Mastering Claude Code: From AI Development Workflow Basics to Real-World Practice

Hello, this is Gym Coding.

First of all, I would like to express my sincere gratitude to everyone who is taking the Claude Code course.

To be honest, I didn't expect so many people to love this course. Currently, a total of 2,005 students are with us, and every time I read the reviews you've thoughtfully left, I can feel how seriously you are all approaching your studies.

The Inflearn team also mentioned that it is very unusual for so many students to show interest in such a short period of time, and we even held a separate meeting. All of this is thanks to you, the students.

Thanks to you, I am continuing to refine the lectures with a mindset of "I need to make this even better."

With that in mind, I have prepared a major update. In fact, it's not just once, but twice.

1⃣ First Update

"Directly reflecting Q&A from over 2,005 students into the lectures"

We have conducted a complete analysis of all the questions and troubleshooting issues submitted by students so far. In this update, we are incorporating these insights directly into the lectures.

• Partial changes to existing lecture video content (reflecting updated specifications, screens, etc.)

• Adding new videos to existing lectures (supplementing missing explanations and advanced content)

We will directly address the setup issues, errors, and environment-related problems that have frequently appeared in the Q&A section within the lecture videos. You no longer need to search through the Q&A; simply follow the lectures.

2⃣ Second Update (Scheduled for mid-February)

"Claude Opus 4.6 + Full Integration of Latest Features"

With the recent release of the Claude Opus 4.6 model, Claude has become noticeably smarter. Accordingly, I plan to include the newly added powerful features in the lectures.

Among them, the Agent Teams feature that many of you have been asking about!

It is a feature where multiple Claude Code sessions form a team to collaborate simultaneously, and it is truly powerful.

Since Agent Teams is currently still an experimental feature, I plan to include it in the lecture only after I have spent enough time personally practicing and verifying it through various scenarios. This is because I do not want to convey unverified information.

It will be covered in the second update, so please look forward to it😊

📝 Changelog to be released

We are releasing the Changelog as well.

📅 Update Schedule Announcement

Both updates are scheduled to be completed within February.

Current work in progress:

• Identifying and organizing the latest Claude Code specifications

• Analyzing existing student Q&A and organizing points for reflection

• Exploring various workflows to share with students by personally testing the latest features in different ways.

I will continue to keep students updated on the progress and specific schedule through the news section.

Once again, thank you so much for choosing this course and staying with me until the end. I believe these updates are only possible because of all of you.
