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

Orchestrate AI coding agents (Claude Code, Codex, OpenCode) in isolated sandboxes using the @ai-hero/sandcastle SDK. Use when the user needs to (1) run agents AFK in Docker/Podman containers, (2) build multi-agent pipelines with plan-execute-review patterns, (3) run parallel agents on separate worktrees, (4) create iterative agent loops with maxIterations, (5) extract structured output from agent runs, (6) set up sandcastle in a new or existing project, or (7) write prompt files with template a…

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/'sandcastle' ] || [ -L ~/.agents/skills/'sandcastle' ]; then echo 'A skill folder named sandcastle already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/av/skills' "$d" && git -C "$d" checkout --quiet '8f70341629e3871b17c34b54aca27e02bf1d4b49' -- 'sandcastle' && mkdir -p ~/.agents/skills && cp -R "$d"/'sandcastle' ~/.agents/skills/'sandcastle' && 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/'sandcastle' ~/.claude/skills/'sandcastle' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
