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

アプリのテストはすべてこのスキルを使う。開発中のTDD（テストファースト）から、ユーザー目線のE2E・受入テスト、インフラ/デプロイ検証、リリース前の網羅テストまでを1つに統合。「テストを書いて」「テストして」「動作確認して」「TDDで進めて」「カバレッジを確認」「E2Eテスト」「リリース前にちゃんとテストしたい」「本番で動くか確認」「回帰テスト」などの文脈で必ず使用する。§0「適用段階」に従い、たたき台〜v1 では「壊れたら困る順」の最小テスト、固定化段階(v1 到達後のブラッシュアップ)ではユーザーがテストと明示しなくてもTDDサイクルを適用する。セキュリティ・コスト・パフォーマンスの監査は Skill launch-security を併用する。

Install

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

if [ -e ~/.agents/skills/'testing-excellence' ] || [ -L ~/.agents/skills/'testing-excellence' ]; then echo 'A skill folder named testing-excellence already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/daishiman/harness-dev' "$d" && git -C "$d" checkout --quiet '3e1b394bd699e07d0b030acd44ee12f9143f89eb' -- '.agents/skills/testing-excellence' && mkdir -p ~/.agents/skills && cp -R "$d"/'.agents/skills/testing-excellence' ~/.agents/skills/'testing-excellence' && 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/'testing-excellence' ~/.claude/skills/'testing-excellence' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
