SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Matter records go stale when updates are logged ad hoc, so this Skill streamlines capturing new developments and ensuring the matter’s history and log stay consistent and audit-friendly.

Core Features & Use Cases

  • Structured, dated history entries: Captures the event type, date, and a concise summary, then appends it to the matter’s history.md in the correct place.
  • Portfolio log refresh with field updates: Updates _log.yaml (including last_updated) and applies relevant field changes like status, stage, risk, materiality, exposure range, next deadlines, and ownership/hold changes.
  • Safety and compliance gates: Enforces an unbypassable conflicts gate (refuses to write to history if the matter slug isn’t present in _log.yaml) and runs additional settlement-acceptance and materiality reclassification prompts when required.
  • Materiality re-check triggers: Forces explicit user confirmation for substantive events, strategy shifts (including settlement activity), risk re-assessments, and regulatory/enforcement developments so the user can’t accidentally skip a required disclosure posture change.

Quick Start

Run matter-update with the matter slug and a brief description of the new event to append it to the correct history and update the matter log.

Frequently Asked Questions about matter-update

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

FAQPage Schema
How do I log litigation history updates while keeping the matter log consistent?

Matter update logging works by capturing the event type, date, and summary, then appending it to history.md and refreshing the _log.yaml portfolio log. This structured approach ensures consistency across procedural, discovery, substantive, strategy, and administrative developments.

What fields can I automatically update when logging a new matter development?

When logging a new matter development, you can automatically update impacted fields in _log.yaml including status, stage, next deadlines, risk level, materiality, exposure range, owners, and legal hold status. This ensures the portfolio log reflects current matter conditions accurately.

How does materiality tracking work when logging substantive or strategy events?

Materiality tracking enforces explicit user confirmation prompts for substantive events, strategy shifts, settlement activity, risk re-assessments, and regulatory developments. This materiality re-check trigger prevents accidentally skipping a required disclosure posture change during the update logging process.

Can I use this matter management Skill if the matter slug is not in the log file?

No, you cannot use this Skill if the matter slug is missing from _log.yaml. An unbypassable conflicts gate refuses to write to history if the slug is not present, preventing unauthorized or mismatched entries from corrupting your litigation portfolio records.

What is the best way to record settlement authority changes in a litigation portfolio?

The best way to record settlement authority changes is through this Skill's enforced settlement-acceptance prompt, which requires explicit user confirmation before writing the update. This ensures settlement activity is properly logged in history.md and triggers materiality reclassification checks.

Do I need user confirmation before matter updates are written to history and log files?

Yes, user confirmation is required before any updates are written. The Skill displays the proposed entry and diff for history.md and _log.yaml, writing the changes only after the user explicitly confirms the displayed modifications are accurate and acceptable.
