What it does

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

  • contrarian

    Use when stress-testing a proposal, plan, architecture or decision before committing to it, such as pre-mortems, assumption audits, "should we even do this?" questions, or when everyone agrees too easily. Not for code review; it challenges strategy, approach and hidden risks.

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.
