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

Test and evaluation harness for AI agents — scenario suites, deterministic replay, regression diffing, cost and latency budgets. Use when agent quality is vibe-checked, before shipping a prompt or model change, or when evals drift.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'agent-harness' ] || [ -L ~/.agents/skills/'agent-harness' ]; then echo 'A skill folder named agent-harness already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/borghei/Claude-Skills' "$d" && git -C "$d" checkout --quiet '25bf86b89c6c1e63f433a5b65e8cfcb6cf0b7ad3' -- 'engineering/agent-harness' && mkdir -p ~/.agents/skills && cp -R "$d"/'engineering/agent-harness' ~/.agents/skills/'agent-harness' && 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/'agent-harness' ~/.claude/skills/'agent-harness' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
