觉能力或长上下文能力
+
+因此推荐子集应当是“按规则挑代表”，而不是纯列表截断。
+
+### 6.2 推荐集应尽量覆盖的维度
+
+建议覆盖：
+
+- free 模型
+- 主流 provider 家族（如 Qwen / GPT / Claude / Gemini / GLM / MiniMax）
+- 至少一个视觉能力模型（如果存在）
+- 至少一个长上下文模型（如果存在）
+
+### 6.3 数量上限
+
+推荐启用集应保持可控，建议上限：
+
+- 12 ~ 20
+
+不要默认启用几十个，更不能默认启用全部。
+
+---
+
+## 7. 排序原则
+
+### 7.1 目录排序（Catalog Ordering）
+
+目录排序用于：
+
+- 未来目录管理页的默认浏览顺序
+- 推荐子集筛选的前置排序信号
+
+建议规则：
+
+1. free 模型优先
+2. 同为 free 时，再按 provider 优先级：
+   - `qwen/`
+   - `glm/`
+   - `minimax/`
+3. 其余按 `id` 稳定排序
+
+### 7.2 为什么 provider 优先级保留
+
+对于中文用户和当前产品目标，Qwen / GLM / MiniMax 的优先展示仍然有价值，因此保留 provider 优先级，但放在 free 之后。
+
+---
+
+## 8. Phase 2 设计方向：`/manage-models`
+
+### 8.1 入口职责
+
+未来引入单独入口，例如：
+
+- `/manage-models`
+
+它的职责不是“切换当前模型”，而是：
+
+- 浏览模型目录
+- 搜索模型目录
+- 查看哪些模型已启用
+- 批量启用 / 禁用模型
+
+### 8.2 为什么需要搜索
+
+当目录规模达到 300+ 时，没有搜索的管理页几乎不可用。
+
+因此 `manage-models` 应内置搜索：
+
+- 搜 `qwen`
+- 搜 `claude`
+- 搜 `free`
+- 搜 `vision`
+
+都应能快速定位。
+
+### 8.3 长期正确架构
+
+到 Phase 2，更合理的长期架构是引入独立字段保存“发现目录”，例如：
+
+- `modelCatalog`
+- `discoveredModelProviders`
+- `providerModelCatalogs`
+
+届时可以形成清晰分工：
+
+- `modelCatalog`：完整目录缓存
+- `modelProviders`：当前启用集
+
+这比把两者混在一个字段里更干净。
+
+---
+
+## 9. 当前实施决策
+
+基于以上分析，当前应优先实施：
+
+### 立即实施（Phase 1）
+
+- OpenRouter OAuth 成功后不再把全量模型落盘
+- 改为从动态目录中自动挑选推荐启用子集
+- 只将推荐子集写入 `modelProviders.openai`
+- 默认排序改为 free first，再 provider priority
+
+### 暂不实施
+
+- 暂不在 OAuth 完成后立刻弹 300 项多选框
+- 暂不把 `/model` 扩展成目录管理器
+- 暂不引入完整 catalog schema（作为下一阶段设计）
+
+---
+
+## 10. 一句话总结
+
+这次设计的关键不是“如何让用户筛掉 300 个模型”，而是：
+
+> 系统应先自动把海量目录收敛成一个高质量、可用的小集合；等用户真的需要更深控制时，再提供带搜索的模型目录管理入口。

+# OpenRouter OAuth 接入设计总结
+
+> 本文总结 qwen-code 中 OpenRouter OAuth 的接入背景、架构决策、实现细节、踩坑记录与验证方式。目标是让未来开发者在不了解上下文的前提下，也能快速理解这条链路的来龙去脉，并安全地继续演进。
+
+## 1. 背景
+
+在本轮改造之前，qwen-code 的认证体系已经支持：
+
+- Qwen OAuth
+- Alibaba Cloud Coding Plan
+- OpenAI-compatible provider（通过 `AuthType.USE_OPENAI` + `modelProviders.openai`）
+
+而 OpenRouter 在运行时其实已经有一部分能力：
+
+- core 中已存在 OpenRouter provider 适配：
+  - `packages/core/src/core/openaiContentGenerator/provider/openrouter.ts`
+- 可以识别 `openrouter.ai` base URL
+- 会自动注入 OpenRouter 所需 headers：
+  - `HTTP-Referer: https://github.com/QwenLM/qwen-code.git`
+  - `X-OpenRouter-Title: Qwen Code`
+
+所以这次设计的核心不是“从零新增一个平台”，而是：
+
+> 把 OpenRouter 作为现有 OpenAI-compatible provider 机制的一条认证路径接入 CLI 与 TUI。
+
+---
+
+## 2. 核心设计决策
+
+### 2.1 不新增 `AuthType`
+
+最终没有新增 `AuthType.OPENROUTER`，而是复用：
+
+- `AuthType.USE_OPENAI`
+- `modelProviders.openai`
+
+原因：
+
+1. **架构上更自然**：OpenRouter 对 qwen-code 来说本质上就是 OpenAI-compatible provider
+2. **减少改动面**：避免 auth status、model resolution、provider selection、settings schema 再扩一层分支
+3. **更符合现有 runtime 事实**：core 已经是按 OpenAI-compatible provider 机制消费 OpenRouter
+
+因此，OpenRouter 配置落盘后的最终状态是：
+
+- `security.auth.selectedType = openai`
+- `modelProviders.openai = [...]`
+- `env.OPENROUTER_API_KEY = <key>`
+- `model.name = <某个 OpenRouter model id>`
+
+### 2.2 不把 OpenRouter 当成“纯手填 key”功能
+
+实现上同时支持两条路径：
+
+- `qwen auth openrouter --key <...>`：手动 API key
+- `qwen auth openrouter`：浏览器 OAuth
+- `/auth -> API Key -> OpenRouter`：TUI 内浏览器 OAuth
+
+这样一来：
+
+- 自动化场景可以直接塞 key
+- 普通用户可以用浏览器走官方授权
+
+### 2.3 OpenRouter 模型列表动态拉取，但保留 fallback
+
+认证成功后会尝试拉取：
+
+- `GET https://openrouter.ai/api/v1/models`
+
+并将结果映射进 `modelProviders.openai`。
+
+如果请求失败，则 fallback 到一组默认模型，避免认证流程整体失败。
+
+---
+
+## 3. OpenRouter OAuth 目标链路
+
+目标链路如下：
+
+```text
+用户触发认证
+  ↓
+打开浏览器到 OpenRouter 授权页
+  ↓
+用户完成授权
+  ↓
+OpenRouter 重定向到本地 callback
+  http://localhost:3000/openrouter/callback?code=...
+  ↓
+CLI/TUI 本地 listener 收到 code
+  ↓
+POST /api/v1/auth/keys 交换 API key
+  ↓
+写入 settings/env/modelProviders
+  ↓
+refreshAuth(AuthType.USE_OPENAI)
+  ↓
+认证完成
+```
+
+这条链路最终由 `packages/cli/src/commands/auth/openrouterOAuth.ts` 负责。
+
+---
+
+## 4. OpenRouter OAuth API 约定
+
+在实践中确认的接口如下：
+
+- authorize URL:
+  - `https://openrouter.ai/auth`
+- exchange endpoint:
+  - `POST https://openrouter.ai/api/v1/auth/keys`
+- callback URL:
+  - `http://localhost:3000/openrouter/callback`
+- PKCE method:
+  - `S256`
+
+### 4.1 callback host 的一个关键结论
+
+最初尝试的是：
+
+- `http://127.0.0.1:3000/openrouter/callback`
+
+但实际手测发现，OpenRouter 浏览器跳回时使用的是：
+
+- `http://localhost:3000/openrouter/callback`
+
+因此后续实现与测试全部统一使用 `localhost`，否则会出现浏览器实际回调地址与本地 listener 不一致的问题。
+
+### 4.2 `Key label (optional)` 当前不可由 qwen-code 预填
+
+在 OpenRouter 授权页弹窗中，当前会看到一个：
+
+- `Key label (optional)`
+
+其默认值常见为：
+
+- `An app`
+
+这部分 UI 是 OpenRouter 托管页面的一部分，不是 qwen-code 本地渲染的表单。
+
+根据 OpenRouter 官方 TypeScript OAuth 文档，当前文档化的授权相关字段只有：
+
+- `callbackUrl`
+- `codeChallenge`
+- `codeChallengeMethod`
+- `limit`
+
+以及 code exchange 阶段的：
+
+- `code`
+- `codeChallengeMethod`
+- `codeVerifier`
+
+文档中没有出现以下这类可用于预填 key label 的字段：
+
+- `keyLabel`
+- `label`
+- `name`
+- `defaultLabel`
+
+因此截至本文撰写时，可以认为：
+
+> OpenRouter 授权页中的 `Key label (optional)` 默认值当前不是 qwen-code 可控项。
+
+即使 qwen-code 侧已经发送了品牌相关信息，例如：
+
+- `HTTP-Referer`
+- `X-OpenRouter-Title: Qwen Code`
+
+也不能据此推断 OpenRouter 会用它来填充 `Key label`。
+
+如果未来 OpenRouter 官方文档新增了相关参数，再考虑在授权 URL 构造阶段接入。
+
+---
+
+## 5. 文件结构与职责
+
+### 5.1 认证核心

