GitHub - anthropics/knowledge-work-plugins: Open source repository of plugins primarily intended for knowledge workers to use in Claude Cowork
Short summary
Anthropic has released 11 open-source plugins that turn Claude into a specialist for roles like sales, legal, finance, and product management. Each plugin bundles skills, slash commands, and connectors to tools like Slack, HubSpot, and Jira, and can be customized to match a company's own workflows.
- Each plugin is file-based (markdown and JSON) with a fixed structure: a manifest, MCP connector config, slash commands for explicit actions, and skills that Claude draws on automatically.
- Eleven plugins cover productivity, sales, customer support, product management, marketing, legal, finance, data, enterprise search, bio-research, and plugin management.
- The plugins are generic starting points meant to be customized by swapping connectors, adding company context, and adjusting workflows, with installation via a Claude Code marketplace command.
Full summary
Anthropic has open-sourced 11 plugins on GitHub for Claude Cowork, which also works with Claude Code. Each plugin is a folder of markdown and JSON files bundling skills (domain know-how Claude pulls in automatically), slash commands you trigger yourself, and connectors that link Claude to outside tools through MCP servers. There's no code to run and no build step. The plugins cover productivity, sales, customer support, product management, marketing, legal, finance, data, enterprise search, bio research, and a meta-plugin for creating or customizing other plugins. Install is a two-line affair: add the marketplace with `claude plugin marketplace add anthropics/knowledge-work-plugins`, then install a specific one such as `sales@knowledge-work-plugins`. Commands look like `/sales:call-prep` or `/data:write-query`.
The connector lists show what each plugin expects to talk to. The sales plugin wants HubSpot, Close, Clay, ZoomInfo and Fireflies; finance wants Snowflake, Databricks and BigQuery; legal wants Box and Egnyte alongside Microsoft 365. The bio-research plugin is the outlier, wired to PubMed, bioRxiv, ClinicalTrials.gov, ChEMBL, Benchling and similar scientific databases. Most of the others assume a common core of Slack, Jira, Notion and Microsoft 365, so if your company runs a different stack you'll be editing `.mcp.json` before anything useful happens.
The authors are clear that the plugins are generic starting points and that the value comes from customization. You swap in your own connectors, drop company terminology and org structure into skill files, and rewrite workflow instructions to match how your team really operates. The `cowork-plugin-management` plugin is meant to help with building new ones for roles not yet covered. The repo accepts contributions through pull requests, since the whole thing is plain files a team can fork and adapt.
