E-commerce — Seller Info

Seller/merchant profile URL → seller name, rating, review count, feedback, joined date, return policy

Language

All process output to user (progress updates, process notifications) follows the user's language.

Objective

Extract seller profile information from marketplace platform seller or storefront pages using JSON-LD structured data and platform-specific DOM patterns.

Prerequisites

Target browser is open and connected
No login required for public seller profile pages

Pre-execution Checks

1. Tool Readiness

If browser-act has been confirmed available in the current session → skip this step.

Invoke browser-act via Skill tool to load usage. If installation or configuration issues arise, follow its guidance to resolve then retry.

Capability Components

This Skill's operational boundary = what the user can manually do in their browser. It only reads data already displayed to the user on the page. JS code is encapsulated in Python files under the scripts/ directory, invoked via eval "$(python scripts/xxx.py {params})". Use the bash tool for execution.

DOM: Extract seller profile from current seller page

Navigate to the seller profile URL first, then extract:

eval "$(python scripts/extract-seller.py)"

Output example:

{
  "url": "https://www.amazon.com/shops/seller/A1234567890",
  "name": "TechGadgets Store",
  "description": "Premium electronics accessories since 2015",
  "rating": 4.8,
  "review_count": 12450,
  "positive_feedback_pct": "98% positive feedback",
  "joined": "Member since: January 2015",
  "return_policy": "30-day returns accepted",
  "image": null,
  "_platform": "amazon"
}

Composite: Amazon seller URL patterns

Amazon seller pages follow these URL patterns:

Seller page type	URL
Seller storefront	`https://www.amazon.com/shops/{seller_id}`
Seller feedback (from product page)	Click "Sold by {seller_name}" link on a product page
Third-party seller ratings	`https://www.amazon.com/gp/seller/{seller_id}/ref=dp_byline_sr`

To find a seller from a product page:

Navigate to product page → wait stable
eval "document.querySelector('#sellerProfileTriggerId, #merchant-info a')?.href" to get the seller URL
navigate {seller_url} → wait stable
eval "$(python scripts/extract-seller.py)"

Composite: eBay seller URL patterns

Seller page type	URL
eBay seller storefront	`https://www.ebay.com/str/{seller_username}`
eBay seller feedback	`https://www.ebay.com/usr/{seller_username}`

To find seller from an eBay listing:

Navigate to eBay item page → wait stable
eval "document.querySelector('.x-sellercard-atf__data a[href*=\"/usr/\"]')?.href" to get seller URL
Navigate and extract

Success Criteria

result.name != null

Known Limitations

Amazon seller pages may require navigating from https://www.amazon.com first on fresh sessions to avoid bot detection
eBay seller pages may require navigating from https://www.ebay.com first
Seller description and return policy availability depends on whether the seller has filled in their profile
Rating scale differs by platform: Amazon uses 1–5 stars, eBay uses percentage of positive feedback; both are preserved in their native format

Execution Efficiency

Batch orchestration: Loop through seller URLs serially; add 1–2 second intervals between navigations
Test before batch execution: Test with 1–2 sellers before running the full batch
Error resumption: Save results item by item; on failure, resume from the breakpoint

Experience Notes

Path: {working-directory}/browser-act-skill-forge-memories/ecommerce-scraper-ecommerce-seller-info.memory.md

Before execution: If the file exists, read it first — it records unexpected situations encountered during past executions; adjust strategy order accordingly.

After execution: If an unexpected situation is encountered (strategy became ineffective, page redesigned, anti-scraping upgraded, better path discovered), append a line: {YYYY-MM-DD}: {what happened} → {conclusion}
