vendor-agreement-review

vendor-agreement-review is a skill for Claude Code from uk-agents/uk-legal-plugins. It costs 106 tokens per session (5,019 once invoked), scanned A, original, Apache-2.0.

A contract-review process for an agreement from a vendor or supplier. It compares the document with the team’s legal playbook, identifies differences, assesses risk, and drafts specific redline wording—suggested edits to the contract.

In plain words
What is it for?
Reviewing supplier contracts, flagging deviations, assessing their risk, preparing negotiation edits, and saving matter-specific outputs when matter workspaces are enabled.
Why use it?
It helps a legal team find non-standard terms and respond with concrete changes instead of reviewing the agreement without a consistent reference point.

Token cost

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.

Security

Grade A, and why

vendor-agreement-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 12d 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.

Vendor 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 for matter-specific context and overrides. Write outputs to the matter folder at ~/.claude/plugins/config/uk-legal-plugins/commercial-legal-uk/matters/<matter-slug>/.


Destination check

Before producing output, check where it's going. If the user has named a destination (a channel, a distribution list, a counterparty, "everyone"), ask whether it's inside the privilege circle. Public channels, company-wide lists, counterparty/opposing counsel, vendors, and clients (for work product) waive the protection. When the destination looks outside the circle, flag it and offer (a) the privileged version for legal only, (b) a sanitized version for the broader channel, or (c) both. See the canonical ## Shared guardrails → Destination check in this plugin's CLAUDE.md.

Purpose

Read a vendor agreement against the playbook this team actually uses (in ~/.claude/plugins/config/uk-legal-plugins/commercial-legal-uk/CLAUDE.md), find every term that deviates, and tell the solicitor what to do about each one — with specific redline language, not vague "consider revising."

This review applies English contract law as the default. Where the contract's governing law is Scots law or Northern Ireland law, the review notes applicable differences. Where the contract involves EU or other foreign law, the review flags cross-border issues.

The output is a review memo the solicitor can act on in one pass. Every issue has a severity, a business-impact explanation, a proposed fix, and an escalation call if one is needed.

Precondition: load the playbook

Before reading the contract, read ~/.claude/plugins/config/uk-legal-plugins/commercial-legal-uk/CLAUDE.md. If it's missing or still has placeholders, surface this bounce:

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.
