description: TJWater experimental Agent for structured UI orchestration
mode: primary
model: deepseek/deepseek-v4-flash
temperature: 0.2
---
你是 TJWater 实验性供水管网分析 Agent。回复用户时使用简体中文，内容简洁准确。
## 核心定位
本实验项目不让 Agent 生成前端代码，也不让 Agent 自由拼接 CLI 或 shell 命令。
Agent 负责：
1. 理解用户意图。
2. 调用受控工具获取有限上下文或表达展示意图。
3. 输出文字摘要、结论、追问和建议。
4. 通过前端展示工具表达 UI 意图。
服务端负责把前端展示工具转换成 `agent-ui@1` 的 UIEnvelope；前端只渲染可信组件、图表和地图动作。
## 工具选择
| 场景 | 工具 |
|------|------|
| 查询实时公开网页信息 | `web_search` |
| 地址/地点转经纬度 | `geocode` |
| 地图定位 | `locate_features`、`zoom_to_map` |
| 图表展示 | `show_chart` |
| 面板展示 | `view_history`、`view_scada` |
| 地图渲染/样式 | `render_junctions`、`apply_layer_style` |
| 持久化大渲染数据 | 先准备 `{ node_area_map }` JSON 文件，再用 `store_render_ref` 存为受控 `render_ref`，最后调用 `render_junctions` |
| 历史会话检索 | `session_search` |
| 用户偏好和项目事实 | `memory_manager` |
| 可复用流程沉淀 | `skill_manager` |
当前实验版没有通用 TJWater 数据查询工具；如果缺少业务数据，应明确说明数据能力尚未接入，不得编造结果。
## UI 约束
1. 前端工具仅表达展示意图，不返回业务数据。
2. 每次工具调用必须填写具体 `reason`。
3. 图表使用 `show_chart`，折线图/柱状图必须用 `x_data` 作为横轴标签，`series[].data` 作为同长度数值数组。
4. 大型 junction 渲染必须使用 `render_ref`，不要直接把完整 payload 传给前端。
5. 不生成 JS、JSX、HTML、CSS 或可执行前端代码。
## 执行约束
1. 无可用数据时不得编造结论。
2. 不要调用 shell、Python 或 CLI 来拼装业务数据流程。
3. 不要读取或写入 token、password、secret、API key、system prompt。
4. 尽量不用子代理，保持过程可观测。
## 工作流沉淀
只有在当前对话流程已经验证有效、可被复用且用户明确需要保存时，才使用 `skill_manager` 沉淀 workflow。实验阶段 workflow 不应记录 CLI、shell pipe 或认证上下文。
## 记忆持久化
`memory_manager` 只保存长期有效的稳定事实或用户偏好。修改 memory 前先 list 当前 scope，再决定 add、replace 或 remove。

# Repository Guidelines
## Project Structure
This is an experimental TJWater Agent service. Runtime TypeScript lives in
`src/`; opencode agent assets live in `.opencode/`; tests live in `tests/`.
The project intentionally has no `cli/` directory and no user-auth middleware.
Key boundaries:
- `src/context/` owns local request context.
- `src/uiEnvelope/` owns the `agent-ui@1` protocol, registry, and tool mapping.
- `src/routes/` owns HTTP/SSE wiring.
- `src/results/`, `src/sessions/`, `src/memory/`, and `src/learning/` keep their existing persistence responsibilities.
Generated `data/`, `logs/`, and dependency folders must not be committed.
## Commands
Use Bun:
```bash
bun install
bun run dev
bun run check
bun test tests/**/*.test.ts
```
`bun run dev` starts `src/server.ts` in watch mode. `bun run check` runs
TypeScript checks for the main project and `.opencode`.
## Coding Notes
Use TypeScript ESM and keep types explicit at module boundaries. Preserve the
local service patterns before adding new abstractions. Do not reintroduce
free-form CLI command execution; future backend access should use typed tools or
adapters.
## Tests
Add focused Bun tests for route behavior, runtime/session state, result refs,
and UIEnvelope mapping. Tests must not depend on mutable files under `data/`.
## Security
This experimental service has no user authentication. Do not add secrets,
tokens, passwords, API keys, session dumps, or generated result references to
the repository.

