Legal/TOS Diff-er

跟踪服务条款等法律文档：通过 node handler 添加/列出/抓取/移除 URL 并保存带时间戳的快照；diff 命令抓取当前版本并输出与上一快照的语义比较提示，由 Claude Code 运行时按隐私风险、财务变更、用户权利分类分析变化。

Legal/TOS Diff-er

This skill tracks changes in Terms of Service and legal documents by fetching pages, extracting the legal text, and comparing versions semantically.

What It Does

Fetches legal documents from tracked URLs
Extracts clean legal text, stripping navigation, ads, and page noise
Stores timestamped snapshots for historical comparison
Compares versions using semantic analysis (not just text diffs)
Categorizes changes into Privacy Risks, Financial Changes, and User Rights

How It Works

Use add_url to start tracking a legal document
Use fetch_current to capture the first snapshot
Later, use diff to fetch the current version and compare it against the previous snapshot
The Claude Code runtime receives a structured comparison prompt and performs the semantic analysis

Change Categories
