Agent Skills in Claude Code and Visual Studio Code: Setup, Benefits, Risks, and a Step-by-Step Example

Image
 AI coding assistants are useful for one-off questions, but many development tasks are not one-off tasks. A team may follow the same testing procedure before every release, use a specific format for code reviews, or require certain checks whenever a database migration is created. Repeating those requirements in every prompt is inefficient. Putting all of them into a permanent instruction file is not always ideal either, because the assistant may receive irrelevant information for tasks that do not need it. This is the problem that Agent Skills are designed to solve. A skill packages reusable instructions, supporting files, examples, and optional scripts into a folder. Claude Code or GitHub Copilot in Visual Studio Code can discover that folder and load its contents when the current task matches the skill’s purpose. Both environments support the open Agent Skills format, which makes it possible to share some skills across tools. This guide explains what skills are, how they differ ...

About Vibe Coding Insider



Vibe Coding Insider is a practical guide to building software with AI, created for non-developers, beginner programmers, and experienced developers adapting to AI-assisted development.

I hold a Ph.D. in Computer Science, with a research background in data indexing and information retrieval. Over the past 15 years, I have worked as a full-stack developer across multiple software companies, building and maintaining real-world applications.

I currently work as a tech lead at a company in Canada, where I lead software projects and help development teams make technical decisions. During the past year, I have also used GitHub Copilot and Claude Code as part of my day-to-day product development workflow.

My recent book, Practical Code Review in the Age of AI: Review Like a Senior, explores how developers can review AI-generated code with the same care, judgment, and discipline expected from experienced engineers.

Through Vibe Coding Insider, I share practical tutorials, development workflows, code review techniques, tool insights, and honest observations about the rapidly changing world of AI-assisted software development.

The goal of this blog is not to suggest that AI can replace software engineering knowledge. It is to help readers use AI coding tools more effectively, understand the code they generate, avoid common mistakes, and turn ideas into reliable software.

Claude Code Multi-Agent Setup for Beginners: Models, Roles, and Your First Project

Image
A single AI coding assistant can plan a feature, write code, run tests, and review the result. However, asking one agent to perform every responsibility in the same conversation can make the workflow difficult to control. A simple multi-agent setup gives each agent one clear role. For a beginner project, four agents are enough: PM Agent → Architect Agent → Developer Agent → QA Agent The PM defines what should be built. The Architect decides how it should be structured. The Developer implements one task at a time. The QA Agent checks whether the result meets the requirements. This setup does not require a complicated autonomous system. Claude Code remains the main coordinator and delegates focused work to each custom agent. Version note: Claude Code commands, model names, agent frontmatter fields, and available model identifiers may change. Before using the examples, check the current /agents and /model menus and compare them with the latest official Claude Code documentation. Recomm...

The Limits and Future of Vibe Coding

Image
Vibe coding can shorten the distance between an idea and a working application. A person can describe a feature in natural language, ask an AI coding assistant to inspect a project, generate code, explain an error, write tests, or prepare deployment files. Tasks that once required hours of manual typing may begin with a short conversation. That speed is real, but it can be misleading. Generating code quickly is not the same as defining the right product, building a maintainable system, protecting user data, or proving that the software works. As AI coding tools improve, the human role does not disappear. It moves toward requirements, judgment, review, testing, architecture, and accountability. This final article looks beyond the Personal Reading List Tracker and examines what vibe coding can do well, where it remains limited, and which skills will matter as AI-assisted development continues to evolve.

How to Test and Deploy Your First Vibe-Coded App

Image
Reaching the point where an application appears to work on your computer is an important milestone. It is not the same as being ready to publish. A vibe-coded application may behave correctly during one successful demonstration while still containing broken edge cases, missing files, exposed development data, incorrect paths, or behavior that changes after deployment. Testing and deployment should therefore be treated as separate stages. Testing asks: Does the application behave as intended under normal and unexpected conditions? Deployment asks: Can other people access the verified version in an environment outside my computer? This article walks through a complete release process for the Personal Reading List Tracker. We will test its primary workflows, inspect the repository, prepare a release checkpoint, deploy it as a static website, verify the live version, and create a recovery plan.
