test-driven-development

80 / 100 · Low risk

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

By event4u-app/agent-config (GitHub) · coding · 19 stars · scanned at commit 3445cf4

Implementing a feature, fixing a bug, refactoring — failing test first, then the code. For a WRONG test, `testing-anti-patterns` wins.

Works with any agent that supports SKILL.md skills.

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

if [ -e ~/.agents/skills/'test-driven-development' ] || [ -L ~/.agents/skills/'test-driven-development' ]; then echo 'A skill folder named test-driven-development already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/event4u-app/agent-config' "$d" && git -C "$d" checkout --quiet '3445cf41d6db4b369392dc6fbf7e78a2774e17b5' -- 'src/skills/test-driven-development' && mkdir -p ~/.agents/skills && cp -R "$d"/'src/skills/test-driven-development' ~/.agents/skills/'test-driven-development' && 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/'test-driven-development' ~/.claude/skills/'test-driven-development' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
