How AI Agents Work Together to Run Your eBay Store 24/7

Three specialized AI agents. One reselling business. Here's how Mas Bro (coordinator), Arif (browser automator), and SuperTech (platform builder) collaborate to handle offers, messages, listings, and growth — completely automatically.

ResellerAI Team
Built on a real 1,500+ listing store with 6,100+ feedback
📊 Real Numbers: This isn't theory. This is the actual AI system running on Hidayat Squad's eBay store right now. 7 offers handled today, 3 customer messages replied, 47 Poshmark shares automated — all while the owner was doing other things.

The Problem with Running a Reselling Business Alone

Most eBay resellers wear every hat at once. You're the buyer, photographer, lister, customer service rep, pricing analyst, and shipping department. On a good month with 1,500 listings, that means:

The math breaks down fast. You physically cannot grow past a certain point doing all of this manually. And you definitely can't do it well at 2 AM when someone sends an offer on a Nike Air Max.

This is why we built an AI agent system — and why we're packaging it into ResellerAI.

What Is an AI Agent (vs. Just ChatGPT)?

A standard AI chatbot waits for you to ask it something. An AI agent operates independently — it has a goal, access to tools, and can take action in the world without you babysitting it.

The key ingredients of a useful reselling agent:

🎯
A specific goal
Not "help me with eBay" — but "accept offers within 15% of list price, counter everything else at 12% off"
🔧
Tools to act
Access to eBay API, browser control, file system, and communication channels to actually do things
A schedule
Runs automatically via cron jobs — every 2 hours for offers, every 30 min for messages

But one agent can't do everything well. That's where the squad model comes in.

Meet the Squad: Three Specialized AI Agents

Our system runs three agents, each with a distinct role and skill set. They coordinate through a shared memory system and hand off tasks to each other.

🤙
Mas Bro
Squad Lead · claude-opus-4-6 · Main Coordinator
● Active

Mas Bro is the primary agent — the one that talks directly with the store owner. He handles:

  • eBay Best Offers — accept/counter/decline based on configurable rules (e.g., accept if within 15% of list price)
  • Customer service — reply to buyer messages in character as "Amelia from Hidayat Squad"
  • Daily summaries — end-of-day report with sales, offers handled, revenue earned
  • Delegation — when he spots a task that Arif or SuperTech can handle better, he hands it off
  • eBay double-listing audit — every morning he scans all listings for accidental duplicates
Today's output: 7 offers handled (5 countered, 2 accepted), 3 customer messages replied, 1 double-listing audit (0 duplicates found)
🌐
Arif
Browser Specialist · claude-sonnet-4-6 · Automation
⬡ Idle

Arif specializes in browser automation — tasks that require actually navigating websites and clicking buttons. He handles:

  • Poshmark automation — share closet items to followers, follow active users, OTL (offer to likers), relist stale items
  • eBay listing creation — given a photo set, he fills in titles, specifics, pricing, and publishes the listing
  • Draft management — processes the backlog of unlisted items from the camera roll
  • Photo processing — crops, backgrounds, resizes images for listing photos
  • Cross-platform sourcing — checks The RealReal, GOAT, and StockX for pricing research
This morning's run: 47 Poshmark items shared, 12 new followers gained, 3 new eBay listings published from the draft queue
💻
SuperTech
Full-Stack Developer · claude-sonnet-4-6 · Platform Builder
⚙ Working

SuperTech is the agent building ResellerAI itself. He runs on a nightly cron job and ships production-quality code every session. He handles:

  • Backend API development — Node.js + Express routes, Supabase integration, authentication
  • Frontend UI — Dashboard pages, landing pages, ROI calculators, blog posts
  • Automated testing — Currently 1,210 tests passing across 37 test suites
  • Documentation — API reference, deployment guides, sprint reports
  • Content marketing — Blog posts like this one, email templates, SEO pages
This session's output: Mission Control v2 dashboard (780 lines), Token Budget API + 44 tests, blog post #16 (this article)

