SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Contracts accumulate amendments over time, and by the third amendment nobody remembers what the original said or which version of a clause controls. This Skill reads a base agreement and all its amendments in chronological order to reconstruct what changed and what language currently governs. ## Core Features & Use Cases - Summary Mode: Produces a chronological report of every material change across all amendments, plus a net current-state table with section references. - Provision Trace Mode: Traces a specific clause (e.g., indemnity, liability cap, termination) through every version with exact quotes, ending in the current controlling language. - Watch Items: Flags inconsistencies such as amendments modifying deleted provisions, contradictory language, or party name changes without formal assignment. - Use Case: A lawyer uploads an MSA plus three amendments and asks "where's the latest indemnity clause" — the Skill quotes each version and identifies the controlling text. ## Quick Start Upload the base agreement and all amendment files, then ask the assistant to show the amendment history or trace a specific provision like indemnification.

FAQPage Schema
How do I find the current version of a clause in an amended contract?

Use provision trace mode by naming the clause, such as "where's the latest indemnity" or "how has the liability cap changed". The Skill quotes each version of the provision across the base agreement and amendments, then identifies the current controlling language with its section reference.

How do I summarize all changes made to a contract over time?

Upload the base agreement and all amendments, then ask for the amendment history or what changed over time. The Skill produces a chronological summary of material changes per amendment plus a net current-state table showing each provision's latest position.

Does the amendment history tool determine which document controls in a conflict?

No. The Skill flags conflicts between the base agreement and amendments but does not resolve them, since that is a legal interpretation question. It quotes language exactly and routes conflicts to Legal for judgment.

What happens if my contract files have no clear ordering?

The Skill infers chronological order from execution dates, document headers, recitals, and titles like "Amendment No. 1". It only asks you to confirm ordering when filenames and dates give no indication of sequence or two documents appear to be the same version.

Can I trace a provision that was never amended?

Yes. If the provision was never modified after the base agreement, the Skill reports that the original language controls and cites the section number and base agreement date rather than fabricating a change history.
