# Smart Support # Smart Support
AI 客服行动层框架。粘贴你的 API获得一个能执行真实操作的智能客服。 AI customer support action layer. Paste your API spec, get an AI agent that executes real actions.
## 问题 ## The Problem
现有客服工具(ZendeskIntercomAda)擅长回答 FAQ但自动化率卡在 20-30%。剩下 70% 的工单需要人工登录内部系统,手动查订单、取消订单、发优惠券。 Existing support tools (Zendesk, Intercom, Ada) answer FAQs well but automation
rates stall at 20-30%. The remaining 70% of tickets require agents to manually
log into internal systems to look up orders, cancel orders, issue coupons.
Smart Support 是补全这个缺口的「行动层」。它不替代现有客服平台,而是让 AI 能直接调用内部系统完成操作。 Smart Support fills that gap as the "action layer" -- it does not replace your
existing support platform, it enables AI to directly call your internal systems.
## 工作原理 ## How It Works
``` ```
客户消息 → Chat UI FastAPI WebSocket LangGraph Supervisor → 专业 Agent MCP Tools → 你的内部系统 User message -> Chat UI -> FastAPI WebSocket -> LangGraph Supervisor -> Specialist Agent -> MCP Tools -> Your systems
| |
Agent 注册表 interrupt() Agent Registry interrupt()
(YAML 配置) (人工确认) (YAML config) (human approval)
|
PostgresSaver PostgresSaver
(会话状态持久化) (session persistence)
``` ```
1. 客户在聊天界面发送消息 1. User sends a message in the chat UI.
2. LangGraph Supervisor 分析意图,路由到对应的专业 Agent 2. LangGraph Supervisor classifies intent and routes to the right agent.
3. Agent 通过 MCP 协议调用你的内部系统(查订单、取消订单、发折扣... 3. Agent calls your internal systems via MCP tools.
4. 涉及写操作时,自动触发人工确认流程 4. Write operations trigger a human-in-the-loop approval gate.
5. 所有操作全程记录,支持回放和分析 5. All operations are logged with full replay and analytics.
## 核心特性 ## Key Features
- **多 Agent 协作** - 不同操作由不同 Agent 处理,各自拥有独立的权限边界和工具集 - **Multi-agent routing** -- each operation goes to a specialist agent with its own tools and permissions
- **即插即用** - 粘贴 OpenAPI 规范 URL,自动生成 MCP 工具和 Agent 配置 - **Zero-config import** -- paste an OpenAPI 3.0 URL, agents are generated automatically
- **人工确认** - 所有写操作(取消、退款、修改)需要人工审批,读操作直接执行 - **Human-in-the-loop** -- all write operations (cancel, refund, modify) require approval; reads execute immediately
- **会话上下文** - 支持多轮对话Agent 能理解「取消那个订单」这样的指代 - **Session context** -- multi-turn conversation with persistent state across reconnects
- **实时流式输出** - WebSocket 双向通信,逐 token 流式返回 - **Real-time streaming** -- WebSocket token streaming with live tool call visibility
- **对话回放** - 逐步查看 Agent 决策过程、工具调用和返回结果 - **Conversation replay** -- step-by-step audit trail of every agent decision
- **数据分析** - 解决率、Agent 使用率、升级率、每次对话成本 - **Analytics dashboard** -- resolution rate, agent usage, escalation rate, cost per conversation
- **YAML 驱动配置** - Agent 定义、人设、垂直模板全部通过 YAML 配置 - **YAML-driven config** -- agents, personas, and vertical templates in a single file

## OpenAPI 自动接入 ## API Endpoints
不需要手动写 MCP 连接器。粘贴你的 API 规范 URL | Method | Path | Description |
|--------|------|-------------|
| WS | `/ws` | Main WebSocket chat endpoint |
| GET | `/api/health` | Health check |
| GET | `/api/conversations` | List conversations |
| GET | `/api/replay/{thread_id}` | Replay conversation |
| GET | `/api/analytics` | Analytics summary |
| POST | `/api/openapi/import` | Import OpenAPI spec |
| GET | `/api/openapi/jobs/{id}` | Check import job status |
1. 框架解析 OpenAPI 3.0 规范 ## Security
2. LLM 自动分类每个端点(读/写、客户参数、Agent 分组)
3. 运维人员审核分类结果
4. 自动生成 MCP 服务器 + Agent YAML 配置
5. 新工具立即可用
## 安全设计 - **SSRF protection** -- OpenAPI import blocks private IPs and metadata service URLs
- **Input validation** -- messages validated for size (32 KB), content length (10 KB), thread ID format
