## What it does

The skill loads the matter workspace: `matter.md` for the narrative intake, `history.md` for the event log, and the matching row from `_log.yaml`. It also reads the plugin's `CLAUDE.md` so a risk rating means something calibrated instead of generic. Output covers current posture, what changed, the next deadline, open questions, and a check on whether the `risk:` field still reflects reality.

There is a hard gate. If the matter slug is missing from `_log.yaml`, the skill refuses and tells you to run `/litigation-legal:matter-intake` first, because the conflicts check has to run before any briefing. When `last_updated` is older than 30 days, the briefing carries a staleness flag and suggests `/litigation-legal:matter-update` after the meeting.

This one reads, it does not write. No outcome predictions, no strategy advice, no re-triage — that last part belongs to `/matter-update` with field changes. A newly opened matter gets a short briefing, and that is the intended behaviour rather than a gap.

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/anthropics/claude-for-legal/tree/HEAD/litigation-legal/skills/matter-briefing/SKILL.md

## When to use it
- prep for a call with outside counsel
- see what changed on a matter since the last update
- check whether the current risk rating still holds
- surface the next deadline and open questions
- assemble a matter status for a GC update

## Example prompts
- brief me on acme-v-jones
- where are we on acme-v-jones
- brief me on acme-v-jones before the call with outside counsel

description: Deep briefing on one matter — current posture, what's changed, next deadline, open questions, and a risk re-assessment check, ready before a GC update or outside counsel call.

# /matter-briefing

1. Load `~/.claude/plugins/config/claude-for-legal/litigation-legal/CLAUDE.md` → risk calibration + relevant stakeholders.
2. Follow the workflow and reference below.
3. 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`.
4. 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?").
5. 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-intake` first 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

```markdown
[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`]
