dsh-skill-7d-code-reviewer: Adding Templated Code Review to DSH Sessions

`7dgroup-ai/dsh-skill-7d-code-reviewer` is a template-driven code review plugin designed specifically for DeepSeek Harness (DSH). It aims to address issues such as unstable review scope, inconsistent levels, and format inconsistencies caused by ad-hoc prompts. Licensed under MIT, the current version is `0.1.0-rc.5`, and it requires Node 22+ and pnpm 10+ environments. Installation follows GitHub specifications to circumvent build script restrictions. Its core capabilities include: separating review content (SKILL.md) from presentation templates (HTML); executing a five-step process that involves task acceptance, quick scanning, line-by-line review, grading, and report generation; and providing fixes based on three severity levels—Critical, Medium, and Minor.
