90 / 100 · Low risk
Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.
By diegopacheco/ai-playground (GitHub) · coding · 21 stars · scanned at commit d9a66a7
Generate ephemeral catching tests on the current diff, run them, and report behavior regressions. Tests are never committed. Works across Java, Kotlin, Scala, Python, and Node.js stacks.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'jit' ] || [ -L ~/.agents/skills/'jit' ]; then echo 'A skill folder named jit already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/diegopacheco/ai-playground' "$d" && git -C "$d" checkout --quiet 'd9a66a7614b743615074ea74689ae2039fadcb2d' -- 'pocs/jit-testing-skill' && mkdir -p ~/.agents/skills && cp -R "$d"/'pocs/jit-testing-skill' ~/.agents/skills/'jit' && 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/'jit' ~/.claude/skills/'jit' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