+
+### 5.2 TUI `/auth` 接入
+
+| 文件                                                      | 作用                                                     |

+
+---
+
+## 6. 配置落盘约定
+
+OpenRouter OAuth 成功后，当前实现会写入：
+
+```json
+{
+  "env": {
+    "OPENROUTER_API_KEY": "..."
+  },
+  "modelProviders": {
+    "openai": [
+      {
+        "id": "...",
+        "name": "OpenRouter · ...",
+        "baseUrl": "https://openrouter.ai/api/v1",
+        "envKey": "OPENROUTER_API_KEY"
+      }
+    ]
+  },
+  "security": {
+    "auth": {
+      "selectedType": "openai"
+    }
+  },
+  "model": {
+    "name": "openai/gpt-4o-mini"
+  }
+}
+```
+
+其中：
+
+- `OPENROUTER_API_KEY` 是环境变量 key
+- OpenRouter provider 统一使用 `baseUrl = https://openrouter.ai/api/v1`
+- 认证类型保持 `openai`
+
+---
+
+## 7. 动态模型列表设计
+
+### 7.1 拉取方式
+
+认证完成后调用：
+
+- `GET https://openrouter.ai/api/v1/models`
+
+并将返回结果映射为 `ModelConfig[]`。
+
+### 7.2 映射规则
+
+当前保留的字段相对克制：
+
+- `id`
+- `name`
+- `baseUrl`
+- `envKey`
+- `capabilities.vision`（当输入 modality 包含 `image`）
+- `generationConfig.contextWindowSize`（来自 `context_length`）
+
+### 7.3 不写 `description`
+
+实践中发现，如果把 OpenRouter 原始 `description` 带进模型列表，后续 `/model` 等展示会太长，因此当前**刻意不写** `description`。
+
+### 7.4 过滤规则
+
+只保留可用于当前 CLI 主流程的模型：
+
+- 必须有 `id`
+- 如果 `output_modalities` 存在，则必须包含 `text`
+
+也就是说，纯图片输出模型会被过滤掉。
+
+### 7.5 排序规则
+
+为了更符合中文用户和国内模型偏好，动态模型列表做了稳定排序，优先：
+
+1. `qwen/`
+2. `glm/`
+3. `minimax/`
+4. 其它模型按 `id` 字母序
+
+### 7.6 fallback 模型
+
+如果动态拉取失败，则回退到当前 hardcoded defaults：
+
+- `openai/gpt-4o-mini`
+- `anthropic/claude-3.7-sonnet`
+- `google/gemini-2.5-flash`
+
+这样即使 OpenRouter models 接口异常，认证流程仍可完成。
+
+---
+
+## 8. `/auth` 对话框接入设计
+
+最开始，CLI 路径已经支持 OpenRouter，但 `/auth` 对话框并没有真正接入它。
+
+修复后，`/auth` 入口变成：
+
+```text
+/auth
+  → API Key
+    → OpenRouter
+```
+
+对应行为：
+
+1. 用户在 AuthDialog 里选择 OpenRouter
+2. `useAuth.ts` 中的 `handleOpenRouterSubmit()` 被触发
+3. 关闭 AuthDialog
+4. 切换到显式 loading 视图
+5. 完成 OAuth / key exchange / model fetch / refreshAuth
+6. 成功后退出 loading，并写入 history 提示
+
+---
+
+## 9. 认证中 UI 设计
+
+### 9.1 为什么需要单独的 loading 视图
+
+最开始 `/auth` 的问题有两个极端：
+
+1. **对话框一直不消失**：用户浏览器里已经授权成功，但 terminal 里还停在 `/auth`
+2. **过早恢复输入**：虽然对话框关了，但实际上 key 还没下发完成，用户却已经能继续输入
+
+最终确定的正确语义是：
+
+> 浏览器授权完成 ≠ CLI 已完成认证。
+
+因此在 `/auth` 路径中引入了显式 loading 视图 `ExternalAuthProgress`：
+
+- `Waiting for OpenRouter callback...`
+- `OpenRouter authorization complete. Requesting API key...`
+- `Syncing OpenRouter models and finalizing local configuration.`
+
+并在 loading 期间禁止输入，直到真正认证完成。
+
+### 9.2 状态表达
+
+`useAuth.ts` 中新增了 `externalAuthState`，用于承载 OpenRouter 这类外部 OAuth 的中间态；
+`DialogManager.tsx` 则根据：
+
+- `isAuthenticating`
+- `pendingAuthType`
+- `externalAuthState`
+
+决定渲染对应的 progress view。
+
+---
+
+## 10. 本轮排查出的关键坑
+
+这部分是本文最重要的“经验总结”。未来如果有人再接入新的浏览器 OAuth，强烈建议先看这里。
+
+### 10.1 坑一：callback host 不一致
+
+**现象**：浏览器打开正常，但 CLI 一直等不到 callback。
+
+**原因**：OpenRouter 实际跳回 `localhost`，而不是 `127.0.0.1`。
+
+**修复**：所有实现与测试统一改为：
+
+- `http://localhost:3000/openrouter/callback`
+
+---
+
+### 10.2 坑二：浏览器 callback 页面已经成功，但 CLI 仍卡很久
+
+**现象**：浏览器已经显示：
+
+```text
+OpenRouter authentication complete.
+You can return to Qwen Code.
+```
+
+但 CLI 端仍然要等几十秒。
+
+**根因**：`startOAuthCallbackListener()` 收到 `code` 后，先等待：
+
+- `server.close()`
+
+等 server 真正关闭后，才 resolve `waitForCode`。
+
+而 `server.close()` 的 callback 触发条件是：
+
+> 所有现有连接都结束
+
+浏览器的 keep-alive 连接会让这个关闭过程拖很久，于是形成“浏览器早就成功了，CLI 却还在等”的假象。
+
+**修复**：listener 收到 `code` 后：
+
+1. 先 `resolveCode(code)`
+2. 再后台异步 `close()`
+
+也就是：
+
+> 主流程先继续，server 收尾不能阻塞 OAuth。
+
+---
+
+### 10.3 坑三：即使 listener 已经先 resolve，`runOpenRouterOAuthLogin()` 还是慢
+
+**现象**：更细粒度 timing 显示：
+
+- `Waited for browser authorization`: 比如 17s
+- `Exchanged auth code for API key`: 比如 1s
+- 但 `OpenRouter OAuth callback completed`: 却仍然高达 70~90s
