harness
77 / 100 · Review before installing
Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.
Harness runs coding agents (Claude Code, Codex and others) as harnesses, sessions the person can watch and join in the Harness app, on this computer or their other machines. Use it to start another agent on work that can run beside yours, needs another agent's view (a review, a second opinion from Codex), takes long, or belongs in its own folder; then wait for it, read its answer and close it. Do small, quick work yourself, and quick fan-out inside one task with your own sub-agents.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'harness' ] || [ -L ~/.agents/skills/'harness' ]; then echo 'A skill folder named harness already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/autonomous-ai/openharness' "$d" && git -C "$d" checkout --quiet '92aa7660f44e222456248fc9ad16ed0e0f19d43f' -- 'plugins/harness/skills/harness' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/harness/skills/harness' ~/.agents/skills/'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/'harness' ~/.claude/skills/'harness' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
