feature-flag-management

Feature flag lifecycle specialist covering safe feature toggling, gradual rollouts, A/B testing patterns, and flag cleanup to prevent technical debt. Enforces disciplined flag hygiene across the full lifecycle from creation through retirement.

Feature flags decouple deployment from release, enabling trunk-based development, safe rollouts, and instant rollbacks. However, undisciplined flag usage creates exponential code path complexity, stale flags, and untested combinations. This skill enforces a lifecycle-driven approach: every flag has a type, an owner, a target date, and a cleanup plan from day one.
