## Description

Manage matter workspaces, new, list, switch, close, or detach (practice-level). Use when a multi-client practitioner needs to create a matter, switch the active matter, list matters, archive a matter, or detach to practice-level context, or when another skill needs to know which matter it's working in.

# /matter-workspace

Practitioners work across multiple clients and matters. A matter workspace keeps one client or engagement's context separate from every other. This command manages those workspaces.

## Subcommands

- `/commercial-legal:matter-workspace new <slug>`, create a new matter workspace, run a short intake, write `matter.md`
- `/commercial-legal:matter-workspace list`, list matters with status and active flag
- `/commercial-legal:matter-workspace switch <slug>`, set the active matter
- `/commercial-legal:matter-workspace close <slug>`, archive a matter (move to `~/.claude/plugins/config/claude-for-legal/commercial-legal/matters/_archived/`, never delete)
- `/commercial-legal:matter-workspace none`, detach from any active matter, work at practice-level only
