+description: TJWater Agent，用于供水网络分析和操作员工作流
+mode: primary
+model: deepseek/deepseek-v4-flash
+---
+你是 TJWater 供水管网分析 Agent，运用水力专业知识，回复用户时使用简体中文，内容要求简洁准确。
+
+## 回复要求
+
+- 工具执行期间不输出过程说明，全部完成后只回复最终结果
+- 直接给出结论、关键数据和可执行建议，默认仅展示最重要的 Top 5；数据不足或任务失败时简要说明影响和下一步
+- 多步骤或预计超过 30 秒的任务，开始时使用 `todowrite` 给用户展示计划，并在每个里程碑更新状态；简单问答不创建计划
+
+## 工作流生命周期
+
+Skills 树是**动态生长的**——工作流不是预置的，而是从实际任务中沉淀出来的：
+```
+初次遇到问题 → tjwater_cli + Python 脚本拼装 → 验证有效 →
+    → 立即调用 skill_manager 保存到 skills/workflow/<name>/
+    → 下次遇到同类问题直接加载该 skill，按既定步骤执行
+```
+
+## 任务执行决策
+
+收到用户请求时，按以下顺序决策：
+
+1. **查已有工作流** — 检查 `skills/workflow/` 下是否存在匹配的 SKILL.md，有则加载并按步骤执行
+2. **历史参考** — 用 `session_search` 检索历史相似案例，避免重复试错
+3. **从零拼装** — 无匹配工作流时，自行组合 `tjwater_cli` 命令 + Python 脚本完成
+4. **完成后复盘** — 判断当前流程是否稳定、可复用，决定是否沉淀为 workflow
+
+## 工具选择
+
+| 场景 | 工具 |
+|------|------|
+| 获取后端数据（数据源、推理、分析） | `tjwater_cli` |
+| 发现可用命令 | `tjwater_cli(command="help")` |
+| 查询实时公开网页信息 | `web_search` |
+| 地址/地点转经纬度 | `geocode` |
+| UI 操作 / 可视化 | `locate_features`、`zoom_to_map`、`view_scada`、`show_chart`、`render_junctions`、`view_history`、`apply_layer_style` |
+| 持久化渲染数据 | ①准备 { node_area_map } JSON → ②`store_render_ref` 存为受控 ref → ③`render_junctions` 渲染到前端 |
+
+**前端工具仅做显示，不返回数据**，不要假设其返回内容。
+
+## 执行约束
+
+1. 每次工具调用必须在 `reason` 字段填写具体理由
+2. `tjwater-cli` 输出为 JSON（`schema_version: tjwater-cli/v1`），`"ok": true` 成功，失败时检查 `error.code`
+3. 大结果集禁止完整读取，优先采样/截断/按字段读取
+4. 避免直接用 `Read` 或 `cat` 读取结果文件，尤其是大文件；优先用 `head`/`tail`/`rg` 截断查看，或用 Python 只向 stdout 输出精简 JSON，避免大文件冲击 stdin/stdout
+5. 无可用数据时不得编造结果
+6. 禁止使用 `task` 子代理；当前前端无法观测和干预子代理的具体工作过程
+7. Bash 始终运行在当前对话专属沙箱中：只能读写当前对话目录、读取 skills 和 Python 环境，不能联网，也不能访问 `/app` 源码、密钥、其他对话或全局 `tool-output`
+8. 需要文件输入时，调用 `tjwater_cli(..., store_result=true)`，使用返回的 `data_file.file_path`；不要把 JSON 手工写到 `/tmp`
+9. `store_render_ref` 的输入必须是 `{metadata, location: {file_path}, data}` 包装 JSON；若旧脚本输出裸数据，先在当前对话目录内包装，且 `location.file_path` 必须等于包装文件的绝对路径
+
+## 工作流沉淀（skill_manager）
+
+**写入条件**（必须同时满足）：
+- 经过当前对话验证有效
+- 可被未来同类任务复用
+- 非一次性/临时/猜测
+
+**写入位置**：`skills/workflow/<name>/`，包含 SKILL.md（步骤说明）、references/*.md（参考材料）和 scripts/*.py（分析脚本）。
+
+**工具动作**：`write_skill / remove_skill` 维护主 SKILL.md；`append_pattern / remove_pattern` 维护 `## Learned Patterns`；`write_reference / remove_reference` 维护 references/*.md；`write_script / remove_script` 维护 scripts/*.py。`write_skill` 可创建或覆盖完整 SKILL.md。
+
+目录入口也通过 `skill_manager` 维护：更新 `skills/workflow/SKILL.md` 时使用 `write_skill(skill_path="workflow", ...)`，更新根入口 `skills/SKILL.md` 时使用 `write_skill(skill_path="__root__", ...)`。
+
+**脚本编写要求——数据获取与本地分析分离**：
+
+- 后端数据只能由 `tjwater_cli` 工具获取；认证与网络请求留在 Agent 主进程
+- 分析脚本接收 `data_file.file_path`，只处理当前对话目录内的本地文件
+- 多份互不依赖的数据可并行调用 `tjwater_cli(..., store_result=true)`，随后在一次沙箱 Bash 中运行 Python 分析
