Free OpenClaw Skill for Vintage Resale Stores: Multi-Channel and Authentication Agent (Download)

What this skill does for your vintage resale stores

• Maintains the cross-channel listing inventory across eBay, Grailed, Depop, Poshmark, and Buya; pulls a SKU from all channels in under 90 seconds when it sells anywhere.
• Runs the Entrupy authentication queue: which items need authentication, what is the expected authentication-cost vs sale-price margin, when did the lab return the report.
• Owns the consignor payout cadence: per-consignor net-of-fees ledger, monthly statement draft, dispute handling for returned or damaged consigned items.
• Drafts platform-specific listings: eBay long-form with measurements and flaw transparency, Grailed condition-graded copy, Depop younger-buyer voice, Poshmark hashtag pack.
• Routes every customer-facing message that touches authentication disputes, consignor payouts over the threshold, or chargebacks to a human; flips routine listing and shipping replies to autonomous after validation.

# OpenClaw Skill: Vintage Resale Multi-Channel and Authentication Coordinator

## Overview

This skill turns the OpenClaw agent into the multi-channel and authentication
back office for a vintage resale store. It owns cross-listing across eBay,
Grailed, Depop, Poshmark, and Buya, the Entrupy authentication queue for
luxury items, the consignor payout cadence, and the channel-specific listing
voice.

The two big back-office failures in resale are the duplicate-sold scramble
when the same item sells on two channels at once, and the consignor payout
drift that happens when the bookkeeping is in a spreadsheet that nobody owns.
This skill keeps both clean.

Designed for single-location and small-chain vintage resale stores running
ConsignCloud or RICS, with active listings across at least two of eBay,
Grailed, Depop, Poshmark, and Buya.

## What this skill does

1. Cross-channel inventory sync: pull a SKU from all channels in 60 to 90 seconds when it sells anywhere
2. Channel-specific listing draft: eBay long-form, Grailed graded, Depop short, Poshmark hashtags
3. Entrupy authentication queue management for luxury inbound
4. Consignor payout ledger: per-consignor net-of-fees statement, monthly cadence
5. Dispute and damaged-item handling routed to the owner
6. Cross-channel customer memory for repeat buyer recognition

## Triggers

```yaml
triggers:
  - type: heartbeat
    schedule: "0 18 * * 0"          # Sundays 6pm
    action: weekly_cross_channel_sync_and_listing_queue

  - type: heartbeat
    schedule: "0 8 15 * *"          # 15th of each month
    action: draft_consignor_payout_statements

  - type: heartbeat
    schedule: "0/5 * * * *"         # Every 5 minutes during open hours
    action: poll_channels_for_new_sales

  - type: on_event
    event: channel.sold_event
    action: pull_listings_from_other_channels

  - type: on_event
    event: pos.luxury_item_intake
    action: route_to_entrupy_queue

  - type: on_event
    event: entrupy.report_received
    action: log_authentication_result_and_update_listing
```

## Workflow: cross-channel inventory sync

When any channel fires a sold event:

1. Match the sold SKU to the cross-channel listing map
2. Issue end-listing or quantity-decrement API calls to the other channels within 60 to 90 seconds
3. Verify each pull-down succeeded; log any failure for retry
4. If a duplicate-sold race condition is detected (two channels sold within the polling window), flag for owner decision
5. Update the consignment software (ConsignCloud / RICS) inventory status

The duplicate-sold race is unavoidable on hot inventory. The skill catches the
common case where one channel sells and the others have 60 to 90 seconds of
exposure, but a true simultaneous sale across two channels still requires
owner intervention. The owner picks which buyer gets the item; the skill
drafts the cancellation message to the other buyer with a discount-on-
substitute offer.

