SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you quickly build an accurate, date-ordered chronology from litigation evidence and case files, reducing manual timeline reconstruction and improving fact traceability for legal drafting.

Core Features & Use Cases

  • Date-based event extraction with source attribution: Extracts events carrying dates from provided and configured materials, and labels each entry with its origin.
  • Deduplication and unified timeline: Merges the same event appearing across multiple documents while aggregating all sources for that event.
  • Case-theory importance tagging: Assigns relevance importance to each event for plaintiff/prosecution vs defendant/defense framing to support narrative building.
  • Output persistence and version diffing: Writes results to the case folder chronology.md and summarizes diffs when a prior version exists.

Typical use cases include: drafting the facts section of an argument, preparing an evidentiary timeline for hearings, producing witness-/party-specific time tracks, and answering questions like “what happened when” based strictly on materials.

Quick Start

Tell the agent: “From the evidence files and the configured matter context, extract a chronology timeline and store it to the case’s chronology.md, marking 🔴/🟡/⚪ and listing source paths.”

FAQPage Schema
How do I build a litigation timeline from multiple evidence files?

A litigation chronology is built by extracting date-bearing events from your case materials, deduplicating across documents, tagging importance per case theory, and writing a unified timeline to chronology.md.

Can I tag case events by importance for plaintiff vs defendant framing?

Case-theory importance tagging assigns relevance levels to each event for plaintiff or defendant framing, directly supporting narrative building for pleadings, witness preparation, and dispute fact sections.

How does deduplication work when the same event appears across multiple documents?

Deduplication merges identical events found across multiple documents while aggregating all source paths, ensuring each chronology entry retains full evidentiary attribution without duplicate timeline rows.

What is source attribution in a case chronology and why does it matter?

Source attribution labels each extracted event with its origin file path, ensuring fact traceability so legal teams can verify chronology entries against original evidence during drafting and hearings.

Does the chronology tool track changes when updating an existing case timeline?

Version-aware diffing compares new extractions against any prior chronology.md in the case folder and summarizes differences, so you can review exactly what was added or changed.
