# Phase 2: Multi-Agent Routing + Safety -- Development Log
|
||
|
||
> Status: COMPLETED
|
||
> Phase branch: `phase-2/multi-agent-safety`
|
||
> Date started: 2026-03-30
|
||
> Date completed: 2026-03-30
|

|
||
## What Was Built
|
||
|
||
- **Intent Classification** (`app/intent.py`): LLM 结构化输出意图分类器，Pydantic 模型（IntentTarget, ClassificationResult）。支持单意图、多意图、模糊检测，可配置置信度阈值。
|
||
- **Discount Agent** (`app/agents/discount.py`): Mock Agent，apply_discount（write + interrupt）和 generate_coupon（read）。验证折扣范围 1-100%。
|
||
- **Interrupt Manager** (`app/interrupt_manager.py`): TTL 中断追踪，30 分钟自动过期。提供 register, check_status, resolve, cleanup_expired, generate_retry_prompt。
|
||
- **Webhook Escalation** (`app/escalation.py`): HTTP POST 升级，指数退避重试（最多 3 次）。WebhookEscalator + NoOpEscalator，EscalationService Protocol。
|
||
- **Enhanced Supervisor** (`app/graph.py`): 动态 Agent 描述 Supervisor 提示。意图分类器附加到 graph。多意图提示注入。
|
||
- **Vertical Templates**: 三个行业 YAML 模板（电商、SaaS、金融科技）。
|
||
- **Template Loading** (`app/registry.py`): load_template() 和 list_templates()。
|
||
- **WebSocket Integration**: 模糊意图发送澄清消息。中断 TTL 检查 -- 过期中断返回重试提示。
|
||
|
||
## Test Coverage
|
||
|
||
- Total: 153 tests (Phase 1: 87 + Phase 2: 66)
|
||
- Coverage: 90.18%
|
||
- intent.py: 100% | discount.py: 96% | interrupt_manager.py: 100% | escalation.py: 100%