+
+**根因**：`runOpenRouterOAuthLogin()` 的 `finally` 中还有：
+
+```ts
+await listener.close();
+```
+
+虽然 listener 已经先把 `code` resolve 给主流程了，但函数返回前仍然被 `finally` 卡住。
+
+**修复**：
+
+```ts
+void listener.close().catch(() => undefined);
+```
+
+即 fire-and-forget，不再让 `finally` 阻塞函数返回。
+
+---
+
+### 10.4 坑四：callback timing 最初把“用户在浏览器里的操作时间”也算进去了
+
+最开始看到：
+
+- `OpenRouter OAuth callback completed in 39s`
+
+这条信息容易让人误以为“OpenRouter 下发 key 很慢”。
+
+但进一步打点后发现，这一段其实混合了：
+
+- 用户在浏览器页面里停留多久
+- OpenRouter 回调回来多久
+- `auth/keys` 换 key 多久
+
+所以后来又把 timing 拆细成：
+
+- `Waited for OpenRouter browser authorization in ...`
+- `Exchanged OpenRouter auth code for API key in ...`
+- `OpenRouter OAuth callback completed in ...`
+
+这能更精确地判断瓶颈到底在“人等待”还是“服务端慢”。
+
+---
+
+## 11. timing 打点结论
+
+实际打点后，本轮最重要的经验是：
+
+- `GET /api/v1/models` 很快，常见在 1 秒内
+- `config.refreshAuth(AuthType.USE_OPENAI)` 很快
+- `POST /api/v1/auth/keys` 也不慢，通常 1 秒左右
+- 体感中的“很慢”很多时候其实是：
+  - 用户在浏览器里停留时间
+  - callback listener/close 的错误阻塞方式
+
+换句话说：
+
+> 认证链路真正容易出问题的，往往不是业务接口本身，而是本地 callback listener 的状态机和 server 收尾顺序。
+
+这是以后再做 OAuth 接入时最值得记住的一点。
+
+---
+
+## 12. 验证方式
+
+### 12.1 定向单测
+
+主要测试文件：
+
+```bash
+cd packages/cli
+npm run test -- --run \
+  src/commands/auth/openrouterOAuth.test.ts \
+  src/commands/auth/openrouter.test.ts \
+  src/commands/auth/status.test.ts \
+  src/ui/auth/useAuth.test.ts \
+  src/ui/auth/AuthDialog.test.tsx \
+  src/ui/AppContainer.test.tsx
+```
+
+本轮最终相关定向测试通过数为：
+
+- 6 个测试文件
+- 79 个测试
+
+### 12.2 手动验证
+
+建议至少手动验证两条路径：
+
+#### CLI
+
+```bash
+npm run build && npm run bundle
+node dist/cli.js auth openrouter
+```
+
+#### TUI
+
+```bash
+npm run dev
+/auth
+```
+
+重点观察：
+
+- 浏览器是否能打开 OpenRouter 授权页
+- callback 是否落到 `http://localhost:3000/openrouter/callback`
+- terminal 中 timing 是否合理
+- 成功后是否能正确展示 auth status
+
+### 12.3 黑盒确认
+
+认证完成后，建议跑：
+
+```bash
+node dist/cli.js auth status
+```
+
+预期看到：
+
+- Authentication Method: OpenRouter
+- Current Model: `openai/gpt-4o-mini`（或将来被切到别的默认模型）
+- Status: API key configured
+
+---
+
+## 13. 未来开发者最需要知道的修改入口
+
+如果未来要继续改 OpenRouter 相关能力，优先看这几个点：
+
+### 13.1 改 OAuth 行为
+
+看：
+
+- `packages/cli/src/commands/auth/openrouterOAuth.ts`
+
+这里集中承载：
+
+- PKCE
+- callback listener
+- auth code exchange
+- dynamic model fetch
+- merge helper
+- OAuth timing
+
+### 13.2 改 CLI `qwen auth openrouter`
+
+看：
+
+- `packages/cli/src/commands/auth/handler.ts`
+
+### 13.3 改 `/auth` 交互体验
+
+看：
+
+- `packages/cli/src/ui/auth/useAuth.ts`
+- `packages/cli/src/ui/auth/AuthDialog.tsx`
+- `packages/cli/src/ui/components/DialogManager.tsx`
+- `packages/cli/src/ui/components/ExternalAuthProgress.tsx`
+
+### 13.4 改模型列表策略
+
+看：
+
+- `fetchOpenRouterModels()`
+- `toOpenRouterModelConfig()`
+- `mergeOpenRouterConfigs()`
+
+---
+
+## 14. 当前已知的后续可选优化
+
+### 14.1 默认模型选择仍是固定值
+
+目前落盘默认模型仍是：
+
+- `openai/gpt-4o-mini`
+
+即使动态模型列表已经成功拉取，也没有自动改成“动态列表里的首个可用模型”。
+
+这是刻意保持保守，但未来可以考虑进一步优化。
+
+### 14.2 模型优先级可以继续扩展
+
+当前只对以下前缀做优先：
+
+- `qwen/`
+- `glm/`
+- `minimax/`
+
+未来如有需要，可以扩展到：
+
+- `zhipu/`
+- `deepseek/`
+- `moonshotai/`
+- `stepfun/`
+- `baidu/`
+
+但要注意：
+
+- 排序规则应稳定
+- 不要和 provider 原始顺序耦合过深
+- 尽量保持简单易理解
+
+### 14.3 成功文案还可以更贴近真实阶段
+
+目前 loading 和 history 提示已经比最初清晰很多，但如果未来再做 UX 优化，建议继续坚持一个原则：
+
+> 明确区分“等待用户在浏览器授权”和“CLI 正在完成本地配置”。
+
+这比笼统地写成 `callback completed` 更能减少误解。
+
+---
+
+## 15. 总结
+
+本轮 OpenRouter OAuth 接入的经验可以浓缩成四句话：
+
+1. **OpenRouter 不需要新 auth type，复用 `AuthType.USE_OPENAI` 即可。**
+2. **浏览器 OAuth 接入最难的不是接口本身，而是本地 callback listener 的状态机。**
+3. **如果 callback 页面已经成功，但 CLI 还在卡，优先怀疑 `server.close()` / `finally` 收尾阻塞。**
+4. **想搞清楚 OAuth 慢在哪，必须拆 timing，而不是只看一个总时间。**
+
+如果未来再接入别的第三方 OAuth，建议直接复用这套思路：
+
+- 先设计清楚配置落盘语义
+- 再设计 callback listener 的生命周期
+- 最后用细粒度 timing 验证“到底慢在哪”
+
+这样能少踩很多坑。

