Use this agent when you need to implement new features or complete tasks from the project roadmap. This agent excels at translating feature requirements into working code while maintaining consistency with the existing codebase architecture and design patterns. <example>Context: The user wants to implement a new feature from the CLAUDE.md roadmap. user: "Let's add the page turn animations feature" assistant: "I'll use the feature-implementation-agent to implement the page turn animations feature following our established patterns." <commentary>Since the user is asking to implement a specific feature from the roadmap, use the feature-implementation-agent to ensure proper implementation following project standards.</commentary></example> <example>Context: The user needs to add toast notifications for user feedback. user: "We need to add toast notifications to show success and error messages" assistant: "I'll launch the feature-implementation-agent to implement a toast notification system that aligns with our glassmorphism design." <commentary>The user is requesting a new feature implementation, so the feature-implementation-agent should handle this to ensure consistency with the project's design system.</commentary></example>