## Workflow: channel-specific listing draft

When new inventory enters the system (intake record with photos, measurements,
condition notes), the skill drafts platform-specific listings:

```yaml
listing_styles:
  ebay:
    voice: long_form_descriptive
    requires: [full_measurements, flaw_disclosure, provenance, return_policy]
    keywords: [brand, era, style, fabric_content, condition_grade]

  grailed:
    voice: menswear_graded
    requires: [pit_to_pit, length, sleeve, shoulder, condition_grade, designer_archive_reference]

  depop:
    voice: short_form_trend
    requires: [vibe_descriptor, trend_hashtag_pack, styling_suggestion]

  poshmark:
    voice: hashtag_heavy_styling_tip
    requires: [styling_tip, hashtag_pack_of_20_to_30, brand_listing]

  buya:
    voice: jewelry_luxury_clinical
    requires: [metal_content, stone_specs, hallmark_documentation, certified_appraisal_link_if_applicable]
```

The same intake record produces 5 channel-specific drafts. The owner reviews
once. The skill posts when approved.

## Workflow: Entrupy authentication queue

For luxury intake (LV, Goyard, Hermes, Chanel, Dior, Gucci, Prada, Fendi,
Balenciaga, Saint Laurent, designer streetwear), the skill:

1. Routes to the Entrupy queue with the item details and photos
2. Computes the authentication-cost vs expected-sale-price margin
3. Surfaces items where authentication is not economic (low expected sale price)
4. Logs the Entrupy report when it returns
5. Embeds the Entrupy certificate of authenticity into the channel listings

Default rule: authenticate any LV, Hermes, Chanel, or Dior over $300 expected
sale price. Authenticate any other designer over $500. Below those thresholds,
sell with photo-based authentication notes and accept the buyer-side risk
that some channels (Poshmark, Depop) will not authenticate themselves.

## Workflow: consignor payout cadence

On the 15th of each month, the skill:

1. Pulls every sold item from the prior month tagged to a consignor
2. Computes the gross sale, platform fee, in-house commission split, net payable
3. Drafts the consignor statement with line-item detail
4. Surfaces consignors above the configured threshold (default $500) for owner sign-off
5. Routes statements below the threshold to autonomous send (after validation period)

The consignor statement is the most under-managed bookkeeping output in resale.
Consignors who do not get a clean monthly statement stop bringing inventory.

Write-back to ConsignCloud and RICS starts disabled. The skill drafts inventory
status updates; the owner commits.

## Compliance notes

Cross-channel selling triggers each platform's policy enforcement. eBay and
Grailed both have anti-cross-listing detection that can flag accounts for
duplicate listings. The skill's pull-down speed (60 to 90 seconds typically)
keeps duplicate-listing exposure short, but the owner remains responsible for
each channel's policy compliance.

Consignor payouts are typically taxable income to the consignor. The skill
maintains 1099-relevant gross totals per consignor for end-of-year reporting.
It does not file 1099-K or 1099-MISC; the owner's accountant does.

## Configuration

```yaml
config:
  shop_name: "Your Resale Shop"
  consignment_software: consigncloud  # or "rics", "simpleconsign", "liberty"
  channels_active: [ebay, grailed, depop, poshmark, buya]
  consignor_split_default: 0.55     # consignor gets 55%, shop gets 45%
  payout_day_of_month: 15
  payout_threshold_owner_review_usd: 500
  entrupy_threshold_top_luxury_usd: 300
  entrupy_threshold_other_designer_usd: 500
  channel_polling_interval_minutes: 5
  approval_mode: owner_approves_all   # or "autonomous_after_2_weeks"

Install in 60 seconds

1. 1

   Drop the file into your OpenClaw skills directory

   Save the downloaded vintage-resale-stores.md as ~/.claude/skills/vintage-resale-coordinator.md (or your project-level .claude/skills/ if you run multiple storefronts). OpenClaw picks up new skill files on next agent launch.

2. 2

   Connect your consignment software and channel APIs

   Edit the integrations block to point at your ConsignCloud or RICS export, plus your eBay developer API, Grailed seller token, Depop API access, Poshmark Posh Stories API or browser-extension bridge, and Buya merchant key. Add your Entrupy API key if you authenticate inbound luxury items. Read-only is enough to start.

3. 3

   Launch in owner-approval mode, validate, then go autonomous on routine traffic

   Start with the owner approving every cross-listing and every consignor payout statement for two weeks. The skill defaults route authentication disputes, consignor payouts over $500, and any chargeback to a human. After two weeks, flip routine listing drafts and shipping replies to autonomous.
