Knowledge Work Plugins

Plugins that turn Claude into a specialist for your role, team, and company. Built for Claude Cowork, also compatible with Claude Code.

Why Plugins

Cowork lets you set the goal and Claude delivers finished, professional work. Plugins let you go further: tell Claude how you like work done, which tools and data to pull from, how to handle critical workflows, and what slash commands to expose — so your team gets better and more consistent outcomes.

Each plugin bundles the skills, connectors, slash commands, and sub-agents for a specific job function. Out of the box, they give Claude a strong starting point for helping anyone in that role. The real power comes when you customize them for your company — your tools, your terminology, your processes — so Claude works like it was built for your team.

Plugin Marketplace

We're open-sourcing 11 plugins built and inspired by our own work:

Install these directly from Cowork, browse the full collection here on GitHub, or build your own.

Claude Code

Once installed, plugins activate automatically. Skills fire when relevant, and slash commands are available in your session (e.g., /sales:call-prep, /data:write-query).

How Plugins Work

Every plugin follows the same structure:

- Commands are explicit actions you trigger (e.g., /finance:reconciliation, /product-management:write-spec).
- Connectors wire Claude to the external tools your role depends on — CRMs, project trackers, data warehouses, design tools, and more — via MCP servers.

Every component is file-based —…
