Han Jr System (小翰系统) is an advanced automation suite designed to streamline interactions with 1688.com, China's leading B2B procurement platform. This skill empowers users to automate supplier research, lead generation, and inquiry processes while adhering to a 'Quality Over Speed' philosophy. Unlike simple scrapers, this system mimics human navigation patterns using Playwright and Chrome CDP, ensuring high reliability. The core architecture focuses on sequential, single-supplier engagement, meaning it contacts suppliers one by one, verifies the action through OCR, and handles anti-crawling challenges automatically.
Installation
To integrate this skill into your OpenClaw environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/damianleemoha/han-jr-system
Ensure you have a modern Chrome browser installed and the necessary Python dependencies available by running: pip install playwright requests beautifulsoup4 easyocr pillow numpy playwright install chromium
Use Cases
- Bulk Sourcing: Automatically identify and contact 5-10 suppliers for specific industrial components (e.g., '铅笔' or 'dgx spark').
- Inquiry Automation: Standardize the message format sent to suppliers regarding pricing, availability, and lead times.
- Verification-Led Procurement: Ensure that every contact attempt is logged and verified via screenshots and OCR to confirm the message was successfully dispatched.
- Resilient Research: Overcoming anti-crawling obstacles such as slider captchas during mass-market analysis.
Example Prompts
- "Han Jr System, please search for 5 suppliers of high-quality stainless steel pens on 1688 and send them an inquiry regarding bulk pricing and minimum order quantities."
- "I need to find manufacturers for 'dgx spark' components. Use the han-jr-system to compile a list of top 5 suppliers and initiate a contact sequence."
- "Execute the full pencil_workflow to contact verified vendors and confirm receipt of my inquiry, ensuring that any captcha blocks are handled automatically."
Tips & Limitations
- Sequential Integrity: The system emphasizes 'contact one by one.' Do not attempt to parallelize these tasks as it increases the risk of being blocked by 1688's security algorithms.
- Handling Captchas: If the system hits a 'Sorry, we have detected unusual traffic' message, it will trigger the
slider_captcha.pyscript. Keep your selector configurations updated if the website structure changes. - Verification: Always trust the OCR-based verification results over assumptions. If a message is not verified by the screenshot, the system will re-attempt it according to the double-check protocol.
- Rate Limiting: Always maintain a 3-5 second delay between searches to keep the account activity within safe, human-like parameters.
