SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you reconstruct a contract’s amendment history—either as a complete timeline of changes or as clause-by-clause tracking—so you can see what changed and what language is currently effective.

Core Features & Use Cases

  • All-amendments timeline summaries: Produce an ordered summary of each amendment, highlighting the purpose and substantive clause changes over time.
  • Clause tracking (“where is the current clause?”): Follow a specific clause or topic (e.g., indemnity, limitation of liability, termination, privacy/data protection, IP, payment, renewal) from the base agreement through all revisions, showing exact before/after quotations.
  • Current effective status + issue flags: Summarize the present standing with section references and flag inconsistencies, naming changes, or contradictions for attorney review.

Quick Start

Upload the base agreement and all amendment versions, or paste the texts, then ask the skill to display the contract’s amendment history or track a specific clause.
