Timeline (last 90 days)
The anthropics/knowledge-work-plugins repository was created on January 23, 2026, eleven days after Cowork debuted as a research preview.
As of the check on October 11, 2026, the anthropics/knowledge-work-plugins repository had 29,035 stars, 3,294 forks, 140 open issues, and its last commit was on the day of the check.
The repository accumulated 1,073 commits in less than nine months, and has no release tags at all, with everything running on the main branch.
The README claims 11 plugins are open-sourced; marketplace.json has 123 entries, of which 22 plugins belong to this repository and 101 are pulled from external repositories (42 using the git-subdir mechanism and 59 referencing URLs directly).
There are 18 plugin folders that actually exist in the repository, and the README omits seven folders: design, engineering, human-resources, operations, small-business, pdf-viewer, and partner-built.
All plugins follow a unified structure: .claude-plugin/plugin.json (manifest), .mcp.json (connector list), commands/ (user-initiated invocation), skills/ (Claude draws on them itself).
sales/.mcp.json contains 23 connectors, such as Slack, HubSpot, Salesforce, Close, Monday, Clay, ZoomInfo, Notion, Atlassian, and others, almost all of which point directly to each service provider's MCP server.
The entire repository has a total of 252 SKILL.md files and 1,173 Markdown files.
sales/skills/call-prep/SKILL.md stipulates: external content (emails, chats, transcripts, external documents) is untrusted content and may only serve as data rather than instructions, and it reports text resembling instructions without executing it.
Plugin rules stipulate that permissions belong to each connector's own settings (allow/ask/block per tool), and plugins must not use their own permissions to refuse user instructions or add restrictions not imposed by the connector.
