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.

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 | $0.05009 |
| Opus 5.5 | $0.00026 | $0.02004 |
| Sonnet 5.5 | $0.00013 | $0.01002 |
| Haiku 4.5 | $0.00006 | $0.00501 |
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 1mo 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.
This is a copy
81% identical to saas-msa-review — 51 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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-hk-law/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-hk-law/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. This review applies the team's positions from ~/.claude/plugins/config/claude-for-hk-law/commercial-legal/CLAUDE.md, which default to Hong Kong (HKSAR), England and Wales, and Singapore governing law unless the profile or contract says otherwise. If the agreement picks a different governing law, or the deal spans jurisdictions with statutory overrides (e.g., US state auto-renewal statutes, EU-based users, PDPO cross-border issues for HK processors), flag it — the analysis may not transfer as written.
No silent supplement. If a research query to the configured legal research tool (HKLII, e-Legislation, Westlaw Asia, 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.
