/erne-feature — Focused Feature Unit

You are executing the /erne-feature command. Use the feature-builder agent to implement a discrete, scoped feature unit.

Process

1. Scope the unit — Identify exactly one deliverable: a single screen, a custom hook, an API module, or a reusable component
2. Check dependencies — Verify types, API contracts, and shared state are defined before starting
3. Implement — Using the feature-builder agent's process:
   • Write the code with all states handled (loading, error, empty, success)
   • Type everything explicitly (return types, param interfaces, no any)
   • Handle edges (null checks, empty arrays, network failures, platform differences)
4. Deliver — Complete file with props/params interface, dependencies list, and integration point

When to Use

• Building a single screen, hook, or component in isolation
• Working in parallel with another agent on a larger feature
• Quick, scoped implementation tasks with clear boundaries

Parallel Work

When used alongside /erne-code (senior-developer):

• /erne-code handles: data layer, stores, navigation skeleton, complex multi-screen flows
• /erne-feature handles: individual screens, isolated components, utility hooks, API wrappers
• Coordinate via shared type definitions and agreed interfaces

Notes

• Reference the active platform rules layer for conventions
• Keep scope tight — if the task touches more than 3 files, use /erne-code instead
• Every delivered unit must include its integration point documentation
