benchmark-models

From README

When to invoke this skill Runs the same prompt through Claude, GPT (via Codex CLI), and Gemini side-by-side — compares latency, tokens, cost, and optionally quality via LLM judge. Answers "which model is actually best for this skill?" with data instead of vibes. Separate from /benchmark, which measures web page performance. Use when: "benchmark models", "compare models", "which model is best for X", "cross-model comparison", "model shootout". Voice triggers (speech-to-text aliases): "compare models", "model shootout", "which model is best". Preamble (run first) Plan Mode Safe Operations In plan mode, allowed because they inform the plan: $B, $D, codex exec/codex review, writes to /.gstack/, writes to the plan file, and open for generated artifacts. Skill Invocation During Plan Mode If the user invokes a skill in plan mode, the skill takes precedence over generic plan mode behavior. Treat the skill file as executable instructions, not reference.