- **Rate limiting** -- 10 messages per 10 seconds per session
- **Audit trail** -- every tool call logged with agent, params, result, timestamp
- **Permission isolation** -- each agent only accesses its configured tools
- **Interrupt TTL** -- unanswered approval prompts expire after 30 minutes
- **人工确认** - 所有写操作需要客户或运维人员批准 ## Running Tests
- **SSRF 防护** - OpenAPI URL 导入时屏蔽内网地址和 DNS 重绑定攻击
- **操作审计** - 每个操作记录 Agent、参数、结果、时间戳
- **权限隔离** - 每个 Agent 只能访问其配置的工具集
- **中断超时** - 30 分钟未确认的操作自动取消,防止过期审批
## 开发阶段 ```bash
cd backend
pytest --cov=app --cov-report=term-missing
```
| 阶段 | 周期 | 内容 | Coverage is enforced at 80%+.
|------|------|------|
| Phase 1 | 第 1-3 周 | 核心框架Chat UI + Supervisor + Agent 注册表 + 中断流程 |
| Phase 2 | 第 3-4 周 | 多 Agent 路由 + Webhook 升级 + 垂直模板 |
| Phase 3 | 第 4-6 周 | OpenAPI 自动发现 + MCP 服务器生成 + SSRF 防护 |
| Phase 4 | 第 6-7 周 | 对话回放 + 数据分析仪表盘 |

# Agent Configuration Guide
## Overview
Smart Support agents are defined in `backend/agents.yaml`. Each agent is a
specialist with a specific role, permission level, and set of tools it can call.
## agents.yaml Structure
```yaml
agents:
- name: order_agent
description: "Handles order status, tracking, and cancellations."
permission: write
tools:
- get_order_status
- cancel_order
personality:
tone: friendly
greeting: "I can help with your order. What is your order number?"
escalation_message: "I'm escalating this to a human agent now."
- name: refund_agent
description: "Processes refund requests."
permission: write
tools:
- process_refund
- check_refund_eligibility
personality:
tone: empathetic
greeting: "I'm the refund specialist. How can I help?"
escalation_message: "I need to escalate this refund request."
- name: general_agent
description: "Answers general questions and FAQs."
permission: read
tools:
- search_faq
- fallback_respond
```
## Fields
### `name` (required)
Unique identifier used for routing. Must be alphanumeric with underscores.
### `description` (required)
Plain-text description of what this agent handles. Used by the supervisor to route
user messages to the right agent. Be specific.
### `permission` (required)
Controls the interrupt threshold:
- `read` -- no interrupt required. Agent can act immediately.
- `write` -- requires human approval via interrupt before executing tools.
- `admin` -- requires human approval and is logged for audit.
### `tools` (required)
List of tool names this agent can use. Tools are registered in the agent factory.
Each tool name must match a registered LangChain tool.
### `personality` (optional)
Customizes agent behavior:
- `tone` -- `friendly`, `formal`, `empathetic`, `technical`
- `greeting` -- Opening message injected at session start.
- `escalation_message` -- Message sent when the agent escalates.
## Built-in Templates
Use `TEMPLATE_NAME` environment variable to load a pre-built agent configuration:
| Template | Description |
|----------|-------------|
| `ecommerce` | Orders, refunds, shipping, product questions |
| `saas` | Account management, billing, technical support |
| `generic` | General-purpose FAQ and escalation |
Example:
```bash
TEMPLATE_NAME=ecommerce uvicorn app.main:app
```
## Adding New Agents
1. Add agent definition to `agents.yaml`.
2. Register any new tools in `backend/app/agents/`.
3. Restart the backend.
The supervisor will automatically route to the new agent when the user's intent
matches the agent's description.
