Use harness-engineering when a repository needs clearer maps, validation lanes, and drift control. It audits repo legibility and scaffolds durable repo docs so agents can work with stronger guardrails. Reach for meta-harness instead when the goal is benchmarked harness.py optimization.

Quick start

Run from the repo root:
In Claude Code:

When to reach for meta-harness

  • You are optimizing one benchmarked LLM task.
  • The main artifact is a candidate harness.py.
  • You need Pareto / frontier tracking across prompt or retrieval variants.
  • The bottleneck is evaluation quality, not repo operating clarity.