-# Model Catalog / Enabled Set Design
-
-> 本文整理 OpenRouter 大规模动态模型目录在 qwen-code 中的产品与技术设计。核心目标是避免把 300+ 模型直接灌进 `/model`，同时为后续可搜索、可筛选、可管理的模型目录体验留出清晰演进路径。
-
-## 1. 问题背景
-
-OpenRouter `GET /api/v1/models` 返回的模型数量很大，实际规模可达 300+。如果认证成功后将所有动态模型直接写入：
-
-- `settings.modelProviders.openai`
-
-则会产生一系列问题：
-
-1. `/model` 变成超长列表，键盘切换体验很差
-2. 用户首次认证后立刻面对大量模型，认知负担很高
-3. `settings.json` 被动态目录污染，长期配置语义变得模糊
-4. OpenRouter 这种“聚合目录”与用户真正“想启用哪些模型”被混为一谈
-
-因此，真正的问题不是“要不要做一个过滤弹窗”，而是：
-
-> 必须把“发现到的模型目录”和“当前启用的模型集合”这两个概念拆开。
-
----
-
-## 2. 核心设计原则
-
-### 2.1 目录（Catalog）和启用集（Enabled Set）必须区分
-
-#### 模型目录
-
-表示系统发现到的全部可用模型，例如 OpenRouter `/models` 返回的全集。
-
-特点：
-
-- 数量可能非常大
-- 适合搜索、过滤、分组、刷新
-- 不应该直接等同于用户长期配置
-
-#### 启用集
-
-表示当前真正应该出现在 `/model` 中、并可被用户快速切换的模型子集。
-
-特点：
-
-- 应该小而精
-- 应该可预测
-- 才应该映射到长期配置
-
-### 2.2 首次认证目标是“先能用”，不是“立即做目录治理”
-
-OpenRouter OAuth 完成后的主目标是让用户尽快开始使用，而不是立刻让用户在 300+ 模型上做重决策。
-
-因此，不应该把 OpenRouter OAuth 成功流设计成：
-
-- 认证成功
-- 立即弹一个 300 项多选框
-- 要求用户手工筛选
-
-这会把认证流程变成配置管理任务，首次体验成本过高。
-
-### 2.3 `/model` 是“切换模型”入口，不是“管理模型目录”入口
-
-`/model` 的心智应保持简单：
-
-- 我当前能选哪些模型
-- 我现在想切到哪个模型
-
-而不是：
-
-- 维护海量目录
-- 搜索全平台模型
-- 批量配置 provider 集合
-
-目录管理应该由单独入口承担。
-
----
-
-## 3. 产品结论
-
-### 3.1 Phase 1：先做正确的默认行为
-
-OpenRouter OAuth 成功后：
-
-1. 拉取完整模型目录
-2. 在内存中排序和评估
-3. 自动选出一个“推荐启用子集”
-4. 只把这个子集写入 `settings.modelProviders.openai`
-5. `/model` 只展示这个推荐子集
-
-这样可以在不引入新 schema 的前提下，先解决：
-
-- `/model` 列表过长
-- 首次体验过重
-- 配置被目录全集污染
-
-### 3.2 Phase 2：再做单独的模型目录管理入口
-
-未来单独引入一个“目录管理”入口，例如：
-
-- `/manage-models`
-
-它负责：
-
-- 搜索模型目录
-- 查看已启用 / 未启用模型
-- 多选启用或禁用模型
-- 基于目录编辑启用集
-
-### 3.3 `manage-models` 需要搜索能力
-
-对于 OpenRouter 这种 300+ 模型目录，搜索不是增强项，而是基础能力。
-
-搜索至少应覆盖：
-
-- `id`
-- `name`
-- provider 前缀（如 `qwen/`、`glm/`、`anthropic/`）
-- 派生标签（如 `free`、`vision`）
-
-但搜索属于目录管理入口的能力，不属于 Phase 1 的最小落地范围。
-
----
-
-## 4. 为什么不先做 `/filter-model-provider`
-
-最初的直觉方案是：
-
-- 做一个 `/filter-model-provider`
-- OpenRouter OAuth 成功后立刻弹多选框
-- 由用户手工选择启用哪些 provider/models
-
-这个思路有启发，但并不是最正确的第一步，原因如下。
-
-### 4.1 命名层面不准确
-
-当前真正要管理的不是“provider”本身，而是：
-
-- OpenRouter 目录中的 model entries
-- 最终写入 `modelProviders.openai` 的启用模型子集
-
-因此 `filter-model-provider` 这个名字会让语义变得混乱。
-
-### 4.2 首次 OAuth 不该强依赖用户重决策
-
-首次使用时，用户只是希望：
-
-- 完成认证
-- 尽快开始用
-
-如果一认证完就弹 300 项多选框，反而会延迟主任务完成。
-
-### 4.3 应先把默认行为做正确，再做目录管理 UI
-
-系统首先应该能自动给出一个高质量的启用集；之后才是给高级用户更强的管理能力。
-
----
-
-## 5. OpenRouter Phase 1 设计
-
-### 5.1 数据来源
-
-仍然基于：
-
-- `GET https://openrouter.ai/api/v1/models`
-
-### 5.2 Phase 1 的输出
-
-不是把全量目录写入配置，而是：
-
-- 从目录中选出推荐启用模型子集
-- 将该子集写入 `modelProviders.openai`
-
-### 5.3 推荐子集的目标
-
-推荐子集应满足：
-
-1. 默认就能用
-2. 数量可控
-3. 尽量覆盖常见 provider 和能力类型
-4. 优先包含 free 模型，降低第一次体验门槛
-
-### 5.4 为什么 free 要优先
-
-OpenRouter `/api/v1/models` 实际返回中包含：
-
-- `pricing.prompt`
-- `pricing.completion`
-
-并且免费模型会出现：
-
-- `pricing.prompt = "0"`
-- `pricing.completion = "0"`
-
-因此可以可靠识别 free 模型，而不是依赖名称中的 `(free)` 文案。
-
-free 优先的价值在于：
-
-- 用户即使没有充值，也能立刻试用
-- 推荐集更容易覆盖“先体验一下”的诉求
-
-但 free 不是唯一规则，不能简单等同于“按 free 排序后截前 N 个”。
-
----
-
-## 6. 推荐子集选择原则
-
-### 6.1 不是简单取前 N 个
-
-如果只按排序后截前 N 个，很容易出现：
-
-- provider 分布单一
-- 全部挤在某一类模型
-- 无法覆盖视觉能力或长上下文能力
-
-因此推荐子集应当是“按规则挑代表”，而不是纯列表截断。
-
-### 6.2 推荐集应尽量覆盖的维度
-
-建议覆盖：
-
-- free 模型
-- 主流 provider 家族（如 Qwen / GPT / Claude / Gemini / GLM / MiniMax）
-- 至少一个视觉能力模型（如果存在）
-- 至少一个长上下文模型（如果存在）
-
-### 6.3 数量上限
-
-推荐启用集应保持可控，建议上限：
-
-- 12 ~ 20
-
-不要默认启用几十个，更不能默认启用全部。
-
----
-
-## 7. 排序原则
-
-### 7.1 目录排序（Catalog Ordering）
-
-目录排序用于：
-
-- 未来目录管理页的默认浏览顺序
-- 推荐子集筛选的前置排序信号
-
-建议规则：
-
-1. free 模型优先
-2. 同为 free 时，再按 provider 优先级：
-   - `qwen/`
-   - `glm/`
-   - `minimax/`
-3. 其余按 `id` 稳定排序
-
-### 7.2 为什么 provider 优先级保留
-
-对于中文用户和当前产品目标，Qwen / GLM / MiniMax 的优先展示仍然有价值，因此保留 provider 优先级，但放在 free 之后。
-
----
-
-## 8. Phase 2 设计方向：`/manage-models`
-
-### 8.1 入口职责
-
-未来引入单独入口，例如：
-
-- `/manage-models`
-
-它的职责不是“切换当前模型”，而是：
-
-- 浏览模型目录
-- 搜索模型目录
-- 查看哪些模型已启用
-- 批量启用 / 禁用模型
-
-### 8.2 为什么需要搜索
-
-当目录规模达到 300+ 时，没有搜索的管理页几乎不可用。
-
-因此 `manage-models` 应内置搜索：
-
-- 搜 `qwen`
-- 搜 `claude`
-- 搜 `free`
-- 搜 `vision`
-
-都应能快速定位。
-
-### 8.3 长期正确架构
-
-到 Phase 2，更合理的长期架构是引入独立字段保存“发现目录”，例如：
-
-- `modelCatalog`
-- `discoveredModelProviders`
-- `providerModelCatalogs`
-
-届时可以形成清晰分工：
-
-- `modelCatalog`：完整目录缓存
-- `modelProviders`：当前启用集
-
-这比把两者混在一个字段里更干净。
-
----
-
-## 9. 当前实施决策
-
-基于以上分析，当前应优先实施：
-
-### 立即实施（Phase 1）
-
-- OpenRouter OAuth 成功后不再把全量模型落盘
-- 改为从动态目录中自动挑选推荐启用子集
-- 只将推荐子集写入 `modelProviders.openai`
-- 默认排序改为 free first，再 provider priority
-
-### 暂不实施
-
-- 暂不在 OAuth 完成后立刻弹 300 项多选框
-- 暂不把 `/model` 扩展成目录管理器
-- 暂不引入完整 catalog schema（作为下一阶段设计）
-
----
-
-## 10. 一句话总结
-
-这次设计的关键不是“如何让用户筛掉 300 个模型”，而是：
-
-> 系统应先自动把海量目录收敛成一个高质量、可用的小集合；等用户真的需要更深控制时，再提供带搜索的模型目录管理入口。

