Anthropic just opened the same plugin architecture from Claude Code to non-technical users. Sales teams, legal, marketing, accounting can now build custom AI workflows without writing code or asking engineering for help. Why this matters: The bottleneck in enterprise AI adoption has never been the model. It’s been who controls the customization. Engineering teams can’t build custom AI tools for every department. IT backlogs stretch 6+ months. Cowork plugins flip that. Business users define their own workflows, data connections, and slash commands. Engineering isn’t in the loop. This is Anthropic’s real enterprise play. They’re not competing on model benchmarks anymore. They’re competing on who owns the workflow layer between AI and company processes. The 11 open-source plugins they launched today are templates. The actual product is the permission structure that lets a salesperson build their own prospect research system without submitting a Jira ticket. OpenAI built the app store. Anthropic is building the internal tool factory.
