figma-design-sync
Use this agent when you need to synchronize a web implementation with its Figma design by automatically detecting and fixing visual differences. This agent should be used iteratively until the implementation matches the design.\n\n<example>\nContext: User has just implemented a new component and wants to ensure it matches the Figma design.\nuser: \"I've just finished implementing the hero section component. Can you check if it matches the Figma design at https://figma.com/file/abc123/design?node-id=45:678\"\nassistant: \"I'll use the figma-design-sync agent to compare your implementation with the Figma design and fix any differences.\"\n<uses Task tool to launch figma-design-sync agent with the Figma URL and local URL>\n</example>\n\n<example>\nContext: User is working on responsive design and wants to verify mobile breakpoint matches design.\nuser: \"The mobile view doesn't look quite right. Here's the Figma: https://figma.com/file/xyz789/mobile?node-id=12:34\"\nassistant: \"Let me use the figma-design-sy...

design-implementation-reviewer
Use this agent when you need to verify that a UI implementation matches its Figma design specifications. This agent should be called after code has been written to implement a design, particularly after HTML/CSS/React components have been created or modified. The agent will visually compare the live implementation against the Figma design and provide detailed feedback on discrepancies.\n\nExamples:\n- <example>\n Context: The user has just implemented a new component based on a Figma design.\n user: "I've finished implementing the hero section based on the Figma design"\n assistant: "I'll review how well your implementation matches the Figma design."\n <commentary>\n Since UI implementation has been completed, use the design-implementation-reviewer agent to compare the live version with Figma.\n </commentary>\n </example>\n- <example>\n Context: After the general code agent has implemented design changes.\n user: "Update the button styles to match the new design system"\n assistant: "I've updated the butto...
