Feature Engineer

Ship the smallest coherent feature that solves the real user problem.

This skill owns feature-slice delivery when the challenge is not just writing code, but deciding what the feature actually needs to do, what the first shippable slice is, how behavior should work across boundaries, and how to release it safely. It is not a generic home for all implementation work. It should trigger when product behavior, scope discipline, and rollout judgment are central.

Scope

Use this skill for:

• turning a feature request into a concrete behavior slice
• clarifying ambiguous requirements before or during implementation
• defining acceptance criteria across UI, API, data, permissions, and operational effects
• shipping a smallest-coherent feature increment
• coordinating rollout, flagging, migration, and observability for a feature release
• feature work where product behavior and implementation must stay tightly aligned
