+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
+
+## 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
+
+## 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——优先用 pipe 串联**：
+
+workflow skill 脚本应尽量用 shell pipe 在一次 subprocess 调用中串联多个 CLI 命令。减少 tool calling 次数，提升执行效率。
+
+```python
+import subprocess, os
+
+# env dict 仅用于当前子进程，不污染 os.environ，多用户安全
+env = {**os.environ,
+       "TJWATER_SERVER": auth["server"],
+       "TJWATER_ACCESS_TOKEN": auth["access_token"], ...}
+
+# 好：一次 shell 调用，pipe 串联
+cmd = "tjwater-cli net list-pipes | jq '...' | xargs tjwater-cli analysis calc"
+result = subprocess.run(cmd, shell=True, env=env, capture_output=True, text=True)
+
+# 差：多次 subprocess.run
+step1 = subprocess.run(["tjwater-cli", "net", "list-pipes"], ...)
+step2 = subprocess.run(["tjwater-cli", "analysis", "calc"], ...)
+```
+
+管道场景下用子进程隔离的 env dict 传认证，释放 stdin 给管道数据流。不修改全局 `os.environ`。认证 JSON 由内部桥接注入，脚本不硬编码。
+
+CLI **不增加** `--input/--output`，数据转换由 `jq`/`xargs` 在 shell 管道中完成。
+
+**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`

+# 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 workspace-root searches, symlink escapes, external paths, and `.env`, `data/`, or `logs/` targets must stay interactive.

-# 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
+
+```text
+src/                  服务端 TypeScript 源码
+src/routes/           HTTP 路由
+src/chat/             聊天流和 SSE 事件适配
+src/runtime/          OpenCode 运行时管理
+src/session/          会话映射和运行上下文
+src/mcp/              MCP 服务与工具桥接
+cli/                  Agent 使用的 TypeScript 后端 API CLI
+.opencode/agents/    Agent prompt 和模型行为配置
+.opencode/tools/     OpenCode 自定义工具
+.opencode/skills/    可复用分析工作流
+node-tests/           Node CLI 测试
+data/                 本地运行时数据，禁止提交
+logs/                 本地日志，禁止提交
+```
+
+## 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，其他权限请求逐次交给用户确认；“自动批准”额外自动放行低风险业务工具、skill，以及真实路径位于工作区安全子树且不涉及 `.env`、`data/`、`logs/` 的 glob/grep；工作区根目录的宽泛搜索仍需确认。“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` 的直接访问以及通过结构化读写工具访问普通 `data/`、`logs/` 路径仍保持禁止。真实聊天会话使用 `data/conversation-workspaces/<随机目录>/` 作为独立工作目录，结果导入只能读取当前对话目录。普通 `rm <文件>` 仍可审批执行，常见的 `rm -rf`/`rm -fr` 递归强制删除形式会被静态拒绝。
+
+`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）只控制 OpenCode 的内联阈值，较大结果由 OpenCode 写入标准 `tool-output` 目录。Agent 启动时及后续定期清理其中超过 `RESULT_REF_TTL_HOURS`（默认 7 天）的 `tool_*` 文件。
+
+## 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
+```
