dsh-test-insight: Test Plan Generation Plugin for DeepSeek Harness Repository Facts and Change Risk

dsh-test-insight is a test insight plugin for DeepSeek Harness that analyzes code structure and change risks to automatically generate reviewable test plans (TEST-PLAN.md) and isolated test drafts, helping developers quickly identify test gaps. It supports three analysis modes—full repository, change-driven, and target file analysis—and provides programmatic invocation capabilities. Its core security features include read-only behavior by default, explicit authorization required for execution, drafts marked as “review only,” and strict protections against file overwriting, ensuring the safety and controllability of the testing process.
