About
A Claude plugin that helps maintain consistent UI design decisions across coding sessions. It automatically saves and loads design patterns like spacing, colors, and component styles to prevent design drift when building interfaces.
What it does
Interface Design gives coding agents a structured design process for product interfaces. It establishes user intent, explores the product domain, proposes a visual direction, and applies explicit choices for hierarchy, typography, color, surfaces, states, motion, and reusable patterns. Separate review modes can critique overall craft or make focused visual cleanups.
Why it's ranked here
This is a strong choice for teams building dashboards, admin tools, and SaaS products with coding agents. Its guidance goes beyond token consistency: it demands a focal point, domain-specific visual language, complete interaction states, accessible primitives, and deliberate composition. The repository also supports both Claude Code and Codex, with direct and natural-language invocation.
What's good
The guidance turns subjective design criticism into concrete checks. It distinguishes hierarchy from mere alignment, asks reviewers to inspect rendered output before individual styles, and filters personal taste from actionable defects. The focused cleanup mode preserves behavior and limits changes to the active diff, while the deeper review mode separates findings from implementation unless fixes are requested.
Tradeoffs
The tool is instruction-driven rather than a runtime design system, so results still depend on the coding agent, available rendering tools, and project context. Its strict craft standards may require user confirmation and several passes. Marketing sites, landing pages, campaigns, and brand-only work are explicitly outside scope. Image-based direction work also requires a separate image-generation capability.
How to use it well
Use it when an agent is building or refining a product interface across multiple sessions. Establish the intended person, task, and feel early, confirm the proposed direction, then preserve approved tokens and component patterns for later work. Choose the focused cleanup pass for narrow branch changes and the deeper review for holistic critique. Pair it with separate marketing design and image-generation tools when those needs arise.
Technical notes+
The core instructions live in .claude/skills/interface-design/SKILL.md, with Codex discovery metadata in .claude/skills/interface-design/agents/openai.yaml. Claude-specific review surfaces are defined by .claude/commands/design-review.md and .claude/commands/design-deslop.md. Plugin metadata and command or skill locations are declared in .claude-plugin/plugin.json, while .claude-plugin/marketplace.json provides marketplace packaging. reference/system-template.md defines the persisted design-system structure, and reference/examples/system-precision.md plus reference/examples/system-warmth.md supply concrete variants. Installation uses the skills CLI, Claude Code marketplace flow, or manual folder copying.
