What it does

Review is an agent skill from anthropics/claude-for-legal, published by the product's own GitHub organization. Review a vendor agreement, NDA, or SaaS subscription against your playbook. Identifies the agreement structure from titles, routes to the right review skill (vendor-agreement-review, nda-review, saas-msa-review), and integrates the output into a single memo. Use when the user says "review this contract", "check this MSA", "is this NDA okay", "look at this SaaS agreement", or attaches an inbound agreement for review.

Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Legal & Compliance, covering Contract review. The repository describes itself as: A suite of plugins for legal workflows. The licence is Apache-2.0.

When your agent uses it

  • The user says review this contract
  • Is this NDA okay
  • Look at this SaaS agreement
  • Attaches an inbound agreement for review

Example prompts

  • “review this contract”
  • “check this MSA”
  • “is this NDA okay”
  • “/review”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Load ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md. If placeholders present, stop and prompt: "Run…
  2. Get the agreement: From file path, Drive link, [CLM ID], or pasted text. If none provided, ask.
  3. Read the document structure — titles first.
  4. Select the skill(s) based on document structure.
  5. Confirm routing if enabled.
  6. Run the skill(s). Follow each skill's workflow fully. If multiple skills apply, run them in sequence and integrate the output into a…
  7. Check for escalations: If any issue exceeds the reviewer's authority per the ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLA…
  8. Offer follow-ups

What it can do on your machine

Read from SKILL.md and the folder at commit 4a6c651. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • drive.google.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Review loads about 1.4k tokens when it runs. Until then it costs about 107 tokens; SKILL.md has 501 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~107
When it runs · the whole SKILL.md, loaded when a task matches
~1.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Review a vendor agreement, NDA, or SaaS subscription against your playbook. Identifies the agreement structure from titles, routes to the right review skill (vendor-agreement-review, nda-review, saas-msa-review), and integrates the output into a single memo. Use when the user says "review this contract", "check this MSA", "is this NDA okay", "look at this SaaS agreement", or attaches an inbound agreement for review.

/review

Reviews an inbound agreement against the playbook in ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md. Identifies the agreement structure from titles, selects the appropriate skill(s), and — if confirm_routing is enabled — checks with the user before proceeding.

Instructions

  1. Load ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md. If placeholders present, stop and prompt: "Run /commercial-legal:cold-start-interview first — I need to learn your playbook before I can review against it."

    Also read ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md → ## Review preferences → confirm_routing. If the field is missing, treat it as true.

  2. Get the agreement: From file path, Drive link, [CLM ID], or pasted text. If none provided, ask.

  3. Read the document structure — titles first.

    Before reading the body, extract:

    • The main agreement title (e.g., "Master Services Agreement", "Non-Disclosure Agreement")
    • All exhibit, schedule, addendum, and attachment titles (e.g., "Exhibit A — Data Processing Addendum", "Schedule 1 — Subscription Order Form", "Annex B — Service Level Agreement")

    This is the routing signal. Do not rely on body keywords alone — a 40-page MSA with "confidential" throughout is not an NDA.

  4. Select the skill(s) based on document structure.

    Map each identified document or section to a skill:

    Document / section title containsSkill
    Non-Disclosure, NDA, Confidentiality Agreement (as the main agreement)nda-review
    Master Services Agreement, Professional Services, Statement of Work, Consulting Agreementvendor-agreement-review
    Subscription, SaaS, Cloud Services, Order Form with auto-renewal, Software License with recurring feessaas-msa-review (overlay on vendor-agreement-review)
    Data Processing Addendum, DPA, Data Processing Agreement (as exhibit or standalone)note for vendor-agreement-review → data protection section
    Service Level Agreement, SLA (as exhibit)note for saas-msa-review → SLA section

    Multiple skills may apply. Common combinations:

    • MSA + DPA exhibit → vendor-agreement-review, with DPA noted
    • SaaS subscription + Order Form + SLA exhibit → saas-msa-review (covers all three)
    • MSA + Order Form with auto-renewal → vendor-agreement-review + saas-msa-review overlay

    When the structure is genuinely ambiguous after reading titles (e.g., a document titled "Agreement" with no exhibits listed), read the first two pages of the body to resolve it — then stop and route.

  5. Confirm routing if enabled.

    If confirm_routing is true in ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md (or field is absent):

    I'm going to review this as: [agreement type(s)].
    
    Documents identified:
    - [Main agreement title] → [skill]
    - [Exhibit A title] → [how it will be handled]
    - [Exhibit B title] → [how it will be handled]
    
    Sound right? (yes / no — or tell me what I got wrong)

    Wait for confirmation before proceeding. If the user corrects the routing, apply their instruction and proceed.

    If confirm_routing is false: proceed silently. Log the routing decision at the top of the review memo so the user can see what was applied.

  6. Run the skill(s). Follow each skill's workflow fully. If multiple skills apply, run them in sequence and integrate the output into a single memo — don't produce separate memos.

  7. Check for escalations: If any issue exceeds the reviewer's authority per the ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md matrix, invoke escalation-flagger to route and draft the ask.

  8. Offer follow-ups:

    • Stakeholder summary for the business owner
    • Redline .docx with tracked changes
    • [CLM] record creation (if connected)
    • Add to renewal register (if auto-renewal found)
Show full SKILL.md (60 more words)Show less

Configuring confirm_routing

Add to ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md → ## Review preferences:

markdown
## Review preferences

confirm_routing: true   # Set to false to skip routing confirmation and proceed automatically

The cold-start interview should ask about this preference. Default is true — confirmation on. As trust builds, the user can set it to false.

Examples

/commercial-legal:review vendor-msa.pdf
/commercial-legal:review https://drive.google.com/file/d/ABC123
/commercial-legal:review
[paste agreement text]

Output

Full review memo per the skill's format. Routing decision logged at the top. Deviation-by-deviation, specific redline language, named approver. Saved where ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md → House style says work product goes.
