Extending AI with Agent Skills 2026 (Udemy.com)

The course touches on an important aspect of interacting with LLMs: what text you send as context and how LLMs handle it. Ultimately, every agent/framework formats your text (e.g., system prompt, skills, tools, etc.) into an array of messages and feeds it to the LLM. Knowing that and how it works makes a huge difference in getting the best results from your generative/agentic AI project.

The content is great, but I had trouble seeing the video and your website is difficult to navigate to find support, especially while in the middle of a course. Suggestion is to add some direct "Need help?" links within your video player, because I honestly thought for the first 10 minutes that it was only text on a black screen by choice. Turns out CC was on and without that I would've been unable to follow much. So, just a suggestion - I'm sure lots of people have this same issue (Hardware acceleration was on).

There were a few moments when I was not sure the course was for my zero level, but in the end we got there. Quite helpful, and in the end I learned what I need to do to create my first skill in Anthropic, for example!

In general a good course. Good build up with theory leading to usage. Course seems short but it was adequate. I was missing some hands-on in between like writing a simple skill earlier on and a more complicated one later. Also some course material with tips and links would have been nice.

Another great Tony Alicea course! This course helped me better UNDERSTAND Agents Skills, including how they work, how I can use them and how I can BETTER create them. The consistent, successful model Tony uses for his courses, integrating Big Word Alerts and Conceptual Asides, draws me to purchase his courses when I'm interested in finding out HOW something works and not just implementing it. Thanks again Tony!

I chose to create an Agent Skill that helps users complete a specific task more efficiently by giving clear guidance, organizing information, and producing useful responses. The skill is designed to understand the user’s request, break it down into steps, and provide helpful output that saves time and reduces confusion. By building and using an Agent Skill, I learned how important it is to give clear instructions so the agent understands the goal and responds accurately. I also learned that an Agent Skill can be useful for automating repeated tasks, improving productivity, and making information easier to understand. Testing the skill helped me see how small changes in instructions can improve the quality of the responses.

Great course!!! It really helps to understand the mental model and fundamentals around SKILL.md Course also explains well important technical terminologies with "Big Word Alert". I appreciate the effort from Author of the Course

When we talk about AI courses, specially those related to LLMs and such, the great majority of courses are really shallow in content, focusing in aspects that only someone who had zero contact with the technology would find useful or interesting. This course surprised me positively by being short, well paced and focusing on an aspect that really makes a difference when working with AI: creating good, well written skills. Kudos to the creator.

I really liked how the course simplified the topic that a non-technical person can understand and have appropiate infleuences that nudges course recipient to become a skill builder in a open source way and help the community of skill builders leveraging available AI agents.

This course is excellent for understanding what skills are and how to build them effectively. The explanations are simple and easy to follow, the pace is just right, and the examples are very well chosen and clearly explained. Overall, a very well-structured course for anyone looking to develop a strong foundation in this area.
