playground

100 / 100 · Low risk

Fine to try.

By melodic-software/claude-code-plugins (GitHub) · coding · 30 stars · scanned at commit 230251c

Creates interactive HTML playgrounds — self-contained single-file explorers that let users configure something visually through controls, see a live preview, and copy out a prompt. Use when the user asks to make a playground, explorer, or interactive tool for a topic.

Works with any agent that supports SKILL.md skills.

Install

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

if [ -e ~/.agents/skills/'playground' ] || [ -L ~/.agents/skills/'playground' ]; then echo 'A skill folder named playground already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/melodic-software/claude-code-plugins' "$d" && git -C "$d" checkout --quiet '230251cc750b562576c144d595b7cc0fabfceae9' -- 'plugins/playgrounds/evals/use-shadowed-name-is-not-invoked/playground-stub/skills/playground' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/playgrounds/evals/use-shadowed-name-is-not-invoked/playground-stub/skills/playground' ~/.agents/skills/'playground' && 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/'playground' ~/.claude/skills/'playground' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
