Accelerate design workflows — critique, design system management, UX writing, accessibility audits, research synthesis, and dev handoff. From exploration to pixel-perfect specs.
Generate developer handoff specs from a design
Run a WCAG accessibility audit on a design or page
Get structured design feedback on usability, hierarchy, and consistency
Audit, document, or extend your design system
Synthesize user research into themes, insights, and recommendations
Audit designs and code for WCAG 2.1 AA compliance. Trigger with "is this accessible", "accessibility check", "WCAG audit", "can screen readers use this", "color contrast", or when the user asks about making designs or code accessible to all users.
Evaluate designs for usability, visual hierarchy, consistency, and adherence to design principles. Trigger with "what do you think of this design", "give me feedback on", "critique this", "review this mockup", or when the user shares a design and asks for opinions.
Create comprehensive developer handoff documentation from designs. Trigger with "handoff to engineering", "developer specs", "implementation notes", "design specs for developers", or when a design needs to be translated into detailed implementation guidance.
Manage design tokens, component libraries, and pattern documentation. Trigger with "design system", "component library", "design tokens", "style guide", or when the user asks about maintaining consistency across designs.
Plan, conduct, and synthesize user research. Trigger with "user research plan", "interview guide", "usability test", "survey design", "research questions", or when the user needs help with any aspect of understanding their users through research.

Plugins that turn Claude into a specialist for your role, team, and company. Built for Claude Cowork, also compatible with Claude Code.
Cowork lets you set the goal and Claude delivers finished, professional work. Plugins let you go further: tell Claude how you like work done, which tools and data to pull from, how to handle critical workflows, and what slash commands to expose — so your team gets better and more consistent outcomes.
Each plugin bundles the skills, connectors, slash commands, and sub-agents for a specific job function. Out of the box, they give Claude a strong starting point for helping anyone in that role. The real power comes when you customize them for your company — your tools, your terminology, your processes — so Claude works like it was built for your team.
We're open-sourcing 11 plugins built and inspired by our own work:
