retention-analysis
by SkeneTechnologies
When the user wants to analyze, diagnose, or improve user retention -- including cohort analysis, churn prediction, engagement scoring, or resurrection campaigns. Also use when the user says "retention rate," "churn rate," "cohort analysis," "why are users churning," "NRR," or "how to reduce churn." For engagement loops, see engagement-loops. For activation, see activation-metrics.

pricing-strategy
by SkeneTechnologies
When the user wants to design or optimize pricing, packaging, or monetization -- including tier structure, freemium design, value metrics, or price research. Also use when the user says "pricing page," "how to price," "freemium vs free trial," "Good-Better-Best tiers," or "value-based pricing." For feature gating, see feature-gating. For trial optimization, see trial-optimization. For usage-based models, see usage-based-pricing.

When the user wants to design or implement usage-based, consumption, or metered pricing -- including credit systems, overage handling, or billing infrastructure. Also use when the user says "pay per use," "metered billing," "credit system," "usage pricing," or "consumption pricing." For broader pricing strategy, see pricing-strategy. For expansion, see expansion-revenue.

Security Auditing Skill
by martinholovsky
If it's not logged, it didn't happen. If logs can be tampered, you can't prove anything.
release-manager
