What it does

Ecommerce Seller Info is an agent skill from browser-act/skills. Extract seller or merchant profile data from marketplace platform seller pages. Returns seller name, rating, review count, positive feedback percentage, joined date, and return policy. Works on Amazon seller pages, eBay seller pages, and any e-commerce site with seller profiles. Use when: seller information, merchant profile, seller rating, marketplace seller data, seller details, vendor profile, store information, seller feedback, merchant rating, seller review count, get seller info, ebay seller page, amazon…

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/extract-seller.py`).

It sits in Sales & Support, covering E-commerce operations. It works with Python. The repository describes itself as: Browser automation CLI built for AI agents. Break through anti-bot walls, hand off to humans across platforms when stuck. Parallel multi-task execution, independent multi-session… The licence is MIT.

When your agent uses it

  • : seller information
  • Merchant profile
  • Marketplace seller data
  • Store information

Example prompts

  • “/ecommerce-seller-info”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

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

What it can do on your machine

Read from SKILL.md and the folder at commit 11c057b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • amazon.com
    • ebay.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ecommerce Seller Info loads about 1.2k tokens when it runs. Until then it costs about 150 tokens; SKILL.md has 448 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~150
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Use when: seller information, merchant profile, seller rating, marketplace seller data, seller details, vendor profile, store information, seller feedback, merchant rating, seller review count, get seller info, ebay seller page, amazon seller profile, marketplace vendor analysis, seller research.

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:

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

Output example:

json
{
  "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 typeURL
Seller storefronthttps://www.amazon.com/shops/{seller_id}
Seller feedback (from product page)Click "Sold by {seller_name}" link on a product page
Third-party seller ratingshttps://www.amazon.com/gp/seller/{seller_id}/ref=dp_byline_sr

To find a seller from a product page:

  1. Navigate to product page → wait stable
  2. eval "document.querySelector('#sellerProfileTriggerId, #merchant-info a')?.href" to get the seller URL
  3. navigate {seller_url} → wait stable
  4. eval "$(python scripts/extract-seller.py)"
Composite: eBay seller URL patterns
Seller page typeURL
eBay seller storefronthttps://www.ebay.com/str/{seller_username}
eBay seller feedbackhttps://www.ebay.com/usr/{seller_username}

To find seller from an eBay listing:

  1. Navigate to eBay item page → wait stable
  2. eval "document.querySelector('.x-sellercard-atf__data a[href*=\"/usr/\"]')?.href" to get seller URL
  3. 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}
