+Dispatch specialized subagents via the Agent tool for focused work outside your main design work.

+| Subagent | Model | When to use |
+|----------|-------|-------------|
+| `Explore` | Haiku (fast) | Find current UI patterns, component library, existing page layouts, Radix Themes usage |
+| `feature-dev:code-explorer` | Sonnet | Understand how existing interactions are implemented before proposing new patterns |

+Agent(subagent_type="Explore", prompt="Find all modal components, form patterns, and page layouts in cofee_frontend/src/. Map which Radix Themes components are used and how. Thoroughness: very thorough")

+Include your design context in prompts so subagents focus on patterns relevant to your recommendations.
