🧠 What Is PEV-Harness? Thinking Before Building, Verifying After Creating

Imagine a master architect who never lays a single brick without first studying the blueprint, and never considers a wall complete until the structural engineer has signed off. That architect is PEV-Harness—a native Plan-Execute-Verify (PEV) coding harness designed specifically for Claude Code and other large language model agents.

PEV-Harness transforms chaotic, single-pass AI coding sessions into disciplined, multi-phase production pipelines. Instead of allowing your AI assistant to generate code in one shot and hope for the best, PEV-Harness enforces a **three-phase cognitive loop**:

1. Plan Phase — The AI must articulate its approach, identify dependencies, list potential edge cases, and estimate complexity before writing a single line.
2. Execute Phase — Code generation proceeds, but only within the boundaries established during planning.
3. Verify Phase — A hook-driven verification system checks outputs against pre-established criteria, running tests, validating schemas, and confirming that the execution matches the plan.

This repository is not just a tool—it is a **methodology** for reliable AI-assisted software development. It transforms your AI coding assistant from a reckless intern into a disciplined senior engineer.