+# OpenRouter Auth and Model Management Design
+
+This document captures the design intent behind the OpenRouter auth flow and the
+model management changes introduced with it. It intentionally focuses on the
+product and architectural choices, not implementation history.
+
+## Goals
+
+- Let users authenticate with OpenRouter from both CLI and `/auth`.
+- Reuse the existing OpenAI-compatible provider path instead of adding a new auth
+  type for OpenRouter.
+- Make the first-run experience usable without asking users to manage hundreds of
+  models immediately.
+- Keep a clear path toward richer model management via `/manage-models`.
+
+## OpenRouter Auth
+
+OpenRouter is integrated as an OpenAI-compatible provider:
+
+- auth type: `AuthType.USE_OPENAI`
+- provider settings: `modelProviders.openai`
+- API key env var: `OPENROUTER_API_KEY`
+- base URL: `https://openrouter.ai/api/v1`
+
+This avoids introducing an OpenRouter-specific `AuthType` when the runtime model
+provider path is already OpenAI-compatible. It keeps auth status, model
+resolution, provider selection, and settings schema aligned with the existing
+provider abstraction.
+
+The user-facing flows are:
+
+- `qwen auth openrouter --key <key>` for automation or direct API-key setup.
+- `qwen auth openrouter` for browser-based OAuth.
+- `/auth` → API Key → OpenRouter for the TUI flow.
+
+Browser OAuth uses OpenRouter's PKCE flow and writes the exchanged API key into
+settings before refreshing auth as `AuthType.USE_OPENAI`.
+
+## Model Management
+
+OpenRouter exposes a large dynamic model catalog. Writing every discovered model
+into `modelProviders.openai` would make `/model` noisy and would turn a long-term
+settings field into a cache of a remote catalog.
+
+The key design split is:
+
+- **Catalog**: the full set of models discovered from a source such as
+  OpenRouter.
+- **Enabled set**: the smaller set of models that should appear in `/model` and
+  be persisted in user settings.
+
+For the initial OpenRouter flow, auth should finish with a useful default enabled
+set instead of interrupting the user with a large picker. The recommended set
+should be small, stable, and biased toward models that let users try the product
+successfully, including free models when available.
+
+`/model` remains a fast model switcher. It should not become the place where
+users browse and curate a full provider catalog.
+
+## `/manage-models`
+
+Richer model management belongs in a separate `/manage-models` entry point. That
+flow should let users:
+
+- browse discovered models;
+- search by id, display name, provider prefix, and derived tags such as `free` or
+  `vision`;
+- see which models are currently enabled;
+- enable or disable models in batches.
+
+The source dimension must remain part of this design. OpenRouter is only the
+first dynamic catalog source; future sources such as ModelScope and ModelStudio
+should fit the same shape. UI complexity can be reduced, but the underlying
+source abstraction should stay available as the extension point.
+
+## Current Boundary
+
+This change should do the minimum needed to make OpenRouter auth and model setup
+pleasant:
+
+- OAuth or key-based auth configures OpenRouter through the existing
+  OpenAI-compatible provider path.
+- The initial enabled model set is curated instead of dumping the full catalog
+  into settings.
+- Full catalog storage, browsing, filtering, and batch management are deferred to
+  `/manage-models`.
+
+The design principle is simple: authentication should get users to a working
+state quickly, while model curation should live in a dedicated management flow.

