Goofish (闲鱼) — Item Detail

item URL (or item_id + category_id) → full listing data: title, price, seller info, description, images, tags, want-count

Language

Objective

Prerequisites

• Browser with an active Goofish session (login required — item detail pages require authenticated access)
• Target item URL format: https://www.goofish.com/item?id={item_id}&categoryId={category_id}

Pre-execution Checks

1. Tool Readiness

2. Login Verification

• User avatar or account entry exists → logged in, continue
• Login/register prompt → not logged in; inform user that login is required; assist login flow

Capability Components

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

Network Capture: load item detail page

1. navigate https://www.goofish.com/item?id={item_id}&categoryId={category_id}
2. wait stable
3. Proceed to DOM extraction below

• If a CAPTCHA slider appears ("Please slide to verify"): the session is rate-limited. Wait 5–10 minutes, or use remote-assist to complete the slider manually, then re-navigate.
• If "网络不见了" error page appears: the item page API call failed. Retry once after 30 seconds; if it persists, the session may be temporarily blocked.
• If item shows "该宝贝已下架" or similar: item has been removed/sold — skip and move to next item.

DOM: extract item detail data

Success Criteria

Known Limitations

• Seller user ID (numeric) is not exposed in the DOM — only seller display name is available
• Item detail pages trigger CAPTCHA if accessed too rapidly; recommended minimum interval: 3 seconds between items
• Some items may require login even for viewing; the Skill will return an error if the page fails to load
• Rapid successive navigation may trigger "网络不见了" error — wait 30 seconds before retrying

Execution Efficiency

• Batch orchestration: Loop through item IDs serially with 3–5 second delays; do not parallelize within one browser. To increase throughput, distribute items across multiple browser sessions
• Test before batch execution: Test with 2–3 items first to confirm selectors are valid; only then run the full batch
• Error resumption: Save results item-by-item; on failure (CAPTCHA or error), record the failed item ID and resume after the CAPTCHA clears
• Get item IDs from search: Use goofish-search-list Skill to collect item IDs, then feed them into this Skill for detail enrichment
