Agent skill fromrampstackco/claude-skills
Designing side-by-side comparison tools (plan-compare, product-compare, alternative-compare) that help users decide rather than just listing features. Axis selection, default-comparison logic, recommendation discipline. Honest about feature-list-dump (every feature in a row, no decision support), hidden-recommendation (biased comparison pretending to be neutral), and honest-comparison-with-guidance (genuine comparison plus opinionated recommendation) patterns. Triggers on comparison tool, plan compare, product compare, alternative compare, vs page, decision support tool. Also triggers when conversion through comparison stages is poor, when users are abandoning at the comparison step, or when a comparison tool is being scoped for the first time.

1# Comparison Tool Design23A senior product marketing director's playbook for designing side-by-side comparison tools that help users decide rather than just listing features. Plan-compare, product-compare, alternative-compare. Axis selection, default-comparison logic, recommendation discipline. The discipline of building a comparison tool that earns the user's trust.45Most comparison tools fail in one of two ways. They dump every feature into a giant grid (4 options × 40 features = 160 cells) and ask the user to weigh everything against everything. The user leaves without choosing. Or they pretend to be neutral comparisons but are actually sales pitches with biased defaults and weighted framing; the user catches the bias and trust collapses.67The comparison tools that work do something different. Genuine like-for-like comparison plus an explicit opinionated recommendation. "For X audience, choose Y." The recommendation is visible, defended, and not the only path; users can override. The tool helps the user decide rather than asking them to decide alone.89The voice is the senior product marketing director who has watched comparison tools double conversion when redesigned with honest recommendations and watched them collapse when feature grids grew without decision support. Practical, opinionated about which axes matter, willing to call out when the comparison is decoration.10…
