What Content Hash Cache Pattern does

Content Hash Cache Pattern caches expensive file processing results using SHA-256 content hashes instead of file paths, so cached results survive file moves and invalidate automatically on content changes. Use it when building file processing pipelines, CLIs with cache flags, or adding caching to pure functions.

Content Hash Cache Pattern is cataloged under DevOps on DirSkills. Content Hash Cache Pattern comes from a repository tagged ai-agents, anthropic, claude, claude-code and developer-tools.

Documentation

README

Excerpt

内容哈希文件缓存模式 (Content-Hash File Cache Pattern)

使用 SHA-256 内容哈希（而非文件路径）作为缓存键，缓存高昂的文件处理结果（如 PDF 解析、文本提取、图像分析）。与基于路径的缓存不同，这种方法在文件移动/重命名后依然有效，并在内容变化时自动失效。

何时激活

构建文件处理流水线（Pipeline），如 PDF、图像或文本提取
处理成本高昂且需要重复处理相同文件
需要提供 --cache/--no-cache 命令行选项
希望在不修改现有纯函数（Pure Functions）的情况下为其添加缓存功能

核心模式

1. 基于内容哈希的缓存键
