matter-workspace

matter-workspace is a skill for Claude Code from ZekaiSuni/claude-for-legal-turkish. It costs 82 tokens per session (2,448 once invoked), scanned A, a copy of matter-workspace, Apache-2.0.

A workspace manager for separating the files and context of different clients or legal engagements. A matter is one specific client project or piece of work.

In plain words
What is it for?
Use it to create, list, switch, close, or detach client and engagement workspaces, with a short intake when creating a new matter.
Why use it?
Working on several matters in the same context can mix information between them. Separate workspaces make the active engagement clear and can archive closed matters without deleting them.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

matter-workspace scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/matter-workspace

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

Subcommands

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

Instructions

  1. Read ~/.claude/plugins/config/claude-for-legal/ai-governance-legal/CLAUDE.md — confirm the ## Matter workspaces section is populated. If Enabled is , tell the user: "Matter workspaces are off — you're configured as an in-house practice with one client, so the plugin works from practice-level context automatically. If you actually work across multiple clients, re-run /ai-governance-legal:cold-start-interview --redo and select a private-practice setting. Otherwise, you don't need /matter-workspace at all." Don't error — the disabled state is the expected one for in-house users.
  2. Use the workflow below.
  3. Dispatch on the first token of $ARGUMENTS:
    • new → run the intake interview, write ~/.claude/plugins/config/claude-for-legal/ai-governance-legal/matters/<slug>/matter.md, seed history.md and notes.md.
    • list → enumerate ~/.claude/plugins/config/claude-for-legal/ai-governance-legal/matters/*/matter.md, print a table, mark the active matter.
    • switch → update the Active matter: line in the practice-level CLAUDE.md.
    • close → move ~/.claude/plugins/config/claude-for-legal/ai-governance-legal/matters/<slug>/ to ~/.claude/plugins/config/claude-for-legal/ai-governance-legal/matters/_archived/<slug>/, log the close date in history.md.
    • none → set Active matter: to none — practice-level context only.
  4. Show the user what changed and confirm before writing.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
