Introduction to the DeepSeek Harness Strict Gate Plugin

The DeepSeek Harness plugin Strict Gate enforces policies that convert an agent’s “self-management” into a Harness-level oversight mechanism, ensuring that code changes on critical paths comply with established standards. It includes three core capabilities: repeated-failure intervention, critical-path protection gating, and automatic post-generation syntax checks. The plugin runs on Node.js, requires the `dsh-tool-strict-check` dependency, and is enabled through configuration. It is designed to consolidate code-generation risk under unified management by intercepting repeated errors, protecting core code, and performing immediate syntax checks, making it suitable for project processes that require strict governance.
