Your Claude Skills Now Work in Antigravity (Here's How)
Your agent skills are finally platform-agnostic

If you’ve been building Claude Code skills for your co-writer system, you’re basically done. Google Antigravity just added support for agent skills, and the internet is treating it like some brand new thing. It’s not. It’s the same structure you already know.
In this video, I show you exactly how to take your existing skills and drop them into Antigravity with one folder name change.
By the end, you’ll have:
The folder structure difference — literally the only thing that changes between Claude and Antigravity
A working skills library — your entire Claude skills folder ported over
A skill creator skill — so you can build new skills directly in Antigravity
Access to Anthropic’s official skills — the full library works in Antigravity too
My honest take — whether you should actually switch (spoiler: probably not)
If you’ve been following along with my co-writer content, this is a quick win. If you’re new, this shows you why building skills is such a powerful approach.
Everybody’s talking about Anti-Gravity skills like Google invented something new. But this is really just the result of Anthropic open-sourcing the entire practice of using agent skills. If you’ve been building these in Claude, you already know how to do this.
Here’s what’s actually cool about this: the consolidation around agent skills as a practice means you can bounce between tools without rebuilding your entire system every time. Your skills are portable. Build once, use everywhere.
For non-developers doing professional work, this is huge. You’re not locked into one platform. The skills you build for content creation, marketing, writing workflows — they all transfer. That’s the power of building reusable assets instead of collecting prompts.
The only thing that changes
In Claude Code, your skills live in a .claude/skills/ folder. In Antigravity, they live in a .agent/skills/ folder.
That’s it. That’s the entire difference.
Same skill structure inside. Same SKILL.md file. Same optional folders for scripts, examples, and resources. Just a different parent folder name.
The skill follows the same format:
Name and description at the top
Detailed instructions in the body
Optional supporting folders
If you have a skills library built for Claude Code, you literally copy the skills folder, paste it into .agent/, and you’re done.
Progressive disclosure pattern
Both Claude Code and Antigravity use what’s called progressive disclosure for skills. When a conversation starts, the agent automatically sees a list of available skills with their names and descriptions. It looks for any that match your task, activates the relevant ones, reads the full content, and executes based on those instructions.
Same behavior. Same pattern. This is why your skills transfer without modification — the agents are reading and executing them the same way.
The key here is that your skill names and descriptions matter. They’re how the agent decides whether to invoke the skill. Make them clear and specific.
Why I’m not switching
After about 48 hours experimenting with Antigravity, I’m staying with Claude Code for my own writing system.
Claude Code just works better. I can have all my subagents, all my skills, my entire system built out in there. It functions more smoothly. In Antigravity, I ran into bugs, things didn’t work as cleanly, and I don’t have much faith in Google fixing those issues quickly.
That said, if you prefer Antigravity or your team is already using it, this video shows you how to bring your skills over. The tools work. You can build a good co-writer system in there. I just happen to think Claude Code is still the better option for this kind of work.
