It handles the complete workflow from QR code detection to invoice submission. ## Workflow ### Step 1: QR Code Recognition When a user provides an invoice receipt image containing a QR code: 1. Run the QR code recognition script: ```bash node scan-qr.js <image-path> ``` 2. The script outputs the decoded QR code URL 3. If recognition fails, ask user to provide the URL directly ### Step 2: Navigate to Invoice System 1. Open the decoded URL in browser automation 2. Verify the page loads successfully 3. Take snapshot to understand form structure ### Step 3: Retrieve Company Information Before filling the form, retrieve the user's company information: 1. Check memory files for stored invoice header information: - Search `memory/YYYY-MM-DD.md` for recent invoice info - Check `MEMORY.md` for long-term stored details 2. Required fields typically include: - Company name (公司名称) - Tax ID/Unified Social Credit Code (税号) - Address (地址) - Phone number (电话) - Bank name (开户行) - Bank account number (银行账号) ### Step 4: Fill Invoice Form 1. Analyze the form structure using browser snapshot 2. Fill in company information fields 3. Fill in recipient information: - Phone number (手机号) - Email address (邮箱) 4. Verify all required fields are completed ### Step 5: Review and Submit 1. Submit the form 2. Review confirmation page 3. Verify all information is correct 4. Report results to user ## Error Handling ### QR Code Not Recognized If QR code recognition fails: 1. Ask user to provide the URL directly 2. Suggest using phone to scan and share the URL ### Form Structure Changes If the invoice system form structure changes: 1. Take a new snapshot 2. Identify updated field references 3. Adapt the filling process accordingly 4. Document the new structure for future reference ### Missing Information If required company or contact information is missing: 1. Ask user to provide the missing details 2. Update memory files with new information 3. Continue with the invoice application ## Scripts ### scan-qr.js Primary script for QR code recognition from images using Node.js and qrcode-reader library. **Usage:** ```bash node scan-qr.js <image-path> ``` **Requirements:** - Node.js environment (v14+) - npm packages: `qrcode-reader`, `canvas` **Installation:** ```bash cd scripts npm install qrcode-reader canvas ``` **Output:** - Decoded QR code URL on success (format: "✅ 识别成功: <url>") - Error message on failure (format: "❌ 错误: <error message>") **Technology:** - Uses qrcode-reader library for QR code decoding - Canvas for image processing - Pure JavaScript implementation (no Worker required) ## Memory Integration This skill relies on stored user information in memory files: **Company Invoice Header Information** (stored in MEMORY.md): - Company name - Tax ID - Address - Phone number - Bank information **Contact Information** (stored in MEMORY.md): - Mobile phone numbers - Email addresses When filling forms, always reference this information first before asking the user. ## Best Practices 1. **Always verify** the decoded URL is legitimate before proceeding 2. **Double-check** all information before submission 3. **Take snapshots** at each step for documentation 4. **Report results** clearly to the user after submission 5. **Update memory** with new information if user provides corrections 6. **Use auto-complete** when available (more accurate than manual input)
