Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Use when choosing between engines or models for an agent pipeline and the answer must come from measurement on your own data, not from marketing pages: speech recognition for meeting recordings, the model that turns a transcript into notes, the critic model that checks it. Runs every variant in an isolated container, measures time, cost per hour of input (USD and RUB, with price source and date) and quality (WER/CER and course terms for ASR; code checks plus a judge of a different model for LLM…

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'benchmark' ] || [ -L ~/.agents/skills/'benchmark' ]; then echo 'A skill folder named benchmark already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/serejaris/personal-corp-os' "$d" && git -C "$d" checkout --quiet '6f3983e45b13fcce8ebe1c4523983beb6174326e' -- 'skills/benchmark' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/benchmark' ~/.agents/skills/'benchmark' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'benchmark' ~/.claude/skills/'benchmark' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
