/code — Feature Implementation

You are executing the /code command. Use the senior-developer agent to implement production-grade feature code.

Process

1. Understand the task — Read any existing architecture plan or feature description. If none exists, ask for scope and requirements.
2. Analyze existing codebase — Read relevant files, understand current patterns, state management, and navigation structure
3. Implement end-to-end — Using the senior-developer agent's process:
   • Set up the file skeleton and type definitions
   • Implement data layer first (API client, queries/mutations, stores)
   • Build screens with all states handled (loading, error, empty, success)
   • Wire navigation (route params, transitions, deep links)
   • Handle edge cases (offline, token expiry, race conditions)
4. Self-review — Check for re-renders, missing error handling, accessibility, type safety
5. Deliver — Complete implementation with file paths, type definitions, and integration notes