## Agent Routing Logic
1. User sends a message.
2. The LLM supervisor classifies the intent against all agent descriptions.
3. If unambiguous, the matching agent is invoked directly.
4. If ambiguous (multiple plausible agents), the system asks a clarification question.
5. If multi-intent, agents are invoked sequentially.
## Escalation
Any agent can trigger escalation by calling the `escalate` tool. This:
1. Sends a webhook notification (if `WEBHOOK_URL` is configured).
2. Marks the conversation with `resolution_type = escalated`.
3. Sends the agent's `escalation_message` to the user.

# Smart Support -- Demo Script
## Overview
This script walks through a live demonstration of Smart Support, showcasing
multi-agent routing, human-in-the-loop interrupts, conversation replay,
and the analytics dashboard.
## Prerequisites
- Docker and Docker Compose installed
- API key for one of: Anthropic, OpenAI, or Google
## Setup (5 minutes)
### 1. Start the stack
```bash
cp .env.example .env
# Edit .env and add your ANTHROPIC_API_KEY (or other provider key)
docker compose up -d
```
Wait for all services to be healthy:
```bash
docker compose ps
# All services should show "healthy" or "running"
```
### 2. Seed demo data (optional)
```bash
docker compose exec backend python fixtures/demo_data.py
```
### 3. Open the app
Navigate to http://localhost in your browser.
---
## Demo Flow
### Scene 1: Basic Chat (2 minutes)
1. Open the Chat tab (default).
2. Send: **"What is the status of order 12345?"**
- Observe the `tool_call` indicator appear in the sidebar (order_agent calling `get_order_status`).
- The agent responds with order status.
3. Send: **"Can you cancel that order?"**
- The system detects a write operation and shows an **Interrupt Prompt**.
- Click **Approve** to confirm the cancellation.
- The agent confirms cancellation.
Key points to highlight:
- Real-time token streaming (words appear as they are generated)
- Tool call visibility (transparency into what the agent is doing)
- Human-in-the-loop confirmation for write operations
### Scene 2: Multi-Agent Routing (2 minutes)
1. Start a new browser tab (new session) or clear session storage.
2. Send: **"I need to track my order AND request a refund for a previous order"**
- The supervisor detects two intents: `order_agent` and `refund_agent`.
- Both agents run in sequence.
- Two interrupt prompts may appear if both operations are write-level.
Key points to highlight:
- Intent classification detecting multiple actions
- Automatic routing to appropriate specialist agents
- Sequential execution with confirmation gates
### Scene 3: Conversation Replay (2 minutes)
1. Click the **Replay** tab.
2. The conversation list shows all sessions, including the ones just conducted.
3. Click any thread to see the detailed step-by-step replay.
4. Expand a `tool_call` step to see the parameters and result.
Key points to highlight:
- Full audit trail of every agent action
- Expandable params/result for debugging
- Pagination for long conversations
### Scene 4: Analytics Dashboard (2 minutes)
1. Click the **Dashboard** tab.
2. Select the **7d** range.
3. Point out:
- Total conversations and resolution rate
- Agent usage breakdown (which agents handled how many messages)
- Interrupt stats (approved vs. rejected vs. expired)
- Cost and token usage
Key points to highlight:
