Codex v1 local-input note: This migrated skill supports local files and pasted text by default. References to Drive, CLM IDs, Slack, Westlaw, iManage, Ironclad, eDiscovery, dockets, or other remote systems require a separately configured Codex connector/MCP server. When a connector is unavailable, ask for a local export, local file path, or pasted excerpts. If config/local/codex-for-legal/<practice>/CLAUDE.md is missing, ask the user to run the relevant cold-start-interview or customize skill and copy from config/templates/codex-for-legal/<practice>/CLAUDE.md.
$commercial-legal: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 config/local/codex-for-legal/commercial-legal/matters/_archived/, never delete)
$commercial-legal:matter-workspace none — detach from any active matter, work at practice-level only
Instructions
Read config/local/codex-for-legal/commercial-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 $commercial-legal:cold-start-interview --redo and select a private-practice setting. Otherwise, you don't need $commercial-legal:matter-workspace at all." Don't error — the disabled state is the expected one for in-house users.
Use the subcommand logic below.
Dispatch on the first token of $ARGUMENTS:
new → run the intake interview, write config/local/codex-for-legal/commercial-legal/matters/<slug>/matter.md, seed history.md and .
notes.md
list → enumerate config/local/codex-for-legal/commercial-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 config/local/codex-for-legal/commercial-legal/matters/<slug>/ to config/local/codex-for-legal/commercial-legal/matters/_archived/<slug>/, log the close date in history.md.
none → set Active matter: to none — practice-level context only.
Show the user what changed and confirm before writing.
Notes
The skill never reads across matters unless Cross-matter context is on in the practice-level CLAUDE.md.
Archiving is not deletion — closed matters remain readable for retention/conflicts purposes.
Slugs are lowercase with hyphens. If a slug is reused across archived and active, the archived one is preserved under _archived/<slug>/.
Multi-client practitioners (private practice — solo, small firm, large firm) work across many matters. Context from one must not leak into another. This skill is the thin file-management layer that makes that true.
Default state is off. In-house users never see this — they run at practice-level only. Matter workspaces turn on at cold-start for private-practice users, or by editing ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗, this skill does not run; the workflow above explains the disabled state and suggests $commercial-legal:cold-start-interview --redo for users who actually need matter isolation.
Storage layout
All matter data lives under:
config/local/codex-for-legal/commercial-legal/
├── CLAUDE.md # practice-level practice profile
└── matters/
├── <slug>/
│ ├── matter.md # client, counterparty, matter type, key facts, overrides
│ ├── history.md # dated log of events, decisions, drafts, reviews
│ ├── notes.md # free-form working notes
│ └── outputs/ # skill outputs for this matter (optional subfolder)
└── _archived/
└── <slug>/ # closed matters — readable but not active
Slugs are lowercase with hyphens. Examples: acme-msa-2026, zenith-renewal, vendor-xyz-nda.
Active matter is in the practice CLAUDE.md
The Active matter: line under ## Matter workspaces in the practice-level CLAUDE.md is the single source of truth. Switching a matter edits that line. No separate state file.
Subcommand logic
new <slug>
Confirm slug is not already present in matters/<slug>/ or matters/_archived/<slug>/. If reused, ask the user to pick a different slug.
Run the intake interview:
Client (the party we represent, or the internal business unit if in-house)
Counterparty (the other side — may be multiple)
Matter type (read the plugin's practice profile for typical categories; for commercial-legal: vendor MSA | customer agreement | NDA | SaaS subscription | amendment | renewal | other)
Confidentiality level (standard | heightened | clean-team — heightened prompts extra care in cross-matter settings)
Key facts (2–5 sentences: what this matter is about, who the stakeholders are, what's at stake)
Matter-specific overrides to the practice playbook (e.g., "client requires 24-month LoL cap not 12", "counterparty is a strategic partner — relationship-preserving tone")
Related matters (slugs of any connected matters)
Write matters/<slug>/matter.md using the template below.
Seed matters/<slug>/history.md with a single "Opened" entry.
Create an empty matters/<slug>/notes.md.
Do not auto-switch to the new matter. Ask: "Want to switch to <slug> now? ($commercial-legal:matter-workspace switch <slug>)"
list
Enumerate matters/*/matter.md. Read each file's front-matter or first few lines to extract status. Print a table:
Slug
Client
Matter type
Status
Opened
Active
Mark the currently-active matter with *. Include _archived/* under a separate "Archived" heading if any exist.
switch <slug>
Confirm matters/<slug>/matter.md exists. If not, offer $commercial-legal:matter-workspace new <slug>.
Edit the Active matter: line in the practice-level CLAUDE.md to Active matter: <slug>.
Show the user the matter.md summary so they can confirm they're on the right matter.
close <slug>
Confirm matters/<slug>/ exists.
Append a "Closed" entry to matters/<slug>/history.md with today's date.
Move matters/<slug>/ → matters/_archived/<slug>/.
If the closed matter was the active matter, set Active matter: to none — practice-level context only.
none
Set Active matter: in the practice-level CLAUDE.md to none — practice-level context only. Confirm with the user.

Cross-matter context
The practice-level CLAUDE.md has a Cross-matter context: flag. When it's off (the default), a skill working in matter A never reads files in matters/B/ for any other B. Period. This is the confidentiality guarantee the setting exists to provide.
When it's on, a skill may read files across matter folders only when the user explicitly asks it to (e.g., "compare our position on liability caps across the last five vendor matters"). Even when on, the default is to load only the active matter unless the user asks for a cross-matter view.
What this skill does not do
Run a conflicts check. Conflicts are the practitioner's/firm's job; the intake captures what the user declares.
Enforce retention. Closing archives a matter; it does not delete. Retention policy is out of scope.
Auto-route outputs. The substantive skill decides where to write; this skill tells it which folder is active, not what to put in it.
Decide whether cross-matter is appropriate. It reads the flag and obeys.
