[Feature] Add support for Google Antigravity Skills

[PIGzyj233]

Reasoning
This would allow users to invoke impeccable’s design auditing and steering capabilities natively within the Antigravity agent context, similar to how it currently works with Anthropic's format.

Can confirm that skills do not work in Antigravity even though it's marketed as such.

ye how do the skills show up when installed globally? dk how to use :/

I added a note to the site thinking Antigravity just doesn't support slash commands, but as of today, they seem to work fine:

Could you please test again? Make sure your project directory has a .agents folder in it. When in doubt, clone the impeccable repository (now has all provider skills loaded itself) to test.

Not an OP, but I can confirm that using npx skills add pbakaus/impeccable and installing the skills in the .agents file make the skills work in Antigravity.

[pbakaus]

thanks @fslick, I'll close this issue then. Please reopen if anyone is still running into issues.

[tazztone]

it shows up as slash command when npx skills add is run as "Installation scope │ Project"
.agents/skills/

but nothing shows up when it is installed globally
/home/tazztone/.agents/skills

have to symlink them into
/home/tazztone/.gemini/antigravity/skills

FWIW, I think this stopped working again after Antigravity 2.0 was released.

I'm gonna try and see how OpenSpec does it and maybe come up with a PR (if no one else beats me to it).

thanks, that would be great! not sure what broke there. I don't think we're doing anything fancy for Antigravity..

I gave it a shot in #281
