dsh-sandbox-tester

Developing plugins for DeepSeek Harness can feel like walking a tightrope: all your code runs within the same host process. A single buggy line can cause a deadlock that freezes the entire application, an unhandled exception might crash it outright, and accidental deletions could wipe out your data and chat histories. This often leads to a frustrating cycle of restarts, connection errors, and wasted time. The dsh-sandbox-tester plugin is designed to shatter this cycle by providing a robust, process-level isolation sandbox. It creates completely independent sandbox instances—with their own processes, data directories, and network ports—where you can freely test plugins and patches. Any crash, error, or mistake remains contained within the sandbox, leaving your main DSH application and its data completely unharmed. The plugin offers a suite of intuitive tools for managing the entire lifecycle, from creation and injection to health checks and cleanup. A key innovation is its machine-enforced merge gate, which ensures that only code passing strict validation (including syntax and bundle checks) can be integrated back into the main application, effectively preventing dangerous changes from ever taking hold.
