Does it help with tracking feature performance?

Yes, it helps define both leading indicators like adoption and activation rates, and lagging indicators like long-term retention and revenue impact.

Can I use this for agile user stories?

Yes, the skill follows the standard 'As a [user], I want [capability] so that [benefit]' format and adheres to INVEST principles (Independent, Negotiable, Valuable, Estimable, Small, Testable).

How does it handle acceptance criteria?

It supports both the BDD-style Given/When/Then format and clear checklists to ensure features are testable, unambiguous, and cover edge cases.

What prioritization framework does this skill use?

It primarily utilizes the MoSCoW framework to categorize requirements into Must-have (P0), Should-have (P1), Could-have, and Won't-have (P2/Future) tiers.
