Fine to try.

Run work on short-lived Boat sandboxes with the `bx` CLI and steer it with herdr. Use when a task needs a clean Linux machine, more parallelism than this Mac allows, or isolation between runs (evals, test shards, agent trials that share /tmp, ports or a browser), or when the user says box, Boat, sandbox, spawn a machine or run it remotely.

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/'bx-boxes' ] || [ -L ~/.agents/skills/'bx-boxes' ]; then echo 'A skill folder named bx-boxes already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/enitrat/skill-issue' "$d" && git -C "$d" checkout --quiet '6cddc7e22fe4df16c3203d51e983ffdb99506d1b' -- 'skills/bx-boxes' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/bx-boxes' ~/.agents/skills/'bx-boxes' && 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/'bx-boxes' ~/.claude/skills/'bx-boxes' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