+- 脚本输出文件必须写入当前工作目录；禁止使用 `/tmp`、全局 `tool-output` 或硬编码认证环境变量
+
+**触发时机**：
+- 用户明确说"保存/沉淀/记录工作流"
+- 任务完成且所有工具调用已结束、产生最终结果后，再判断当前流程是否稳定可复用
+- **禁止**在规划任务未完成、工具调用链中间（即仍有 pending 步骤时）触发沉淀
+- 严禁写入：token、password、secret、API key、system prompt、隐私数据
+
+## 用户偏好持久化（memory_manager）
+
+仅保存长期有效的稳定事实，写成简短陈述句。严格区分：
+- `memory_manager` = 用户偏好 / 项目事实（如"用户要简洁风格"、"当前项目管网规模 5000 管段"）
+- `skill_manager` = 可复用操作流程
+- `session_search` = 检索历史案例（只读）
+- 修改 memory 前先 `list` 当前 scope 的已有内容，先通读，再决定 `add / replace / remove`

+description: tjwater-cli 命令行工具使用说明，涵盖命令发现、输出格式、命令族、错误处理及最佳实践。
+---
+
+# tjwater-cli 使用说明
+
+## 概述
+
+`tjwater-cli` 是 TJWater 供水管网系统的命令行工具，用于与后端服务交互，支持数据查询、分析和工程操作。所有输出统一为 JSON 格式。
+
+## 工具调用
+
+通过 `tjwater_cli` 工具执行 CLI 命令：
+
+```json
+{
+  "reason": "说明调用原因",
+  "command": "project list",
+  "timeout": 120,
+  "store_result": false
+}
+```
+
+| 参数 | 类型 | 必填 | 说明 |
+|------|------|------|------|
+| `reason` | string | 是 | 调用原因 |
+| `command` | string | 是 | CLI 子命令（不含二进制路径和 `--auth-context`） |
+| `timeout` | number | 否 | 超时秒数，默认 120，大结果集建议 300+ |
+| `store_result` | boolean | 否 | 强制保存到当前对话目录并返回 `data_file.file_path`；分析脚本需要文件输入时设为 true |
+
+认证上下文（token、server、project、network）由内部桥接自动注入，无需手动传参。
+
+## 命令发现
+
+Agent 通过 `help` 动态发现可用命令，而非依赖硬编码清单。
+
+**重要：命令分为两类——触发动作与数据获取。**
+
+- **触发动作**（`simulation`、`analysis`）：向服务端发起计算请求，返回任务状态/ID，**不直接返回分析结果**。
+- **数据获取**（`data timeseries`）：所有计算结果（仿真压力、分析指标等）的唯一数据出口，需在触发动作完成后调用。
+
+```
+simulation/analysis → 触发计算 → 返回状态/任务ID
+                              ↓
+                  data timeseries → 获取计算结果
+```
+
+通过 `help` 发现命令：
+
+```
+tjwater-cli help                   → 一级命令清单（含 commands 数组和 summary）
+tjwater-cli help data timeseries   → data timeseries 的子命令与参数详情
+tjwater-cli help simulation        → simulation 的子命令与参数详情
+tjwater-cli help COMMAND           → 子命令与参数详情
+```
+
+`help` 返回 JSON 格式，Agent 可直接解析 `commands` 数组识别可用能力。
+
+**严禁猜测命令或参数！** 所有命令路径、子命令和参数（名称、类型、必填/可选）均以 `help` 输出为准。执行任何命令前，必须先通过 `help` 确认其存在及参数签名，禁止凭经验拼写。
+
+### 已知命令族
+
+| 命令族 | 典型子命令 | 用途 |
+|------|-----------|------|
+| `project` | `list`, `db-health` | 项目管理、数据库健康检查 |
+| `data` | `timeseries realtime links / nodes`, `timeseries scada query` | **时序数据查询**（实时/SCADA），所有分析结果的唯一获取渠道 |
+| `simulation` | 通过 `help simulation` 发现 | **触发水力仿真计算**（执行成功返回状态，实际结果需走 `data timeseries` 获取） |
+| `analysis` | 通过 `help analysis` 发现 | **触发分析计算**（执行成功返回状态，实际结果需走 `data timeseries` 获取） |
+| `net` | `list-pipes` | 管网拓扑查询 |
+| `help` | (无子命令) | 命令发现入口 |
+
+> 完整命令清单始终以 `tjwater-cli help` 实时输出为准。
+
+## 输出格式
+
+所有命令返回统一 JSON 结构：
+
+```json
+{
+  "schema_version": "tjwater-cli/v1",
+  "ok": true,
+  "data": { ... },
+  "error": {
+    "code": "COMMAND_NOT_FOUND",
+    "message": "详细错误描述"

+禁止完整读取超大结果集。优先使用：
+- 采样/截断参数（如 `--limit`、`--offset`）
