Smart Resale Agent — Hub

Orchestrates the complete C2C resale workflow: photo recognition → price research → platform auth → listing card & publish → schedule + fuse → auto-delist on sale.

Two Modes

Mode A: MCP Server (v2, recommended for non-Claude-Code clients)

Use broker_core/mcp_server.py — a standard MCP server exposing 7 tools. Any MCP-compatible client (Claude Desktop, Cursor, VS Code) can connect.

Mode B: Claude Code Skills (v1, still supported)

Use the 7 /broker-* slash commands within Claude Code CLI.

For MCP Mode

Load guardrails/Omni-Agent-Guardrails.yaml as the system prompt. This enforces:

• Tool Routing: Step 1→2→3→4→5 forced order
• Shield Protocol: blocked=true → all actions cancelled
• Transparency Schema: Every output carries audit:// reference

MCP tool mapping:

cognitive_intake       → broker-recognize
generate_xai_pricing   → broker-price
fuse_gatekeeper         → broker-fuse (MANDATORY GATE)
execute_platform_action → broker-card + broker-delist
audit_trail_query       → audit_logger
schedule_repricing      → broker-schedule
platform_auth_trigger   → broker-auth

Prerequisites

ANTHROPIC_API_KEY must be set. broker-recognize (Step 1) requires Claude Vision API to analyze product photos. Without this key, photo recognition will fail.

export ANTHROPIC_API_KEY="sk-ant-..."

7-Skill Pipeline

📷 broker-recognize  →  Photo → structured product info
🔐 broker-auth       →  Bind platform accounts (login once, session persisted)
🔍 broker-price      →  Authenticated price search across platforms
🛡️ broker-fuse       →  ⚠️ GLOBAL INTERCEPTOR — set fuse BEFORE publish/schedule
📋 broker-card       →  Listing card preview → user confirmation → auto-publish
⏰ broker-schedule   →  Set repricing interval → register cron/launchd
✅ broker-delist     →  Auto-detect sale → delist all platforms

broker-fuse is NOT step 6. It is a mandatory interceptor/gate. Before broker-card can publish and before broker-schedule can auto-reprice, broker-fuse MUST be called and set. Every publish and repricing action validates against the fuse.

Orchestration Rules

When user wants to sell (full flow)

Guide the user through skills in this order: recognize → auth → price → fuse → card → schedule. Fuse is set as a gate BEFORE card publishing. Schedule is configured during the card conversation before publishing.

Flow control

1. Call broker-recognize — user uploads photo, AI extracts product info. User confirms.
2. Call broker-auth — open browser for each platform user wants to list on. Sessions persist automatically.
3. Call broker-price — search all bound platforms using stored sessions. Present transparency report. User confirms recommended price.
4. MANDATORY GATE: Call broker-fuse — set unbreachable floor price. This is NOT optional. No publishing or repricing may proceed without a fuse set.
5. Call broker-card — generate listing cards. Script validates fuse before publish. Ask user to set repricing interval (default 7 days). User reviews card → says "发布" → script checks fuse → auto-publishes.
6. broker-schedule registers the cron/launchd task. Daily repricing also validates against fuse. Done automatically after publish.
7. broker-delist triggers when: (a) user says "卖了", or (b) daily scheduler detects item sold on a platform.

Standalone usage

Each sub-skill can be invoked independently:

• /broker-recognize — just analyze a product photo
• /broker-price — just research prices for a described item
• /broker-fuse — adjust an existing fuse
• /broker-delist — manually trigger delisting
• /broker-schedule — change repricing interval

Cross-skill data passing

Skills communicate via ~/.broker/listings.json (state_manager) and conversation context. The item_id links everything.
