Can I use this for A/B testing?

Yes, the skill provides guidance on comparing two different implementations and measuring their specific impact on user behavior or system performance.

What rollout strategies are included?

It covers percentage-based rollouts, canary users (beta testers), and audience segmentation by region or user type.

What is the primary benefit of feature flag design?

It allows teams to decouple deployments from releases, enabling safer rollouts and the ability to instantly disable problematic features without a full rollback.

How does this skill help manage technical debt?

It enforces best practices like setting flag owners and expiration dates, ensuring that temporary flags are cleaned up after a successful rollout.

How do I prevent 'flag bloat'?

The skill teaches you to avoid permanent flags, monitor flag usage, and implement a strict cleanup schedule once a feature is fully released.