-# OpenRouter OAuth 接入设计总结
-
-> 本文总结 qwen-code 中 OpenRouter OAuth 的接入背景、架构决策、实现细节、踩坑记录与验证方式。目标是让未来开发者在不了解上下文的前提下，也能快速理解这条链路的来龙去脉，并安全地继续演进。
-
-## 1. 背景
-
-在本轮改造之前，qwen-code 的认证体系已经支持：
-
-- Qwen OAuth
-- Alibaba Cloud Coding Plan
-- OpenAI-compatible provider（通过 `AuthType.USE_OPENAI` + `modelProviders.openai`）
-
-而 OpenRouter 在运行时其实已经有一部分能力：
-
-- core 中已存在 OpenRouter provider 适配：
-  - `packages/core/src/core/openaiContentGenerator/provider/openrouter.ts`
-- 可以识别 `openrouter.ai` base URL
-- 会自动注入 OpenRouter 所需 headers：
-  - `HTTP-Referer: https://github.com/QwenLM/qwen-code.git`
-  - `X-OpenRouter-Title: Qwen Code`
-
-所以这次设计的核心不是“从零新增一个平台”，而是：
-
-> 把 OpenRouter 作为现有 OpenAI-compatible provider 机制的一条认证路径接入 CLI 与 TUI。
-
----
-
-## 2. 核心设计决策
-
-### 2.1 不新增 `AuthType`
-
-最终没有新增 `AuthType.OPENROUTER`，而是复用：
-
-- `AuthType.USE_OPENAI`
-- `modelProviders.openai`
-
-原因：
-
-1. **架构上更自然**：OpenRouter 对 qwen-code 来说本质上就是 OpenAI-compatible provider
-2. **减少改动面**：避免 auth status、model resolution、provider selection、settings schema 再扩一层分支
-3. **更符合现有 runtime 事实**：core 已经是按 OpenAI-compatible provider 机制消费 OpenRouter
-
-因此，OpenRouter 配置落盘后的最终状态是：
-
-- `security.auth.selectedType = openai`
-- `modelProviders.openai = [...]`
-- `env.OPENROUTER_API_KEY = <key>`
-- `model.name = <某个 OpenRouter model id>`
-
-### 2.2 不把 OpenRouter 当成“纯手填 key”功能
-
-实现上同时支持两条路径：
-
-- `qwen auth openrouter --key <...>`：手动 API key
-- `qwen auth openrouter`：浏览器 OAuth
-- `/auth -> API Key -> OpenRouter`：TUI 内浏览器 OAuth
-
-这样一来：
-
-- 自动化场景可以直接塞 key
-- 普通用户可以用浏览器走官方授权
-
-### 2.3 OpenRouter 模型列表动态拉取，但保留 fallback
-
-认证成功后会尝试拉取：
-
-- `GET https://openrouter.ai/api/v1/models`
-
-并将结果映射进 `modelProviders.openai`。
-
-如果请求失败，则 fallback 到一组默认模型，避免认证流程整体失败。
-
----
-
-## 3. OpenRouter OAuth 目标链路
-
-目标链路如下：
-
-```text
-用户触发认证
-  ↓
-打开浏览器到 OpenRouter 授权页
-  ↓
-用户完成授权
-  ↓
-OpenRouter 重定向到本地 callback
-  http://localhost:3000/openrouter/callback?code=...
-  ↓
-CLI/TUI 本地 listener 收到 code
-  ↓
-POST /api/v1/auth/keys 交换 API key
-  ↓
-写入 settings/env/modelProviders
-  ↓
-refreshAuth(AuthType.USE_OPENAI)
-  ↓
-认证完成
-```
-
-这条链路最终由 `packages/cli/src/commands/auth/openrouterOAuth.ts` 负责。
-
----
-
-## 4. OpenRouter OAuth API 约定
-
-在实践中确认的接口如下：
-
-- authorize URL:
-  - `https://openrouter.ai/auth`
-- exchange endpoint:
-  - `POST https://openrouter.ai/api/v1/auth/keys`
-- callback URL:
-  - `http://localhost:3000/openrouter/callback`
-- PKCE method:
-  - `S256`
-
-### 4.1 callback host 的一个关键结论
-
-最初尝试的是：
-
-- `http://127.0.0.1:3000/openrouter/callback`
-
-但实际手测发现，OpenRouter 浏览器跳回时使用的是：
-
-- `http://localhost:3000/openrouter/callback`
-
-因此后续实现与测试全部统一使用 `localhost`，否则会出现浏览器实际回调地址与本地 listener 不一致的问题。
-
-### 4.2 `Key label (optional)` 当前不可由 qwen-code 预填
-
-在 OpenRouter 授权页弹窗中，当前会看到一个：
-
-- `Key label (optional)`
-
-其默认值常见为：
-
-- `An app`
-
-这部分 UI 是 OpenRouter 托管页面的一部分，不是 qwen-code 本地渲染的表单。
-
-根据 OpenRouter 官方 TypeScript OAuth 文档，当前文档化的授权相关字段只有：
-
-- `callbackUrl`
-- `codeChallenge`
-- `codeChallengeMethod`
-- `limit`
-
-以及 code exchange 阶段的：
-
-- `code`
-- `codeChallengeMethod`
-- `codeVerifier`
-
-文档中没有出现以下这类可用于预填 key label 的字段：
-
-- `keyLabel`
-- `label`
-- `name`
-- `defaultLabel`
-
-因此截至本文撰写时，可以认为：
-
-> OpenRouter 授权页中的 `Key label (optional)` 默认值当前不是 qwen-code 可控项。
-
-即使 qwen-code 侧已经发送了品牌相关信息，例如：
-
-- `HTTP-Referer`
-- `X-OpenRouter-Title: Qwen Code`
-
-也不能据此推断 OpenRouter 会用它来填充 `Key label`。
-
-如果未来 OpenRouter 官方文档新增了相关参数，再考虑在授权 URL 构造阶段接入。
-

