How to Build Custom AI Agents in the Theia IDE
Want to automate your daily workflows with AI - without writing any backend code? In this demo, we show how to create a custom AI agent from scratch using the AI-powered Theia IDE, based on Theia AI.
But this time, we go beyond code: We walk through building an agent that converts exported Markdown blog posts (from Google Docs) into the proper format for our Hugo-based website—including:
✅ Filling in metadata like author and tags
✅ Rewriting internal and external links
✅ Embedding images correctly
✅ Checking grammar and formatting
✅ Updating backlinks across the site
The best part? This all happens inside the IDE using a custom agent, configured just through a prompt template. No code development required!
🎥 Watch the video to see:
- How to create a new agent inside the Theia IDE
- How to define a custom prompt and reuse tooling from other agents
- How the agent interacts with your local workspace using Theia AI tool functions
- Why this workflow shows the power of task-focused, domain-specific AI agents
