anthropics/knowledge-work-plugins: Open source repository of plugins primarily intended for knowledge workers to use in Claude Cowork

Open source repository of plugins primarily intended for knowledge workers to use in Claude Cowork - anthropics/knowledge-work-plugins

Summary

anthropics/knowledge-work-plugins is a collection of 11 open-source plugins for Claude Cowork and Claude Code that package domain expertise, slash commands, and external tool connectors for specific knowledge-work roles. Each plugin is a directory of markdown and JSON files with no build step, so engineers can read the source, fork it, and adapt it to internal tool stacks.

What it is useful for

The repo is useful for teams already on Claude Cowork or Claude Code who want role-specific behavior out of the box. Examples documented in the README:

• data — exposes commands like /data:write-query and connects to Snowflake, Databricks, BigQuery, Definite, Hex, and Amplitude.
• enterprise-search — a single query interface across Slack, Notion, Guru, Jira, Asana, and Microsoft 365.
• finance — commands for reconciliation, journal entry prep, variance analysis, and close support, with Snowflake, BigQuery, and Databricks connectors.
• productivity, sales, customer-support, product-management, marketing, legal, bio-research — additional role-specific plugins, each with their own connector lists and slash commands.

Beyond the specific roles, the repo is a reference implementation. Every plugin follows the same structure: .claude-plugin/plugin.json, .mcp.json, a commands/ directory for slash commands, and a skills/ directory of markdown the model draws on automatically. Engineers building internal plugins can copy that structure as a template. The repo is published under the Apache-2.0 license.

How engineers can use it

For Claude Code users, the README documents installation:

claude plugin marketplace add anthropics/knowledge-work-plugins
claude plugin install data@knowledge-work-plugins

After install, skills fire automatically and slash commands become available in the session. For Cowork, the README only points to claude.com/plugins; no CLI steps are given.

To customize, engineers edit the markdown skill files to capture their team's terminology, org structure, and processes, then update .mcp.json to point at internal tools. The cowork-plugin-management plugin is intended specifically for authoring and adapting plugins. The README describes the bundled plugins as "generic starting points" — they are meant to be adapted, not used verbatim. The README does not document local testing workflows, version pinning, or offline behavior, so teams rolling these out across an organization should review the README and upstream docs before treating them as production tooling.
