Claude for Legal is a collection of AI agents, skills, and data connectors for legal work such as commercial, privacy, employment, litigation, regulatory, and intellectual-property matters. Lawyers and legal teams use it through Claude Cowork, Claude Code, or the Claude Managed Agents API, with attorney review required for every output. The catalogue entries are its workflow plugins, skills, agents, and connectors.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

- NVIDIA SkillSpector warn
SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 15 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Excessive Agency · line 29 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.04830 |
| Opus 5 | $0.00032 | $0.02415 |
| Sonnet 5 | $0.00013 | $0.00966 |
| Haiku 4.5 | $0.00006 | $0.00483 |
Grade A, and why
saas-msa-review 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 13d 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.

SaaS / Subscription Agreement Review
Matter context
Matter context. Check ## Matter workspaces in the practice-level CLAUDE.md. If Enabled is ✗ (the default for in-house users), skip the rest of this paragraph — skills use practice-level context and the matter machinery is invisible. If enabled and there is no active matter, ask: "Which matter is this for? Run /commercial-legal:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/claude-for-legal/commercial-legal/matters/<matter-slug>/. Never read another matter's files unless Cross-matter context is on.
Purpose
SaaS agreements have a distinct risk profile from one-time vendor contracts. The dollars compound over renewals, the data accumulates, and the switching cost grows every month. This skill reviews with that in mind.
It runs the standard playbook check from ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md and adds a SaaS-specific overlay on the terms that bite hardest in subscription deals.
Jurisdiction assumption
SaaS terms (auto-renewal notice requirements, price-escalation caps, data-portability mandates, subprocessor rules) are jurisdiction-sensitive — California, New York, and EU rules diverge materially, and some states have auto-renewal statutes that override private contract terms. This review applies the team's positions from ~/.claude/plugins/config/claude-for-legal/commercial-legal/CLAUDE.md, which assume the governing law recorded there. If the agreement picks a different governing law, or the deal spans jurisdictions with statutory overrides (e.g., EU-based users, California consumers), flag it — the analysis may not transfer as written.
No silent supplement. If a research query to the configured legal research tool (Westlaw, or firm platform) returns few or no results for a statutory override that might bear on the deal (auto-renewal statute, data-portability mandate, consumer-protection rule), report what was found and stop. Do NOT fill the gap from web search or model knowledge without asking. Say: "The search returned [N] results from [tool]. Coverage appears thin for [jurisdiction / rule]. Options: (1) broaden the search query, (2) try a different research tool, (3) search the web — results will be tagged
[web search — verify]and should be checked against a primary source before relying, or (4) flag as unverified and stop. Which would you like?" A lawyer decides whether to accept lower-confidence sources.Source attribution. Where the review cites a statute, regulation, or case (e.g., a state auto-renewal law overriding contract terms), tag the citation:
[Westlaw],[statute / regulator site], or the MCP tool name for citations retrieved from a legal research connector;[web search — verify]for web-search citations;[model knowledge — verify]for citations recalled from training data;[user provided]for citations from the counterparty draft or house files. Citations taggedverifycarry higher fabrication risk and should be checked first. Never strip or collapse the tags.
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.

saas-msa-review is a skill published in the GitHub repository anthropics/claude-for-legal (9,433 stars, last pushed 21d ago), licensed Apache-2.0. It adds 65 tokens to every session and 4,830 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