+- `--field` 按字段过滤
+- `store_result=true` 后用沙箱 Python 脚本按字段读取
+
+## 错误码速查
+
+| error.code | 含义 | 来源 | 处理建议 |
+|------|------|------|------|
+| `UNAUTHENTICATED` | 缺少 access token | CLI `core.py:162` | 检查认证上下文注入 |
+| `SERVER_ERROR` | 后端返回 error 状态 | CLI `core.py:400` | 记录 `request_id`，结合后端日志排查 |
+| `REQUEST_TIMEOUT` | CLI 请求后端超时 | CLI `core.py:445` | 增大 `timeout` 参数或检查后端负载 |
+| `TIMEOUT` | bridge 层进程超时 | Agent `server.ts:199` | 增大 `tjwater_cli` 的 `timeout` 参数 |
+| `COMMAND_NOT_FOUND` | 命令/子命令不存在 | CLI `helping.py:300` | 执行 `help` 确认命令拼写 |
+| `INPUT_NOT_FOUND` | `--input` 文件不存在 | CLI `core.py:243` | 检查文件路径 |
+| `REQUEST_FAILED` | 网络连接失败 | CLI `core.py:453` | 检查服务端可达性 |
+| `AUTH_CONTEXT_INVALID` | 认证上下文格式错误 | CLI `core.py:111` | 检查 auth headers 格式 |
+
+## 最佳实践
+
+1. **禁止猜测命令** — 执行任何命令前必须先 `tjwater_cli(command="help ...")` 确认命令存在及参数签名，参数均已写在 help 中，禁止凭经验拼写
+2. **reason 必填** — 每次调用必须说明具体理由
+3. **触发后取数据** — `simulation`/`analysis` 仅触发计算，结果必须从 `data timeseries` 获取，勿将触发返回的状态信息当作分析结果
+4. **文件分析** — workflow 脚本需要文件时使用 `store_result=true`，不得从 Bash 直接联网调用 CLI
+5. **结果验证** — 始终检查 `ok` 字段，失败时先处理错误码再重试
+6. **大结果集** — 优先过滤/采样，不要一次性拉取全部数据
+7. **模拟时长控制** — 模拟（`simulation`）或方案模拟的 `--duration` 不宜过长，建议每次仿真时间跨度控制在一小时以内，避免计算耗时过长或结果数据量过大
+
+## 示例
+
+### 查询所有实时节点数据
+```json

+description: 基于实时水力数据的管网水力瓶颈识别与改造建议。复合评分法（流速×水头损失）定位瓶颈管段，输出分级改造方案。
+---
+
+# 水力瓶颈分析工作流
+
+## 概述
+
+本工作流通过复合评分法（流速分级 × 水头损失百分位）从全管网管道中识别水力瓶颈管段，并结合节点压力、管径、粗糙系数给出分级改造建议。
+
+适用场景：管网运行评估、管网改造优先级排序、泵站阀站运行诊断。
+
+## 评分方法论
+
+### 双维度复合评分
+
+| 维度 | 判定标准 | 分值 |
+|------|----------|------|
+| **流速** | >3.0 m/s = 极危 | 3 |
+|  | 2.0–3.0 m/s = 严重 | 2 |
+|  | 1.5–2.0 m/s = 偏高 | 1 |
+|  | <1.5 m/s = 正常 | 0 |
+| **水头损失** | >P90 = 严重 | 2 |
+|  | P80–P90 = 中度 | 1 |
+|  | <P80 = 正常 | 0 |
+
+**瓶颈判定**：`(流速≥1 且 水损≥1)` 或 `(流速≥2)` —— 即双侧超标或单侧流速严重。
+
+**复合评分** = 流速分值 + 水损分值（最高 5 分），按降序排列。
+
+### 辅助指标
+
+| 指标 | 阈值 | 含义 |
+|------|------|------|
+| 节点压力 < 20m | — | 低压区域，需增压 |
+| 节点压力 20–25m | — | 压力偏低 |
+| roughness > 130 | — | 管壁粗糙，建议内衬修复 |
+
+> ⚠️ **setting 字段无效**：`data timeseries realtime links` 返回的 `setting` 字段为无效值，不可用于阀门节流或水泵出口判定。若需确定阀门/泵状态，应通过 `network get-link-properties` 逐条查询。
+
+## 数据依赖
+
+| 步骤 | 命令 | 数据量 | 超时 | 关键字段 |
+|------|------|--------|------|----------|
+| ① 管道属性 | `network get-all-pipes-properties` | ~11.7MB / 91K条 | 120s | id, node1, node2, length, diameter, roughness |
+| ② 管道水力 | `data timeseries realtime links --start-time T --end-time T+15min` | ~39MB / 182K条 | 300s | id, flow, velocity, headloss, time |
+| ③ 节点压力 | `data timeseries realtime nodes --start-time T --end-time T+15min` | ~28MB / 176K条 | 300s | id, pressure, time |
+
+> **时间窗口说明**：模拟步长 15 分钟，查询窗口取 `T~T+15min` 可覆盖 1–2 个时间步。脚本内部按 `--target-time` 精确筛选目标时刻的记录。
+
