Claude Code
Codex
Cursor
GitHub Copilot
Gemini CLIAbout this skill
Invoke when comparing models or prompts and you want evidence, not a vibe check — choosing a model for a task (opus vs sonnet vs haiku; Claude vs Codex vs Gemini), A/B testing prompt variants, running a model/prompt bake-off or eval, or confirming a prompt change actually helped rather than got lucky. Runs a controlled A/B/n experiment: one variable, the same test cases through every arm, N replicates for stochastic noise, a blinded judge, a pre-registered metric and decision rule, and an honest "is the gap beyond noise?" — not "B felt better." Starts with a Claude adapter; extensible to Codex/Gemini.
