How to Use Claude for Legal Workflow: The Cass Skill Guide

Most of the legal work that eats a team’s week is not clever lawyering — it is workflow. Intake forms, chasing signatures, summarising a contract for someone who will not read it, keeping track of which NDA is with whom, turning a request into a clean brief for counsel. Using Claude for legal workflow means handing that repetitive layer to a tool like Claude, ChatGPT, or any AI chat, so the expensive human judgement is spent on the things that actually need it. This is operational help, not legal advice — anything with legal consequence still goes to a qualified solicitor.

Here are the jobs the skill takes off your plate.

Triage and intake

Legal teams drown in vague requests. The skill turns “can you look at this?” into a structured intake: what kind of matter it is, what is being asked, the deadline, the risk level, and what is missing before anyone can act. A clean intake means the right requests reach the right person without three rounds of email.

Reading the long thing so you can act on it

Someone sends a forty-page agreement and needs the gist by lunch. The skill produces a plain summary — what it is, the key obligations, the dates that bite, the clauses worth a closer look — so a non-lawyer understands the shape of it and a lawyer knows where to focus. For a deeper read of a specific contract, our contract review guide goes clause by clause.

Drafting from your templates

Routine documents do not need to be written from scratch each time. Give the skill your standard template and the specifics, and it produces a first draft — the NDA, the engagement letter, the standard terms — with the variables filled and the bits needing a human decision clearly flagged. You review and approve rather than retype.

Tracking who has what

Half of legal admin is memory: which version is current, who still owes a signature, when a renewal lands. The skill helps you build and maintain that tracker — a status view of every matter and document — so nothing falls through the cracks because it lived only in someone’s inbox.

Briefing counsel properly

External lawyers are expensive partly because clients brief them badly. The skill packages a matter into a tight brief — the facts, the question, what has been tried, what you actually need — so you buy answers, not hours of someone untangling your email thread. The same instinct as a legal assistant, applied to the flow of work rather than a single task.

Why a skill beats a one-off prompt

Legal workflow is repetitive by nature, which is exactly where a loaded skill pays off: it holds your intake format, your templates, and your tracking logic, so every matter is handled the same disciplined way instead of being reinvented. Consistency is half of what good legal ops actually means.

The boundary that matters most

This skill organises and drafts; it does not advise, and it must not be the final word on anything with legal weight. It can be confidently wrong about the law, and it does not know your jurisdiction unless you tell it — and even then, a qualified solicitor signs off on the substance. Used as the operations layer beneath your legal team, using Claude for legal workflow gives the humans their week back for the judgement only they can provide.
