仕組み

  1. Clarify your goal

    Choose the practice-area plugins that match your work (for example commercial, privacy or corporate) and be ready to complete each plugin's setup interview.

  2. Get the project

    Clone anthropics/claude-for-legal from GitHub (or use the install path in the run steps below) and skim its README for the parts relevant to your goal.

  3. Install and configure

    Add this repository as a Claude plugin marketplace, install the plugins you need, then restart Claude Code or open Cowork.

  4. Run your first task

    Run setup for an installed plugin to write your practice profile, then invoke one of its named agents on a real matter, such as a vendor agreement review.

// 機能

選ばれる理由

Practice-area plugins

Plugins covering in-house, firm and academic legal work, each built around a cold-start interview and a persistent CLAUDE.md practice profile.

Named workflow agents

End-to-end agents with job-style names — Vendor Agreement Reviewer, DSAR Responder, Termination Reviewer, Claim Chart Builder and more — each run with a single command.

Managed-agent cookbooks

Recipes for scheduled, eyes-on-the-feed workflows: renewal watcher, docket watcher, regulatory feed monitor, diligence grid and launch radar.

MCP connectors

Connectors across general productivity (Slack, Google Drive, Box) and legal-specific systems (Ironclad, DocuSign, iManage, Everlaw, CourtListener and more).

Editable practice profile

Your playbook, escalation rules and house style live in a plain-English CLAUDE.md you can edit directly; it survives plugin updates.

Community skill trust layer

Community legal skills get a security review — hidden-content scan, injection detection and a structural trust check — on every install.

よくある質問

Who maintains claude-for-legal?

Anthropic, through the anthropics/claude-for-legal repository; some external plugins under external_plugins/ are maintained by their vendors.

Is claude-for-legal free to use?

Yes — the project is open source under the Apache-2.0 license as recorded for this listing. See the license terms for any conditions on redistribution.

Does claude-for-legal need a paid API key?

It runs inside Claude Cowork / Claude Code, so you need your own Claude access; the plugins themselves are free and Apache-2.0 licensed.

How does this compare to prompting a general AI assistant for legal work?

A general assistant starts from zero each time. These plugins persist your playbook in a practice profile, ship named agents for whole workflows, and connect to legal systems via MCP — but they assist lawyers rather than replacing legal judgment.

How do I get started with claude-for-legal?

Clone the repository (or use the documented installer), follow the install and configure steps on this page, and run the smallest real task first — run setup for an installed plugin to write your practice profile, then invoke one of its named agents on a real matter, such as a vendor agreement review.
