Automating Bilingual Blog Posts with Custom AI Skills in Google Antigravity

Writing bilingual blog posts has always been a time-consuming challenge. Translating content, adjusting structures, and maintaining the original context often require significant effort. To solve this, I built an automated workflow leveraging Google Antigravity IDE paired with Supabase and Vercel.

In this post, I will share how I created a custom skill .agent/skills/write-hoan-blog/SKILL.md that completely revolutionizes my blogging process.

The System Architecture

My modern blogging stack is built on the following technologies:

• •Google Antigravity IDE: An AI-powered integrated development environment where I define custom protocols for autonomous agents.
• •Supabase: A powerful PostgreSQL database that stores the bilingual markdown content seamlessly.
• •Vercel: The robust deployment platform hosting the Next.js frontend to securely serve these dynamic posts to readers.

How the Custom Skill Works

The write-hoan-blog skill acts as an intelligent, autonomous editor. The automated workflow involves:

1. •Taking the Input: I simply provide the topic and main ideas via the chat interface.
2. •Drafting and Polishing: Instead of a robotic translation, the AI takes the prompt and structures a professional-grade post in both English and Vietnamese, preserving technical terms appropriately.
3. •Preparing Metadata: It automatically generates SEO-friendly s, punchy s for social sharing, and calculates the estimated reading time.
