type:audit

Audit and repair a kohya-style LoRA dataset before training. Use when the user asks to check, validate, inspect, fix, clean, 体检, or 修 a dataset, captions, or tags. Inspect image count, repeats and step budget, resolution and aspect buckets, duplicates, corrupt or non-RGB images, missing or empty captions, trigger consistency, and tag-frequency hygiene. Return a structural PASS, WARN, or FAIL report and apply only confirmed fix_dataset.py actions, dry-run first with displaced originals quarantined.

From the source SKILL.md

在训练前对 LoRA 数据集与标注做结构/卫生预检，给出 PASS / WARN / FAIL 结论和按优先级排序的修复建议；PASS 不代表图像与 caption 的语义已经人工验证。确认后用 fix_dataset.py 一行命令执行修复。体检只读；修复默认 dry-run，加 --apply 才动文件，且从不删除——被移除的文件全部进数据集内的 _quarantine/（体检与训练都会忽略它），随时可还原。任何 --apply 都必须先得到用户确认。
