95 / 100 · Low risk

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

You MUST use this before writing or changing any production code, including one-line fixes and when the user is in a hurry: a new feature, a bug fix, a refactor, a behavior change. Write the failing test first, run it and watch it fail for the right reason, write the minimal code that passes, then run the whole test suite before saying it is done. Skip it only for throwaway prototypes, generated code or configuration-only changes, and only with the user's OK.

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/'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=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/davila7/claude-code-templates' "$d" && git -C "$d" checkout --quiet 'a6e6f93e9a4baaa6ff337aee5505bf5c2bae4ce6' -- 'cli-tool/components/skills/development/test-driven-development' && mkdir -p ~/.agents/skills && cp -R "$d"/'cli-tool/components/skills/development/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.