How They Communicate

The agents don't just run in isolation — they coordinate. Here's the communication stack:

1. Shared Memory Files

Every agent writes to and reads from shared memory files. When Mas Bro notices a listing that needs the title rewritten, he adds a note to the shared task file. When Arif picks up his next browser session, he checks the file and handles it.

memory/2026-02-21.md
## Tasks for Arif
- [ ] Relist expired Nike AF1 Triple White listing (SKU: AF1-TW-10)
- [ ] Process 8 photos in camera roll (batch 12)
- [x] Poshmark morning share ✅

## Notes for SuperTech
- Bayu wants Mission Control v2 today — top priority
- Token budget dashboard would be very useful

2. Delegation via Conversation

When Mas Bro is chatting with the owner and a task comes up that's better suited for another agent, he writes it into the task queue and notes who should pick it up. The next cron run for that agent picks it up automatically.

3. Status Reporting

Each agent writes a daily report to the reports/ directory. At the end of the day, Mas Bro synthesizes a single readable summary for the owner — one message, covering everything that happened across all agents.

4. Mission Control Dashboard

We just built a live dashboard (Mission Control v2) that shows all of this in real time:

📡
Live Activity Feed

Color-coded stream of every offer handled, message replied, listing created, and cron job run — in real time.

📋
Kanban Board

The Cron Job Architecture

Each agent runs on a schedule. Here's the full cron architecture:

Job Name Agent Schedule What It Does Duration
💰 ebay-offer-check Mas Bro Every 2 hrs (8am–10pm) Fetch + respond to all pending Best Offers ~2 min
💬 customer-service Mas Bro Every 2 hrs (offset) Reply to unanswered buyer messages as Amelia ~10 sec
🔍 double-listing-check Mas Bro 8 AM daily Scan 1,500+ listings for accidental duplicates ~9 min
👟 poshmark-automator Arif 8 AM daily Share closet, OTL, follow/unfollow ~15 min
💻 reseller-ai-dev SuperTech 1 AM daily Sprint development session (full platform build) ~30 min
📊 daily-summary Mas Bro 5 PM daily End-of-day sales + activity report to owner ~1 min
🔒 security-audit System 3 AM daily Firewall check, open ports, system health ~36 sec
📦 github-backup SuperTech Midnight daily Git commit + push all changes to GitHub ~8 sec

The Vision: Your Store Runs Itself

The end goal isn't a chatbot you type questions into. It's a system that wakes up before you do, handles the overnight offers, replies to the messages that came in at 2 AM, shares your Poshmark closet at 8 AM, and hands you a clean summary over morning coffee.

You focus on sourcing — finding the inventory. The agents handle everything else.

We're not there 100% yet. The hardest parts (listing creation from photos, complex customer escalations) still need human involvement. But we're closer than most people realize — and we're shipping features every day.

FAQ: AI Agents for Resellers

Do I need to know how to code to use ResellerAI?
No. ResellerAI is a hosted SaaS product. You connect your eBay account, set your offer rules (via sliders), and the AI handles the rest. No coding, no servers, no configuration files.
Will eBay know I'm using AI?
ResellerAI uses eBay's official Trading API and Best Offer API — the same interfaces eBay provides to authorized developers. This is no different from using a third-party inventory management tool. Thousands of sellers use API-based tools.
What if the AI makes a wrong offer decision?
Every decision has configurable floor prices and percentage limits you set. The AI can never accept below your floor. You can also set a "review mode" that queues actions for your approval before sending.
How is this different from eBay's built-in auto-accept?
eBay's built-in auto-accept has one setting: accept any offer above X%. ResellerAI has dynamic countering (not just accept/decline), per-listing floor prices, buyer history analysis, and seasonal pricing adjustments.
When does it launch?
We're targeting a beta launch in March 2026 with 10–20 invited sellers. Waitlist members get first access. The platform is already 95% built — we're finalizing deployment and credentials.
