Antigravity vs GitHub Copilot — FAQ

Should I pick Antigravity or GitHub Copilot?

It depends on where you work. Antigravity is agent-based development environment, while GitHub Copilot is microsoft's ai pair programmer across editors. Many developers use both and share skills across them via BuySkills — so the choice is less binary than it used to be.

Can I use the same plugins in Antigravity and GitHub Copilot?

Yes. BuySkills is designed for cross-agent portability. Install a skill once with the BuySkills CLI and it becomes available in both Antigravity and GitHub Copilot — and every other supported agent — without a second purchase or install.

How is installing BuySkills skills different between Antigravity and GitHub Copilot?

It isn't, from your side. You run `npx buyskills install <skill>`, and the CLI writes the skill to the directory each agent reads from. Antigravity and GitHub Copilot pick up the skill without any extra config.

How do I add skills to Antigravity?

Install BuySkills CLI and run `npx buyskills install <skill>`. The CLI detects Antigravity and writes skills into the directory its agent reads at startup. Restart the agent loop (not the whole app) to pick up new skills.

Can BuySkills skills be used with GitHub Copilot agent mode?

Yes. Copilot agent mode can invoke local skills registered through BuySkills as part of its multi-step plan. The BuySkills CLI registers skills in the paths Copilot's agent reads from during execution.

Still deciding?

Install BuySkills CLI once and the skills you discover today work in whichever agent you pick tomorrow.
