Gravitas: open-source skill makes Google Antigravity agents check their assumptions in 4 languages
alexcovo_eth · x · 2026-10-12
Developer Emily released Gravitas, a free MIT-licensed add-on for Google Antigravity. It makes the AI agent check what its answers depend on, kindly flag wrong user assumptions, and still deliver the requested result.
- Natively multilingual: unlike most skills written in English then translated, Gravitas was designed from the ground up to be native in English, Chinese, Japanese and Korean.
- Positioning: a fact-checking / prompt-engineering agent skill, with one-click installers for Mac and Windows, docs, and tests in the repo.
- The project is early-stage (3 stars), but worth a look for developers exploring agent skill design and the Antigravity ecosystem.
