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

Run a crew of coding agents from one controller (also /crew): lanes send READY blocks and never merge; the controller merges through trains, keeps the digest, relays approvals, fixes flakes daily. (gstack)

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/'captain' ] || [ -L ~/.agents/skills/'captain' ]; then echo 'A skill folder named captain already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/garrytan/gstack' "$d" && git -C "$d" checkout --quiet 'bc858ffc659bcc61558f60d0e023a009817dd48f' -- 'captain' && mkdir -p ~/.agents/skills && cp -R "$d"/'captain' ~/.agents/skills/'captain' && 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/'captain' ~/.claude/skills/'captain' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
