cwijayasundara/claude_harness_eng_v6 ? reverse-engineered prompt

Build me a Claude Code plugin that helps me change software with a generator and evaluator loop, quality gates, and a required human review before anything gets merged.

I want it to be installable from a local marketplace so I can keep it loaded across sessions, and I want a simple scaffold command that sets up a lean default version in a project, with an option to install the full set of features when needed. It should have clear workflow commands for planning, making changes, checking work, and gating before merge, plus built in hooks so the checks actually run instead of just being documented.

Please make the setup easy to use from a fresh clone, include the docs I would need to understand how to install and use it, and keep the structure clean so the core part stays separate from optional extras. If you need current Claude Code plugin details, look them up online first.