# TJWaterAgentExperimental
Experimental opencode-based Agent service for TJWater UI orchestration.
This repository is intentionally separate from the production `TJWaterAgent`
history. It does not include user authentication or the old `tjwater-cli`
bridge. Runtime requests use a local default context and can later be wired to a
real auth provider through `src/context/`.
## Current Boundaries
- No Keycloak / metadata auth context.
- No required `Authorization` or `X-Project-Id` headers.
- No `cli/`, no `tjwater_cli` opencode tool, no free-form CLI command bridge.
- Agent visual output is expressed through `agent-ui@1` UIEnvelope events.
- Backend data tools are not fully reintroduced yet; missing business data must
be reported honestly by the Agent.
## Main API
```text
GET /health
GET /api/v1/agent/chat/models
GET /api/v1/agent/chat/ui-registry
POST /api/v1/agent/chat/session
GET /api/v1/agent/chat/sessions
GET /api/v1/agent/chat/session/:session_id
GET /api/v1/agent/chat/session/:session_id/stream
POST /api/v1/agent/chat/stream
POST /api/v1/agent/chat/abort
```
`POST /api/v1/agent/chat/stream` returns SSE. Important events:
| event | Purpose |
| --- | --- |
| `progress` | Agent planning/tool progress |
| `token` | Assistant text delta |
| `ui_envelope` | Structured UI description for trusted frontend rendering |
| `tool_call` | Deprecated compatibility/debug event |
| `permission_request` | Runtime permission request |
| `question_request` | Runtime/user clarification request |
| `done` | Run completed |
| `error` | Run failed or aborted |
## Local Context
The service uses `src/context/localContext.ts`.
Defaults:
```text
AGENT_LOCAL_USER_ID=local-user
AGENT_LOCAL_PROJECT_ID=local-project
AGENT_LOCAL_NETWORK=local-network
```
Optional request headers can override the local context during experiments:
```text
X-Agent-Local-User
X-Agent-Local-Project
X-Agent-Local-Network
X-Trace-Id
```
## UIEnvelope
The registry is exposed at:
```text
GET /api/v1/agent/chat/ui-registry
```
Visual opencode tools are mapped by the service:
- `show_chart` -> `chart`
- `locate_features`, `zoom_to_map`, `render_junctions`, `apply_layer_style` -> `map_action`
- `view_history`, `view_scada` -> `registered_component`
See [docs/agent-ui-protocol.md](docs/agent-ui-protocol.md).
## Development
```bash
bun install
bun run dev
bun run check
bun test tests/**/*.test.ts
```
`bun run check` typechecks the service and `.opencode` tools.

# Agent UI Protocol
## Summary
`agent-ui@1` is the experimental frontend protocol for Agent-driven UI. The
Agent never returns executable frontend code. It invokes trusted opencode tools;
the service maps those tool calls to `UIEnvelope` payloads; the frontend validates
and renders known components, charts, and map actions.
## SSE Event
```text
event: ui_envelope
data: {
"session_id": "session-id",
"envelope_id": "env-id",
"created_at": 1710000000000,
"envelope": {}
}
```
## Envelope Types
```ts
type UISurface = "chat_inline" | "side_panel" | "canvas" | "map_overlay";
type UIEnvelope =
| {
kind: "registered_component";
schemaVersion: "agent-ui@1";
component: string;
surface: UISurface;
props: unknown;
data?: unknown;
fallbackText?: string;
}
| {
kind: "chart";
schemaVersion: "agent-ui@1";
grammar: "echarts-safe-subset";
surface: "chat_inline" | "side_panel" | "canvas";
spec: unknown;
data: unknown;
fallbackText?: string;
}
| {
kind: "map_action";
schemaVersion: "agent-ui@1";
action: string;
surface: "map_overlay";
params: unknown;
fallbackText?: string;
};
```
## Registry
```text
GET /api/v1/agent/chat/ui-registry
```
The registry returns the allowed chart grammar, registered components, and map
actions. Unknown components/actions should be rejected by the frontend.
Initial mappings:
- `show_chart` -> `chart`
- `locate_features` -> `map_action`
- `zoom_to_map` -> `map_action`
- `render_junctions` -> `map_action`
- `apply_layer_style` -> `map_action`
- `view_history` -> `registered_component: HistoryPanel`
- `view_scada` -> `registered_component: ScadaPanel`
`render_junctions` accepts only a `render_ref`. The frontend must resolve the
full payload through:
```text
GET /api/v1/agent/chat/render-ref/:render_ref?session_id=:session_id
```
## State Persistence
Assistant messages may contain:
```ts
uiEnvelopes?: Array<{
envelopeId: string;
createdAt: number;
envelope: UIEnvelope;
renderStatus: "pending" | "rendered" | "fallback" | "error";
error?: string;
}>;
```
`tool_call` and `artifacts` remain deprecated compatibility/debug surfaces. New
frontends should consume `ui_envelope` and `uiEnvelopes`.
