test-driven-development
80 / 100 · Low risk
Fine to try.
Use when implementing a feature, fixing a bug, or changing behavior — write a failing test first, watch it fail, write minimal code to pass, then refactor. Adds Kent Beck's Tidy First (separate structural vs behavioral changes) and a Canon test list. Language-agnostic core; per-language notes under references/languages/. Not for throwaway prototypes, generated code, or pure config changes (ask first).

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=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '6d2e63f73f845eb5dd94c1debba627d4b6e32fba' -- 'plugins/yyykf/spellbook-skills/skills/test-driven-development' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/yyykf/spellbook-skills/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.
