collaborating-with-antigravity

69 / 100 · Review before installing

Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

By appautomaton/agent-designer (GitHub) · coding · 133 stars · scanned at commit b6e95dc

Delegate tasks to Google's Antigravity CLI (agy) for prototyping, debugging, code review, and research. Supports multi-turn sessions via SESSION_ID. Successor to the retired Gemini CLI.

Works with any agent that supports SKILL.md skills.

Safer alternatives

Low-risk skills in the same category (coding) that look related. Check that one does what you need.

Install

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

if [ -e ~/.agents/skills/'collaborating-with-antigravity' ] || [ -L ~/.agents/skills/'collaborating-with-antigravity' ]; then echo 'A skill folder named collaborating-with-antigravity already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/appautomaton/agent-designer' "$d" && git -C "$d" checkout --quiet 'b6e95dc063a29830ecd131f5171f3d14c66017f7' -- 'skills/collaborating-with-antigravity' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/collaborating-with-antigravity' ~/.agents/skills/'collaborating-with-antigravity' && 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/'collaborating-with-antigravity' ~/.claude/skills/'collaborating-with-antigravity' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
