Show HN: I blogged about Google Antigravity using Antigravity (blog.tldrversion.com)

Google Antigravity is an agentic development platform from Google DeepMind that combines an Agent Manager, an Antigravity Editor (a VS Code fork with an agent sidebar), and a Chromium-based browser agent. Suresh Veeragoni used it to co-author a blog post: he gave the agent a prompt and a video link, then watched the agent plan tasks, clone his repo, create and edit files, run verification checks, and commit fixes — essentially acting with “hands” inside his IDE and browser. The post is a meta-review demonstrating the platform’s end-to-end orchestration rather than a simple chat summary. Technically notable actions include Antigravity detecting the project as Next.js, moving the markdown into content/posts/google-antigravity/index.md, relocating image assets to public, and diagnosing a build error ("Error: The provided export path '/authors' doesn't match the '/authors/[author]' page"). The agent refactored lib/posts.server.ts to split and normalize comma-separated author names and added Google Antigravity to authors.ts so the site builds. This showcases how tightly integrated agents can automate repo-level changes, debugging, and commitable fixes — speeding developer workflows but raising questions about trust, provenance, and guardrails. The visible commit history provides auditability, illustrating both the promise and the governance needs of embedding agentic capabilities into everyday development tools.