+> **大结果集处理**：三份调用都使用 `store_result=true`，结果保存到当前对话的 `tool-data/` 目录。脚本直接读取每次返回的 `data_file.file_path`，不得访问全局 `tool-output/`。
+
+## 执行步骤
+
+### 第 1 步：拉取三份数据
+
+并行发起 3 个 `tjwater_cli` 调用（互不依赖）：
+
+```bash
+# ① 管道静态属性
+tjwater_cli(command="network get-all-pipes-properties", timeout=120, store_result=true)
+
+# ② 目标时刻管道水力数据
+tjwater_cli(command="data timeseries realtime links --start-time 2026-04-01T08:00:00+08:00 --end-time 2026-04-01T08:15:00+08:00", timeout=300, store_result=true)
+
+# ③ 目标时刻节点压力数据
+tjwater_cli(command="data timeseries realtime nodes --start-time 2026-04-01T08:00:00+08:00 --end-time 2026-04-01T08:15:00+08:00", timeout=300, store_result=true)
+```
+
+### 第 2 步：运行分析脚本
+
+```bash
+python3 <skill_dir>/scripts/bottleneck_analysis.py \
+  --pipe-props <data_file.file_path-①> \
+  --realtime <data_file.file_path-②> \
+  --node-pressures <data_file.file_path-③> \
+  --target-time '2026-04-01T08:00:00+08:00' \
+  --top 50 \
+  2>./bottleneck_report.txt
+```
+
+**脚本参数**：
+- `--pipe-props`：管道属性 JSON 文件路径（必填）
+- `--realtime`：实时管道水力 JSON 文件路径（必填）
+- `--node-pressures`：实时节点压力 JSON 文件路径（必填）
+- `--target-time`：目标时刻 ISO8601（必填，如 `2026-04-01T08:00:00+08:00`）
+- `--top`：输出 Top N 瓶颈管段（默认 100）
+
+**输出**：
+- **stderr**：文本摘要 + Top 30 表格（可重定向到文件查看）
+- **stdout**：完整 JSON 结果，包含 `summary` 和 `top_bottlenecks`（含每条的建议 `suggestions`）
+
+### 第 3 步：结果解读与分类
+
+按瓶颈严重程度和根因分类：
+
+| 类别 | 判定条件 | 优先处理方案 |
+|------|----------|--------------|
+| 🔴 极危 | 流速>3.0m/s 且 水损>P90 | 检查模型/扩容/分流 |
+| 🔵 串联瓶颈 | 连续多根瓶颈管段共享节点 | 统一规划扩径，一次性解除 |
+| 🟣 低压区 | 端节点压力<20m | 扩径 + 评估中途加压 |
+| 🟡 高粗糙度 | roughness>130 的瓶颈管段 | 内衬修复降阻 |
+| 🟢 短管异常 | length<10m 且 headloss>P95 | 检查模型是否存在局部阻塞 |
+
+### 第 4 步：可视化（可选）
+
+1. **地图定位**：将 Top N 瓶颈管段用 `locate_features` 高亮到地图
+2. **统计图表**：用 `show_chart` 展示管径分布柱状图 + 流速等级柱状图
+3. **样式渲染**：可对 pipes 图层按 velocity 或 headloss 属性做分层设色
+
+## 改造建议生成逻辑
+
+脚本自动为每条瓶颈管段生成建议，规则如下：
+
+```
+if velocity > 2.0 → "流速X.XXm/s过高，需扩容或分流"
+elif velocity > 1.5 → "流速X.XXm/s偏高"
+
+if headloss > P95 → "水头损失X.XXm(>P95)严重超标"
+elif headloss > P90 → "水头损失X.XXm(>P90)"
+
+if diameter < 100 → "管径Xmm偏小，建议扩径至≥150mm"
+elif diameter < 200 → "管径Xmm，评估扩容至250-300mm"
+
+if roughness > 130 → "粗糙系数X偏高，建议内衬修复"
+
+if min_pressure < 20 → "端节点压力X.Xm(<20m)，低压区域需增压"
+elif min_pressure < 25 → "端节点压力X.Xm偏低"
+
+if length < 0.01 and headloss > 0.5 → "短管高水损，检查是否存在模型异常或局部阻塞"
+```
+
+## 参考数据规模（实测）
+
+基于 91,000 管段 / 88,000 节点规模的管网模型：
+
+| 指标 | 实测值 |
+|------|--------|
+| 管道属性数据量 | 91,052 条 / ~11.7MB |
+| 实时管道数据量 | 182,108 条（2步）/ ~38.7MB |
+| 实时节点数据量 | 175,814 条（2步）/ ~28.2MB |
+| 分析脚本处理时间 | 约 10-20 秒 |
+| 典型瓶颈数量 | 50-100 条（占总管数 0.05%-0.1%） |
+
+## 已知限制
+
+- 水头损失百分位阈值（P80/P90）基于**全管网**统计，如果管网上游存在极端水损（如 400m+），会拉高整体 P 值，导致部分中高水损管段被漏判。极端场景下可考虑对水损做分位数裁剪（如排除 >P99.9 的离群值）后再计算 P80/P90。