- Operational visibility into agent performance
- Cost tracking per conversation/agent
- Resolution and escalation rates
### Scene 5: OpenAPI Import (2 minutes)
1. Click the **API Review** tab.
2. Paste the URL: `http://localhost:8000/openapi.json` (or the sample API URL)
3. Click **Import**.
4. Watch the job status update from `pending` to `processing` to `done`.
5. Review the classified endpoints table.
6. Edit the `access_type` for a sensitive endpoint (e.g., change `read` to `write`).
7. Click **Approve & Save**.
Key points to highlight:
- Zero-configuration discovery: paste a URL, get an agent
- AI-powered classification of endpoint sensitivity
- Human review gate before any endpoints go live
---
## Troubleshooting
**WebSocket shows "disconnected":**
- Check that the backend container is running: `docker compose logs backend`
- Verify port 8000 is not blocked
**No LLM responses:**
- Confirm your API key is set in `.env`
- Check backend logs: `docker compose logs backend`
**Database errors:**
- Run: `docker compose restart backend`
- If tables are missing: `docker compose exec backend python -c "import asyncio; from app.db import *; ..."`

# Deployment Guide
## Docker Compose (Recommended)
### Prerequisites
- Docker Engine 24+
- Docker Compose v2
### Quick Start
```bash
git clone <repo-url>
cd smart-support
# Configure environment
cp .env.example .env
# Edit .env: set ANTHROPIC_API_KEY (or OPENAI_API_KEY / GOOGLE_API_KEY)
# Start all services
docker compose up -d
# Verify health
docker compose ps
curl http://localhost/api/health
```
The app is available at http://localhost (frontend) and http://localhost:8000 (backend API).
### Services
| Service | Port | Description |
|---------|------|-------------|
| postgres | 5432 | PostgreSQL 16 database |
| backend | 8000 | FastAPI + LangGraph backend |
| frontend | 80 | React SPA served by nginx |
### Stopping
```bash
docker compose down # Stop services, keep data
docker compose down -v # Stop services and delete database volume
```
## Production Considerations
### Environment Variables
Set these in production (never commit secrets):
| Variable | Required | Description |
|----------|----------|-------------|
| `POSTGRES_PASSWORD` | Yes | Strong random password |
| `ANTHROPIC_API_KEY` | Yes* | LLM provider API key |
| `LLM_PROVIDER` | Yes | `anthropic`, `openai`, or `google` |
| `LLM_MODEL` | Yes | Model name for your provider |
| `WEBHOOK_URL` | No | Escalation notification endpoint |
| `SESSION_TTL_MINUTES` | No | Session timeout (default: 30) |
*Or `OPENAI_API_KEY` / `GOOGLE_API_KEY` depending on `LLM_PROVIDER`.
### HTTPS
For production, place a reverse proxy (nginx, Caddy, or a load balancer) in
front of the frontend container and configure TLS termination there.
The WebSocket endpoint at `/ws` must be proxied with `Upgrade: websocket` headers.
The frontend nginx.conf handles this internally for the backend connection.
Example Caddy configuration:
```
example.com {
reverse_proxy localhost:80
}
```
### Database Backups
```bash
# Backup
docker compose exec postgres pg_dump -U smart_support smart_support > backup.sql
# Restore
cat backup.sql | docker compose exec -T postgres psql -U smart_support smart_support
```
### Scaling
The backend is stateless (session state is in PostgreSQL via LangGraph's
PostgresSaver). You can run multiple backend replicas behind a load balancer.
The WebSocket connections are session-specific. Use sticky sessions or a shared
session backend if load balancing WebSockets across multiple instances.
## Manual / Development Setup
### Backend
```bash
cd backend
python -m venv .venv
source .venv/bin/activate # Windows: .venv\Scripts\activate
pip install -e ".[dev]"
# Set environment variables
cp .env.example .env
# Edit .env
# Start database
docker compose up postgres -d
# Run backend
uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload
```
### Frontend
```bash
cd frontend
npm install
npm run dev # Dev server on http://localhost:5173
```
### Running Tests
```bash
cd backend
pytest --cov=app --cov-report=term-missing
```
## Health Checks
### Backend health
```http
GET /api/health
```
Response:
```json
{"status": "ok", "version": "0.5.0"}
```
### WebSocket health
Connect to `ws://localhost:8000/ws` and send:
```json
{"type": "message", "thread_id": "health-check", "content": "ping"}
```
A `message_complete` or `error` response confirms the WebSocket is alive.

