Legal/TOS Diff-er

Fetches Terms of Service documents, stores snapshots, and performs semantic diffing to identify meaningful legal changes across Privacy Risks, Financial Changes, and User Rights categories.

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

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