README (SKILL.md)
eBay Price Check Skill
Check eBay item prices, including sold listings for historical data.
Usage
Check current price of an item
/eBay price check iPhone 14 Pro Max 256GB
Check sold prices (historical data)
/eBay sold prices MacBook Pro 14" M3
Get price history summary
/eBay price history Samsung Galaxy S23
Capabilities
- Search eBay for items by keyword
- Get current listing prices (active listings)
- Get sold prices (historical data from sold listings)
- Price range analysis (min/max/average)
- Shipping cost information
- Item condition filtering (new, used, refurbished)
How it Works
- Searches eBay using their public search API
- Parses results to extract prices, titles, shipping costs
- For sold prices, filters by "Sold Items" category
- Returns formatted summary with price statistics
Notes
- Requires internet connection
- eBay may limit search frequency
- Sold data may not be available for all items
- Prices shown are in USD unless specified
Usage Guidance
This skill is not overtly malicious, but it is inconsistent and buggy. SKILL.md claims use of eBay's public API but the code actually scrapes eBay HTML via curl — that may violate eBay's terms and will be more fragile. The Python script contains an obvious bug (calling .decode on a string), and the shell wrapper constructs an incorrect path (it references scripts/scripts/...), so the shipped code likely fails as-is. The price-extraction uses a very permissive regex and can return many non-price numbers, producing incorrect statistics. Before installing or running: (1) review and edit the code to correct path/decoding bugs; (2) consider using eBay's official API (with proper credentials) instead of scraping; (3) test the scripts in an isolated environment since they make outbound HTTP requests; (4) ask the author to fix SKILL.md to accurately describe scraping vs API usage. If you need guaranteed, accurate results or compliance with eBay policies, do not use this skill until it is corrected.
Capability Analysis
Type: OpenClaw Skill
Name: ebay-price-check
Version: 1.0.0
The skill is a straightforward tool for checking eBay prices by fetching public search results via curl and parsing them with Python. It uses proper URL encoding for user queries and lacks any indicators of data exfiltration, persistence, or malicious execution. A minor path error exists in the shell wrapper (scripts/ebay-price-check.sh), but the code logic is transparent and aligns with its stated purpose.
Capability Assessment
Purpose & Capability
The stated purpose (search eBay, current and sold prices, price stats) aligns with the included scripts which fetch eBay search pages and extract prices. However, SKILL.md explicitly says it uses eBay's public search API while the code performs HTML scraping of eBay pages via curl — this is an incoherence between claimed capability and implementation. package.json also lists a nonstandard dependency ('python3') in an npm-style dependencies block, which is misleading.
Instruction Scope
SKILL.md describes behavior at a high level and does not mention running the included local scripts; the included Python script actually runs curl to fetch eBay HTML and parses it locally. The instructions claim an API-based approach but the code scrapes HTML. The scraping logic uses a broad regex that will match many unrelated numbers in page HTML, so results can be noisy or inaccurate. The code does not read extra system files or environment variables beyond making network requests to eBay.
Install Mechanism
No install spec that downloads arbitrary code at runtime; this is an instruction-only skill with bundled scripts. package.json lists chmod steps but there is no automated installer that fetches remote artifacts. Risk from the install mechanism is low.
Credentials
The skill requests no environment variables or credentials — appropriate for a read-only price-checker. Network access is required (noted in SKILL.md) and the script reaches out to eBay directly; no unrelated secrets or services are requested.
Persistence & Privilege
The skill does not request always:true and has no special persistence or cross-skill configuration. It will execute only when invoked (user-invocable).
