Claude, Contract Review.

People often type it as a question: is Claude my contract's lawyer? The video answers no. What runs when you hand Claude a contract through a review skill is closer to a checklist, the same steps every time. The more useful question is what that checklist catches and what it misses.

The natural guess

The natural assumption is that Claude reads a contract the way a lawyer would, weighing the whole document clause by clause and case by case. The video sets this up as the common expectation before taking it apart. Between the contract and the review sits a written file, SKILL.md, and that file shapes everything that follows.

A skill is a folder, not a judgment call

A skill is a folder Claude reads before it acts. SKILL.md is the whole instruction set, written in plain language with no hidden logic. The pipeline is fixed: read the file, execute each step in order, and return the result. It is linear, with no branching unless a step says so.

The video draws the consequence directly. This is not judgment, it is a checklist written in advance. The trade-off is that it buys repeatable results, so the same input gets the same output on every run.

The freelance contract example

To make this concrete, the video runs a freelance contract through the skill. The termination clause comes back flagged. The checklist says to look there, so it looks.

The checklist, however, only names what it names. The video's example is an arbitration clause that the list never mentions. That clause gets no comment, and the reason is not that it is fine. It is simply off the list.

What a flag and a clean pass mean

Run the same contract again and the termination flag comes back identical. The video calls that consistency. A flag means a listed check matched, which is not a verdict on the contract.

The same logic applies in the other direction. A clean pass is not a clean bill of health. It means nothing on the list tripped. Whatever is off the list stays invisible either way, whether the result is a flag or a pass.

Key takeaways

• Claude with a review skill behaves like a contract checklist, not a contract lawyer.
• A skill is a folder, and SKILL.md holds the full instructions in plain language.
• The pipeline is read the file, execute each step in order, return the result.
• A fixed checklist trades judgment for repeatable results.
• A flag means a listed check matched, not that the contract is good or bad.
• A clean pass means nothing on the list tripped, and nothing more.
• Clauses the checklist never mentions, such as arbitration in the example, get no comment.
• The read-through of the contract is still the reader's job.

Try it yourself

Paste the video's prompt into Claude along with any contract you are reviewing: ask it to list exactly what it will check for and what it will not, and only then do the review. That first list turns an invisible checklist into one you can see, so you know what the review can and cannot cover before you rely on it. The skill's code is in the humanitarians-youtube repository.
