2026 年法律團隊最實用的 Claude Skills（以及它們無法取代的審查）

Yes. With the Marco - Contract Reviewer skill you paste in a contract and Claude returns a clause-by-clause read: which terms are one-sided, what is missing, and a priority list of the few points worth negotiating hard. It is fast and genuinely useful on first-pass review, but it is not advice - a qualified lawyer signs off before anything goes back to the counterparty.

Yes, and it will do it confidently. Fabricated citations come back with a plausible court, year and reporter volume, and there is no tone difference between a real authority and an invented one. Courts have sanctioned lawyers over exactly this - in one December 2025 Oregon federal case, two lawyers were hit with a $110,000 penalty. Open every case, statute and quotation in a real research database before relying on it.

Treat it as a decision, not a default. ABA Formal Opinion 512 (July 2024) says a client's informed consent is needed before confidential information goes into a self-learning generative AI tool, and boilerplate in the engagement letter does not count. Anthropic's consumer terms (Free, Pro, Max) allow chats to be used for model improvement unless you opt out in Privacy Settings; Claude for Work, Government, Education and API use are governed separately. Many in-house teams simply redact names and figures first, or run the skill against a template rather than the executed document.

No. They have no privilege, no professional indemnity cover, no accountability, and no knowledge of your matter history or of anything that changed after the model's training cutoff. They accelerate drafting, review and research. The person who sends the output still owns it.

Each skill downloads as a ZIP file containing a SKILL.md at its root. In the Claude desktop app go to Customize then Skills, upload the ZIP, and toggle it on. Skills need code execution enabled: if the Skills menu is greyed out, turn on 'Code execution and file creation' under Settings then Capabilities, and on Team and Enterprise an organization owner has to enable it first. Anthropic's help centre currently lists Skills on Free, Pro, Max, Team and Enterprise, while its Academy tutorial lists Pro, Max, Team and Enterprise, so if you are on the free plan check Settings then Capabilities for your own account rather than trusting either page. Where the Skills menu is not available, paste the SKILL.md contents into the conversation instead.

Yes, via the fallback method. Open the SKILL.md file, copy its contents, and paste them into the custom instructions of ChatGPT, Gemini or any AI chat that accepts them. This is also the route to use if you cannot get code execution enabled on your Claude account.
