Fine to try. Some of what it can do is expected: a productivity skill usually connects to your mail, calendar or notes.

Plans and tracks tasks in .claude/harness/plans.json. Use when creating plans, adding tasks, updating markers, checking progress, or brainstorming an idea into tasks.

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/'harness-plan' ] || [ -L ~/.agents/skills/'harness-plan' ]; then echo 'A skill folder named harness-plan 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 "$d" checkout --quiet 'cf086c6a667d37610d30a4236b94d8ab02e4efc5' -- 'harness/skills/harness-plan' && mkdir -p ~/.agents/skills && cp -R "$d"/'harness/skills/harness-plan' ~/.agents/skills/'harness-plan' && 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-plan' ~/.claude/skills/'harness-plan' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
