Feature Implementation Workflow

PROSE constraints: Orchestrated Composition (chains phases into a complete workflow) + Safety Boundaries (validation gates between phases).

Phase 1: Context Loading

1. If $ARGUMENTS points to a spec file, read it
2. Review existing codebase patterns in the affected area
3. Check relevant .claude/rules/ for applicable standards
4. Identify affected components, routes, types, and tests

Phase 2: Planning

Before writing any code, produce a brief implementation plan:
