Harness Project

Codex harness starter based on the “Harness Engineering” lecture deck.

Goal

Turn a short user request into a repeatable three-agent workflow:

1. Planner expands the request into SPEC.md.
2. Generator implements the deliverable and writes SELF_CHECK.md.
3. Evaluator grades the result and writes QA_REPORT.md.

The loop repeats until the result passes or the retry budget is exhausted.

Quick Start

cd harness-project

Then give one short request such as:

Operating Rules

• Do not skip files that the next stage depends on.
• Do not invent relaxed criteria outside the role documents.
• Generator must apply evaluator feedback directly.
• Evaluator must stay strict and avoid lenient scoring.
