Contract Review

anthropics/knowledge-work-pluginsOfficial

Reads NDAs, MSAs, and vendor contracts from local files, Gmail attachments, or DocuSign envelopes, then flags non-standard terms across eight risk categories: payment timing, liability caps, termination rights, IP assignment, scope creep protections, non-competes, confidentiality overreach, and operational gotchas like auto-renewal windows. Built for small businesses without in-house legal. Outputs a severity-tiered summary with exact clause quotes, plain English explanations, and a negotiation playbook, then exports a redlined DOCX you can send back. The approval gates are sensible: it quotes actual language instead of paraphrasing, flags what's missing not just what's there, and adjusts recommendations to the power dynamic instead of treating every contract like a peer negotiation.

Contract Review

Where this skill sits

Two standing jobs, neither dependent on any chain:

Standalone review — the owner forwards or uploads any NDA, MSA, lease, or vendor agreement and gets the plain-English risk read and the redline. This is the everyday case for a business with no legal on staff.
The counterparty's paper in a deal — when proposal-builder sends a proposal out and the customer's own contract comes back, this skill is the risk read on that paper before the owner signs. That pairing is the quote-to-cash story's closing beat.

Quick start

Attach a contract file, forward the email containing it, or paste the text directly.

User: "Review this MSA and flag anything I should push back on."
→ Skill reads the document, identifies parties and contract type,
  analyzes 8 risk categories, returns a severity-tiered summary
  with a negotiation playbook, and exports a redlined DOCX.
