What It Does
knowledge-work-plugins is Anthropic's official open-source repository of role-specific plugins for Claude Cowork and Claude Code. Each plugin bundles domain skills, MCP server connectors, and slash commands for a specific job function — covering sales, finance, engineering, data, bio-research, and now legal. The entire system is file-based markdown + JSON, so there are no build steps and no infrastructure to run.
Why It's Blowing Up
On May 12, 2026, Anthropic launched "Claude for Legal" — the most coordinated AI push into the legal market since Harvey AI emerged. The release packaged 12 practice-area plugins Commercial, Corporate, M&A, Employment, Privacy, Product, Regulatory, AI Governance, IP, and Litigation Legal alongside 22+ new MCP connectors, wiring Claude into the tools legal teams already use: Ironclad and DocuSign for contracts, Relativity and Everlaw for e-discovery, iManage and NetDocuments for document management, and Midpage, Trellis, and Legal Data Hunter 31M+ documents, 160+ jurisdictions for legal research.
The legal drop was the headline event, but it's part of a broader pattern: the repo has grown from 11 plugins at launch in January 2026 to over 20, now spanning engineering, HR, design, small business, operations, and bio-research. Legal attracted the most coverage because, unlike productivity or sales tools, legal AI directly touches liability — and established players like Harvey, Relativity, and Thomson Reuters responded by integrating rather than competing.
