HK Supermarket Shopping (v1.2.3)
Real-time price lookup for Hong Kong supermarkets using the Consumer Council's daily pricewatch. The price_lookup tool searches for products and returns the cheapest option, price, and how many you can buy with $100. Language (English/Chinese) is auto-detected from your query.
Quick Reference
| Query | Expected Result |
|---|---|
"Coke Zero" |
Overall cheapest: PARKNSHOP - Coca-Cola Zero Sugar 500ml ($9.50). With $100 you can buy 10 items (remaining $5.00). |
"milk" |
Similar format with cheapest supermarket and price |
"雞蛋" |
Response in Chinese: 整體最平：... |
Setup
- Install the skill by copying the folder to OpenClaw's skills/ directory.
- No configuration required.
- The skill downloads the latest pricewatch CSV on first use and stores it in
data/. - Data is automatically housekept; only today's file is kept (older than 1 day removed).
- All downloads use SSL verification; no insecure proxies.
Technical Details
- Data Source: Consumer Council pricewatch (English CSV) – updated daily.
- Retention: 1 day (auto housekeeping).
- Offline Support: Works after initial download.
- Multilingual: Auto-detects query language and responds accordingly.
- Security: Input length limited to 200 characters, SSL-verified downloads, no command injection vulnerabilities, no external binary dependencies.
- Runtime: Pure Python – uses
urllibfrom standard library (nocurlor other external tools).
Usage Guidance
This skill appears coherent and limited to downloading the Consumer Council's public pricewatch CSV (online-price-watch.consumer.org.hk) and doing local lookups. If you install it, note that: (1) it will make an outbound HTTPS request on first use to fetch the CSV; (2) it will create a data/ folder inside the skill directory and keep today's CSV (old files are removed automatically); (3) it runs with the agent's normal ability to invoke skills autonomously — if you prefer to review network activity first, run it in a sandbox or disable autonomous invocation. If you want extra assurance, inspect or run supermarket.py locally to verify the CSV URL and contents before enabling the skill.
Capability Analysis
Type: OpenClaw Skill
Name: hk-supermarket-shopping
Version: 1.2.3
The skill is a legitimate price comparison tool for Hong Kong supermarkets. It fetches data from the official Consumer Council Open Data portal (online-price-watch.consumer.org.hk) using standard Python libraries (urllib, csv). The code in supermarket.py is well-structured, lacks obfuscation, and contains no evidence of data exfiltration, malicious execution, or prompt injection.
Capability Assessment
Purpose & Capability
Name/description match the actual behavior: the skill fetches a public pricewatch CSV and performs price comparison. Manifest and code reference the same Consumer Council CSV URL. Minor manifest/version text inconsistencies (one embedded section references v1.2.2) are present but do not affect capability.
Instruction Scope
Runtime instructions and supermarket.py limit actions to downloading a single CSV from the Consumer Council, saving it under the skill's data/ directory, housekeeping old CSVs, and searching the CSV. The code does not read unrelated system files, environment variables, or other credentials.
Install Mechanism
No install spec included; runtime is pure Python using only the standard library (urllib, csv, pathlib). The only disk writes are to a data/ folder anchored to the skill directory (Path(__file__).parent / 'data'), consistent with README claims.
Credentials
The skill requests no environment variables, no credentials, and no external binaries. Network access is required (to a single documented Consumer Council URL) which is proportionate to the stated purpose.
Persistence & Privilege
The skill does not request always: true and does not modify other skills or system-wide configs. It writes only to its own data directory and performs normal housekeeping of those files.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install hk-supermarket-shopping - After installation, invoke the skill by name or use
/hk-supermarket-shopping - Provide required inputs per the skill's parameter spec and get structured output
