Remove noise, redundant content, dead fields, or sensitive details while preserving the core artifact. Use when Codex needs to sanitize output, deduplicate material, delete non-essential parts, or prepare a safe cleaned version of something. Also use for Chinese requests such as 清理噪音, 删除冗余内容, 脱敏, 去掉无用字段, or 保留核心信息重新整理.

Remaining risks instead of erasing it aggressively.references/mental-model.md for the cleanup-vs-redaction split.references/cleanup-format.md for the canonical cleanup schema.references/workflows.md for common cleanup flows.references/anti-patterns.md for trigger boundaries.
