90 / 100 · Low risk

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

Use when the user wants to try Kreuzberg Cloud without signing up, or needs an ephemeral key for evaluation, demos, or CI integration tests. Covers POST /v1/sandbox/key — the no-auth endpoint, quota, TTL, and cleanup expectations.

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/'sandbox-keys' ] || [ -L ~/.agents/skills/'sandbox-keys' ]; then echo 'A skill folder named sandbox-keys 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 "$d" checkout --quiet '3e1e6b20ffc28f42923e391f29f075c424e19e64' -- 'plugins/kreuzberg-dev/plugins/plugins/kreuzberg-cloud/skills/sandbox-keys' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/kreuzberg-dev/plugins/plugins/kreuzberg-cloud/skills/sandbox-keys' ~/.agents/skills/'sandbox-keys' && 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/'sandbox-keys' ~/.claude/skills/'sandbox-keys' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
