Notice of "Claude Co-work for Beginners" Course Renewal (v2.0)

Hello, students.

As some features and screens have changed with the July 2026 Claude update,

We are renewing the lecture materials and videos to reflect the latest standards.

The update for Lesson 2 has now been completed, and

The remaining lectures are scheduled to be updated all at once within this week (by August 9th).

■ Update Completed

[Lesson 2 · Claude Environment Map]

- Reorganized environment categories from 5 → 4 (Web / Office Add-in / Desktop / Mobile)

- Redefining Cowork as a "mode selectable from the input window" rather than the "fifth environment"

- Completely replace the feature comparison table for each environment based on the latest support scope

- Reorganizing all slides + re-filming the corresponding sections

■ Scheduled updates for this week

[Lecture 3 · Claude Web Basic Settings]

- Replaced the removed Styles feature with an explanation of Memory

- New guide added for 4 model types (Haiku / Sonnet / Opus / Fable) + 5 levels of Effort

- Reorganizing practice steps to match the updated settings screen, such as the model selection location.

[Lesson 4 · Effective Prompts + Research]

- Reflected the integration of the 'Thinking Mode' toggle into Effort

- Reorganized into two axes: "How far to search (Web Search OFF / ON / Research)" and "How deeply to think (Effort)"

- Added guidance on the latest information cutoff date for each model

[Lesson 6 · Projects + Context Management]

- Reflecting changes in Memory behavior (from once-a-day summary → real-time recording during conversation)

- Organizing personalization priorities and updating the hands-on practice workflow

[Lecture 16 · First Appearance of Cowork]

- Reflected that Cowork has expanded to web and mobile, rather than being a separate tab in the desktop app

- Organizing criteria for where tasks are executed (Cloud / My Computer)

[Lecture 17 · Schedule + Dispatch]

- Reflecting the change where scheduled tasks now run in the cloud

→ Tasks that do not use files from your computer will run even if the PC is turned off.

- Reorganized the guide on execution conditions and registration methods

[Lesson 18 · Live Artifacts]

- Reflected changes where functions remain the same but menu and button names on the screen have changed

[Common to all lectures]

- Terminology unification: Project Instructions → Project 지침, Project Knowledge → 컨텍스트

- Corrected parts where screen names or paths have changed based on the current screen (excluding some practice sessions)

■ Information regarding the Record a skill feature

The 'Record a skill' feature, which creates skills through screen recording, is

is currently provided exclusively for macOS.

Considering that most students practice in a Windows environment,

it was not covered in this renewal.

If it becomes supported on Windows in the future, we plan to add it through a separate update.

(There are two ways to create a skill: 'Create through Conversation' and 'ZIP Upload' from the existing lecture,

Windows users can also follow along with the practice in the same way.)

We will announce again as soon as the update is complete.

We will return with more accurate and up-to-date content. Thank you.

Hello, this is Rookiss.

The interactive textbook series has been in production since July.
- Introduction to Claude Code (Cursor will also be added to this week's lecture) https://inf.run/DqW9T
- Claude Harness https://inf.run/zrKXB
- Introduction to CS https://inf.run/fcJpz
- Introduction to Python https://inf.run/1etHe

Now that the basic lineup is complete, I plan to move on to intermediate & advanced lectures for a while.
- In August, Mathematics (Functions/Calculus/Linear Algebra/Probability & Statistics) lectures.
- Starting from September, DX12, Network Engines, etc., are scheduled.

Society has become truly difficult due to AI.
As a result, I've been receiving many questions regarding career paths and studies lately.
Last Sunday, I held a seminar on the direction of study that I envision,
so please refer to Rookiss Live Seminar: Tower of Rookiss for more details.

Hello!

1. Regarding the release of the first lecture based on interactive teaching materials

   
   After studying Claude Code, a minimum level of CS knowledge is required for development.
   In this lecture, we focus on easily mastering the computer science fundamentals for Claude AX development by visualizing all content through a unique 3D production method.
   
   https://inf.run/frmoX
   

   

   Take a look at this new-concept textbook created with heart and soul!
   

2. Regarding Benefits for Existing Purchasers
   For those who have already enrolled in the previously released [KDC] Rookiss's Pinpoint Lesson - Introduction to Claude Code,
   we plan to automatically provide this course even if you do not enroll in it separately. (This will be processed through Inflearn inquiries tomorrow.)
   The KDC course was uploaded for government-funded promotion scheduled to start in September,
   but more people than expected have been purchasing it at a high price(?).
   Therefore, we would like to offer the benefit of receiving additional upcoming Claude Code course series as well.

   
   
   Thank you!

This course was designed for working office professionals, and structured in a way that does not provide separate class materials or prompts (learning principles and methods to apply directly to the workplace).

However, in response to feedback that job seekers, students, and non-office workers currently outside the workforce are having difficulty practicing, we will provide all practice materials (reports, proposals, contracts, email contents, Slack conversation history, meeting minutes, etc.) and prompts (practice guides) used in this lecture.

Except for students who have no choice but to use the practice materials, we urge those currently working in the field to proceed with the course assignments by applying them directly to the materials you use in your actual work, rather than relying on the provided practice materials.

All practice materials have been updated.
