SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Contracts change over time through amendments, and the controlled language for any clause often becomes unclear when multiple versions exist. This Skill reconstructs amendment history so you can quickly understand what changed, when it changed, and what governs today.

Core Features & Use Cases

  • Chronological amendment tracking: Loads a base agreement and all amendments, orders them correctly, and identifies what each amendment modifies, adds, or deletes.
  • Two analysis modes: Produces either (1) a full chronological summary of amendments across the agreement or (2) a clause-by-clause provision trace showing the exact evolution of controlling language.
  • Section-anchored verification: Every finding includes inline section references and quotes of prior and replacement language for auditability.

Quick Start

Run the command to summarize changes across an uploaded base agreement and its amendments by calling: amendment-history with your agreement files.

FAQPage Schema
How do I trace changes to a specific clause across multiple contract amendments?

To trace changes to a specific clause across contract amendments, you need a tool that parses your base agreement and amendments chronologically, extracting exact modifications to produce a clause-by-clause provision trace with section-referenced quotes of prior and replacement controlling language.

What's the best way to summarize all modifications made to a contract over time?

Summarizing all contract modifications over time requires loading the base agreement and subsequent amendments, ordering them chronologically, and indexing explicitly modified provisions to generate a full chronological summary of what each amendment changed, added, or deleted.

How do I find the current controlling language for an indemnity or termination provision after several amendments?

Finding the current controlling language for provisions like indemnity or termination requires tracing the clause's evolution through all amendments in chronological order, extracting the final replacement text with inline section references for auditability.

Can I see what exact text was replaced when a contract amendment modifies a section?

Yes, seeing exact replaced text requires parsing amendments to identify modified provisions, then outputting section-anchored verification that includes inline quotes of both the prior language and the replacement controlling language for audit purposes.

Does contract amendment tracking work for complex provisions like privacy/DPA or IP clauses?

Contract amendment tracking works for complex provisions like privacy/DPA or IP clauses by parsing uploaded document versions chronologically, extracting execution details, and indexing explicitly modified provisions to trace the evolution of controlling language with exact quotations.

What do I need to provide to analyze a contract's amendment history?

To analyze a contract's amendment history, you need to upload the base agreement and all subsequent amendment documents, which the system then parses in chronological order to extract execution details, party information, and index explicitly modified provisions.
