- Load
~/.claude/plugins/config/claude-for-legal/litigation-legal/CLAUDE.md→ risk calibration + relevant stakeholders. - Follow the workflow and reference below.
- Read
~/.claude/plugins/config/claude-for-legal/litigation-legal/matters/[slug]/matter.md+~/.claude/plugins/config/claude-for-legal/litigation-legal/matters/[slug]/history.md+ log row from_log.yaml. - Produce briefing: current posture, what's changed since last update, next deadline, open questions, risk re-assessment check ("does the
risk:field still reflect reality?"). - Flag staleness: if
last_updated> 30 days, say so.
Matter Briefing
Purpose
Give the counsel a clean read on one matter in the time it takes to walk to a conference room. Current posture, what's changed, what's next, what's worth reconsidering.
Load context
~/.claude/plugins/config/claude-for-legal/litigation-legal/matters/_log.yaml— structured row~/.claude/plugins/config/claude-for-legal/litigation-legal/matters/[slug]/matter.md— narrative intake~/.claude/plugins/config/claude-for-legal/litigation-legal/matters/[slug]/history.md— event log~/.claude/plugins/config/claude-for-legal/litigation-legal/CLAUDE.md— risk calibration (so "risk: high" means something specific, not generic)
Conflicts gate — unbypassable. Before briefing, check _log.yaml for the matter slug. If the matter is not in _log.yaml, refuse and route:
"I don't see [matter slug] in the matter log. Run
/litigation-legal:matter-intakefirst so the conflicts check runs and the matter workspace is set up. I won't build a briefing on a matter that hasn't been intaken — the conflicts check is the gate."
Input
Slug (required). If ambiguous or missing, ask the user to pick from a list of active matters.
The briefing
[WORK-PRODUCT HEADER — per plugin config ## Outputs — differs by role; see `## Who's using this`]
# [Matter Name] — Briefing as of [today]
**Status:** [status / stage]
**Risk:** [rating] ([severity] × [likelihood])
**Materiality:** [category]
**Outside counsel:** [firm — lead]
**Last updated:** [date] [flag ⚠️ STALE if >30d]
**Conflicts:** [status — flag ⚠️ if `pending` or `not-run`]
---
## One-paragraph summary
[Current posture. What are we doing and why. Name the pivot fact if one is captured.]
## What's changed recently
[Last 3-5 entries from history.md, most recent first. If history is thin, say so.]
## What's next
- **Immediate deadline:** [next_deadline + what it is]
- **Upcoming milestones:** [anything dated in matter.md or recent history]
- **Decisions pending:** [open questions flagged in matter.md]
## Exposure
[Range + any change since intake. If reserved, current reserve + whether recalibration is overdue.]
## Internal owners
[Who's looped in; whether anyone should be looped in and isn't]
## Risk re-assessment check
*A prompt, not an answer.*
- Does `risk: [rating]` still feel right, or has the case moved?
- Does `materiality: [category]` still match? (New facts might push toward reserve or disclosure.)
- Any new stakeholder the matter needs (e.g., CISO becomes relevant after a discovery development)?
## Open questions
[From matter.md and anything unresolved in history]
## For the conversation
[If user specified a purpose — "brief me before the call with outside counsel" — tailor the final section: questions to ask, decisions to get, updates to extract. If no purpose given, omit this section.]
Staleness
If last_updated > 30 days ago: flag at the top AND suggest running /litigation-legal:matter-update [slug] after the meeting to capture whatever's discussed.
Tone
This is not marketing. Say what's known; flag what's not. If a matter has thin history and was just opened, the briefing is short — and that's correct. Don't pad.
Close with the next-steps decision tree
End with the next-steps decision tree per CLAUDE.md ## Outputs. Customize the options to what this skill just produced — the five default branches (draft the X, escalate, get more facts, watch and wait, something else) are a starting point, not a lock-in. The tree is the output; the lawyer picks.
What this skill does not do
- Predict outcomes. Risk rating is a captured judgment, not a forecast.
- Recommend strategy. Surfaces questions; the counsel answers them.
- Re-triage. If the user wants to re-triage, that's an
