Is the Agy CLI skill free?

Yes. The skill itself is free from georgekhananaev/claude-skills-vault. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Agy CLI SkillProof Score?

8.4/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install Agy CLI?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Agy CLI with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 8.4/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · bc7def7

⚠ Security: it recommends --dangerously-skip-permissions as the standard pattern for delegated runs; the skill documents the risk, but keep it sandboxed. agy itself isn't installed and needs an interactive OAuth login no agent can complete, but both bundled scripts ran for real and failed exactly as documented (agy_preflight.sh exited 1 with 'agy not found', agy_run.sh exited 3 the same way) -- and that same test exposed a real bug: the skill's own recommended invocation hardcodes the relative path '.claude/skills/agy-cli/scripts/agy_run.sh', which does not resolve once the skill is installed globally to ~/.claude/skills/agy-cli, the exact install path this benchmark's own protocol requires.

What Agy CLI does

Wraps Google's Antigravity CLI (agy, Gemini 3 based with Claude/GPT model access) with a heartbeat-guarded background runner that kills silent stalls in under 3 minutes instead of blind-waiting up to 45, plus a preflight script for updates, model reporting, and config repair. Triggers when the user wants Claude to run/delegate a build, refactor, audit, or second-opinion task to Gemini's agentic CLI via its default-chat, /grill-me, or /goal effort tiers.

How to install Agy CLI

git clone https://github.com/georgekhananaev/claude-skills-vault
cd claude-skills-vault
mkdir -p ~/.claude/skills
cp -r .claude/skills/agy-cli ~/.claude/skills/agy-cli

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
