Harness Engineering Framework

One-click initialization of a complete Harness Engineering framework in any project directory.

Based on insights from OpenAI (Codex), Anthropic (3-agent GAN architecture), and LangChain (self-verify loops), this skill sets up:

• 3-agent architecture: Planner (spec), Generator (build), Evaluator (test)
• Sprint contracts: Machine-verifiable "done" criteria before coding
• Quality hooks: Loop detection, pre-completion checklist, context injection
• Slash commands: /plan, /build, /qa, /sprint
• Golden principles: 10 non-negotiable rules enforced across all agents

When to Use

• Starting a new project and want structured AI-assisted development
• Want to set up Plan-Build-Verify-Fix workflow in current project
• User says "harness", "init harness", "setup framework", or similar
