Claude for Legal

Reference agents, skills, and data connectors for the legal workflows we see most — in-house commercial, privacy, product, corporate, employment, litigation, regulatory, AI governance, IP, and the learning side of the practice (law school clinics and students).

New here? Start with QUICKSTART.md — install in 60 seconds. This README is the full reference.

Everything here is available two ways from one source: install it as a Claude Cowork or Claude Code plugin, or deploy it through the Claude Managed Agents API behind your own workflow engine. Same system prompt, same skills — you choose where it runs.

[!IMPORTANT] Every output from these plugins is a draft for attorney review — not legal advice, not a legal conclusion, not a substitute for a lawyer. They are built with guardrails that reflect that: source attribution on every citation, conservative defaults on privilege and subjective legal calls, jurisdiction assumptions surfaced, and explicit gates before anything is filed, sent, or relied on. A lawyer reviews, verifies, and takes professional responsibility for anything that leaves the building. These plugins make that review faster; they do not replace it.

These plugins do not represent Anthropic's legal positions. They are tools that help lawyers analyze issues. Where a skill includes a checklist item, a suggested framework, a risk flag, or a characterization of case law or regulatory guidance, that is an aid to the reviewing attorney's own analysis, not a statement of Anthropic's view of the law. The law in many of these areas is unsettled and evolving. The attorney using the plugin — not the plugin, and not Anthropic — is responsible for the legal positions taken in their work product.

What's in the repo:

• Practice-area plugins covering in-house, firm, and academic legal work — each one built around a cold-start interview that learns your playbook and a CLAUDE.md practice profile that every skill reads from.
• Managed-agent cookbooks for the scheduled, eyes-on-the-feed workflows (renewal watcher, docket watcher, regulatory feed monitor, diligence grid, launch radar).
• MCP connectors across general productivity (Slack, Google Drive, Box) and legal-specific systems (Ironclad, DocuSign, iManage, Lexis+, Everlaw, CourtListener, and more).
• Named agents — end-to-end workflow agents (Vendor Agreement Reviewer, DSAR Responder, Termination Reviewer, Claim Chart Builder, …) with job-style names and a single command to run each one.

Agents

Each agent is named for the workflow it runs. They're the most common surface — start with the ones that match your work, then tune the underlying skill, the practice profile, and the connectors to how your team does it.