+- **setting 字段不可用**：`data timeseries realtime links` 返回的 `setting` 值为无效数据，本工作流已移除所有基于 setting 的阀门节流 / 水泵出口判定。若需要此类判定，应通过 `network get-link-properties` 逐条获取属性中的 setting 作为替代。
+- 脚本读取全量 JSON 入内存，峰值内存约 200-300MB，需确保执行环境有足够内存。

+description: 基于实时水力模拟数据的水源追溯供水服务范围分区。通过管段流量确定水流方向，从水库BFS追溯服务节点，环网/零流量节点用无向拓扑补充分配，输出分区可视化。
+---
+
+# 供水服务范围分区工作流
+
+## 概述
+
+本工作流基于指定时刻的水力模拟结果，通过**流向追溯法**将全部管网节点分配到各水库的服务范围。核心思路：利用管段流量符号判定水流方向，构建有向图从水库逐级追溯，对环网和零流量节点用无向拓扑修正。
+
+适用场景：供水服务范围评估、DMA分区规划、多水源供水格局分析、管网调度策略评估。
+
+## 分区方法
+
+### 第一步：水流方向判定
+
+对于每条管段，根据实时流量 `flow` 判定水流方向：
+
+| flow 值 | 水流方向 | 说明 |
+|---------|----------|------|
+| `flow > 1e-6` | node1 → node2 | 正向流量 |
+| `flow < -1e-6` | node2 → node1 | 反向流量 |
+| `|flow| ≤ 1e-6` | 无方向 | 零流量，不参与有向追溯 |
+
+### 第二步：多源有向BFS
+
+1. 以每个水库为根节点，沿水流方向执行 BFS
+2. 遍历到的节点归属该水库的服务范围
+3. **先到先得**：一个节点首次被访问到的水库即为归属
+4. 预期覆盖 **85–90%** 节点
+
+### 第三步：无向拓扑修正
+
+有向BFS不可达节点（通常 10–15%）通过无向图邻近性补充分配：
+
+| 不可达原因 | 说明 |
+|------------|------|
+| 环状管网 | 水流回路中下游节点反向连回上游，有向遍历被阻断 |
+| 零流量管段 | `flow≈0` 的管段无方向，其下游节点断开 |
+| 多水源交汇 | 交汇区流向往复，非树状拓扑 |
+
+### 输出统计
+
+每个分区输出：
+- `node_count`：分区内节点总数
+- `total_demand`：总需水量（负数=净供水区）
+- `avg_pressure`/`min_pressure`/`max_pressure`：压力统计
+
+## 数据依赖
+
+| 步骤 | 命令 | 数据量 | 超时 | 关键字段 |
+|------|------|--------|------|----------|
+| ① 管道拓扑 | `network get-all-pipes-properties` | ~11.7MB / 91K条 | 120s | id, node1, node2 |
+| ② 水库属性 | `network get-all-reservoirs-properties` | ~小 | 120s | id, links |
+| ③ 管段流量 | `data timeseries realtime links --start-time T --end-time T+15min` | ~39MB / 182K条 | 300s | id, flow, time |
+| ④ 节点数据 | `data timeseries realtime nodes --start-time T --end-time T+15min` | ~28MB / 176K条 | 300s | id, pressure, actual_demand, time |
+
+> **时间窗口**：模拟步长 15 分钟，查询 T~T+15min 覆盖 1–2 个时间步。脚本按 `--target-time` 精确筛选。
+
+> **文件输入**：四份调用都使用 `store_result=true`，包括结果较小的水库属性。脚本读取每次返回的 `data_file.file_path`；文件都属于当前对话，禁止使用 `/tmp` 或全局 `tool-output/`。
+
+## 执行步骤
+
+### 第 1 步：并行拉取数据
+
+4 个 `tjwater_cli` 调用（互不依赖），可一次发起：
+
+```bash
+# ① 管道静态拓扑
+tjwater_cli(command="network get-all-pipes-properties", timeout=120, store_result=true)
+
+# ② 水库属性
+tjwater_cli(command="network get-all-reservoirs-properties", timeout=120, store_result=true)
+
+# ③ 目标时刻管段流量
+tjwater_cli(command="data timeseries realtime links --start-time 2026-04-01T08:00:00+08:00 --end-time 2026-04-01T08:15:00+08:00", timeout=300, store_result=true)
+
+# ④ 目标时刻节点数据
+tjwater_cli(command="data timeseries realtime nodes --start-time 2026-04-01T08:00:00+08:00 --end-time 2026-04-01T08:15:00+08:00", timeout=300, store_result=true)
+```
+
+### 第 2 步：运行分区脚本
+
+```bash
+python3 <skill_dir>/scripts/service_area_partition.py \
+  --pipe-props <data_file.file_path-①> \
+  --reservoirs <data_file.file_path-②> \
+  --links <data_file.file_path-③> \
+  --nodes <data_file.file_path-④> \
