Antigravity

Verified rules packs, agent skills, MCP servers and plugins for Google’s Antigravity IDE — plus the deprecated Workflows migration guide.

Antigravity is Google’s agentic IDE — the coding surface where Gemini does the work rather than answering questions about it.

Its extension surface is markdown-native: rules packs shape how the agent writes and refuses work, skills teach it repeatable procedures, custom agents specialize its behavior, MCP servers hand it tools it does not ship with, and plugins extend the editor itself.

That is also what makes the ecosystem reviewable — nearly everything here is a file you can read before you install it, which is exactly how this site verifies entries: not against star counts or README promises, but against the artifact itself.

One structural note: workflows are deprecated upstream (May 2026) in favor of Agent Skills; the workflows hub is kept as migration reference, with the deprecation state marked rather than hidden.

Everything else is organized by the same official customization concepts the product documents — and where a community convention outgrows them, the entries say so rather than forcing the taxonomy.
