Walmart Product Detail

Walmart — Product Detail

> product URL → full structured product data from walmart.com product detail page

Language

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

Objective

Extract complete product data from a Walmart product detail page, including pricing, images, specifications, variants, fulfillment options, and review summary.

Prerequisites

• Target product page is open in the browser: https://www.walmart.com/ip/{product-slug}/{item-id}

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, never bypassing authentication or access controls. Its role is equivalent to copy-pasting on the user's behalf — the data is already on screen, automation merely saves time. JS code is encapsulated in Python files under the scripts/ directory, invoked via eval "$(python scripts/xxx.py {params})". $(...) is bash syntax; it is recommended to use the bash tool for execution.

Below are all atomic capabilities discovered and verified during the exploration phase, listed by command template with parameters. Simply invoke them as needed — no need to read scripts/*.py source code or re-verify. Only inspect scripts when execution fails for troubleshooting. Combine freely as needed during execution.

DOM: extract full product data from current product page

Navigate to the product URL first, then extract:

• navigate "https://www.walmart.com/ip/{product-slug}/{item-id}"
• wait stable
• eval "$(python scripts/extract-product-detail.py)"

The item-id is the numeric Walmart item ID (usItemId). The product-slug portion of the URL does not affect which product is loaded — only the item-id matters.

Output example:

Error response (when extraction fails or wrong page):

Success Criteria

itemId is non-null AND title is non-null AND price is non-null OR availability is non-null

Known Limitations

• wasPrice is null unless the item currently has an active markdown/rollback promotion
• sellerAverageRating and sellerReviewCount are null for Walmart first-party listings (INTERNAL sellerType)
• longDescription may be null for items without IDML data (less common)
• specifications may be empty for items without IDML specifications
• Variant itemIds are internal product IDs (format: alphanumeric, e.g., "6G9VW0QQAI2X"), not the usItemId; to get the usItemId for a specific variant, navigate to that variant's URL
• Delivery dates in fulfillmentOptions reflect the browser session's location context (set by the browser's stored zip code)

Execution Efficiency

• Batch orchestration: Write a bash script to loop through product URLs serially within a single session; do not parallelize within one browser (prone to triggering anti-scraping restrictions). Add 1–2 second intervals between navigations. To increase throughput, open multiple stealth browser sessions and distribute work across them — each session has an independent fingerprint so rate limits apply per session
• Test before batch execution: After writing a batch script, you must first test with 1-2 items to verify the script runs correctly; only then run the full batch. Never skip testing and execute in batch directly
• Reduce redundant pre-operations: When multiple steps depend on the same prerequisite state, complete them in batch under that state to avoid repeatedly establishing the same state
• Error resumption: Save results item by item during batch processing; on failure, resume from the breakpoint rather than starting over

Experience Notes

Path: {working-directory}/browser-act-skill-forge-memories/walmart-scraper-walmart-product-detail.memory.md (working directory is determined by the Agent running the Skill, typically the project root or current working directory)

Before execution: If the file exists, read it first — it records unexpected situations encountered during past executions (e.g., a strategy has become ineffective); 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}

Normal execution does not write to the file. Do not record what product URLs were scraped or what prices were found — those are task outputs, not experience.
