writing-plans (obra/superpowers)

25.3 / 30

RecommendedSafe

writing-plans: turns a short feature spec into a step-by-step TDD plan (control 1.6, skill 4.4, one-liner 4.2) for 1.35x the tokens; a one-sentence prompt of the same format scores almost as well

xlsx (anthropics/skills)

20.3 / 30

SituationalSafe

anthropics xlsx: its recalculation script never ran on a Mac, and the skill scored slightly lower than no skill
