SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill turns scattered litigation materials into a structured, dated chronology that can support briefing, reserve memo work, and witness preparation while applying a significance frame aligned to the matter theory.

Core Features & Use Cases

  • Chronology construction from declared sources: Extracts dated events from readable files (including emails, PDFs, and exports), attributes each event to its source, and records gaps when coverage is thin or files are inaccessible.
  • De-duplication and significance tagging: Merges repeated events across documents and tags each entry as 🔴/🟡/⚪ according to the pivot fact and key facts in matter theory.
  • Privilege posture gating and provenance: Forces a privilege-screening posture decision before extraction and flags entries for counsel review when sources may be privileged or uncertain.
  • Multiple output variants: Produces a working chronology by default and supports Statement-of-Facts and witness-specific filtered timelines on request.

Quick Start

Run chronology for slug acme-v-us-2026 and ask it to build a working chronology from the matter workspace and declared document sources.

Frequently Asked Questions about chronology

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a litigation timeline from a set of produced documents?

Build a litigation timeline by extracting dated events from declared document sources like PDFs and emails, de-duplicating repeated entries, and tagging each event by significance. The resulting chronology.md file provides a courtroom-ready timeline with versioned diffs.

What is a statement of facts timeline and when do I need one for litigation?

A statement of facts timeline is a filtered chronology sequencing dated events from case documents for briefing or witness preparation. You need one when converting a document production into a structured, SoF-ready narrative aligned with your case theory.

How do I de-duplicate events when extracting a chronology from multiple case documents?

De-duplicate chronology events by extracting dated occurrences across all declared sources and merging repeated entries. The process identifies overlapping events across emails, PDFs, and exports, consolidating them into single entries tagged by significance to the matter theory.

Does this chronology tool handle privilege review before extracting dated events?

Yes, a privilege-screening posture decision is required before extracting dated events. The tool forces a privilege posture gate that flags entries for counsel review when sources may be privileged or uncertain, ensuring protected materials are handled appropriately.

Can I generate witness-specific timelines from an existing legal chronology?

Yes, you can generate witness-specific filtered timelines from an existing legal chronology. By requesting a filtered variant, the tool outputs a timeline tailored to individual witnesses alongside the default working chronology and statement-of-facts formats.

What happens to gaps in coverage when building a case timeline from document productions?

When document coverage is thin or files are inaccessible, the chronology tool records and reports those gaps. Gap reporting identifies missing periods in the timeline, allowing counsel to seek supplementary productions before finalizing the statement of facts.