# OpenAPI Auto-Discovery Guide
## Overview
Smart Support can automatically generate AI agents from any OpenAPI 3.0 specification.
Import a URL, review the AI-classified endpoints, approve, and your agents are live.
## How It Works
1. **Import** -- Provide a URL to an OpenAPI 3.0 spec (JSON or YAML).
2. **Parse** -- The system downloads and parses the spec.
3. **Classify** -- An LLM classifies each endpoint's:
- `access_type`: `read`, `write`, or `admin`
- `agent_group`: which specialist agent should handle this endpoint
4. **Review** -- You inspect and edit the classifications in the UI.
5. **Approve** -- Approved endpoints are registered as tools on the appropriate agents.
## Using the UI
1. Navigate to the **API Review** tab.
2. Paste your OpenAPI spec URL into the import form.
3. Click **Import**.
4. Wait for the job to complete (status: `pending` -> `processing` -> `done`).
5. Review the endpoint table:
- Edit `access_type` if the AI misclassified sensitivity.
- Edit `agent_group` to reassign an endpoint to a different agent.
6. Click **Approve & Save** when satisfied.
## Using the REST API
### Submit an import job
```http
POST /api/openapi/import
Content-Type: application/json
{
"url": "https://api.example.com/openapi.yaml"
}
```
Response:
```json
{
"success": true,
"data": { "job_id": "abc123", "status": "pending" }
}
```
### Poll job status
```http
GET /api/openapi/jobs/{job_id}
```
### Get job results
```http
GET /api/openapi/jobs/{job_id}/result
```
### Approve job
```http
POST /api/openapi/jobs/{job_id}/approve
Content-Type: application/json
{
"endpoints": [
{
"path": "/orders/{order_id}",
"method": "get",
"access_type": "read",
"agent_group": "order_agent"
}
]
}
```
## Access Type Classification
| Access Type | Description | Interrupt Required |
|-------------|-------------|-------------------|
| `read` | GET operations, no side effects | No |
| `write` | POST/PUT/PATCH that modify data | Yes |
| `admin` | DELETE, bulk operations, sensitive writes | Yes |
## SSRF Protection
All import requests are validated against an allowlist:
- Private IP ranges are blocked (10.x, 172.16.x, 192.168.x, 127.x)
- Localhost and metadata service URLs are blocked
- Only `http://` and `https://` schemes are permitted
To allow internal URLs (e.g., in development), set `SSRF_ALLOWLIST_HOSTS` in your environment.
## Supported Spec Formats
- OpenAPI 3.0.x (JSON or YAML)
- Swagger 2.0 is not supported
## Limitations
- Maximum spec file size: 1 MB
- Maximum endpoints per spec: 200
- Specs requiring authentication headers are not yet supported for import

- `README.md` -- Complete rewrite in English
- `backend/.env.example` -- Added all new variables
## Test Coverage
- Unit tests added: 42 (13 conversation_tracker + 19 error_handler + 10 edge_cases)
- Integration tests updated: 1
- Unit tests updated: 4 (version + content limit alignment)
- Total tests: 449 passing
- Overall coverage: 92.88%
## Deviations from Plan
- `MAX_CONTENT_LENGTH` changed from 8000 to 10000 to match plan spec (>10000 = too long).
Updated all tests that referenced the old 8000/9000 boundary.
- `_thread_timestamps` is module-level; added autouse pytest fixture to clear it between
tests to prevent state leakage.
- `FireAndForget` tracking uses direct `await` (not background tasks) since the
WebSocket loop is already async and fire-and-forget with proper exception suppression
is sufficient.
## Known Issues / Tech Debt
- `app/main.py` coverage is 48% -- the lifespan/startup path is not covered by unit
tests (requires a real DB). This is expected and the overall 93% coverage more than
meets the 80% threshold.
- Rate limit state (`_thread_timestamps`) is process-global and will not work correctly
with multiple workers. For multi-worker deployments, use Redis-backed rate limiting.
- The `conversations` table schema is assumed to exist; `setup_app_tables` should be
extended to create it if not present (deferred to a future patch).