+  --target-time '2026-04-01T08:00:00+08:00' \
+  --output ./service_area_partition_wrapper.json
+```
+
+**脚本参数**：
+
+| 参数 | 说明 | 必填 |
+|------|------|------|
+| `--pipe-props` | 管道属性 JSON 文件路径 | 是 |
+| `--reservoirs` | 水库属性 JSON 文件路径 | 是 |
+| `--links` | 实时管段数据 JSON 文件路径 | 是 |
+| `--nodes` | 实时节点数据 JSON 文件路径 | 是 |
+| `--target-time` | 目标时刻 ISO8601 | 是 |
+| `--output` | 分区结果输出路径 | 是 |
+
+**输出**：
+- **stderr**：处理日志 + 各分区统计表格
+- **stdout**：紧凑 JSON 摘要（total_nodes, reservoirs, areas）
+- **文件**：符合 `store_render_ref` 要求的 `{metadata, location, data}` 包装 JSON，其中 `data` 包含 `node_area_map`、`area_ids`、`area_colors` 和分析元数据
+
+### 第 3 步：前端可视化
+
+```bash
+# 持久化分区结果
+store_render_ref(file_path=<output-file>)
+
+# 渲染节点分区
+render_junctions(render_ref="res-xxxxxxxx-xxxx-xx")
+
+# 定位水库
+locate_features(ids=[...], feature_type="reservoir")
+
+# 展示统计图表
+show_chart(title="各水源分区节点数/压力对比", chart_type="bar", ...)
+```
+
+## 参考数据规模
+
+基于 91,000 管段 / 88,000 节点规模的管网模型：
+
+| 指标 | 实测值 |
+|------|--------|
+| 管道拓扑数据量 | 91,052 条 |
+| 水库数量 | 13 个 |
+| 总节点数 | 87,907 |
+| 有向BFS分配节点 | ~76,900 (87.5%) |
+| 无向修正节点 | ~11,000 (12.5%) |
+| 分区覆盖率 | 100% |
+| 脚本处理时间 | ~15-30 秒 |
+| 峰值内存 | ~400-500MB |
+
+## 已知限制
+
+- **水库顺序敏感**：多源 BFS 中先遍历到的水库优先分配，不同水库启动顺序可能影响边界区域分配结果
+- **单时刻快照**：分区仅反映目标时刻的水力工况，不同时段的泵站启停、阀门切换可能导致分区边界变化
+- **零流量阈值**：`1e-6` 阈值过滤极低流量管段，若管网有长期小流量管段可能漏判方向

+# Repository Guidelines
+
+## Project Structure & Module Organization
+
+This repository is the internal TJWater agent service. Runtime TypeScript code is organized under `src/`; CLI-specific code is under `cli/src`; Node test files live in `node-tests/`. Agent extensions and OpenCode integration files are under `.opencode/`, including `.opencode/agents`, `.opencode/skills`, and `.opencode/tools`. Runtime data, session metadata, logs, and result references are stored under `data/` and `logs/` and should be treated as local/generated state.
+
+Deployment files are `Dockerfile`, `docker-compose.yml`, and `.gitea/workflows/package.yml`.
+
+## Build, Test, and Development Commands
+
+Use Bun for this project:
+
+```bash
+bun install
+bun run dev
+bun run check
+bun run test:cli
+bun run start
+```
+
+`bun run dev` starts `src/server.ts` in watch mode. `bun run check` runs TypeScript checks for the main project and `.opencode`. `bun run test:cli` runs Node CLI tests. `bun run start` starts the service without watch mode.
+
+## Coding Style & Naming Conventions
+
+Use TypeScript ESM and keep types explicit at module boundaries. Use two-space indentation, `camelCase` for functions and variables, `PascalCase` for classes/types, and kebab-case or descriptive lowercase names for scripts and data files. Prefer existing `src/` service, route, and runtime patterns before introducing new structure.
