## Capabilities

- Runs a bundled Python script that starts a BrowserAct workflow for one ASIN.
- Accepts an Amazon marketplace URL to target a regional marketplace.
- Polls BrowserAct task status until completion or a five minute timeout.
- Returns product title, Buy Box owner, price, currency, and availability when provided by the API.
- Includes other seller pricing, shipping fee, rating, and feedback data when available.
- Detects missing or invalid BrowserAct API key errors and reports them to the user.

## Use Cases

- Check Buy Box Ownership: Find the current Buy Box owner, price, availability, and fulfillment method for a specific ASIN.
- Compare Competitor Sellers: Review other seller prices, shipping fees, ratings, and feedback counts for a product listing.
- Validate Regional Listings: Run the same ASIN against a selected Amazon marketplace URL to inspect regional listing details.

## Prompt Templates

### Check One ASIN

```
Use the Amazon Buy Box monitor for ASIN B005O2ZU68 on https://amazon.com/ and summarize the current Buy Box result.
```

### Compare Other Sellers

```
Run the Amazon Buy Box monitor for this ASIN and list other sellers by total price, rating, and fulfillment method.
```

### Review Regional Marketplace

```
Check ASIN B005O2ZU68 on https://amazon.co.uk/ and report the Buy Box owner, currency, availability, and seller details.
```

### Diagnose Failed Run

```
Run the monitor for this ASIN. If it fails, inspect the terminal output, retry once when appropriate, and explain the final error.
```

## Limitations

- Requires a valid BROWSERACT\_API\_KEY before it can run.
- Depends on BrowserAct and Amazon page availability, so results may fail or change.
- Processes one ASIN per script invocation.
- Does not store history or create long-term price trend reports by itself.

## Best Practices

- Set BROWSERACT\_API\_KEY as an environment variable instead of pasting it into chat.
- Use a complete Amazon marketplace URL that matches the region you want to inspect.
- Verify important price decisions against Amazon directly before making business changes.

## Anti Patterns

- Do not use the skill for bulk scraping without confirming BrowserAct and Amazon policy requirements.
- Do not paste private API keys into prompts, tickets, or shared transcripts.
- Do not treat one lookup as a historical trend or long-term monitoring record.

## Security Audit

- - Safe to publish: true
- - Audited at: 2026-06-28T17:26:29.012\+00:00
- - Summary: Static analysis found network access, environment variable access, shell invocation guidance, and a critical combined-behavior heuristic. Review confirmed these patterns support the documented BrowserAct API workflow, with no prompt injection or confirmed malicious exfiltration found. The remaining risk is medium because the skill handles an API key and sends ASIN and marketplace data to a third-party service.
