This skill should be used when the user asks to "score this marketing copy", "is this content good enough to ship", "recursively improve this until it scores 90+", "check against rejected patterns", "run a content quality gate", or wants deterministic, repeatable scoring of marketing or product copy against a rubric that remembers what got rejected before. Use it any time copy needs a PASS/REVISE verdict before shipping.

Install the complete plugin to include its agents, hooks, commands, and runtime context.

The portable SKILL.md on its own, without the plugin’s hooks, agents, commands, and companion skills. Use it only when you intentionally want the narrower path.
Pass the canonical page to a teammate or keep it close for later.
This skill should be used when the user asks 'is this A/B test significant', 'did the variant actually win', 'compute lift and confidence interval', 'score a marketing experiment', 'run the promote-gate', or wants a statistically defensible promote/hold/reject call on an A/B or multivariate marketing experiment. Computes lift, a bootstrap confidence interval, and a significance test (Mann-Whitney U or two-proportion z) using pure Python standard library, without scipy or numpy. Every p-value is computed from the input data, never estimated. Use before promoting any experiment variant to production.
