With your agent
Install OMGSkills skill "garrytan/gstack:benchmark-models" into this agent's normal skills directory: use the OMGSkills MCP get_skill tool, install only the pinned_install commit and path, verify SKILL.md against pinned_install.skill_md_sha, and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/garrytan/gstack /tmp/gstack && ln -s /tmp/gstack/benchmark-models ~/.claude/skills/benchmark-modelsFrom 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) Read the echoed KEY: value STATUS lines — they drive every preamble rule below.