+
+## Testing Guidelines
+
+Tests use Node's built-in test runner for CLI coverage. Name test files with `.node.mjs` when using `node --test`, matching `node-tests/cli/*.node.mjs`. Add focused tests for CLI parsing, tool behavior, and session/runtime changes. Do not depend on mutable local files under `data/`.
+
+## Commit & Pull Request Guidelines
+
+History uses Conventional Commit messages such as `feat(tools): add search and map tools`, `fix(agent): warm up opencode on startup`, and `refactor(chat): ...`. Prefer `feat(scope):`, `fix(scope):`, or `refactor(scope):`.
+
+PRs should describe runtime behavior changes, list `bun run check` and any test commands run, and mention changes to `.opencode`, secrets, ports, or deploy workflow behavior.
+
+## Security & Configuration Tips
+
+Do not commit `.env`, logs, session transcripts, generated result references, or `node_modules/`. Keep registry and deploy credentials in Gitea secrets.
+
+Automatic approval for `glob` and `grep` must remain limited to canonical paths inside an explicit safe workspace subtree. Broad source-workspace searches, symlink escapes, external paths, and `.env`, ordinary `data/`, or `logs/` targets must stay interactive. The current session's canonical `data/conversation-workspaces/<conversation-id>/` directory is the only `data/` exception; access must still reject symlinks and every other conversation directory.

-# TJWaterAgent
+# TJWaterAgent 内部智能体服务
 
+`TJWaterAgent` 是 TJWater 内部版智能体服务，负责连接前端聊天界面、OpenCode 运行时、MCP 工具和 TJWater 后端 API。它面向内部研发与部署，保留完整的 Agent 编排、会话上下文、工具调用和运行时调试能力。
+
+## 主要能力
+
+- 提供 `POST /api/v1/agent/sessions/{session_id}/runs` SSE 聊天接口。
+- 以内嵌模式启动并预热 OpenCode 运行时。
+- 管理前端 `session_id` 与 OpenCode session 的映射。
+- 在服务端保存当前会话的用户 token、项目、network 和 trace 上下文。
+- 通过 `.opencode/tools` 和 MCP 工具驱动地图定位、图表、SCADA、历史数据和业务 API 调用。
+- 通过 `data/` 保存运行时会话元数据、结果引用和本地状态。
+
+## 目录结构

+logs/                 本地日志，禁止提交
+```
+
+仓库跟踪 `.opencode/skills/` 中经过评审的默认工作流基线；部署环境仍可通过持久化卷保留 `skill_manager` 在运行中沉淀的增量内容。默认基线不得包含真实客户数据、认证信息或本地执行产物。
+
+## 本地开发
+
+项目使用 Bun：
+
+```bash
+bun install
+bun run dev
+```
+
+`bun install` 会通过 `postinstall` 安装 `.opencode` 子目录依赖。`bun run dev` 以 watch 模式启动 `src/server.ts`，修改 `src/**`、`.opencode/**`、`opencode.json` 或 `.local.env` 后会自动重启。
+
+`cli/tjwater-cli` 是当前唯一的 TJWater 业务 CLI 入口，由 Bun 直接执行
+`cli/tjwater-cli.ts` 及 `cli/src/` 源码，并随 Agent 镜像一起交付，不需要
+Python 或 PyInstaller 构建步骤。
+
+## 常用命令
+
+```bash
+bun run check
+bun run contract:generate
+bun run test:api
+bun run test:cli
+bun run start
+bun run start:prod
+docker build -t tjwater-agent:local .
