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

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
