What it does

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

  • duel

    Have an OpenAI model challenge Claude's answer, then defend or revise it through a short evidence-led debate. Use for "duel this with ChatGPT", "face off this answer", or an explicit request for a second model to critique an answer.

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
