Claude Cowork Plugins: The Complete Guide

Claude Cowork is Anthropic's collaborative workspace product, designed for teams that want to work alongside Claude in a shared, persistent environment. Unlike Claude Code — which operates in your terminal as a CLI tool — Cowork provides a visual, project-based interface where multiple team members can interact with Claude simultaneously.

For teams already using Cowork, plugins transform Claude from a general-purpose assistant into a domain specialist. Finance teams get institutional-grade modeling. Marketing teams get competitive analysis frameworks. Development teams get structured engineering methodology. All within the collaborative environment your team already uses.

How Cowork Plugins Differ from Claude Code Plugins

While the capabilities are identical, the technical format is different. Claude Code plugins live inside a .claude/skills/ directory structure, designed for CLI environments. Cowork plugins use a different architecture: a .claude-plugin/plugin.json manifest at the root, with all capabilities organized as flat files alongside dedicated agents and hooks.

The same ZIP does not work for both formats. That is why every Leopoldo plugin ships in two versions — one for Claude Code, one for Cowork. When you purchase any plugin, you get both. Buy once, use anywhere.

Installation in Cowork

Setting up a Cowork plugin takes under two minutes:

1. Download your Cowork-format ZIP from your Leopoldo dashboard
2. Extract it into your Cowork project directory
3. The .claude-plugin/plugin.json manifest tells Cowork what capabilities are available
4. Run /setup and enter your license key
5. Claude now has access to the full plugin — agents, orchestrators, and hooks included

That is it. No configuration files to edit, no environment variables to set. The plugin manifest handles discovery automatically.

Why Cowork Plus Plugins Changes Everything for Teams

Cowork on its own gives your team a shared AI workspace. Plugins give that workspace genuine expertise. The combination means your team gets a specialist that is always available, always consistent, and always following your methodology.

Consider a finance team using the Deal Engine plugin in Cowork. Every analyst on the team has access to the same deal screening methodology, the same due diligence frameworks, the same output structures. There is no drift between how one analyst uses Claude and how another does. The plugin enforces consistency.

The Complete Kit

Every Leopoldo plugin is more than a collection of prompts. Each one is a complete kit containing agents that manage complex multi-step workflows, orchestrators that coordinate between different analytical processes, and hooks that enforce quality gates before any output reaches you. This architecture works identically in both Claude Code and Cowork.

Auto-Updates Keep Your Team Current

Leopoldo builds, tests, and updates plugins autonomously. Every plugin includes 12 months of live updates. When a new version is released, your Cowork installation detects it automatically at session start, downloads the update, and installs it silently. Your team always has the latest methodology without anyone lifting a finger.
