# Harness Improvement Loop

## Use this skill when
- the same class of issue keeps recurring
- generated work often needs the same correction
- verification is repeatedly weak
- handoffs are not good enough
- traces are insufficient for diagnosis

## Goals
- improve the harness instead of only fixing local artefacts
- reduce repeated waste
- strengthen planning, generation, evaluation, and handoff quality

## Process
1. Collect evidence from failures, traces, or weak reviews.
2. Classify the recurring pattern.
3. Identify the likely harness-level cause.
4. Propose a small high-leverage improvement.
5. Define rollout steps.
6. Define how to validate the improvement.

## Output contract
Return:
- recurring pattern
- evidence
- likely harness cause
- improvement proposal
- rollout plan
- success criteria
