Augment (Skills & MCP)
Out of the box, a coding agent can read and write files. That's about it. It can't open your app, can't click through it, and knows nothing specific about the libraries we picked. This lesson fixes both gaps: we give the agent a browser so it can test its own work, and we install skills that teach it our exact stack.
What you'll walk away with:
- Giving the agent browser access through the Playwright MCP
- Testing browser automation and full end-to-end workflows the way a real user would move through the app
- What skills are actually for, and when they beat cramming more into your rules file
- Finding and installing skills from skills.sh
- Adding skills for Better Auth, Next.js, React and our project workflow
- Choosing between a project-level and a global installation, and when each one is the right call
An agent that can open your app and check its own work is a different thing to one that just writes code and hopes.
