Description
Smart shopping assistant for Mainland China that searches JD/Taobao, compares prices, confirms needs, calculates final cost, and generates purchase links.
Usage Guidance
This skill appears to be a legitimate shopping assistant, but it sends all searches and user intent to a third-party MCP server at an IP address (81.70.235.20) and returns affiliate links while explicitly hiding commission info. Before installing or using it: 1) Do not send personal or sensitive data (addresses, payment info, identity details) through the skill. 2) Ask the publisher for a verifiable domain, privacy policy, and disclosure of affiliate/commission arrangements; lack of a homepage/owner identity is a red flag. 3) Prefer skills hosted on known domains or provided by trusted publishers. 4) If you must test it, do so with generic, non-identifying queries and monitor outbound network destinations/logs. If transparency or privacy guarantees are required, treat this skill as untrusted until the endpoint and monetization are verified.
Capability Analysis
Type: OpenClaw Skill
Name: saver-skill
Version: 1.1.1
The 'saver-skill' is a shopping assistant for Chinese e-commerce platforms (JD/Taobao) that connects to an external MCP server at http://81.70.235.20:3001/mcp. The skill's documentation (SKILL.md) and configuration (config.json) clearly outline its purpose, including the generation of affiliate links for monetization. No evidence of data exfiltration, unauthorized command execution, or malicious prompt injection was found; the instructions provided to the AI agent are consistent with the stated shopping assistant functionality.
Capability Assessment
Purpose & Capability
The name/description (shopping assistant for JD/Taobao in China) matches the declared tools and the config.json (unified_search, analyze_shopping_need, etc.). Generating affiliate links and price calculations is coherent with the stated purpose. However, the service endpoint is a bare IP (http://81.70.235.20:3001/mcp) with no homepage or publisher identity, and the SKILL.md explicitly states 'commission info is NOT exposed to users' — a monetization/conflict-of-interest disclosure gap that users should be aware of.
Instruction Scope
The runtime instructions require the agent to send user queries and shopping intents to the remote MCP server (streaming/SSE). While required for a remote search service, this means potentially sensitive user info (product preferences, intended purchases, possibly context carried by the agent) will be transmitted off-platform to an unverified third party. The instructions also direct conversion to affiliate links and explicitly hide commission info from users, which is a policy/transparency concern.
Install Mechanism
No install spec or code files — lowest local install risk. However, the skill relies entirely on network calls to a third-party MCP server identified by a raw IP address rather than a well-known domain or official release host, which increases operational risk (unverifiable endpoint, harder to audit or attribute).
Credentials
The skill declares no required environment variables, credentials, or config paths, which is proportionate. That said, because it forwards queries to an external service, privacy-sensitive data could be transmitted at runtime even without declared credentials — the lack of required credentials doesn't eliminate data-exfiltration risk via network calls.
Persistence & Privilege
The skill is not marked 'always: true', it is user-invocable, and there is no indication it modifies other skills or system-wide settings. It does not request persistent privileges in the manifest.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install saver-skill - After installation, invoke the skill by name or use
/saver-skill - Provide required inputs per the skill's parameter spec and get structured output
