broker-card: Generate, Review, and Publish Listings
Generates platform-specific listing cards, collects schedule+fuse settings, and auto-publishes on user confirmation.
Workflow
Phase 1: Card Generation
For each target platform, generate a formatted listing card:
┌─────────────────────────────────────┐
│ 🛍️ 闲鱼 Xianyu 上架卡片 │
├─────────────────────────────────────┤
│ 📝 标题: [platform-optimized] │
│ 📂 分类: [platform category path] │
│ 💰 价格: ¥XXX │
│ 📋 描述: [platform-tone adapted] │
│ 🏷️ 标签: #tag1 #tag2 #tag3 │
│ ⚠️ 成色: Grade X — [detail] │
└─────────────────────────────────────┘
Phase 2: Schedule + Shield (MANDATORY before publishing)
- Price shield: Unbreachable floor price. This MUST be set via
broker-fuse before publishing. The publish script validates: if no floor is set, publishing is blocked.
- Repricing interval: How often to re-check prices (default 7 days)
Explain the trade-off: higher floor = more profit per sale but slower; lower floor = faster liquidity.
Phase 3: Publish (floor-gated)
- Floor validation: script checks
listing.fuse_price > 0 and listing.current_price >= listing.fuse_price. Blocked otherwise.
- User says "发布" or "confirm"
- Script auto-publishes to each platform using stored session
- Each publish event is logged to the audit trail (
audit_logger.log_publish)
- Each listing URL is saved to state manager
- System scheduler is registered for repricing checks
