Install

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

if [ -e ~/.agents/skills/'harness-work' ] || [ -L ~/.agents/skills/'harness-work' ]; then echo 'A skill folder named harness-work already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/tim-hub/powerball-harness' "$d" && git -C "$d" checkout --quiet 'cf086c6a667d37610d30a4236b94d8ab02e4efc5' -- 'harness/skills/harness-work' && mkdir -p ~/.agents/skills && cp -R "$d"/'harness/skills/harness-work' ~/.agents/skills/'harness-work' && 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/'harness-work' ~/.claude/skills/'harness-work' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
