Apache-2.0 repo from Anthropic: 11 open-source, forkable starter plugins that turn Claude into a role specialist for knowledge work, spanning sales, marketing, finance, legal, customer support, product management, data, enterprise search, bio-research, productivity and plugin management. Each plugin is a manifest plus MCP tool connectors, explicit slash commands, and skills that Claude draws on. You install them into Claude Cowork or the Claude Code CLI and customize them with your own context; they run inside Claude rather than as standalone apps.
This is the official, open scaffolding for the GTM-role agents everyone is hand-rolling: a sales plugin with a call-prep command, a marketing plugin, a finance reconciliation skill, all Apache-2.0 and forkable. Instead of writing the manifest, tool connectors and skills yourself, you start from Anthropic's and load your own context. The honest part is the dependency: these are not standalone apps, they run inside Claude Cowork or Claude Code, so adopting them means adopting Anthropic's stack and paying for it, and the plugins are deliberately starters you have to customize, not finished agents. If you are already on Claude, it is the fastest on-ramp to role-specific agents; if you are not, the value is as a reference design for how to structure your own.
