+# 台区线损 requesturl 快速修复 实现计划
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 在 `derive_request_url_from_instruction` 中添加台区线损 URL 映射，使 `sgHideBrowerserOpenPage` 命令能正确执行。
+
+**Architecture:** 在现有知乎 URL 映射模式后追加台区线损场景的硬编码映射。
+
+**Tech Stack:** Rust
+
+---
+
+### Task 1: 添加测试用例
+
+**Files:**
+- Modify: `src/service/server.rs:828` (tests 模块)
+
+- [ ] **Step 1: 在 tests 模块中添加台区线损 URL 映射测试**
+
+在 `initial_request_url_falls_back_to_zhihu_origin_for_generated_article_publish_routes` 测试后添加新测试：
+
+```rust
+    #[test]
+    fn initial_request_url_falls_back_to_lineloss_origin_for_lineloss_instructions() {
+        let request = SubmitTaskRequest {
+            instruction: "兰州公司 台区线损大数据 月累计线损率统计分析。。。".to_string(),
+            ..SubmitTaskRequest::default()
+        };
+
+        assert_eq!(
+            initial_request_url_for_submit_task(&request),
+            "http://20.76.57.61:18080"
+        );
+    }
+```
+
+- [ ] **Step 2: 运行测试验证失败**
+
+Run: `cargo test initial_request_url_falls_back_to_lineloss_origin_for_lineloss_instructions -- --nocapture`
+
+Expected: FAIL - 测试应该失败，因为还未实现映射逻辑
+
+- [ ] **Step 3: 提交测试文件**
+
+```bash
+git add src/service/server.rs
+git commit -m "test: add lineloss requesturl mapping test"
+```
+
+---
+
+### Task 2: 实现台区线损 URL 映射
+
+**Files:**
+- Modify: `src/service/server.rs:354-382` (derive_request_url_from_instruction 函数)
+
+- [ ] **Step 1: 在 derive_request_url_from_instruction 中添加台区线损映射**
+
+在第二个知乎判断块后、`None` 之前添加：
+
+```rust
+    // 台区线损相关
+    // TODO: 临时方案，后续应从 skill 配置或 deterministic_submit 解析结果中获取
+    if instruction.contains("线损") || instruction.contains("lineloss") {
+        return Some("http://20.76.57.61:18080".to_string());
+    }
+
+    None
+```
+
+完整函数应为：
+
+```rust
+fn derive_request_url_from_instruction(instruction: &str) -> Option<String> {
+    if crate::compat::workflow_executor::detect_route(instruction, None, None)
+        .is_some_and(|route| {
+            matches!(
+                route,
+                crate::compat::workflow_executor::WorkflowRoute::ZhihuHotlistExportXlsx
+                    | crate::compat::workflow_executor::WorkflowRoute::ZhihuHotlistScreen
+                    | crate::compat::workflow_executor::WorkflowRoute::ZhihuArticleEntry
+                    | crate::compat::workflow_executor::WorkflowRoute::ZhihuArticleAutoPublishGenerated
+            )
+        })
+    {
+        return Some("https://www.zhihu.com".to_string());
+    }
+
+    if crate::compat::workflow_executor::detect_route(instruction, None, None)
+        .is_some_and(|route| {
+            matches!(
+                route,
+                crate::compat::workflow_executor::WorkflowRoute::ZhihuArticleDraft
+                    | crate::compat::workflow_executor::WorkflowRoute::ZhihuArticlePublish
+            )
+        })
+    {
+        return Some("https://zhuanlan.zhihu.com".to_string());
+    }
+
+    // 台区线损相关
+    // TODO: 临时方案，后续应从 skill 配置或 deterministic_submit 解析结果中获取
+    if instruction.contains("线损") || instruction.contains("lineloss") {
+        return Some("http://20.76.57.61:18080".to_string());
+    }
+
+    None
+}
+```
+
+- [ ] **Step 2: 运行测试验证通过**
+
+Run: `cargo test initial_request_url_falls_back_to_lineloss_origin_for_lineloss_instructions -- --nocapture`
+
+Expected: PASS
+
+- [ ] **Step 3: 运行所有相关测试**
+
+Run: `cargo test initial_request_url -- --nocapture`
+
+Expected: 所有测试通过
+
+- [ ] **Step 4: 构建项目**
+
+Run: `cargo build`
+
+Expected: 编译成功，无错误
+
+- [ ] **Step 5: 提交实现**
+
+```bash
+git add src/service/server.rs
+git commit -m "feat: add lineloss URL mapping in derive_request_url_from_instruction
+
+临时方案：检测指令中包含'线损'或'lineloss'时返回台区线损平台 URL
+
+🤖 Generated with [Qoder][https://qoder.com]"
+```
+

+
+### Task 3: 端到端验证
+
+**Files:**
+- 无文件修改，仅运行验证
+
+- [ ] **Step 1: 停止现有 sgclaw 进程**
+
+确保没有 `sg_claw.exe` 在运行
+
+- [ ] **Step 2: 启动 sgclaw 服务**
+
+Run: `target\debug\sg_claw.exe --config-path ..\sgclaw_config.json service`
+
+- [ ] **Step 3: 在 service console 发送测试指令**
+
+指令: `兰州公司 台区线损大数据 月累计线损率统计分析。。。`
+
+Expected: 日志显示 `bootstrap_url=http://20.76.57.61:18080`，而非 `about:blank`
+
+- [ ] **Step 4: 验证 helper page 打开成功**
+
+Expected: 日志显示 `helper_loaded=true, ready=true`，不再超时
