SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Contracts accumulate amendments, and it becomes hard to remember what the base agreement originally said versus what the latest controlling language now requires.

Core Features & Use Cases

  • Chronological amendment summaries: Produces a timeline of what changed across the base agreement and subsequent amendments.
  • Clause-level provision tracing: Follows a specific clause (e.g., indemnity, liability cap, termination, privacy/DPA, IP, payment) through each touched version to identify current controlling language with exact quotes.
  • Citation and watch items: Includes inline section references on each finding and flags inconsistencies such as conflicting amendments, section shifts, party name changes, or modifications to provisions that appear deleted.

Quick Start

Ask the skill to trace the latest version of a clause by running: /commercial-legal:amendment-history --provision indemnity