-
----
-
-## 6. 配置落盘约定
-
-OpenRouter OAuth 成功后，当前实现会写入：
-
-```json
-{
-  "env": {
-    "OPENROUTER_API_KEY": "..."
-  },
-  "modelProviders": {
-    "openai": [
-      {
-        "id": "...",
-        "name": "OpenRouter · ...",
-        "baseUrl": "https://openrouter.ai/api/v1",
-        "envKey": "OPENROUTER_API_KEY"
-      }
-    ]
-  },
-  "security": {
-    "auth": {
-      "selectedType": "openai"
-    }
-  },
-  "model": {
-    "name": "openai/gpt-4o-mini"
-  }
-}
-```
-
-其中：
-
-- `OPENROUTER_API_KEY` 是环境变量 key
-- OpenRouter provider 统一使用 `baseUrl = https://openrouter.ai/api/v1`
-- 认证类型保持 `openai`
-
----
-
-## 7. 动态模型列表设计
-
-### 7.1 拉取方式
-
-认证完成后调用：
-
-- `GET https://openrouter.ai/api/v1/models`
-
-并将返回结果映射为 `ModelConfig[]`。
-
-### 7.2 映射规则
-
-当前保留的字段相对克制：
-
-- `id`
-- `name`
-- `baseUrl`
-- `envKey`
-- `capabilities.vision`（当输入 modality 包含 `image`）
-- `generationConfig.contextWindowSize`（来自 `context_length`）
-
-### 7.3 不写 `description`
-
-实践中发现，如果把 OpenRouter 原始 `description` 带进模型列表，后续 `/model` 等展示会太长，因此当前**刻意不写** `description`。
-
-### 7.4 过滤规则
-
-只保留可用于当前 CLI 主流程的模型：
-
-- 必须有 `id`
-- 如果 `output_modalities` 存在，则必须包含 `text`
-
-也就是说，纯图片输出模型会被过滤掉。
-
-### 7.5 排序规则
-
-为了更符合中文用户和国内模型偏好，动态模型列表做了稳定排序，优先：
-
-1. `qwen/`
-2. `glm/`
-3. `minimax/`
-4. 其它模型按 `id` 字母序
-
-### 7.6 fallback 模型
-
-如果动态拉取失败，则回退到当前 hardcoded defaults：
-
-- `openai/gpt-4o-mini`
-- `anthropic/claude-3.7-sonnet`
-- `google/gemini-2.5-flash`
-
-这样即使 OpenRouter models 接口异常，认证流程仍可完成。
-
----
-
-## 8. `/auth` 对话框接入设计
-
-最开始，CLI 路径已经支持 OpenRouter，但 `/auth` 对话框并没有真正接入它。
-
-修复后，`/auth` 入口变成：
-
-```text
-/auth
-  → API Key
-    → OpenRouter
-```
-
-对应行为：
-
-1. 用户在 AuthDialog 里选择 OpenRouter
-2. `useAuth.ts` 中的 `handleOpenRouterSubmit()` 被触发
-3. 关闭 AuthDialog
-4. 切换到显式 loading 视图
-5. 完成 OAuth / key exchange / model fetch / refreshAuth
-6. 成功后退出 loading，并写入 history 提示
-
----
-
-## 9. 认证中 UI 设计
-
-### 9.1 为什么需要单独的 loading 视图
-
-最开始 `/auth` 的问题有两个极端：
-
-1. **对话框一直不消失**：用户浏览器里已经授权成功，但 terminal 里还停在 `/auth`
-2. **过早恢复输入**：虽然对话框关了，但实际上 key 还没下发完成，用户却已经能继续输入
-
-最终确定的正确语义是：
-
-> 浏览器授权完成 ≠ CLI 已完成认证。
-
-因此在 `/auth` 路径中引入了显式 loading 视图 `ExternalAuthProgress`：
-
-- `Waiting for OpenRouter callback...`
-- `OpenRouter authorization complete. Requesting API key...`
-- `Syncing OpenRouter models and finalizing local configuration.`
-
-并在 loading 期间禁止输入，直到真正认证完成。
-
-### 9.2 状态表达
-
-`useAuth.ts` 中新增了 `externalAuthState`，用于承载 OpenRouter 这类外部 OAuth 的中间态；
-`DialogManager.tsx` 则根据：
-
-- `isAuthenticating`
-- `pendingAuthType`
-- `externalAuthState`
-
-决定渲染对应的 progress view。
-
----
-
-## 10. 本轮排查出的关键坑
-
-这部分是本文最重要的“经验总结”。未来如果有人再接入新的浏览器 OAuth，强烈建议先看这里。
-
-### 10.1 坑一：callback host 不一致
-
-**现象**：浏览器打开正常，但 CLI 一直等不到 callback。
-
-**原因**：OpenRouter 实际跳回 `localhost`，而不是 `127.0.0.1`。
-
-**修复**：所有实现与测试统一改为：
-
-- `http://localhost:3000/openrouter/callback`
-
----
-
-### 10.2 坑二：浏览器 callback 页面已经成功，但 CLI 仍卡很久
-
-**现象**：浏览器已经显示：
-
-```text
-OpenRouter authentication complete.
-You can return to Qwen Code.
-```
-
-但 CLI 端仍然要等几十秒。
-
-**根因**：`startOAuthCallbackListener()` 收到 `code` 后，先等待：
-
-- `server.close()`
-
-等 server 真正关闭后，才 resolve `waitForCode`。
-
-而 `server.close()` 的 callback 触发条件是：
-
-> 所有现有连接都结束
-
-浏览器的 keep-alive 连接会让这个关闭过程拖很久，于是形成“浏览器早就成功了，CLI 却还在等”的假象。
-
-**修复**：listener 收到 `code` 后：
-
-1. 先 `resolveCode(code)`
-2. 再后台异步 `close()`
-
-也就是：
-
-> 主流程先继续，server 收尾不能阻塞 OAuth。
-
----
-
-### 10.3 坑三：即使 listener 已经先 resolve，`runOpenRouterOAuthLogin()` 还是慢
-
-**现象**：更细粒度 timing 显示：
-
-- `Waited for browser authorization`: 比如 17s
-- `Exchanged auth code for API key`: 比如 1s
-- 但 `OpenRouter OAuth callback completed`: 却仍然高达 70~90s
-
-**根因**：`runOpenRouterOAuthLogin()` 的 `finally` 中还有：
-
-```ts
-await listener.close();
-```
-
-虽然 listener 已经先把 `code` resolve 给主流程了，但函数返回前仍然被 `finally` 卡住。
-
-**修复**：
-
-```ts
-void listener.close().catch(() => undefined);
-```
-
-即 fire-and-forget，不再让 `finally` 阻塞函数返回。
-
----
-
-### 10.4 坑四：callback timing 最初把“用户在浏览器里的操作时间”也算进去了
-
-最开始看到：
-
-- `OpenRouter OAuth callback completed in 39s`
-
-这条信息容易让人误以为“OpenRouter 下发 key 很慢”。
-
-但进一步打点后发现，这一段其实混合了：
-
-- 用户在浏览器页面里停留多久
-- OpenRouter 回调回来多久
-- `auth/keys` 换 key 多久
-
-所以后来又把 timing 拆细成：
-
-- `Waited for OpenRouter browser authorization in ...`
-- `Exchanged OpenRouter auth code for API key in ...`
-- `OpenRouter OAuth callback completed in ...`
-
-这能更精确地判断瓶颈到底在“人等待”还是“服务端慢”。
-
----
-
-## 11. timing 打点结论
-
-实际打点后，本轮最重要的经验是：
-
-- `GET /api/v1/models` 很快，常见在 1 秒内
-- `config.refreshAuth(AuthType.USE_OPENAI)` 很快
-- `POST /api/v1/auth/keys` 也不慢，通常 1 秒左右
-- 体感中的“很慢”很多时候其实是：
-  - 用户在浏览器里停留时间
-  - callback listener/close 的错误阻塞方式
-
-换句话说：
-
-> 认证链路真正容易出问题的，往往不是业务接口本身，而是本地 callback listener 的状态机和 server 收尾顺序。
-
-这是以后再做 OAuth 接入时最值得记住的一点。
-
----
-
-## 12. 验证方式
-
-### 12.1 定向单测
-
-主要测试文件：
-
-```bash
-cd packages/cli
-npm run test -- --run \
-  src/commands/auth/openrouterOAuth.test.ts \
-  src/commands/auth/openrouter.test.ts \
-  src/commands/auth/status.test.ts \
-  src/ui/auth/useAuth.test.ts \
-  src/ui/auth/AuthDialog.test.tsx \
-  src/ui/AppContainer.test.tsx
-```
-
-本轮最终相关定向测试通过数为：
-
-- 6 个测试文件
-- 79 个测试
-
-### 12.2 手动验证
-
-建议至少手动验证两条路径：
-
-#### CLI
-
-```bash
-npm run build && npm run bundle
-node dist/cli.js auth openrouter
-```
-
-#### TUI
-
-```bash
-npm run dev
-/auth
-```
-
-重点观察：
-
-- 浏览器是否能打开 OpenRouter 授权页
-- callback 是否落到 `http://localhost:3000/openrouter/callback`
-- terminal 中 timing 是否合理
-- 成功后是否能正确展示 auth status
-
-### 12.3 黑盒确认
-
-认证完成后，建议跑：
-
-```bash
-node dist/cli.js auth status
-```
-
-预期看到：
-
-- Authentication Method: OpenRouter
-- Current Model: `openai/gpt-4o-mini`（或将来被切到别的默认模型）
-- Status: API key configured
-
----
-
-## 13. 未来开发者最需要知道的修改入口
-
-如果未来要继续改 OpenRouter 相关能力，优先看这几个点：
-
-### 13.1 改 OAuth 行为
-
-看：
-
-- `packages/cli/src/commands/auth/openrouterOAuth.ts`
-
-这里集中承载：
-
-- PKCE
-- callback listener
-- auth code exchange
-- dynamic model fetch
-- merge helper
-- OAuth timing
-
-### 13.2 改 CLI `qwen auth openrouter`
-
-看：
-
-- `packages/cli/src/commands/auth/handler.ts`
-
-### 13.3 改 `/auth` 交互体验
-
-看：
-
-- `packages/cli/src/ui/auth/useAuth.ts`
-- `packages/cli/src/ui/auth/AuthDialog.tsx`
-- `packages/cli/src/ui/components/DialogManager.tsx`
-- `packages/cli/src/ui/components/ExternalAuthProgress.tsx`
-
-### 13.4 改模型列表策略
-
-看：
-
-- `fetchOpenRouterModels()`
-- `toOpenRouterModelConfig()`
-- `mergeOpenRouterConfigs()`
-
----
-
-## 14. 当前已知的后续可选优化
-
-### 14.1 默认模型选择仍是固定值
-
-目前落盘默认模型仍是：
-
-- `openai/gpt-4o-mini`
-
-即使动态模型列表已经成功拉取，也没有自动改成“动态列表里的首个可用模型”。
-
-这是刻意保持保守，但未来可以考虑进一步优化。
-
-### 14.2 模型优先级可以继续扩展
-
-当前只对以下前缀做优先：
-
-- `qwen/`
-- `glm/`
-- `minimax/`
-
-未来如有需要，可以扩展到：
-
-- `zhipu/`
-- `deepseek/`
-- `moonshotai/`
-- `stepfun/`
-- `baidu/`
-
-但要注意：
-
-- 排序规则应稳定
-- 不要和 provider 原始顺序耦合过深
-- 尽量保持简单易理解
-
-### 14.3 成功文案还可以更贴近真实阶段
-
-目前 loading 和 history 提示已经比最初清晰很多，但如果未来再做 UX 优化，建议继续坚持一个原则：
-
-> 明确区分“等待用户在浏览器授权”和“CLI 正在完成本地配置”。
-
-这比笼统地写成 `callback completed` 更能减少误解。
-
----
-
-## 15. 总结
-
-本轮 OpenRouter OAuth 接入的经验可以浓缩成四句话：
-
-1. **OpenRouter 不需要新 auth type，复用 `AuthType.USE_OPENAI` 即可。**
-2. **浏览器 OAuth 接入最难的不是接口本身，而是本地 callback listener 的状态机。**
-3. **如果 callback 页面已经成功，但 CLI 还在卡，优先怀疑 `server.close()` / `finally` 收尾阻塞。**
-4. **想搞清楚 OAuth 慢在哪，必须拆 timing，而不是只看一个总时间。**
-
-如果未来再接入别的第三方 OAuth，建议直接复用这套思路：
-
-- 先设计清楚配置落盘语义
-- 再设计 callback listener 的生命周期
-- 最后用细粒度 timing 验证“到底慢在哪”
-
-这样能少踩很多坑。

