Claude Litigation-Legal Plugin
Install + run Anthropic's litigation-legal plugin: 14 skills covering matter intake, portfolio status, legal holds, chronology, claim charts, demand letters, subpoena triage. Defensible under Couvrette + Heppner. 8 lessons + certificate.
Anthropic shipped a litigation plugin in May 2026, and most lawyers don’t know what’s in it
On May 12, 2026, Anthropic released Claude for Legal — twelve practice-area plugins for litigation, transactional, regulatory, privacy, IP, and other vertical work, plus sixteen MCP connectors to CourtListener, Trellis, iManage, NetDocuments, Everlaw, and others. The plugins were open-sourced on GitHub. Most lawyers heard the headline. Most lawyers stopped there.
This course is the deep walk of one of those plugins — litigation-legal/ — for the people who actually have to use it. Fourteen named skills covering matter intake, portfolio rollup, legal-hold notices, chronologies, claim charts, demand letters, subpoena triage, and outside-counsel status updates. A data architecture (_log.yaml as your portfolio ledger; per-matter folders as the source of truth) that you can defend under the Heppner privilege framework. Three universal markers ([CITE:], [VERIFY:], [SME VERIFY:]) that document supervision under Rules 5.1 / 5.3 every time the plugin produces output.
You’ll come out the other end with a fully configured CLAUDE.md cold-start profile, a sample portfolio of 3-5 matters loaded into the plugin’s data model, a written verification rail applied to every output, and a credential (CLP-XXXXXX) that documents the work. The plugin itself costs nothing beyond your Claude Pro subscription. The discipline this course teaches you to wrap around it is the difference between a tool that saves you ten hours a week and a tool that lands your name on the Damien Charlotin sanctions database.

Frequently Asked Questions
Do I need Claude Code or Claude Cowork specifically — does the free Claude.ai web tier work?
The plugin requires Claude Cowork (Mac/Windows app) or Claude Code (CLI) — it installs as a plugin from Anthropic's marketplace. The free web tier doesn't support plugin installation. The Claude Pro tier ($20/mo) includes Cowork access.
Is the data the plugin generates safe under the Heppner privilege ruling (SDNY Feb 2026)?
Yes, with the right architecture. Claude Cowork at the Pro / Team / Enterprise tier with negotiated data-protection terms passes the Heppner Rule 1.6 analysis. The plugin's own file architecture stores data on your local machine, not Anthropic's servers. Lesson 3 walks the architecture in detail.
Does this replace Filevine / Onit / Streamline / Xakia matter management?
Partially. The plugin covers matter intake, portfolio status, legal holds, chronologies, claim charts, and demand letters — the litigation core. It does not replace billing, conflict checking, or full document management. Lesson 7 covers the hybrid workflow where the plugin sits alongside existing systems.
How does this work with the existing FindSkill.ai course catalog?
It's a deep dive on one of Anthropic's 12 practice-area plugins (Claude for Legal). It assumes you've completed The Hallucination Defense Playbook (verification protocol) and pairs with AI for Paralegals (Rule 5.3 supervision).
