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 | $0.00083 | $0.03883 |
| Opus 5.5 | $0.00033 | $0.01553 |
| Sonnet 5.5 | $0.00017 | $0.00777 |
| Haiku 4.5 | $0.00008 | $0.00388 |
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.
How it starts
The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SaaS / Subscription Agreement Review (UK)
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. If enabled and there is no active matter, ask: "Which matter is this for? Run /commercial-legal-uk:matter-workspace switch <slug> or say practice-level." Load the active matter's matter.md. 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 pounds 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/uk-legal-plugins/commercial-legal-uk/CLAUDE.md and adds a SaaS-specific overlay on the terms that bite hardest in subscription deals.
UK Legal Framework
This skill applies English contract law as the default. Where the contract's governing law is Scots law or NI law, it notes applicable differences.
Key UK-specific SaaS considerations:
- Auto-renewal: No general UK statute specifically regulating B2B auto-renewal (unlike some US states). English law allows auto-renewal if clear — but consider Consumer Rights Act 2015 if any B2C element; CMA guidance on subscription traps for consumers.
[model knowledge — verify] - Price escalation: No statutory cap in B2B SaaS — market practice. CPI/RPI-linked escalators are common. Check basis (CPI vs. RPI — RPI typically runs higher).
[model knowledge — verify] - Data portability: UK GDPR Article 20 gives individuals a data portability right (not a business right). Contractual portability clauses are what protect the business on exit.
[model knowledge — verify] - UCTA 1977: Service credits as sole remedy for SLA breach — check reasonableness if this purports to exclude liability for negligence causing other loss.
[model knowledge — verify] - UK GDPR / DPA 2018: Sub-processor regime, Article 28 clauses, IDTA / UK Addendum for international transfers, 72-hour breach notification.
[model knowledge — verify]
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 uk-agents/uk-legal-plugins (14 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 83 tokens to every session and 3,883 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