* feat(cli): Add custom API key auth wizard with 6-step setup flow

Replace the documentation-only

Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>"Custom API Key" screen with an
in-terminal wizard: Protocol select → Base URL input → API Key input →
Model ID input → JSON review → Save.

- Add 5 new ViewLevels and render functions in AuthDialog
- Implement utility functions: generateCustomApiKeyEnvKey (normalization),
  normalizeCustomModelIds (split/trim/dedupe), maskApiKey (display)
- Implement handleCustomApiKeySubmit in useAuth with backup, env key
  generation, modelProviders merge, auth refresh, and user feedback
- Wire handler through UIActionsContext and AppContainer
- Add 18 unit tests for utilities, 4 wizard flow integration tests

* feat(cli): Improve custom auth wizard with step indicators and cleaner advanced config

- Add step indicators (Step 1/6 · Protocol) to each wizard screen
- Remove redundant Protocol/Endpoint context from each step for focus
- Redesign advanced config: add descriptions to thinking/modality toggles
- Remove max tokens option; keep only thinking and modality settings
- Add ↑↓ arrow navigation with Space toggle and Enter to continue
- Generation config flows through review JSON and final submit

Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

* test: Fix Windows CI failures in fileUtils and AuthDialog tests

- fileUtils.test.ts: Mock node:child_process execFile to prevent
  pdftotext spawn that times out on Windows (ENOENT, 5s timeout)
- AuthDialog.test.tsx: Add char-by-char typeText() helper to work
  around Node 24.x + ink TextInput compatibility issue on Windows

Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com>

* fix(cli): Reset advanced wizard state and use JSON.stringify for settings preview

- Reset advancedThinkingEnabled, advancedModalityEnabled, and
  focusedConfigIndex when re-entering custom wizard to prevent
  state leakage between configurations
- Replace hand-rolled JSON string concatenation with
  JSON.stringify for settings.json preview to properly escape
  special characters in model IDs and base URLs
