What it does

In the author's own words, from each skill's SKILL.md.

  • startup-user-simulator

    Simulate how five plausible customer personas experience a startup, SaaS, app, or landing page, explain why each would convert, hesitate, or leave, and produce a polished standalone HTML report. Use when Codex needs to test a live URL, localhost app, screenshot, prototype, or landing-page copy for positioning, first-impression clarity, relevance, trust, objections, conversion friction, CTA effect…
