dsh-mp-automator: A WeChat Mini Program Automated Testing Plugin

The `dsh-mp-automator` plugin released by DeepSeek Harness (DSH) aims to address key challenges in agent-driven WeChat Mini Program testing: environment changes have a significant impact, and pure text models struggle to infer screen state. By introducing “discipline layer” designs—including selector addressing, build freshness gates, and fail-closed mechanisms—it ensures the accuracy and reliability of test actions. It provides eight tools, including session management, element querying, action execution, and screenshots, and supports geometric assertions and camera-free QR code scanning, offering the necessary components for agents to test Mini Programs securely and reliably.