+```
+
+- `bun run check`：检查主项目和 `.opencode` 的 TypeScript 类型。
+- `bun run contract:generate`：生成 `contracts/agent-v1.openapi.json`。
+- `bun run test:api`：验证公开 REST 契约和聊天路由。
+- `bun run test:cli`：运行 `node-tests/cli/*.node.mjs`。
+- `bun run start`：直接启动服务。
+- `bun run start:prod`：先类型检查，再启动服务。
+
+## 运行模式
+
+当前运行时使用 OpenCode 稳定版 1.x CLI，并通过稳定版 SDK 的 `@opencode-ai/sdk/v2` HTTP 客户端访问运行时；这与 `opencode2` 及 `@opencode-ai/client` 的 2.0 beta 运行时不同。Embedded 模式由服务进程拉起本机 OpenCode：
+
+```bash
+OPENCODE_MODE=embedded
+TJWATER_API_BASE_URL=http://127.0.0.1:8000
+```
+
+当前仅支持 Embedded 模式，不支持连接外部 OpenCode server。
+
+## 认证续期与学习工具
+
+后端工具调用遇到即将过期的 access token 或首次 `401` 时，Agent 会通过当前 SSE 流发送 `credential_refresh_required`。前端使用服务端保存的 Keycloak refresh token 强制换取新 access token，再调用 `POST /api/v1/agent/sessions/{session_id}/credential-refreshes` 唤醒原工具调用。等待上限为 30 秒，同一会话的并发请求合并为一次续期，原调用最多重试一次；`403` 不触发续期。
+
+`memory_manager` 和 `skill_manager` 在 OpenCode 侧只保留内部 HTTP 桥，读取会话上下文和持久化数据的逻辑统一在 Agent 主进程中执行。长期记忆、自动学习和显式工具写入因此共享同一组 `MemoryStore`、`SkillStore` 和运行时会话上下文。
+
+本地可使用 `.local.env` 保存开发配置；系统环境变量优先级更高。
+
+服务会在 HTTP 端口开始监听前完成 OpenCode 健康检查、临时会话创建和工具目录加载。`GET /health` 返回 `ready: true` 与 `warmed_up: true` 时，表示冷启动预热已经完成。开发环境会输出各预热阶段的耗时。
+
+`opencode.json` 已启用 `experimental.continue_loop_on_deny`。用户拒绝权限请求后，OpenCode V1 会把拒绝结果交还给 Agent，让其尝试无需该权限的替代方案，而不是直接结束本轮执行。
+
+前端提供三种整体权限模式：“请求批准”只执行 OpenCode 明确允许的白名单，Shell 和写操作逐次交给用户确认；“自动批准”额外自动放行低风险业务工具、skill、沙箱 Shell，以及真实路径位于当前 conversation workspace 内且通过 realpath/symlink 校验的 read/edit/glob/grep；“始终允许”自动放行当前对话中所有未被 OpenCode 明确禁止的权限请求。自动放行统一使用单次批准，切换整体模式后立即恢复对应策略，不会写入持久授权。
+
+单次权限请求支持“允许一次”“保存授权”和“拒绝”。“保存授权”使用 OpenCode 的 `always` 回复，仅保存 OpenCode 为本次请求建议的权限范围，并只在当前 OpenCode 会话内生效。任意外部目录默认仍由静态配置禁止；`.env`、普通 `data/`、`logs/` 和其他对话目录保持禁止。真实聊天会话使用 `data/conversation-workspaces/<随机目录>/` 作为独立工作目录。普通 `rm <文件>`、`rmdir` 和非强制递归删除可在沙箱内执行，`rm -rf`/`rm -fr` 及等价的递归强制删除形式会在执行前拒绝。
+
+OpenCode 的内置 Bash 由同名自定义工具覆盖。命令经内部鉴权路由进入独立子进程，切换到专用非 root UID 后应用 Landlock 文件规则和 seccomp 网络规则：当前 conversation workspace 可读写，系统/Python/skills 只读，其他应用文件、其他对话和全局 `tool-output` 不可见；IPv4/IPv6 TCP 与 UDP socket 均被拒绝。启动时会探测 Landlock ABI（要求 ≥4）和 libseccomp，失败时 Agent 直接启动失败，不会回退到未沙箱化 Shell。Shell 环境不包含模型 key、内部 token 或用户 access token，`HOME`、`TMPDIR` 和 Python 缓存均位于当前对话目录。
+
+`store_render_ref` 只会从当前对话绑定的工作目录导入包装格式 JSON；工作区根目录固定为项目内的 `./data/conversation-workspaces`，以确保 OpenCode 能继续发现项目配置和工具。文件必须包含 `metadata`、`location.file_path` 和 `data`，且真实路径不能越出当前对话目录；单文件默认上限为 128 MiB，成功导入后只删除这一份源包装文件。升级前已经存在的会话没有独立工作目录，需要新建对话后才能使用该导入能力。
+
+CLI 桥接层对 stdout 设置独立的 128 MiB 硬上限（`MAX_CLI_OUTPUT_BYTES`）；stderr 最多保留 256 KiB（`MAX_CLI_STDERR_BYTES`），超出后截断但不会终止 CLI。`MAX_INLINE_RESULT_BYTES`（默认 12000 字节）仅决定内联还是落盘：较大结果写入当前对话的 `tool-data/` 并返回 `data_file.file_path`，不会因为超过 12000 字节杀掉 CLI；分析脚本需要文件输入时可由 `tjwater_cli(store_result=true)` 强制落盘小结果。会话暂存数据不自动删除。OpenCode 自身为其他工具生成的全局 `tool-output` 仍按 `RESULT_REF_TTL_HOURS`（默认 7 天）清理，但沙箱命令不能访问该目录。
+
+## 配置与安全
+
+不要提交 `.env`、`.local.env`、`data/`、`logs/`、会话记录、模型输出、访问令牌或 `node_modules/`。部署凭据、镜像仓库账号和 webhook 地址应放在 Gitea secrets 或部署环境变量中。
+
+## 发布
+
+Gitea 包工作流位于 `.gitea/workflows/package.yml`。发布前至少运行：
+
+```bash
+bun run check
+```
+
+如修改 CLI 或工具调用逻辑，同时运行：
+
+```bash
+bun run test:cli
+```
